The Playing Fields: Sports and Warfighting Readiness

By Phil Bozzelli and Paul Giarra

The Duke of Wellington’s aphorism “The Battle of Waterloo was won on the playing fields of Eton,” has been widely accepted as a validation of sports and their greater relevance to warfighting and victory. We take that statement at face value but go further.

Using the renewed emphasis upon warfighting within the defense and naval establishments, we propose that sports at our service academies, especially the U.S. Naval Academy, do more than provide venues for exercise or competition. Rather, those activities and their participants should be an integral part of the warfighting curriculum of those institutions just as everything else there should be.

This theme leverages the basic relationships between sports and warfighting. In the former one needs to know and understand himself, his teammates and his opponents. It is no different in warfare, where the stakes are higher and therefore the knowing and understanding of one’s self, allies and enemies is of even greater importance for success. Warfare thinking and action are focused upon the international environment.

The global population has embraced sports as a way to improve understanding and relations between nations. The Olympics are the most obvious manifestation of this reality. We have all witnessed how this venue has become, over the decades, a demonstration of either national pride, wealth, political ideology, or a combination of all as well as other positives and negatives. These gatherings have, as a minimum, permitted an up-close and extended engagement by and among the individual athletes themselves.

America does bring foreign officers to the U.S. for training and education exchange programs. Some exchanges involve officers at the more senior levels whose thinking has already been largely shaped and is done in a generally formal classroom environment. This schooling process includes little participation of America’s less friendly counterparts and for the most part it takes place on American soil.

USNA has 33 varsity sports at the national competition level and 25 intramural and club sports for those not competing at the varsity level. America’s other service academies operate similar programs (e.g. West Point offers 25 varsity sports and 28 intramural and club teams). All midshipmen (and cadets) are engaged in one or more sports or athletic activities, but essentially all on the domestic scene.

This sporting, intramural, and club scene is dynamic not only in content but in venue and physicality. The digital age has introduced E-Sports, gaming and wargaming as competitive processes that fill stadiums and require superb hand-eye coordination analogous to that of professional basketball players but while seated at a computer screen. The games have transitioned from general games to those that mimic live sports as well and they too have transitioned to international levels of competition monitored by its version of the NCAA (Global Esports Federation – GEF). Similarly, the military-focused wargaming genre has joined this digital competitive environment.

The National Defense Academy of Japan (NDAJ) manages to field 37 sports at various levels (even including traditional American sports like football, basketball, etc.). USNA (and USMA) have about the same number of students as at the NDAC with the major difference being that the NDAJ offers a three-year education to future officers of all services before they go on to separate one-year schools for their individual militaries.

To varying degrees, militaries have officer-based sporting teams at different levels of skill within and without the primary service school. The Indian Navy has the largest naval academy in Asia and offers at least nine sporting teams. The Royal Navy, in addition to sports teams at its Naval School, fields a vast variety of teams throughout its naval establishment. China’s PLAN sporting focus, as can be determined from afar, appears to be more of a utilitarian team building type, although it does field a seriously respected rugby team. Interestingly, the PLA has not lagged in joining the digital age of competition, with E-Sports and wargaming popular among its military and civilian schools.

The various USNA teams should engage internationally with their friendly and not-so-friendly international military equivalents. The numbers of USNA teams provides significant engagement opportunities at varying appropriate skill levels dispersed over the entire calendar year. An environment exists where competition can be fair and appropriate as well as useful to help produce the warfighting leadership of the future. This proposed international engagement via sports far exceeds that international experience available to midshipmen from any other current program. It is on the international fields and seas where these officers will engage in war and peace.

We do not wish to engage here in a debate regarding how strong the warfighting focus has been of the USNA in recent years. However, it is clear that “warfighting” is currently being emphasized. The newly installed Secretary of Defense has made clear his focus and emphasis is upon warfighting and war readiness. This echoes the previous Chief of Naval Operations in her 2024 Navigation Plan for its “Warfighting Navy” headline and focus.

There is a renewed awareness and focus upon warfighting ability and readiness as the primary, if not singular, mechanism for maintaining peace. As one of the nation’s commissioning sources of naval officers the burden is upon USNA not only to support but to lead in this warfighting mission via its classrooms, dormitories and playing fields.

We are not starting from ground zero. The USNA offshore sailing team recently competed and won at the Ecole Navale International Sailing Week Competition, and in May 2024 the USNA had part of its men and women rugby teams participate in a State Department sponsored Rugby 7 tour of Fiji, Samoa and Tonga. We are proposing an organized expansion of these efforts not just for the sport but for the inherent benefit it brings to America’s national security via the education of its future Naval leaders in meeting the USNA mission that the naval officer “must be a great deal more.”

Our interest in this subject came about when we became involved on the periphery of an invitation from the NDAJ’s four-star level civilian head to the USNA rugby team, via its coach, for the team to join in a rugby tournament at the NDAJ that would include teams from the NDAJ, the UK (Royal Naval College) and France (Ecole Navale). USNA’s Rugby team’s schedule and other factors (e.g., financing, event timing, NCAA rules etc.) precluded USNA participation.

We must first call attention to and highlight the significance of this NDAJ rugby initiative given the historical political and societal factors operating in that nation. We see sports related thinking as a “big deal.” The NDAJ rugby initiative not only reinforces the transnational utility of sports but offers a focused interpersonal engagement vehicle for military forces – friendly and not – which the U.S. and U.S. Navy should leap upon and expand. The more important aspect is the engagement with non-friendly nations.

The NDAJ and USNA catalog of sports is more typical than not of what exists at the world’s various service academies. Further, and more importantly, is the global shift in military attitudes exemplified by the Japanese government’s more visible foreign policy on the world’s stage to include this invitation to both the USN and its major seagoing allies via their officer producing schools.

Our contention is that it is all about warfighting to include having the necessary warfighting skills to achieve success without war. In the words of Wellington, “Not all naval battles are fought at sea!” Once one accepts this dictum, the tradeoffs required in terms of time and funding between these events and more traditional activities of Midshipmen (e.g. summer cruises) can be more equitably evaluated.

The “whys” for doing this are probably limited more by experience than imagination, so we list but a few of the more obvious. Whether one is a “globalist” or not, the reality is that America’s military has been involved globally since its founding and this is especially true of its sea services – the Navy, Marine Corps and Coast Guard – whose officers are expected to function as diplomats in their international engagements, even at junior levels. Doing this well requires more international engagement sooner and over a longer period of service time.

