GlobalConflictहिंदी's video: J-10 Vs Jas-39: Gripen jet Chinese Air Force

The Saab JAS 39 Gripen is a light single-engine multirole fighter aircraft manufactured by the Swedish aerospace company Saab AB. The Gripen has a delta wing and canard configuration with relaxed stability design and fly-by-wire flight controls. Various versions have been built, grouped as A-, C- and E-series. Gripen A- and C-series are powered by the GE F404G engine (previously designated Volvo RM12) and the E-series is powered by the GE F414G engine, and has a top speed of Mach 2. Later aircraft are modified for NATO interoperability standards and air-to-air refuelling. In 1979, the Swedish government began development studies for an aircraft capable of fighter, attack, and reconnaissance missions to replace the Saab 35 Draken and 37 Viggen in the Swedish Air Force. A new design from Saab was selected and developed as the JAS 39, first flying in 1988, delivery of first serial production airplane occurred in 1993, and entered service with the Swedish Air Force in 1996. Upgraded variants, featuring more advanced avionics and adaptations for longer mission times, began entering service in 2003. To market the aircraft internationally, Saab formed partnerships and collaborative efforts with overseas aerospace companies, including, in 2001, BAE Systems. On the export market, early models of the Gripen achieved moderate success in sales to nations in Central Europe, South Africa, and Southeast Asia; bribery was suspected in some of these procurements, but authorities closed the investigation in 2009. The Shenyang J-11 is a twin-engine jet fighter whose airframe is based on the Soviet-designed Sukhoi Su-27. It is manufactured by the Shenyang Aircraft Corporation (SAC). The aircraft is operated by the People's Liberation Army Air Force (PLAAF) and the People's Liberation Army Naval Air Force (PLANAF). The J-11B is a multirole variant of the J-11 incorporating Chinese subsystems. It was conceived as a way to remove the J-11's dependency on Russia. SAC unveiled a J-11B mockup in mid-2002. Three prototypes were delivered to the PLAAF for testing in 2006. The two-seater J-11BS followed two years after the J-11B. By 2011, reportedly 90% of the J-11B was based on subsystems and parts designed in China, with the engine presumably being a major part of the remainder. Many domestic subsystems are improvements of those found on the Su-27SK. Chinese subsystems on the J-11B include Type 1474 radar, 3-axis data system, power supply system, emergency power unit, brake system, hydraulic system, fuel system, environment control system, molecular sieve oxygen generation systems, digital flight control system, and glass cockpit. The IRST is a Chinese copy of the Russian OEPS-27. The airframe is slightly lighter due to greater use of composites.
