Global conflicts in 2020 have highlighted the unexpected employment of advanced ballistic missiles and unmanned aerial vehicles by developing military powers. The development of ballistic missiles by Iran, or the export of advanced drones by Turkey, are ultimately the result of the American-led revolution in military affairs that, during the Gulf War, established the potential of precision guided weapons and reconnaissance systems. In response, America’s competitors have adapted their military doctrines and developed weapons designed to both counter and copy the West’s technological advantages. As the Government of Canada implements its defence policy—Strong, Secure, and Engaged—it has promised to procure a ground-based air defence system for the Canadian Armed Forces. Careful consideration and analysis are required, however, to ensure that Canada procures the best possible solution given limited funding and a wide array of potential threats.
