USS John H. Dalton (SSN-808) will be a nuclear-powered Virginia-class submarine for the United States Navy, the seventh of the Block V attack submarines and 35th overall of the class. She will be the first U.S. Naval vessel named for John Howard Dalton, the 70th Secretary of the Navy and a former submariner who, after graduating with distinction from the U.S. Naval Academy in 1964, served aboard the attack submarine USS Blueback (SS-581) and the ballistic missile submarine USS John C. Calhoun (SSBN-630).[2]

The submarine's name was announced on 28 February 2023 by Navy Secretary Carlos Del Toro at the Naval Academy in Annapolis, Maryland.[3]

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]
