US Navy operates only one Seawolf-class submarine as others undergo maintenance

As of April 2026, only USS Jimmy Carter remains operational, with USS Connecticut in repair until late 2026 and USS Seawolf sidelined until June 2029.
USS Jimmy Carter, designed for special missions rather than anti-submarine warfare, is currently the Navy's sole available Seawolf-class vessel, limiting high-end undersea combat capabilities.
The Seawolf-class, originally planned for 29 boats but reduced to three, reflects a post-Cold War strategic miscalculation now impacting US readiness amid rising Chinese and Russian submarine advancements.

As China launches its own 'Seawolf,' has the U.S. already lost its undersea advantage?
Was canceling the Seawolf fleet for a 'peace dividend' America's costliest naval mistake?

The U.S. Navy’s Seawolf-Class Submarine Crisis: Operating with Only One Active Boat Through 2029
Overview
Since the USS Connecticut collided with an uncharted seamount in 2021, it has been undergoing complex repairs delayed until late 2026 or 2027 due to unique design challenges and parts scarcity. With the USS Seawolf entering maintenance until 2029, the USS Jimmy Carter remains the only operational Seawolf-class submarine, carrying a heavy burden with its specialized espionage capabilities. This reduction to a single active boat creates significant strategic risks, mission gaps, and over-reliance on one asset amid a shrinking overall submarine fleet. The situation highlights critical lessons about fleet size, sustainment planning, and industrial base resilience essential for future undersea dominance.
