If the U.S. Navy can’t Repair Ships in Peacetime, how will it do so in War?

By Michael Hogan

Introduction

The Navy has well-documented issues with building warships. Less discussed, but equally important, are issues with repairing the ships it already has, which jeopardizes its ability to meet its own goal of sustaining a across all platforms. As the Navy focuses on preparing for a great power conflict potentially, the Navy needs to improve not just its peacetime ship repair capability but also expand its capacity to account for wartime repair requirements. While the issues facing the U.S. shipbuilding industry are complex, and it will take time to expand shipbuilding capacity for large combatants, the U.S. shipbuilding sector does have a robust capacity to build smaller vessels that can improve the U.S. Navy’s repair capabilities. In fact, there are 125 private U.S. shipyards that are capable of building small vessels needed for repair and salvage. The United States needs to prepare now for battle damage repair by investing in repair ships, and learning lessons from recent emergent repairs and the last major war it fought at sea.

Historical Precedent: World War II

A potential war with China will be fought mostly in the Pacific theater, which forces the United States into a major logistical challenge due to the tyranny of distance from the homeland. During the last great power naval conflict, the U.S. Navy learned the importance of battle damage repair for sustaining a distant fight. One important component of victory in the Pacific was the work of naval auxiliaries that supported combatants, generally organized in Service Squadrons. Initially equipped with just oilers and other logistics platforms to replenish warships, fleet commanders realized the importance of deploying repair assets, especially fleet and salvage tugs, with these service squadrons to provide at-sea capabilities for recovering damaged vessels.

Fleet tugs, often cited in historical accounts, were essential in rendering salvage services. These tugs towed damaged vessels to areas where repairs could be made, often preventing the permanent loss of ships. The absence of fleet tugs at the Battle of Midway likely foreclosed the fate of the precious aircraft carrier USS Yorktown, as the Navy had not yet fully grasped the vital importance of salvage tugs in saving battle-damaged ships. Similarly, the carrier USS Hornet, destroyer USS Porter, and cruiser USS Atlanta were lost largely due to inadequate salvage capabilities.

As the importance of tugs became clear during the war, they were used extensively throughout the Pacific campaign to save ships, allowing temporary repairs and enabling them to return home for more permanent fixes. The United States invested heavily in this capability during the war, building more than 200 tugs and over 40 rescue and salvage ships. Floating drydocks also played a crucial role, enabling the Navy to make the repairs necessary to restore ships to seaworthiness—even if only temporarily—so they could return to the United States for more extensive repairs. When ships could not be saved, salvage vessels stripped valuable repair parts, ensuring that forward-deployed ships had access to critical resources. The ability to recover damaged ships and clear sunken vessels from ports was vital to maintaining momentum in the American island-hopping campaign, extending the time that ships could remain on station.

Current State of the Salvage Fleet

Today, the U.S. Navy’s salvage fleet is far less robust than the one that was essential to winning the Pacific campaign. After the Cold War, the Navy dramatically downsized its auxiliary ship fleet, reducing the number of vessels from 113 in 1994 to 52 in 1997, including the decommissioning of nearly all tenders. Currently, Military Sealift Command (MSC) operates only three ocean-going tugs, two rescue and salvage ships, and two submarine tenders, with the newest of these vessels commissioned in the mid-1980s. In contrast, China, the pacing threat of the United States, has 30 tugs, 46 rescue and salvage ships, and 12 tenders between its navy and rescue and salvage bureau.

As analyst and retired naval officer Brent Sadler notes in U.S. Naval Power in the 21st Century, there are no large floating dry docks capable of repairing Ohio-class submarines and large surface combatants—despite their critical role in post-accident recovery, such as the repair of the USS San Francisco after its grounding in 2005. Floating drydocks provide a mobile repair capability, allowing significant repairs to be conducted in locations where permanent infrastructure does not exist, such as forward deployed bases during a regional conflict. This results in the US Navy either needing to bring the damaged vessel back to one of the homeland drydocks, which are already at capacity with modernization and maintenance, or lease a floating drydock from private industry. The Navy must also rely on chartered commercial heavy-lift ships to move damaged vessels, such as when the USS Cole had to be transported to Pascagoula for repairs after the 2000 terrorist bombing.

Recent Incidents and Issues

The U.S. Navy has not faced significant battle damage repairs since the 2000 terrorist bombing of USS Cole, the closest a U.S. Navy ship has come to combat damage in the last 30 years. Nevertheless, repair issues during recent forward-deployed collisions, allisions, and groundings mark a good approximation of what to expect, albeit on a smaller scale. Minor repairs following a collision, such as USS Jacksonville in 2013, can be made pier side, even in foreign ports, with the assistance of a submarine tender. Although, as noted above, the tender capacity has been drastically reduced in recent years. With public shipyards operating near capacity, however, more significant collision repairs require trade-offs.

