About United Launch Alliance
Updated 2026-09-09
United Launch Alliance (ULA) is a premier launch services provider formed as a joint venture between Lockheed Martin and Boeing, delivering reliable access to space for U.S. national security, civil government, and commercial customers. The company successfully launched its next-generation Vulcan Centaur rocket for the first time on January 8, 2024.
Vulcan Centaur is designed to replace ULA's legacy Atlas V and Delta IV rockets while providing competitive pricing for commercial missions. Powered by Blue Origin BE-4 engines, Vulcan addresses Congressional mandates to phase out Russian-made RD-180 engines used on Atlas V. The second Vulcan launch in October 2024 achieved an acceptable orbital insertion for Space Force certification, despite a solid rocket booster anomaly. Space Force certified Vulcan for National Security Space Launch missions in March 2025.
ULA began Vulcan development in 2014 to compete with SpaceX's Falcon 9 while meeting national security requirements. The company has sold more than 70 Vulcan launches including 38 missions for Amazon's Project Kuiper constellation and multiple NSSL missions as part of Phase 2 launch procurement. Production of Atlas V ended in 2024, with the Delta rocket family fully retired.
The company maintains the highest mission success rate in the industry, having delivered hundreds of successful launches for critical military, intelligence, and NASA missions. ULA provides assured access to space for the nation's most important payloads, combining Lockheed Martin and Boeing heritage with next-generation Vulcan capabilities to meet evolving national security and commercial space requirements.
Products and product lines
| Product | Line | Note |
|---|---|---|
| Vulcan Centaur | Launch vehicle | Heavy-lift rocket certified by the U.S. Space Force for National Security Space Launch missions on 26 March 2025, after two demonstration flights; flies in VC0-VC6 configurations with zero to six solid rocket boosters. |
| Atlas V | Launch vehicle (retiring) | ULA ended new Atlas V production and was flying down its remaining inventory of about 13 built vehicles as of February 2026, alongside Vulcan. |
| Centaur V | Upper stage | Vulcan's upper stage; NASA selected Centaur V in March 2026 to replace the planned Exploration Upper Stage on the Space Launch System starting with Artemis 4, targeted for no earlier than early 2028. |
| BE-4 engine | Rocket propulsion | Methane/liquid-oxygen engine built by Blue Origin that powers Vulcan's first stage, ending ULA's reliance on the Russian-made RD-180 used on Atlas V. |
| GEM-63XL solid rocket booster | Solid rocket booster | Northrop Grumman-built strap-on booster used on Vulcan's four- and six-booster configurations; nozzle/motor anomalies on two of Vulcan's four flights to date (October 2024 and February 2026) prompted a Space Force pause on Vulcan NSSL launches. |
Timeline
- 2024 Vulcan Centaur's first flight (Cert-1) launches 8 January from Cape Canaveral carrying the Peregrine lunar lander, beginning NSSL certification. [source]
- 2024 Vulcan's second certification flight (Cert-2) launches 4 October; a solid rocket booster nozzle falls off about 37 seconds into flight, but the vehicle compensates and achieves an acceptable orbital insertion. [source]
- 2025 The U.S. Space Force certifies Vulcan for National Security Space Launch missions on 26 March, after evaluation across 52 certification criteria and two demonstration flights. [source]
- 2025 Vulcan flies its first NSSL mission, USSF-106, on 12 August, carrying NTS-3 and a classified payload to geosynchronous orbit — ULA's 101st national security mission overall. [source]
- 2025 President and CEO Tory Bruno resigns effective 22 December after nearly 12 years leading ULA; interim COO John Elbon is named interim CEO. [source]
- 2026 Vulcan launches the USSF-87 mission on 12 February carrying two GSSAP satellites; one of the four GEM-63XL solid rocket boosters suffers a nozzle burn-through similar to the October 2024 anomaly, though the mission still succeeds. [source]
- 2026 The Space Force publicly halts Vulcan NSSL launches on 26 February pending an investigation into the recurring GEM-63XL solid rocket motor anomaly, with no timeline given for resolution. [source]
- 2026 NASA confirms selection of ULA's Centaur 5 as the new upper stage for the Space Launch System starting with Artemis 4, disclosed in contract documents published 7 March. [source]
