If the Air Forces of China and the United States are at war in the future, it will inevitably be a coordinated operation of multiple services, because this depends on the nature of modern warfare. For example, fighter jets of the U.S. Navy took off from U.S. aircraft carriers and joined the war. So there is a factor that can lay the foundation for the victory of the war, that is, who seized the air supremacy?

What is air supremacy? What does it take to be successful?
The concept of air supremacy was born with the application of aircraft to the military, and was first proposed by a British major in 1893.
The outbreak of the First World War brought air supremacy to the stage of actual combat for the first time, and how to seize air supremacy also became the key to the engagement between the two armies. During the Second World War, the seizure of air supremacy ran through the entire war, and the importance of air supremacy was once again confirmed. With the development of high-tech technology and the diversity of military weapons, different ways of seizing air supremacy have also evolved.
In fact, the seizure of air supremacy was first a concept in air combat, because at that time, as long as enough fighters were annihilated, it was considered a successful air supremacy seizure. Later, the diversification of the country's military development gave the air superiority a different concept, that is, to ensure that enemy fighters could not fly while ensuring that they could not fly. That is to say, do not let the enemy have the ability to attack, but have the ability to attack.
For modern warfare, the connotation of the term air supremacy has changed again. That is, one side has an overwhelming advantage in air attack and defense, can complete air combat tasks, can also suppress and destroy the firepower of the other side, and can control its own losses within the bearable range.
Theoretically, a successful air supremacy would require two tasks.
The first task is to strike and destroy the enemy's airfields and other aviation facilities by fighter jets, cruise missiles and other weapons, and to destroy the enemy's logistics positions on the ground.
The second task is to strike at enemy air fighter jets with surface-to-air missiles, electronic warfare and other weapons.
If China and the United States go to war, how can we take the lead in seizing air supremacy?
The first is to directly destroy the airfield or aircraft carrier platform in the rear of the US military, and this is the fastest and most effective way to seize air supremacy.
If we blow up the US air bases in the Asia-Pacific region before the US fighters can take off, then the US military will not engage us in the air for a short period of time. This effect should be said to be the most ideal, but there is a problem of robbing time and timing.
If, after the Takeoff of the American fighters, we blow up their rear bases, then these fighters that have already taken off will not be able to guarantee long-term air combat. Because after a period of time, the fighter must return to the airfield for ammunition replenishment. If we sink a U.S. aircraft carrier, it will be the same effect.
Therefore, this method is equivalent to "catching the thief before capturing the king", directly cutting off the back road of the US army, but this also has a high level of requirements for the military strength of our PLA.
At present, the Chinese People's Liberation Army has completely such a strike capability. We have "Guam Express", "Okinawa Express", and "Dongfeng 21d", "Dongfeng 26" anti-ship ballistic missiles. As a result, we are perfectly capable of launching missiles on our doorstep to blow up air bases and maritime carrier platforms in the rear of the U.S. military.
However, there are also cases where this most effective approach does not work. If the U.S. military were not moving an aircraft carrier, but an aircraft carrier formation, our strike might only sink one of them.
Once this situation occurs, the emergency repair capability of the US rear base is very strong, enough to use the time difference to resist one or two waves of our "Dongfeng Express". Therefore, if "Dongfeng Express" wants to play a suppressive blow effect, it must expand the number of Dongfeng Express.
The second is to use stealth fighters for stealthy close-range penetration. For example, stealth fighters such as the J-20 strike at large airborne early warning aircraft or electronic jamming aircraft of the US military at close range during combat.
Because the US military operations are systematized, once the US military loses this large air warning and command capability, then the US military's system combat capability will decline rapidly.
Third, the use of anti-aircraft missiles on the ground to destroy the enemy's early warning aircraft and electrical interference.
In 1998, our Zhuhai Air Show showed an anti-radiation anti-aircraft missile called the ft2000. That is to say, this missile uses a passive radar seeker to carry out long-range strike radar radiation aircraft, specifically to deal with the EARLY WARNING aircraft and electronic jamming aircraft of the US military.
After being exhibited at that time, there was a nickname of "AWACS Killer". If China and the United States are at war, we can use it to knock out the information nodes of the US military, and the early warning aircraft and electronic jammers will have no power to fight back. Our warplanes have a clear advantage over the US warplanes.
In summary, if war breaks out in the future, air supremacy must be a very important point. At the same time, the seizure of air supremacy is not only limited to the "you live and die" competition between fighters, but also the assistance of various other means, including how to grasp the opportunity and how to coordinate command and coordination.
