The JJ-6 (Jianji Jiaolian-6, or JianJiao-6) developed by the Shenyang Aircraft Corporation (SAC) is the two seat fighter-trainer variant of the J-6 (MiG-19 Farmer) fighter. The aircraft has been operated by the PLAAF and PLA Naval Aviation for the training of fighter and attacker pilots. Only a very small number JJ-6s are still airworthy these days and they are likely to be completely retired from active service in the near future.
Development of the two-seat trainer variant of the J-6 fighter began in 1966. The first flight took place on 6 November 1970. The aircraft design was certified in December 1973 and the production began in 1976. A total of 624 examples were built before the production stopped in 1986. It is noticeable that the JJ-6 is the only operational two-seat version in the MiG-19/J-6 Farmer series as the Soviet Air Force did not have a two-seat variant MiG-19. The PLAAF also developed BW-1 fly-by-wire testbed and rocket ejection seat testbed on the basis of the JJ-6.
Compared to the original J-6, the JJ-6 has a slightly stretched fuselage to provide volume for the insertion of a tandem-seat cockpit. The rear trainer seat is slightly higher than the front student seat to provide a better view. Only one wing-root 30mm cannon is remained. The original single under-fuselage stabilising fin on the J-6 was replaced by a two-fin design to improve its aerodynamic performance. The aircraft is also equipped with internal communication system, beacons, radio altimeter, and a gun camera for training purpose.
The JJ-6 has a 30mm cannon located at the wing-root. Two under-wing pylons can carry unguided rocket launchers to attack air or ground targets.
