USS Valiant (NCC-74210)
Class: Defiant
Registry: NCC-74210
Captain: Ramirez
The USS Valiant began service as a training vessel for the elite cadet corps Red Squadron at Starfleet Academy. It was caught within enemy territory when the Dominion War broke out. All the officers were killed in battle and the dying Captain Ramirez appointed Cadet Tim Watters to command the ship.
Due to the ship's orders to maintain radio silence, Starfleet was unaware of the deaths of the ship's officers and continued issuing orders during the war. Instead of ordering it to return to base, for some reason Starfleet ordered the ship to collect information on a Dominion battleship in their vicinity. Watters -- despite his inexperience and lack of training -- decided to carry out these orders. The Valiant subsequently engaged the battleship instead of getting their observations back to Starfleet. Having a crew of nothing but cadets and being vastly out-classed, the Valiant was destroyed.
