Overview
- Planned Starliner flights were reduced to four, with two previously slated missions now listed as options.
- Starliner-1 was reclassified as an uncrewed cargo and test mission no earlier than April 2026 to verify propulsion-system safety.
- Boeing's Commercial Crew contract value was lowered by $768 million to $3.732 billion under the revised plan.
- NASA and Boeing say intensive propulsion testing is underway to enable up to two flights next year if readiness is demonstrated.
- The 2024 crewed flight suffered thruster outages and helium leaks, and the two astronauts returned to Earth on SpaceX's Crew Dragon in March.
