Mentioned:LDOS Leidos
USS Theodore Roosevelt arrived at Yokosuka Naval Base in Japan on October 16, 2026, carrying Leidos' Seahawk unmanned surface vessel for the first operational deployment of a large unmanned vessel with a U.S. carrier strike group. Carrier Strike Group 9 comprises approximately 5,000 sailors and Marines preparing for the Keen Sword 2027 exercise involving 45,000 Japanese personnel and six allied partner nations.
What's happening
- USS Theodore Roosevelt (CVN 71) arrived at Yokosuka on October 16, 2026, marking the carrier's first visit to the base and deployment with Leidos' Seahawk autonomous trimaran.
- Seahawk is a composite trimaran displacing 147.3 tonnes with a 53,000-liter fuel capacity, equipped with Leidos Autonomous Vessel Architecture for collision avoidance and remote supervision.
- Carrier Strike Group 9 comprises approximately 5,000 sailors and Marines and will participate in Keen Sword 2027 exercise from October 19 to October 29, 2026.
- Keen Sword 2027 involves 45,000 Japanese personnel, 6,100 vehicles, 40 vessels, and 260 aircraft, plus participation from U.S. forces and six allied nations: Canada, France, Germany, the Netherlands, New Zealand, and the Philippines.
Why it matters
- First operational deployment of large unmanned surface vessel with a carrier strike group signals U.S. Navy commitment to autonomous maritime capability in contested Indo-Pacific waters.
- Seahawk's demonstrated autonomous navigation, collision avoidance, and remote supervision capability expands strike group sensor and mission options without increasing crewed personnel.
- Deployment demonstrates integration of autonomous systems into operational naval formations, validating autonomous vessel architecture for fleet operations and setting precedent for scaled adoption.
Going deeper
- Seahawk development followed DARPA's 2010 Anti-Submarine Warfare Continuous Trail program, with Leidos receiving $59 million for Sea Hunter in 2012 and $35.5 million for Seahawk in 2017.
- Seahawk delivered April 7, 2021, incorporated more than 300 lessons from Sea Hunter, which demonstrated 27 knots maximum speed, 12 knots cruising speed, and 10,000-nautical-mile range.
- Training during Keen Sword 2027 includes coastal missile deployments, integrated live firing, autonomous surveillance, and aircraft dispersal across Ryukyu Islands, Kyushu, Okinawa, and surrounding waters.
The fine print
- USS Theodore Roosevelt may receive follow-on deployment to Middle East after Keen Sword 2027 to relieve USS George Washington, but U.S. Navy has not confirmed transfer date or deployment.
