2S4 2Armament


Though the crew consisted of four men, an extra five were required to operate the mortar. The 240mm mortar had a range of 9.65 km, or up to 20 km with extended range ammunition. Due to the large size of the weapon and the weight of the ammunition (130 kg for a standard projectile), it had a slow rate of fire: one round per minute. In addition to the high explosive rounds, it could fire armor-piercing, chemical and nuclear rounds. It could also fire the “Smel’chak” (“Daredevil”) laser-guided round.

Service History

The 2S4 saw action during the Soviet Union’s conflict in Afghanistan and the Global Civil War. In both conflicts, the Smel’chak projectile consistently destroyed targets quickly, precisely, and with only a few rounds. The extreme firepower per round compensated for the Tyulpan’s slow rate of fire.
