The J-6A (Chinese: 歼-6甲型歼击机; Type 59 Interceptor 五九式歼击机 before new naming), sharing the NATO codename of "Farmer" with its Soviet counterpart since it was a licensed build of the MiG-19 series, was the main fighter jet of the PLAAF since the early 1960s. As the first country to build supersonic jets in Asia, the J-6 and its different variants were in service with the PLAAF for nearly 4 decades before they were finally replaced by new jets. Although already deemed obsolete by the time the F-104 and MiG-21 series joined their respective air forces, the J-6 scored some victories over the ROCAF and US(N)AF against their jets and drones, as well as overseas victories by other users. The jet also served as a platform of different prototypes, and was the predecessor of the Nanchang Q-5, with 60% of the parts interchangeable.

Introduced to the game alongside the Chinese tech tree in Update 1.91 "Night Vision", the J-6 plays identically to the MiG-19PT previously introduced about a year earlier. The immense acceleration paired with its firepower strike fear in subsonic jets that cannot chase it; but do beware of its subpar manoeuvrability at transonic speeds where it will have a hard time pulling out from dives. Although it can face more advanced jets such as MiG-21s and Phantoms, if players are able to lure them into a dogfight, the 30 mm cannons will never disappoint as they can tear down enemy targets with ease; alternatively, the PL-2 missiles can also prove effective if they have used up all their energy/flares to escape from the inevitable.
