Hungarian 44M Tas
The 44MTAS tank was designed both as a main battle tank and tank destroyer equpped with a75mmgun. The design was preferred over having to develop a turretless tank destroyer armed with an88mmgun. Developed in 1943, it was intended to replace the inferior Hungarian40MTuran and and43mZrinyi. Mass production would have stared in 1945 but the factory and prototype were destroyed in 1944.
