By Cmdr. Divers from the United States and Indonesian Navies began a six-day diving operation July 21 to survey a wreck in Surabaya harbor as part of joint naval engagement activities (NEA) between the two nations. A joint diving team will conduct survey dives to identify the sunken vessel and determine potential salvage hazards such as fuel, explosives and dangerous cargo. Once the survey is complete, the diving teams will develop an underwater mechanical demolition plan to raise the vessel and remove it from the harbor.
