As the Cold War evolved, American intelligence expanded into the cyber domain with the introduction of computers and satellites. The information obtained from these technological advances spawned a new term: SIGINT, for signals intelligence.  Women have always played major roles in SIGINT collection systems, principally as technicians and analysts. Female engineers, scientists, and mathematicians are major contributors to specialized SIGINT projects representing all facets of today’s technology-driven, intelligence-gathering operations.

While some female Cold Warriors, depending on their work, can be publicly acknowledged, still others remain in the shadows, protecting both “sources and methods” — how the information was obtained and from where or by whom.  Most of these dedicated and patriotic women rightly believed their “secret service” is its own and greatest reward.
