MECO
Stage-Sep
Stage 2 Ignition
Boostback-Burn start-up
This time there is a stiffening ring on the MVac. It seems to me, on the launches where a ring is not present there is some kind of torus-shaped stiffener inside the engine's bell which stays on the first stage after separation. I don't thing this stiffener was present here.
I believe what you're describing as a stiffener inside the engine bell is the foam support ring for the MVac which has been there for essentially all Falcon 9 v1.2 missions, it is not related to the lack of the stiffener ring.

It's quite possible that you are right. But then I am totally baffled. Why sometimes there is the stiffener ring and sometimes there is not?

Congrats SpaceX Team & @SpaceForceDoD on completing 3 orbital Vandenberg launches in 11 days!
Might be a record.

I seem to recall in a Starlink launch thread that the stiffener ring was removed to reduce dry mass for additional payload capacity.

But why sometimes it's needed and sometimes it's not? If you can remove it to save weight (or time or whatever), why add it back?

My guess: customer preference.
It appears to be a recent Sx design tweak, and Sx may have decided that they don't need it for in-house payloads.
Customers may not be as adventurous, esp. for missions where the mass budget has so much margin that it allows for RTLS.

USSF apparently decided to use the lowest-use first stage available at Vandenberg.
Available first stages, with UTC date of most recent recovery:
1082.3 Feb 15 (Save for USSF-62 or WorldView Legion Flight 1?)
1061.20 Feb 23
1081.6 Mar 4 Starlink 8-1
1063.18 Mar 11
Edit April 5 UTC: It's B1081.6, skipping over B1082.3 and B1061.20.
Edit April 10: USSF-62 will launch on B1082.3.
Was this launch on the :00 second?

Seems that way to me.

Had a nice view from a hillside a few miles north, the marine layer held offshore but there was a lot of early morning heat shimmer in the air. Beautiful launch and landing regardless.

Wow! I was down south in the mountains above Santa Barbara and my view was occluded for the first minute. Can I get some approximate coordinates for next time?

Welcome to the Forum. Helodriver takes those from the VSFB. I have a Google map with the approximate sightline that he took based on building references (satellite dish and the large brown building). There is a thread that you can read up on for views
