Firebird (submarine)

The Firebird was a Soviet submarine in operation during the Cold War. In 1983, it was under the command of Captain Zhukov on a routine oil exploration run at the North Pole. There, its crew discovered an Ice Warrior buried in a block of ice. When awakened, this Ice Warrior, Skaldak, took over the sub and proposed to use its nuclear payload to start a full-blown nuclear war. Only the intervention of the Eleventh Doctor and Clara Oswald allowed the submarine to once again safely come under Zhukov's control. (TV: Cold War)
