Looking out the window of a U.S. Air Force C-12 at Tin City Long Range Radar Site, Alaska, October 1, 2014. The radar sits on top of the highest peak with the living quarters for the team working at the site and the gravel airstrip below. The Tin City LRRS, along with 14 additional radar sites across the rugged terrain of Alaska, scan the airspace above 24 hours a day, seven days a week, 365 days per year, searching for potential threats. Together with the men and women of the Pacific Air Forces Regional Support Center at Joint Base Elmendorf-Richardson, Alaska, this team makes up the unsung heroes that protect our nation’s northern and western borders.
