B-52 bombers from Guam have trained with Air Self-Defense Force and Okinawa-based U.S. fighter jets in the Western Pacific, just days after China sent a total of six bombers and other aircraft through a key entryway into the Pacific for their own military exercises.

"Two B-52H Stratofortress bombers took off from Andersen Air Force Base, Guam, and conducted integrated training with Koku-Jieitai (Japan Air-Self Defense Force) fighters and 18th Wing F-15s from Kadena Air Base, Japan, in the vicinity of Western Japan" on Thursday, U.S. Air Force spokeswoman Monica Urias told The Japan Times.

The mission made for a busy week in the area, with the Chinese Air Force dispatching a total of six H-6G and H-6K bombers, as well as electronic warfare and surveillance aircraft and fighter jets, through the Miyako Strait, international airspace between the Japanese islands of Okinawa and Miyako in the East China Sea, on Monday and March 30.
