Obj. 590
A prototype of a medium tank. It was developed in the early 1960s as a part of a program for producing a brand-new medium tank. The vehicle had to have a dual-plane gun stabilizer and an autoloader in the rear recess of the turret. Work was discontinued in 1963 as the project was deemed too expensive and the future vehicle too complex to maintain and repair. No metal prototype was ever produced.
