The increased cooperation comes under a charter signed earlier this month in Korea by senior leaders of both navies.
The charter covers the exchange knowledge and development of training scenarios and establishment of special working groups, according to U.S. Naval Forces Korea.
"Anti-submarine warfare is one of the most challenging yet critical tasks that our navies exercise," said Vice Adm. Robert L. Thomas, commander, U.S. 7th Fleet. "It takes a strong combined body of talented people and a cooperative plan to work together to achieve our full potential in ASW capabilities."
U.S. and South Korean ships conduct about 20 joint exercises a year around the Korean peninsula and the charter "paves the way for a stronger partnership between our navies ...," said Cmdr. Kim Beom Woo of the Republic of Korea Fleet headquarters.
