F35 Cannon
Just read this 'According toGuns.com, the F-35 cannon can only fire 55 rounds per second, but it must fire relatively slowly to conserve ammunition. That conservation is important for the F-35, as the plane can hold only a 220-round magazine. If fired at 55 rounds per second continuously, the F-35 would run out of ammunition within four seconds..
Don't think that is much cop.
