Super SARV Retro is a longer, higher impulse version of the STAR 12, used as a retrograde rocket for an unmanned satellite vehicle. For all future deliveries, changes will be made to this design. Due to the unavailability of outdated materials, the main grain propellant will be changed from TP-G-3085 to TP-H-3340. Because of the higher flame temperature of the TP-H-3340 propellant, the molybdenum throat insert will be changed to G-90 graphite material. Total impulse 6,232 kgf-s. Propellant mass fraction 0.67.
