The Window Mounted Weapon System for Black Hawk Helicopters consolidates the mount, magazines, and control systems into a single package according to operational needs. It can be stowed away during flight for fuel efficiency then deployed for crew-served use when needed. It is compatible with a variety of mechanically and electrically-operated 7.62mm weapons such as the M240 and M134, easily integrating with new or existing 7.62mm arsenals.
