SpaceX has leased SLC 6 at VSFB for it's Falcon 9 program. They have 2 launch pads at SLC 4 for the Falcons already. SLC 6 was modified for the Space Shuttle in the 80s. With all the Shuttles being parked they remodeled it for the Saturn Vs. Launched the last of those last fall. Now SLC 6 is Elon's new beach front property. From the report I read about the damage that Starship launch did on their launch pad in Texas, they're gonna need a complex like SLC 6.
