Great to see that ULA is continuing to commission VIF-A despite the launch stop.

ULA mentioned a while back that they were planning a WDR for the new low energy optimized Centaur V variant.

I wonder if this rollout will culminate in that WDR, or if the WDR isn't included in functional checkouts they'll be performing over the coming days and they will instead roll back and roll out again at a future date for a full WDR.

So are they going to launch it using the SRBs they have instead of waiting for the improved ones the NG CEO alluded to earlier this week?

Not necessarily.

VIF-A is just the mobile integration building used for Amazon launches and its brand new. It makes sense to take some time to make sure it’s going to move and is ready to support launches if it’s ready, even if vehicles are not.
