The Batgyro was soon replaced by the Batplane, which debuted in Batman #1, and initially featured a machine gun.[4] The vehicle was now based on a fixed wing airplane rather than a helicopter, with a propeller at the front, although a bat motif was still attached to the nose-cone. The Batplane has undergone constant revision since its first appearance, and has even been depicted as having the capability to traverse underwater.[5] With the launch of the Tim Burton directed Batman film of 1989, the Batplane became known as the Batwing, a name which was carried over into the comics. The 2012 film The Dark Knight Rises adapted the Batplane to film, this time however the vehicle was referred to as The Bat.
