By 1974, ADC had inactivated the rest of its flying radar evaluation units and wanted to replace the 4677th, which was a Major Command controlled (MAJCON) unit with and Air Force controlled (AFCON) squadron, whose history could be continued if it were inactivated. As a result, the 4677th was inactivated and the 17th Defense Systems Evaluation Squadron was activated in its place. The continuity between the units was shown when the 17th decided to retain the 4677th's patch, changing only the number in the scroll. The squadron remained active until 1979 when it was inactivated as part of the reduced need for aerial evaluation of military radars as the Joint Surveillance System utilizing radars shared with the
