Production: February 1942 – December 1943
The M4A1 (British Sherman Mk.II)
This first major version was introduced early on in February 1942. It had a fully cast, rounded upper hull. This rounded hull is a major demarcation to me, and one that quickly aids in understanding that you've entered a slightly different evolution.
Production of the regular M4A1 totaled 6281 machines until December 1943, but it was replaced by the M4A1(76)W, which received a more recent 76 mm (2.99 in) M1 main gun, of which 3396 of these improved models were built until March 1945. Performance of the regular “short” M2 75 mm (2.95 in) L/31 varied with the ammunition used, to a range from 259 m/s (850 ft/s) (smoke round) to 587 m/s (1926 ft/s) (APC M61), while the longer M3 L/40 allowed a 731 m/s (2400 ft/s) muzzle velocity. But the most efficient was the 1943 model 76 mm (2.99 in) M1 & M1A1 L/55, which had a 792 to 1036 m/s (2600 to 3400 ft/s) muzzle velocity with the HVAP ammo, being capable of piercing an 100 mm (3.94 in) steel plate at 450 m (1476 ft). Maximum range was 14 km (8.69 mi).
Following a painful war experience, the ammo racks and fuel tanks were protected by watery jackets. They were still flaming coffins when hit, but the crew had a marginal chance of not becoming crispy chicken wings. The commander cupola was also new, featuring 6 prismatic vision blocks 76 mm (3 inches) thick with laminated bullet-proof glass. The engine was the modernized Continental R975-C1.
Camo patterns varied greatly.
