The Swedish Air Force needed more air defense during World War II. They bought Italian fighters like the Fiat C.R.42. Later, the J-11 was created. It was used primarily as a fighter aircraft, but it was also capable of being used as an scout/recon car.
Shenyang Aircraft Corporation developed the Shenyang J-11, which was contracted by China to make jet fighters for its border. The Sukhoi Su-27 Su-27, a Soviet-designed air superiority fighter, was the base of the aircraft's aeroframe. China developed the J-11 as a version of the Su-27SK under license. After the contract expired the Shenyang Aircraft Corporation began manufacturing the J-11s.
The J-11's glass cockpit features a digital flight controller system, a head up display, emergency warning equipment, and colour multifunctional displays. The aircraft also features an integrated multifunctional pulse-Doppler radar, an attitude and heading system, and an indigenous multifunctional pulse Doppler radar. Two machine guns of 12.7 mm Akan size m/40 are available to the aircraft. It features a flight data recording system (FIRS), as well as an attitude and heading system (AGRS). It can be used by one pilot.
The J-11 has an extremely high top speed. The J-11's ability to climb long distances makes it very difficult for other biplanes. It can also be equipped with advanced air to-air missiles, such as PL-10. The J-11 can also be equipped with a TS101M processor, which can simultaneously track 10 targets. It features an IFF system interrogator and a helmet mounted sight.
People's Liberation Army Air Force operates the J-11. The J-11B upgraded version of J-11B comes equipped with a Chinese made WS-10A "Taihang” turbofan. This aircraft has a higher battle rating, 1.7 (AB). Also, the J-11B was used in testing of the WS-10. CCTV-7, a state TV station, aired footages of J-11B between 2007 and 2008.
The J-11B, the first J-11 equipped in China with Chinese hardware, is it? Chinese web sources claim that electronic components of the aircraft's electronics (avionics and radar) are Chinese. Reports also claim that the engines of the aircraft are made in China. China has not yet integrated an AESA-radar into the J-11.
The J-11 is equipped with a powerful landing brake that can be softened to prevent plane crashes. The J-11's heavy steel structure means it can travel at high speeds. The J11's nose might overshoot because of its powerful engine. The J-11 can outrun all other biplanes in its class.
The Chinese military has been looking for a replacement to its fourth-generation fighters. The J-20 was an option, but it is costly and unpredictable. The J-11D will be a complement to J-20 for many decades. It is expected that it will integrate an active electronically scanned radar (AESA), which is a miniaturized electronic scanner array. Composite materials will also be installed in the wings, tail and tail. The J-11D also has radar absorbent coatings.
