USS Atlanta (SSN-813) will be a nuclear-powered Virginia-class submarine of the United States Navy, the twelfth Block V attack submarines and 40th overall of her class.

The submarine will be the sixth U.S. Navy vessel named for Atlanta, Georgia.

Atlanta and sister ship Baltimore were ordered during the 2024 Fiscal Year budget at a combined cost of $9.4 billion.

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.
