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 XB-38 was the result of a modification project undertaken by Vega (a subsidiary of Lockheed) on a Boeing B-17 Flying Fortress to fit it with liquid-cooled Allison V-1710-89 V-12 engines. It was to be an improved B-17, and an alternative if the normally fitted air-cooled Wright R-1820 radial engines became scarce. Completing the ...
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 ...

Both were equipped with Packard Merlin V-1650-23 and −25 engines. The third experimental aircraft, designated XP-82A, had two Allison V-1710-119 engines. It was accepted in October 1945. There is no evidence that the XP-82A was ever actually flown, due to problems with the Allison engines. The fourth XP-82A prototype (44-83889) was canceled ...
It was to test the feasibility of using liquid-cooled Allison V-1710-89 engines, if the Wright R-1820 engine became scarce. Completing the modifications took less than a year, and the XB-38 made its first flight on 19 May 1943.
Both the Rolls-Royce/Packard Merlin V-1650 and the Allison V-1710 were in production, with similar power and better Power/Weight Ratios. The V-1710 was 1395 lbs, 385 pounds lighter than I-1430 with a power-to-weight ratio of 1.05. The Merlin V-1650 weighed in at 1640, 25 pounds more than the smaller and unproven Continental with about the same ...
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 ...
