The Tarnów Mechanical Plants are known primarily for their production of tiny arms, deck weapons or grenade launchers and anti-aircraft kits. The factory, which started production for the military in the early 1950s, which is somewhat later than its pre-war environment about COP-y roots, plays a major function in the modernization of the Armed Forces of Poland. Her products, apart from specialists, frequently known only superficially, although frequently ahead of even the military's expectations, are of greater importance than it may seem.
