From Wikipedia, the free encyclopedia
USS Tang (SSN-805) will be a nuclear-powered, Virginia-class attack submarine in the United States Navy. She will also be third United States Navy vessel with the name tang, a large family of tropical fish. Secretary of the Navy Kenneth Braithwaite announced in a 17 November 2020 press release that the submarine will be named USS Tang, in honor of a storied WWII submarine. This is the second of four new Virginia class members named in honor of WWII submarines with very successful combat records.[3] Ordered on 2 December 2019, she is the fourth of the Block V boats, the first boats of the class to include the Virginia Payload Module.

Design
Compared to Blocks I-IV of Virginia-class submarines, Block V vessels will incorporate previously introduced modifications to the base design in addition to a Virginia Payload Module (VPM). The VPM inserts a segment into the boat's hull which adds four vertical launch tubes. Each tube allows for the carrying of seven Tomahawk strike missiles, increasing her armament to a total of 40 missiles.[4]
