BM-21

Displayed as a static open-air exhibit in the small Hungarian town of Kecel, this BM-21 Grad is a Soviet-designed 122 mm multiple rocket launcher that entered mass production in 1963. The name 'Grad' — Russian for 'hail' — refers to the system's characteristic saturation fire pattern; it became one of the most widely used artillery systems of the Warsaw Pact. The exhibit offers a close-up look at Cold War-era Soviet military hardware, with no visitor infrastructure beyond the vehicle itself.
