The A-4 from 1954? F-117 from 1981? B-21 that's been in development since 2015 and has had only 3 delivered so far? These are 10 year development program, the Starship still has some years to go and I'd argue a reusable moon rocket is a bit more involved than a bomber plane.

War fighting technology like aircraft is a different thing than orbital rockets and spacecraft. I'm not trying to downplay those achievements, especially the F-117, but it's apples to oranges.
