According to Yonhap news agency, Seoul, August 19, the U.S. Pacific Air Force Command released a message on the 19th that four B-1B strategic bombers and two B-2 stealth bombers took off from the United States mainland and the base in Guam on August 17, flying over the Korean Strait and near Japan. According to the report, it is rare for six US bombers to appear in the coastal waters of the Korean Peninsula at the same time at the start of the joint military exercise between South Korea and the United States. Four B-1B bombers took off from days Air Force Base in Texas and Anderson Air Force Base in Guam. The B-2 stealth bomber took off from the recently deployed U.S. naval base on digogassia island in the Indian Ocean and flew all the way to the coast of Japan. < / P > < p > two B-1B bombers taking off from days Air Force Base conducted joint exercises with Japanese air defense force f-15j fighters. At that time, four f-15c and F-35B stealth fighters attached to Kadena base in Okinawa, as well as the F / A-18E Super Hornet deployed on the aircraft carrier “Ronald Reagan”, also participated in the exercise. The U.S. Air Force said the mission demonstrated the ability of the U.S. military to order lethal strikes to commanders of combat commands around the world anytime, anywhere. Kenneth welsbach, commander of the U.S. Pacific Air Force, said in this regard that the US military has the ability to carry out joint operations with allies at the time and place we choose. This “multi task work” highlights the ability of the US military to rapidly deploy troops to ensure the freedom and openness of the Indo Pacific region. According to the report, some military experts believe that the flight mission reflects the will of Robert Abrams, commander of the South Korea US joint command, that the Korean US joint show launched in Japan should focus on verifying the joint defense situation. Abrams has always advocated that the focus of the joint performance of command posts conducted by South Korea and the United States in the second half of the year should be to maintain and verify the joint defense situation. On the contrary, the South Korean military believes that evaluating the full operational capability (FOC) of the future joint forces command is the key. The South Korean and US military finally decided to focus on the evaluation of the combat capability of the South Korea US joint army command, rather than the full use capability.
