Frequently Asked Questions

What is the M-21OF rocket used for?

The Soviet 122mm M-21OF rocket is a High Explosive Fragmentation (HE-FRAG) munition designed for the BM-21 Grad Multiple Rocket Launcher system, used for area suppression and engaging targets with shrapnel.

What are the key components of the M-21OF rocket shown in the video?

The video highlights the fuse assembly (like the MRV-U Fuse), the HE-FRAG warhead, the main rocket motor body, the seven-nozzle exhaust system, and the four spring-loaded folding stabilizing fins.

How is the M-21OF rocket stabilized during flight?

The M-21OF rocket is stabilized by four fins located at the rear. These fins are spring-loaded and automatically deploy outwards once the retaining wire is released, providing aerodynamic stability.

What is the role of the seven-nozzle base plate on the M-21OF rocket?

The seven-nozzle base plate directs the exhaust gases from the rocket motor. This design is characteristic of the BM-21 Grad system and contributes to the rocket's propulsion and stability during launch.
