S.Korea-U.S anti-submarine drill conducted night of Cheonan sinking

United States Forces Korea (USFK) officially confirmed Sunday that 20 minutes prior to the sinking of the Cheonan, South Korea and the U.S. had conducted an anti-submarine drill some 139 kilometers away in which a South Korean submarine played the role of a target. This marked the first time since the sinking that U.S. officials have concretely discussed what specifically goes on during joint South Korea-U.S. drills.

Quoting U.S. military officials, the Associated Press (AP) reported Saturday (local time) that prior to the sinking of the Cheonan, two US destroyers and other ships practiced tracking while a South Korean submarine played the role of enemy.

The AP reported Western experts stated there are still questions about what happened that day near Baengnyeong Island. In particular, one official who asked to remain anonymous, since he was not authorized to discuss the issue, said the sinking of the Cheonan “may not have been an intentional attack at all, but the act of a rogue commander, an accident or an exercise gone wrong.”

Won also said that since the drill was conducted 170 kilometers from the site of the Cheonan sinking, it had nothing to do with incident. As for why the location point of the drill differed in the South Korean and US explanations, a military expert said the difference could be because mobile maritime drills on the sea take place over dozens of kilometers.
