C/SSV Seabiscuit

The C/SSV Seabiscuit (Cerberus Systems Space Vehicle) was a shuttle holding several Cerberus Commandos and a crew. The ship was attacked by an unknown enemy near Shepard's death, and was destroyed when a crew member overloaded the engines. Half of the crew survived, a quarter of them killed, the remaining vaporized by the atomic blast that destroyed the ship.