Following two 2017 surface collisions in the Pacific, USS John McCain and USS Fitzgerald both required extensive repairs prior to their return to service. McCain was repaired in Yokosuka at Ship Repair Facility-Japan vice bringing it back to the U.S. for repairs. Fitzgerald, on the other hand, was contracted out to Huntington Ingalls Industries shipyard in Pascagoula, MS. Both ships required leasing a heavy lift transport to their repair destination, like Cole. The grounding of the USS Connecticut in 2021 offers a different trade-off. After colliding with a seamount, the submarine remained at Puget Sound Naval Shipyard from December 2021 to July 2023, until entering dry dock for her previously scheduled Extended Dry-docking Selected Restrictive Availability (EDSRA), where the repairs would be made. In this case, Connecticut was “lucky” that the incident occurred close to a scheduled maintenance period.

Even if the U.S. Navy added the recommended salvage tugs and floating drydocks, the navy’s shipyards are already stretched beyond their limits with planned modernization and maintenance. For example, faced a prolonged and costly repair timeline when the submarine’s fiscal year (FY) 2016 overhaul was canceled to accommodate ballistic missile submarine and aircraft carrier maintenance, losing its dive certification in 2017. Only in early 2024 was a contract signed to begin the overhaul, nine years after its last deployment, with expected completion in 2029 at the cost of $1.17 billion. The loss of operational capability, crew experience, and the daily upkeep costs over almost 15 years could add up to be more detrimental than the price tag itself, especially when the fleet is already straining to meet operational demands.

At a time when Congress is focused on getting newly built submarines delivered promptly, the inability to use one that the U.S. Navy already owns is unacceptable. These types of delays will only become more commonplace in a conflict without expanding our salvage and repair capabilities.

Congress has shown that it is willing to address such shipyard issues, for example, allocating, but this is focused on producing new construction submarines for the U.S. Navy and the AUKUS agreement. The 2018 investment in the Shipyard Infrastructure Optimization Plan was important but it is over budget and behind schedule, and the chronic delay in ship repairs remains. In FY21 and 22, less than 40 percent of ships completed maintenance availabilities on time.

All these shortfalls come during planned, peacetime maintenance periods. If the U.S. Navy needs to make repairs to battle damage in a major conflict, they do not have the salvage capabilities to conduct repairs at sea or forward deployed, they do not have the industrial base to support the additional work, and they do not have the open shipyard space to put the damaged ships. To make U.S. ship repair shortcomings worse, China has more than 200 times more capacity for shipbuilding, including a large commercial capacity, that can likely be repurposed in time of conflict for repairs.

The Way Ahead

To address these deficiencies in repair and salvage capabilities, the U.S. Navy, Department of Defense, and Congress must learn from recent incidents and the lessons of World War II. First, the Navy should implement the recommendations from the recent Government Accountability Office (GAO) report on ship repair, such as “developing a ship industrial base strategy that aligns with the National Defense Industrial Strategy.” As part of this, the Navy needs to examine all emergent repairs spurred by modern incidents starting with USS Cole to identify gaps in planning and capabilities, and the root causes of delays. This should include where salvage and repair ships were needed and unavailable. Any needed infrastructure or platform investments, such as forward-deployed floating drydocks, should be forwarded to Congress for supplemental funding. Immediate investments in these capabilities will bolster the U.S. Navy’s ability to better perform peacetime maintenance while building capacity to absorb battle damage repair in future conflict.

Second, Congress should pass the bipartisan SHIPS for America Act, providing 10 years of funding to boost the commercial shipbuilding industry and the merchant marine. This will help to provide more shipbuilding and repair capability and capacity throughout the United States in the event of future conflicts, and train qualified personnel for the MSC that mans and operates the Navy’s repair and salvage fleet. The combination of short- and long-term investments will turn the tide on the U.S. Navy’s repair capabilities before ships are lost, while sustaining them for decades to come.

Third, the Department of Defense needs to recognize ship repair as equal to shipbuilding when prioritizing funding. Ship repair is a subset of some of the Secretary of Defense’s 17 FY26 budget priorities, and a priority of the CNO’s Navigation Plan. Repairing ships already in Navy service reduces the effect of problems in shipbuilding. Finding ways to repair ships quicker increases public shipyard capacity, but this alone is not enough. The Department of Defense needs to create its own surge capability for the desired increase in naval fleet size and invest in private industry surge capability that can be optioned in case of added battle damage repair. Allocating the requisite funding to improve capacity and capability now will better prepare the U.S. Navy for great power conflict.

Conclusion

The U.S. Navy faces a growing challenge in maintaining a combat-ready fleet. It was lucky when a recent collision between the USS Harry S Truman and a merchant vessel outside the Suez Canal required only minor repairs before the carrier could return to sea. If the Navy is to meet the demands of a major conflict, it must prioritize not only shipbuilding but also ship repair and salvage capabilities. The lessons of the past are clear—effective battle damage repair and salvage can mean the difference between victory and defeat. This means not just adding to the capacity to repair current ships but also building capacity for the larger fleet of the future and creating a surge capacity for times of conflict. By addressing these gaps now, the United States can ensure the Navy is prepared for whatever the future holds.

