United States resumed F-16 fighter operations in Japan despite ministry request

Amid persistent security concerns, the U.S. military continues to operate F-16 fighter jets based out of its Misawa Air Base in Aomori Prefecture shortly after a dangerous incident in the region.

On November 30, the F-16 jet assigned to the Misawa base dropped two fuel tanks before making an emergency landing at Aomori airport. One of the tanks was found near a local municipal office and the other in a mountainous area.

The US military resumed piloting F-16 fighters after the incident without revealing its direct cause or details of measures taken to prevent it from happening again. The fighters fly to Hokkaido, the Tokyo metropolitan area and Kyushu.

“According to an explanation from the United States, the pilot during a test flight deemed it impossible to continue flying because there was a warning that the engine oil pressure was continuing to drop,” Defense Minister Nobuo Kishi said at a press conference on Tuesday.

The United States said there was “a time constraint and imminent danger,” Kishi added.

Kishi also said the US military will set up an accident investigation committee. “We will await the results of the investigation,” he said.

Each of the dropped tanks was 4.5 meters long, 1 meter in diameter and weighed 215 kilograms, according to the Defense Ministry.

On December 1, the ministry asked Lt. Gen. Ricky Rupp, commander of US forces in Japan, to suspend flight operations of the F-16 jets until the safety of the fighters was confirmed. However, the US military unilaterally resumed F-16 operations the next day.

Rupp visited the ministry on Friday, when Kishi expressed regret over the incident. Rupp explained that flight operations resumed after safety checks were carried out on all F-16 jets.
