Last October, United Launch Alliance started stacking its third Vulcan rocket on a mobile launch platform in Florida in preparation for a mission for the US Space Force by the end of the year.<\/p>\n

That didn\u2019t happen, and ULA is still awaiting the Space Force\u2019s formal certification of its new rocket, further pushing out delivery schedules for numerous military satellites booked to fly to orbit on the Vulcan launcher.<\/p>\n

Now, several months after stacking the next Vulcan rocket, ULA has started taking it apart. First reported by Spaceflight Now, the \u201cde-stacking\u201d will clear ULA\u2019s vertical hangar for assembly of an Atlas V rocket\u2014the Vulcan\u2019s predecessor\u2014to launch the first batch of operational satellites for Amazon\u2019s Kuiper Internet constellation.<\/p>\n

This involves removing the rocket\u2019s Centaur upper stage, interstage adapter, and booster stage from its launch mount. ULA\u2019s facilities at Cape Canaveral Space Force Station, Florida, can only handle stacking one rocket at a time. A second assembly building will double this capacity when it comes online later this year.<\/p>\n

ULA hoped to launch as many as 20 missions in 2025, with roughly an even split between its new Vulcan rocket and the Atlas V heading for retirement. That would require around one launch every two and a half weeks. Six weeks into 2025, ULA\u2019s first launch of the year is still a month or more away.<\/p>\n

More than crossing T\u2019s and dotting I\u2019s<\/h2>\n

The laborious process of certifying a new rocket or spacecraft involves numerous reviews and metaphorical stacks of paperwork. The Space Force\u2019s objective with certifying the Vulcan rocket is ensuring it will provide a reliable ride to orbit for the military\u2019s most sensitive and expensive satellites. These include spy satellites, missile warning sentinels, and spacecraft for the Global Positioning System.<\/p>\n

In 2020, the Pentagon awarded ULA and SpaceX multibillion-dollar \u201cPhase 2\u201d contracts to share responsibilities for launching dozens of national security space missions. At that time, these launches were projected to fly by the end of 2027, although that\u2019s unlikely to happen now.<\/p>\n

The Space Force awarded ULA 26 missions worth $4.5 billion under the Phase 2 contract, while 22 missions went to SpaceX\u2019s Falcon 9 and Falcon Heavy. SpaceX started delivering on its Phase 2 contract in January 2023. The first of ULA\u2019s Phase 2 missions launched last year on an Atlas V rocket, and 25 more are slated to fly on Vulcan.<\/p>\n

Pentagon officials haven\u2019t been pleased with ULA\u2019s progress on the Vulcan rocket. The most evident sign of the discontent came in the form of a letter last year to Boeing and Lockheed Martin, ULA\u2019s co-owners.<\/p>\n

Frank Calvelli, then the Air Force\u2019s assistant secretary for space acquisition and integration, wrote that he was \u201cgrowing concerned with ULA\u2019s ability to scale manufacturing of its Vulcan rocket and scale its launch cadence to meet our needs.\u201d<\/p>\n

Development setbacks delayed the first Vulcan launch by about four years before ULA successfully completed the rocket\u2019s first demonstration flight in January 2024. At that time, ULA expected to be ready to launch the first military mission on the Vulcan rocket in mid-2024, plus two more by the end of the year. Those missions are still waiting for their ride to space.<\/p>\n

\u201cCurrently there is military satellite capability sitting on the ground due to Vulcan delays,\u201d Calvelli wrote.<\/p>\n

A second Vulcan test flight launched on October 4, and while the rocket reached its targeted orbit, it overcame a malfunction in one of the rocket\u2019s two solid rocket boosters, which lost its exhaust nozzle moments after liftoff.<\/p>\n

The problem prompted an engineering investigation in parallel with the Space Force\u2019s certification process, which required two successful flights before clearing Vulcan for operational service. This eliminated any chance of launching the first Vulcan flight for the Space Force by the end of 2024.<\/p>\n

Tory Bruno, ULA\u2019s CEO, told reporters in December that engineers have a \u201cpretty good idea of what happened\u201d with the Northrop Grumman-built solid rocket booster, and boosters already in ULA\u2019s inventory will require \u201cminor modifications\u201d to fix the problem. \u201cThere are insulators that failed that are bonded to the inside of the shell that becomes the nozzle, and we recovered parts of those,\u201d Bruno said.<\/p>\n

The first national security mission on Vulcan, designated USSF-106, is set to deploy an experimental navigation satellite for the Air Force Research Laboratory.<\/p>\n

ULA crews at Cape Canaveral have already stacked the next Vulcan rocket on its mobile launch platform in anticipation of launching the USSF-106 mission. But with the Space Force\u2019s Space Systems Command still withholding certification, there\u2019s no confirmed launch date for USSF-106.<\/p>\n

So ULA is pivoting to another customer on its launch manifest.<\/p>\n

Amazon\u2019s first group of production satellites for the company\u2019s Kuiper Internet network is now first in line on ULA\u2019s schedule. Amazon confirmed last month that it would ship Kuiper satellites to Cape Canaveral from its factory in Kirkland, Washington. Like ULA, Amazon has run into its own delays with manufacturing Kuiper satellites.<\/p>\n

\u201cThese satellites, built to withstand the harsh conditions of space and the journey there, will be processed upon arrival to get them ready for launch,\u201d Amazon posted on X. \u201cThese satellites will bring fast, reliable Internet to customers even in remote areas. Stay tuned for our first launch this year.\u201d<\/p>\n

Amazon and the Space Force take up nearly all of ULA\u2019s launch backlog. Amazon has eight flights reserved on Atlas V rockets and 38 missions booked on the Vulcan launcher to deploy about half of its 3,232 satellites to compete with SpaceX\u2019s Starlink network. Amazon also has launch contracts with Blue Origin, which is owned by Amazon founder Jeff Bezos, along with Arianespace and SpaceX.<\/p>\n

The good news is that United Launch Alliance has an inventory of rockets awaiting an opportunity to fly. The company plans to finish manufacturing its remaining 15 Atlas V rockets within a few months, allowing the factory in Decatur, Alabama, to focus solely on producing Vulcan launch vehicles. ULA has all the major parts for two Vulcan rockets in storage at Cape Canaveral.<\/p>\n

\u201cWe have a stockpile of rockets, which is kind of unusual,\u201d Bruno said. \u201cNormally, you build it, you fly it, you build another one\u2026 I would certainly want anyone who\u2019s ready to go to space able to go to space.\u201d<\/p>\n

Space Force officials now aim to finish the certification of the Vulcan rocket in late February or early March. This would clear the path for launching the USSF-106 mission after the next Atlas V. Once the Kuiper launch gets off the ground, teams will bring the Vulcan rocket\u2019s components back to the hangar to be stacked again.<\/p>\n

The Space Force has not set a launch date for USSF-106, but the service says liftoff is targeted for sometime between the beginning of April and the end of June, nearly five years after ULA won its lucrative contract.<\/p>\n","protected":false},"excerpt":{"rendered":"
