The Allison V-1710 aircraft engine designed and produced by the Allison Engine Company was the only US-developed V-12 liquid-cooled engine to see service during World War II. Versions with a turbocharger gave excellent performance at high altitude in the twin-engined Lockheed P-38 Lightning , and turbo-superchargers were fitted to experimental ...
The very first V-1710 was purchased by the U.S. Navy as their GV-1710-2, and appears to have had an Allison serial of number 1, suggesting that they restarted numbering for the V-1710. The first V-1710 engine purchased by the USAAC was AAC 33-42, Allison Serial No. 2, the XV-1710-1, while Serial Nos. 3, 4, 5 were V-1710-4 engines for U.S. Navy ...
TRADCOM offered funding to create the TC-264 Sno-Buggy, which had eight huge 120-inch (3.0 m) rubber tires, arranged in pairs and driven by four motors powered by a single Allison V-1710 engine running on butane. The resulting vehicle has an enormous amount of tire area to vehicle weight, allowing it to float on the tundra and snow.
They were equipped with two counter-rotating Allison liquid-cooled engines, V-1710-143 and V-1710-145. The first four F-82Es were redesignated as F-82As and were allocated for engine testing. After production delays by engine problems and additional testing, F-82Es entered operational service in May 1948.
Allison V-1710 Shortly after the sale to General Motors on April 1, 1929, Allison engineers began work on a 12-cylinder engine to replace the aging Liberty engines. The result was the V1710 12-cylinder aircraft engine and it made the company, renamed to the Allison Division of GM in 1934, [ 3 ] also known as the Allison Engine Company , a major ...
The P-51A used the new Allison V-1710-81 engine, a development of the V-1710-39, driving a 10 ft 9 in (3.28 m)-diameter three-bladed Curtiss-Electric propeller. The armament was changed to four .50 in (12.7 mm) Browning machine guns, two in each wing, with a maximum of 350 rounds per gun (rpg) for the inboard guns and 280 rpg for the outboard.

RP-63A/C "Pinball" Target aircraft with five modified from P-63As and 95 modified on production lines; in 1948, surviving RP-63A aircraft were redesignated QF-63A. A further 200 production RP-63C aircraft were modified ...
V12 engines reached their apogee during World War II with engines such as the British Rolls-Royce Merlin and Rolls-Royce Griffon, the Soviet Klimov VK-107 and Mikulin AM-38, the American Allison V-1710, and the German Daimler-Benz DB 600 and Junkers Jumo. These engines generated about 750 kW (1,000 hp) at the beginning of the war and over 1,100 ...
