This is one of the more interesting and less known Soviet contraptions – the 2S15 “Norov” tank destroyer.
Basically it’s a product of the same school of thought as the 2S14 Zhalo-S – the idea was to put a powerful gun on a mass-produced light chassis to create a cheap and powerful tank destroyer. In this case the chassis is that of the 2S1 Gvozdika self-propelled gun (although as you can see, it has been modified) and the gun is a 100mm… something. Type unknown. The gun would be installed in a brand new turret equipped with an automatic radar-controlled fire control system. The main developer was the Yurga Machine Plant, the developer of the FCS was the “Strela” design bureau in Tula. A prototype was supposed to be built by the “Arsenal” plant (not sure which one, there were apparently more facilities of the same name).
The decision to design the vehicle was taken on 17.5.1976. The vehicle was supposed to be produced from 1980 onwards but the plant didn’t meet the deadline. The deadline for prototype construction shifted first to 1981 and then to 1983, when the actual testing started. At that point, however, news reached the Soviets about modern western MBT variants, against which 100mm guns were too weak. The project was declared obsolete and cancelled in 1985.
Not much else is known save for the fact that the armor was likely very light (Gvozdika level – some 15mm to 20mm of steel) and the vehicle was generally quite fast (maximum speed of 60 km/h, 300hp YAMZ-238 engine, weight probably around 15 tons).
