History of Development

The self-propelled anti-aircraft gun M42 was developed as a variant of theM41 Walker Bulldog tank. It was intended to replace the M19 self-propelledanti-aircraft gun, which utilized the chassis of the M24 Chaffee tank. In 1950the work started on the prototype designated T141. The vehicle utilized thechassis of the M41 tank. Its rear portion was almost unchanged; a turret withtwin 'Bofors' anti-aircraft gun was installed in the center of the vehicle. Theturret was similar to that used in the M19, the most important modification toit was installation of hydraulic elevation and traverse mechanisms, workingtogether with the M38 computing sight. The turret was also fitted with readyammo bins. Additionally, the vehicle's driver's and commander's compartment waslarger than in the M41 and had one large front hatch and two smaller hatches onthe top plate.

After the testing, production of the vehicle started in 1952 under thedesignation M42. The vehicle had a 500 horsepower gasoline ContinentalAOS-895-3 engine, like M41 and M41A1, which gave a very poor mileage. In 1956M42s were upgraded with improved AOS-895-5 fuel injected engine, whichincreased the range substantially. Vehicles with this, and other minormodifications were designated M42A1.

Main armament of the M42 are the famous 'Bofors' guns, built in the USAunder Swedish license, that proven their high value in the World War II and inKorea, although in the latter conflict they were mainly used for groundsupport. In the M42A1 the guns were fitted with improved optics. The ammunitionwas fed by two assistant gunners in four-round clips, 100 of which were carriedon the vehicle in large boxes, one on each side. Lockheed and Sperryconstructed prototypes of fire control radars for the M42, but none of thedesigns was put into service. With no radar the use of the gun was limited toslow moving targets and visibility allowing the use of optical sights. When theSoviet Union introduced the new generation of jets, the value of the M42 asanti-aircraft weapon largely decreased.

Cadillac/General Motors Company produced the M42. As the production ended in1959 3700 of M42s and M42A1a were built. These vehicles replaced the M19s andvarious half-track mounted anti-aircraft guns, like the M16, M17 or similar.Later the M42 served in the National Guard and also in foreign armies under theMilitary Assistance Program. In the end of the sixties the limitations of theM42 were evident and the M163 'Vulcan' begun to replace it. About the same timethree battalions using M42 were sent to Vietnam.

In Vietnam there wasn't enough work for which the M42 was built. Because ofthat it was decided to use it for ground support. M42 was very successful inperimeter defense, base security and convoy escort roles. The nickname 'Duster'came from the clouds of dust the vehicle raised while traveling in a convoy.The parameters of the 'Bofors' gun made the Duster very effective in thejungle, in the presence of dense vegetation. Like was the case with other kindsof weapons the crews converted their machines to better adopt them to theconditions of the Vietnam War. The operators of the Dusters removed their flashsuppressors from the gun barrels and replaced the M1919A4 machine gun with theM60 machine gun or even two of them to increase short-range firepower.

Best-known instances when the Dusters were used in Vietnam are their servicewith the 9th Infantry Division in the Mekong delta and also their role inoperation Pegasus which successfully reopened the supply route to the encircledMarine outpost of Khe Sanh.

The model shown above depicts a vehicle that was posted at Khe Sanh combatbase before the siege. After the base was cut off, this vehicle helped todefend it throughout the siege. On July 5th, 1968 after the base was closeddown and abandoned, it was the last American vehicle to leave the base.
