RM-70 (Raketomet vzor 1970): History, Capabilities, and Global Deployment
Introduction to the RM-70
The RM-70 (Raketomet vzor 1970) is a multiple launch rocket system (MLRS) developed by Czechoslovakia during the Cold War. Introduced in 1972, it was designed as a heavier, more mobile, and faster-reloading alternative to the Soviet BM-21 Grad. Built on the robust Tatra 8×8 heavy truck chassis, the RM-70 has proven to be one of the most enduring artillery systems of the modern era.
Even today, the RM-70 and its upgraded variants remain in service worldwide, actively used in conflicts such as the Russo-Ukrainian War.
Origins and Development During the Cold War
The Need for a BM-21 Grad Alternative
While the BM-21 Grad was a revolutionary rocket artillery system for its time, Czechoslovakia sought to improve its mobility, survivability, and reload speed. The RM-70 addressed these weaknesses while keeping compatibility with 122 mm rockets.
Role of Czechoslovakia in MLRS Innovation
Czechoslovak engineers combined Soviet rocket technology with the Tatra T813 8×8 chassis, which offered exceptional off-road mobility and a unique reload system carrying an additional 40 rockets. This innovation gave the RM-70 a tactical edge on the battlefield.

RM-70 vs Other MLRS Systems
Comparison with Soviet BM-21 Grad
- RM-70 offers better mobility and reload speed.
- Both systems share 122 mm rocket compatibility.
Comparison with NATO M270 MLRS
- M270 has longer range and precision, but RM-70 is simpler, cheaper, and easier to maintain.
- RM-70 Modular bridges this gap by firing NATO 227 mm rockets.
Strategic Importance Today
The RM-70 remains relevant due to its flexibility, affordability, and modernization potential. In Ukraine, its Vampire variant has played an active role in counter-battery fire against Russian artillery.