War Without Surprises: Education for Command in the PLA Navy

This republication is adapted from “War without Surprises—Education for Command in the People’s Liberation Army Navy,” published by the Naval War College Review of the U.S. Naval War College. It is republished with permission.

By Ryan D. Martinson

Most analyses of Pacific scenarios have focused on the quantities and capabilities of the platforms that the PLAN might employ to achieve its campaign objectives. To date, there are very few studies about the people who would operate this hard­ware or the officers who would command them. This article seeks to contribute to this neglected area of China security studies. Specifically, it examines the role of professional military education (PME) in preparing PLAN officers to com­mand forces in combat.

PME is a key part of military officers’ preparation for command. It teaches them to look beyond the narrow confines of individual platforms or units and to consider the political, operational, and strategic issues relevant to joint action. Perhaps most famously, the USN officers who led the campaign to defeat Japan in the Pacific War—Chester W. Nimitz, William Halsey Jr., Raymond A. Spruance, Richmond K. Turner, and others—leaned heavily on knowledge and experience gained while students at the U.S. Naval War College. The education they received in Newport in the 1920s and 1930s prepared them for leadership by forcing them to grapple with the scenarios, situations, and challenges they later faced in a war with Japan. Repeated simulation of that conflict through strategic- and tactical-level wargames was a core component of their educational experience.

In the PLAN, midcareer officers on the path to senior command are required to complete two separate certificate courses at the Naval Command College (海军指挥学院) in Nanjing. These programs respectively prepare officers to command forces at two different levels of warfare: the high-tactical level (i.e., combined arms) and the campaign level (i.e., operational). In the event of a conflict, the success of China’s maritime operations will depend heavily on its naval officers’ leadership acumen. Thus, the type and quality of instruction they received at the Naval Command College will have a direct bearing on China’s wartime performance.

Education for Command

Located in the city of Nanjing, the PLAN’s Naval Command College is the center of education for midcareer Chinese naval officers. The college provides two main courses of study: (1) an intermediate course, Naval Combined Arms Com­mand (海军合同指挥), for captains, and (2) a senior course, Naval Campaign Command (海军战役指挥), for senior captains. The intermediate course lasts ten months, the senior course five months. Officially, both courses are required for officers on the path to flag rank, but it is unclear to what extent this require­ment is enforced. Neither course confers a graduate degree, though the college does also offer separate MA and PhD programs for qualified officers.

Only PLAN officers may enroll in the two courses. While the college does ma­triculate foreign students, they take a separate course of study. This allows PLAN students to be fully immersed in the best available (i.e., classified) information about their own military and the militaries of potential adversaries. Officers from other PLA services do participate in short-term learning opportunities at the col­lege and may apply to its graduate-degree programs, but none appear to enroll in the naval command courses. PLAN officers who promote to flag rank will later attend a third educational course on joint operational command at the National Defense University in Beijing.

Intermediate Course

As the course title implies, students enrolled in the intermediate course focus their studies on the theory and practice of combined-arms naval warfare—that is, the employment of forces from two or more service arms (surface, submarine, air, marines, and coastal defense) to achieve operational objectives on or from the sea. The curriculum is intended to prepare them to serve in leadership posi­tions at the high tactical level, such as commanding an operation to degrade or destroy an enemy aircraft carrier strike group. Since 2012, the college has required intermediate students to study topics in military and national strategy, in recognition that naval officers—perhaps more so than the officers of any other service—must be prepared to make tactical decisions that could have major stra­tegic consequences. To that end, students take courses such as Strategic Guidance for Maritime Military Operations, taught by Professor Huang Chunyu. While in Nanjing, students are almost certainly required to demonstrate proficiency in Chinese Communist Party dogma, especially as reflected in the speeches and writings of party “core” and CMC chairman Xi Jinping.

Student learning objectives are met through several different pedagogical approaches. Courses had long been taught using a traditional lecture style. However, in 2014 the college began exploring the use of the “flipped classroom” methodology to increase student engagement. This approach requires students to come to class already prepared to discuss the content of outside readings. It is unclear what portion of courses are taught using this method today. Students are also assigned research projects relevant to real-world concerns and germane to their individual experience and expertise. One past project for intermediate students involved research on the best tactics for Chinese ship formations to “raid” (突击) enemy task forces.

Classroom lectures are supplemented by presentations from outside experts, both military and civilian, akin to the U.S. Naval War College’s Lectures of Op­portunity. Operational commanders are invited to visit the college to share their firsthand experience from the fleet. For example, in the summer of 2022, soon after completing a major training mission aboard a nuclear-powered sub­marine, the deputy chief of staff of a PLAN submarine base, Wang Jun (王俊), came to the college to present a lecture on the PLAN’s operational employment of submarines.

