North Korea, Seoul's defense ministry said Thursday.The drill from February 20-24 will involve a number of submarines and warships from both countries, a ministry front man told Agence La Belle France Presse without elaborating.
JoongAng Ilbo newspaper said the drill would involve some 20 craft including two Aegis ships from the U.S. and one from South Korea, as well as Lynx helicopters and P3-C anti-submarine surveillance aircraft.
Citing an unidentified Seoul military official, it said the exercise would be the largest anti-submarine joint drill carried out by the allies.
The two countries staged a joint anti-submarine drill in September 2010, months after Seoul accused Pyongyang of torpedoing a warship with the loss of 46 lives in the Yellow Sea in March 2010.
The North denied it sank the ship. But in November that year it shelled a border island, killing four South Koreans.
The upcoming drill, to precede two other major joint exercises, comes at a sensitive time in the North which is undergoing a power transition.
