122mm Grad

In the defense industry, 122 Grad refers to the 122mm BM-21 "Grad" (Russian for "Hail") Multiple Rocket Launcher System (MLRS) and the specific unguided rockets it fires.

​

It is arguably the most widely used rocket artillery system in the world, serving as the global benchmark for area-saturation weaponry.

​

Key Technical Specifications

The "Grad" is designed to blanket a large area with high-explosive power in a very short time.

• Caliber: 122 mm

• Rocket Length: ~2.87 meters

• Rocket Weight: ~66 kg

• Salvo Capacity: 40 tubes (standard truck-mounted launcher)

• Rate of Fire: Can fire a full 40-round salvo in 20 seconds.

• Standard Range: ~20 km (traditional 9M22U rockets).

• Modern Range: Up to 40–45 km (with upgraded motors

 

Operational Role: "Area Saturation"

Unlike a missile, a Grad rocket is unguided. It is not meant for "pinpoint" accuracy against a single car or room. Instead, it is used for:

• Suppressing infantry in open terrain.

• Destroying unarmored vehicle convoys.

• Artillery preparation before a ground assault.

• Counter-battery fire (striking enemy artillery positions)
