Program Executive Office, Unmanned and Small Combatants is an acquisition organization within the United States Navy responsible for development, procurement, fielding, and sustainment of unmanned systems and small combatant platforms. It manages a portfolio that ranges from surface and subsurface unmanned vehicles to littoral combatant ships and small craft, interacting with shipbuilders, defense contractors, research institutions, and foreign partners. The office executes programs that support naval modernization priorities, technological innovation, and fleet readiness across multiple operational domains.

History

The office emerged from reorganizations following force-structure debates after the Cold War and lessons from the Gulf War (1990–1991), the Iraq War, and the Global War on Terrorism. Its antecedents include program offices that oversaw Littoral Combat Ship acquisition, unmanned aerial vehicle projects tied to Naval Air Systems Command, and small combatant initiatives influenced by the 2001 Quadrennial Defense Review and the 2010s Department of Defense acquisition reforms. Milestones include integration of autonomous systems after demonstrations at Fleet Week (United States) and collaborative tests with Office of Naval Research and Defense Advanced Research Projects Agency. Congressional oversight from committees such as the United States Senate Committee on Armed Services and appropriations debates in the United States House Committee on Appropriations shaped funding trajectories across the 2000s and 2010s.

Organization and Leadership

Leadership has typically been vested in a Senate-confirmed Program Executive Officer reporting through the Secretary of the Navy acquisition chain to the Under Secretary of Defense for Acquisition and Sustainment. The office structure comprises program managers for surface systems, subsurface vehicles, unmanned aircraft systems, and small combatants, collaborating with the Naval Sea Systems Command, Naval Air Systems Command, and Naval Facilities Engineering Systems Command. Cross-functional integration involves representatives from the Chief of Naval Operations staff, the Defense Innovation Unit, and the Joint Chiefs of Staff for requirements alignment. Advisory links extend to the National Academy of Sciences, defense industry executives from firms like General Dynamics, Lockheed Martin, Boeing, and Raytheon Technologies, and academic partners such as Massachusetts Institute of Technology and Naval Postgraduate School.

Mission and Responsibilities

The office’s mission encompasses acquisition lifecycle management for unmanned and small combatant platforms to deliver capability to fleet commanders like those in United States Pacific Fleet and United States Fleet Forces Command. Responsibilities include requirements translation from the Chief of Naval Operations and operational fleets, program formulation for Research, Development, Test and Evaluation, systems engineering with Space and Naval Warfare Systems Command (SPAWAR), live testing at facilities like Patuxent River Naval Air Station, and in-theater sustainment for commands such as United States Fifth Fleet. It also executes interoperability initiatives with North Atlantic Treaty Organization navies and coordinates cybersecurity standards with United States Cyber Command.

Major Programs and Projects

Portfolio examples include unmanned surface vehicles developed under concepts linked to the Littoral Combat Ship mission modules, medium- and large-unmanned undersea vehicles associated with programs influenced by Undersea Warfare doctrine, and small combatants like littoral-class corvettes evaluated alongside NATO partners such as Royal Navy and Marine Nationale. Other projects reference autonomous mine countermeasure efforts connected to anniversaries like the Battle of the Atlantic and counter-piracy operations in the Gulf of Aden. Development partnerships have produced demonstrators that participated in events like the RIMPAC exercises and technology insertions validated at Surface Navy Association conferences.

Acquisitions and Procurement Process

Acquisitions follow processes governed by statutes overseen by the Federal Acquisition Regulation regime and shaped by posture reviews such as the National Defense Strategy. The office employs contracting vehicles including Other Transaction Authorities influenced by precedents from Defense Innovation Unit Experimental engagements and uses competition among industry teams including Austal USA, Huntington Ingalls Industries, and system integrators. Program milestones map to Milestone Decision Authority approvals involving the Assistant Secretary of the Navy (Research, Development and Acquisition), with Test and Evaluation oversight from Director, Operational Test and Evaluation. Congressional reporting aligns with requirements from the Congressional Budget Office and hearings before the Senate Armed Services Committee.

International Cooperation and Partnerships

The office engages in bilateral and multilateral cooperation through foreign military sales coordinated with the Defense Security Cooperation Agency and interoperability programs with partners including Japan Maritime Self-Defense Force, Royal Australian Navy, Republic of Korea Navy, and Italian Navy. Collaborative research initiatives have connections with NATO agencies like the NATO Allied Maritime Command and multinational exercises such as Sea Breeze (exercise). Export control regimes including the International Traffic in Arms Regulations shape transferability, while partnership dialogues involve defense attachés from embassies and delegations to forums like the Security Cooperation Enterprise.

Challenges and Future Developments

Challenges include rapid technology pace exemplified by advances at DARPA and commercial firms such as SpaceX affecting autonomy and sensors, integration complexity across platforms tied to legacy fleets like Arleigh Burke-class destroyer systems, and budgeting constraints debated in Budget sequestration in the United States. Future developments point to increased use of artificial intelligence informed by research at Carnegie Mellon University and Stanford University, distributed lethality concepts debated in Strategic Studies Quarterly, and expanded cooperative programs with allies under initiatives like the AUKUS dialogue and expanded participation in multinational exercises such as CUTLASS FURY.
