Definition of A-3 skywarrior

The Douglas A-3 Skywarrior was a strategic bomber built for the United States Navy, and among the longest serving; it entered service in the mid-1950s and was not retired until 1991. For many years after its introduction, it was also the heaviest aircraft ever flown from an aircraft carrier, earning it the unofficial nickname "The Whale".
