About this vehicle

The SDP wz 66 Grom, a tank destroyer from the late 1950s to early 1960s, was designed taking into account Soviet experience of developing similar vehicles. The armor was meant to withstand attacks from existing and potential NATO tanks, and a gas-turbine engine was planned to increase mobility. As armament, several types of guns were considered, including so-called deep-rifled ones. It was not possible to implement some of the ideas due to the technological restrictions of the time. All of the concepts went no further than blueprints.
