Virginia Class Submarines

The Virginia class, also known as the SSN-774 class, is a class of nuclear-powered cruise missile fast-attack submarines, in service in the United States Navy. Designed by General Dynamics Electric Boat (EB) and Huntington Ingalls Industries, the Virginia-class is the United States Navy’s latest submarine model, which incorporates the latest in stealth, intelligence gathering, and weapons systems technology.

Virginia-class submarines are designed for a broad spectrum of open-ocean and littoral missions, including anti-submarine warfare and intelligence gathering operations. They are scheduled to replace older Los Angeles-class submarines, many of which have already been decommissioned. Virginia-class submarines will be acquired through 2043, and are expected to remain in service until at least 2060, with later submarines expected to remain into the 2070s.

Block V

Block V involves 10 boats and may incorporate the Virginia Payload Module (VPM), which would give guided-missile capability when the Guided Missile Submarines (SSGNs) are retired from service. The Block V subs are expected to triple the capacity of shore targets for each boat. Construction on the first two boats of this block was expected to begin in 2019 but was pushed back to 2020, with contracts for long lead time material for SSN-802 and SSN-803 being awarded to General Dynamic’s Electric Boat.

The Block V subs were confirmed to have an increased length, from 377 ft (115 m) to 460 ft (140 m), and displacement, from 7,800 tons to 10,200 tons. This would make the Block V the second-largest US submarine, behind only the Ohio-class (at 560 ft; 170 m).
