Wow, this is I believe the very 1st firmed Starship GEO communication satellite launch contract!?
QuoteWow, this is I believe the very 1st firmed Starship GEO communication satellite launch contract!?I would say that Turksat 6A2 was earlier and firmish (with option on other LV).
Someone from SpaceX has been quoted some time ago that SpaceX launch contracts usually include the option to launch on Starship. I think Turksat 6A2 was the same case, so not a real confirmation or announcement.
Superbird-9 will be launched by SpaceX’s Starship launch vehicle in 2024

Why not mention what the prime contracted vehicle is?

Why not mention what the prime contracted vehicle is?I didn't say Starship was just an option in Superbird-9's case.That's why I think it's the first real commercial contract announced for Starship.

But more interestingly, this is a GTO launch. Wouldn't that require on-orbit refueling?
Why Starship and not FH?Contract with Airbus to build Superbird-9 was announced in March 2021. Seems unlikely to me that they were planning a satellite beyond FH’s capabilities? Also the FH manifest already goes beyond 2024.So SpaceX perhaps offered a good deal on Starship to get the ball rolling?

Wouldn't that require on-orbit refueling?Per the already outdated 2020 Starship's PUG, it should be capable of launching over 20 tonnes to GTO without refueling. It's when you go beyond that when you do need refueling.

If the Starship was launching to GTO, the end result will be that the Starship itself will be on the same GTO orbit. In which case, a very small burn at apogee should be enough to ensure reentry at the next perigee. Or at least a dip into the upper atmosphere for aerobraking with reentry coming on the next orbit.

They all could be lifted by a Falcon 9 in RTLS mode.
I wouldn't assume a payload has to be large/heavy just because it's going on Starship.
Presuming an estimated launch cost of $160M to GTO by the Starship split between 4 or 5 large GEO comsats. That will be a cheap launch opportunity too tempting for a comsat operator to pass up on.If my guess is correct. It is terrible news for SpaceX's competitors.