In recent years, the college has created programs to foster online collaboration with students and instructors from other Chinese PME institutions. The goal is to bolster student familiarity and awareness of the equipment and weapons (装备性能), operational characteristics (作战特点), and operational methods (战法运用) of other services. This represents an effort to cultivate naval officers capable of serving in joint leadership positions—an imperative in the postreform PLA.

Aside from traditional academic course work, students engage in “practical learning activities” (实践性教学活动) while at the college. Since students can­not practice their new knowledge and skills through the movements of real ships, submarines, missile batteries, and aircraft, they use simulation tools. These are made available in the college’s wargaming center, the Naval Combat Laboratory (海战实验室中心). Students use the laboratory’s facilities to conduct scenario development; one-sided simulations; two-sided, opposition-force simulations (双方对抗); and joint exercises. For example, students might play out a scenario in which Red (i.e., Chinese) surface, air, submarine, and coastal-defense forces must provide “cover” (掩护) for a Red submarine as it tries to break through a Blue (enemy) blockade. Students and instructors also participate in major training and analytic games hosted by the Naval Combat Laboratory. All these simulation activities culminate in a capstone graduation wargame, discussed in detail in the next section.

For some students, these practical learning experiences take place beyond the college walls. In 2012, the college created a program to include students in fleet opposition-force exercises by “embedding” (嵌入) them in Red or Blue com­mand posts. The intention was to provide students with opportunities to “digest the theoretical knowledge” (消化理论知识) they accumulated in the classroom, “master use of operational methods” (掌握战法运用), and “gain familiarity with the real situation at the fleet” (熟悉部队实际). This initiative reflected a deliber­ate effort by the college to “get closer to the fleet and focus on real combat” (向部队靠拢, 向实战聚焦). Students participate in these exercises under the guid­ance of college instructors.

After completing the intermediate course, officers are eligible for deputy divi­sion leader (副师职) command. A surface warfare officer, for example, could be assigned to serve as the deputy commander of a destroyer flotilla (副支队长). From that position, they may, for example, deploy as the commander of a PLAN surface task force operating in contested areas of the East China Sea, with ample opportunity to apply the skills and knowledge learned in Nanjing.

Senior Course

Beginning in September, the senior course lasts five months. While in Nanjing, the officers study “the theory of joint operational command” (联合作战指挥理论), “familiarize themselves with the employment of forces from other services and service arms” (熟悉军兵种运用), “research joint campaigns and operational methods” (研究联合战役战法), and study historical naval campaigns. Stu­dents likely master current PLA campaign doctrine and strategic guidelines as pro­mulgated by the CMC, in preparation for their future roles. Instructors assign senior students research proj­ects relevant to their warfare foci, such as best approaches to prevailing in a contest over a disputed island. Like students in the intermediate course, senior students some­times are sent out to the fleet to embed in command posts, both Red and Blue, during opposition-force exercises. Given the new emphasis on jointness, students have the option of visiting other PME institutions to learn how different services operate. As in the intermediate course, simulation is a major part of the curriculum, with a focus on the operational or campaign level of war. After graduation, senior students are eligible to serve in billets with the grade of division leader (正师职). A graduate could, for example, command a destroyer flotilla, or serve as the deputy commander of a naval base.

The Capstone Graduation Exercise

In January or February each year, students from the intermediate and senior command courses participate in a campaign-level capstone wargame formally called the “graduation joint exercise” (学员毕业联合演习). The exercise, code-named SEA PLAN (筹海), occurs over seven to ten days and involves about two hundred students plus approximately one hundred outside observers and partici­pants from other PLAN units, the theater commands, and other PLA services.

Though called “exercises” (演习) or “drills” (演练), these events meet the basic definition of a wargame (兵棋推演) as understood in both China and the West: namely, a simulated conflict involving opposing sides, who make decisions on the basis of established rules. Participants are divided into Red and Blue—and often Green (i.e., third party)—teams. Each side comprises different cells representing different levels of leadership in the chain of the command. The teams are given objectives and develop plans to achieve them. The conflict progresses on the basis of alternating decisions made by the warring sides, expert judgments about the outcomes of these decisions, external circumstances controlled by game direc­tors, and, of course, chance.

The annual SEA PLAN exercise is a major event at the college. The college’s president is heavily involved in the game; he or the political commissar serves as the overall exercise director (总导演). The head of the college’s Training Department and the college’s vice president serve as his deputies (副总导演). Executive game directors are senior members of the college faculty. The game di­rector (导演组组长) for the 2021 SEA PLAN exercise, for example, was Ji Shixun (计世勋), head of the college’s Operational Command Department.

The capstone exercise is also a major event for the PLAN and the rest of the military. Personnel from the theater commands, other services, and PLAN Headquarters commonly send observers to the games. SEA PLAN is considered a model for a campaign-level “command opposition-force exercise” (指挥对抗演习). Therefore, training departments from across the fleet send personnel to watch, participate, and learn.

