This means that of the Army’s 10,500-person-strong code-breaking force, nearly 70 percent was female. Similarly, at the war’s outset the U.S. Navy had a few hundred code breakers, stationed mostly in Washington but also in Hawaii and the Philippines. By 1945, there were 5,000 naval code breakers stationed in Washington, and about the same number serving overseas. At least 80 percent of the Navy’s domestic code breakers—some 4,000—were female. Thus, out of about 20,000 total American code breakers during the war, some 11,000 were women.
