Workers pull down old radar structures that were part of the now-defunct Ballistic Missile Early Warning System at Clear Air Force Station in October. The Cold War-era BMEWS was removed and recycled to make way for new construction. About a billion dollars’ worth of work is under way at Clear, related to installation of the a new radar system that will provide much greater coverage for such missile-defense facilities as the base at Fort Greely.
