The Messerschmitt Me 163 Komet was a German rocket-powered military interceptor used late in the Second World War. Its extraordinary climb performance contrasted with very short powered endurance and dangerous operating characteristics. Small numbers reached combat, and the aircraft had little influence on the outcome of the air war.[1][2]
Lippisch's tailless aircraft
The Komet grew from Alexander Lippisch's work on tailless research aircraft. Me 163A prototypes were tested in 1941, while the operational B-model represented a substantial redesign around a more powerful Walter rocket motor. Propulsion and fuel-system development caused repeated difficulties.[1][2]
For takeoff, the aircraft used a wheeled trolley that was released after becoming airborne. Landing took place on an extendable skid. This unusual arrangement saved conventional landing-gear weight but made landing demanding and exposed pilots to injury when the skid failed or the aircraft overturned.[1]
Intercepting bombers
Production Me 163Bs became available for operational use in 1944. The intention was to protect targets by climbing rapidly into approaching bomber formations. Its cannon could inflict heavy damage, but the closing speed left only a brief opportunity to aim and fire.[1][2]
High propellant consumption limited powered flight to a few minutes. Once that supply was exhausted, the pilot had to glide home, unable to use engine power to escape escort fighters or correct an unsuccessful landing approach.[1]
Hazards and limited results
The propellants were highly hazardous, and leaks, explosions and landing accidents threatened crews alongside enemy action. Special handling facilities also restricted where Komets could operate. Jagdgeschwader 400 was the operational formation associated with the type, but the combination of these limitations prevented its dramatic performance from becoming an effective sustained bomber defence.[1][2]
