When will the J 7 fighter be discharged

It will not be completely decommissioned for the time being.

Because the current production of J-10 and J-11 is not enough, it cannot completely replace J-7.

At present, the main engine production of the new fighter is too small, and the engine installed on the J-10 seems to be too good.

But the production is too small to meet the needs.

When the output of new engines goes up, the J-7 will be able to be laid off.

It is estimated that the new J-7 will not be retired until the fourth-generation aircraft is equipped on a large scale, and most of the old models will be gradually retired from active service.

It's time to be a target.

The next target aircraft in the United States should be the F-16....

Well, let's talk about the pros. The MiG-21 is still quite small, and the shock cone on the front, although the RCS is not small, at least hides part of the engine. In this way, the J-7 is not equipped with a pulse-Doppler fire control radar, and the weakness of the lack of radar guidance ** can at least partially be compensated.

The 226 radar is capable of ranging at close range, providing distance for infrared missiles.

In terms of maneuverability, the J-7 is considered good among its contemporaries. The thrust-to-weight ratio, climb rate and acceleration ratio of the power are quite good compared to the aircraft of the same period. Although it has a static and unstable layout, a thrust-to-weight ratio of more than 1, and a fighter with a large angle of attack maneuverability, it has not fought a battle, at least it can confront the relatively low-end F-5.

The biggest problem is that even the poorest pilots can use this kind of aircraft that has no advantage (and most likely is still a disadvantage) over the opponent. Are you willing? Lacking the most basic electronic warfare warning equipment, this kind of thing is at best a discarded child that can jump twice on the battlefield.

Therefore, if you can retire from the army, it is better to do it today.

Probably around 2015, because the J-7 is too backward!

The old 7E and newer models are still very good in homeland defense, with fast speed, and powerful acceleration performance for a short period of time, which has the ability to race with the F22 (only a few minutes, of course). It is highly maneuverable, lightweight, and easy to manufacture. It can also launch active bombs under the command of AWACS aircraft (don't doubt it, Ah San's MiG-21 has already done it), and the models after the E model are also equipped with advanced combat bombs and are still good fighters at home.

So not all of them were decommissioned.

It is estimated that in another 5 to 10 years, when the number of J10 and J11 goes up or the fourth-generation aircraft appears, all of them will be retired.

Soon, when the number of J10 and J11 increases, all J7 will be retired.

It is estimated that there will be a period of time, and when I have passed the standing maturity of the third-generation fighters, it will be almost the same, and the training aircraft may still be retained.

In 2011, the J-7 fighters, which have been in service in the Chinese Air Force for many years, began to gradually withdraw from the front-line troops, and will be completely retired from the Air Force and Naval Aviation in the following years. This is because advanced aircraft (J-10, J-11, J-15, etc.) have been equipped with a large number of units of our Air Force, and the training plan for pilots has been greatly adjusted, and the training is now focused on enabling them to fly modern fighters, rather than familiarizing themselves with old fighters such as the J-7 as in the past. This has accelerated the pace of retirement of the J-7, and it is expected that in a few years, the J-7 will be fully decommissioned.

China began to be allowed to produce MiG-21 fighters in 1964, and then it took 10 years to transform the MiG-21 fighters into J-7 fighters and began mass production. The total output of J-7 fighters has exceeded 2,400 and once became China's main combat aircraft.

China is the country that uses the largest number of J-7 and MiG-21 fighters, but the J-7 fighters, which account for about 20% of the total production, are also exported to 14 other countries. The fighter is still in use in about a dozen countries.

The J-7 has no plans to be completely retired from active service, but many aircraft are automatically retired after a certain number of years of use, so the proportion of the J-7 is now gradually decreasing.

The manufacturer of J-7 is Chengfei, according to Chengfei's current production capacity, Chengfei is now producing J-10 and Thunder in all production lines, and does not produce various combat models of J-7, but there are still J-7 in production.

In addition, the J-8F is still in production, which is clear. Now, the J-10, Su-27, J-11, Su-30, Flying Leopard account for about 30-40% of all Chinese combat aircraft, and should exceed 400 units. The number of J-8Fs is difficult to determine, it should be more than 100, although it is not known whether there are more than 200.

The main ones that remain are the J-8, J-8-2 and J-7 models.

After the new fighters are equipped in place, they will be gradually retired or given to other countries.

At present, except for the G type, other models of the J-7 have been gradually retired. Although the J-7G has short legs, it has strong maneuverability and instantaneous acceleration ability is not inferior to F22With the ability to race against the F-22 for a period of time, close combat is still relatively formidable.

It is also possible to launch medium-range missiles under the command of AWACS aircraft to attack targets outside of visual range (similar to the MiG-21 of the three countries of Afghanistan launching R-50 and R-77 under the command of A-77).

