Japan's Self-Defense Force has confirmed that one of its F35A fighter jets has crashed into the sea off Aomori Prefecture, northern Japan.
Officials say the pilot was flying with three other planes of the same model on a training mission on Tuesday. They say there were no reports of problems before contact was lost.
Thirteen F35As are currently deployed at Misawa Air Base in northern Japan. It's set to become the country's next-generation mainstay fighter.
