The Me 163's fuel lasted roughly 8 minutes
The Messerschmitt Me 163 Komet was a rocket-powered interceptor aircraft developed by Germany during World War II. It was the first and only tailless rocket-powered interceptor to see operational service. The Me 163 had a distinctive appearance, with sweptback wings and no tail, and was capable of incredible speed, reportedly reaching 623.8 mph in 1941. This speed came at a cost, however, as the Me 163's fuel supply only lasted for a very limited time.
The Me 163's fuel lasted for approximately 8 minutes of powered flight. This extremely limited fuel supply meant that the aircraft had a very short range and could only engage in combat for a brief period before having to glide back to base. The high speed of the aircraft, combined with the slow rate of fire and short range of its cannons, made effective gunnery difficult, and as a result, Me 163 pilots recorded relatively few kills.
The Me 163's fuel system used a volatile mixture of T-Stoff (80% hydrogen peroxide and 20% water) and C-Stoff (hydrazine hydrate, methyl alcohol, and water). This fuel mixture provided a maximum thrust of 1,500 kg (3,300 lb.), giving the aircraft its remarkable climb rate. However, the fuel was also highly corrosive and hazardous to humans, contributing to the high loss rate of the aircraft during testing and training flights.
Despite its technological advancements, the Me 163 had little impact on the outcome of World War II. Its development and deployment were plagued by challenges, including difficulties with its propulsion system and landing gear. The Me 163's fuel efficiency was also a concern, with its high fuel consumption posing design difficulties. Ultimately, the Me 163's limited fuel supply and range hindered its effectiveness as a weapon, and it saw limited combat due to the sustained advance of Allied powers into Germany.

It used a volatile fuel mixture of T-Stoff and C-Stoff
The Messerschmitt Me 163 Komet was a rocket-powered interceptor aircraft developed in Nazi Germany during World War II. It was a significant technological achievement, but its operational impact was limited. The Me 163 had a fuel capacity that allowed for only eight minutes of powered flight. Its propulsion system used a volatile fuel mixture of T-Stoff and C-Stoff, which provided improved thrust and fuel efficiency over earlier models.
T-Stoff, or 'substance T', was a stabilised high-test peroxide used in Germany during World War II. It typically consisted of 80% hydrogen peroxide, with the remainder being water and trace amounts of stabilisers such as phosphoric acid, sodium phosphate, 8-oxyquinoline, and sodium stannate. In the Me 163, T-Stoff served as an oxidiser, combined with C-Stoff as the fuel in a bipropellant Walter HWK 109-509 engine. The ratio was approximately 3.1 parts T-Stoff to one part C-Stoff.
C-Stoff was a fuel mixture composed of hydrazine hydrate, methyl alcohol, and water. T-Stoff and C-Stoff are hypergolic propellants, meaning they spontaneously ignite when mixed at normal temperatures. This characteristic made it crucial to ensure that each propellant was correctly loaded into the designated tanks of the Me 163 during fuelling. The slightest contamination between the two substances could result in an explosion.
The use of this volatile fuel mixture in the Me 163's propulsion system contributed to its remarkable climb rate. However, the aircraft also suffered from compressibility problems that limited its safe diving speed to below Mach 0.82. Additionally, the Me 163's landing gear was problematic, often causing back injuries to pilots due to skids failing to extend or collapsing upon touchdown. Despite these issues, the Me 163's propulsion system represented a significant advancement in rocket technology during World War II.

