On 26 March 1941, the P.108T military cargo version was ordered. This unpressurised variant was fitted with one Caproni dorsal turret, one Breda in the ventral turret, and two flank machine guns, all of 12.7 mm (.5 in) calibre, and was capable of 440 km/h (270 mph). Through a ventral door 4.8 m (15 ft 9 in) long and 1.9 m (6 ft 3 in) wide, it was possible to fit two 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.
