Summary

The 105 mm Gun T5 was large-caliber armament developed by the Americans for the purpose of anti-fortification and anti-armor. The first variant, the T5E1, was the main armament on the large American T95/T28. The cannon then became the main armament of the T29.

Game Usage

The 105 mm T5 is one of the largest caliber gun available for the U.S. tree. Equipping some of the more heavily armored vehicles such as the T95 and T29, it made these vehicles very potent against enemy vehicles. With the recent addition of the T13 APCBC round with explosive filler, its effectiveness against armor increased even more, able to take out most vehicles with a single penetration. The T32 APBC round is also potent in penetration value and slope normalization, able to penetrate the Tiger II's lower glacis in average combat ranges and the front glacis at close range (< 100 meters).

History of creation and combat usage

The development of the 105 mm Gun T5E1 started as the main armament of the experimental T29 Heavy Tank, though the gun itself was developed from a long line of anti-tank development when the US Army attempted to mount their 90 mm gun into a carriage for anti-tank purposes. The T8, the designation of the development for the anti-tank gun, was to be upscaled to the 105 mm due to experiences on the battlefield with newer German tanks being built in 1944. During the development, the Army proposal of heavily armored tank to push the assault deep into enemy territory brought the T95/T28, which will be mounted with the same 105 mm gun as well to give it an edge against enemy fortifications and armor.

However, as none of the vehicles mounting the gun, nor the gun itself, ever saw combat in World War II. Their projects only made it to testing and prototypes before being cancelled when the war ended before it could be issued.
