Role

The main 152 mm divisional self-propelled howitzer of the Soviet Army through the 1970s–1980s, developed under the “Object 303” designation at Uraltransmash to replace the towed D-1 and ML-20. Still in service with the Russian Army, gradually being replaced by the newer 2S19 “Msta-S” and 2S35 “Koalitsiya-SV”. The turret carries the 152 mm rifled 2A33 howitzer — a derivative of the towed D-22 — with semi-automatic loading in the horizontal barrel position. The bespoke tracked chassis (Object 303) is unified with the SU-100P and uses an engine-forward / fighting compartment-aft layout, allowing a large rear hatch for mechanised resupply directly from the ground. The M2 is a 2006 upgrade: “Uspekh” automated fire-control, support for the “Krasnopol” and “Santimetr” guided shells, and modernised sights and radios.
