GAU-7 cannon
The Ford-Philco GAU-7/A was an abortive program initiated by United States Air Force in the late 1960s to develop a new cannon to replace the M61 Vulcan on the then-upcoming McDonnell Douglas F-15 Eagle. The GAU-7/A was a 25 mm Gatling gun using telescoped caseless ammunition. It was intended to have greater range and hitting power than the 20 mm Vulcan, while the caseless ammunition would have alleviated the problems of either storing or ejecting spent cartridges, both of which present considerable problems for jet aircraft. Despite great expenditure, the project and its ammunition proved to be a failure, and it was cancelled in 1974. The F-15 therefore retained the M61A1 cannon, as have most U.S. fighter aircraft since 1956.