The history of the world and certainly that of America from its beginning has made clear the need for supporters, friends, allies, partners regardless of whether the objective is military, political, economic or diplomatic. Whether that non-American shows up as a ship in our formation, a soldier in an adjacent fox hole, an article in some foreign media, a vote in some organizational chamber, some piece of needed foreign real estate or overflight, a trading partner or lender or simply an unpretentious “flag” among many – we all know and accept this need and the utility of someone to satisfy it. Perhaps, even more importantly, we appreciate that we must nurture these relationships if they are to be maintained or improved upon. For the military officer, this is not about “good will” or “friendships” it is about what is required in terms of knowledge about both allies and possible enemies.

For the naval officer this relationship between knowledge and warfighting is lifelong and consistent. It begins at USNA with its motto Ex Scientia Tridens (From Knowledge Sea Power), engraved on every USNA graduate’s class ring. It continues and is reinforced with the U.S. Naval War College motto of Viribus Mari Victoria (Victory through Sea Power); and these academic guidons become seagoing reality in the U.S. Seventh Fleet’s Ready power for peace.

The authors’ experiences have been that there has been and remains a great deal of ignorance and misunderstanding of what transpires in the minds and cultures of others. This deficiency occurs at all institutional levels, public and private. Therefore, being able to make critical judgments regarding what others present becomes ever more important as the pace and sourcing of information is growing exponentially. While critical thinking ability is essential for the domestic environment as well, our focus is warfighting wherein both the opponents and allies will be foreign.

A major, if not the greatest, impediment to international success and a contributor to contentions has been ignorance or misunderstanding of the history, culture, motivations, beliefs, psychology of others. A deficiency compounded in this modern era where English is the new global lingua franca. Because American “culture” (e.g. Apple, pop music, entertainment) is dispersed to the furthest corners of the globe and all are joined together via the Internet and social media, we therefore assume, incorrectly, that others think and are motivated as we are.

Despite varying bloody, military conflicts since World War II’s VJ day, the vast majority of America’s military effort, and especially that of its Navy, has been on peaceful non-kinetic engagement with neutrals, friends, allies, opponents, competitors around the world. All of these actions are either directly or indirectly pointed to enhancing that warfighting prowess to be there when needed and be visible and accepted so as not to be needed.

Although the NDAJ and rugby were the impetus for this article, the opportunities are more extensive and the demand pressing enough that the U.S. and especially the U.S. Navy should take a leadership role in making this happen using the hype created by the Olympics, international athletic competition, and the ever-present forces necessitating “gray zone” engagement. As demonstrated repeatedly, sports allow engagements where otherwise precluded by politics.

This puts the NDAJ invitation in a different light, not just as a friendly school-to-school athletic challenge, but as an opportunity for international exposure, country-to-country understanding, and bonding with friends and allies. And to emphasize the earlier points, this is not just about Japan or Rugby but the broader opportunities across all sports and all nations for a deliberate military to military engagement program in a different sort of classroom and “battlefield.”

Clearly, there are requirements that would have to be met, such as funding, carving out time in already packed academic and sports schedules, and meeting NCAA restrictions. Held against the international opportunities for building personal and professional relationships and improving understanding among all parties, these are not obstacles, but simply the cost of doing business. It is probably not an exaggeration to state that all that takes place in the lives of Midshipmen is geared to turning them into competent naval officers, citizens, and leaders. Consequently, the time allocated to these various endeavors is justified and valid as is the funding, regardless of its source (e.g. government budgets, donations, alumni funding, sports revenue etc.)

These are all costs that need to be sourced. However heavy the financing thumb is on the scale, it should be balanced by potential gains, financial and otherwise. Depending upon where and how these contests are conducted there is the opportunity for revenue such as from advertising, broadcasting and tours. Neither USNA nor the U.S. government itself are novices in this category. On that same counterweight side of the scale are the intangible benefits of image, recruiting across the board, good will, cultural understanding and messaging all done via the more acceptable and less intrusive vehicle of sport.

Although this proposal is directed at the junior levels of the military, our experience has been that a shared background of military service provides a degree of basic rapport that often does not exist between the military and civilian of even the same nation. This is especially true for the sea services where the impartiality of the seas, winds and skies allows one ship’s captain to readily baseline himself with another regardless of nationality. Similarly, competitive athletes at all ages have this shared understanding among their international colleagues. A boxer or wrestler or oarsman or whatever knows, appreciates and has a common foundation with his fellow competitor regardless of nationality because the common vigor of the shared sport transcends borders. Thus, there is an important starting framework from which to go forward – shared naval schooling background combined with common sporting experience.

Basically, getting to “Yes” will include understanding by U.S. leaders that this is both an internal and external political – military issue of great significance. We recommend the following:

1. Begin with “Of course we will participate” and find a way.

2. Start early, quickly and small – focus upon a successful beginning.

3. As with the launching of ships, it is important to “grease the skids” at all stakeholder levels, from coaches to national governments to funders to help ensure success

4. Following on to the NDAJ receptivity and initiative regarding Rugby, Rugby may be the logical beginning; however, pursuing this as the first step may violate the above idea of “early, quickly and small.”

5. The U.S., U.S. Navy, and the U.S. Naval Academy have so many options in terms of sports, timing, venues (domestic and international), and opponents that it is difficult to see an obstacle to an early success once the decision is made to participate.

6. There are several way to fund this program: Academy supporters, athletic and team supporters, patrons, corporations, U.S. DOD and non-DOD funds.

7. Planning around academic year class schedules is difficult, but not impossible. Summer cruises can be designed around team participation as is done now for major sports; venue selection can facilitate the time required for the event. Therefore, we see this as a year-round activity.

8. Treat this program the same as Olympic team participation. There are clear precedents for scheduling and funding for military personnel.

9. Recommendation 1, above, to participate, is not enough: Lead!

Finding a way requires the collaboration of many parties. However, the leadership initiative rests with the Superintendent of the U.S. Naval Academy who has authority for the human resources required for this program and whose staff includes an International Engagement Office, which may need expansion in both depth and breadth to develop and execute a successful program.

There will be various arguments as to why the above is either too difficult or unnecessary. We address three:

1: NCAA rules: important enough to USNA’s Division 1 status and all that goes with it to have a compliance officer on the USNA Athletic Association staff to ensure the coaches adhere to the rules. However, as any tourist to Annapolis will see on display in either a souvenir shop or on the back of a midshipman tee shirt the logo “USNA, not college”. Within and without the USNA, there needs to be a reminder that the service academies have a purpose that goes beyond and sometimes conflicts with that of just being a major educational institution. Further, there are NCAA rules, such as the transfer portal entry, that the USNA is not able to employ. If the USNA becomes serious about executing this proposal, working the NCAA rules process to satisfy all requirements is probably achievable.

