In December, 1942, Allied forces reported that new German armored vehicle designs were resistant to 57 mm anti-tank guns, the largest anti-tank gun available. The US Ordnance Department began preliminary studies on a gun design similar to the German 88 mm Pak 43/41 anti-aircraft gun which was then successfully being used as an anti-tank gun.
The 7.5 cm Pak 41 was one of the last German anti-tank guns brought into service and used in World War II and notable for being one of the largest anti-tank guns to rely on the Gerlich principle (pioneered by the German gun-designer Hermann Gerlich, who developed the principle in the 1920s, reportedly for a hunting rifle) to deliver a higher muzzle velocity and therefore greater penetration in ...
The Pak 43 was the most powerful anti-tank gun of the Wehrmacht to see service in significant numbers, also serving in modified form as the 8.8 cm KwK 43 main gun on the Tiger II tank, the open-top Nashorn and fully enclosed, casemate-hulled Elefant and Jagdpanther tank destroyers.
The complete vehicle was 10.2 m (33 ft) long, 3.71 m (12.2 ft) wide and 3.63 m (11.9 ft) high. Weighing about 188 metric tons, the Maus's main armament was the Krupp-designed 128 mm KwK 44 L/55 gun, based on the 12.8 cm Pak 44 towed anti-tank gun also used in the casemate-type Jagdtiger tank destroyer, with a coaxial 75 mm KwK 44 L/36.5 gun.
The 12.8 cm Pak 44 ended up becoming the standard main armament for the Jagdtiger heavy tank destroyer and a tank gun variant was the planned main armament for many future super-heavy tank designs in development during the last months of World War II, including the fully turreted Panzerkampfwagen Maus and E-100, as the 12,8 cm KwK 44 L/55 main gun.
In consequence, during World War II, both sides were compelled to make anti-tank guns self-propelled, which greatly increased their mobility. [18] The first self-propelled anti-tank guns were merely belated attempts to make use of obsolete tanks, such as the Panzerjäger I, which was a Czech 4.7-cm Pak (t) gun mated to a Panzer I chassis [a].
In 1941, the loss of huge amounts of anti-tank artillery created a need for a stop-gap anti-tank weapon, so famous USSR weapons designers such as Vasily Degtyaryov and Sergei Gavrilovich Simonov were tasked to design anti-tank rifles. Both were considered simpler and more suitable to wartime production than an updated Rukavishnikov rifle.
