The 14.5 × 114 mm cartridge (also known as M41 / 44 ) is a Soviet rifle cartridge. It is still used today.
history
In the early 1930s, an anti-tank rifle in the 12.7 × 108 mm caliber was developed in the Soviet Union . a. Borrowed from Tankgewehr 18 . Their penetration performance (15 mm at 90 °, 500 m) seemed to be insufficient shortly before Germany's attack on the Soviet Union , also due to the experience from the Spanish civil war . Therefore, in 1939, stronger ammunition and a corresponding anti-tank rifle were developed. The anti-tank rifle prototype was ready for testing in the summer of 1939, but was not put into series production. After June 22, 1941, the PTRS and PTRD anti- tank rifles were developed in a hurry .
The penetration rate of the cartridge with the tungsten core bullet BS-41 was 40 mm RHA at a distance of 100 m at a 90 ° angle of impact.
With the increase in armor thickness, the 14.5 mm cartridge was no longer able to pose a threat to enemy tanks as early as 1943 and (together with the PTRD and PTRS anti-tank rifles) therefore dropped out of the role of infantry anti-tank combat. It was still used against lightly armored vehicles such as armored personnel carriers as well as the side armor and chains of battle tanks. Later, the super heavy infantry machine gun Vladimirov KPW was developed for this ammunition , which was the basis for the anti-aircraft guns ZPU-1 , -2 and -4 as well as the KPWT board machine gun . The KPWT is the main weapon of the armored personnel carriers of the BTR series (from the BTR-50 to the BTR-80 ).
In the 1990s, the 14.5 mm cartridge was used again in single-shot weapons, now in the anti-material role , such as the NTW-20 / 14.5 .
species
The cartridge is available as a full armor-piercing steel bullet, with incendiary device, with a tungsten carbide core (AP) or as tracer ammunition.
