Built in 1970, it covers an area of 310,000 square meters.

History

In May 1970, the Shenyang design team for the J-9 moved to Chengdu; this was part of the "Third Line" program that moved defence industries to the interior to make them less vulnerable to foreign attack. The team was later renamed as the 611 Institute.^[2]

The design work on the cancelled double-canard J-9 influenced later CADI designs.^[2]^[3] The Chengdu J-10 used the double-canard layout.^[2] The Chengdu J-20 also used canards.^[3]
