The TOS-2 Tosochka is Russia's wheeled successor to the tracked TOS-1A heavy flamethrower system, using 220 mm thermobaric and incendiary rockets from an 18-tube launcher on a Ural 6x6 truck. Public Russian and U.S. Army reporting emphasizes the integrated crane, automated fire-control equipment, and wheeled chassis as the main mobility and reload changes, while conflict reporting has documented Russian TOS-2 employment and later Ukrainian strikes against the rare system during the 2014 Russia-Ukraine War.
Russian forces fielded the TOS-2 in Ukraine for thermobaric rocket fire; reporting based on a Russian Ministry of Defense confirmation describes NRBC-unit employment against Ukrainian fortifications with extended-range projectiles, and Ukrainian reporting later described FPV-drone strikes against a Russian TOS-2.
Role detailsThe TOS-2 record sits in the Russian heavy-flamethrower family: TOS-1A is the tracked predecessor, while TOS-2 moves the launcher to a wheeled truck chassis with an integrated crane and updated fire-control equipment.
| Variant | Configuration | Designation notes |
|---|---|---|
 | Tracked predecessor in the heavy-flamethrower family | TASS and U.S. Army OE reporting describe TOS-2 as a further development or successor to the earlier TOS-1A, replacing the tank chassis with a wheeled truck and adding an integrated loading crane.

TOS-2 keeps the 220 mm heavy-flamethrower mission associated with TOS-1A but changes the launcher architecture. The key public distinction is not a new general artillery role; it is the move from a tracked launcher and separate transporter-loader pattern toward a wheeled truck with its own loading crane and updated fire-control equipment.
