In 2000, China purchased an Su-30MKK from Russia, which formed the basis for development of two-seat J-11 variants. The Chinese developed the two-seat J-11BS into a dedicated strike fighter under the designation J-16.
Just as its predecessor, it extensively employs composites to lower airframe weight, while new materials and design elements were used to lower RCS. The J-16 first took flight in 2011 and was accepted into service two years later.
A small production of only 25 aircraft built. While still in production, priority seems to be placed on development and production of the fifth-generation J-20 and J-31 fighters.
