Cheonan
U.S. and Republic of Korea service members view the salvaged wreckage of ROK naval ship, Cheonan, at the ROK Navy 2nd Fleet Command at Pyeongtaek Navy Station, June 21, 2012. Forty-six Korean service members were killed, March 26, 2010, when a North Korean submarine sank the Cheonan with a torpedo. The detonation location was three meters to port from the center of the gas turbine room. The purpose of the tour is for ROK-US service members at Osan AB to acknowledge Korean security situations and strengthen the spirit of defending peace and liberty on the peninsula.
