One-third of the fuel is used to go to the battlefield, one-third of the fuel is used to return, one-third of the fuel is used for air combat, which means that under ideal conditions, the combat radius can only go one-third. First, a fighter plane that can fly 1,000 km on a full fuel tank has a combat radius of just over 300 km. Yan'an is 1,200 km from Ulaanbaatar. These planes fly here to spread leaflets. Isn't their flight range more than 3,000 km! ?
