Macchi C.200s. Internal volume was over 77 m³ (2,700 ft³), and could carry up to 60 soldiers, eight torpedoes or 12 tonnes (13 tons) of cargo. After many changes in design, the first P.108T flew on 7 September 1942. Although the 148ma Squadriglia was intended to use both P.108Cs and P.108Ts, only a few were built before the Germans took control of production, subsequently at least 11 other examples were completed. Four P.108Cs and five P.108Ts were handed over to the Luftwaffe and used on the Eastern Front, notably during the 1944 evacuation of Axis troops following the Crimean Offensive. The P.108C (civil airliner, with 32 seats) and T (military transport) were more reliable than the bomber variants, and their capability of carrying heavy loads (such as two dismantled fighters) was important, as the Luftwaffe did not have many heavy transport aircraft, relying mainly on the smaller Ju 52s. These aircraft also had four 13 mm (.51 in) MG 131 machine guns as defensive armament, with one in a dorsal turret, one in a ventral position, and two waist positions. One example, known as "Die General", was destroyed on Salonicco airfield. Transportfliegerstaffel 5 operated most of these aircraft and used them until the end of the war, with one assigned to the links between Italy and Germany and the other on the Eastern front. On 10 August 1944, an air raid destroyed six of them. Another four were destroyed or captured in 1945. The P.108T-2, a postwar version, was proposed but without success, and thus ended the P.108 series history. P.133 The final development of the P.108, the P.133 prototype, was almost complete by the time of the Armistice (8 September 1943), but the program was dropped soon afterwards and the aircraft was never finished. It was designed to have a lighter structure and several improvements in performance, which were partially influenced by a captured B-24, with a potential speed of 490 km/h (304 mph), 6 20 mm cannon, 4 12.7 mm (.5 in) machine guns and a bomb load of up to 4,800 kg (10,600 lb). Operational history P.108Bs were deployed in the Mediterranean and North African theatres and first saw action in an unsuccessful day mission against a destroyer on 6 June, releasing 10 160 kg (350 lb) bombs. The aircraft were effectively used a few weeks later, with a night bombing raid over Gibraltar on 28 June
