On the question of the fourth generation heavy destroyer, the fourth generation fighter

4S performance of fourth-generation aircraft: super-maneuverability, supersonic cruise, over-the-horizon air combat and stealth performance.

First of all, maneuverability, we do not know the model and performance of the engine, only that it is twin-engine. However, looking at the aircraft equipped with a movable delta wing, there is a large delta wing shape between them, and the tail is also changeable, presumably from the design of maneuverability, so the maneuverability should not be bad.

The second is supersonic cruise, which still depends on the engine, and there is no way to talk about it.

Third, over-the-horizon air combat. First of all, a powerful fire control radar is needed, which we also do not see and do not understand. The second is missiles, China's over-the-horizon air-to-air missiles in service have made great progress, and they should be able to meet the needs of fighters when they are in service, and they can also be imported.

The fourth stealth, the stealth design can also be seen from the shape of the appearance, which is an obvious feature of the fourth-generation aircraft. As for the materials, we can't see it, and we only hope that the relevant materials in our country have been developed accordingly.

So on the whole, we don't know much from the appearance, the fighter is still relatively large, and the network says that the bomb load may be very large, so I only hope that China's fourth-generation aircraft can be very strong.

This is my superficial opinion, but this also requires the most basic conditions, that is, this network ** is true.

J-22, J-20, these two fourth-generation aircraft. The J-22 belongs to the aircraft carrier that can be used on aircraft carriers, and it was developed by Shen Fei. The J-20 that has become a flight should belong to the fighter aircraft that imitates Europe and the United States.

Believe in his existence and look forward to his strength!

The most pertinent answer is the verification machine, which is not yet available in many technologies.

1. It indicates that the pace of modernization of China's Air Force is accelerating, the research and development capability has been greatly improved, and the determination and confidence are also very high;

2. It shows that China's air force is already taking a path of independent development, and it is aiming at the development trend of the world's air force and the needs of future actual combat.

3. The next 10 years will be a good time for China's air force to greatly improve its combat effectiveness, and it is expected that the gap with the world's first-class air force will be significantly narrowed. After 2020, China's offensive and defensive capabilities will have a greater impact on the situation in the Asia-Pacific region and even the world, and will play a positive and key role in maintaining Asia-Pacific stability, peripheral security and world peace.

At present, the more advanced fourth-generation fighters include the F-22 and F-35 of the United States, and the Su-47 of Russia. The main features are outstanding stealth performance, supersonic cruise capability, unconventional maneuverability and agility, short take-off and landing capability (or all-environment combat capability), referred to as 4S. It adopts a turbofan engine with a thrust-to-weight ratio of 10 levels, a phased array fire control radar, stealth technology and thrust vector technology, etc., with "launch and forget" air-to-air missiles as the main one.

In comparison, the American fighters pay more attention to stealth and fire control systems, while the Russian fourth-generation fighters are similar to the original first, second, and third-generation aircraft, mainly in terms of bomb load, close-range air combat, maneuverability, and maintenance convenience are better than those of the Americans. The current military strength is not measured by quantity, but by quality, and in general, each has its own strengths and weaknesses!

The following is the data address of the most advanced fighters of the United States and Russia, you can compare.
