United Launch Alliance entered an vital new period for the corporate with the debut of its Vulcan rocket in early January. The flight was one which was extremely anticipated by these each inside and out of doors ULA and, by all metrics, it was a extremely profitable mission for ULA.
To mark a month after this inaugural launch, Spaceflight Now sat down with ULA President and CEO Tory Bruno for a dialogue about that first certification flight and the yr forward for the corporate and the rocket.
“This was the cleanest first flight I’ve ever seen. I’ve personally been concerned with about three dozen of them,” Bruno mentioned. Previous to his time with ULA, Bruno was the vp and normal supervisor of Lockheed Martin’s Strategic and Missile Protection Programs.
Bruno was among the many launch staff on console throughout the countdown, which was run from the Superior Spaceflight Operations Heart (ASOC) at Cape Canaveral Area Power Station. He mentioned the dearth of points throughout the countdown threw him for a loop at occasions.
“It was a really clear countdown. Not an exaggeration, true story, there’s most likely 25 minutes or so, I’m sitting on console, silence and I assumed my headset was busted,” Bruno mentioned. “I’m like, ‘Maddie, discover IT, my headset is damaged.’ They arrive again, ‘No, Tory, there’s actually nothing taking place. It’s simply that quiet.’”
Bruno mentioned the one problem got here in the direction of the top of the roughly 320-second first stage burn of the Vulcan booster: it ended about 1.2 seconds early. He described that as a thermal modeling problem the place the final little bit of propellant that was transferring by the feed line was hotter than anticipated, which triggered the shutdown.
“That was lower than a sigma, like 7/10 of a sigma in efficiency, which might be nicely inside flight-to-flight variation. So, that may be a post-flight statement,” Bruno defined. “Clearly, we knew it did that in actual time. Afterwords is after we understood it was a thermal modeling problem.”
Bruno mentioned the seemingly resolution will likely be to regulate the quantity of propellant reserve to account for that. He mentioned that work will likely be performed in time, however that it isn’t a urgent problem for his or her subsequent a number of flights.
He mentioned whereas that was the one problem of observe, they’ll proceed reviewing the info by the top of February. The explanation for that’s as a result of with information handoffs that occur between floor stations throughout flight, there are items of the puzzle that must be fitted collectively in a radical, post-flight evaluation.
“Over time, all this different information is available in, it will get cleaned up, it will get synchronized in time and occasions as a result of clearly information you acquire in Guam versus actual time information down from TDRSS (Monitoring and Knowledge Relay Satellite tv for pc System) just isn’t going to be precisely in the identical time reference. So you must do all of that manually and then you definately comb by it,” Bruno defined.
“So, that’s why it’ll take till then. They haven’t discovered something but. It’s simply actually the cleanest first flight I’ve ever skilled. It was just like the ninetieth Atlas, not the primary Vulcan.”
Dream Chaser and Cert-2
With the primary flight of Vulcan now largely within the rearview mirror, the ULA staff is urgent forward with the second certification mission. The payload is Sierra Area’s Dream Chaser spaceplane on a cargo provide mission to the Worldwide Area Station.
Bruno mentioned they don’t want to attend for the conclusion of the info evaluation to proceed the momentum on this subsequent mission.
“We’ll simply proceed to construct and ship and transport and be prepared. We’ll do this in parallel as a result of it’ll end up fairly quickly,” Bruno mentioned. “We’re most likely 20, 25 days away from fully ending each final little bit of knowledge evaluation. So, no purpose to attend for that. We’ll work in parallel.”
When Bruno spoke with Spaceflight Now on Jan. 31, he mentioned that each the Vulcan booster and the Centaur 5 upper-stage had been constructed and that the Blue Origin-built BE-4 engines that energy the primary stage had been out in Texas for testing.
“As soon as they arrive by, then we are able to end it and we’ll be able to go,” Bruno mentioned. “After which we’ll be ready on our payload, which is the way in which we prefer it.”
On Feb. 5, Bruno posted to social media, stating that one of many BE-4 engines for the Cert-2 mission contained in the rocket manufacturing facility in Decatur, Alabama. A pair days later he shared a picture of the engine as nicely.

