«On November 4, 2012, the National Security Agency (NSA) celebrates its 60th anniversary of providing critical information to U.S. decision makers and Armed Forces personnel in defense of our Nation. NSA has evolved from a staff of approximately 7,600 military and civilian employees housed in 1952 in a vacated school in Arlington, VA, into a workforce of more than 30,000 demographically diverse men and women located at NSA headquarters in Ft. Meade, MD, in four national Cryptologic Centers, and at sites throughout the world.»
