South Korea news outlet Chosun reported recently that the U.S. has been considering using this armada to test North Korea like never before, by sailing the aircraft carrier north of the Northern Limit Line, the de facto maritime border of North Korea.
The South Korean navy was quoted by local media outlets as saying the joint exercise with the USA navy would be staged from next Monday to Friday in the eastern and western waters of South Korea.
The drill is slated for October 16 and will include the USS Ronald Reagan aircraft carrier as well as South Korean vessels.
The drill, called Maritime Counter Special Operations Exercise, is aimed at defending the infiltration of enemy special forces, according to the navy.
The exercise will provide a visible and coordinated engagement for the U.S. - ROK alliance.
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 Michigan, a nuclear-powered attack submarine, carries with it some 150 Tomahawk cruise missiles that experts told Business Insider could prove incredibly useful in a strike on North Korea's nuclear infrastructure.
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 USA and the Republic of Korea".
Two U.S. B-1B Lancer bombers flew over the Korean peninsula in a show of force on Tuesday night, conducting air-to-surface missile-firing drills over the Sea of Japan (known in Korea as the East Sea) and the Yellow Sea.
