M-42 Carriage, Self-propelled, Anti-aircraft, Twin 40mm, 25-ton, (Duster)
The M42 Duster series is based on the M41 "Walker Bulldog" chassis by fitting the twin gun mount inside the hull turret ring. Three models were standardized, M42 produced from 1951-1953, the M42A1 standardized in 1956, and M42A2, all with the nomenclature "Carriage, Self-propelled, Anti-aircraft, Twin 40mm, 25-ton, (Duster)."
The interior of the M42 Duster is divided into three areas: driving compartment at the front, stowage compartment in the center, and engine compartment in the rear. The driving compartment contains the driving controls and instruments. The seats for the driver and commander-radio operator are in the driving compartment. The stowage compartment serves as a base for the gun mount with space for 12 boxes of 40-mm ammunition. The engine compartment houses the main engine, auxiliary generator and engine, transmission, and fuel tanks. The gunner, squad leader, and cannoneer ride in the gun mount. The squad leader commands, via the intercommunications set AN/VIC-1, either from the commander's seat or the gun mount.
The 25 ton Duster is powered by a Lycoming AOSI-895-5 6 cyl. fuel injected 500 hp engine.
