Junkers RT-8 (Saenger I) Rail Launched Space Plane

Junkers RT-8 (Saenger I) RT-8 Sled Launch: Launch System: Sled-launched two-stage space plane Sled Propulsion: Steam rocket Launch Distance: 3 kilometers Stage Separation: At 30km altitude First Stage: Power: Three airbreathing LH2 engines Power Output: 150 tons at sea level Stage Length: 80 meters Wing Span: 40 meters (shoulder-mounted delta wing) Stage Separation and Second Stage: Separation Altitude: 30km Second Stage Propulsion: Single Lox/LH2 engine Second Stage Options: Manned: Capable of carrying two astronauts (HORUS - Hypersonic Orbital Upper Stage) Cargo: Unmanned cargo ship (CARGUS) without wings for a return trip Second Stage (HORUS/CARGUS): Length: 31 meters Wing Span (Orbiter): 12 meters (low-mounted delta wing) This craft was an ambitious early space shuttle design with innovative sled-launch technology, multiple stages for different purposes (manned, unmanned, cargo), and hybrid propulsion systems. The two-stage design allowed for versatility in missions, either for reaching orbit or suborbital flights, demonstrating the adaptability of its components for various space missions.
