TOKYO — A Japanese air force F-35 stealth fighter crashed in the Pacific Ocean during a night training flight and parts of the jet were recovered, the defense ministry said Wednesday.
The pilot is still missing. The F-35A stealth jet disappeared from radar while flying off the eastern coast of Aomori. Parts of the jet were found late Tuesday, the Air Self-Defense Force said.
It went missing about half an hour after taking off from the Misawa air base with three other F-35As.
Defense Minister Takeshi Iwaya told reporters the cause of the crash was not immediately known. He said 12 other F-35s at the Misawa base would be grounded.
The pilot is a man in his 40s, Iwaya said.
Japan started deploying the expensive U.S.-made F-35s since last year, part of its plan to bolster its defense spending and weapons capability in the coming years to counter potential threats from North Korea and China.
Under guidelines approved in December, Prime Minister Shinzo Abe's government plans to buy 147 F-35s, including 105 F-35As, costing about $90 million each.
