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.

Amid fierce European criticism of America's targeted killing program, U.S. and German government officials have long downplayed Ramstein's role in lethal U.S. drone operations and have issued carefully phrased evasions when confronted with direct questions about the base. But the slides show that the facilities at Ramstein perform an essential function in lethal drone strikes conducted by the CIA and the U.S. military in the Middle East, Afghanistan and Africa.
