“The US shipbuilding industry is a shadow of what it was in the final years of the Cold War. The Navy is reliant on only a handful of major shipbuilders that design and construct different ship classes: Huntington Ingalls Industries (aircraft carriers, submarines, amphibious ships, destroyers), General Dynamics (submarines, destroyers, support ships), and Fincantieri Marinette Marine Corporation (frigates). Higher production rates would require infrastructure costs and a larger workforce. Repair and maintenance are likewise constrained by the few public yards available.
A Department of the Navy review earlier this year found that top US Navy shipbuilding projects, from new submarines to surface ships, are delayed by years and facing ballooning costs.
The longest project delays, expected to be at least three years, are for the coming Block IV Virginia-class attack submarines and the Constellation-class guided-missile frigate. The Navy’s first Columbia-class ballistic missile submarine, a priority for the Pentagon, isn’t expected to arrive until 12 to 16 months after its planned delivery, potentially leaving a hole in readiness plans for the nation’s nuclear forces. And the Navy’s next Ford-class carrier, USS Enterprise, faces a delay of 18 to 26 months.”
…
“the US needs to make significant investments in rejuvenating its military shipbuilding capabilities and capacity, ramp up production, and streamline its design process. A clearer strategy for industry and establishing stable supply chains, as well as hiring and keeping talented workers, is critical, too. Larger investments and drastic changes may be needed to build and maintain a force beyond 300 ships.”
