What does it actually feel like when the hatch seals shut… and a nuclear submarine disappears beneath the ocean?

In this episode of Interesting Humans, Jeff sits down with former Navy submarine officer Casey Murphy to pull back the curtain on one of the most secretive and psychologically demanding environments on Earth: life aboard a nuclear submarine.

Casey shares what it’s like living hundreds of feet underwater for months at a time, operating inside a machine where a single mistake can have catastrophic consequences. From terrifying fire drills and silent underwater navigation to hurricanes above the ocean and the stress of constant vigilance, this conversation reveals the reality behind America’s nuclear deterrence mission.

The discussion also dives into leadership, faith, pressure, human behavior in confined environments, and the surprising ways the U.S. military uses trained dolphins and sea lions to help protect submarines and ports.

This is a fascinating look into a world very few humans will ever experience.
