Background on the Semovente da 105/25

The Semovente da 105/25, also known as the “Bassotto” (Dachshund) is considered to be the most powerful Italian Self-Propelled Guns (SPG) built during World War Two. It utilized a 105 mm 25 caliber howitzer on an M43 chassis. This chassis was the same as the M 15-42, but widened 7.9 feet (2.4 meters). The hull superstructure had 70mm of armor protection and the rest of the vehicle’s armor ranging from 25 mm to 50 mm.

The Semovente da 105/25 came into production on 02 April 1943. The Italian Army put in an order of 200 units, but only 12-30 were delivered before the Armistice. The Semovente 105/25 proved its effectiveness when the 135th Armored Division “Ariete II” utilized them against the Germans near Rome following the Armistice.

The 105/25 had welded plates with the exception of the front slope and casemate which continued using bolts and rivets.

The 105 mm howitzer had a 36° horizontal traverse and a -10° to +18° vertical traverse. Secondary armament consisted of an 8mm Breda 38 machine gun.
