After four years of probation in 1996 after the introduction of production of China and Russia signed two hundred at the most advanced Russian SU-27SK air superiority fighter. Shenyang Aircraft Corporation in the establishment of an independent production facilities in the J-8 fighter's new advanced plant, with the West and the domestic most advanced production equipment, copying machine, so its quality is better than the Russian machine production process and lay a solid foundation for further improvements , a move that Shen production technology and aircraft performance to fly almost leap Nianwu years.

1999 made the first degree of Qicheng fighter factory, renamed the F-11, and imitation works except the engine is balanced, almost all domestic and local improvement for the F-11A, at home and abroad since the nineties aviation technology, especially the rapid development of electronic technology, SU-27 / J 11, has quickly behind the troops to their lack of humanity, avionics J-8 is also out of date than the new, low reliability, complaining of the community, the results of Shen flying in the assembly ninety-five J-11 after being forced to stop production, the Russian side to this full of doubts.

In fact, after several years of honing elite Air China, has been fully digested and absorbed the essence of SU-27, made a bold leap forward, aerodynamic shape than all but the most advanced equipment to switch the computer made the design of national key projects, namely, the F-11B aircraft Secret launched two years, and the full use of Western military standards.

Hong sent to production only seven

As the aircraft was not formally declassified, rumors of a few mistakes the West. F-11B is actually designed from the start of production in just seven years since the end of a large number of its large volume change is tantamount to re-Hong system, the speed of China's aviation science and technology can be seen, so that the U.S. and Russia and other powers shared by surprise. Russia to sell to China many times the latest modified SU-27SKM got no reply, because it is the Chinese side has the same technology. Russia was forced to admit the end of the independent production of China has improved a 11B, the Russian side did not understand the actual situation that misjudgment; the same sources the formal shape of the F-11B has delivered the second batch of last year, seventeen.

Resin-based composite materials using the J-11B significantly reduce the weight of more than seven hundred kilograms, and for the development of carrier-based free up valuable weight; with thrust greater than the Russian version of the Taihang engine, air combat performance than the already excellent The SU-27 a higher level, the body life of more than ten thousand hours than the latter that is more than three decades of alarming proportions. In addition airborne equipment including environmental control system, full authority telex four flight control system redundancy, fire control systems, glass cockpit, carbon-carbon brake system so the whole system is self Subcommittee to the most advanced equipment than the SU-27 about twenty leading years.

Sight over the Russian-made helmet

Matching helmet display and optical sensors, has been replaced by digital equipment, the reliability of poorly made much adverse comment in Russian goods. Ministry of Information Development 1471 14 multi-function fire control radar, the radar is an upgraded version of J-101473; can simultaneously track the twenty targets, the missile attacks on six goals, has reached the highest level of mechanical scanning radar. Mount up to eight of the PL-12 medium-range interception missile, anti-interference ability and overall performance is better than the Russian-made SU-30MKK fighter R-77 air to air missiles.

Yet have not reached the standard stealth

At the same time also pay attention to the West exaggerated rhetoric. F-11B as the strongest in the radar reflectivity install 屛 shelter inlet lip cover, also in the inlet radar absorbing paint, so that the aircraft radar reflectivity cross section from the SU-27's sharp decline in three fifteen square meters times to five meters is not enough to improve aerodynamic shape without conditions, has reached the limits of current human can do. But still with a small F-16 square meters have a wide gap, more not less than one square meter invisible to standard as a stealth aircraft can not, unless someone render China threat theory.

According to the CMC requirements, this close to the western half of three generations (four generations plus Russia) standard best fighter, the performance to achieve the first, world-class level, and the formal shape of this year to prepare for mass production.

J-11B production of stereotypes, will further significantly reduce the gap with advanced power, is the second after the J-10 is worthy of another successful development by leaps and bounds proud masterpiece. Its comprehensive combat is six times that J-10, SU-27 is six times as much.
