OVERVIEW: The 9M521 is a 122mm unguided high-explosive (HE) fragmentation artillery rocket designed for use with the Tornado-G multiple launch rocket system. It features extended range and enhanced lethality compared to earlier Grad-series munitions.

DETAILS: The 9M521 was developed by Russia to modernize and extend the effectiveness of 122mm artillery systems. It employs a solid-propellant motor and fin stabilization to reach targets up to 40 km away. The rocket is equipped with a high-explosive fragmentation warhead with a pre-fragmented casing and a point-detonating fuze, designed to saturate target areas with lethal steel fragments upon impact. The design improves reliability and lethality while maintaining full backward compatibility with legacy platforms.

Compared to legacy rockets like the 9M22U, the 9M521 offers increased accuracy, longer range, and a higher fragment yield. It is optimized for use with Tornado-G’s automated fire control and launch systems. The improved aerodynamic profile and internal design allow more efficient trajectory stability and predictable dispersion.

The 9M521 is launched from modular pods mounted on Tornado-G vehicles, which allow faster reloading and coordinated strikes. It is intended for wide-area suppression, interdiction fire, and pre-attack bombardment against troops, artillery positions, and light fortifications.
