he Fokker D.XXIII was designed by Marius Beeling as a twin-engined single-seat aircraft.
To overcome the problems of asymmetric flight it had a tractor engine at the front and a pusher engine at the rear.
The D.XXIII was a cantilever monoplane with the twin tail units on booms.
The pilot had an enclosed cockpit in between the tractor and pusher engines and it had a retractable tricycle landing gear.

. Only one aircraft was flown before the country was invaded by the Germans in May 1940
