POMILIO GAMMA Italy
Early in 1918, the Pomilio concern of Turin completed the prototype of a single-seat fighter designated Gamma (the third letter of the Greek alphabet). Powered by a 200 hp SPA 6A water-cooled engine, the Gamma was a single-bay, unequal-span biplane of wooden construction. Demonstrated for an official commission, the Gamma proved both fast and manoeuvrable, but was considered to possess an inadequate climb rate. The second prototype was therefore fitted with a 250 hp Isotta-Fraschini V6 engine as the Gamma IF. The official commission disagreed on the merits of the fighter and it was not until the closing weeks of World War I that a small batch of Gamma IF fighters was ordered, but these did not enter service with the Aviazione Militare. Ottorino Pomilio and his brother settled in the USA in 1918, establishing the Pomilio Brothers Corp. The following data relate to the Gamma IF.