2: USNA’s to-do list: that USNA’s superintendent has much to do and adding something else such as this to that work list is counterproductive. The US government and the US Navy furnishes the Superintendent with a significant sized staff to include an already existing International Engagement Officer. We acknowledge that there is no shortage of projects being thrust upon the USNA leadership; however, we think all these endeavors, whether new or traditional, first need to be evaluated and prioritized accordingly by the leadership, writ large, before being rejected. As addressed above, we see the USNA’s primary mission as being that of educating and training entry level naval officers in a manner consistent with the missions of the operating fleet and its other educational institutions. Under this logic every opportunity to educate midshipmen within the framework of warfighting makes sense as an element of the USNA mission.

3: Vehicles, such as CISM (International Military Sports Council) already exist to do such: therefore, use that mechanism rather than something new or different. For reasons best known to USNA, the institution has had no noticeable participation via CISM. Those reasons would certainly have included obstacles such as the NCAA rules, financial support, schedules etc.

While useful in part within that structure, the NDAJ rugby invitation and its acceptance by others sends the message that other vehicles exist, are used and are probably preferred. The recent USNA sailing competition in France and the USNA Rugby 7 tour of some of the South Pacific islands are but two examples. Perhaps most importantly are the objective and who leads.

The objective is to enhance warfighting prowess of America’s Naval Forces. Objectives of such institutions as CISM (The ultimate goal is to contribute to world peace by uniting armed forces through sports. The motto under which we operate is “Friendship through Sport) or even that motivating the USNA Rugby 7 tour of the South Pacific (“to enhancing our partnership with the Pacific Islands and the respective governments to achieve our shared vision for a resilient Pacific Islands region of peace, harmony, security, social inclusion, and prosperity) are all well and good but should not and cannot be the objectives of military forces. We say this with full appreciation that a competent warfighting military force can certainly help produce the environment for these other outcomes, as reflected in the US Seventh Fleet’s maxim “ready seapower for peace,” but the operative action is power – seapower and warfighting ability.

The ability of America’s military to perform its primary function – defense of the United States and its objectives – will, as always, depend upon the skills and willingness of its military leaders to lead – to lead internally and externally. Without denigrating the utility, value, importance of friends, allies and international cooperation, the reality – welcomed or not – is that the external world for the foreseeable future is looking to and expecting U.S. leadership. Therefore, we expect America and its naval leadership to lead here as well.

We close with this reminder – “Not all naval battles are fought at sea!”

Countering the People’s Republic of China’s Maritime Insurgency in the South Pacific

By Jason Lancaster

Guadalcanal, the Coral Sea, Tarawa, New Guinea, and Iron Bottom Sound highlight the strategic location of the South Pacific during the Second World War. Today, U.S. and allied preeminence in this vital region is under threat. The People’s Republic of China (PRC,) through a sophisticated blend of economic inducements, political influence, and maritime coercion, is executing a campaign to erode U.S. and allied presence and reshape the Indo-Pacific order. Such activities mirror the tactics of insurgency, where control is gained not just through force, but by blurring legal boundaries, exploiting economic vulnerability, and using civilian fronts to advance strategic ends.1

The PRC’s maritime insurgency is not limited to the South China Sea. It is a global phenomenon. This maritime insurgency is not fought with gunfire but with corruption, development loans and aid, and the PRC’s deep-water fishing fleet. More than 17,000 vessels fishing throughout the world routinely engage in Illegal, Unreported, and Unregulated Fishing (IUUF), often acting as a civilian vanguard for PRC state objectives. The situation is particularly acute in the South Pacific, where Chinese fishing fleets exploit the limited enforcement capacity of Pacific Island Countries (PICs), deplete sovereign marine resources, and undermine local economies, eroding governance, and sovereignty in the process. 

The South Pacific is by no means a strategic backwater. It lies astride the sea lines of communication connecting U.S. treaty allies in Japan, South Korea, the Philippines, and Australia.  It is home to key U.S. territories such as Guam and American Samoa. It includes the Compact of Free Association (COFA) states Micronesia, Palau, and the Marshall Islands. At its heart are the fourteen Pacific Island Countries. possess rich marine resources, and command strategic real estate that could either anchor regional stability or serve as launchpads for malign influence.2

Historically, the U.S., Australia, and New Zealand have been the region’s primary security and development partners. However, since 2018, the PRC has dramatically expanded its presence building dual-use infrastructure, embedding security arrangements, and offering opaque development assistance. Despite sustained Western aid to these nations, Beijing’s influence has surged. The construction of Chinese-funded ports and runways in the Solomon Islands and Kiribati. Long range missiles stationed in the Kiribati or the Solomons could threaten Hawaii, Australia, and the continental U.S., compromising freedom of navigation, eroding regional deterrence, and challenging the U.S. ability to defend treaty partners Japan, South Korea, and the Philippines.

IUUF is a major threat to PIC economies. Fishing is a major contributor to many PIC economies and IUUF challenges the ability of states to create revenue, further condemning them to a future of dependency on international development aid. The United States can enhance its hard power in the Indo-Pacific by utilizing soft power to counter IUUF and provide humanitarian assistance, thereby denying PRC regional influence.

Countering IUUF

The United States does not need to develop a new engagement strategy with South Pacific nations from whole cloth. The Pacific Island Forum produces its own strategic documents. Composed of 18 members and associate member states, the Pacific Islands Forum (PIF) serves as a unifying voice for the small states of the South Pacific. Australia and New Zealand are full members while U.S. territories Guam and American Samoa are associate members. The 2050 Strategy for the Blue Pacific Continent and the 2018 Boe Declaration on Regional Security articulate shared South Pacific security concerns and development goals. The United States and its allies are already adopting PIF strategic documents for engagement with Pacific Island Countries to achieve mutual successes. 

Countering IUUF and other forms of transnational crime is a top PIF priority, second only to climate change and rising sea levels. While the United States pays signatory nations US$60 million a year over ten years for the privilege of fishing within PIC Exclusive Economic Zones (EEZs) under the South Pacific Tuna Treaty,3 the PRC flagrantly disregards the sovereignty of Pacific Island states while plundering their maritime bounty. Pacific Island nations do not have the capacity to police their expansive EEZs against massive fishing fleets without assistance.

