Role

A Soviet 152 mm long-range self-propelled gun at the corps level, developed at Uraltransmash under the “Object 307” designation as a counterpart to the American 175 mm M107. Adopted in 1976. It mounts the 2A37 rifled gun with a 47-calibre barrel (7.14 m) — at the time of its introduction the longest-ranged among production self-propelled guns in the world: up to 28.5 km with the standard HE 3OF29 (47 kg) and up to 33 km with the rocket-assisted 3OF30. It can fire the 3VB8 tactical nuclear round. The gun is mounted on a pedestal behind an open fighting compartment without a turret; the crew works outside the vehicle. The “Object 307” chassis is original-tracked and shares components with the 2K11 “Krug” SAM system and the 2S4 “Tyulpan” mortar. Ammunition stowage is 30 rounds, with separate-loading projectile and charge. Intended for counter-battery fire and engagement of tactical missile systems and rear-area targets. Produced at Uraltransmash from 1977 to 1991 (~2 000 units). Used in Afghanistan (1979–1989), Chechnya (1994–1996), Syria (since 2017) and in the Russian-Ukrainian conflict. In the 1990s Finland purchased nine examples from Ukraine under the designation 152 TELAK 91.
