M-42 was a 45-mm Soviet light semi-automatic anti-tank gun. Full official name is 45-mm anti-tank gun model 1942 (M-42) (Russian: 45-мм противотанковая пушка образца 1942 года (М-42)). These guns were used from 1942 until the end of Great Patriotic War.

History

The M-42 was developed by the No. 172 Plant in Motovilikha as an upgrade of the 45-mm anti-tank gun M1937. The gun received longer barrel, shells with more powerful cartridge and thicker shield (7 mm instead of 4.5 mm). Some minor changes were also introduced in order to speed up production.

These guns were used from 1942 until the end of Great Patriotic War. In 1943, due to its insufficient anti-armor capabilities against new German tanks such as Tiger, Panther and Panzer IV Ausf H, the M-42 was partially replaced in mass production by more powerful 57-mm ZiS-2 anti-tank gun. However the M-42 remained in production as it was quite effective against lighter vehicles and could pierce the side armour of Panther and Panzer IV Ausf H. Fragmentation shell and canister shot gave the gun some anti-personnel capability.

Mass production of M-42 ceased in mid-1945. The total number of guns produced is 10,843.
