The Aeromarine PG-1 was an American single-seat pursuit (fighter) and ground attack (PG) biplane developed by the Engineering Division of the United States Army and manufactured by the Aeromarine Plane and Motor Co.
The PG-1 was intended to fulfill both ground strafing and aerial defense roles, the contract for construction was won by Aeromarine in May 1921. [1]
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 1⁄4-inch (6.35 mm) armour. The wings were dissimilar, with a wide-chord upper wing with ailerons, and a closely spaced narrow-chord lower plane with dihedral that placed the tips close to the upper 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. [1]
Power was to have been provided by the eight-cylinder, water-cooled 330 hp (250 kW) Wright K-2 engine but the first two prototypes were fitted with 346 hp (258 kW) Packard 1A-1116 units due to delays in clearing the K-2 for flight testing. [1] A third prototype was also built and testing was eventually carried out using both the K-2 and Packard 1A-1237 at McCook Field. [1] Prototype aircraft suffered disappointing performance, high levels of vibration and poor visibility. The aircraft had a tendency to spin when stalled. [2] Development was abandoned in 1922. [1]

Armament
The Consolidated P-30 (PB-2) was a 1930s United States two-seat fighter aircraft. An attack version called the A-11 was also built, along with two Y1P-25 prototypes and YP-27, Y1P-28, and XP-33 proposals. The P-30 is significant for being the first fighter in United States Army Air Corps service to have retractable landing gear, an enclosed and heated cockpit for the pilot, and an exhaust-driven turbo-supercharger for altitude operation.
The Albatros D.XI was a German single-seat fighter biplane first flown in February 1918. It was the first Albatros fighter to use a rotary engine, in the form of the 120 kW (160 hp) Siemens-Halske Sh.III, and also featured a new wing construction with diagonal struts from the fuselage replacing traditional wire bracing.
The Aeromarine AS was a seaplane fighter aircraft evaluated by the US Navy in the early 1920s.
The LUSAC-11 was an early American two-seat fighter aircraft. It was a French design, commissioned and built in the United States during World War I and ordered in large numbers by the United States Army Air Corps, but these were cancelled at the end of the war, and only 30 were built. The type was used for experimental purposes, setting several altitude records during the 1920s.
The Bristol Type 6 T.T.A was a British two-seat, twin-engine biplane, designed in 1915 as a defence fighter. Two prototypes were built, but the T.T.A. did not go into production.
The Engineering Division TP-1 was a two-seat biplane fighter designed by Alfred V. Verville and Virginius E. Clark at the United States Army Air Corps Engineering Division. A second aircraft was completed as an observation biplane and designated the Engineering Division XCO-5.
The Hanriot HD.6 was a French two-seat fighter aircraft prototype, built towards the end of World War I though not flown until after the armistice with Germany. A biplane with an unusually narrow gap between upper and lower wings, powered by a single water-cooled radial engine, it did not enter production.
The Pfalz D.VI was a German sesquiplane fighter aircraft from World War I. It was not put into production.
The Loire-Nieuport 161 was a single-seat, single-engine, all-metal, low-wing monoplane fighter designed and built in France in 1935 to compete for a government contract. Accidents delayed its development and only three prototypes were completed.
The Wibault Wib 1, Wib C1 or, later, Wib 1 C1 was a French World War I single seat, single engine fighter aircraft prototype. Flown near the end of the war, it was not selected for production.
The Wibault 12 Sirocco or Wib 12 Sirocco was a two-seat, parasol wing fighter aircraft designed and built in France in the 1920s. Three fighter prototypes were completed, one for the RAF and two Army co-operation variants. There was no series production.
The Hanriot HD.5 was a French two-seat fighter aircraft prototype, built towards the end of World War I. A single-engine biplane with an unusually narrow gap between the upper and lower wings, it did not enter production.
The Hanriot HD.20 was a French single seat shipboard fighter aircraft prototype completed in 1923. Only one was built.
The Hanriot H.31 was a single engine, single seat French biplane fighter aircraft built in 1925 to compete in a government programme. It was not successful and only one prototype was completed.
The Levy Biche LB.2 was a single seat French sesquiplane fighter aircraft designed to be used from aircraft carriers. With a watertight fuselage, jettisonable wheeled undercarriage and small under-wing floats, it could survive emergency sea touchdowns; it could also be fitted with seaplane type floats.
The LFG Roland D.XV was a World War I German single seat fighter aircraft, ordered as a test-bed for engine comparisons. It was distinguished from earlier Roland biplane designs by the elimination of flying wires. Two later aircraft, also called LFG Roland D.XV, were completely different designs with slab sided fuselages.
The LFG Roland D.XVI, initially designated the LFG Roland E.I, was a single-seat, single-engine, parasol wing German fighter aircraft flown close to the end of World War I. Only two were built.
The Schütte-Lanz D.VII was a single engine, biplane fighter aircraft designed and built in Germany towards the end of World War I.
The Caudron 02 was a French high altitude single seat fighter that was flown in November 1917.
The LVG D.IV was a German fighter plane built by LVG in World War I.
