Propulsion

Two stages, each incorporating a regeneratively cooled, turbo-pump driven liquid
rocket engine operating on a gas generator thermodynamic cycle. Burning a
mixture of liquid oxygen and refined Kerosene, the first stage booster engine is
designed to produce 86 tons of thrust at sea level and incorporates hydraulic thrust
vector control for pitch, yaw and roll control. The second stage, sustainer engine is
designed to 5.8 tons of vaccum thrust and is similarly steerable via electromechanical
actuators.

Avionics

Dual redundant flight control computers, receiving navigation data from dual
redundant strap-down inertial navigations systems provide vehicle ascent control.
Real time telemetry data, flight termination and ground tracking systems provide for
reliability and safety of the system during ascent.
