I guess Vulcan’s not the only rocket that had GSE problems.

FH has a ways to go to match the "Pad Princess" reputation of Delta IV Heavy. We'll see about Vulcan, but I can't imagine it ever getting that "bad", either.

Now targeting no earlier than Wednesday, December 13 for Falcon Heavy to launch USSF-52. The extra time allows teams to complete system checkouts ahead of liftoff. Teams are also keeping an eye on weather, which is 40% favorable for launch → spacex.com/launches

That means that the other one gets bumped, too.

Not so far. The two launches are unrelated and it appears to be the weather that moved Starlink yesterday. It's more favorable tonight than last night.

SpaceX is currently standing down from a Falcon Heavy launch of USSF-52 to orbit to perform additional system checkouts. The payload remains healthy while teams work toward the next best launch opportunity. We’re also keeping an eye on the weather and will announce a new launch date once confirmed with the Range.

Given that Doug is returning to Port Canaveral, I'd say the next launch attempt is at least ~1 week away as for the first attempt Doug departed ~4 days before launch:

Quote

SpaceX recovery ship Doug is returning to Port Canaveral following the delay to the Falcon Heavy USSF-52 mission. The ship was due to recover the fairing.

The ship retuning indicates a long-term delay.

USSF-52 might slip more, as SpaceX has started the process of bringing Falcon Heavy into a horizontal position.

Now the question is if they can perform the needed work on the pad, or if we will see a rollback to the hangar.

SpaceX personnel at LC-39A prepare Falcon Heavy for rollback into the HIF - additional work is needed before launch.

Does this mean that the problem was vehicle/spacecraft related?

Or just that after a delay the spacecraft needs additional servicing?

With DOD flights I just always assume it's the payload.

Seen too many that are on the pad ready to go then something comes up and it's month till it's back on the pad.
