The New Shepherd uses the BE-3. The BE-4 the Vulcan will use has never flown. ULA has never built a new launch system. Based on their track record early next year is optimistic. ULA has no real plans for re-use, they’ve never even funded a test program for the SMART plan, and Blue Origin has never demonstrated propulsive landing capabilities for an orbital class booster. |
