Hiddensee is a former East German Navy corvette now part of the Battleship Cove site in Fall River, Massachusetts. Originally a Soviet vessel, the corvette was transferred first to the East Germany Navy, then the German Navy and ended her career in the United States.
Under the aircraft designation system used by the U.S. Navy pre-1962, Navy and U.S. Marine Corps versions were originally designated as the HTK, HOK or HUK, for their use as training, observation or utility aircraft, respectively.
