It was the second port call of the USA submarine to the South Korean port city.
For the exercise, the South Korean military will also mobilize P-3 anti-submarine aircraft, F-15K, FA-18, A-10 fighter jets and Lynx, AW-159, UH-60, MH-60R helicopters.
Vessels from the United States Navy and the Republic of Korea (ROK) Navy are scheduled to participate in the Maritime Counter Special Operations exercise (MCSOFEX) Oct. 17-20, in the East and West Seas to promote communications, interoperability, and partnership in the 7th Fleet area of operations. In April, South Korean media reported that Navy SEALs aboard the MI had trained with a local force to decapitate North Korea's Kim Jong Un regime.
The Los Angeles-class attack submarine the USS Tucson (SSN 770) pulled into the U.S. Fleet Activities Chinhae base on October 7 "as part of its deployment to the Indo-Asia-Pacific region", the U.S. Navy said on Tuesday. The super-carrier is accompanied by Aegis destroyers, guided missile cruisers, combat support ships and a nuclear-powered submarine.
Cmdr. Chad Hardt, commanding officer of the Tucson, said the deployment gives the Navy an "opportunity to strengthen the outstanding relationship that exists between the US and the Republic of Korea".
