SOUTH CHINA SEA (March 8, 2009) Two Chinese trawlers stop directly in front of the military Sealift Command ocean surveillance ship USNS Impeccable (T-AGOS-23), forcing the ship to conduct an emergency "all stop" in order to avoid collision. The incident took place in international waters in the South China Sea about 75 miles south of Hainan Island. The trawlers came within 25 feet of Impeccable, as part of an apparent coordinated effort to harass the unarmed ocean surveillance ship. (U.S. Navy photo.)
