Originally contracted to fly on Ariane 6:

Already discussed in the Ariane 6 thread, Galaxy 37 aka Galaxy 13R. SpaceX has the launch order for this satellite.
I don't know when the switch from Ariane 6 to Falcon 9 took place.

There is already launch provider 1 (SpaceX) for the Galaxy 13R planned.

What I have read out. Galaxy 37 also has a Ku-band payload.
It should possibly be marketed as Horizons 4. Similar to Horizons 1.
However, I do not know whether Intelsat already agrees with SKY Perfect JSAT on this.
C-band is divided into 2 footprints. The upper 200 Mhz are intended for CONUS.
The lower 300 Mhz e.g. for Alaska and other zones not affected by the C-band clearing.
Launch mass guess, maybe similar to JCSAT-14.

Cross-post; slight firming-up of in service date (Q2 2023 vs Q2/3 2023) > same for launch date?

Q2 status report [June 30]

Intelsat said SpaceX will launch its final C-band replacement spacecraft in the second quarter of 2023.

I assume Intelsat 37 is Galaxy 37

SpaceX is slated to launch Intelsat-37, the final satellite left to launch in this spectrum-clearing strategy, on a dedicated Falcon 9 in June.
