U.S. intelligence-gathering aircraft have been taking off from an American air base in southern Japan, a day after North Korea said it tested a hydrogen bomb.
At least three planes departed Thursday from Kadena Air Base on the Japanese island of Okinawa.
It wasn’t clear what they were doing, but they could be involved in trying to determine what kind of nuclear device North Korea detonated.
One of the aircraft seen departing, the RC-135S, collects optical and electronic data from ballistic targets. It is used for arms treaty compliance verification and U.S. strategic and missile defense development.
White House spokesman Josh Earnest told reporters in Washington on Wednesday that “the United States will be collecting additional evidence” and working closely with other countries in the region to learn more about the North Korean test.
