1950, a re-engined NATC Patuxent Grumman F9F-3 Panther BuNo 122562 was fitted
with an experimental electro-hydraulically driven Emerson Aero X17A
roll-traverse turret housing four 0.50-inch machine guns.
The guns could be directed at any angle from directly forward to 20 degrees aft,
and the gun mount could be rolled the full 360 degrees in either direction. The
turret could roll at a rate of 100 degrees per second, and the guns could be
traversed at up to 200 degrees per second.
Although the tests with the turret went fairly well, delays in the development
of the associated radar and fire control system led to the project being
cancelled in early 1954.
