The TOS-2 (Tosochka) (, Heavy Flamethrower System) is a Russian 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.
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. The system uses the 6x6 Ural-63706-0120 all-terrain vehicle instead of the tracked armored chassis of the TOS-1A.
The TOS-2 entered service with the Central Military District on 6 January 2021.
In late May 2022, TASS reported that the system was deployed in Ukraine during the 2022 Russian invasion of Ukraine. In October 2023, the TOS-2 system was sighted in the area surrounding Kreminna, Luhansk Oblast. It was reported in August 2024 that the range of the system has been extended, up to 20 km. Supplies of a masking coating began in October 2024.
In February 2025, photos showing a destroyed TOS-2 MLRS in the Pokrovsk area were published on the internet. This represented the first confirmed loss of this system. , OSINT defense analysis website Oryx lists one TOS-2 as destroyed and one as damaged.
