The NC 70 Błyskawica tank destroyer was developed as an anti-armor vehicle and a means to destroy fortifications, as well as to suppress and destroy enemy artillery and infantry. The project was to use a new artillery system that ensured high initial shell velocity. The gun was to be hard-mounted in the cabin without using recoil absorbers, which decreased its complexity and cost. The power unit included two gas-turbine engines. The project existed only in blueprints.
