System - M3 armament sub-system.
Description : The M3 armament sub-system is a 48 tube 2.75 inch FFAR delivery system. The sub-system consists of the MARK 8 infinity reflex sight, two 24 tube 2.75 inch FFAR launchers, fire control system, and supporting structure. The rockets may be fired in single pairs or in ripples of 2, 3, 4, 6, or 24 pairs at the rate of 6 pairs per second. Each launcher mount has two explosive bolts that are fired by activating the JETTISON switch on the ROCKET ARMAMENT panel.

System - M23 armament sub-system.
Description : The M23 sub-system is attached to external stores hard point fittings on both sides of the helicopter. The two flexible 7.62mm machine guns M60D are free pointing but limited in traverse, elevation, and depression by cam surfaces and stops on pintles and pintle post assemblies of the two mount assemblies on which the M60D machine guns are mounted.

System - M59 armament sub-system.
Description : The armament sub-system M59 is attached to external stores hard points on each side of the helicopter. A 7.62 millimeter machine gun M60D mounted on its pintle post assembly is mounted on one side of the helicopter. A caliber .50 machine gun XM213 mounted on its pintle post assembly is mounted on the other side. Interchangeable base tube assemblies allow either machine gun with their respective pintle post assemblies, to be installed on either side of the helicopter.

System - M56 armament sub-system.
Description : The M56 mine dispersing sub-system is attached to external stores hard-point fittings on both sides of the helicopter and is electrically or manually jettisonable in an emergency. The mine dispenser is designed to provide release of mines from the 40 canisters with application of current through the intervalometer, which is part of the disperser electrical circuit. Total release of mines in all canisters is accomplished within a variable time span between each canister release, which is set by the pilot.

System - M52 smoke generator sub-system.
Description : The smoke generating sub-system basically consists of the oil tank assembly, pump and motor assembly, nozzle ring assembly, operating switch and fog oil level gage. The smoke generating sub-system discharges atomized fog oil into the hot exhaust gases of a helicopter engine. A dense white smoke is formed which settles rapidly to the ground when fog oil is released at altitudes less than 50 feet and air speeds less than 90 knots. The tank capacity is 50 gallons and provides approximately three minutes of smoke generator operation. The length of time the smoke screen will obscure enemy vision depends on wind conditions and the altitude at which smoke is released.
