TOS-1A Solntsepyok

Russia's T-72-based 220 mm heavy flamethrower system — a short-range thermobaric rocket launcher that turns field fortifications into deathtraps, and one of the most destructively hunted vehicles in the war in Ukraine.

Overview

The TOS-1A Solntsepyok (Object 634B / BM-1) is a Russian self-propelled multiple rocket launcher designed to destroy dug-in infantry, fortifications and light armour at short range with thermobaric and incendiary rockets. Operated by Russia’s NBC Protection Troops rather than the artillery branch, it is classified as a “heavy flamethrower system” and has been exported to several Middle Eastern, North African, Central Asian and Caucasian states. Based on the T-72 main battle tank chassis, the vehicle combines tank-level protection with a 24-tube 220 mm launcher capable of saturating up to 40,000 m² with a single salvo GlobalSecurity. Since Russia’s full-scale invasion of Ukraine in 2022, the Solntsepyok’s extreme close-range employment has made it a priority target for Ukrainian FPV drones, ATGMs and artillery, with over two dozen confirmed destroyed and many more damaged or captured.
