The Batwing was Batman’s custom-built air combat vehicle.
The craft was fully armed with miniguns and missiles.
It is unknown where the vehicle was stored, yet it was presumably kept somewhere near the grounds of Wayne Manor or in the Batcave.
Although the notion of Batman possessing and flying a Bat-themed aircraft has been around in comics since 1939, the Batman 1989 film first introduced the classification of “batwing”.
The movie’s Batwing was also the first of any Bat-aircraft to be phyically shaped after the bat-emblem to such a degree.
