The Apollo Command and Service Module (CSM) contract was award to North American Aviation on November 28, 1961. At the time, the plan was to land the entire CSM on the lunar surface via the direct ascent and the initial design did not include a means to dock with another spacecraft. Later on this was changed to the lunar orbit rendezvous and lunar landing would be preform via the Lunar Module. This required a major redesign of the CSM and in 1963, NASA decided the most efficient way to keep the program on track was to proceed with the development in two versions:

Block I: the preliminary version for early low Earth orbit test flights only.

Block II: the new lunar-capable version, which included a docking hatch, incorporating weight reduction and lessons learned from the Block I.

The CSM Block I was to be used for all uncrewed Saturn IB (AS-201 & AS-202) and Saturn V (AS-501 & AS-502) test flights, plus two manned missions. This was changed to only one in late 1966, being Apollo AS-204, aka Apollo 1. After the Apollo 1 fire all manned missions were to use the improved Block II versions.

Block I Command and Service Modules produced:

CSM-001: systems compatibility test vehicle, used on propulsion tests at White Sands Missile Range. Completed tests on September 7, 1968. CSM scrapped.

CSM-002: used for powered on tumble abort tests, flew on A-004 Little Joe II, January 20, 1966, at White Sands Missile Range. Modified to 002A.

CM-002A: used to in land drop tests. Modified to 002B

CSM-007: various tests including acoustic vibration and drop tests, and used as a ground test vehicle. CM modified to 007A. SM used for fitcheck of docked model facility, current location is unknown.

CM-007A: used by Astronauts for water egress training, water-survival training and extended recovery training in the Gulf of Mexico. CM was refitted with Block II improvements. Underwent testing for Skylab at the McKinley Climatic Laboratory, Eglin AFB, Florida, 1971–1973. On display.

CM-007A is on display at the Seattle Museum of Flight, Seattle, WA.

CSM-008: complete systems spacecraft used in thermal vacuum tests. CM modified to 008A, SM offered to Smithsonian but declined (August 1973), later scrapped by Rockwell International at Downey, CA May 1977.
