FANTAN Variants - Q-5D / Q-5J / Q-5K / Q-5KLJ
- Q-5D was developed after the Q-5M was discontinued in 1989, on the Q-5C foundation, and first flew in 1990. The People's Liberation Army once planned upgrades that the Q-5M used, but for various reasons, such as shortage of funds, had not implemented. The Q-5D electronic installation's improvement take two central digital computers and a double redundancy data bus as the core, with addition modernization of the guidance and the attack system. The new sensing installation and the equipment including inertial navigation system, collimated display, atmosphere electrodata machine, three degree-of-freedom cluster of gyros, the distance-measuring radar, the RW-30 radar security receiver, the attitude indicator, the horizontal situation indicator, the static converter and the modality meet the regulator, but also has the new hardware with 8 item of original device attachment interface equipment which retains. There were also improvements in cooling systems and power source, fuel oil, electronic warfare, and illumination. In order to hold some of the new equipment outside the fuselage, and to avoid a big design revision to the airplane's nose, suitable structural revisions were made to the outboard wing. The project work was completed in June 1987, with changed quantity of 28.8%.
- Q-5J double seat training attack airplane was displayed for the first time in October 2004 at the Shenzhen China Hi-tech Fair. The factory said that this JQ-5J may serve as a weapon training the platform, also for portable precision guided munitions, while simultaneously it may also carry out a unit's other training tasks. The manufacturer claimed that it can be used as forward air control like the OA-10A, and providing targeting information via data links. The rear seat is 286 millimetres higher than the front seat, enables the back-seat pilot to have a 5 degree field of vision, and the canopy opens to the right. When used as a trainer, the rear cockpit control can override that of the front cockpit. Because the JJ-6 had been responsible for the Q-5 training duties, over the years a Q-5 redesign for a strongly specialized two-place trainer had not been needed. But with the JJ-6 being released from active duty, the Q-5 actually was still a main force type, and there was a need to train Q-5 pilots. So the Q-5J may possibly become the only choice for the air force in the future.
- Q-5K Kong Yun: (Kong Yun - Cloud) was a joint Chinese-French project to further upgrade Q-5II with Sa Jim company's French Thomsen Company avionics. This included the as VE110 collimated head-Up Display, ULIS91 inertial navigation system, TMV630 laser rangefinder and other electro-optics. Like the Q-5M/A-5M, the project was also cancelled after the Tiananmen Square protest of 1989. The test flight of this machine in 1991 was successful.
- Q-5KLJ ? is a variant of unknown designation displayed in mockup in April 2008 by the Nanjing Electronic technology Research institute. The model airborne weapon carries had a new look, as on its wing tip were two air-to-air missiles, under the underbelly also increased two row of weapon racks, with four un-guided bombs. The model nose demonstrated that this machine will equip the KLJ-7 fire control radar. It used the Q-5 improved with the domestically produced KLJ-7 radar. This radar was developed by the Nanjing Electronic technology Research institute. This radar is a multi-purpose X wave band pulse Doppler fire control radar, which uses the high, middle and low pulse rate. The entire design has overall height omni-directionally, all-weather target detection, track capacity. It uses the 1553B main bus and the compound video frequency and fire control system crossing linking supplies the essential information for it. It completes identification of friend or foe [IFF ] system coordination. It coordinate control naval gun, dogfight missile, rocket projectile and bomb's launch and delivery, and completes the intermediate-range missile guidance.
