The J 10 started off as a Chinese attempt at reverse engineering a Pakistan bought US F-16. However it ended up being a modification of Israel’s Lavi multi role fighter, Lavi program was cancelled in 1987 in Israel due to threatening from US. China purchased the blue print from Israel and developed J 10.
The J 10 is one of the Chinese backbone Fighter jet to perform defensive mission inside Chinese Air-space. The Chinese Air force operates more than 250 J 10 variants which comprises more than twelve squadron of Fighter’s with 70% of service availability at any given time. The J 10 is one of the Chinese designed Fighter jets based on the cancelled Israeli Lavi program. J 10 is a single engine multi role, which can be modified in future with newer Radar and power plants.
The J 10 is almost identical to the American F 16, Who is also a light multi role all weather Fighter jets and J10-B it possesses advantages as compared with the third-generation fighters of China’s neighboring countries and the 3.5-generation fighters deployed in the Asia Pacific Region by the U.S., namely the J-10B fighter possesses advantages and does not lag behind.
J10-B is medium-scale 3.5-generation fighter with a maximum take-off weight of 19 tons, a bomb load between 6 and 8 tons, a combat radius of about 1,000 kilometers and a flight speed between 1 and 1.5 mach, which is a modified model of the J-10A fighter, is equipped with an active phased-array radar and capable of carrying air-to-air missiles.
The detail of J 10 is hardly available. From the available data it’s very clear that Tejas is not inferior to J 10. J 10 has advantage in weapon loads; range etc only because it is a bigger aircraft so J10 can carry more weapons.
The important feature in the J 10 B is the Divert less supersonic air intake and the larger radome to house bigger AESA or phased array radar. The Aerospace engineers claim the DSI is used to control the fighter jet in Supersonic speed and superior boundary layer air flow.
