Vacuum Thrust (lbf)
ORION 32
VECTORABLE NOZZLE IN-LINE BOOSTER
The Orion 32 is a low-cost, high-performance derivative of an
existing upper-stage motor. This development motor is 121 inches
long and nominally designed as a second-stage motor. A longer
version (up to 255 inches) for potential first stage application and a
reduced length version (down to 70 inches) are also in design
evaluation. This motor configuration has not flown; however, all
components, except skirts, are flight-proven.
