How the Navy learned to hear submarines from 3,000 miles away—and how submarines learned to vanish. This video explores the physics of underwater acoustic warfare, from the discovery of the SOFAR channel to the evolution of modern stealth engineering. Discover how wave refraction, deep-ocean mathematics, and fluid dynamics completely rewrote the rules of submarine detection.
