Early in February, Rocketdyne had completed the significant portion of the qualification test program on the OAMS and reentry control systems as configured for spacecraft Nos. 3, 4, and 5; however, some further testing extended final qualification until mid-April. OAMS component qualification for the spacecraft 6 (and up) configuration was achieved early in June. The total ground qualification of all Gemini spacecraft liquid propellant rocket systems was completed in August with the system qualification of the OAMS in the spacecraft 6 configuration.
