Five Chinese warships, the PLAN’s delegation to RIMPAC 2016, rendezvoused with two USN destroyers, the USS Stockdale and USS Lawrence near the Daito Islands (just southeast of Okinawa), on June 18, 2016. The seven ship taskforce, with the USS Stockdale as flagship, will arrive at Hawaii for RIMPAC 2016 on June 29. Three other groups, one from Singapore, and the other two from San Diego, are also sailing to Hawaii (an amphibious component also takes place in Southern California). Hosted biennially by the US, RIMPAC is the world’s largest regular multi-national exercise, incorporating dozens of countries each time (China’s first participation was in the previous RIMPAC, 2014). Running from June 30 to August 4, RIMPAC 2016 will involve twenty seven nations, fifty ships (including five submarines) over two hundred aircraft and 25,000 personnel. Noticeably, this is the first RIMPAC that will involve a submarine rescue exercise (of which China will play a key part in). This year, the Chinese task force consists of the Type 052C class “153” Xian guided missile destroyer, the Type 054A “546” Hengshui guided missile frigate, Type 903A ” 966″ Gaoyouhu replenishment ship, the Peace Ark hospital ship and Type 926 submarine tender/rescue ship “867” Changdao. Additionally, there is one special forces team, one naval diving team and three helicopters with the Chinese contingent. Only the American and Canadian contingents will be larger. The task force left Zhoushan, Zhejiang on June 15, 2016. China Military Online reported that the seven ship taskforce will conduct a series of exercises during the 11 day voyage, including communications, at sea resupply, aerial photography and live fire artillery exercises. This will be presursor to closer naval cooperation; the Changdao will be one of the stars of RIMPAC’s inaugural underwater rescue component.
