Boeing CST-100 Starliner
Boeing's CST-100 Starliner is a partially reusable crew-transport spacecraft developed under NASA's Commercial Crew Program. Boeing built three crew modules: Spacecraft 1 for the pad-abort test and reusable Spacecraft 2 and 3 for orbital missions. Three orbital flight tests were completed from 2019 through 2024, but Starliner remains uncertified while NASA and Boeing resolve propulsion, helium-leak, parachute, qualification, and program-management findings. The next planned flight is an uncrewed cargo validation mission whose launch opportunity remains under review.

- Variant Notes
- Twenty exact OMAC engines on the Starliner service module provide orbital maneuvering and deorbit capability; RCS and launch-abort systems are intentionally excluded from this bounded entry.
- Name
- CST-100 Starliner service-module OMAC configuration
- Notes
- Applies only to the operational CST-100 Starliner service-module OMAC system. The 28 service-module RCS thrusters, 12 crew-module RCS thrusters, and four launch-abort engines remain separate or unmodeled until each exact system boundary is independently sourced; no early 24-OMAC test configuration is substituted.
