The ZiŁ-157 is a Russian truck produced from 1958 to 1992 at the Likhachev Plant in Moscow. In total, approximately 800,000 copies were produced. Our vehicle – a tractor unit – comes from 1987. The ZiŁ-157CS cars together with the PR-11B semi-trailer formed the STZ set (Transport and Loading Vehicles) and were used to transport W-755 missiles and load them onto the launchers of the S-75M Volkhov anti-aircraft missile system. The 25th Air Defense Missile Squadron in Dąbrówka, which was stationed on what are now the museum grounds from 1963 to 2001, had 7 such STZs in stock.
