Canadian Surfrace Combatant
I think the Canadian surface combatant should be equipped with either AN/SPY-1 or AN/SPY-6 Radar because with newly developing threats from nations like North Korea, Canada may have to deal with incoming ballistic missiles. Also, they should be equipped with extensive ASW hardware as these ships could be operating in an environment like the Sea of Japan or the S. China, even the Atlantic where there will always be potentially hostile submarines patrolling, whether they be from Russia, China, or North Korea. And as usual, they need surface warfare and air warfare capabilities to handle enemy bombers and surface vessels. Finally, I believe Canada may need more than 15 or 16 of these ships due to the fact that their potential rivals continue to expand their navies, which will continue to strain the United States as we try to keep pace with our adversaries(without a budget, lol). It will be necessary for our allies to bolster their naval assets so that we keep the edge over our enemies.