Pacific Fusion Center

The PIF’s 2018 Boe Declaration recommended various security proposals to defend PIF interests. One was the development of a Pacific Fusion Center to support the collation, sharing, and analysis of intelligence. The Pacific Island Forum stood up a Pacific Fusion Center in Vanuatu in 2021. The fusion center “enhances information sharing, cooperation, analysis and assessment, and expands situational awareness and capacity across the Pacific.”4 The fusion center provides an opportunity to expand multinational cooperation in the region and expand defense and security force capacity. To successfully counter transnational crime, the U.S. should support and increase the capacity of the Pacific Fusion Center with the mid-term goal of turning it into a maritime headquarters, increase the capacity to enforce PIC EEZs and laws, and increase regional maritime domain awareness fed into the Pacific Fusion Center.

Through US associate PIF members Guam and American Samoa, the U.S should offer USCG support for the center to immediately increase its effectiveness. With a mid-term goal of creating a PIC-led multilateral maritime headquarters like the Combined Maritime Forces headquarters in Bahrain, this multinational maritime headquarters would be rotationally led by PICs with Australian, New Zealand, and U.S. support, and would have tactical control of forces regionally assigned to countering transnational crime.

The Pacific Fusion Center will not be effective without forces at sea enabling maritime domain awareness (MDA). MDA supports two vital interests: enabling US, Australian, New Zealand, and local PIC forces to intercept and eliminate IUUF, and monitoring the PLAN in the region. IUUF fleets are vast. This was illustrated off South America, in February 2025, when the Argentine Navy tracked over 380 PRC flagged fishing vessels near the Argentine economic exclusion zone, requiring Argentina to send two warships and two aircraft—a sizable portion of its deployable blue water forces—to monitor these fishing vessels.5 The United States can support MDA through multiple asset types to identify potential threats within the maritime domain, supporting both the Pacific Fusion Center and a PIF response at sea.6 

Improving Capacity

Most PICs have little capability to enforce their own EEZs. Australia’s mitigation for the PIC’s lack of resources is the Pacific Maritime Security Program. This security assistance program provides Guardian-Class patrol boats, an equivalent of the USCG’s fast response cutter (FRC), along with crew training and maintenance for every PIC.7 The program has provided a total of 22 patrol boats over 30-year program. This effort has been a mixed success, as the region is full of marked and unmarked reefs and multiple ships have met with accidents. In December 2024 the new Fijian patrol boat RFNS Timo was damaged while docking. Timo is a replacement vessel for RFNS Puamau, which hit a reef and sank in June 2024.8 Timo completed her first patrol in April 2025.9 Despite this program many of these countries still do not have the capacity to patrol the entirety of their EEZs. The geography is a demanding one—the EEZ of Kiribati is roughly the size of the continental United States. The RAN and RNZN also have capacity issues. The RAN and RNZN serve dual functions, conducting both war at sea and law enforcement missions. The RNZN’s new force design will reduce the availability of RNZN vessels to conduct regional constabulary duties.

The US Coast Guard (USCG) faces budgetary and ship number restrictions, but they are the regions preferred US service for cooperation. With local agreements, the USCG can help increase regional capacity. USCG District Oceania, formerly District 14’s area of responsibility is the Pacific with ships based in Honolulu and Guam. The USCG has two national security cutters, one medium endurance cutter, three Fast Response Cutters (FRCs), and three buoy tenders stationed in Honolulu, as well as three FRCs and a buoy tender based in Guam. The U.S. Navy supports USCG missions as able. These efforts are primarily focused on the U.S. and COFA state EEZs. USCG ships are responsible for patrolling thousands of miles of both U.S. and COFA EEZs. The distances involved are vast: it is 850 miles from Guam to Palau and over 5,000 miles from Honolulu to American Samoa. In addition to fisheries protection, these cutters are also responsible for counter-narcotics, smuggling, other law enforcement requirements, and search and rescue.10

The United States must increase its regional naval presence to reassure citizens, partners, and potential partners. Utilizing USCG assets reassures regional allies and partners while minimizing the threat of escalation with the PRC, reducing fears and potential misgivings of U.S. intent. The United States should increase USCG District Oceania’s assets by relocating four Fast Response Cutters currently homeported in Bahrain to the South Pacific. The increased presence of Littoral Combat Ships in U.S. Central Command’s area of responsibility would mitigate the reallocation of the four FRCs. 

Eradicating IUUF

Increased and improved provision of command and control and MDA and increased capacity to intercept IUUF fishermen is required for the eradication of IUUF. Officials at the New Zealand embassy stated that there were not sufficient naval forces in the region to enforce EEZs across the multitude of countries. Legal action offers an essential tool to deter further incursions despite limited forces at sea.

PICs should be provided legal, domestic, and security assistance to prosecute transnational crime. Most PRC fishing captains work for state owned enterprises tied to important CCP bosses. Linking senior CCP party members to illegal behavior that costs PIC citizens jobs, money, and resources for the future could be a method to end IUUF as well as deter future PRC illegal activities. Convictions in absentia after fair public trials are a method to deter PRC activity and highlight PRC malign influence. 

Healthcare and Pacific Partnership

Medical support is one of the most frequently requested forms of aid from PICs. The U.S. Navy’s Pacific Partnership is hugely popular in the region and provides life-changing care. The popularity of the mission should drive the U.S. and allies to increase the frequency of visits with increased allied support. USNS Mercy does not participate every year, but there has been an attempt at her participation every two years.

The Department of Defense should discuss RAN, RNZN, and Japanese Maritime Self-Defense Force support for increasing the number of Pacific Partnership missions. Although none of these navies have a dedicated hospital ship like USNS Mercy, each nation has a ship suitable for these missions and the capacity to send a single vessel for a 3–4-month humanitarian deployment to the South Pacific. A planned rotation of USN, RAN, USN, RNZN, USN, JMSDF provides a six-year cycle that enables maintenance, training, and other operational requirements to be scheduled. The U.S. off-years would still see U.S. mission support with a ship as well as medical personnel. U.S. years would have USNS Mercy support.

The Navy should hub a medical expeditionary ship (T-EMS) in Yap, Federated States of Micronesia to support smaller scale but persistent humanitarian medical support in the region. These vessels contain one or two operating rooms and are extremely suitable for this mission because of their shallow draft and hospital level facilities and ability to embark helicopters. The T-EMS’s sister ships, the fast expeditionary transports (T-EPFs) have been frequently used for Pacific Partnership stations, demonstrating the utility of this class for use in the South Pacific.

Conclusion

The South Pacific region holds immense strategic value for the United States and its allies. Located at the heart of key U.S. alliances and territories, the region has drawn increasing attention from the PRC, whose maritime gray zone insurgent activities threaten to undermine regional security, economic stability, and political alignment.

