The M42 40 mm Self-Propelled Anti-Aircraft Gun, or 'Duster' as it is known, is an armored light air-defense gun built for the U.S. Army from 1952 until December 1959. Production of this vehicle was performed by the G M tank division. It used components from the M41 light tank and was constructed of all welded steel. The 500 hp, six cylinder, air-cooled, gasoline engine is located in the rear of the vehicle. A total of 3,700 M42's were built. The vehicle has a crew of six and weighs 22,500 kg (49,500 lb) fully loaded. Maximum speed is 45 mph with a range of 100 miles. Armament consists of fully automatic twin 40 mm M2A1 and a .30 cal.

Although the M42 Duster was initially designed in the anti-aircraft role, it found great success when used in the Vietnam War against unarmored ground forces.
