i wonder what gone happen
if Elon Musk provide ULA with Raptor engines for Vulcan ?

This could be advantage for Musk and SpaceX
Cost was, as I understand it, a large reason.
Not so cheap now.Cost was, as I understand it, a large reason.
Vulcan’s aft structure and heat shield (upside down) took a beating to ensure reliability. Recent successful SRM separation shock testing with our strategic partner @Dynetics. #VulcanCentaur #CountdownToVulcan
GAO: A U.S. produced rocket engine under development for ULA’s Vulcan launch vehicle is experiencing technical challenges
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?
@torybruno Was BE-4 the first choice for Vulcan , or was Vulcan specifically tailored to have BE-4s?
We surveyed and traded every engine flying or on the drawing board
It's here! Grab the official Peregrine Mission 1 patch to commemorate this historic mission, launching in 2022 with 18 commercial payloads and 6 different countries aboard! astrobotic.myshopify.com
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?
View: https://twitter.com/sights83893134/status/1430237604478214148Actually, what I said was that the availability of the payload will place the first flight, and the availability of the engines will pace the rocket (ahead of that)
Is all the Vulcan hardware built for the first flight @torybruno?
@torybruno Do you see Vulcan needing two launch pads in the future to avoid scheduling issues?
I spy with my little eye… An advanced Centaur V tank nearing completion in our new robotic weld center at the rocket factory in Decatur, AL. #CountdownToVulcan
The #VulcanCentaur PTT booster was transferred from the SPOC to the pad today for a series of fueling tests in the coming weeks #CountdownToVulcan
Today at Space Launch Complex-41, the #VulcanCentaur pathfinder was filled with liquid oxygen for the first time -- an important milestone in the #CountdowntoVulcan! bit.ly/countdown-to-v…
Ice is coming… #VulcanCentaur got a bit frosty earlier this week when LOX flowed through the rocket for the first time! #CountdownToVulcan #ToryTimelapse
View: https://twitter.com/kordi197/status/1435559219093282821Ask, and you shall receive… First complete Centaur V tank in the Rocket Factory. (complete with the fixturing that supports its ultra thin skin when unpressurized). It’s a beast… #vulcancentaur
How ultra thin are we talking?
Are you still confident the BE-4's are on target for launch?
A little #VulcanCentaur to go with your Monday morning coffee. Payload fairing (PLF) separation system testing @NASA_Marshall. The 5.4m PLF separates using a debris-free horizontal & vertical separation system with spring packs and frangible joint assembly. #CountdownToVulcan
Over @NASA_Marshall #VulcanCentaur is undergoing payload accommodation structural qualification testing. For Vulcan, the payload will be encapsulated in a bisector PLF, which attaches to the top of Centaur V #CountdownToVulcan

The Pathfinder Tanking Test operations continued this week as the #VulcanCentaur rocket was successfully fueled with liquified natural gas (LNG) propellant for the first time! #CountdownToVulcan https://www.ulalaunch.com/rockets/vulcan-centaur/countdown-to-vulcan
Man, I got a lot of grief for this comment last year. Who knew I was being over-optimistic?
Yes, but it's at least 12-18 months away from first flight.
What’s your current estimation now?
second half of 2022. hopefully.
I'm not. It's going to take 6 months, at least, from BE-4 delivery. Then tests need to go well. Then the payload needs to be ready. I think second half of 2022 can very much happen but I wouldn't guarantee it.
Rocket-Rocket... Vulcan in the SPOC and Lucy's Atlas on the pad during its Wet Dress Rehearsal.