The SEA PLAN exercises are held in the college’s Naval Combat Laboratory. The laboratory is considered the PLAN’s most advanced facility for campaign and tactical-level wargaming. It has been designated a “key warfare laboratory” (全军重点实验室), one of the few within the Chinese military. It is the navy’s only warfare lab (作战实验室) that does campaign and tactical simulation train­ing, operational-methods research, and testing and validation of operation plans. One PLA Daily article described the laboratory as “famous across the whole mili­tary” (全军著名的). Housed in “a mysterious structure” (一栋神秘建筑) next to the main teaching building, it is rarely photographed, either inside or outside.

Students from both the intermediate and senior courses participate in the Red cells, with senior course students serving as campaign-level leaders. Students make the bulk of the decisions, applying the knowledge they learned in the class­room. College faculty members grade them on their performance.

While some students are assigned to the Blue and Green teams, many of these positions are filled by college faculty members—specifically, personnel from the college’s Blue Team Center (蓝军中心). Created in August 2012, the Blue Team Center serves as a think tank comprising thirty-plus faculty experts who engage in intensive study of the strategies, doctrines, tactics, operational concepts, orga­nization, and leadership culture of real-world potential adversaries. Members of the college’s Blue Team Center are much sought after by the fleet for their exper­tise and frequently travel to support fleet exercises, providing advice to exercise organizers and playing members of Blue or Green command posts.

SEA PLAN organizers craft games that are intended to be realistic. Scenarios are based on real-world concerns and real-world adversaries or potential adversaries. Students who play Red are playing China. Participants who play Blue or Green are playing Taiwan, Japan, Vietnam, the Philippines, or the United States, de­pending on the scenario. For Red, the game’s command interface is based on the Integrated Command Platform (ICP) actually used by the PLA since late 2008. The capabilities of Red forces match existing Chinese capabilities. The same goes for Blue and Green. Students are required to give mock press conferences to ex­plain and defend their side’s actions, as military officers might be required to do in an actual conflict. Students apply real doctrinal concepts, such as the “Three Warfares” (legal warfare, psychological warfare, and public opinion warfare), to their campaign execution.

Red’s command levels are based on existing command-and-control structures, which have changed in recent years. The designers of SEA PLAN–2016 eliminated fleet command-post cells, replacing them with joint maritime operations com­mand posts, which, as in the real world, had the authority to command all PLA forces operating over water. According to participants, the new command-and-control arrangements increased the speed and efficiency of force employment, though commanders apparently had a difficult time processing the larger amount of information they received. To make these cells more realistic, the college invited outside experts to play other-service members in the joint cell. For the 2021 capstone exercise, for example, the college invited nearly a hundred outside personnel from the PLAGF, PLAAF, PLARF, and PLA Strategic Support Force from an unnamed theater command (probably the Eastern Theater Command) to play in the game cells.

SEA PLAN scenarios echo real-world events and concerns. In the Xi Jinping era (2012 to present), several of the games have involved “gray zone” incidents that escalated to armed conflict. For example, the 2014 war-game scenario started with a collision between a Red coast guard cutter and a Blue warship, resulting in injuries to Red personnel. The incident quickly escalated to conflict. The 2016 game centered on Red’s defense of a large oil-and-gas-drilling platform pre­sumably placed in contested waters, a scenario identical to that which occurred between China and Vietnam from May to July 2014 in the South China Sea. In the 2017 game, Red installed an “ocean monitoring station” (海洋监测站) in a disputed area, leading to a forceful response from Blue, including “obstruction and sabotage” (阻挠和破坏). At the time, the PRC was planning to install such a station at Scarborough Shoal, though it ultimately chose not to. The 2021 game was a Taiwan conflict scenario, presumably reflecting the growing tensions over the status of the island nation.

Naturally, U.S. military intervention in the types of regional conflicts being wargamed is a major concern for the players, and the college often includes a Green cell to play the United States (for those games where the United States is not the opposing Blue force). Green forces intervene in the conflicts in a variety of ways: they employ electronic warfare to obstruct Red operations; invent legal­istic rationales for maintaining presence in the vicinity of the conflict, complicat­ing Red’s actions; and share intelligence on Red with their partners and allies. In the 2021 game, Blue (as the United States) directly intervened in a Taiwan crisis, leading to armed conflict with Red. The episode began with a battle of wills: Blue insisted on maintaining a humanitarian corridor by creating no-fly and no-sail zones (禁飞禁航区) adjacent to the island. It then dispatched aircraft to the scene to conduct electronic-warfare attacks “to isolate the battlefield” (战场阻隔), putting Red in “a very difficult spot” (防不胜防). Red employed ocean surveillance vessels and antisubmarine warfare air­craft—which dropped large numbers of sonobuoys—to track Blue submarines operating in the area. Game adjudicators judged these efforts to be successful, with one Blue submarine sunk, the victim of a torpedo fired by a Red surface combatant. Blue responded with “integrated air and sea strikes” (海空一体打击行动) with the support of unmanned aerial vehicles employing electronic-warfare tactics, sinking or damaging several Red ships. Ultimately, Red prevailed by leveraging what its campaign commander—Senior Captain Jiang Zhonglin (蒋忠林)—described as its “obvious joint strike advan­tages in the theater” (我作战海区联合打击优势明显).

