A Japanese surveillance plane flew over disputed waters in the South China Sea on Tuesday, as part of joint drills with the Philippines. As The Diplomat reported previously, the Philippines is holding separate drills with the United States and Japan this week, with both exercises held near the South China Sea. The Japan-Philippine drill, only the second ever between the two countries, simulated maritime search and rescue operations, part of the drill’s larger focus on humanitarian assistance and disaster relief.
As part of the drill, a Japanese Maritime Self Defense Force (MSDF) P3-C Orion surveillance plane flew past Reed Bank, an area claimed by both China and the Philippines. The Japanese plane carried three Philippine crew members on board as guests, and was accompanied by a Philippine patrol aircraft, Reuters reported.
Philippine Marine Colonel Jonas Lumawag, describing the drill, told reporters, “We practiced search and rescue patterns, which are essential in any humanitarian assistance and disaster response operations.” According to Yomiuri Shimbun, the drill involved a mock search for a shipwrecked vessel. However, Yomiuri also noted that the Philippine officers on board were “apparently greatly impressed by the P-3C’s excellent ability to detect submarines” – exactly the capability that makes China most nervous about U.S. P-3 patrols. In the post-drill press conference, Lumawag said that the Philippines is eager to learn from Japanese experience operating such surveillance planes.
Still, the Philippines was quick to note that the drills (both with Japan and with the United States) are not aimed at any specific country. “The Philippines has had these exercises before with our strategic partners. It should not be taken as an affront to any other and is an expression of cooperation and learning from all those involved,” Deputy Presidential Spokesperson Abigail Valte told The Philippine Star. A Navy spokesperson agreed, saying, “We are doing this for interoperability” – not to send a message about the maritime disputes.
