GRAD

The BM-21 Grad is a self-propelled 122mm multiple rocket launcher designed in the Soviet Union, first developed in the early 1960s and seeing its first combat use in 1969. The system consists of a Ural-375D 6x6 truck chassis with a bank of 40 launch tubes, powered by a water-cooled V8 180hp gasoline engine, and can fire 40 rockets in as little as 20 seconds. The system has a range of up to 30 kilometers and can deliver 720 rockets in a single volley, making it effective at shorter ranges. The BM-21 has been adapted by several countries, including China, Egypt, and North Korea, and has seen service in various conflicts. Its intended replacement in Russian service is the 9A52-4 Tornado.learn more on wikipedia
