Half a decade ago, ULA bragged that they were able to launch with a six-day gap between launches, also on opposite coasts. They haven’t repeated that accomplishment since. SpaceX has since made multiple launches in a week almost routine. A few weeks ago, SpaceX launched three Falcon 9s during one weekend. Now they are able to do two before the sun sets. SpaceX has done much to advance the state of the art.

Reusability, rather than manufacturing capability, has made such a high cadence practicable, and the low cost of launch has made it practical.

Block 5 Falcon 9 is now a perfect 123 success in 123 launches. I cannot think of another launcher which has reached this number of launches without even a partial failure. Let alone *landed* most of their stages.
