All the activities on Alaska’s three weapons training ranges – incorporating more than 68,000 square miles (180,000 km²) of airspace, 28 threat systems, and 225 targets for range and exercise operations – are planned and controlled by 353rd CTS personnel. The three tactical ranges supervised by the squadron’s range division are Blair Lakes, Yukon and Oklahoma. The Blair Lakes Conventional Range is located about 26 miles southwest of Eielson AFB. Isolated in a sub-Arctic tundra environment, this range is manned continuously and is normally accessible only by helicopter.
