HOW THE NAVY'S NEW ANTI-SUBMARINE AIRCRAFT SEES UNDER THE WAVES
"The P-8 Poseidon, the most advanced search aircraft in the world, has been a part of the US Navy for just a year now. This infographic lays out the converted Boeing 737's capabilities in detecting enemy submarines, surface ships, and other aircraft.
"Large metal objects like submarines create variances in the Earth's magnetic field, which the Poseidon P-8 is tuned into, thanks to a tailpiece called the Magnet Anomaly Detector (MAD).
"Alternatively, the plane can drop sonobuoys (that's sonar buoys) from on high, allowing the crew inside to measure the sound propagation that surrounds these underwater units, just as a submarine or warship typically would. The P-8 can send out more than 100 of these yard-long sonobuoys in a single flight.
(Magnetic anomalies have been linked to everything from vortices, to ancient settlements built on top of these anomalies.)
