By 1943, it was becoming obvious to the German army that conventional anti-tank gun design had reached its practical limits. Traditional high-velocity guns that relied on kinetic energy to defeat heavily armored targets were becoming so bulky in order to deal with the new generation of tanks that they were becoming too heavy for front line use, and too expensive to produce.
It was designed as a close-support infantry gun firing a high-explosive shell (hence the relatively short barrel) but was also effective against the tanks it faced early in the war. From March 1942, new variants of the Panzer IV and StuG III had a derivative of the 7.5 cm PaK 40 anti-tank gun, the longer-barreled 7.5 cm KwK 40 . [ 1 ]

This is a list of tank main guns which are designed or used as the primary weapon of combat by tanks, such as light tanks, medium tanks, heavy tanks, or main battle tanks. Many tanks have other, secondary weapons installed in them, such as machine guns , autocannons and small calibre mortars , which are not included in this list.
In 1940, weapons were critically short; there was a particular scarcity of anti-tank weapons, many of which had been left in France. Ironside had only 170 2-pounder anti-tank guns but these were supplemented by 100 Hotchkiss 6-pounder guns dating from the First World War, [141] improvised into the anti-tank role by the provision of solid shot.

The design of the KwK 40 was adapted from the similar towed anti-tank gun, the 7.5 cm Pak 40. It replaced the 7.5 cm KwK 37 with its 24-calibre barrel, providing a huge improvement in firepower for mid-war tank designs. It came in two versions, 43 ("L/43") and 48 ("L/48") calibres long barrels, the former used during 1942 and early 1943, and ...
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].
The Type 5 Na-To (五式砲戦車, Go-shiki hōsensha), officially known as the Experimental 7.5cm self-propelled anti-tank gun Na-To (試製七糎半対戦車自走砲 ナト, Shisei nana-senchimētoru hantaisensha jisōhō Na-To) was the penultimate self-propelled anti-tank gun developed by the Imperial Japanese Army in 1945, [1] during the closing stages of World War II.
