Colonel Borlese of the artillery suggested a self-propelled design using the M13/40 chassis with later vehicles using M14/41 chassis. First prototypes were tested in early 1941 and production started in late 1941. Equipped artillery assault groups of 2 batteries of 4 each and in 1943 3 batteries of 6 each. First saw service with Ariete in North Africa.
A need for an AFV with a more powerful gun lead to the Semovente, which were inspired by the German Sturmgeschütz.
Semovente da 75/18 M41
The Semovente da 75/18 M41
was fitted with a 75 mm Ansaldo L/18
. The HESH (High Explosive Squash Head) round could penetrate 2.8" (70 mm) of armor.
There was a muzzle brake and a flash eliminator installed. The recoil system was inside the gun cradle and was in a gimbal mounting. The sighting gear was on the right side. There was a bracket that had a dial sight which projected through an aperture in the roof.
Semovente M.41M da 90/53
||5.63"@0° at 500 yards
The Semovente M.41M da 90/53
used a cannone da
90/53. It was a very potent gun that was similar in performance to the German 88 mm Flak
It was felt that the 90 mm gun could engage the enemy at long range and thus the crew wouldn't need armor protection. Producing the gun as an anti-aircraft gun received priority.
