The 155 mm howitzer motor carriage M41 (also known as the M41 Gorilla) was an American self-propelled artillery vehicle built on a lengthened M24 Chaffee tank chassis that was introduced at the end of the Second World War.

[4][2] Equipped with a M1 155 mm howitzer with a heavy recoil-absorption spade at the back, the T64E1 was intended to the supplement the earlier M12 Gun Motor Carriage.

[6] After the T64E1 underwent trials at Aberdeen Proving Ground in December 1944, minor modifications were made and production began by the Massey Harris agricultural equipment company in May 1945.

[8] Additional tasks are assigned to certain gunners M41s were used in action in the Korean War, where they were useful in providing support during the early mobile phase of the conflict.

Like other contemporary US Army self-propelled artillery, the open-topped gun compartment left the crew vulnerable to small arms fire and shrapnel, and the engines were sometimes criticized for being underpowered.

Nonetheless, in a conflict in which enemy units frequently infiltrated or overran forward positions, the battlefield mobility, defensive firepower, and armor of the M41 was seen as being greatly preferable to that of towed artillery pieces,[11] and the performance of the 105 mm M7 howitzer motor carriage and M41 in the war influenced the U.S. Army to develop new self-propelled artillery in the 1960s, such as the M109 Paladin, that would almost entirely replace towed field howitzers.
