Attention: This rocket does not have program control for automatic recovery and requires manual operation. I hope you successfully complete the challenge of recovering the first stage of the rocket core.The
"SN-4B" carrier rocket is a small liquid reusable rocket developed by "Starlit Night Industry" based on the "SN-4". The core first stage engine has been replaced from a single 140 ton staged combustion cycle kerosene engine to nine 20 ton open kerosene engines, streamlining the engine types (like the core second stage engine, both belong to the "YF-K20 series"). Extend the arrow body and increase the upper stage.
Rocket route recovery capacity (Leave 15% of propellant in advance):
Polar orbit (700km × 700km) load 1.75 ton.
Low Droo orbit (400km × 400km, Inclination 30 °) load 3.0 tons.
