- First flight: 1939
In preparing for the coming war, Italy pursued clearly aggressive goals, without completely hiding this fact. Having had some good practice in Ethiopia, the management of Regia Aeronautica made generally correct conclusions that it would not hurt to update the Air Force fleet. In addition to issuing new specifications, a program of quantitative and, most importantly, qualitative re-equipment was adopted in 1938. As part of this event, it was planned to commission at least 5,000 modern aircraft, the design of which was already in full swing. This relegated the needs of civil aviation to the background, but did not mean that it was completely forgotten. Possessing vast colonial territories, Italy required a modern transport aircraft with good speed and payload capacity. For this purpose, a corresponding technical specification was formulated, issued in June 1938 to several aviation companies. In addition to speed, one of the most important indicators was also flight range, since the future aircraft needed to make, among other things, postal transatlantic flights.
One of the clear favorites was the project proposed by engineer Filippo Zappata. As a basis, he took the serial bomber Z.1007bis, the design of which was made several changes. Previously, the plane did not have any military equipment or weapons; the bomb bay was dismantled, placing in its place a cabin for passengers or oversized cargo. The Piaggio P.XI R2C 40 engines, previously installed on the bomber, were replaced with Alfa Romeo 135 RC.32 with a power of 1550 hp, which were supposed to provide a speed of at least 500 km/h, with a maximum range of 2000 kg and a load of 2000 kg . To ensure the required range, the number of fuel tanks was increased, partially placing them in the wing root. The aircraft converted in this way received the designation Z.1015 and, due to its good design data, was simultaneously submitted to the 1938 competitions for transport aircraft (Z.1015) and bombers (Z.1015B). The first prototype was assembled by December 22, 1938, but it only took off on January 20 of the following year. Factory tests were carried out at the Ronchi Legionari airfield, the aircraft was piloted by Mario Stoppani. Almost immediately, major problems emerged in the operation of the power plant, which were not possible to correct until the end of 1939. Since military orders were of paramount importance at that time, the Air Force refused to conduct further tests of the Z.1015. The company's specialists tried to correct the situation by replacing the engines with less capricious Piaggio ones with three-blade propellers, but this work was done too late. After several more flights, the plane was left in the company's hangar awaiting further decisions.
So Z.1015 stood until 1942, until the commander of I° Nucleo Aerosiluranti di Gorizia, Colonel Carlo Unia, drew attention to it. After the defeat inflicted on the Italians on all fronts, there was an urgent need to replenish the considerably thinned regiments and groups of bomber aviation. The most massive bombers in 1941-1942. there were still SM.79 and Z.1007. These were reliable, but obsolete cars that needed to be replaced in the very near future. It was then that we remembered Z.1015. The aircraft was again accepted by the Air Force for comparative tests with the SM.79 and received the registration number MM.512. In test flights that took place from June 23 to July 3, 1942, the Z.1015 completely rehabilitated itself, showing a speed of 563 km/h with the same payload and range characteristics. The only major criticisms were the large weight of the aircraft and the lack of armor, which could make it easy prey for enemy air defense and fighters. Serial production of the Z.1015 was abandoned, but from the end of 1942 the aircraft was put into limited service. By the time of the armistice, it was at the disposal of the company and most likely was captured by German troops, after which traces of the only copy of Z.1015 are lost.
