Wonder if Bruno is having second thoughts about picking Blue Origin over AJR.
I wonder why ULA ever thought intentionally putting yourself at the mercy of a competitor (and an unproven one at that) was a good idea.

Why bother?
This could be advantage for Musk and SpaceX

1. First ULA would depends on SpaceX on Engines, not would-be competitor Blue Origin.
2. Next to that would Space Force be grateful for support and show appreciation in form of new contracts.
3. Also "Elon Musk comes to Rescue" could help in Capitol Hill against current Bezos lobbyism.

it's win win win situation for SpaceX...

Debut launch of @ulalaunch Vulcan slipping to 2022 as customer @astrobotic needs more time to prep Peregrine lunar lander. "Covid presented a lot of problems for the entire space supply chain," CEO John Thornton tells @aviationweek "We're just doing the best we can."

Vulcan prev slated for late '21 launch, with @blueorigin BE-4 engines, now in pre-qual testing, the pacing item. "We like the performance—it’s better than I expected," says @torybruno " We’re still going to drive toward having that rocket ready. In our business ...

you always want the rocket waiting on the spacecraft and not the other way around.”

Video from getting ready to test #Vulcan ‘s thrust structure at @Dynetics. This light weight, finely tuned, and perfectly designed set of rings And trusses conveys 3.5 million pounds of thrust into the rest of the rocket’s structure. #ToryTimelapse

Will the engines stick out of the holes in the orange structure entirely, just the nozzles or will the nozzle edges be level with the holes?

Tory Bruno with probably his sharpest public words yet on Blue Origin the BE-4 engine delay. Privately he's quite a bit sharper, hah.

"I need them to diligently work through the plans we have and get done on time."

Blue Origin will not deliver the BE-4 engines for the inaugural launch of ULA's Vulcan rocket "before the end of the year," CEO @torybruno tells @GregAveryDenBiz, emphasizing that he needs Bezos' company "to diligently work through the plans we have."

Bruno added that ULA has "been able to accommodate" the delay, "but I’ll be straight with you, the dates we’ve set up for them now— we really don’t have the ability to make any big moves after this."

Bruno: "“We really like the engines ... The engines are performing well, and the design has stabilized, and it’s now really a matter of getting through the test program and fabricating the flight engines … It’s the endgame now.”

I expect engines before the end of the year. If there are any unforeseen challenges, they could move past that. At present, the engine is performing well and is in prequal testing. Flight engines have begun fabrication. I expect the have the rocket ready ahead of the payload

Sounds very positive. What is involved with prequal testing?

In general,Prequal is like path funding for qual and usually involves some additional testing that gives some indication of margins

Why didn't @ulalaunch develop their own rocket engine?

The #VulcanCentaur PTT booster was transferred from the SPOC to the pad today for a series of fueling tests in the coming weeks #CountdownToVulcan

Vulcan should have been Pyrios with J-2 upper stage…go for low part count.
