As reported on Russian social media on December 12, 2024, the Russian company NPO Splav launched modernization programs for the 300mm guided rocket systems used by the BM-30 Smerch and Tornado-S multiple launch rocket systems (MLRS). These upgrades aim to improve the range and accuracy of these systems, potentially extending their operational ranges to 180–200 kilometers while refining their flight characteristics. New designs, including a supersonic ramjet-guided missile, may align the capabilities of the upgraded rockets more closely with those of the Iskander-M tactical ballistic missile.
The Tula-based NPO Splav is implementing modernization programs to enhance the capabilities of its 300mm corrected and guided rocket projectiles, specifically the 9M55F/K and 9M544/549 families, used in the Smerch and Tornado-S multiple launch rocket systems (MLRS). This includes adjustments to the aeroballistic properties of the projectiles, such as reducing the cross-sections of aerodynamic rudder units and minimizing surface protrusions, aimed at improving range and flight characteristics. Updated solid-propellant rocket motors with higher-impulse fuel charges are being introduced, potentially extending the range of these systems to 180–200 kilometers, approaching the operational performance of the Iskander-M tactical ballistic missile.
In addition to these modifications, NPO Splav is developing a guided missile with an integral rocket-ramjet engine and retractable air intakes. This design is expected to maintain a velocity of approximately 1,000 m/s during the terminal flight phase and achieve ranges of up to 300–330 kilometers. If successful, it would significantly enhance the long-range precision strike capabilities of 300mm rocket artillery systems.
