Z11000 Specs

Table 1. First Stage Specifications
Name Spec Value Notes
Cores 2 Three cores make up the first stage. The side cores are connected at the base and at the top of the center core’s liquid oxygen tank. The two cores generate 11,637 kilonewtons of thrust at liftoff.
Engines 19 Shortly after liftoff 11 of the engines are throttled down. After the side cores separate, the 11 engines throttle back up to full thrust.
Mini Engines 22 Inside each core is a cluster of 22 mini engines. These same engines power the X22000, enabling efficiencies that make the Z11000 the most cost-effective light launch vehicle in the world. With a total of 19 first-stage engines, the Z11000 has engine-out capability that under most payload scenarios can sustain up to three unplanned engine shutdown at any point in flight and still successfully complete its mission.
Thrust at sea level 17034 kN The engineers achieved this through the use of a special API called z11000_thrustAtSeaLevel_2Core_19Engine_22MiniEngines_Version43562232.32455-3322a
Thrust in vacuum 19482 kN
Height 53.7 m Measured from lowest to highest point
Width 9.78 m Measured from widest point
