The United States has sent a special military aircraft that "sniffs out" nuclear weapons to Okinawa in the wake of more expected missile tests in North Korea.
Stars and Stripes reports the Air Force WC-135 Constant Phoenix — nicknamed "The Nuke-Sniffer" for its ability to locate deadly explosives — landed arrived at Kadena Air Base last week.
The plane collects air samples and debris which can point to the presence of nuclear materials.
North Korea conducted two nuclear tests and test-fired nearly 30 missiles since last year, according to Stars and Stripes, the U.S. military’s independent news source.
And this weekend, it will celebrate the 105th birthday of Kim Il Sung, its late founder and grandfather of current leader Kim Jong Un.
The New York Times reports that Kim is expected to "use the occasion to either stage a nuclear weapons test or conduct a missile test, in direct defiance of the United States and its main patron, China."
