History
Development of the new US Army light tank in 1943 have focus on improving the light tank's firepower with a 75 mm gun. The new light tank design, designated T24 on 29 April 1943, required a lighter-weight and shorter-recoiling 75 mm gun than that seen on the M4 Sherman's 75 mm M3.[1]
Rock Island Arsenal was tasked with the development of the new lightweight 75 mm gun.[2] The basis of the new gun was the 75 mm T13E1, which has seen use as an aircraft mount on the B-25 bomber as the 75 mm M5.[2][3] The 75 mm M3 and T13E1 shared ballistic performances, but the T13E1 had thinner barrel walls, which shortened barrel life and can more easily overheat, and a T19 concentric recoil mechanism, which shortened the recoil length.[2][3] These design changes allowed the T13E1 a weight of just over 400 lb, compared to the 75 mm M3's 893 lb. weight.[3] The design was worked on with a new T33 concentric recoil mechanism in a T90 combination gun mount to fit within a light tank turret.[2][3] This new gun configuration and mount was tested in Summer 1943, and proved that the gun will work inside a tank turret with a 60 inches turret ring diameter.
When the T24 was accepted into service as the M24 Chaffee on 22 June 1944, the modified 75 mm T13E1 was likewise standardized as the 75 mm gun M6 in a M64 combination gun mount.[4]
An attempt was made to improve the 75 mm M6 gun in early 1945 with the 75 mm gun T21. The new gun featured a stronger breech assembly, improved firing mechanism, a fixed breech operating handle, and a hand cocking lever for the gun that was accessible to every turret crew member. The gun also featured a T13 single-baffle muzzle brake. The gun was eventually accepted as the 75 mm gun M17, but the war had ended by that point and so was the M24 production lines.[5]
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
