Orion 50SXL
Orion 50SXL is the exact fixed-nozzle solid rocket motor variant used as Pegasus XL's first-stage motor. Northrop Grumman's Pegasus XL guide preserves the first-stage installation, and its current propulsion catalog identifies Orion 50S XL as a 50.2-inch-diameter, 404.3-inch-long, flight-proven fixed-nozzle motor. The existing typed performance block remains the row's normalized values; exact Pegasus XL stage and placement context remain on the vehicle-family records.
