Contemporary nuclear submarines can dive under the ice for a long time, but if they launch missiles under the ice, they must break the ice and float up, which leads to mechanical problems. Diving experts are inspired by the fact that whales break ice and breathe every 10 minute. In terms of the podium coaming and superstructure protruding from the top of the submarine, they strengthened the material strength, simulated the whale back, and truly achieved the "whale back effect" when breaking the ice.
