I don't think one should blame them for not picking a good option when there weren't any good options available.

At an absolute minimum, they should have contracted for a whole lot more than three F9s in December 2023

The Starship delays presumably mean there are more Starlink Falcon launches than anticipated and that may naturally have produced a short-term Falcon supply shortage. SpaceX could probably increase Falcon capacity but this would take time and they may be reluctant to make this investment given the fact that they want to discontinue Falcon. SpaceX could bump Starlink to launch Kuiper but they may be reluctant to do so in order to launch a Starlink competitor (among other things the Starlink team would naturally feel they were being treated unfairly if that happened). I'm not saying that SpaceX definitely didn't give Amazon a good offer, just that we don't know if they did and shouldn't assume they did.In any event SpaceX appears to have a monopoly on launch suitable for large constellations in the very short term and I think the FAA should avoid forcing anyone to buy from any (temporary or permanent) monopoly since monopolies are not in the public interest.
Bruno said once Vulcan starts flying Kuiper missions, it will launch 45 satellites with each flight. Atlas 5 rockets will carry 27 satellites each. Bruno said for these mega-satellite constellations, it’s important to get as many satellites on orbit as quickly as possible.

Now we can better calculate what launch rate is needed to meet the FCC deployment deadlines.

Since the October test sat launch we’ve seen Kuiper production move from late 2023 to H2 2024. It seems unlikely that we will see Kuipers flying on Atlas before Q3 and more likely Q4. So, apart from possibly a few Atlas flights late on 2024 is shaping up to be a bit of a washout for Kuiper.Things don’t look to be much better for 2025. With Tory confirming that the Q4 Dreamchaser flight will be Cert 2 and USSF-106 now scraping in at the end of 2024 (possibly 2025, Wow!) pushing two or three more flights into the enormous bow wave of DoD launches. Add to this mix the Atlas V Kuiper flights that won’t now be flown in 2024 and it seems unlikely that many Vulcan Kuiper missions will fly in 25 and indeed H1 26.I don’t hold out much hope for Ariane 6 which is also progressing slowly and facing a backlog of government missions.So it’s all up to Falcon and New Glenn now. More delays seem inevitable. My sweepstake call is only 800 Kuiper Sats operational by July 2026.
They also reserved eight Atlas V LVs, which are presumably ready to go as needed starting now. The fact that they are not using them points to issues with the satellites or satellite production rather than launcher availability. Did they discover a problem with the 2-satellite test flight? That's why you do test flights, after all. Eight Atlas V plus the 3 Falcon 9 are still nowhere near enough to launch 1616 satellites by July 2026. I don't know how far in advance you must reserve Falcon 9s, but maybe it's time to do that. SpaceX accommodated OneWeb in less than 9 months, but that was for their first of only 3 launches, and was a response to the unanticipated sudden loss of Soyuz launches. SpaceX has no such reason to be extra-accommodating for Kuiper, whose problems appear to be self-inflicted.

That in turn means they must plan to get a waiver from the FCC. But I suspect that just about everybody in the industry, not just SpaceX, will oppose that.

But I suspect that just about everybody in the industry, not just SpaceX, will oppose that.How many Kuiper satellites would represent a Minimum Viable Product?That might be enough so that at least one satellite is visible from any place in the USA (Hawaii & Alaska excepted). If they haven't even got to that by the July 2026 deadline, ISTM it would make their application to the FCC for an extension even more problematical