The PRC’s deepening engagement with PICs, particularly through dual-use infrastructure, strategic partnerships, and coercive economic practices has shifted the balance of influence away from traditional allies like the United States, Australia, and New Zealand. The potential for Chinese military assets in Kiribati or the Solomon Islands should be viewed as a severe threat to U.S. territories and Indo-Pacific allies. Coupled with increased PLAN presence and aggressive operations, this trend signals a challenge to U.S. freedom of movement and regional dominance.

To effectively counter this encroachment, the U.S. must commit to a comprehensive, multi-pronged strategy that integrates regional security support, humanitarian assistance, and institutional cooperation. Expanding the Pacific Fusion Center will strengthen intelligence sharing and regional coordination and MDA. Increased USCG presence would deter illegal activities like unregulated fishing and support local law enforcement capabilities. These efforts should be pursued in partnership with Australia, New Zealand, and other like-minded nations to promote regional ownership and reduce perceptions of neocolonial influence.

Combating transnational crime, particularly illegal, unreported, and unregulated fishing requires not only physical presence but also legal and political resolve. Holding senior PRC officials accountable through international legal mechanisms can deter further violations and reinforce the rule of law. In parallel, bolstering regional healthcare through expanded Pacific Partnership missions and sustained medical presence such as stationing a T-EMS in Micronesia will address urgent humanitarian needs and enhance U.S. soft power. Ultimately, securing the South Pacific is not solely about countering PRC influence. It involves empowering Pacific Island Countries, reaffirming the United States’ commitment to its allies, and ensuring that the region remains free, open, and resilient.

It’s Time to Invite Taiwan to RIMPAC

By Jim Halsell

The Taiwan Strait remains one of the most volatile flashpoints in the world. With the People’s Republic of China (PRC) accelerating its coercive behavior aimed at “reunifying” Taiwan with the mainland, the United States must adopt a clearer, more deliberate strategy to bolster deterrence and reassure regional partners. One measure that should be taken is to include Taiwan in the world’s largest multinational maritime exercise – the Rim of the Pacific (RIMPAC). Doing so would be consistent with U.S. policy under the Taiwan Relations Act, align with the values of collective defense and democratic solidarity, and signal to Beijing that any use of military force against Taiwan will result in a unified, multinational response.

Taiwan’s Strategic Significance

Taiwan occupies a central position in the First Island Chain and plays a crucial role in the balance of power in East Asia. It is a thriving democratic society of 23.4 million people and a key node in global semiconductor supply chains. Beijing’s claim to the island is tenuous, supported by a campaign of intimidation and “gray zone” tactics that aim to coerce Taiwan into capitulation without war.

Though lacking official recognition as an independent country by the United States and many of its allies, Taiwan is not isolated. U.S. policy, as codified in the 1979 Taiwan Relations Act (TRA), commits the United States to make available “defense articles and defense services in such quantity as may be necessary to enable Taiwan to maintain a sufficient self-defense capability,” and to “maintain the capacity of the United States to resist any resort to force or other forms of coercion that would jeopardize the security” of the people of Taiwan. Inclusion in RIMPAC would help operationalize this policy while remaining consistent with the U.S. One China policy.

Why Include Taiwan?

Deterrence requires both capability and credibility. While Taiwan continues to acquire U.S. military hardware and reform its defense posture, the question of whether the United States and its allies would support Taiwan in a contingency remains deliberately ambiguous. Strategic ambiguity may help manage escalation risk, but it risks failing to deter if Beijing concludes that the costs of aggression are tolerable.

Involving Taiwan in RIMPAC would signal a broader multinational investment in regional peace. Beijing is pursuing two parallel lines of effort to pressure Taiwan: coercion without violence and the looming threat of military force. Both avenues can be countered through stronger integration with partners, transparent signaling, and public commitments to Taiwan’s survival as a free society.

The inclusion of Taiwan in RIMPAC would not require diplomatic recognition of Taiwan as a sovereign state. RIMPAC has previously included diverse participants with some participating only as observers. Taiwan could be invited under a similar framework—e.g., “Taipei Navy—Observer”—that would align with RIMPAC precedent, and would not constitute formal U.S. recognition. It would, however, reinforce the deterrent message that a conflict in the Taiwan Strait would not remain a bilateral issue between Washington and Beijing.

Reinforcing the Taiwan Relations Act

The TRA provides a clear legislative foundation for actions that enhance Taiwan’s defense and deter coercion. The Act affirms that “the United States will consider any effort to determine the future of Taiwan by other than peaceful means…a threat to the peace and security of the Western Pacific area and of grave concern to the United States.”1 Participation in exercises like RIMPAC would help Taiwan prepare for defense without crossing the line into formal alliance, thereby avoiding a breach of the One China policy.

Congress continues to reaffirm bipartisan support for Taiwan’s self-defense. The FY2025 National Defense Authorization Act (NDAA) includes provisions to strengthen military cooperation and enhance deterrence through initiatives like the Taiwan Security Cooperation Initiative. Including Taiwan in exercises alongside Japan, Australia, and other regional partners would be a natural extension of these legislative efforts.

Operational and Symbolic Value

Beyond signaling, there are tangible military benefits. Taiwan’s military operates U.S.-made systems and is transitioning toward an asymmetric defense model, emphasizing survivability and denial. Interoperability with U.S. and allied forces, especially in joint maritime operations, will be essential in any scenario short of or including conflict.

As the Council on Foreign Relations notes, “Taiwan likely doesn’t have the capabilities to defend against a Chinese attack without external support,” despite pledging nearly $20 billion in defense spending for 2025.2 Enhancing operational coordination before a crisis emerges is not only prudent, but operationally essential.

Symbolically, inclusion in RIMPAC would acknowledge the democratic values that Taiwan shares with other regional partners. This is particularly important as Taiwan remains diplomatically isolated, with only eleven countries maintaining official relations. Participation in multinational military activities would help offset this isolation without provoking conflict, provided it is managed diplomatically and clearly communicated.

Would Other Nations Support Taiwan’s Inclusion in RIMPAC?

One of the central concerns surrounding Taiwan’s potential inclusion in RIMPAC is whether key U.S. allies and regional partners would support such a move or whether they would balk at the political risk of antagonizing the People’s Republic of China. However, recent geopolitical trends suggest that support for Taiwan’s participation in multinational defense activities is quietly growing, particularly among Indo-Pacific democracies that share an interest in preserving regional stability and resisting Chinese coercion.

