Conduct Legal Preparation of the Battlespace

Notes to the New CNO Series

By James Kraska

The U.S. Navy must rebuild its capacity to shape and influence international maritime law. Since the first Code of Naval Warfare was published at the U.S. Naval War College in 1900 through the negotiations of the Law of the Sea Convention in the 1970s, the U.S. Navy was a thought leader in establishing and upholding the global rules of the game, producing influential scholarship, participating in international meetings alongside the Department of State, and engaging with counterparts around the world. In 1979, the United States launched the Freedom of Navigation program to ensure unimpeded global access to the world’s oceans.

These efforts have diminished greatly as both the aptitude or expertise of naval officers to articulate a vision for the legal order of the oceans and the bandwidth of the Navy to influence maritime law have declined in recent decades. The number of experts has dwindled from formerly dozens throughout the Navy and the U.S. government to a handful today. The reasons for this shortfall are manifold: U.S. hubris in thinking that the rules-based order of the oceans it shaped during the Cold War will continue as a matter of its own logic, failure to recognize and respond effectively to opposing views of maritime law from European states, developing countries and China, and since the Clinton Administration, deference to competing priorities like protection of the marine environment and climate change at the expense of naval and operational equities.

The consequences of ignoring naval and defense interests in maritime law are grave, as the rules for operating at sea during peacetime and armed conflict are shaped by other nations, officials, and scholars with different priorities. The Chief of Naval Operations has an opportunity to revitalize the Navy’s expertise and influence in international maritime law. First, mandate the law of the sea and the law of naval warfare are added to the core curriculum of the U.S. Naval War College, the Navy’s “home of thought.” In decades past, U.S. and international students received one week of instruction in all areas of international law, now it is three hours. Actively teaching maritime law throughout the force must be a priority.

Second, engage purposefully in the legal preparation of the battlespace by engaging in the numerous bilateral and multilateral negotiations on maritime law to ensure new rules do not restrain naval commanders in peace and war. The International Committee of the Red Cross, for example, which is heavily subsidized by the United States, is working to restrict the use of autonomous warships during armed conflict, the very same platforms envisioned for the future force.

Third, rebuild maritime law expertise and train the force in the law of the sea and the law of naval warfare. Much of our collective experience in international law is from the ground wars in Iraq and Afghanistan, not operations at sea. We should refocus on the laws that apply throughout the global commons – sea, air, and space – that surround our Homeland and connects us to allies in Asia and Europe.

The Imperative for Integrated Maritime Operations

Notes to the New CNO Series

By Steven Bancroft and Benjamin Van Horrick

The Amphibious Ready Group/Marine Expeditionary Unit (ARG/MEU) team serves as the cornerstone of America’s forward-deployed, rapid-response capability. The MEU’s ability to blend land, air, and sea power to project maritime force and respond to global crises gives the joint force an exquisite capability.

However, as the 21st century’s strategic environment becomes increasingly complex with peer competitors, the enemy’s advanced anti-access/area-denial capabilities, and the proliferation of long-range precision fires, the Navy and Marine Corps must embark on a new phase of naval integration. The CNO, in conjunction with the CMC, should provide guidance on how to enhance maritime lethality to transcend the traditional ARG/MEU construct, thereby forging an integrated naval force capable of securing contested littorals and responding to emergent threats. 

Adversaries are challenging U.S. dominance at sea with the rapid modernization of their naval, air, and missile forces. The proliferation of sophisticated sensors, cyber capabilities, and hypersonic weapons exposes isolated task forces or expeditionary units to new vulnerabilities. To maintain credible deterrence, the Navy and Marine Corps are moving toward complementary operational concepts: Distributed Maritime Operations and Expeditionary Advanced Base Operations. These service-level concepts demand seamless integration and rapid maneuver to mass effects across multiple domains. 

The primary aim of naval integration is to enhance maritime lethality—the ability to locate, identify, and neutralize adversary forces at sea and in the littorals. This requires effective use of limited assets. The Navy, Marine Corps, and Army are investing in long-range precision fires, such as the Naval Strike Missile and the Maritime Strike Tomahawk. Moreover, integrated training and joint wargaming are forging a culture of interoperability and mutual understanding.

While the ARG/MEU team remains a vital tool, its relatively small footprint and limited stand-off capabilities prove insufficient against modern threats. 21st-century naval integration requires a maritime network with access to various platforms, sensors, and weapons systems that enable distributed forces to operate in concert. For example, a Marine Corps unit operating from an expeditionary advanced base can cue maritime or joint fires, while Navy assets provide mutual support with air defense and logistics. 

