The Pfalz Dr.I was a German fighter prototype of World War I. Official interest in the potential of the triplane configuration for single-seat fighters prompted Pfalz to develop the Dr.I. It underwent initial testing in October 1917, and an initial batch of 10 aircraft were shipped to the Front and arrived in April 1918.
The Villiers II was a French two-seat fighter aircraft of the 1920s intended for operation from the Aircraft carrier Béarn of the French Navy. It was a single-engined tractor biplane with a waterproof hull in the form of a flying boat to allow the aircraft to be safely landed on water in an emergency. Two prototypes and 30 production aircraft were built, the type serving briefly with the French Navy, although never operated from an aircraft carrier.
The Macchi M.26 was an Italian flying boat fighter prototype of 1924 designed and manufactured by Macchi.

The Macchi M.6 was an Italian flying boat fighter prototype of 1917.
The Kawasaki Ki-64 was a one-off prototype of an experimental heavy, single seat, fighter. It had two unusual design features. First; it had two Kawasaki Ha-40 engines in tandem; one in the aircraft nose, the other behind the cockpit, both being connected by a drive shaft. This combination drove two, three-bladed, contra-rotating propellors. The second feature was the use of the wing surface as a radiator for the water-cooled engines. The aircraft first flew in December 1943. During the fifth flight, the rear engine caught fire; and while the aircraft made an emergency landing, it was damaged. The aircraft was subsequently abandoned in mid-1944 in favour of more promising projects. The airframe survived the war, and parts of the unique cooling system were sent to Wright Field for examination.
The Bernard H.52 was a French floatplane fighter aircraft of the 1930s. It was a single engine, single-seat monoplane built in the hope of being selected by the French Navy. Two prototypes were built, but no production followed.
