AC-47

AC-47 gunship - one gatling gun points out the cargo door, and one each points out of the two windows forward of the door.

The AC-47 is a cargo plane that has high volume automatic weapons directed to fire perpendicular to the plane's flight. The weapons were mounted in the C-47, a plane essentially identical to the commercial DC-3. The plane's pilot would fly the plane so that it circled an area where enemy ground forces were believed to be located.

The planes first saw operational use in Vietnam.

Currently the United States Air Force fields planes with more advanced weaponry called the AC-130
