The two versions of the Vulcan Air-Defense System, the towed M167 and self-propelled M163 VADS, were developed by the United States Army Weapons Command at Rock Island Arsenal in 1964. They were accepted as a replacement for the M45 Quadmount in 1965, and first production M167s were delivered to the U.S. Army in 1967.

[ 22 ] [ 23 ] While the F-111B did not reach service, land-based, non-fighter F-111 variants were in service with the U.S. Air Force for many years ...
While a major leap forward in aircraft armament, all revolver cannon suffer from the effects of barrel wear, heat dissipation, and parts life. The final improved version of the M39 had barrel changes mandated at 4000 rounds. [8] The system would be replaced by the M61 Vulcan in aircraft for this and MTBF as well as weight considerations.

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 for the proposed F-14 ADC interceptor and replace the M61 Vulcan on the then-upcoming F-15 Eagle. The GAU-7/A was a 25 mm Gatling gun using telescoped ammunition with a combustible case developed by the Brunswick ...
The XM301 is a lightweight, three-barrel version of the M61 Vulcan.It is externally powered, relying on the same power delivery system as the Vulcan. It fires M50 and PGU-series ammunition found in the Vulcan, as well as newer lightweight X1031/1032 aluminum-cased ammunition at either 750 or 1,500 rounds per minute. [2]
The F-16C as procured by the Navy was equipped with the lighter AN/APG-63 radar set as flown in the F-16A and had a titanium wing spar as in other F-16s. It was not equipped with the M61 Vulcan gun system and had twin lens pods on both sides of the intake to enlarge the relatively small radar cross section of the F-16.