Reaffirming what he beforehand said earlier than the Cert-1 launch, Bruno mentioned that so far as Vulcan readiness is worried, ULA can be ready to help the Cert-2 launch within the April timeframe. He mentioned as a result of they’ve two staging areas for rocket integration, that gained’t create a battle with the Crewed Check Flight of Boeing’s Starliner spacecraft, which is concentrating on a launch no sooner than mid-April.
In the meantime, up in Sandusky, Ohio, at NASA’s Glenn Analysis Heart, the Dream Chaser spaceplane, dubbed Tenacity, is present process environmental testing earlier than it is going to be shipped all the way down to the Cape to undergo closing checkouts and cargo loading.
Talking at a media occasion earlier than the subsequent stage of testing started, Sierra Area CEO Tom Vice described their pleasure at lastly reaching this stage.
“We’re popping out of years of improvement, years of arduous work, years of resolving actually robust engineering challenges that come from revolutionizing the way in which we do issues,” Vice mentioned. “And we’re actually excited that this yr we enter orbital operations for NASA. It’s a yr that we alter how we join Earth and house.”
Nationwide safety readiness and West Coast launches
Getting by these two consecutive certification flights are crucial for ULA in clearing the car to start out flying Nationwide Safety Area Launch (NSSL) missions.
“[Assured Access to Space] has a brand new entrant cert. information that defines these other ways. And once you look by that, you may truly see there’s a wide range of methods a launch service supplier can certify,” mentioned U.S. Area Power Lt. Col. David Schill, the Area Launch Delta 45 Vulcan Centaur materiel chief, in a pre-produced video concerning the Vulcan Cert-1 launch.
“What ULA has performed is they chose an strategy, which requires two consecutive, profitable launches. And along with these two consecutive, profitable launches, a authorities staff has technical perception into and acceptance of the system design,” Schill mentioned. “So, that’s actually distinctive on this case and which makes Vulcan particular is that deep, technical perception that we have now into this system.”
By way of 5 years of NSSL Section 2 Contract Launch Service Process Order awards, ULA has 48 missions forward of it which can be valued at about $3.1 billion. Amongst these missions, 47 will likely be launched utilizing its Vulcan rocket.
The primary such mission on deck for Vulcan will likely be USSF-106, a multi-manifest mission consisting of the Navigation Know-how Satellite tv for pc-3 (NTS-3) and one other payload for the U.S. Area Power.
These missions are coordinated by the U.S. Area System Command, which is headquartered on the Los Angeles Air Power Base in California. Whereas SSC mentioned the precise value of the U.S.-106 mission with Vulcan is proprietary info to ULA, it has publicly said that the mission was a part of a two-launch award price $278.7 million. The opposite mission in that bundle, USSF-51, is ready to launch utilizing ULA’s Atlas 5 rocket as quickly as March.
In a joint assertion to Spaceflight Now, Col. Doug Pentecost, the SSC’s Deputy Program Government Officer for Assured Entry to Area, and Michael Sanjume, the senior materiel chief for Vulcan Programs and Operations described the timeline following the Cert-2 launch.
“As soon as ULA has accomplished their second certification flight (‘Cert-2’), the federal government will do its closing evaluation for certification over just a few months, permitting for USSF-106 to launch this summer season,” they mentioned of their assertion.
Between ULA’s three rockets, Pentecost and Sanjume mentioned there are 5 NSSL missions on the 2024 manifest:
- USSF-106 – Vulcan
- GPS 3-SV07 – Vulcan
- USSF-87 – Vulcan
- USSF-51 – Atlas 5
- NROL-70 – Delta 4 Heavy
USSF-51 and NROL-70 are slated to be the ultimate NSSL missions utilizing ULA’s legacy rockets, in keeping with Pentecost and Sanjume. The latter of the 2 will mark the ultimate Delta rocket to launch earlier than that line is formally retired.
Bruno mentioned there are vital causes to retire the Delta 4 Heavy, not least of which is the fee financial savings per launch with Vulcan. However he mentioned it is going to be considerably unhappy to see it’s closing flight.
