The USS Victorious (NCC-66012) was a Defiant-class Federation starship in service during the 24th century. The Victorious was a heavy participant in the Dominion War as part of the 219th Tactical Wing of Starfleet's Eighth Fleet, spending the first two-thirds of the war defending Andoria and later often fought along the front lines. During the early part of 2374, the Victorious was commanded by Captain Tethru Vag-Shurin (Last Unicorn RPG: The Dominion War Sourcebook: The Fires of Armageddon). The Victorious is named for the British aircraft carrier that served during World War II.
