Walter rocket engine

Target entity: Walter rocket engine
Context triple: [T-Stoff, propulsionSystem, Walter rocket engine]

• A. Curtiss-Wright XLR25 rocket engine
  The Curtiss-Wright XLR25 was an American liquid-fueled rocket engine developed in the 1950s to power high-speed experimental research aircraft such as the Bell X-2.
• B. Raptor engine
  The Raptor engine is SpaceX’s next-generation full-flow staged combustion methane-fueled rocket engine designed to power the Starship launch system.
• C. CE-20 cryogenic engine
  The CE-20 cryogenic engine is an Indian-developed, liquid hydrogen–liquid oxygen rocket engine that powers the upper stage of ISRO’s heaviest launch vehicles for placing large payloads into orbit.
• D. RS-68 engine
  The RS-68 engine is a powerful liquid-fueled rocket engine used primarily on the Delta IV launch vehicle, known for its high thrust and simplified design for cost-effective heavy-lift missions.
• E. Rocketdyne H-1
  The Rocketdyne H-1 was a kerosene/liquid-oxygen rocket engine developed in the United States and used on early Saturn launch vehicles during the Apollo era.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Walter rocket engine
Target entity description: The Walter rocket engine was a German World War II-era liquid-fuel rocket propulsion system, best known for powering the Messerschmitt Me 163 Komet interceptor and pioneering high-thrust, short-duration flight technology.
