The U.S. Navy has not confirmed the status of the helicopter. It is reported that aircraft may also disappear from flight tracking websites due to limited signal coverage or the crew turning off the transponder.

According to the U.S. Navy, its primary missions include detection and attack of submarines and surface ships, electronic warfare, and command and control. (CCTV International News)
