A U.S. vessel is close to the crash site. The black box battery will die before that, making it harder to locate the aircraft. It is designed to link up other assets, what the Air Force calls "linking sensors to shooters."
The BBC describes the plane as the U.S. Navy's first "low observable" carrier-based aircraft, "which enables it to operate undetected in enemy airspace." And it's also "the most powerful fighter engine in the world," flying at speeds up to 1,200 mph, or Mach 1.6.The $100 million warplane crash-landed onto the deck of an aircraft carrier and then fell into the water.
