When the U.S. Navy’s new SSBN (X) conducts its first patrol in 2031 it will be an entirely new vessel, but the boat will initially rely on life-extended 1990s vintage Trident II D5 submarine-launched ballistic missiles (SLBMs) to perform its nuclear deterrence mission. The Navy currently expects to keep the D5 in service into the 2040s, after which it may replace the long-serving weapon with a new missile. Read More

Ohio-class Replacement Details

The Ohio-class Replacement nuclear powered ballistic missile submarine (SSBN) is the Navy’s planned sea-based strategic nuclear deterrent. U.S. Navy officials outlined the capabilities of the boat this month.

“The Ohio Replacement is not, is not, a multi-mission platform,” Capt. William Brougham, US Naval Sea Systems Command (NAVSEA) Ohio-class Replacement Program Manager, said at the 2012 Naval Submarine League Symposium in Falls Church, Va. on Oct. 18.
“We don’t turn into a multi-mission platform that’s going to go off and do things that you see on television,” he said.

The Ohio Replacement is scaled back from the initial Analysis of Alternatives (AoA) for the program, then dubbed SSBN(X), conducted by NAVSEA in 2009. The initial AoA called for a boat that would have cost $6 to 7 billion but with the reduction in capability the Ohio Replacement drove costs down to $5.6 billion a copy. The eventual goal of the reductions is to produce the boats at $4.9 billion a copy.