Japan is perhaps the most likely partner to welcome Taiwan’s inclusion. Tokyo has become increasingly vocal about the importance of Taiwan to Japan’s national security, with senior officials, including former Prime Minister Shinzo Abe, stating that “a Taiwan contingency is a Japan contingency.” Japan’s Self-Defense Forces have increased coordination with the U.S. military and have participated in bilateral and trilateral exercises that implicitly prepare for scenarios involving Taiwan. Given Japan’s growing anxiety over China’s assertiveness and its own constitutional reinterpretation on collective self-defense, Tokyo would likely support Taiwan’s inclusion in a multilateral setting like RIMPAC, especially if coordinated in advance with careful diplomatic messaging.

Australia has also strengthened its strategic alignment with the United States and Japan, particularly through the AUKUS agreement. Canberra has voiced concerns about China’s regional behavior and recently joined Washington in emphasizing the importance of peace and stability in the Taiwan Strait. While Australia might be more cautious about formal diplomatic gestures, it is unlikely to oppose Taiwan’s participation in a non-sovereign capacity, especially if framed as a security-enhancing measure rather than a political endorsement.

Other Indo-Pacific states, such as India, Philippines, and Vietnam, have growing interests in counterbalancing Chinese maritime assertiveness. India has long advocated for a multipolar Asia and may view Taiwan’s inclusion as consistent with its own efforts to build regional coalitions. The Philippines, under President Ferdinand Marcos Jr., has deepened security ties with the United States and allowed expanded access to military bases in response to PRC aggression in the South China Sea. Vietnam, while traditionally wary of foreign alignments, has clashed with China over maritime claims and may be open to Taiwan’s inclusion in an observer or limited functional role.

European states that have participated in recent RIMPAC iterations such as France, Germany, and the United Kingdom have also increasingly signaled concern over Taiwan’s security. They conducted transits of the Taiwan Strait, and their defense white papers mention the Indo-Pacific as a zone of strategic interest. While these countries may not be vocal advocates for Taiwan’s inclusion, they would be unlikely to withdraw or protest if the decision were led by the United States with appropriate multilateral coordination.

Ultimately, the determining factor may be how the invitation is framed. If Taiwan’s participation is defined not as a sovereign equal to other states but rather as a security partner or “participant entity,” other nations could find it diplomatically palatable. This would mirror Taiwan’s existing participation in multilateral forums such as the Olympics, the World Trade Organization and the Asia-Pacific Economic Cooperation forum, where it joins under the name “Chinese Taipei.”

RIMPAC’s Flexible Participation Model

RIMPAC’s long history as a multinational exercise underscores its diplomatic flexibility. Since its inception in 1971, RIMPAC has included a diverse array of participants, including states with varying degrees of political alignment with the United States, non-ally partners, and even, at times, strategic competitors. This precedent offers a viable pathway for Taiwan’s inclusion without triggering a fundamental break in U.S. policy or alienating key participants.

A notable example is the People’s Republic of China, which was invited to participate in RIMPAC in both 2014 and 2016. Despite growing tensions in the South China Sea and concerns about Chinese military transparency, the Obama administration included the People’s Liberation Army Navy (PLAN) in an effort to promote professional military dialogue and reduce the risk of miscalculation. China sent surface combatants, auxiliary vessels, and observers to participate in non-combat aspects of the exercise. This inclusion was reversed in 2018 following the continued militarization of artificial features in the South China Sea, but the precedent remains: even states that do not share U.S. values or alliance structures have participated in RIMPAC under constrained formats.

Similarly, RIMPAC has welcomed non-allied or non-aligned states such as Vietnam, India, and Brunei, each of which participated in observer or limited operational capacities. These arrangements allowed for diplomatic inclusivity without compromising the exercise’s core focus on interoperability and security cooperation. India was first invited as an observer in the early 2000s before gradually expanding its participation, culminating in the deployment of naval assets by the 2010s. This incremental approach demonstrates RIMPAC’s capacity to accommodate partners with unique diplomatic statuses or sensitivities.

The American Institute in Taiwan (AIT), established under the Taiwan Relations Act as the vehicle for unofficial U.S.-Taiwan relations, could serve as the conduit for managing Taiwan’s RIMPAC participation. AIT-coordinated representation would allow the United States to maintain consistency with its One China policy while exercising its commitment to Taiwan’s self-defense.

Managing PRC Backlash

Inevitably, Beijing would likely respond harshly to Taiwan’s inclusion in RIMPAC, as it has to other perceived infringements on its sovereignty claims. Large-scale military drills, economic sanctions, diplomatic condemnation, and cyber operations are all part of the PRC’s well-established retaliation playbook. Yet the United States and its partners must resist the temptation to let their Taiwan policy be dictated by fears of PRC outrage. This reactive posture grants Beijing a de facto veto over democratic decision-making and emboldens further coercion.

China has escalated its pressure campaign on Taiwan even in the absence of provocations. Since the election of Democratic Progressive Party (DPP) President Tsai Ing-wen in 2016, Beijing has employed what Richard Bush calls “coercion without violence,” a deliberate campaign to wear down Taiwan psychologically, politically, and economically without firing a shot.3 This has included near-daily air and naval incursions into Taiwan’s air defense identification zone (ADIZ), cyberattacks on government agencies, diplomatic isolation, and targeted disinformation campaigns.

These actions have continued even as Taiwan’s leadership has treaded cautiously. President Tsai’s tenure was marked by efforts to maintain the cross-Strait status quo and avoid unilateral declarations of independence. Her successor, President Lai Ching-te, has pledged to do the same, calling for “dialogue instead of confrontation” in his 2024 inauguration address. Nevertheless, Beijing has continued to characterize Lai as a “separatist” and launched punitive military exercises following both his inauguration and Taiwan’s National Day celebrations.

This pattern reveals a key truth: Beijing’s escalatory behavior is not a response to specific actions by Taipei or Washington, but part of a long-term strategy to bring Taiwan under PRC control. As such, restraint has not yielded peace; resolve may. Integrating Taiwan into multinational military exercises like RIMPAC would impose reputational and strategic costs on Beijing’s aggression by signaling that Taiwan’s security is a shared interest among responsible stakeholders in the Indo-Pacific.

Conclusion

Ultimately, deterrence fails when adversaries perceive inaction as weakness. Taiwan’s participation in multinational exercises is not merely symbolic. It is a necessary step to ensure that coercion is met with collective resolve. The message to Beijing must be unmistakable: the democratic world will not stand by while one of its own is bullied into submission.

