A TOP-SECRET U.S. intelligence document obtained by The Intercept confirms that the sprawling U.S. military base in Ramstein, Germany serves as the high-tech heart of America’s drone program. Ramstein is the site of a satellite relay station that enables drone operators in the American Southwest to communicate with their remote aircraft in Yemen, Somalia, Afghanistan and other targeted countries. The top-secret slide deck, dated July 2012, provides the most detailed blueprint seen to date of the technical architecture used to conduct strikes with Predator and Reaper drones.
