Apollo Command and Service Module Block I

Block I was the first production configuration of the Apollo Command and Service Module. CSM-009 and CSM-011 flew suborbital Saturn IB qualification missions in 1966; CM-012 was destroyed in the Apollo 1 ground fire; and CSM-017 and CSM-020 flew the uncrewed Apollo 4 and Apollo 6 Saturn V qualification missions. No Block I spacecraft carried a crew in flight.

    Notes
    The Block I configuration records the exact AJ10-137 Service Propulsion System established for the early uncrewed Apollo flight articles. Block I RCS package counts and subsystem boundaries are not added here because the available Block I sources do not establish them with the precision required to reuse the Block II quad/subsystem configuration; those details remain intentionally unmodeled.
