Sonobuoy: How Does This Portable SONAR System Bust Enemy Submarines?

Submarines are among the most feared weapons in naval warfare, largely because they can vanish beneath the waves and strike without warning. But how do militaries detect these stealthy underwater threats from thousands of feet up in the air? In this video, we explain how sonobuoys work as portable SONAR systems deployed by aircraft and ships to hunt enemy submarines. We cover the history of submarine stealth from World War-era U-boats to modern detection technology, the three types of sonobuoys (active, passive, and special-purpose), and how data is relayed back to aircraft for analysis.
