Vulcan rockets are grounded again — and that matters. Lt. Gen. Philip Garrant, head of the Space Force’s Space Systems Command, said the troubles "absolutely will shape" the Pentagon’s next rocket buy. The launcher is many months from returning to military service after a second solid booster nozzle failure in under two years.
Immediate fallout
This comes at a terrible moment for United Launch Alliance. The Vulcan system, one of two main vehicles the Space Force relies on alongside SpaceX's Falcon 9, has managed just four flights since its debut in January 2024. Two of those launches saw anomalies tied to the rocket's solid rocket boosters, with an exhaust nozzle detaching in October 2024 and a similar malfunction appearing again in February 2026. In both cases the vehicles still reached their target orbits, but that doesn't erase the engineering and operational questions now dogging the programme.
The Space Force has almost 70 launches queued to get a ride to orbit. Some of those missions are national-security satellites; others support military comms and navigation. Having a workhorse launcher out of service for months compresses options and raises tricky scheduling calls for the Space Systems Command, which buys and manages many of those missions.
Garrant put it bluntly: his office is the one that accepts the risk when a rocket flies. "From my role, as essentially the person who accepts the risk of launching the rocket, it certainly shapes my decision space," he said. That responsibility, he added, will feed directly into how the Pentagon evaluates proposals the next time it asks companies to bid for guaranteed military launch slots.
What went wrong with Vulcan?
Investigations into the nozzle incidents are ongoing, and the immediate cause points toward the boosters. Those motors are supplied by Northrop Grumman, while Vulcan itself is built and operated by United Launch Alliance.
The nozzle failures suggest either a design weakness or a production or quality-control problem at the booster supplier.
One recurring hardware fault can trigger a string of problems across testing, certification and scheduling. Safety reviews slow down production. Test schedules get longer. Certification milestones slip. And for customers — mainly the Space Force for these missions — that means calendars get jammed and contingency plans get expensive.
For years ULA was seen as the conservative, steady choice for national-security launches. Vulcan was supposed to be the next step forward. Instead, the program is being measured by rare but high-visibility failures. Reputation damage isn't tallied on a balance sheet, but it shows up in procurement conversations and in which vendors get the benefit of the doubt when a slip occurs.
Who stands to gain — and who loses
SpaceX has repeatedly demonstrated a high flight cadence with Falcon 9 and has been a frequent option for Space Force missions. That operational record makes SpaceX an obvious place to shift flights when Vulcan is unavailable. But shifting dozens of launches isn't trivial: launch pads, range availability and contractual terms all matter.
Still, companies with proven flight histories and spare capacity tend to be preferred when reliability is the primary yardstick. If the Pentagon's procurement teams decide they need to minimise programme risk, that could tilt future contracts toward firms with long, uninterrupted flight records.
On the other side, ULA faces a difficult sales pitch. United Launch Alliance must show it has found the root cause and fixed it, and it will need repeatable, demonstrable results to rebuild trust. That will likely mean extra testing and possibly design or manufacturing changes for the solid boosters — steps that take time and money.
Procurement and policy implications
The next round of Pentagon launcher competitions isn't just about price. Reliability, demonstrated performance and the ability to meet schedule windows for national-security payloads carry a lot of weight. Garrant's remarks indicate risk acceptance — who will sign off on a flight — will be a prominent factor in evaluations.
Procurement teams will focus on vendors that can show both technical competence and solid program management. That includes supply-chain resilience, transparency on root-cause investigations and rapid corrective action. We may see new contracts spell out stricter performance milestones and clearer penalties for missed schedules.
Expect insurers and customers to reassess pricing and availability terms for launches. Customers don't just pay for the ride; they pay for the assurance that a satellite will actually reach orbit on time. If Vulcan can't provide that certainty, the financial penalties for missed launches — or the premium for alternate lift — will be part of the calculus.
Wider industry ripple effects
Although the issue started with hardware, its effects ripple through the whole launch industry. Suppliers such as Northrop Grumman will face intense scrutiny from both regulators and customers. Testing facilities will be booked for longer. Competing launch providers will get calls from customers looking to reshuffle manifest assignments.
And while the Vulcan incidents didn't cause mission loss, they did create an atmosphere of wariness. Program managers and national-security planners tend to be cautious — they prefer a small delay with a validated fix over a quick return to flight without full confidence in the corrective steps. That conservative default will shape decisions in upcoming procurement rounds.
Industry players also watch what the Space Force does. If the military shifts a noticeable chunk of missions to another provider, that's a clear signal the department is prioritising flight history over vendor diversity. Conversely, if ULA can demonstrate fixes and a safe return to flight, it could reclaim launches that might otherwise have migrated elsewhere.
What to watch next
There are a few specific markers to follow. One: the outcome of the failure investigation and whether it finds a discrete manufacturing flaw or a deeper design issue. Two: ULA's timeline for corrective action and test flights — how many successful launches will it need before procurement officials restore confidence? Three: how the Space Force recalibrates its manifest and whether it formally moves missions to other providers.
One industry view is that the Vulcan could be off the military manifest until late in the year; others expect an extended pause. Regardless of the exact timetable, the program's recent troubles are guaranteed to feature in the Pentagon's next request for proposals and in the technical evaluation criteria that follow.
For programme managers, the lesson is simple: hardware reliability and the ability to recover from setbacks matter as much as cost. That lesson will shape procurement choices and vendor strategies for years to come.
