The M3 light tank

was created by upgrading and improving the M2A4 light tank. Compared to its predecessor, it featured stronger armour and better mechanical properties (reliability). The prototype tank was unveiled in July 1940, with mass production taking place from March 1941 to October 1942 at the American Car and Foundry Co.

During production, the tank underwent many changes. The original design of the tank had a hexagonal turret, and the individual plates of the turret and chassis armor were riveted together. Later, the turret fabrication technology was changed to welding, and eventually the tank was fitted with a round-section turret for which welded homogeneous armor was used (as well as for the hull).

The chassis suspension was the same as M2A4 (coil springs). However, unlike its predecessor, the rear tension wheel was placed at ground level, which increased the contact area of the tracks with the ground and reduced the kerb weight. The tracks with rubber feet had a width of 295 mm and a link length of 140 mm. In total, the belt consisted of 132-134 links.

Two powerplants were designed to power the tank - a gasoline, 7-cylinder, Continental W670-9A radial engine (M3 tank) and a diesel, 9-cylinder, Guiberson T1020-4 radial engine (Guiberson T1020-4 M3 (Diesel) tank). Both versions used a manual transmission with five forward and one reverse speed. The 211-litre fuel tank gave the tank a range of up to 113 km. In the case of longer-distance movements, fuel supplies could be increased by using two additional tanks of 94.64 litres each, which were removed before the start of combat operations. The tank's wiring worked with a voltage of 12 V. The tank was equipped with a fire extinguisher (5 kg CO2) and a manual extinguisher (2 kg CO2). In addition, an M2 decontamination device was fitted.

The tank crew consisted of 4 persons. The driver's and assistant's workstations were in the forward part of the hull. Their forward view was provided by glazed portholes in the hatches. In a combat situation, the hatches were protected by armoured shields and the view was possible through a rectoscope. The commander-loader and gunner had seats in the turret. Access to the turret was possible through a hatch located in the raised dome, which also served as the commander's observation room - either through the open hatch in the safe zone, or through the protectoscopes in the combat zone (the first tanks produced were not equipped with protectoscopes, only visors). The turret allowed full-circle metering with manual drive. The SCR-245 radio station was used for communication.

The main armament of the tank was a 37mm cannon M5, or M6. Mated to the cannon was a Browning .30 caliber M1919A5 machine gun. The common lafette allowed the guns to be aimed from -10° to +20°. Originally the weapons were not stabilized, but later the lafette was fitted with a gyroscopic stabilizer to increase the accuracy of fire while the vehicle was moving. A machine gun M1919A4, intended as an anti-aircraft gun, was mounted on the turret. The M1919A5 machine gun was mounted in a ball bearing in the front of the hull, and the other two machine guns were mounted in the side sponsons.

For the tank's armament, 103 37 mm calibre shells (anti-tank M51B1 or M51B2, fragmentation M63 and smoke M2), 8270 rounds for the machine gun (.30) and 500 .45 calibre rounds for the submachine gun were carried. In addition, 12 hand grenades (cluster Mk. II - 4 pcs, assault Mk. IIA with M6 detonating fuse - 2 pcs, smoke M15 (white phosphorus) - 4 pcs and incendiary - 2 pcs). Anti-armour shells from 37mm cannon reached a muzzle velocity of 884 m/s at a maximum range of 14053 m. Their kinetic energy allowed to penetrate hardened steel armour with a thickness of 46mm at a distance of 1093 m.

In August 1941 a modification of the M3A1 was introduced, and in March 1943 the M3A2 light tank was introduced, which was essentially identical to the M3A1 except that it used a welded hull. Serial production of this type did not begin
