The Arctic isn’t just ice and maps—it’s a test of national power and supply chains. In this episode, I offer a clear look at the global icebreaker gap: Russia’s eight nuclear heavy ships, China’s growing fleet, and a U.S. plan focused on medium icebreakers that may struggle through four-foot ice. We examine what mediums handle well, why heavy icebreakers still define access and deterrence, and how timing, cost, and reliability will shape leadership in the North.