“It’s a ravishing rocket. It’s launched superb missions. It’s probably the most metallic of all rockets, as I prefer to say. It units itself on fireplace earlier than going to house,” Bruno mentioned. “I simply like it and so, we’re all going to overlook it. It’ll be bittersweet.”
The ultimate award of NSSL Section 2 missions final yr got here as ULA and different launch suppliers are jockeying for the Section 3 missions. These will likely be break up up into two lanes: Lane 1, which opens up alternatives for newer launch corporations and smaller rockets and Lane 2, which requires a functionality to launch payloads to any and all orbits.
That second lane could have a 60-40 process order break up with a carveout for seven missions for a complete of as much as three suppliers. Bruno mentioned ULA will compete to win the 60 % slice of the pie as they did with Section 2, however mentioned the 40 % slice is ok as nicely.
“They’re all attention-grabbing missions. There’s much more whole missions in Section 3 than there are in Section 2. So, by way of business-wise, it’s nice to be in both one,” Bruno mentioned. “We’re going to go and bid on those for Lane 1 for any that we predict we’re aggressive for and we’d be good for.”
Bruno mentioned that whereas Lane 1 is meant as a so-called “sandbox” for launch suppliers, he was instructed that due to the variety of missions that will likely be in Lane 1, that the federal government desires larger gamers, like ULA, to bid on a few of these missions as nicely.
“I feel we’ll scoop up a few of these, the place there’s an pressing want and we’re particularly well-suited and perhaps these different gamers simply can’t do it,” Bruno mentioned. “They’ll bid separately on any mission that they’re comfy and have the potential for, which is totally different than being in Lane 2, the place you will have to have the ability to fly every little thing as a way to even bid.”
Waiting for Vulcan launches supporting NSSL missions, ULA is constant work to transform Area Launch Complicated 3 (SLC-3) at Vandenberg Area Power Base from an Atlas 5 pad into one for Vulcan.
He mentioned the Section 3 contract will additional enhance the necessity for West Coast launches of Vulcan past what’s required in Section 2.
“There are extra missions in that timeframe going out of Vandenberg than there are actually. And so, we’re making the most of this quiescent interval to reconfigure the pad for Vulcan, which is totally different from what you noticed us do out right here in Cape Canaveral, the place we reconfigured the pad in between Atlas launches and configured it so as to have the ability to fly both rocket, forwards and backwards,” Bruno mentioned.
“However out at Vandenberg, it’s a tough reduce over. The final Atlas rocket’s already gone out of there,” he added. “So, the pad is down and we’re setting up it for Vulcan uniquely. We’ll be flying out of there and there will likely be extra flights in that window of outing of Vandenberg than there are these days, clearly earlier than the cease.”
Bruno mentioned this new wave of launches that will likely be calling upon Vulcan is only one half of the equation for them as they begin ramping up the business aspect of their enterprise.
“We’re going to be tremendous busy and our greatest problem just isn’t worrying about profitable these contracts. It’s about ramping up and constructing all of the infrastructure and increasing the factories to maintain up with that launch tempo,” Bruno mentioned.
Industrial buildup
The emergence of Vulcan into ULA’s launch fleet begins a key shift for the corporate. It strikes from one targeted predominantly on authorities payloads to 1 with a roughly 50-50 break up with business flights. Bruno mentioned the equation is definitely tipping barely extra in the direction of the business aspect today.
He mentioned about 70 % of their business enterprise is pushed by their 47-launch contract with Amazon to launch its Kuiper satellite tv for pc constellation. The tech large bought the ultimate 9 Atlas 5 flights out there in addition to 38 Vulcan flights.
“For those who requested me at the moment, I might say it’s 48 as a result of we flew their prototype one and two mission as nicely, which was not initially a part of our contract. However they wanted us and so they wanted us in a rush as a result of these spacecraft go to orbit and so they exhibit sure key applied sciences for them,” Bruno mentioned. “And it’s to verify the design path they’re on as they had been getting into into high-rate manufacturing. So it was pressing, if you’ll.”
Initially, the 2 satellites had been set to fly on an ABL RS1 rocket, which was later switched to be a part of the primary Vulcan flight. After the announcement of Vulcan’s debut slipped from a Could 4, 2023, alternative, Amazon pivoted to the Atlas 5 rocket they launched on in September.
