@aguado_mate@Truthful_ast@EddGorenstein The RL10s don’t get Shuttle all the way to orbit, though. It uses the OMS to circularize, which is a completely separate propulsion system that even burns a different fuel type. If Buran counts as a stage and not just a spacecraft, so does shuttle…
@Truthful_ast@ScottLikedSLS Yeah, and the Su-57 is 5th-gen if you go by the Russian definition of fighters… Oh and ICBMs count as hypersonic as well… Russia’s definitions are kinda stupid.
@Erdayastronaut I mean, in a couple of weeks we should be getting the first Starship Starlink mission. At this point, the V2(mini) constellation is complete, so there’s less of a need for Falcon to replace them. V3 can only fly on Starship.
