The Joint Chiefs of Staff says South Korea took part in a multinational antipiracy naval exercise involving U.S., Japanese and British forces held in the Gulf of Aden.

The Cheonghae Unit's 44-hundred-ton destroyer Choe Yeong took part in the Thursday drill in waters some 160 kilometers east of Djibouti. 

P-3 maritime patrol aircraft, helicopters, rigid-inflatable boats and special naval forces were also mobilized. They trained for vessel interdiction and search, takeoff and landing of helicopters, and other maneuvers required in antipiracy operations.

Japanese Rear Admiral Tatsuya Fukuda was in charge of the command and control of the four-nation exercise. Fukuda is the current commander of Combined Task Force-151, which is a joint naval task force dedicated to eradicating piracy and armed robbery in the Gulf of Aden.
