Not really sure if this belongs here or not but does anyone know how many Castor 120 stages are left, and if there aren't any, what sort of performance increase to Minotaur-C the Castor 120XL brings?
It was nice to see this fly successfully.
From 2016 OA Motor Catalog Data:
Note: Castor-120XL is the civilian version based on the newly developed LCS I (Large Class Stage I) for military and government applications.
