Since both the army and the navy have their own air forces, which air force is so important?

Let's just say that the tasks that the Air Force is responsible for sound very high, that is, national air defense and strategic deterrence counterattack. Prior to this, the naval forces of countries with aircraft carriers were very strong, so the air force was weak or even no air force, and with the air force, its naval forces were relatively weak. Just like Germany and Britain from Europe, their air force is relatively strong, while the HNA troops are relatively weak or not, while Japan and the United States in the East have no air force, but their HNA troops are particularly strong. Both the United States and Japan established air forces after the war.

Du Hei, the world-famous founder of air force theory, once said in his famous book "Air superiority" that "the appearance of airplanes makes war no longer the responsibility of front-line soldiers, people behind the front line are not safe, and the production machines supporting the war in the rear will be the key targets of the enemy in future wars. The emergence of aircraft will make war no longer a matter of the army, but a matter of the country and the nation. " This sentence was later implemented by Britain and the United States in Germany and Japan respectively, that is, long-distance indiscriminate bombing of the enemy's production machines to support the war was a strategic bombing in the military.

However, HNA troops basically did not participate in seizing the air superiority in inland areas. In the early days, both Germany and Italy used the air force to carry out tactical bombing and strategic bombing, which made the air force's operational pressure greater and the allocation of operational resources more difficult, especially when conducting cross-service joint command. It makes the German Air Force not like a strategic bombing, but more like an army and aviation unit providing tactical support. Therefore, in order to conduct more professional command and resource allocation, the United States and other countries have established independent air force services after World War II. Up to now, the army aviation basically uses helicopters to carry out anti-tank and fire resources, while the air force is mainly responsible for the fixed-wing aircraft to seize the battlefield air superiority and carry out strategic bombing when necessary; Defense, mainly responsible for national air defense, including aircraft interception and tactical ground-to-air missile interception.
