After protracted delays during taxi-ing tests, and modifications to the vertical surfaces and tailwheel, the Arsenal-
Delanne 10 finally flew for the first time in October 1941. The undercarriage was successfully retracted on the
second flight, and some fifteen test flights were made from Villacoublay during which six hours in the air were
logged. After the completion of these trials, 12 or 14 July 1943,  the fighter was ferried to a German experimental
centre (Oppitz) for further tests, tested at DFS led by Felix Kracht, but its subsequent history is unknown
The Arsenal-Delanne 10-C2 two-seat fighter designed by Maurice Delanne and built by the Arsenal de l'Aeronautique was of so-called Nenadovich biplane configuration, the tandem-mounted wings providing a continuous slot effect and offering exceptional CG travel.The fighter was of all metal stressed-skin construction, which used a sandwich technique, with a smooth dural skin welded to a corrugated sheet. Pilot and gunner sat in tandem under a single canopy at the rear of the fuselage, which was level with the rear wing, which carried twin tailplanes. This arrangement gave the gunner a clear field of fire for his planned armament of two 7.5 mm machine guns, which was to be supplemented by a 20 mm cannon firing through the propellor hub and two more machine guns in the wing. The aircraft was fitted with a retractable tailwheel undercarriage
The Arsenal-Delanne 10-C2 prototype was virtually complete at Villacoublay when German forces occupied the factory in June 1940, work on the aircraft continuing in a desultory fashion . The intended armament comprised an engine-mounted 20mm Hispano-Suiza cannon, two wing-mounted 7.5mm MAC 1934 machine guns and two further 7.5mm weapons on a flexible mounting.
