km (2,200 mi) with 600 kg (1,300 lb). Though much better than a typical Italian bomber (800–900 km/500-560 mi carrying 1,000 kg/2,200 lb), this was not impressive compared to the Avro Lancaster, able to fly 3,100 km (1,900 mi) carrying 4,000 kg (8,800 lb), and the B-24, about 3,220 km (2,000 mi) with the same load. The SM.82, normally with around half of the P-108's fuel (around 5,500 L/1,500 US gal), was able to reach long-range targets, such as Gibraltar, when adapted to carry the necessary additional fuel. Bomb load The P.108 had a large bomb bay which was capable of carrying 3,500 kg (7,700 lbs) of bombs. Depending on the target - these were uploaded either as: 7 × 250 or 500 kg (550 or 1,100 lb) bombs. 34 × 100 kg/220 lb (true weight: 129 kg/284 lb). 38 × 50 kg/110 lb (true weight: 69 kg/152 lb) bombs. The bomb bay was located centrally in the fuselage, and divided longitudinally into three sections which prevented it from carrying heavier bombs like the 800 kg (1,800 lb) types. This was a considerable limitation, whereas the SM.82 was capable of accommodating larger loads (being able to be used both in transport and the bomber role). In the torpedo-bomber configuration, three torpedoes could be carried under the belly and the wings. Defensive armament The defensive armament of the first P.108 series consisted of eight Breda-SAFAT machine guns. One Breda "O" 12.7 mm (.5 in) with 450 rounds was fitted in the nose, and a Breda "G9" 12.7 mm (.5 in) in a retractable ventral turret, with 400-450 rounds per gun. In addition to these two fully hydraulically powered turrets, there were two 7.7 mm (.303 in) guns in the flanks, with 500 rounds per gun. The wing armament consisted of two remote-controlled, hydraulically powered Breda "Z" turrets with 600 rounds per gun in the outer-engine wing nacelles, linked to one of the two cupolas in the fuselage "hump", with an operator in each. The wing turrets represented the most innovative aspect of the P.108's technology. Although considered a very advanced design, the operational suitability of the wing nacelle turret installations was questionable: P.108A In response to a request in November 1942, the P.108A Artigliere "gunship" was developed for anti-shipping duties to supplement torpedo bombers. It was armed with a modified high velocity Cannone da 90/53 gun mounted in a redesigned nose.
