General Dynamics Electric Boat has won a $2 billion contract modification to continue long-lead work for the Block V Virginia-class attack submarine (SSN-774) program, according to a Monday Pentagon contract announcement.
“The award modifies a contract awarded in 2017 that provides funding for long lead time material for steam and electrical plant components, main propulsion unit and ship service turbine generator efforts and miscellaneous hull, mechanical and electrical system components,” Electric Boat said in a Tuesday statement. “This modification brings the overall contract value to approximately $3.2 billion.”
The award follows a 2018 contract modification of $692.2 million for long-lead materials for the modified Virginia attack boat design and an anticipated block buy for the submarines later this year.
Nine of the ten of the Block Vs feature the Virginia Payload Module that will stretch the hull by 84 feet to accommodate four payload tubes in the center of the submarine. The tubes that are designed to fire Tomahawk Land Attack Missiles. Attack boats with the VPM are planned to field 40 Tomahawks apiece.
The VPM module on the planned attack boats will eventually replace the capability of the four Ohio-class guided-missile submarines that were converted from ballistic missile submarines to field land attack missiles.
The Fiscal Year 2020 budget submission requests about $10 billion for the first three Block V hulls as part of a planned ten-boat buy expected to be awarded in April, according to Navy budget documents released this week.
