The Messerschmitt Me 163 Komet was a German rocket-powered fighter aircraft developed during World War II. It was notable for being the world's first operational rocket-powered fighter, designed to intercept Allied bombers. The Komet had a unique, streamlined shape and was powered by a liquid-fueled rocket engine, allowing it to achieve high speeds. The aircraft was introduced in 1944 and had a short operational history due to its complex technology and limited production. Despite its impressive speed, the Me 163 faced challenges such as a high accident rate and vulnerability during takeoff and landing, which ultimately limited its effectiveness in combat.
