The Multibillion-Dollar U.S. Spy Agency You Haven’t Heard of

How President Trump might turn an all-seeing spy apparatus on innocent American citizens.

On a heavily protected military base some 15 miles south of Washington, D.C., sits the massive headquarters of a spy agency few know exists. Even Barack Obama, five months into his presidency, seemed not to have recognized its name. While shaking hands at a Five Guys hamburger restaurant in Washington in May 2009, he asked a customer seated at a table about his job. “What do you [do]?” the president inquired. “I work at NGA, National Geospatial-Intelligence Agency,” the man answered. Obama appeared dumbfounded. “So, explain to me exactly what this National Geospatial…” he said, unable to finish the name. Eight years after that videotape aired, the NGA remains by far the most shadowy member of the Big Five spy agencies, which include the CIA and the National Security Agency.
Despite its lack of name recognition, the NGA’s headquarters is the third-largest building in the Washington metropolitan area, bigger than the CIA headquarters and the U.S. Capitol.
Completed in 2011 at a cost of $1.4 billion, the main building measures four football fields long and covers as much ground as two aircraft carriers. In 2016, the agency purchased 99 acres in St. Louis to construct additional buildings at a cost of $1.75 billion to accommodate the growing workforce, with 3,000 employees already in the city.
The NGA is to pictures what the NSA is to voices. Its principal function is to analyze the billions of images and miles of video captured by drones in the Middle East and spy satellites circling the globe. But because it has largely kept its ultra-high-resolution cameras pointed away from the United States, according to a variety of studies, the agency has never been involved in domestic spy scandals like its two far more famous siblings, the CIA and the NSA. However, there’s reason to believe that this will change under President Donald Trump.http://foreignpolicy.com/2017/03/20/the-multibillion-dollar-u-s-spy-agency-you-havent-heard-of-trump/
