The Aeromarine PG-1 was a single-seat Pursuit and Ground Attack (PG) biplane developed by the Engineering Division of the United States Army and manufactured by the Aeromarine Plane and Motor Co. of Keyport, New Jersey. A biplane is a Fixed-wing aircraft with two main Wings The first powered heavier-than-air Aircraft, the Wright brothers' Wright Flyer The United States Army is a military organization whose primary mission is to "provide necessary forces and capabilities. Aeromarine Plane and Motor Company was an early aircraft manufacturer founded by Inglis Upperçu at Keyport New Jersey in 1908. Keyport is a Borough in Monmouth County, New Jersey, United States.
The PG-1 was intended to fulfil both ground strafing and aerial defence roles, and was armed with a single 0. 5 in (12. 7 mm) machine gun as well as a 37 mm Baldwin cannon firing through the propeller hub; the cockpit had ¼-in (6.

The wings were dissimilar, with a narrow-chord lower plane lacking the ailerons present on the wider top surface. For the band with a similar name see The Ailerons Ailerons are hinged control surfaces attached to the Trailing edge of the Wing of a Fixed-wing The upper wing was mounted close to the top of the fuselage with a cut-away forward section to accommodate the cockpit, and attached to the lower plane via V-type struts.
Power was to have been provided by the eight-cylinder, water-cooled 330 hp Wright K-2 engine but the first two prototypes were fitted with 346 hp Packard 1A-1116 units due to delays in clearing the K-2 for flight testing. The Curtiss-Wright Corporation ( was once a leading Aircraft manufacturer of the United States, but has since become a component manufacturer specializing in A reciprocating engine, also often known as a piston engine, is a Heat engine that uses one or more reciprocating Pistons to convert A third prototype was also built and testing was eventually carried out using both the K-2 and Packard's 1A-1237 at McCook Field. McCook Field was an airfield and aviation experimentation station operated by the Aviation Section U Prototype aircraft suffered disappointing performance, high levels of vibration and poor visibility, and development was abandoned in 1922.
