TOKYO 鈥� Japan said Tuesday it had recovered some debris from a stealth fighter jet that crashed in April, but was still looking for the 鈥渁ll-important鈥� memory that could offer clues into the accident.
Nearly a month after the high-tech F-35A plummeted into the sea off the coast of northeastern Japan, neither the pilot鈥檚 body, nor the plane鈥檚 fuselage have been found, said Defense Minister Takeshi Iwaya.
Experts say Japan and the U.S. are keen to prevent debris from the plane being recovered by Russia or China, with Iwaya admitting last month there were 鈥渁 significant amount of secrets that need to be protected鈥� on board.
Some debris, including a part of the flight data recorder, were recovered 鈥渙n or after May 3鈥�, Iwaya said, adding: 鈥淭he Defense Ministry is studying (the parts), but at this point, the all-important memory (of the flight data recorder) has not been recovered.鈥�
The fighter jet went missing on April 9 while flying 135 kilometers (85 miles) east of Misawa, northeastern Japan, on a training mission.
The plane lost contact about 30 minutes after taking off from Misawa Air Base with three other aircraft.
It was the first reported case of a crash by an F35-A, according to Japan鈥檚 Air Self-Defence Force.
Japanese and U.S. search crews have already found the jet鈥檚 tail.
U.S. and Japanese troops have used data from a Japanese seabed research ship along with a US-chartered special 鈥渄iving support鈥� vessel for deep-sea operations to pull up the newly discovered parts, Iwaya said.
Japan is deploying F35-As, each of which costs more than 10 billion yen ($90 million), to replace its ageing F-4 fighters.
They are a key part of Prime Minister Shinzo Abe鈥檚 efforts to upgrade the nation鈥檚 military capacity to meet changing power dynamics in East Asia, with China rapidly modernizing its military.听 /muf
