Background on the Semovente da 75/18
The Semovente da 75/18 is an Italian Self Propelled Gun developed in part on Germany’s successful use of the StuG III during the French campaign. The first Semovente M40 da 75/18 prototype delivery occurred on 10 February 1941. Pleased with the results, the Regio Esercito ordered 60 units. Delivery occurred in 1941 and shipped to the Italian divisions in Libya by January 1942. The intention was to use it as an interim vehicle until the P40 heavy tank became available.
Initially, the Semovente M40 da 75/18 used the same hull, suspension, and engine as the Fiat M13/40. In 1942, Ansaldo built 162 Semovente da 75/18 M41 using the upgraded Fiat M 14/41 chassis. In 1943, the Semovente da 75/18 M42 began using the Fiat M15/42 chassis and engine. Ansaldo built 190 Semovente da 75/18 M42s.
The vehicle mounted an obice da 75/18 mod. 34 field gun fixed in the superstructure. The front armor comprised of two 25 mm plates bolted together.
Most Feared by the Allied Tank Crews
Although mainly used as artillery, the Semoventi da 75/18 was quite effective against U.S. built M3 Grant and M4 Sherman medium tanks utilized by the British Army.
These units were of good quality and respected in the campaign in North Africa. In an anti-tank role, the 75 mm EP (Effetto Pronto; Ready Effect, or HESH rounds), was capable of piercing 3.14 inches (80 mm) of armor plating at 500 m.
