The ACAZ C.2, Ateliers de Construction Aeronautique de Zeebruge, was a prototype Belgian biplane fighter aircraft built in the 1920s.
Built entirely of Duralumin metal, it was an advanced design at the time of its first flight in 1926, but although evaluated by the Belgian Air Force, no orders were placed. Of conventional biplane construction, the C.2, registered as O-BAFX, later OO-AFX, incorporated one unique feature - all four of its wings were identical and interchangeable. The aircraft also included space for cameras, allowing it to be used for photo-reconnaissance.
Flown early in 1926 and evaluated by the Belgian Aéronautique Militaire, the C.2 tandem two-seat fighter-reconnaissance biplane was built by the Ateliers de Construction Aéronautique de Zeebrugge (A.C.A.Z.). Of all-metal construction, the C.2 was powered by a 450 hp Hispano-Suiza 12Ha 12-cylinder liquid-cooled engine, and an interesting feature was the interchangeability of all four main wing panels. The pilot and observer/gunner were seated in tandem and armament consisted of a single fixed forward-firing synchronized 7.7-mm Vickers machine gun and two Lewis guns of similar caliber on a flexible mount. No production order for the C.2 was placed by the Aéronautique Militaire, and, on 03/09/1928, the sole prototype was employed for an attempt to fly to the Belgian Congo, this ending in a forced landing in France. The Aircraft was written off on 01/25/1933.
