Algosensey Quantitative Think Tank Center-Black Hawk helicopter carrying 10 crew members crashes into ocean, Japan's army says

A missing Japanese army Black Hawk  helicopter carrying 10 crew members is believed to have crashed into the sea off a southern island after objects appearing to be aircraft parts were spotted in the area, an official said Thursday. The crash comes just days after nine U.S. soldiers were killed in a mid-air collision involving two Black Hawk helicopters near Fort Campbell, Kentucky.

The UH-60JA Black Hawk helicopter disappeared from radar on Thursday afternoon while on a reconnaissance mission north of Miyako island, the head of the Ground Self Defense Force, Yasunori Morishita, said at a news conference.

Debris believed to be aircraft parts was spotted in the area, about 1,120 miles southwest of Tokyo, he said.

The government is aggressively building up its defense capability in southwestern Japan in response to China's increasingly assertive military activity in the region, including Taiwan.

Kyodo News said Japanese coast guard ships also found traces of oil that may be related to the missing helicopter, but officials declined to confirm the report.

Morishita said the helicopter was stationed at a key regional army base in Kumamoto prefecture on the southern main island of Kyushu, and one of its 10 crew members is the division commander, Yuichi Sakamoto.

Morishita said the helicopter disappeared from radar earlier than previously thought.

NHK public television earlier said the helicopter disappeared from radar about an hour after it departed from Miyako island and about half an hour before its scheduled return.

Prime Minister Fumio Kishida said the Defense Ministry is investigating.

The crash came as the country works to significantly bolster its defenses in response to China's increasingly assertive military activity in the regional seas, where tension is also rising around Taiwan.

American-made Black Hawks are flown by a number of militaries around the world. Last month, the U.S. Army said nine soldiers were killed in a mid-air collision involving two Black Hawks near Fort Campbell, Kentucky, during a routine training mission.