For homeland air defense, the cost performance is still relatively high.

Mao, it's all old-fashioned fighters. Check not much to retire!

I feel very strange, why everyone likes to see Xiao Qi retire, and to put it bluntly, some of the combat performance of J-10 is not as good as Xiao Qi.

As a close-range combat machine, its low-cost, low-maintenance, and high-performance fighting capabilities still have its value in the current war.

For some low-intensity military tasks such as patrols, surveillance, etc., it is cost-effective in peacetime.

After the delivery of the last batch of Xiaoqi to the Nepalese Air Force, the production line of this type of aircraft has ceased to function, and the improvement work has been stopped. In the future, China's latest retired fighter will definitely be Xiaoqi, it is only a matter of time.

J-7 (codename: J-7, English: Chengdu J-7 or F-7, NATO codename:

Fishbed, Chinese: Fish Nest) is a single-seat, single-engine supersonic jet fighter manufactured by China's Shenyang Aircraft Factory (later transferred to Chengdu Aircraft Factory and Guizhou Aircraft Factory) in the 60s of the last century. The aircraft was copied and developed with reference to the Soviet MiG-21 -13 model.

The J-7 is the first two-speed sonic jet fighter developed by China, which is equipped with a large number of Chinese air force and naval aviation, mainly used for territorial air defense and seizing air supremacy on the front line of the battlefield, and can also perform ground attack missions, which is a typical second-generation fighter. The technical characteristics of the J-7 are high-altitude and high-speed, lightweight, flexible, low-cost, high-efficiency, simple use and maintenance.

In June 1973, the "3 modifications" J-7 successfully flew test, and a total of 188 aircraft (including 34 "6 modifications" J-7) were produced until the production was stopped in 1981. 40 of them came to the aid of North Korea. At the same time, the J-7 is armed with Thunderbolt-2 missiles.

In 1958, the Chinese Air Force captured two AIM-9B infrared-guided air-to-air missiles made by the U.S. Chiang Air Force in actual combat, and successfully copied the -13 missile in 1970, named the Thunderbolt-2. At one time, the unit used aviation rockets on the J-7 to intercept drones. The Thunderbolt-2 has been largely decommissioned.

The J6 was retired because it could no longer meet the needs of the operation, and it was not even easy to improve it, except for being a drone or a special test aircraft.

The J7 has not been decommissioned, although it belongs to the second generation aircraft, and the technology is backward, but its flight performance is good, especially in the state of high altitude and high speed, the implementation of local defense and key air defense is still good. In addition, now that our military spending is limited, and there are relatively few high-performance aircraft, it is very good to use the J7 to carry out conventional combat readiness and patrol missions, and flight maintenance costs can be saved a lot.

According to the current situation, the J7 may not be completely retired within ten years, so it is still being improved and a variety of improved models have been developed. After the improvement, the J7 has been improved in terms of fire control equipment, radar, and armament, and as long as the tactical command and other aspects are appropriate, it can still play a great role.

Whether a kind of first-class equipment is retired or not is definitely subject to extensive demonstration, it is a waste to be able to use it, and it is a waste to use it if it cannot be used.

J-7 is almost retired at present! The latest batch of J-7 was put into service in 2006.

Although the J-7 production line was only closed in 2013. But that's all for foreign trade, and it won't affect the decommissioning plan.

According to the law, the last batch of J-7 should be retired around 2026. However, after the military reform, especially after the expansion of military spending, the comprehensive retirement of the Jian-7 has accelerated.

According to the Air Force in March 2017, the J-7 will be completely retired by 2021, while the J-8 series will be fully decommissioned until about 2026.

However, due to the epidemic problem, I don't know if it has affected the progress of retirement. If it is affected, the complete decommissioning of the J-7 may need to be completed by the second half of 2022. If it is not affected, in the first half of 2021, the J-7 will be "extinct" in the Air Force sequence.

It's all decommissioned, what to use to fill the void in air defense! Let's top the number first, and then there will be a sufficient number of planes to retire slowly, one plane and one pit. Besides, pilots also have to be trained!

The J7 will not be retired for a few years, but it is no longer in production, as long as there is no suitable model to replace it.

Is it still useful, the main thing is that there is not so much money to change all the equipment.

After 50 years of service, why has the J-7 not been retired? You can still see it ten years later.

<> "Why is the J-7 not retired after more than 50 years of service?"

Since its invention, airplanes have always been one of the most cutting-edge technologies in the human world, and only a few countries in the world have mastered the ability to develop and produce airplanes. As an independent big country, China naturally cannot let other countries monopolize the technology of aircraft development, and since the founding of the People's Republic of China, it has been developing its own aviation stove industry, and has achieved considerable results.

