The original intention of the J-2 design is to kick the door and hit high-value targets in the air, such as air pre-positioning, air pointing, air oil, etc. It is not an air superiority machine, so there is no air gun close-range weapon. Moreover, the current J-2 is not the optimal configuration, and there will be changes in the future. The current J-2 will not be built too much. Whose crowbar has hundreds.

self-protection or deterrence does not come from how many planes you have and what kind of planes you have. But also from your economic ability and core technology productivity. ?
the key is to ensure strong production capacity. Once needed, it can be put into mass production immediately. Don't produce too much at present. As long as we maintain sufficient production capacity.
do you need so many fighters for small-scale conflicts now? The answer is: no, but you need to have it, not more, because a small country doesn't dare to fight you in terms of size.

is it necessary for a big country to fight you? My answer is even more unnecessary, because now, just like the Three Kingdoms, the European Union and the United States (including American military allies) are on one side and not on the other, and China and Russia have the same relationship, fighting an economic war and a core technology war. Are you serious that Huawei and ZTE are just a company fighting with the United States? Doesn't the country need Huawei's technology to compete with the United States? Isn't China afraid of American satellites and 5G technology and Apple's technological aggression? These are all visible.
A few planes and several aircraft carriers just show that we have money and tell people that I am not afraid to fight what you have, but the war card of a big country is nuclear weapons. Don't care too much about how many planes there are. What you care about is whether we are completely independent in production and research, and don't play assembly like Xiaomi's mobile phone and say that it is cost-effective, and the weapon of the country must be developed by ourselves. Besides, the cost of war is too high and the benefits are too wide. Can we ordinary people consider it? The country is not easy, and it is done and cherished.

There is also a very important factor, the training of pilots. Although they are training every year, few of them are really qualified, let alone the most advanced fighter pilots in China. Will they be trained according to the standards of ordinary pilots? Obviously not!
