Quantum Oceans: How Cold-Atom Gravity Sensors Could Transform Submarine Warfare and Undersea Surveillance
For more than seventy years, the strategic balance of naval warfare has depended on one fundamental assumption: deep oceans provide concealment. Nuclear-powered submarines carrying conventional and nuclear weapons have relied on the vast acoustic complexity of the ocean to remain hidden from adversaries. Traditional anti-submarine warfare evolved around sound propagation, passive hydrophones, active sonar pings, magnetic anomaly detection, and increasingly sophisticated acoustic analysis.
