U.S. Defense Secretary Robert Gates peers toward the top of a missile housed underground at Fort Greely on Monday, June 1, 2009, during a tour of the U.S. Army base with U.S. Sen. Mark Begich, D-Alaska. The non-explosive missiles house an exoatmosphereic kill vehicle within them which, once in orbit, intercepts and destroys enemy ballistic missiles. Fort Greely is located about 110 miles south of Fairbanks near Delta Junction, Alaska. AP Photo logo AP Photo 5 months ago
