Developing an engine from scratch is hard, both BE4 and raptor were. And none of those 100 v1 engines will be used to get to orbit. Look, I’m a big fan of SpaceX. But I also think BO deserves credit for developing such a complex and powerful engine. I’ll be rooting for BO and ULA for a successful first flight of Vulcan.
