SEOUL, July 26 (Xinhua) -- South Korea and the United States continued with their joint naval exercise Monday in waters off the east coast of the Korean peninsula, a day after the allies begun a four-day naval exercise in the face of growing tensions in the region.
The second day of the drills focused on anti-submarine exercises involving the U.S. aircraft carrier USS George Washington, aimed at detecting and defeating submarines intruding into the seas east of the peninsula.
The exercise consisted of simulated attacks on enemy submarines and live-fire drills by a squadron of fighter jets off the east coast, Seoul's Yonhap News Agency quoted Lee Bung-woo, a spokesman for the country's Joint Chiefs of Staff (JCS) as saying.
As part of Monday's drills, four F-22 Raptors, the world's most advanced powerful fighter jet flew over South Korea for the first time, according Yonhap.
On Tuesday, the two countries will fire naval guns and artillery at an abandoned submarine disguised as an enemy submarine, Lee was quoted as saying.
The drills will also involve firing underwater torpedoes, solidifying defense agaist sea and air intusions and air-to-air refueling, Lee added.
