U.S.S. Valiant NCC-75418

The Defiant class^[1] starship Valiant was assigned to Starfleet Battle Group Omega, which was assigned to rendezvous with the U.S.S. Enterprise NCC-1701-E near the Bassen Rift in an attempt to intercept Praetor Shinzon‘s Scimitar and prevent it from annihilating Earth. Fortunately, the Enterprise, with the aid of two Mogai class warbirds, was able to destroy the Scimitar before it entered Federation space.^[2]
