USS Miami (SSN-811) will be a Virginia-class nuclear-powered attack submarine of the United States Navy, the tenth of the Block V boats and the 38th of her class overall.

The submarine was ordered in March 2021 for $2.4 billion. Her name was announced on 8 May 2024 by Secretary of the Navy Carlos Del Toro during the Miami Fleet Week with city native and singer Gloria Estefan as her sponsor. ^{[2] [3]}

Design

Compared to Blocks I-IV of the 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. ^[3]

Her namesake Miami has been carried by four ships of the US Navy, most recently on USS Miami (SSN-755), a Los Angeles-class attack submarine that was decommissioned earlier than planned after she was set on fire in 2014. ^{[2] [4]}
