U.S. Navy's Columbia-Class Submarine Program Faces Delays and Construction Challenges
The U.S. Navy's Columbia-class ballistic missile submarine program, vital for nuclear deterrence, is facing significant issues related to construction and schedule delays. The lead submarine, USS District of Columbia (SSBN-826), is now over 60% complete but is projected to be delivered in 2029, 17 months behind schedule.
Twelve Columbia-class submarines are planned to replace the aging Ohio-class fleet, which is nearing the end of its service. The Columbia-class features a life-of-ship nuclear reactor and will carry 16 Trident II missiles.
The second and third submarines, USS Wisconsin (SSBN-827) and USS Groton (SSBN-828), are also under construction with expected deliveries in the early 2030s. Concerns from the Government Accountability Office highlight potential cost growth and schedule risks related to workforce and manufacturing challenges. The Navy aims for the fleet to achieve full operational capacity by the early 2040s, contingent on no further delays.
