Rocket artillery refers to a type of artillery that uses rockets instead of traditional shells to deliver explosive payloads. This system is designed for long-range bombardment and can launch multiple rockets in a short period, making it effective for saturating a target area. Notable examples include the Katyusha rockets used during World War II. The primary advantage of rocket artillery is its ability to deliver a large volume of fire quickly, which can overwhelm enemy defenses. Modern systems, such as the HIMARS (High Mobility Artillery Rocket System), enhance mobility and precision, allowing for rapid deployment and targeting in various combat scenarios.