It is time for the United States and its Indo-Pacific allies to move from passive deterrence to active deterrence. The inclusion of Taiwan in RIMPAC would send an unmistakable message to Beijing: any aggression against Taiwan risks triggering a multilateral response from a network of regional powers united by shared values and interests. Including Taiwan in RIMPAC would fulfill the spirit of the Taiwan Relations Act, enhance deterrence, and stand as a visible affirmation of America’s commitment to a free and open Indo-Pacific.

Why the U.S. Should Support South Korea’s Naval Expansion

By Ju Hyung Kim

When people think about the U.S.-ROK alliance, they often envision the Korean Peninsula: joint ground drills, combined air exercises, and the perennial challenge of deterring a North Korean invasion. But the next chapter of this alliance is unfolding at sea. With the U.S. Navy stretched across multiple theaters—from the Mediterranean to the South China Sea—South Korea’s maritime ambitions are no longer a peripheral concern. They are a strategic asset.

South Korea is undertaking a deliberate and ambitious transformation of its navy into a blue water force capable of regional power projection. This evolution is not simply about prestige or symbolism. It is a calculated move rooted in geostrategic necessity. As tensions rise in the Taiwan Strait and Chinese naval power expands across the first and second island chains, Washington should see Seoul’s naval modernization not as redundant or overlapping, but as a critical force multiplier.

This is especially relevant in the Yellow Sea, where a better-integrated U.S.-ROK naval posture could significantly enhance sea denial capabilities South Korea’s geographic proximity to China’s northern coastline presents a strategic opportunity to constrain the PLA Navy’s North Sea Fleet, which is headquartered in Qingdao and tasked with defending China’s most vulnerable maritime approaches. By jointly developing anti-access/area-denial (A2/AD) strategies focused on the Yellow Sea, the alliance could effectively impose strategic costs on China’s northern naval operations and blunt its access to the first island chain.

The Rise of South Korea’s Blue-Water Navy

The Republic of Korea Navy (ROKN) has traditionally played a coastal defense role focused on deterring North Korean provocations in the Yellow Sea and the Sea of Japan. But over the past two decades, a combination of economic capability, strategic awareness, and domestic political will has pushed Seoul to rethink its naval posture.

The evolution began with the KDX series of destroyers—KDX-I, KDX-II, and the 10,000-ton KDX-III (Sejong Daewang-class guided-missile destroyers)—equipped with Aegis combat systems, long-range anti-air missiles, and sophisticated sensors. These ships have given the ROKN capabilities far beyond the littorals. More recently, the KDDX program—slated to deploy stealthier, AI-integrated destroyers by the early 2030s—signals an even greater leap in warfighting capability.

Beneath the surface, South Korea is producing the Jangbogo-III class submarines, featuring Air-Independent Propulsion (AIP), advanced sonar, and the ability to launch indigenous cruise missiles. These quiet, long-endurance platforms are designed for regional influence, extending beyond traditional deterrence roles.

Then there is the controversial CVX program, which remains stalled due to political debate and lack of budgetary support. Initially conceived as a 30,000-ton light aircraft carrier to deploy short take-off and vertical landing (STOVL) aircraft like the F-35B, CVX was intended to give Seoul the ability to project power far from its shores. Critics within Korea have questioned its cost and doctrinal utility, and recent administrations have deprioritized the project in favor of counter-North Korean capabilities. Still, the strategic rationale behind the program reflects Seoul’s growing maritime confidence and its long-term ambition to contribute more meaningfully to regional security.

Strategic Drivers of Naval Expansion

South Korea’s shift toward a maritime posture is driven by three primary strategic imperatives. First, North Korea’s expanding maritime threat has grown increasingly sophisticated. Pyongyang’s development of submarine-launched ballistic missiles (SLBMs), its recent experimentation with unmanned maritime strike systems, and its emphasis on asymmetric naval tactics all underscore the need for a robust undersea deterrent. A capable Republic of Korea Navy (ROKN) is essential not only for defending territorial waters, but also for denying North Korea sanctuary beneath the surface. It is worth noting that the Atlantic Council’s recent report, “A Rising Nuclear Double-Threat in East Asia: Insights from our Guardian Tiger I and II Tabletop Exercises,” demonstrates how a naval skirmish in the Yellow Sea between North and South Korea could plausibly escalate—by 2030—into a dual contingency, triggering simultaneous crises on the Korean Peninsula and in the Taiwan Strait.

This scenario underscores the critical importance of effective naval deterrence and denial capabilities against North Korean maritime threats. It also implies a wider operational logic: improved U.S.-ROK naval integration could serve not only to deter North Korea but also to enhance regional readiness for broader contingencies involving both China and Russia. As Russia’s Pacific Fleet increases its operational tempo in the Sea of Japan—particularly near Vladivostok, its key naval hub—a forward-deployed and interoperable ROK Navy can play a vital role in surveillance, anti-submarine warfare, and presence operations. Greater alliance coordination in these waters would enable the U.S. Navy to retain pressure on Russian forces without further stretching its already overtasked carrier and submarine assets.

Second, South Korea’s economic vulnerability via its sea lines of communication (SLOCs) compels a more active naval presence. As a global trading nation heavily dependent on maritime imports—particularly energy—South Korea is acutely exposed to regional disruptions in maritime routes. Any conflict in the South China Sea or Taiwan Strait would pose serious risks to these lifelines, and protecting them requires more than the reach of coast guard patrols.

Third, shifts in U.S. force posture are creating strategic space—and necessity—for capable allies to assume greater responsibilities. As the United States confronts the demands of great power competition and redistributes its naval resources, a strengthened and regionally integrated South Korean navy can help relieve pressure by taking on critical missions in Northeast Asia, thereby enabling U.S. forces to concentrate on high-end deterrence operations elsewhere.

Naval Power and the U.S.-ROK Alliance

Historically, maritime coordination has not been the centerpiece of the U.S.-ROK alliance. While Combined Forces Command (CFC) has focused primarily on land and air integration, naval cooperation has traditionally been limited to joint drills and port visits—though this has begun to evolve in recent years with increased trilateral and ASW cooperation. But this is beginning to change.

