SpaceX Hits 33-Flight Booster Record as Vulcan Faces National Security Launch Pause
The U.S. Space Force halted Vulcan Centaur missions after recurring solid rocket booster anomalies, while SpaceX extends its reusability lead and Blue Origin struggles with lunar lander development delays.
SpaceX set a new reusability benchmark on 21 February when a Falcon 9 first-stage booster completed its 33rd flight, extending the operational gap between the company and rivals still working through certification challenges. The milestone came during dual Starlink launches from California and Florida, demonstrating a cadence and reliability that now defines the commercial launch market. As of 27 February, SpaceX has successfully landed Falcon 9 boosters 562 times, with individual boosters flying as many as 33 missions.
The achievement contrasts sharply with developments elsewhere in the U.S. launch sector. The U.S. Space Force has placed an indefinite halt on all national security missions aboard United Launch Alliance’s Vulcan Centaur, following a repeat anomaly with the rocket’s solid rocket boosters. The pause affects a critical certification pathway for ULA, which secured $5.3 billion for 19 missions under the Space Force’s National Security Space Launch program.
Vulcan’s Certification Crisis
ULA’s second certification flight on 4 October 2024 appeared successful until video showed what appeared to be a burn-through above the nozzle of one of the solid rocket boosters, causing the nozzle to detach in a shower of sparks and debris. Despite achieving precise orbital insertion, the observation marked the second time in just four flights that ULA ran into a similar issue with the Northrop Grumman-supplied GEM-63XL boosters.
According to Spaceflight Now, Vulcan completed certification in March 2025, with ULA planning 16 to 18 missions in 2026. The grounding derails that schedule and raises questions about whether the rocket can meet national security launch commitments that require demonstrated reliability.
Blue Origin’s Lunar Bottleneck
While ULA grapples with booster reliability, Blue Origin faces mounting pressure on its NASA Artemis commitments. In January, Blue Origin announced it would pause New Shepard suborbital tourism flights for at least two years to shift resources toward lunar landing capabilities. The company holds a $3.4 billion contract for the Blue Moon Mark 2 human lander, with delivery timelines increasingly uncertain.
Blue Origin’s New Glenn rocket, critical for launching lunar hardware, has flown only twice. Its maiden flight occurred on 16 January 2025, with the first stage achieving its first successful landing on 13 November 2025. The company’s Blue Moon Mark 1 robotic lander was originally planned to land in 2024 and has been delayed to 2026.
The delays cascade through NASA’s lunar architecture. The Griffin-1 mission was designed to transport NASA’s VIPER rover, but delays stemmed largely from Blue Origin’s BE-4 engine development and readiness issues that also affected ULA’s Vulcan program, as both systems rely on the same propulsion technology.
Blue Origin supplies the BE-4 engines that power both its New Glenn rocket and ULA’s Vulcan Centaur. Engine delivery delays in the early 2020s pushed back Vulcan’s debut by years, illustrating how supplier bottlenecks ripple through the entire launch sector. SpaceX, by contrast, manufactures its Merlin and Raptor engines in-house, maintaining tighter control over production schedules.
SpaceX’s Cost and Cadence Advantage
The numbers clarify the competitive chasm. SpaceX conducted roughly 80% of U.S. space launches in 2025, growing its market share fourfold in 17 years. According to Ars Technica reporting cited by Spaceflight Now, SpaceX’s internal costs for launching a reusable Falcon 9 rocket are $15 million, compared to listed prices of $67 million.
The cost differential versus competitors is stark. ULA’s Vulcan carries 27,200 kg to LEO at a base cost of $110 million, translating to around $4,044 per kg, focused on missions to geostationary orbit where the Vulcan excels. Blue Origin’s New Glenn can carry 13 metric tons to GTO at an estimated $68 million per flight, while Rocket Lab’s Neutron is expected around $55 million for dedicated flights.
| Vehicle | LEO Capacity | Cost per kg | Status |
|---|---|---|---|
| Falcon 9 (reused) | 22,800 kg | ~$660 | Operational |
| Vulcan Centaur | 27,200 kg | ~$4,044 | Grounded (NSS) |
| New Glenn | 45,000 kg | ~$1,511 | 2 flights |
| Neutron | 13,000 kg | ~$4,231 | Development |
SpaceX conducted 165 Falcon family vehicle launches in 2025, a new annual launch record. The company has demonstrated 562 successful booster landings with individual boosters flying as many as 33 missions, creating a fleet of flight-proven hardware that drives down per-launch economics while maintaining a 99.82% success rate for the Falcon 9 Block 5 variant.
What to Watch
The Space Force’s Vulcan review timeline will determine whether ULA can fulfill its 2026 national security launch manifest or faces contract penalties. Blue Origin must demonstrate New Glenn reliability across multiple flights and deliver Blue Moon hardware on schedule to retain its Artemis role—NASA acting administrator Sean Duffy has signaled openness to reopening the Artemis 3 contract if SpaceX continues falling behind on Starship HLS development.
For SpaceX, the test is whether competitors can narrow the cost and cadence gap before the company’s dominance calcifies into structural market control. With internal launch costs at $15 million and 80% U.S. market share, the question is less whether rivals can catch up than whether a viable competitive ecosystem can survive at all. The Vulcan grounding and Blue Origin’s lunar delays suggest the answer leans negative.
