Tula's "Scientific and Production Association "Splav" is modernizing 300mm guided and controlled rockets of the 9M55F/K and 9M544/549 families for the Smerch and Tornado-S MLRS. Engineers will improve the aeroballistic parameters of the product by reducing the cross-section of the aerodynamic fin deployment units.
According to open sources, the new 300mm URS will receive accelerating solid-propellant rocket engines with higher impulse fuel charges. The range of action in this case may increase to 180-200 km, approaching the capabilities of the 9M723-1 Iskander-M operational-tactical ballistic missiles.
NPO "Splav" is also developing a project for a guided rocket with a supersonic integrated ramjet engine with 4 extended air intake units.
If successfully implemented, the Russian Armed Forces will receive a 300mm URS, maintaining a speed of about 1000 m/s even in the terminal section of the trajectory due to the long adjustable period of fuel charge burnout. The radius of action of such a projectile may approach 300 - 330 km, which will open new horizons for 300mm rocket artillery.
Earlier www1.ru reported that the latest Yarl body armor was handed over to Russian sappers, and they passed all the resistance tests.
