Messerschmitt Me 163B Komet

The story behind the display

Its speed made interception difficult, but short flight time, limited armament opportunities, hazardous fuel, and vulnerable landing procedures restricted combat value. The aircraft is a vivid case of extreme performance achieved at the expense of flexibility, safety, and operational sustainability.

History & service

The Me 163 was the end result of a long line of tailless research aircraft designed by Dr. Alexander Lippisch. The first Me 163A prototypes were tested in 1941, but powered flight testing of the more advanced Me 163B was delayed until August 1943 due to engine and fuel problems. Although the Komet's rocket engine gave it a exceptional climb rate, range was severely limited by its high fuel consumption.

Furthermore, the fuels used were extremely hazardous and sometimes exploded without warning, killing a number of pilots.

Production Me 163Bs were not ready for operational use until July 1944. The Luftwaffe planned to have small units of Komets dispersed to intercept Allied bomber formations, but only 279 Me 163Bs were delivered by the end of the war. The sole operational Komet group, JG 400, scored nine kills while losing 14 of its own aircraft.

This Me 163B (S/N 191095) may have been sabotaged while under construction, perhaps by the forced laborers building it in Germany. A small stone was wedged between the fuselage fuel tank and a supporting strap (which could have eventually caused a dangerous fuel leak), and there was contaminated glue in the wing structure (which could have caused a failure of the wing in flight).

Inside the aircraft's skin are these words, perhaps written by a defiant French laborer: "Manufacture Ferme" means "Plant Closed." "Mon coeur est en chomage" translated directly means "My heart is not occupied" (as opposed to France being occupied by the Germans).

The aircraft on display was owned and restored by the Canadian National Aviation Museum and acquired by the National Museum of the U.S. Air Force in 1999.

Aircraft change the battlefield

In the First World War, aircraft became valuable because they could see beyond the front line. Reconnaissance and artillery observation affected decisions on the ground. Once that information mattered, opposing forces had reason to attack the aircraft gathering it. Fighters, defensive armament, and increasingly specialized missions developed around this contest over observation and freedom of movement.

The aircraft were fragile by later standards, but their crews worked inside a rapidly expanding military system. Training, maintenance, replacement aircraft, photography, communications, and weather reporting supported each sortie. Improvements in engines and armament changed tactics, while the pressures of combat exposed weaknesses that might have taken much longer to discover in peacetime.

Personal stories should be read alongside those systems. A uniform or a named aircraft connects the war to an individual, but the individual depended on many others and operated under constraints that skill could not eliminate. Aircraft from opposing sides show how designers answered similar problems in different ways. The later military collections in Dayton and at Udvar-Hazy reveal what endured: the need to gather information, protect friendly forces, move people and supplies, and coordinate action across distance. The scale changed enormously; the relationship between an aircraft's design and the job it had to perform remained fundamental.
