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.
