The new vehicles were also completed with a larger-caliber 76mm High-Velocity main gun, featured welded hulls (as opposed to cast) and were powered by Ford GAA V8 gasoline engines. The HVSS was applied to the M4A3 production model and gave rise to the M4A3E8 / M4A3(76)W HVSS designations - nicknamed "Easy Eight". While the addition made for a heavier and wider tank product, it improved the vehicle's operating ground pressure. First generation Shermans carried over several deficiencies from the M3 Grant Medium Tank line - from which it was largely based on - and this included its narrow track links as well as its Vertical Volute Spring Suspension (VVSS) system which gave poor ground performance.Įven as the war raged, work was actively being done on improving the Sherman's qualities and this resulted in the finalization of the "Horizontal Volute Suspension System" (HVSS) coupled to wider track links. This eventually led to the Sherman being produced across several "generations" over its service life. Throughout World War 2 (1939-1945), the classic American M4 Sherman Medium Tank was subject to many tests and programs to help the series maintain a viable presence on the battlefield - particularly against the latest generation of German tanks. ![]()
