SDP 60 Gonkiewicza

Poland·Tank Destroyer·ATSPG assault

In 1960, a project for the SDP 60 Gonkiewicza heavy tank destroyer appeared in Poland. The well-armored vehicle was supposed to have good mobility. To achieve this, it was to be equipped with a small but powerful engine based on one of the early variants of the GTD-1 gas-turbine engine with a projected 1,000 h.p. Documentation on the engine was provided by the Soviet Union, which also shared materials on deep-rifled guns with its Polish colleagues, who developed their line of guns based on them. On the whole, the project was a success, but the vehicle was never built because of its high costs.
