If US Navy shipyards (General Dynamics Electric Boat and Huntington Ingalls Industries’ Newport News Shipbuilding) can cut the build time from 66 months to 60 months then the buildrate for Virginia class attack submarines will be increased. This will enable the production rate of US submarines to increase to 3 completions per year. It will be one Columbia class sub and two Virginia class subs.[contact-form][contact-field label=”Name” type=”name” required=”true” /][contact-field label=”Email” type=”email” required=”true” /][contact-field label=”Website” type=”url” /][contact-field label=”Message” type=”textarea” /][/contact-form]
They have already reduced the delivery timeline by two years and cut cost by 20 percent, all while adding in greater capabilities through block upgrades, Johnson said. By the end of the Block IV submarine production, the yards will be on 60-month construction cycles, followed by three months of testing and a three-month post-shakedown availability, for a total of a 66-month delivery timeline.
The Columbia and the Virginia Payload Module would be a tough transition for the Navy-industry team.
Virginia-class submarine production revved up the two shipyards to a current two-a-year rate – this is the first year in recent history the Navy has both bought two submarines and delivered two submarines.
This discussion of two or three submarines a year matters in order to get the total nuclear submarine fleet from 48 boats to 66 subs. Building two a year in every year would get the Navy to 66 SSNs 2048.
