Marton X/V

The concept of a cantilever monoplane pusher-puller fighter with twin tail units on booms was retaken by Hungarian engineers at the end of 1942.
As the locally-built fighter, the Weiss WM-23 'Ezüst Nyíl' proved to be obsolete, the Royal Hungarian Air Force centered their attention on Martons' project.
Externally it resembled the original Fokker D.XXIII, the first fighter flying with such configuration, however it was shaped more aerodynamically. The prototype was built along 1943 and was powered by two Daimler-Benz DB.605 engines, one in pusher and another one in puller configuration yielding each of them 1475hp of power. Expected maximum speed was of, at least 580km/h (360,40mph) at some altittude that haven't been found.
It was going to be armed with two 20mm guns plus another two 12.7mm machine guns, the late ones placed in the nose over the engine and the first ones placed in the wings, however the prototype never had armament installed.
The sole prototype was destroyed in an US air raid on 13th April 1944, so the programme was abandoned and the Royal Hungarian Air Force decided that it was best to concentrate on the already adquired Messerschmitt Bf.109G and Messerschmitt Me.210.
