Recently, a fighter jet group under the PLA air force successfully completed a 10-hour continuous flight, setting a new record of the single flight duration of PLA fighters. The mission area of this troop covers the waters of the South China Sea. It will take 10 hours to conduct a patrol and alert lap flight to the islands in the South China Sea. Therefore, this new flight record has an important strategic significance for the full-coverage patrol and alert in this area.
