Is the speed of the J 10 high subsonic?

First of all, it is necessary to clarify the trend of aircraft speed.

After World War II, full-fledged first-generation jets (such as the MiG-15 and F-86) appeared, and the aircraft at that time could only fly in the range close to the speed of sound due to design limitations. Full-fledged supersonic technology was officially mastered by mankind, starting with second-generation aircraft, such as the MiG-21 and F-4, when aircraft were characterized by high altitudes and high speeds. Later, in the Vietnam War, the advanced F-4 was actually beaten down by the old MiG-17, and the United States began to reflect and believe that the main speed range of air combat is high subsonic speed (that is, subsonic, but close to the speed of sound, roughly 900-1000km h), so in the third generation aircraft (such as Su-27 and F-15) began to pay attention to high subsonic maneuverability, of course, the aircraft at this time is also very casual to surpass the speed of sound.

In the case of fourth-generation aircraft (such as the F-22 and T-50), in order to emphasize the rapid arrival in the war zone, the aircraft is required to have the ability to fly at supersonic speed without turning on the afterburner (the afterburner in the engine, and ordinary aircraft can only get high thrust to maintain supersonic flight by opening the afterburner, and at the same time pay the price of high fuel consumption), but the main air combat speed range is still high subsonic, and it can also be very arbitrary supersonic speed.

As for the J-10, it belongs to the third generation aircraft, and does not have the ability of the fourth-generation aircraft to fly at supersonic speed (also called supersonic cruise), and the main air combat speed range is also high subsonic, but the maximum speed can be above times the speed of sound).

In addition, the above speed does not involve reconnaissance aircraft, verification aircraft, etc., because the SR-71 and MiG-25 can exceed 3 times the speed of sound, the X-15 has long crossed 5 times the speed of sound, and the X-43A has also crossed 10 times the speed of sound.

The speed of the J-10 fighter is high subsonic, and the high subsonic speed is about the highest speed of sound. And the cruising speed of the J-10 fighter is around times the speed of sound. The J-10 fighter is not yet capable of supersonic cruise, although the maximum speed can reach twice the speed of sound.

There are still very few fighters capable of cruising at supersonic speeds.

The J-10 is a third-and-a-half-generation fighter. As the most advanced domestic fighter in China at this stage, the maximum speed at high altitude: Mach, and the maximum speed at low altitude: Mach (1473 km h).

The current fighters are all supersonic fighters, and if China is engaged in a subsonic battle, it will be too backward.

Cruising is at this speed, and the top speed should be around m2. Although resistance under a combat load is completely impossible, at least supersonic is fine.

No, it's super-fast, super-sonic speed, very fast.

The fastest is supersonic.

Its performance is as follows:

Maximum speed Mach 1 (low altitude).

Maximum speed 1250 km/h (low altitude).

The J-10 is a third-generation aircraft with over-bottom penetration
