Royal Canadian Air Force CF-18 Hornet, United States Air Force F-16 Fighting Falcon, and United States Air Force F-22 Raptor fight jets fly in formation with two United States Air Force B-52 Stratofortress over Alaska, during Exercise Amalgam Dart 21-1, June 15, 2021. Exercise Amalgam Dart will run from June 10-18, 2021, with operations ranging across the Arctic from the Beaufort Sea to Thule, Greenland. Amalgam Dart 21-01 provides NORAD the opportunity to hone continental defense skills as Canadian and U.S. forces operate together in the Arctic. A bi-national Canadian and American command, NORAD employs a network of space-based, aerial and ground-based sensors, air-to-air refueling tankers, and fighter aircraft, controlled by a sophisticated command and control network to deter, deny and defeat aerospace threats that originate outside or within our borders.