A notable example of this evolving integration was the Task Force 76/3 (TF-76/3) experiment, a combined Navy-Marine Corps formation designed to enhance operational synergy in the Indo-Pacific. TF-76/3 merged the capabilities of Expeditionary Strike Group SEVEN/Commander, Task Force 76 with the rapid response expertise of 3d Marine Expeditionary Brigade. Deploying as a single, integrated naval task force, TF-76/3 demonstrates how integrated command structures can enhance responsiveness and lethality. This synergy was enabled by advancements in command, control, communications, computers, cyber, intelligence, surveillance, and reconnaissance. 

Beyond the ARG/MEU team, 21st-century naval integration is more than a technological or organizational shift — it is an operational imperative. Combining the agility and expeditionary mindset of the Marine Corps with the firepower and reach of the Navy into a single, lower-level command, the naval service can build a more lethal, resilient, agile maritime force. This integrated approach—exemplified by formations such as TF-76/3, TF 61/2, and TF-51/5—ensures that U.S. naval power projection and dominance remain ready to meet the demands of the modern era.

Start Building Small Warships

Notes to the New CNO Series

By Shelley Gallup and Ben DiDonato

In past wars, small and well-armed ships have been a necessary complement to the large, multipurpose ships that dominate today’s U.S. Navy. China understands this and utilizes a full range of maritime capabilities to outmaneuver us. These ships can easily overwhelm the navies of smaller nations, like the Philippines, creating an unsustainable demand for support from our large ships, which are often disproportionate to the task at hand.

Our submarine and naval aviation forces are the best in the world, but our surface fleet is facing serious challenges. We do not have nearly enough destroyers to provide deterrence in the Pacific and other areas of the world. A recent CIMSEC article outlines the global growth of China’s dual naval and maritime militia forces, who are creating new demand signals for U.S. naval presence. We must begin to rethink end strength because numbers have a quality all their own. The LCS cannot take up the slack, and the Constellation class will take too long to build and there will be too few of them.

We also lack the logistics support needed for sustained operations and the tyranny of distance is very real. The answer is not to build more large logistics vessels, which will require escorts we do not have, but to reinvent what logistics means in this modern age, where range and endurance are ever more meaningful. Future warships can eliminate much of this problem through longer endurance and the ability to refuel at almost any civilian port to minimize the need for resupply. Small warships can also provide unique personnel logistics support by carrying Marines into harm’s way.

While AI and autonomy are advancing, these technologies are not yet suitable for many forms of deterrence and warfighting without human oversight. They are in a co-evolutionary period with crewed vessels, so the best path forward is to build manned ships on the AI and autonomy technologies being developed for USVs. This will dramatically reduce crew requirements and let us build a better understanding of these technologies for future applications.

To solve this problem, we should build smaller, well-armed, and lightly manned warships that can sustain persistent operations. Our proposed lightly manned warship design – LMACC – will help solve this problem by bringing in smaller U.S. shipyards to increase competition and capacity. The Lightly Manned Automated Combat Capability is a program at the Naval Postgraduate School. CONOPS have been written and are the subject of technical reports. It has produced theses, journal articles, fundamental and applied research, and an operationally-validated warship design that can be built in large quantities for less than $200 million per platform, today. The design includes the remedies described above, can support USMC littoral operations, and provides affordable capacity for missions like countering the cartels.

The crew of approximately 25 provide the decision making necessary for combat and deterrence. They are intended to work with the larger unmanned surface vessels in a 5G cloud-based infrastructure independent of satellite data or GPS positioning. These innovations are currently being tested and further refined at NPS.

LMACC will serve a critical function in developing future leaders. In today’s destroyer-centric surface fleet, platform command opportunities are only available after more than a decade of service. LMACC is intended as an O-3 command, affording naval officers an opportunity to command earlier in their careers and develop critical leadership skills, including initiative, adaptability, risk taking, and tactical acumen. Autonomous systems will become increasingly important, but cultivating warrior skillsets early will always be central to victory.

Small warships have a long history in the U.S. Navy and are poised to offer an evolutionary leap in capability. Small, highly automated, lightly crewed, blue-water warships will help offset the capabilities of competing fleets and ensure enduring maritime superiority for the U.S. Navy. It is time to build a prototype of the LMACC and its flotilla of innovations.

