The TOS-2 (Tosochka) (, Heavy Flamethrower System) is a Soviet multiple rocket launcher capable of using thermobaric warheads, mounted on a 3-axle truck chassis. TOS-2 was designed to attack enemy fortified positions and lightly armoured vehicles and transports, in open terrain in particular. History On 12 January 2018, it was announced that NPO Splav was working on a prototype of a next generation TOS-1 system for preliminary tests. The system with improved tactical and technical characteristics will be made on a wheeled chassis. The new TOS-2 (Tosochka) system was first unveiled during the 2020 Moscow Victory Day Parade, and further showcased during the Kavkaz-2020 drills in September 2020. It is equipped with a more powerful TBS-M3 rocket and its own crane. It has also an increased range and is protected from precision weapons.