In the space industry, especially the manufacture of military aircraft is very important for the national defense and security of a country. If a country can only import fighter planes, it will not only not get the world's top fighter planes, but will also be constrained by others in terms of maintenance, repair, upgrade, and other technologies.

China has always paid special attention to the research and development of fighter jets, from the initial imitation to the later self-development, has manufactured the fifth-generation aircraft J-20, and the fourth-generation and a half-generation fighter J-16 has also begun to serve in large quantities. But what is strange is that there are still many older fighters in China's air force, such as J-7, why is this?

The J-7 is a replica of the MiG-21 fighter in China, which has been in service for more than 50 years. As one of the most successful fighters imitated by our country, the J-7 has not only made a significant contribution to our country's national defense, but also exported to countries around the world. However, for the development of fighters, the J-7 model is very old, but China has not completely retired these fighters, why is this?

In fact, there are three main reasons, one of which is that it is unrealistic to replace a large number of fighters with the latest models, which requires our economic development to reach a higher level.

The second is because we also need these J-7 fighters to train fighter pilots. The training of Air Force pilots consumes a lot of time and money. When China is training fighter pilots, it is impossible to use all the J-16 and J-20 for practice, and these J-7 that have not yet been retired have become the best training fighters.

Just as many of our troops are still using the previous wooden-handled grenades for bomb throwing training, these J-7s have also played such a role, which is not unimportant.

The last point is that the J-7 has many advantages, such as a small failure rate, relatively simple structure and maintenance, and relatively low manufacturing costs. These advantages make the J-7 very "inexpensive", and these J-7 play their role when carrying out some daily air defense and patrol tasks.

The use of a large number of J-7 for daily tasks can reduce the loss of advanced fighters, as the so-called "good steel is used on the blade", J-20 and other advanced fighters will be China's sharpest knives, in the most critical moment to play their role. The J-7 can also understand that China still has many shortcomings to make up. Of course, our country will also complete the replacement of fighters as soon as possible, so that our blue sky will be guarded by more and more advanced fighters, and these J-7s can also successfully complete their historical mission.

According to 2004, a flight was completed.

According to the data released at the Chengfei Centennial Achievement Exhibition, the production quantity of various types of the J-7 family is: J-7i = 187 aircraft, including 40 military aid to North Korea J-7II = 273 aircraft J-7A = 20 aircraft exported to Egypt J-7M = 63 aircraft, exported to Jordan.

60 aircraft, 1 exported to the United States J-7IIK = 58 J-7BS = exported to Sri Lanka.

4 J-7D = 32 (that is, J-7III, due to poor performance, the number of J-7D was re-assigned when the military aircraft numbering rules were changed) J-7II = 40 exported to Egypt and 15 to the United States (sold to Iraq through the United States. Zimbabwe.

15 J-7IIH = 221 J-7E = 263 J-7EH = 34 J-7N = 30 exported to Iran J-7IIN = 8 exported to Zimbabwe J-7P = 112 exported to Pakistan J-7PG = 48 exported to Pakistan In this way, by the summer of 2004, the total production number of the J-7 family that had been flying was more than 1,500 aircraft, excluding more than 500 aircraft exported and about 1,000 aircraft for self-use (Air Force + HNA). Among these 1,000 aircraft, minus those retired due to various reasons such as damage, crashes, and aging of the airframe, there should be more than 800 left. Among these more than 800 aircraft, there is still a certain number of strategic reserves, assuming that its number can be equipped with two aviation divisions, then the number should be about 150-200 aircraft, so that the number of Jian-7 aircraft in active service equipment of the army should be about 600-650 aircraft.

In the above flight data, the production quantity of J-7G and J-7GB is not given, but from the military newspaper report in 04-08, the Air 37 Division and the Air 12 Division were reequipped with a J-7G combat regiment in 2004 and 2006 respectively, and the J-7GB of the 81 performance team was modified from the J-7G transferred from the Air Force Strategic Reserve Center, so it can be estimated that by the end of 2007, the J-7G has produced about 120-150 aircraft (48 aircraft in 2 regiments + 48 aircraft in the same number =96 - 81 teams allocated 12 = 84 = 37 other 2 regiments that may be reequipped = 132 aircraft), in this way, the number of J-7 types in service should be more than 700-800 (600 + 24x3 = 672, 650 + 24x3 = 672). However, considering that the J-10 produced about 200 equipped Air Force aircraft to replace the old aircraft (considering that the Air Force did not have the J-6 combat regiment at the end of 04, it should be used to replace the old J-7), so the number of J-7 in active service is about 500-600.
