The U.S. Navy, in the search for the missing Malaysian Airlines jet, will be unveiling a black box locator AUV (autonomous underwater vehicle) to their arsenal as the search continues.
The UAV dives down into the ocean, “listening” for pings coming from the black box. It can then triangulate these pings and hone in on the signal, allowing search teams to find the object.
Poor weather conditions have caused the search effort to delay, but these AUVs can dodge poor above water conditions by diving to a depth as low as 20,000 feet below the surface of the ocean. The Towed Pinger Locator (TPL 25) is one of several autonomous vehicles that are at the disposal of U.S. armed forces.
