Canada is investing C$33 million into a UK-led partnership including the US and other nations, to buy air defense equipment for Ukraine against Russian threats.
Russia places S1 Pantsir anti-air systems on towers and elevated ramps near Moscow to fend off drone attacks and showcase public safety, according to British intelligence.
The US has announced a new $200 million military aid package for Ukraine, including munitions for air defenses and artillery, anti-tank missiles, and mine-clearing equipment.
Ukraine can't shield its whole territory from Russian missiles, but with layered defenses, 80-90% shoot-down rates, and help from civilians' apps, Ukrainian air defense blocks Russia's air superiority even while reanimating WWII techniques.
The forthcoming fall and winter will be critical for Ukraine and, therefore, Europe. If Russia can destroy Ukraine's air defense, the West will need to reconsider its stand on military intervention.
