G.55.S Centauro (Silurante / Torpedo - Fighter)

anean Sea. By late 1942 the aging Sparviero was facing continually improving Allied fighters and anti aircraft defences.leading to the General staff exploring the idea of using a fighter aircraft for torpedo attacks. A fighter operating from Italian coasts with an operational range of 300–400 km (190-250 mi), would be capable of delivering a torpedo at high speed and evade enemy fighters or engage them after the attack run.

Fiat was asked to begin studies for a G.55 conversion to carry a 680 kg (1,500 lb) Whitehead torpedo, a shorter and more compact version of the standard weapon used by the SM.79. With the decision to develop a G.57, whose specifications included the capability of carrying torpedoes, all similar work on the G.55 torpedo fighter was suspended. Later, after the G.57 project was dropped, and given the Regia Aeronautica 's continuing need for an aircraft that could replace the SM.79, the Regia Aeronautica engineers undertook the task of converting the Centauro for the torpedo attack role. A production aircraft (military serial number MM. 91086) was modified to carry a 920 kg (2,030 lb), 5.46 m (17.91 ft) long torpedo. The radiator for the engine liquid cooler, positioned in the fuselage belly, under the cockpit area, was split in two, gaining a 90 cm (35 in) slot where two racks were mounted to carry the torpedo. The tailwheel strut was lengthened and equipped with a strengthened shock absorber, and a protective cone was added in front of the tailwheel. The two 12.7 mm (.5 in) Breda-SAFAT machine guns were removed, leaving the aircraft with the three 20 mm cannons only as fixed armament. Weight: 2,600-4,100 kg [17]

The aircraft, designated G.55S, first flew in August 1944 and was successfully tested in January 1945, [10] piloted by Adriano Mantelli. Despite the cumbersome external load, performance was good and the handling acceptable. The Regia Aeronautica ordered a pre-series of 10 examples and a production series of 100 aircraft, but the conclusion of the war put an end to the project. The G.55S prototype survived the war and, after being converted back to the Serie I standard, it became the first G.55 to be delivered to the newly formed Aeronautica Militare Italiana (AMI).
