This question may be for Mr. Arel.
There's also the ground-based air defence project, GBAD, that claims to defeat threats posed by rockets, artillery, mortar munitions, air-to-surface missiles and drones with attack aircraft and helicopter relegated to second targets.
Why hasn't our government seen the need to counter threats from high-altitude bombers, given their ability to launch cruise missiles and, more worryingly, hypersonic missiles? That would apply to Canada as well as Latvia.
