In 1956, as part of a major Agency reorganization, NSA-63, the successor to AFSA-213 and AFSA-211 (another receipt and distribution unit with a high percentage of African-Americans), was dissolved. Many blacks, particularly the tape printers, moved to the new collection organization where they continued to perform the tasks of receiving, converting, and distributing intercept data. A large number of the scanners, however, and many who had worked on the staff of NSA-63 were transferred to various divisions in GENS, Office of General Studies, where they successfully pursued careers as analysts, staff officers, and managers.

As a group, African-Americans suffered from institutional racism at Arlington Hall Station. The segregationist policies of the Army were strictly enforced during the war years and, with the singular exception of Research and Development, were generally followed for years thereafter. It was a white-male-dominated environment that reflected Army racial policies and southern attitudes. African-Americans were routinely hired at lower grades and shuffled into the most menial jobs. They waited longer for fewer promotions and received less training, which constrained their opportunities to assume higher-paying positions.

Early in the 1950s, as the Army's long-standing support for the "separate, but equal" doctrine faded, barriers at AHS began to crumble. African-Americans were hired not only as keypunchers and clerks, but also as analytic aides, linguists, and mathematicians. Some that had entered the Agency through the all-black traffic processing division successfully transferred to organizations that held the promise for challenging, rewarding work in a racially integrated environment. The contributions of whites who acted as agents for change during this period cannot be overlooked or underestimated. African-Americans who started their careers during the early fifties and rose to leadership positions acknowledged the assistance and mentorship of many Caucasians, several of whom, Melba McCarthy, Benson Buffham, and Jack Gurin, were interviewed for this manuscript.

The dissolution of NSA-63 erased a visible and notorious manifestation of racial separation, but questions about equality in recruitment, hiring, assignments, job training, awards, and promotions continued to be raised for years afterwards. Many of those who started at Arlington Hall Station became the Agency's social activists of the 1960s and 1970s at its new location, Fort Meade, Maryland. There, new chapters in the African-American experience at NSA would be written.
