They're working on commercial products, too, like New Glenn and Blue Ring. They're also supposedly working on a reusable upper stage and a crew capsule. They've been developing at a pace more like ULA (Vulcan) or Boeing (Starliner) instead of Rocket Lab or SpaceX. The SpaceX approach with Dragon has been pretty well praised. Their development phase with Falcon landings and now Starship test flights harkens back to the early days of spaceflight instead of the slow and steady and not necessarily safer process that has become too common.
