China is retiring J-7 jet from front line service
in 2009, China finally stopped the production of J-7G, the last variant of Mig-21 jet.
China has officially withdrawn its MiG-21 clone (the J-7) from first line service. This comes as no surprise. In the last four years China has more than doubled the number of modern combat aircraft (J-10, J-11, Su-27, Su-30, and J-8F) from 500 to over 1,200. Four years ago China relied mainly on some 2,000 locally built copies of Russian MiG-19s (J-6) and MiG-21 (J-7). There are still several hundred bombers mostly Russian knockoffs. Normally, the actual number of Chinese aircraft is a state secret. However, thanks to the ability of Chinese to move freely throughout the country and access to the Internet it's possible to locate and count all the air force units in the country. That shows a current force that is rapidly changing from one that is mostly MiG-21s and MiG-19s, to one composed of much more capable aircraft. China is buying and building a lot of the Russian Su-27s and Su-30s (the latter an upgrade of the former.) But new, home grown designs, like the J-20 are also showing up.
Another reason for withdrawing the J-7 to secondary regions (where modern jets are unlikely to be encountered) is the inability to use J-7s for a lot of training. That's important because China is revising its combat pilot training program. The existing system takes ten years of academic and flight training. The new program cuts that to 5-7 years, while increasing flight hours by over 40 percent. This is more in line with Western methods, while the existing system owes more to the one the Russians developed during the Cold War. The new system puts more emphasis on trainee pilots demonstrating combat flying skills before they can graduate. Cold War era Russian aircraft designs, like the MiG-21, were not designed for the heavy use required for Western style pilot training.
The new training program is actually an evolution of the need for new training methods to prepare pilots to handle the more modern aircraft. Training for pilots of these new fighters has been more intense than for any previous aircraft. In addition, China is also holding training exercises directed at fighting other modern fighters, like those flown by Taiwan, Japan, and the United States. China is not keeping much of this secret and that is apparently sending a message to potential foes.
China has long been the largest user of the MiG-21 in the form of their J-7 clone. China still exports J-7s but has been rapidly retiring the ones remaining in Chinese service. The J-7 was, in many ways, the most advanced version of the MiG-21, as the Chinese kept improving their J-7 design. Over 10,000 Mig-21s and J-7s have been produced in the last sixty years, making this the most widely manufactured jet fighter of the last century (during World War II there were several propeller driven fighters that were produced in greater numbers.) The MiG-21 looked fearsome but it was a bust in combat, getting shot down more often than not. Russia still had 186 Mig-21s in service when the Soviet Union dissolved in 1991s. These MiG-21s were officially retired a few years later. India, the last major user of the MiG-21, is in the process of retiring them as well.
