SEOUL, Oct 31 (Reuters) - The United States and South Korea began one of their largest combined military air drills on Monday, with hundreds of warplanes from both sides staging mock attacks 24 hours a day for the better part of a week.
In protest of recent drills, North Korea has launched missiles, conducted air drills, and fired artillery into the sea.
Vigilant Storm will include variants of the F-35 stealth fighter from both the United States and South Korea, among other aircraft.
"(South Korea) and U.S. Air Forces will work together with the joint services to perform major air missions such as close air support, defensive counter air, and emergency air operations 24 hours a day during the training period," the U.S. Air Force said.
On Friday South Korean troops finished the 12-day Hoguk 22 field exercises, which featured mock amphibious landings and river crossings, including some drills with U.S. forces.
