The Defense Ministry has retrieved part of the flight data recorder from a F-35A stealth fighter that went missing last month, but it was heavily damaged and also did not include a storage device to record speed and altitude data, Defense Minister Takeshi Iwaya told reporters Tuesday.
The discovery on the sea floor, the exact location of which has been withheld for security reasons, is therefore unlikely to help determine the cause of the crash.
What looked like some parts of the stealth fighter — which cost more than ¥10 billion — were also spotted on the sea floor, about 1,500 meters below the surface. The Defense Ministry plans to salvage them, said a public relations officer with the Air Self-Defense Force in Tokyo.
