SEOUL, Nov. 23, 2017 (Yonhap) — The United States is planning to send six F-22 Raptor stealth fighter jets to a joint air force exercise in South Korea next month in what is believed to be U.S. action to put maximum pressure on North Korea, military officials in South Korea have announced. “Six F-22 fighters from the U.S. Air Force are scheduled to join the joint South Korea-U.S. air force exercise Vigilant Ace from Dec. 4-8,” the officials said.

The fighters will fly to the Korean Peninsula from Kadena Air Base in Okinawa, Japan and stay at an air base in South Korea throughout the exercise. Up to four F-35A Lightning stealth fighters are also likely to join the deployment, they said.

The U.S. fleet will reportedly engage in enemy infiltration and precision strike drills with South Korean Air Force fighter jets during the exercise.

It would mark the first time the U.S. has deployed six Raptors to Korea at once and is sure to put pressure on North Korea with the overwhelming military force by the allies.

The Raptor, an air superiority fighter, is capable of flying to key enemy facilities and launching precision attacks under the radar. Its maximum speed is about Mach 2.5

The planned deployment comes as the U.S. steps up the deployment of strategic assets to South Korea in a show of force aimed at pressuring North Korea to the maximum level. Early this month, three U.S. nuclear-powered aircraft carriers were deployed to the East Sea after powerful American fighter jets flew near North Korea in the previous months.

South Korea and the U.S. are escalating pressure, both economic and military, on North Korea in efforts to bring the country back to the table to negotiate its illegal development of nuclear weapons.

The US Pacific Air Forces Office of Public Affairs emphasized the drills are an annual event named VIGILANT ACE 18. VIGILANT ACE is a regularly scheduled flying exercise.

It will involve 12,000 U.S. personnel who will participate along with the Republic of Korea Air Force. The realistic air combat exercise is designed to enhance interoperability between U.S. and Republic of Korea forces and increase the combat effectiveness of both nations.

U.S. Air Force, Marine Corps, and Navy personnel will train with air assets from the Republic of Korea, flying 230 aircraft at eight U.S. and ROK military installations. VIGILANT ACE is part of a continuous exercise program designed to enhance readiness and operational capability of U.S. and ROK forces.

Previously known as Beverly Bulldog, VIGILANT ACE 18 highlights the longstanding military partnership, commitment and enduring friendship between two nations. It is designed to ensure peace and security on the Korean Peninsula, and reaffirms the U.S. commitment to stability in the Northeast Asia region.
