The Messerschmitt Me 163 Komet was designed by Dr. Alexander Lippisch and Helmuth Walter.1,2,3 Walter developed the engine and Lippisch designed the plane.3

The design was based on earlier work on the DFS 194 in 1938.2 It was done by the German Research Institute for Sailplanes.2 A Walter HWK R.I motor (600 lb / 2.7kN) was added.2

The first work on the design was started on January 2, 1939, in Ausburg.3


The Walter RII-203 rocket engine got its power by combining two fuels, T-Stoff (hydrogen peroxide) and Z-Stoff.1

The Walter 109-509A rocket engine got its power by combining T-Stoff (hydrogen peroxide) and C-Stoff (hydrazine hydrate, methyl alcohol, and water).1,2

There were many accidents with the Me 163 caused by the hazardous fuel mixture.1

Trolley and Skid

The Me 163 would initially take off with an attached trolley, but it was jettisoned after takeoff.1,2 Then to land the Me 163 would land on a skid.1,2 If there was any fuel left the landing could mix the remaining fuel and cause an explosion.2


Due to the Me 163s high speed, there was little time for a pilot to shoot at a bomber.1 An upward firing 50 mm shell was developed that with a sensor would detect a bomber overhead on the Me 163's flyby and shoot the shells at the bomber.1

Under wing rockets were also used.1


The DFS 194 was first flown in 1940.2

In the spring of 1941 the Me 163 was first tested as a glider.1 A Messerschmitt Bf 110 towed the Me 163.3

Powered flights of the Me 163V1 commenced in the summer of 1941.1,2 An engine was added and on August 13, 1941, at Peenemünde, flight were conducted.3 On October 2, 1941, a speed of 623.8 mph / 1004.5 kph / Mach 0.843 was reached.1,2,3

Wolfgang Späte flew the first rocket powered Messerschmitt Me 163 on May 13, 1944, over Bad Zwischenahn.3

The Me 263 first flew in March 1945.2


The Me 163B first flew on February 213 / June 23, 1943.2,3

JG 400

Outside of Brandis in June 1944, the I/JG 400 were equipped with the Me 163B-1a.1

On July 28, 1944, Me 163s first attacked Allied bombers near Merseburg.3 On August 16, 1944, they were first used against B-17 Flying Fortresses.1,2

Only nine confirmed victories were credited to the Me 163.1

Heavy Losses

95% of the Me 163 loses were due to landing accidents or fires in the air.2


Mitsubishi developed the J8M1 Shusui (Sword stroke) for the Japanese.2 It was a copy of the Me 163B.2 It flew in July 1945 but the prototype was destroyed.2 There were 10 J8M1s under construction but they were abandoned.2