The Me 163 was the first and only tailless rocket-powered interceptor
The Messerschmitt Me 163 Komet was the first and only tailless rocket-powered interceptor to see operational service. It was one of the Wunderwaffen (wonder weapons) produced by Nazi Germany during World War II. The concept for the Komet originated in the late 1930s when rocket propulsion for aircraft became attractive to air planners in Nazi Germany. The Me 163 was designed and produced by the German aircraft manufacturer Messerschmitt. The development of the aircraft can be traced back to 1937 and the work of German aeronautical engineer Alexander Lippisch and the Deutsche Forschungsanstalt für Segelflug (DFS).
Initially, the project was an experimental programme that drew upon traditional glider designs while integrating various new innovations such as the rocket engine. Lippisch and his team were transferred to Messerschmitt in January 1939, and plans for a propeller-powered intermediary aircraft were quickly dropped in favour of proceeding directly to rocket propulsion. The airframe was completed at the Messerschmitt works in Augsburg and shipped to Peenemünde West in early 1940 for installation of a Walter R I-203 engine.
The Me 163 had a remarkable climb rate, proving to be twice as fast as the British Hawker Tempest V, the highest-climb-rate prop-driven fighter that saw any combat during WWII. However, the aircraft had a short flight time, capable of a maximum of only seven and a half to eight minutes of powered flight. This was only about 25% of the 30-minute combat time that the Heinkel He 162A Spatz single-BMW 003 jet fighter possessed. The Me 163's high speed, coupled with the cannons' slow rate of fire and short range, made effective gunnery nearly impossible against slow-moving bombers. As a result, Me 163 pilots recorded a total of only nine to eighteen kills.
The Me 163's engine was fuelled by a mixture of T-Stoff (80% hydrogen peroxide and 20% water) and C-Stoff (hydrazine hydrate, methyl alcohol, and water). This fuel mixture provided a maximum thrust of 1,500 kg (3,300 lb). The Me 163's fuel efficiency was impressive, exceeding that of nuclear rockets. However, its high speed and short combat radius of 22 miles made it more of a conversation piece than an effective interceptor.

Its fuel was corrosive and hazardous to humans
The Messerschmitt Me 163 Komet was a rocket-powered interceptor aircraft developed by the German aircraft manufacturer Messerschmitt during World War II. It was the first piloted aircraft to exceed 1,000 kilometres per hour (620 mph) in level flight.
The Me 163's fuel system was troublesome, with leaks during hard landings that easily caused fires and explosions. The fuel and oxidizer were both toxic and required extreme care when loading into the aircraft. The hypergolic nature of the propellants meant that the Komets sometimes exploded on the tarmac. The high fuel consumption of the rocket propulsion system also posed significant design challenges.
Despite its advanced engineering and potential to revolutionize aerial combat, the Me 163 was more dangerous to its pilots than to its enemies due to the hazardous nature of its fuel. The corrosive and toxic fuel, combined with other design limitations, resulted in a high loss rate for Me 163 pilots during testing and training flights.

It was the first piloted aircraft to exceed 1,000 kilometres per hour (620 mph) in level flight, reaching a top speed of 1,004.5 km/h (624.2 mph) during a test flight on October 2, 1941. This speed record would not be officially surpassed until after the war.
The Me 163's remarkable speed can be attributed to its rocket propulsion system and aerodynamic design. The aircraft was powered by a Hellmuth Walter Kommanditgesellschaft HWK 109-509A-2 bi-propellant liquid-fuelled rocket motor, capable of producing a maximum thrust of 1,500 kg (3,300 lbf). This engine utilised a volatile fuel mixture of T-Stoff (80% hydrogen peroxide and 20% water) and C-Stoff (hydrazine hydrate, methyl alcohol, and water). The use of rocket propulsion offered significant performance advantages, but also posed challenges due to high fuel consumption and the corrosive and hazardous nature of the propellants.
The Me 163's airframe design was based on glider concepts, with a tailless configuration to balance the centre of gravity and centre of lift for stability. This wing sweep design, along with the powerful engine, contributed to the aircraft's high speed and climb rate. However, the Me 163's speed also presented challenges during combat. Its high speed coupled with the slow rate of fire and short range of its cannons made effective gunnery difficult against slow-moving bombers.
Despite its impressive speed and technological advancements, the Me 163 had limited success during the war due to various technical problems and fuel shortages. Its high fuel consumption and short flight duration of only eight minutes limited its effectiveness in combat. Additionally, the volatile and hazardous fuel mixture used in the Me 163's propulsion system posed significant risks to pilots and ground crew. As a result, the Me 163 saw limited deployment and had a high loss rate, with many aircraft lost during testing, training, and combat operations.
