Daryl Caudle, right, and Cmdr. Mattheww Horton, commanding officer of the Virginia-class submarine USS Delaware (SSN 791), following a commissioning commemoration ceremony for Delaware in Wilmington, Del., April 2, 2022. The initial commissioning took place administratively in April 2020 due to COVID restrictions at the time and is the first submarine to be commissioned while submerged. Delaware, the seventh U.S Navy ship and first submarine named after the first U.S. state of Delaware, is a flexible, multi-mission platform designed to carry out the seven core competencies of the submarine force: anti-submarine warfare; anti-surface warfare; delivery of special operations forces; strike warfare; irregular warfare; intelligence, surveillance and reconnaissance; and mine warfare.
