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, but 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 physically shaped after the bat-emblem to such a degree.
The Bat-Signal is a distress signal device appearing in the various interpretations of the Batman mythos. It is a specially modified searchlight with a stylized symbol of a bat attached to the light so that it projects a large Bat emblem on the sky or buildings of Gotham City. In the stories, the signal is used by the Gotham City Police Department as a method of contacting and summoning Batman to their assistance in the event of a serious crisis and as a weapon of psychological intimidation to the numerous villains of Gotham City.
