What sticks in my mind more than any particular accomplishment of the supersecret National Security Agency is its mammoth size. Only a few miles from my home, I now know, exists a secret Orwellian town where tens of thousands of people live and work. It is surrounded by barbed-wire fences, massive boulders and thick cement barriers, all hidden by tall earthen berms and thick forests. Armed police patrol the boundaries of Crypto City, as this restricted area near the sleepy hamlet of Annapolis Junction, Maryland, is called. Telephoto surveillance cameras peer down. Heavily armed commandos dressed in black and wearing special headgear are on standby in case of trouble.
Beyond lies a forbidden city unlike any other on earth. Its main business is global eavesdropping; its mission is to obtain secrets about foreign enemies and friends alike, and to identify terrorist threats, drug trades, illegal arms sales and so on, all by intercepting voice, phone and radio communications. Using math, cryptology, statistical and other techniques, the NSA can break any code or cipher. The raw material is collected by its spyplanes, ships, satellites and through various other technical means, then is processed by the largest, most powerful electronic brain on earth.
More exact details of this forbidden city remain secret. County officials say they have no idea how many people work there, and no one will tell them. But James Bamford, in his Body of Secrets, offers some clues. The city’s post office distributes 70,000 pieces of mail a day; there are more than 37,000 cars registered there. The local police have more than 700 uniformed officers and their own SWAT team. The city’s consumption of electricity–to power six acres of computers, twenty-five tons of air-conditioning equipment and more than a half-million lightbulbs–costs nearly $2 million per month. In case of power outages, its own power-generating plant can quickly produce enough wattage for a community of more than 3,500 homes. It has its own fire department as well as twenty-three separate alarm systems and 402 miles of sprinklers, feeding 210,000 sprinkler heads. There are theaters, a bank, kindergartens, fitness centers, gas stations, clubs (even its own Gay, Lesbian or Bisexual Employees–“GLOBE”–club). Religious services are held in an unbuggable room, where priest and minister have security clearance far above Top Secret.
At the heart of this community is the NSA headquarters; with 3 million square feet of floor space, it could accommodate the entire US Capitol building four times over. The headquarters building almost metaphorically represents the NSA as well: From the outside, it looks like a stylish modern office building of dark one-way glass. But the real building is hidden under this reflective glass and is protected by a skin of orange-colored copper and unique windows–a thick outer pane, five inches of sound-deadening space, a thin copper screen and an inner pane. The protective shielding is designed to keep all sounds–and indeed any type of electromagnetic radiation–from getting out. It is used throughout much of the city to keep what is said to be the largest body of secrets ever compiled.
