Curtiss V-1570 Conqueror By Note: This item is currently in storage. The Curtiss Aeroplane and Engine Co. began producing its famous Conqueror engine in 1926. Although similar in general principles of design to the earlier Curtiss D-12 engine, the Conqueror was larger and more powerful. Originally rated at 600 hp, the engine's performance in several later versions was improved to 675 hp. In the late 1920s and early 1930s, the V-1570 Conqueror was selected to power the Curtiss P-6 series "Hawk" aircraft as well as various other Air Corps types including the A-8, B-2, B-7, O-25 and P-16. After 1935, the Conqueror was superseded by more advanced liquid-cooled engines. TECHNICAL NOTES: Model: V-1570-59 Type: 12-cylinder, liquid-cooled, Vee Displacement: 1,570 cu.in.
