The Loening M-8 was a 1910s American fighter monoplane designed by Grover Loening and built by his Loening Aeronautical Engineering Company. The order for 5000 for the United States Army Air Corps was canceled when the First World War ended.

Development

The first design by Grover Loening after he had formed his company was a two-seat braced-wing monoplane fighter the M-8. It had a fixed tail-skid landing gear and was powered by a nose-mounted Hispano-Suiza engine with a tractor propeller. The pilot and gunner had tandem open cockpits. The first aircraft was flown in 1918 and after testing, the United States Army Air Corps ordered 5,000 aircraft to be built.

Only two aircraft were delivered to the Army and one to the United States Navy, with the designation M-8-0. At the end of the war the order was canceled. The Navy ordered 46 aircraft in two variants for use as observation aircraft. The Navy also ordered six M-8-S twin-float seaplane versions. A single-seat version was developed for the Army as the Loening PW-2.
