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

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. ,
