>>12954458ULA has the problem of not being very independent. Lockheed and (especially) Boeing aren't very interested in intensive funding of esoteric or really ambitious innovations (especially when those would threaten their existing business lines). ULA's cost structure seems to be high and rigid, such that their revenue from US government contracts doesn't create the surplus needed to push to completion development of internal projects that others aren't directly contracting them to build. So they have these grand plans that they're really in love with (like ACES), but then they're forced into at best incremental approaches. With Artemis picking up, the opportunity for these high-performance, long-duration, maybe even r*usable projects is greater than its ever been, especially if Artemis produces a decent ISRU infrastructure.
