Who can introduce the F 15 fighter with canard?

F22 also added duck wings. Duck wings can fly with their heads up, and the angle of attack is good. When attacking the ground, you can quickly pull up the nose and escape from the scene. Backflip is fast, not suitable for stall, and is beneficial to turn around and attack. Modern fighters have duck wings, and so do gusts and typhoons. F 15 is equipped with longitudinally adjustable canards, which are used for high-speed maneuvering, supersonic turning, ultra-low altitude supersonic dive attack and supersonic pull-up. You can also slide in space and attack without power.
