According to the South Korean Central Daily in May 2nd, in May 1st, many government sources said the US Air Forces F-22 Raptor had recently set out from the United States and landed at Gwangju Airport in South Korea. A source said, these stealth fighters are to participate in the South Korea United Air military exercise - MaxThunder, held in South Korea from the 11 day. There are about 8 F-22 Raptor fighters suspended at Gwangju Airport, the report said. On the same day, a number of photos of the F-22 Raptor flying scenes captured near the Kwangju wide area were also posted on the Internet. Since 2009, the super thunderstorm air combat exercise has been held annually in the first half of the year, which is close to actual combat air combat training. In last years exercises, the Korean Air Forces F-15K and the US Air Forces K-16 and more than 100 fighters participated. This is the first time that the F-22 Raptor fighter took part in the super thunder military exercise. The report said that the F-22 Raptor was sent to Korea in December last year to participate in the joint air military training, called the VigilantACE, and the output of the F-22 Raptor (187), which is also a very valuable strategic resource for the US air force. It is therefore believed that the emergence of the F-22 Raptor or the upcoming US and DPRK summit is related to the US President Trump or the plan to maximize pressure on the DPRK. At the end of last month, after a meeting between the Korean President and the Korean supreme leader Kim Jeong-eun at the free house on the Korean side of the Panmunjom, the talks between the US and the north and the DPRK were the subject of much concern. According to previous reports from World Wide Web, Trump suggested that the summit meeting between the US and the DPRK should be held in the demilitarized zone of Panmunjom. He also said that at present, the parties are arranging, and it is expected that the location and date will be announced in the next few days. According to the report, the Korean and Korean DPRK heads of the United States and the DPRK are even more attracted by the decision of the Korean Peninsula to achieve the goal of denuclearization of the Korean Peninsula.
