| Summary | ULA's next-generation medium-heavy rocket replacing Atlas V. Powered by two BE-4 engines on the first stage and a cryogenic Centaur V upper stage. NSSL-certified March 2025; first NSSL mission USSF-106 flew Aug 13, 2025. Paused by the Space Force after the USSF-87 SRB nozzle anomaly (Feb 12, 2026), with return to flight expected ~late 2026. | Firefly Aerospace's two-stage small-lift rocket powered by four Reaver engines at sea level and one Lightning engine in vacuum. Also provides launch services for NASA's CLPS programme (Blue Ghost lander launched on Falcon 9). FLTA007 'Stairway to Seven' succeeded Mar 11, 2026. | ULA's workhorse since 2002 and the longest-serving active US rocket. Launched Mars Science Laboratory (Curiosity), OSIRIS-REx, Solar Orbiter, Lucy, New Horizons, and the Boeing Starliner. Production ended in 2024 and ULA no longer sells the vehicle, but it continues flying a sold-out backlog of Starliner and Amazon Leo missions into the late 2020s. |
