This is Recovery; the center core has landed. All landing operators, proceed to Procedure 11.000 on ECRY and ECF9 Net.

Good separation!

WGS 10 separation has occurred.

The 5,987-kilogram satellite is ready to help augment the U.S. Air Force's capability of supporting our joint warfighters.

Congrats to ULA and the U.S. Air Force. Looking forward to sending off the Delta IV Medium this July.

Webcast is coming to a close by showing a replay of the 00:26 UTC launch from Cape Canaveral.

Have a good night, everyone.

Thank you, Chris, Steven, and Zach for the launch coverage!
Congratulations to the entire launch campaign team!

One more Delta Medium launch before the single-stick's retirement.

It looks like the actual liftoff time was 00:26:00.18 UTC.

00:26:00.1 A
A - actual (first motion)
P - planned (first motion)

This statement is wrong. There's several more Delta IVs that have launch assignments. What this was the penultimate of was the Medium+ version AKA single-stick version. The rest are Delta IV Heavies for the NRO.

Was touch and go for a while if we were going to get off the pad but all the teams worked through all the issues including TDRSS. Congrats and well done ULA/USAF keeping cool though all and kudos to team NSF for staying on top of it! :)

True, I interpreted it as only one more of these launches with RS-68A and solids firing together, but I guess if he was talking about the solids he should be referring also to "motors"... in any case, only one DIV-M+ left.

Not wrong.  Chris Boex said "Those engines..."  Plural.  There is only on RS68, so "those engines" must refer to the SRBs.  There is only one more Medium launch, the Heavies don't use SRBs, so the statement, while vague, is correct.
