A Japan-based combat-ready Air Force wing showed off its aircraft Wednesday in a clear warning to North Korea.

Fox News reported the 18th Wing conducted a surprise military exercise at Kadena Air Base in Japan as North Korea is rumored to be nearing a sixth nuclear weapons test.

A group of HH-60 Pave Hawks, F-15 Eagles, E-3 Sentries and KC-135 Stratotankers all took part in the exercise, the report said. Photos from the no-notice event showed jets lined up down the entirety of a runway on the base.

Such exercises are known as an "elephant walk," featuring planes taxiing in tight formation before takeoff.

China has warned North Korea's adversaries not to make any rash actions because "military force cannot resolve the issue," according to Chinese Foreign Minister Wang Yi.

North Korea has conducted two nuclear tests and about two dozen missile tests in the last year.

The show of force is in addition to the recent deployment of the Carl Vinson Carrier Strike Group to the region. The group of ships, comprising an aircraft carrier, two destroyers and a cruiser, had been scheduled to visit Australia before it was rerouted this weekend.

President Trump this week urged Chinese President Xi Jinping to solve the problem of an agressive North Korea, or else, he said, "we will solve the problem without them!"
