Why do you think Kuiper is dead in the water?
So far they launched 2 test satellites. They contracted most of the launches to either new rockets or ones in development, like New Glenn, Ariane 6, ULA Vulcan. They actually had to contract three Falcon 9 launches to help out with that. In reality, I think SpaceX will end up launching a lot more than that.
Unless FCC is willing to be lenient, 50% of the satellites will be hard to accomplish by the deadline.
I am sure it's doable if all the space providers work together and there aren't any showstoppers.
Are you living in a different world that me?
NO company or Government on Earth outside SpaceX has the capability to launch more than about 15 orbital rockets per year. Most are in the 5-10 per year range.
Who the heck is going to launch all these sats?
> NO company or Government on Earth
Not that it's a possibility for Kuiper, but China had 67 launches in 2023.
