Orion 50XL
Orion 50XL is the exact vectorable solid rocket motor variant used as Pegasus XL's second stage and Minotaur I's third stage. Northrop Grumman's launch-vehicle guides preserve both installations, while its current propulsion catalog identifies Orion 50 XL as a 50.2-inch-diameter, 120.9-inch-long, flight-proven vectorable motor. The existing typed performance block remains the row's normalized mission-specific values; no broader production claim is made here. Exact vehicle configurations and stage context remain on the vehicle-family records.
