Development edit
After the armistice of Cassibile signed in September 1943, Northern and Central Italy fell under German control. In 1944 the progress of the war led them to order a new Italian armoured vehicle for a tank-fighting role, based on the Semovente da 105/25 self-propelled gun. The result was the Semovente da 75/46, which was named Sturmgeschütz M 43 mit 75/46 (852) (i) by the Germans, following their naming convention.[1]
The 75/46 shared the same "M 43" hull of the Semovente da 105/25.[3] However, the 105 mm L25 howitzer was replaced by a long Cannone da 75/46 C.A. modello 34 – originally conceived as an anti-aircraft gun but also used as an anti-tank gun – which gave a higher muzzle velocity (750 m/s instead of 510) and a far greater effective range, being able to fire a 6.5 kg (14 lb 5 oz) shell up to 13,000 m (43,000 ft) away. This gun could be loaded with HE or armour-piercing rounds; when loaded with the latter, it could penetrate up to 90 mm (3.5 in) of armour from 500 m.[3][4]
The other main difference with its precursor was in the overall increased armour: sloped plates were applied to the casemate and others were added on the sides, above the tracks.[1] Due to these features and despite its origins, the 75/46 is considered a tank destroyer in every respect.[5]
Production edit
Between 1944 and the end of World War II in Italy, Ansaldo managed to assemble only 11[3][5] or 13[1] vehicles, all deployed exclusively by the Wehrmacht. Their standard camouflage, applied just after assembly, was Saharian Khaki background with reddish-brown and gray-green patches.[3]
