The Firebird surfaced. (TV: Cold War)

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 through the principle of mutually assured destruction. 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)
