SAN DIEGO (May 8, 2021) U.S. Sen. Dianne Feinstein, from California, delivers pre-recorded remarks during the commissioning ceremony for the expeditionary mobile base USS Miguel Keith (ESB 5) at Naval Base San Diego. Miguel Keith is the Navy’s third purpose-built expeditionary sea base (ESB). While originally created to operate as a support ship under Military Sealift Command, Miguel Keith has been commissioned to provide greater mission flexibility in accordance with the laws of armed conflict. It is the first U.S. warship named for Marine Corps Lance Cpl. Miguel Keith, who was posthumously awarded the Medal of Honor for heroism in Vietnam.
