A rocket launcher is a device designed to launch rockets into the air. These can be used for various purposes, including military operations, space exploration, and scientific research. Rocket launchers can be mobile or stationary and are often equipped with guidance systems to ensure accuracy. In military contexts, rocket launchers are used to fire projectiles at enemy targets. They can vary in size and range, from portable systems like the RPG-7 to larger systems like the HIMARS. In space exploration, rocket launchers, such as the SpaceX Falcon 9, are crucial for sending satellites and spacecraft into orbit.