“It was a five-month integration of flight, which is fairly brief. The usual is you order your journey to house two years out. And doing it in 5 months was fairly difficult,” Bruno mentioned. “And so, we stepped up and we did it for our buyer, like a great associate, and I’m glad we did as a result of it was, once more, a ravishing mission. However their mission was stellar as nicely.”
Bruno mentioned as soon as Vulcan begins flying Kuiper missions, it would launch 45 satellites with every flight. Atlas 5 rockets will carry 27 satellites every. Bruno mentioned for these mega-satellite constellations, it’s vital to get as many satellites on orbit as rapidly as doable.
“They don’t begin being helpful till you get about 60 to 70 % of that first shell on orbit. So, you’re constructing a variety of satellites and also you’re spending some huge cash and also you’re signing up subscribers, however you’re not offering any service till you break that threshold,” Bruno mentioned. “So, the entrance finish of this for a business utility, like Kuiper, like OneWeb, anyone, Starlink, is you need to quickly get them up there and hit that.”
Bruno mentioned the opposite aspect of the equation for Amazon or different house owners of those mega-constellations is what he described because the “greenback per spacecraft on orbit.”
“The way in which folks would discuss carry within the previous days was dollars-per-kilogram, which by the way in which, was by no means ever significant, till now. Why wasn’t it significant? Trigger the rocket’s the rocket and each mission that flies doesn’t max out its mass functionality, proper?” Bruno mentioned.
“However with small satellites in these mega-constellations, you actually do replenish the entire payload fairing and replenish your mass capability on each, single launch. And the extra you fly, bear in mind I mentioned dollar-per-satellite, that’s the denominator,” he added. “And so, it has a really highly effective impact on the financial attractiveness of the carry a part of the equation.”
To be able to meet the demand from Amazon and future business companions, ULA goes by a big growth of each its manufacturing facility in Decatur, Alabama, in addition to the help infrastructure alongside its provide chain.
On the manufacturing facility aspect, Bruno mentioned they’re placing in a second manufacturing line to fabricate the Centaur 5 higher phases and putting them of their completed items warehouse. They’re additionally within the technique of constructing a second transport barge that will likely be used alongside the Rocketship.
“We’ve let our subcontract to our ship builder, Bollinger. They’re doing design work proper now. Keel will likely be positioned subsequent yr. And so, our mighty fleet of 1 Rocketship will change into two Rocketships, so we’re doubling the fleet,” Bruno mentioned. “It’s truly a bit bit greater than doubling, capability-wise, as a result of it’s a much bigger ship.”
Bruno teased that he already has a reputation picked out for the second ship, however will wait to reveal it at a later date.
He added that on the Cape, the Spaceflight Processing Operations Heart (SPOC), the place the Vulcan Launch Platform (VLP) was constructed, is being transformed right into a second Vertical Integration Facility (VIF). That can permit for 2 rockets, both an Atlas and a Vulcan or two Vulcans, to be prepped for launches concurrently. Bruno mentioned that will likely be operational earlier than the top of 2024.
On the availability chain aspect, Bruno mentioned that Northrop Grumman is “primarily constructing an entire different rocket motor fabrication facility for us.” He additionally famous that Blue Origin’s 200,000-square-foot growth to its rocket engine manufacturing facility in Huntsville, Alabama can also be nearing completion.
Throughout a Could 25, 2023, Huntsville Metropolis Council meeting, a proposal to buy 14.83 acres of land at Cummings Analysis Park close to the present engine manufacturing facility web site was authorized. Blue Origin bought the land for $1,427,378.50, in keeping with Shane Davis, Huntsville’s director of city and financial improvement.
Each Aerojet Rocketdyne, the provider of the RL10 higher stage engines, and L3Harris, which supplies the avionics for Vulcan, are growing their infrastructure as nicely to help the purpose of launching Vulcan 25 occasions per yr.
“We don’t hit the each two week tempo, 25 equal per yr, till the again half of 2025,” mentioned Bruno. “So, when you had been to return into our services and discuss to our folks, you’d hear folks speaking about 25 in 25.”