Dr. Shelley Gallup is a retired surface warfare officer. As an Associate Research Professor at the Naval Postgraduate School, Dr. Gallup has spent 25 years assisting the Navy in developing large-scale experiments at sea. His current work includes research in human-machine partnerships, the role of emergence in combat at sea, and leads the small warship LMACC project at NPS. He can be contacted at spgallup@nps.edu.

Ben DiDonato is a volunteer member of the LMACC team. He is responsible for LMACC’s armament and most engineering work. He has provided systems and mechanical engineering support to organizations across the defense industry from the U.S. Army Communications-Electronics Research, Development and Engineering Center (CERDEC) to Lockheed Martin Missiles and Fire Control, working on projects for all branches of the armed forces. He currently serves as vice president of technology for Expanse Laboratories Corporation, a startup developing novel physical encryption technology. He can be contacted at benjamin.didonato@nps.edu.

The Indian Ocean: An Opportunity to Strengthen Alliances and Deter China

Notes to the New CNO Series

By Captain Renato Scarfi, (Italian Navy, Ret.) and Captain Gian Carlo Poddighe (Italian Navy, Ret.)

Today, the new global order imposes a different vision of alliances. On the Western side, we are experiencing a temporary crisis of the values of transatlantic ties due to the political winds swaying, typical of democratic systems. But the idea of having achieved the conditions for an irreversible peace has unfortunately faded in the face of entrenched rivalries and strongly divisive attitudes. In this context, to be effective in the new world order, alliances must be global as a demonstration of shared will to achieve common well-being and prosperity. The naval instrument is a powerful tool for manifesting shared will and projecting influence, and the theater where this will be most effective is the Indo-Pacific. The main competition will take place in those waters, and marks an opportunity for the U.S. Navy to strengthen its naval cooperation with Europe.

A Western presence in the Indo-Pacific will be essential for our well-being and will be the true key to commercial and energy survival, particularly for the southern European countries. They are strategically vital for the balance of the Euro-Mediterranean region and to counter the growing Chinese influence on African territory. It will also be critical for containing the increasing Chinese maritime presence and claims in the Persian Gulf, the Red Sea, and North Africa, which currently sees the development of numerous maritime initiatives concentrated along those coasts, up to the Atlantic coasts of Morocco.

In this context, the Indian Ocean holds strategic importance, being both the key to maintaining freedom of navigation and trade to and from the Far East, as well as the route along which energy travels and investments develop. Maritime presence in the Indian Ocean is therefore not a possibility but an obligation, which should see a convergence of interest from NATO European countries. This should include cooperation with India, a democratic country that has historical tensions with China.

The U.S. Navy can help serve as a catalyst for this kind of naval presence. A permanent European naval presence in the Indian Ocean should be of extreme interest to the U.S. Navy, which could free up U.S. naval forces to better focus on the Pacific, in conjunction with Japan, South Korea, Australia and other allies. Equipped with aircraft carriers and capable of projecting power, European countries could strive to establish a permanent presence in the Indian Ocean and serve as a deterrent against assertive rivals. The Italian Navy, besides a longstanding presence in the area, can add over 20 years of experience from the VRMTC (Virtual Regional Maritime Traffic Centre), a system that collects maritime domain awareness data for over half the Atlantic, the whole Persian Gulf, and even the Indian Ocean.

The U.S. Navy and its Pacific allies can promote cooperation with European navies in Indo-Pacific theater. It can mark a catalyst that mobilizes and focuses Western resources while improving burden sharing. This initiative will strengthen our friendship and naval cooperation, and will represent a key factor in strengthening deterrence.

Captain Renato Scarfi (Ret.) joined the Italian Naval Academy in 1977. As LTJG he attended the U.S. Navy Pilot Training Program in Pensacola and Corpus Christi where he gained the Navy Wings for multi-engine fixed wing aircraft and helicopters. After the Staff Officer Course in Leghorn (Italy) he served in the Defence General Staff, the Navy General Staff (Plans and Policy), the Joint Operation Headquarters (JOHQ) as Head of Crisis management section, and the Cabinet of the MOD as Senior Military Assistant of the Diplomatic Advisor of the Minister. He has two Master’s Degrees in International Relations and in Maritime Strategies and a Second Level Master Degree in International anti-terrorism. 

Captain Gian Carlo Poddighe (Ret.) is a former Italian Navy officer who has served in the Navy research center, in shipbuilding programs, and conducted cooperation activities with foreign navies in Italy and abroad. He has been a member of  commissions of international organizations (ONU, BID, CELAC, CAF, AEC/CSO). He is a magazine and newspaper columnist, in The Independent, Diario de las Americas, El Globo, G.d.I. and others.
