US Navy Awards $101M to General Dynamics Nuclear Sub Program

The U.S. Navy has awarded a $101.3-million contract modification to General Dynamics Corp.’s (IW500/35 )  Electric Boat subsidiary to continue development work for the Common Missile Compartment of the forthcoming Columbia-class nuclear submarine — a replacement series for the Navy's current Ohio-class and the United Kingdom's Successor-class ballistic-missile submarine. The contract modification authorizes Electric Boat to procure 22 missile tubes for manufacturing of the Common Missile Compartment.

Replacing the Ohio-class has been long-term project: it has been in discussion for nearly a decade, and in 2012 the Navy issued a five-year contract worth up to $1.85 billion to General Dynamics for research and development work. That initial contract covered design costs and continuing design work for a new common missile compartment for nuclear submarines – a project begun by the Navy with Electric Boat in 2008.
