In modern air combat, fifth-generation stealth fighters such as the J-20 rely more on long-range precision guidance** for preemptive strikes. For them, dogfighting, that is, close air combat within line of sight, does not seem to be the preferred tactic. However, if the system fails, or if a situation arises with the depletion of missiles, then the situation in air combat can become complicated. So what should the J-20, which does not have a cannon, do in such a situation?
In fact, the fact that the J-20 does not have a cannon does not mean that it is powerless in close-range air combat. First of all, the J-20 can use its excellent electronic warfare capabilities to jam enemy aircraft to achieve self-protection and even counterattack. This includes the use of electronic jamming to obfuscate the enemy's guidance system and deprive the enemy of the ability to attack itself.
Secondly, the J-20 can also try to trade maneuverability for tactical superiority. The J-20 has shown great performance in terms of speed, ceiling, and maneuverability, which makes it have a high chance of survival in close air combat. Even without missiles and cannons, the J-20 can still try to create opportunities to escape from the pursuit of enemy aircraft and even turn to the offensive by means of maneuvering and jamming.
In addition, the J-20 can also choose to use tactical evacuation. In addition to its powerful electronic warfare capabilities and advanced mobility, the J-20 is also equipped with a powerful power system, and its cruising speed is extremely high, allowing it to quickly flee when leaving the battlefield to protect itself.
Finally, it should be noted that neither the J-20 nor any other fighter can win in any situation. The complexity and diversity of modern air combat necessitate a variety of capabilities to cope with different battlefield environments. The J-20 fighter undoubtedly has such capabilities, but it also faces challenges. Therefore, the designers and users of the J-20 will always pay attention to and study how to improve the survival chances of the J-20 in extreme situations.
