Without plan for new submarines Canada faces defense gap in the Arctic
National Post: "The RCN has been clear that it sees an Arctic ice capability as necessary for a future submarine replacement. But without significant advances in diesel-electric submarines or new air independent propulsion hybrids that can recharge batteries through fuel cells, nuclear remains the only game in town. The previous attempt at nuclear partially failed over American reluctance to transfer nuclear submarine know-how to Canada. However, with the creation in September of the AUKUS defence pact, the US and UK are set to assist Australia in procuring nuclear-powered submarines. Of course, the cost of this acquisition will likely prove significant for Australia."
