The Katyusha rocket launcher is a type of multiple rocket launcher developed by the Soviet Union during World War II. It is known for its ability to launch a barrage of rockets quickly, providing a powerful and overwhelming attack on enemy positions. The system typically consists of a truck-mounted frame that holds multiple rocket tubes, allowing for rapid firing. Katyusha rockets were used extensively by the Soviet Red Army and became a symbol of Soviet artillery during the war. Their effectiveness in delivering explosive payloads over a wide area made them a crucial asset in battles, contributing to the Soviet Union's military successes against the Axis powers.
