As we all know, China since 1977, code-named X-600 project. In 1985 a small turbofan engine has been tested. The first in the 600 km range cruise missiles in service in 1992, this missile is named the Red Bird 1. Currently, the Red Bird Red Bird series has been developed to 3, increased from the initial range of 600 km to 3,000 km. Australia's Defence Weekly, said the Chinese J-11 fighters carrying red birds missiles, the U.S. Pacific Fleet in Tashi had to back away.

As early as 2005, began a large-scale domestic and international speculation that China's Red Bird 2000 cruise missiles, estimated range of 4,000 kilometers, performance, and the U.S. Tomahawk quite. With the Chinese anti-ship ballistic missiles guess more and more speculation that the Chinese anti-ship cruise missiles are also flourishing. Red Bird 3, divided into land-launched (HN-3A), ship radio (submarine) type (HN-3B), and air-launched (HN-3C), air-launched by JH -7, F-8IIM and F -11 to launch platform. Red Bird in 2000 at home and abroad have speculated air-launched anti-ship cruise missiles bound for J -11 as the main launch platform.
　
Red Bird 3, range between 2000-3000 km. Speed of 0.9 Mach, cruise altitude from 10 to 8000 meters. Whole weight 1,400 kg. Guidance and Red Bird 2, the same accuracy has increased, in the 2 m circular error probability + / -30%. In 1998 a small amount of troops and equipment validation. PLA submarine may be equipped with nuclear-powered attack submarines on the 093. Red Bird in 2000 at home and abroad have speculated air-launched anti-ship cruise missiles with a range of 4,000 kilometers, the main targets for the design of the sea, instead of attacking land targets. F-11 put up the "Red Bird 2000" anti-ship cruise missiles against U.S. aircraft carrier is a great threat.

Red Bird 2, divided into land-launched (HN-2A / B, range 1800) and submarine (HN-2C, a range of 1,400 km), the guide means the same as No. 1 and Red Bird, the submarine is equipped with the Type 039 submarines, and can be installed in the submarine's 533 mm torpedo tubes to launch vertically. The guided missile in the way of the Red Bird 1 is basically the same, the ideal 3-meter accuracy, speed of 0.9 Mach, cruise 15-7000 m altitude. Whole weight 1,400 kg. Equipment of the army in 1996.
Red Bird 1, divided into land-launched (HN-1A, 600 km range) and air-launched (HN-1B, a range of 650 km.) Conducted in 1988 snatched the first low-altitude surface missile tests in 1992, the armed forces. Red Bird 1 shape and similar to the Russian Kh-55 with two straight after the break of the wing can be folded vertical tail, horizontal tail end of the missile body. Can carry a 300-400 kg warhead or nine traditional power kiloton nuclear warhead, the guidance is adopted the middle of inertial guidance (INS), Global Positioning System (GPS), to sub-maps (1994 type), and use TV camera device with the target calibration correction (1994 night type), in poor visibility conditions, a round hit probability of error of 5 meters, but this story may be too optimistic. The missile can be controlled radio altimeter altitude of 20 meters. Engine installed in the rear, air intake below the projectile. The missile length of 6.4 meters, wingspan of 3 meters, 0.520 meters in diameter and weighs 1,400 kg, warhead weight 300-400 kg. Speed of 0.75 Mach, cruise altitude of 20 to 6,000 meters. China H-6D aircraft can be equipped with two of the cruise missile.

China to improve on su-27 su-35 so as to achieve the level of the su-30kk is su-35 technological improvements made. F-11B is very good, avionics system has been at or near the level of the F-10A. In the body structure, avionics improvements in this area, and our own than the Russian radar, although there are a certain distance, but better than in Russia sell to us, and the task function is not limited. However, the expense of the use of improved overload, maximum speed, the maximum ceiling performance in these areas faced .11 B is now the main problem is with the hard body structure and electric control system is not good change.

SU27 overload is only 7.5g, is that a speed of about 0 su27 easy to stall caused, J11 facelift domestic digital flight control has been changing for the better after the long pull.

J11B 153 used in advanced electronic equipment, all were developed for the first time made the latest electronic equipment; August 23, 2001, an aircraft avionics system made plans to open a 601 model made the third graph the main battlefield. The focus of the Ministry of Reconstruction of the entire model aircraft design avionics system, the task is arduous. But they overcome difficulties, heavy responsibilities, and a race against time. After 7 months, worked hard, was a monk? At the end of time to complete a certain type of aircraft avionics systems issue such plans work, the drawings were issued more than 20,000 A4. Completed after a type of aircraft avionics system designs typically require two years, while the 601 only took less than 8 months!

Maximum range of 11 F (air refueling time) should be 5,200 km, J10 radar diameter is 680, J11 I do not say it. J11 is 980; 14 development.

J11B the forward-looking infrared detection system with a self-inspection / repair system project, J11B inside the equipment into the domestic. Relative to SK, the transformation is reborn. Maintenance of a substantial increase; F-11B has been made with new electronic interference device, similar to the f18 thing above; J11 set coefficient of oil 37%; J11B body life 1500 hours.

F-11 fighter program in China will be 30 years, from 90 to 2020, F-10 military will not buy more than 150 temporary, may be mainly used with the export, the project will be equipped with F-11 of about 700 as China in the 21st century 20 the main force in the absolute. With anti-radiation missile capability, equipped with new series of anti-radiation missiles and a thunderbolt eagle series anti-radiation missile (J-11 Thunderbolt hang-12x2R27x4, R73x4) improved ground attack capabilities and a wide variety of ground attack munitions, including cluster bombs guided and laser-guided microwave, TV-guided bombs and fired to complete the seamless floor, equipped with devices to distribute landmines scattered.

F-11 with external fuel tanks, with aerial refueling capability, the most important is the latest automatic detection system, a new supply trailer systems, more suitable for air transport. J10 J11 is about two-thirds the cost.
