# ISU-152BM

Role
: Assault Gun

## [General information](/md/rv/vehicles/isu-152bm.md#general-information)

Description
: The **ISU-152BM** is an Assault Gun, a Soviet prototype that paired the ISU-152 hull with the long **152.4mm BL-8** gun for improved anti-tank performance. The BM (Bolshoy Moshchnosti — high power) variant was tested but did not enter production. In-game it is a tracked vehicle weighing 46 tonnes with a crew of four — driver, gunner, commander, and loader — and a **V-2IS** diesel producing 520 horsepower for 11.3 hp/t and 35 km/h forward.
The main armament is the 152.4 mm BL-8 with OF-540 and BR-540B and a 23-second reload. The gunner uses a 2x telescope with no rangefinder; there is no secondary machine gun in the data.
