Cant Z.501 Gabbiano - Italeri 1/72

The CANT Z.501 Gabbiano (Italian: Gull) was a high-wing central-hull flying boat, with two outboard floats. It was powered by a single engine installed in the middle of the main-plane and had a crew of 4-5 men. It served with the Italian Regia Aeronautica during World War II, as a reconnaissance aeroplane. During its debut in 1934, it set a world distance record. However it was obsolete by 1940, but was still used throughout World War II, suffering many losses. Few of them remained in service until 1949.

Record flights

The production aircraft had an endurance of 12 hours. However, the record-breaking version, as was quite common at the time (mainly due to the low fuel consumption of the piston engine), greatly exceeded this. The USA had established a new endurance record of 3,860 km (2,400 mi); a Z.501 with the civilian registration I-AGIL was used to re-take the record in accordance with dictator Benito Mussolini's wishes. It was manned by Stoppani and two others, fitted with a special metal three-blade propeller, and other modifications
On 19–20 May 1934, the modified Z.501 established a new seaplane distance record of 4,130 km (2,570 mi), by flying from Monfalcone to Massawa, in Eritrea, in 26 hours and 35 minutes. This distance record was lost to a French aircraft that flew 4,335 km (2,694 mi) on 23 June the same year, so another record flight was made on 16 July. The plan was to fly to Djibouti, a distance of 4,700 km (2,900&nbs p;mi), but instead the aircraft flew 4,930 km (3,060 mi) to Berbera, Somaliland, in 25 hours.

Military service

Z.501's were used for search-and-rescue missions and anti-submarine patrols. The Z.501 was put into service with some modifications, including; turrets for the machine guns, and some reinforcement of the airframe that increased the overall weight by 500 kg (1,100 lb). The more powerful 656 kW (880 hp) Isotta-Fraschini Asso XI.RC engine was fitted, but even with an additional 97 kW (130 hp), the maximum speed dropped to 245 km/h (152 mph), cruise speed to 200 km/h (120 mph), and range to 2,400 km (1,500 mi).
The first units equipped were No.141 Sqn., Eritrea, No.83 Group, Augusta, No.85, Elmas, and No.62, Spain (for operations). By the time Italy entered World War II on 10 June 1940, 202 aircraft were in service in 15 squadrons. They were used by 20 Sqn. and patrolled the Mediterranean, as well as performing air-sea rescue operations. During the short campaign against France, seven Z.501s were destroyed by a French attack on their base in Sardinia. Another crashed the next day. In July, encounters with Royal Navy Fleet Air Arm fighters and accidents claimed many Z.501s, with a total of 11 destroyed in action, while the number that were operational dropped to 77. The Z.501 operated in all theatres and 62 aircraft were lost in 1940, leaving 126, of which only 87 were operational.New orders were placed with the manufacturer Aeronautica Sicula.
At the end of 1941, there were Z.501s in 15 of the 27 squadrons dedicated to naval reconnaissance. Strangely, the number of operational aircraft increased to an average of 100, rising six months later to 108 in 11 squadrons, probably due to the arrival of new aircraft. They were responsible, in collaboration with Italian ships, for the destruction of HMS Union and damaged three other submarines. But their effectiveness was limited by their bombload of only four 50 kg (110 lb) or two 160 kg (352 lb) bombs.
By the end of 1942, there were 199 aircraft in service, 88 of which were operational. Maritime reconnaissance had at that time 290 aircraft in total. By September 1943, there were still 240 aircraft assigned to maritime reconnaissance: only 84 were Z.501s, in three squadrons, and another 11 (mixed), out of 20 in total. Only around forty aircraft were operational. Total production, 218 by CANT and 236 by Aeronautica Sicula, but 12 incomplete aircraft were captured after the invasion of Sicily. Later, Aeronautica Sicula repaired many of the ICAF aircraft. Some modifications were adopted during production, such as the removal of the nose machine gun; it was replaced by an enclosed fairing.
Some Z.501s were supplied to Romania and to the Nationalists during the Spanish Civil War. Following Italy's surrender in 1943, a few of these flying boats continued to operate with both the Axis Aeronautica Nazionale Repubblicana and the Allied Italian Co-Belligerent Air Force. After the armistice, several flew to southern Italy, including the nine aircraft of 149 Sqn with 80 persons aboard. In October, there were 16 aircraft operational in southern Italy, which dropped to 10 by May 1945. The squadrons involved were Nos 141, 147, and 183. After the war 183 Sqn. was based at Elmas with four Z.501s, and these were scrapped in 1950.

Combat performances

Generally, the Z.501 had a mixed reputation. It was pleasant to fly, having low wing loading and good performance (when it was first introduced). It was quite reliable despite having only one liquid-cooled engine. However, there were problems with the durability of the wooden fuselage, particularly the aircraft built during the war. Its seafaring qualities were poor and the aircraft was susceptible to bad weather conditions. The fuselage would often break up in rough seas. Another problem was the engine nacelle: if the aircraft landed heavily the propeller could crash down into the cockpit.
The aircraft was used in the reconnaissance role thanks to its long endurance, but it was very vulnerable to enemy fighters or even bombers. Perhaps its only air victory was in the Aegean, when a fighter stalled while chasing a Z.501. The aircraft was more often relegated to second-line duties. Sometimes, with well-trained crews, it was able to attack submarines, damaging several of them (perhaps six in total) and contributing to the destruction of two others. The aircraft had no advanced detection systems, only depth charges.
Generally the aircraft's main task was search and rescue missions, and perhaps because of this it was called Mammaiut (which means "Mamma help me!" in Italian). Another theory is that because it was helpless against enemy aircraft. Even its sea capabilities were not good and often the Z.501 needed to be helped by ships. As for its flying qualities, it was too slow, unmanoeuvrable, and under-armed to put up a defence against enemy fighters. As a result many were shot down.
