Telstar 19V is, I believe, the most massive payload to reach geotransfer orbit. It is an SSL-1300 model built by SSL/MAXAR (Palo Alto)

We'll see when the TLEs come out
The speed shown at SECO-2 was around 32400 km/h or ~9.0 km/s so the orbit should be a bit sub-synchronous.

Quite a bit - I estimate that would be 13000 km apogee or so. Subsync makes sense, with part of the enormous payload mass being extra prop for orbit raising. But we'll see soon enough

Is the apogee around 13000 km or 18000 km? Since I saw that someone posted here showing a 17863 km apogee: https://www.reddit.com/r/spacex/wiki/launches/gto_performance … Which one correct? Thanks.