The U.S. Indo-Pacific Strategy explicitly calls for networked security architecture, encouraging allied navies to coordinate maritime domain awareness (MDA), logistics, ISR (Intelligence, Surveillance, Reconnaissance), and undersea capabilities. South Korea has begun participating more actively in multilateral exercises like RIMPAC and Pacific Vanguard. Trilateral maritime exercises with the U.S. and Japan have also become more routine, despite political sensitivities in Seoul. However, these efforts remain fragmented and largely ad hoc, lacking the continuity and command structure necessary for sustained strategic impact. As the alliance faces increasingly complex, multi-domain maritime challenges—ranging from North Korean subsurface threats to regional contingencies involving China and Russia—the case for deeper institutional coordination becomes compelling. One promising pathway is the establishment of a Combined Maritime Command: a mechanism that could integrate planning, synchronize task force deployments, and enable real-time information fusion.

Unlike the existing ground-focused Combined Forces Command, such a structure would reflect the evolving character of naval warfare and anchor maritime cooperation in a permanent, mission-ready framework. Additionally, both Washington and Seoul are exploring data sharing and co-development in AI-enabled maritime systems. Seoul’s defense sector, spearheaded by companies like Hanwha Ocean and LIG Nex1, has the technological foundation to contribute to next-generation maritime warfare, from unmanned surface vehicles (USVs) to AI-supported sonar systems.

Policy Recommendations for Washington

Supporting South Korea’s naval rise requires more than rhetorical endorsement; it demands a set of deliberate and concrete policy actions by Washington. First, the United States should identify opportunities for joint research and development as well as limited technology transfer in key areas such as undersea warfare, autonomous maritime systems, and AI-enhanced command and control. Co-developing these capabilities with a trusted ally like South Korea would not only bolster interoperability but also strengthen Seoul’s defense industrial base.

Second, Washington should work with Seoul to institutionalize robust maritime intelligence-sharing mechanisms. Drawing inspiration from frameworks like the Five Eyes, a Northeast Asian naval intelligence partnership could significantly enhance regional maritime domain awareness and sharpen tactical decision-making across allied navies.

Third, joint training and exercises should be expanded beyond the waters near the Korean Peninsula. South Korea should be regularly included in U.S.-led naval operations throughout the second island chain, including in the Philippine Sea, South China Sea, and broader Western Pacific. Such participation would normalize long-range ROKN deployments and allow the U.S. Navy to maintain presence across a wider expanse without overstretching its own assets.

Finally, the alliance should explore the creation of a combined maritime command structure that parallels the existing Combined Forces Command on land. Although politically sensitive—particularly in light of ongoing discussions around OPCON transfer—such a structure would better reflect the realities of modern maritime warfare and the shared regional burdens that come with it. More concretely, a Combined Maritime Command could offer a standing bilateral mechanism for coordinating patrol areas, real-time sensor fusion, and logistics prepositioning. It would also allow for joint operational planning in response to overlapping threats from North Korea, China, and Russia—threats which increasingly defy traditional geographic boundaries. A permanent command structure would facilitate the joint execution of distributed maritime operations (DMO) and enable more dynamic force employment (DFE) within the alliance, aligning with current U.S. Navy doctrinal trends. However, such an initiative would need to overcome several significant hurdles.

Domestically, South Korea’s evolving but cautious posture on OPCON transfer and joint command structures could stir political controversy, especially amid ongoing debates over military sovereignty. Bureaucratically, the absence of a tradition of joint maritime commands within South Korea’s naval doctrine would necessitate a paradigm shift in command culture and planning processes. Operationally, issues such as legal authorities, peacetime rules of engagement, and joint logistics would need to be ironed out. To navigate these complexities, a phased approach may be prudent—starting with joint maritime planning groups, mission-specific task forces, and gradually evolving toward a permanent Combined Maritime Command as trust, interoperability, and strategic alignment mature.

Why the U.S. Needs a Strong South Korean Navy

Critics may ask whether the U.S. really needs another blue-water ally when it already works closely with Japan and Australia. But the answer lies in geography, capability specialization, and political flexibility. Japan’s navy is world-class in terms of technology and training, fielding advanced destroyers, submarines, and even F-35B-capable carriers. Yet it remains politically constrained by constitutional limitations—most notably Article 9—and cautious public sentiment that continues to shape the scope of Japan’s overseas military activities. Even after the 2015 legislative reforms and revised U.S.-Japan defense guidelines, Tokyo’s ability to engage in high-intensity or preemptive operations remains narrowly defined and heavily restricted. Australia, meanwhile, boasts potent naval assets but is geographically removed from key Northeast Asian flashpoints. South Korea, by contrast, offers an increasingly capable and politically willing partner, situated at the frontline of regional hotspots: the Yellow Sea, the East China Sea, and even the Taiwan Strait. Its navy is not only modernizing rapidly but is also unconstrained by many of the domestic limitations that hinder its allies.

Moreover, South Korea brings industrial capacity to the table. Its shipbuilding firms are already among the best globally. If the U.S. seeks to build a coalition-based maritime deterrent in the Indo-Pacific, Seoul is indispensable—not just as a consumer of U.S. systems, but as a producer of regionally relevant platforms.

At a time when the U.S. Navy is confronting widening capability gaps, the need for trusted, interoperable allies is more pressing than ever. Chronic delays in shipbuilding—exacerbated by industrial base constraints, workforce shortages, and budget uncertainty—have slowed the delivery of key platforms like the next-generation DDG(X) destroyers and the Columbia-class ballistic missile submarines. Meanwhile, maintenance backlogs have reduced the operational availability of existing surface combatants and submarines, straining fleet readiness. Carrier strike groups are being over-deployed to meet simultaneous demands in the Middle East, Europe, and the Indo-Pacific, often without sufficient dwell time, degrading both materiel and personnel endurance. Amphibious readiness is also under pressure, with debate continuing over the future of the LPD and LHA programs. In this environment, having a capable ally like South Korea—with Aegis-equipped destroyers, modern submarines, and ambitions for its own light aircraft carrier—is not a luxury or symbolic gesture. It is a strategic necessity. Seoul’s platforms are increasingly interoperable with U.S. systems, and their regional positioning allows the ROK Navy to help secure key maritime corridors and reinforce deterrence at precisely the time and place where U.S. naval bandwidth is most strained.

Conclusion: A Maritime Alliance for the Indo-Pacific Era

The U.S.-ROK alliance was forged in ground combat but will be tested in maritime competition. As the Indo-Pacific becomes the primary arena of strategic contestation in the 21st century, navies—not just armies—will shape deterrence outcomes.

Washington must therefore adapt its mindset. Supporting South Korea’s naval expansion is not about shifting the burden, but about co-creating a more resilient, integrated, and capable maritime network. Seoul is rising to meet the challenge. The U.S. should meet it alongside.

From undersea sensors to carrier decks, the next phase of alliance credibility will be forged at sea. It is time to set sail together.
