The F-4 fighter jet, code-named Phantom II, is a two-seat, twin-engine all-weather long-range supersonic air defense interceptor or fighter-bomber of the United States. As a typical representative of the second-generation fighter jets, it has relatively balanced performance in all aspects. Not only is it good in air combat and dogfighting, but its ground attack capability is also not weak. The disadvantages are that the turning radius is too large, the maneuverability at high angles of attack is poor, the performance at high altitudes and ultra-low altitudes is slightly inferior, and the requirements for the runway during takeoff and landing are relatively high.
