Two crew members were able to eject and have been rescued by helicopter, the US Navy says.
A US Navy fighter jet has crashed in the Philippine Sea, south of the Japanese island of Okinawa.
The F/A-18 Hornet was conducting routine operations when it « experienced a mechanical issue » that forced the two crew to eject, the US 7th Fleet said.
The pair were rescued from the water in good condition and were being evaluated on board the USS Ronald Reagan aircraft carrier, it added.
Okinawa hosts US military bases and thousands of personnel.
Japan’s coastguard sent an aircraft to check if there was « any debris or floating oil » as a result of the crash, a spokesperson told the AFP news agency.