Conclusion

Fifteen years after the end of World War II, the then-retired Chester Nimitz vis­ited the U.S. Naval War College, where he praised the institution for its valuable role in preparing naval officers like him for command in the Pacific. Perhaps with some exaggeration, he declared: “The war with Japan had been re-enacted in the game rooms here by so many people and in so many different ways that noth­ing that happened during the war was a surprise—absolutely nothing except the Kamikaze tactics toward the end of the war; we had not visualized those.” That is high praise—and similar to what may well be applied by PLAN admirals to the Naval Command College in the future.

As this article has shown, the college at Nanjing is almost entirely focused on preparing naval officers to serve command positions in the future mari­time conflicts that China is most likely to fight. Students participating in the intermediate-level course are dedicated to the study of combined-arms naval command, while officers in the senior course concentrate on naval campaign command. In recent years, course work on strategic-level issues has been in­troduced to ensure commanders are able to grasp the larger context of their actions, but the core purpose of learning is to cultivate naval officers who can make rapid and smart decisions about how best to employ Chinese naval assets to prevail in conflict at sea.

The PLAN Naval Command College’s focus on naval warfare is reflected in its full embrace of educational wargaming. Gaming is treated as a didactic tool for both the intermediate and senior courses. Students are expected to leverage the advanced facilities available at the college’s Naval Combat Laboratory—the PLAN’s most advanced facility for tactical- and campaign-level wargaming. Moreover, the heart of the college’s academic calendar is a seven-to-ten-day capstone wargame held each winter. The school’s senior leaders are directly involved in the game, a reflection of the importance attached to it. The college as­signs members of its Blue Team Center—the PLAN’s premier corps of experts on China’s future enemies—to join the Blue and Green cells. The scenarios are real­istic, and the capabilities, organization, and doctrines of Red, Blue, and Green are intended to reflect real life. The result appears to be a highly valuable educational experience for the participants. In the words of one recent student, Li Haichen (李海臣), the sense of “shock and reflection brought by this exercise will follow me throughout my career.”

In sum, the Naval Command College strives to provide midcareer officers with a full appreciation of the conflict scenarios China could face and the military problems with which PLAN officers must grapple to serve as effective wartime commanders at the high-tactical and operational levels of war. Therefore, gradu­ates should return to the fleet well versed on the PLAN’s best estimates of how the next maritime conflict might start, where it will take place, who will be involved, and what roles PLAN forces will be expected to play.

This preparation, of course, does not guarantee superior command perfor­mance in China’s next conflict. As the profiles of three recent graduates of the senior course suggest, students come to Nanjing very raw, with deep experience in a particular warfare community, often in a single unit or geographic area, but with little if any meaningful engagement with other warfare communities in the PLAN, let alone joint experience. It is difficult to imagine that a mere five months at the college can transform these students into effective campaign-level commanders. Moreover, despite some efforts by the college to teach students about the cultures, capabilities, and jargon of other services, it fundamentally remains an institution focused on naval education. This focus puts it at odds with the current PLA imperatives to cultivate officers prepared for joint command. Lastly, effective wartime leadership requires a number of other qualities that may not—perhaps cannot—be cultivated at the Naval Command College, owing to factors inherent in China’s Leninist system. These involve questions of character, individual empowerment, and independence of thought.

Nevertheless, the PLAN’s approach to midcareer officer education should prompt some reflection within U.S. PME institutions—above all, within the U.S. Naval War College. Do existing curricula strike the right balance between strategy and policy studies and the practice of modern naval warfare? Do all graduates depart the College with a solid understanding of the capabilities, doc­trines, and organization of the country’s most dangerous potential adversary? How much educational wargaming is needed to give naval officers ample oppor­tunity to apply the knowledge they gain in the classroom? Despite the tendency of USN leaders to glorify the achievements of the War College in the 1920s and 1930s, it is the PLAN—not the U.S. Navy—whose midcareer officer education more closely resembles the practices of that era. Has the College simply evolved a better approach, or might there be elements from the past worth resurrecting?

The Caribbean Sea: A Strategic Area with Many US Allies and Partners

By Wilder Alejandro Sánchez

Written by Wilder Alejandro Sanchez, The Southern Tide addresses maritime security issues throughout Latin America and the Caribbean. It discusses the challenges regional navies face including limited defense budgets, inter-state tensions, and transnational crimes. It also examines how these challenges influence current and future defense strategies, platform acquisitions, and relations with global powers.

