The Mk 61 105 mm Self-Propelled Howitzer was a French self-propelled artillery piece designed and built during the late 1950's for the French Army.


During World War II a number of nations produced self-propelled artillery. These ranged from heavily armored assault guns with 360° protection to lightly-armored open topped tank-destroyers and self-propelled guns. Often the chassis for these conversions came from tanks or artillery tractors and two such vehicles were the US built M7 Priest and M12 Gun Motor Carriage supplied to Free French forces during World War II. During the 1950's France began a rearmament program to replace both of these guns to provide mobile artillery support for their mechanized divisions. Like in World War II the chassis for these new weapons was a light tank the French AMX-13.


The new vehicle had the same five-wheeled torsion bar suspension with front drive sprocket, rear idler and three return rollers as the AMX-13. The road wheels had solid rubber tires and the metallic tracks could be fitted with rubber traction blocks to lessen damage to roads. An all welded box-shaped steel superstructure is mounted to the rear of the vehicle to provide 360° of protection from small arms rifle fire and shell splinters.[3] Although protected from all directions the vehicle lacks NBC (Nuclear, Biological, Chemical) capability and is not amphibious. The engine and transmission are at the front of the vehicle and the driver is on the left. The gun compartment has a commanders cupola with a periscope and 360° vision blocks. The cupola also has a ring mount for an external 7.5 or 7.62 mm LMG (Light Machine Gun). The gun compartment also has access hatches at the top and rear.[3]

The primary armament for the vehicle is an Obusier de 105 modèle 1950 howitzer with a wide range of elevation -4° to +66° but with limited traverse 20° right and left. Traverse and elevation are both manual. French, Israeli, and Moroccan vehicles have a gun barrel which is 23 calibers in length while Dutch vehicles have a barrel 30 calibers in length.[3] Both have a hydro-pneumatic recoil system below the barrel and both are fitted with a double-baffle muzzle brake. The gun fires semi-fixed 105 mm (4 in) ammunition and 55 rounds of ammunition could be carried in the gun compartment. Generally, 6 of the 55 rounds were HEAT (High Explosive Anti-tank) with the remaining rounds being HE (High-Explosive). The HEAT round could penetrate 350 mm (14 in) of armor at an incidence of 0° or 105 mm (4 in) or armor at 65°.[3]

The Mk 61 has more than likely been retired by its users and replaced by either 122 mm (4.8 in) or 155 mm (6 in) self-propelled artillery capable of 360° fire. The Mk 61 would be outranged, under armed and under protected to face today's rivals.[3]

Mk 62

A variant with a longer barrel and a turret capable of 360° of traverse was offered to Switzerland and although it was tested it was not adopted by them.[3]
