WASHINGTON – The U.S. Navy has deployed sophisticated surveillance aircraft to Japan, officials said Monday, amid rising tensions over China’s territorial claims in the region.
Two P-8A Poseidon patrol jets departed Jacksonville, Florida, on Friday and arrived later at Kadena Air Base in Okinawa, in a move that was planned before Beijing declared an air defense identification zone (ADIZ) last month covering disputed islands in the East China Sea, a navy official said.
“This was scheduled for a long time,” said the official, who spoke on condition of anonymity. “It’s a rotational deployment.”
Four more Poseidon aircraft are due to deploy to Okinawa later this month, the official said.
The assignment to Japan marks the first mission for the new plane, which is replacing the propeller-driven P-3 Orion aircraft that dates back to the 1960s.
The P-8A planes, converted Boeing 737s equipped with advanced radar and anti-ship missiles, are designed to hunt submarines and track other vessels at sea.
On Nov. 23, China announced an expanded ADIZ and said aircraft would have to submit flight plans before entering the area, home to the Japanese-administered Senkaku Islands, which are also claimed by China and Taiwan.
Japan, South Korea, Taiwan and the United States have each sent planes into the zone without informing the Chinese, signaling their refusal to recognize Beijing’s declaration.
After sending in two B-52 bombers last week, the U.S. military has kept up “routine” military flights in the area, receiving no hostile response from China, Pentagon spokesman Col. Steven Warren told reporters Monday.
“The Chinese reaction to our operations has been normal,” Warren said.
“We haven’t changed our operational tempo,” he added.
The deployment of the P-8 aircraft came as U.S. Vice President Joe Biden set out Sunday on a trip to Asia that will include a stop in Beijing, where he will discuss the spike in regional tensions.
Senior U.S. officials said Biden would convey Washington’s “concerns” about China’s ADIZ and seek clarity regarding its intentions.
While military flights have gone ahead as planned, the U.S. State Department has advised American commercial airlines to observe China’s demand for advance notice when entering the zone.
China and Japan have been locked in a mounting territorial argument over the Senkakus, which are known as Diaoyu in Chinese.
Although taking no position on the sovereignty dispute, Washington says it would uphold its defense treaty with Japan in the event of a conflict.