In late March, the U.S. Navy cruiser USS Normandy (CG 60) and the Guyanese patrol vessel Shahoud carried out joint exercises in Guyana’s exclusive economic zone and international waters. Washington has many allies and partners across the Greater Caribbean, particularly among the region’s English-speaking nations. Despite having limited budgets and assets, the defense forces of the English-speaking Caribbean are training and increasing their capabilities to carry out missions, which aligns with US diplomatic and military objectives.

Ongoing Dialogue

The good news is that high-level interactions between the U.S. military and Caribbean militaries continue. U.S. Navy Admiral Alvin Holsey, the Commander of U.S. Southern Command (SOUTHCOM), traveled to Trinidad and Tobago last December to participate in the Caribbean Nations Security Conference (CANSEC) 2024.

In early January, U.S. Coast Guard Vice Admiral Nathan Moore, Commander of the Atlantic Area, visited Barbados and met with Barbados Defence Force Chief of Staff Brigadier Carlos Lovell. The two senior officers discussed further cooperation on common threats, including transnational organized crime and illegal, unregulated, and unreported (IUU) fishing. Subject Matter Experts from the U.S. military traveled to Jamaica in March and visited the Jamaica Defence Force’s Joint Information and Operations Centre.

More recently, Secretary of State Marco Rubio visited Guyana, Jamaica, and Suriname in late March. The tour was a chance to address Caribbean defense and security issues: during his stop in the Jamaican capital, Rubio also met with Trinidad and Tobago Prime Minister Stuart Young and discussed the bilateral security partnership and regional security issues.

Recent Acquisitions by Caribbean Forces

Improving Maritime Domain Awareness (MDA) remains a priority for Caribbean governments and their defense forces. Hence, regional naval forces acquire new surface and aerial assets for these missions. The Royal Bahamas Defence Force (RBDF) has led the way over the past decade via the Sandy Bottom Project, which enabled the acquisition of a fleet of different Damen-made surface vessels, including patrol vessels. The RBDF has also acquired a fleet of drones. Similarly, the Jamaica Defence Force (JDF) has acquired four offshore patrol vessels, also manufactured by Damen, for the JDF Coast Guard; the HMJS Norman Manley arrived in late 2023.

More recently, the Antigua & Barbuda Defence Force (ABDF) Coast Guard announced in late February the commissioning of a new speedboat for the fleet, hull number CG11-1 Swordfish. This acquisition demonstrates Saint John’s commitment to strengthening the ABDF and improving MDA. Suriname’s Navy is now operating the patrol vessel RSS Barracuda (P501), acquired through a lease-to-buy agreement with Damen Shipyard Group. The ship will have “a crucial role in the protection of the maritime area of ​​the country,” explained the Ministry of Defense. (Suriname’s official language is Dutch, not English, but I will mention it nonetheless).

Guyana deserves special attention. In late 2024, Guyana finally received the 115-foot Defiant patrol vessel GDFS Berbice, produced by the U.S. shipyard Metal Shark. Berbice is the new flagship of the Guyana Defence Force (GDF) Coast Guard and will support maritime operations. Given that Guyana has a border dispute with neighboring Venezuela over Guyana’s Essequibo region and oil-rich waters, acquiring new platforms for the GDF is a priority. In fact, in early March, the Venezuelan patrol vessel ABV Guaiqueiri PO-11 entered Guyana’s exclusive economic zone and harassed oil assets operating there. In a statement, the Guyanese government explained that, “The Venezuelan naval vessel communicated threateningly via radio communication that FPSO PROSPERITY was operating in Venezuela’s exclusive economic zone before continuing in a Southwestern direction towards other FPSOs, to which it delivered the same message.” The Venezuelan Ministry of Defense justified the operation, arguing it took place in contested waters.

The U.S. military and coast guard presence in the Caribbean

The U.S. military, particularly SOUTHCOM, its maritime component U.S. Fourth Fleet, and even U.S. Northern Command (with The Bahamas within its area of responsibility) continue to engage Washington’s English-speaking allies throughout the Caribbean. Engagement is not limited to meetings but also bilateral and multinational military training. For example, SOUTHCOM sponsors the annual exercise Tradewinds, specifically designed for the Caribbean – Trinidad and Tobago hosted Tradewinds 2024. Bilateral training occurs when U.S. warships visit the Caribbean. Passing exercises (PASSEX) are fairly common, case in point, at the time of this writing, in late March, the Normandy and the Shahoud carried out joint exercises, including PASSEX, “in international waters and the Guyana Exclusive Economic Zone to exercise communications and interoperability, and practice joint maneuvers,” according to the U.S. embassy in Guyana.

SOUTHCOM remains focused on Humanitarian Assistance/Disaster Relief (HADR) missions across the Caribbean – and the rest of Latin America. The U.S. hospital ship Comfort is often deployed. However, in recent years, the Spearhead-class expeditionary fast transport vessel USNS Burlington (T-EPF 10) has also traveled throughout the Caribbean to assist populations in need. HA/DR operations are already taking place this year.

The Lesser Antilles Medical Assistance Team (LAMAT) 2025, commenced on 24 February, during which U.S. military medical personnel will visit several Caribbean nations. While LAMAT 2025 does not involve vessels, the humanitarian exercise will provide invaluable medical services to the inhabitants of Saint Lucia, Saint Vincent and the Grenadines, Saint Kitts and Nevis, and Guyana. “All involved agree LAMAT’25 is a win-win scenario, benefiting both U.S. military personnel and partner nations. The mission enhances medical readiness and strengthens partnerships while improving healthcare infrastructure in underserved areas,” explained Air Forces Southern, the aerial component of SOUTHCOM.

The U.S. Navy deployed several assets over the past years throughout the Caribbean as regional countries were hit by deadly and destructive natural disasters, such as hurricanes, floods, and earthquakes. (In previous commentaries for CIMSEC, this author suggested that SOUTHCOM deserves a permanently assigned hospital ship.)

As for security operations, U.S. Navy warships, particularly destroyers and littoral combat ships (LCSs), and U.S. Coast Guard cutters regularly patrol the Caribbean Sea to interdict illicit maritime activities, particularly drug trafficking via vessels and the infamous narco-submarines. Recent platforms deployed to the Command’s area of responsibility include the LCS St. Louis and the Arleigh Burke-class guided-missile destroyer USS Thomas Hudner (DDG 116). The U.S. Coast Guard Cutter Valiant unloaded approximately 12,470 pounds (5,656 kilograms) of cocaine in early March at Coast Guard Base Miami Beach, worth an estimated $141.4 million. The contraband was seized thanks to six interdictions in the Caribbean Sea.

Finally, the Caribbean Sea is ideal for testing emerging technologies. At the time of writing, Operation Southern Spear is underway as the U.S. Navy is testing Uncrewed Surface Vessels (USVs). The objective is to test new systems to develop the future U.S. Navy’s hybrid fleet as part of the service’s Project 33. 

Discussion and Analysis

Some Greater Caribbean countries have governments that clash with U.S. diplomatic aims, namely Cuba, Nicaragua, and Venezuela. However, the region has many historical and trustworthy U.S. allies and partners. In a recent interview, Belize Defence Force commander Brigadier General Azariel Loria discussed training exercises with SOUTHCOM, including Special Operations Command South (SOCSOUTH) and the Louisiana National Guard via the State Partnership Program. “We are eager to continue joint training exercises focused on countering transnational threats, with the goal of incorporating tactical operations, humanitarian assistance missions, and specialized training on counterterrorism and disaster response,” he said. BG Loria added that the BDF “looks forward to more innovated ways to take our partnership to another level to improve coordination between our land, air, and maritime units.” In other words, the commanding officers of the English-speaking Caribbean defense forces see the U.S. armed forces (including the Coast Guard) as important allies and partners for training and operating together to combat crimes in air, land, and sea. This relationship must not be lost.

The issue of equipment availability and serviceability is an obvious problem within the region. The Caribbean Sea is a large body of water, and Caribbean countries are not one single unified island nation. Depending on the country, each nation can include countless islands, islets, cays and atolls, and a vast maritime territory. Hence, regional naval forces require a fleet of surface vessels and maritime patrol aircraft to properly monitor and command their maritime territory. Certainly, more vessels demand additional expenses like port infrastructure, fuel, ammo, and crew, among other financial considerations, meanwhile defense budgets across the Caribbean remain limited, hamstringing fleets across the Caribbean. However, the examples mentioned in this analysis- the Bahamas and Jamaica acquiring several ships and the more modest acquisitions of Guyana and Antigua & Barbuda- demonstrate civilian authorities’ commitment to assign more budgets for maritime procurement programs.

Unfortunately, the threats of illicit activities and challenges across the Caribbean will remain ever-present. The sea is the preferred corridor for drug trafficking, while IUU fishing and human and weapons smuggling are also constant challenges and threats. An ongoing concern is the crisis in Haiti, which is forcing Haitians to migrate, often via vessels. Moreover, piracy is making a comeback. Last year, there were reports that two Haitian criminal entities, 5 Seconds and Taliban gangs (no relation to the Afghan Taliban), captured the freighter Magalie at Port-au-Prince’s Varreux terminal district, stealing one-sixth of the cargo of rice and took the crewmembers hostage. The situation was resolved when the police stormed the ship. Even though the incident occurred while the ship was docked, the situation in Haiti has become so dire that it now affects maritime shipping.

For the Caribbean, cooperation is the correct answer. Given the threat environment in the Caribbean Sea and limited surface and aerial assets to patrol this vast body of water, strengthening military-to-military relations advances U.S. and Caribbean interests. A lack of sufficient patrol vessels operated by Caribbean coast guards does not mean a lack of willingness to combat maritime crimes. The U.S. government should provide more tools, including a bigger budget for SOUTHCOM. Armed with a bigger budget, SOUTHCOM can expand its low-cost/ high-impact engagements, benefiting all partners across the Caribbean region.
