Design and developmentEdit
Although the MiG-19 had a comparatively short life in Soviet service, the Chinese came to value its agility, turning performance, and powerful cannon armament, and produced it for their own use between 1958 and 1981. While the basic Soviet-built MiG-19 has been retired from all nations, the Shenyang J-6 still flies for nine of its original 15 operators, however, in a very limited capacity. The J-6 airframe contributed to the Chinese ground attack version, the Q-5, which still flies for numerous nations.
The J-6 was considered "disposable" and was intended to be operated for only 100 flight hours (or approximately 100 sorties) before being overhauled. The Pakistan Air Force was often able to extend this to 130 hours with diligent maintenance.
The J-6 has a maximum speed at altitude of 1,540 km/h (960 mph), Mach 1.45. Service ceiling is 17,900 m (58,700 ft). Combat radius with two drop tanks is about 640 km (400 mi). Powerplant is two Liming Wopen-6A (Tumansky R-9) turbojet engines. In addition to the internal cannon armament, most have provision for four wing pylons for up to 250 kg (550 lb) each, with a maximum ordnance load of 500 kg (1,100 lb). Typical stores include unguided bombs, 55 mm rocket pods, or PL-2/PL-5 (Chinese versions of Soviet K-13 (NATO AA-2 'Atoll') air-to-air missiles.
Albanian Air Force J-6s replaced the J-5s on the border to intercept Yugoslav incursions into Albanian airspace. However, the J-6 was ineffective against the faster Yugoslav MiG-21 'Fishbed'. Once the F-7A became available, the J-6 was redeployed to guard Tirana. As of 2005 all Albanian fighters were grounded due to lack of spare parts.
The F-6 was flown by the Pakistan Air Force from 1965 to 2002, the aircraft design undergoing around 140 modifications to improve its capabilities in the interceptor and close air support roles. The PAF F-6 fighters participated in the Indo-Pak War 1971 against India, scoring approximately 6 confirmed aerial victories. Moreover, these were extensively used in Close Air Support role where their 3 x 30 mm guns were particularly effective against Armour. The three Pakistani J-6 squadrons flew nearly a thousand sorties, during which the PAF lost 2 F-6 to ground fire and suffered two losses in aerial combat, attributed to Indian Sukhoi Su-7's. An F-6 was also lost to friendly fire. One of the F-6 pilots shot down was Wajid Ali Khan, who was taken as a POW and later became a Member of Parliament in Canada. The single seat F-6 was retired from the Pakistani Air Force in 2002, but the two-seat trainer, the FT-6, remained in service as trainers for Nanchang Q-5 till 2011.
The supersonic speed advantage provided by the MiG-21's more modern turbojet engine was found to be not as useful in combat as originally thought, because aerial dogfights at the time were conducted almost entirely in the sub-sonic speed regime. The J-6 (and hence the MiG-19 also) was found to be more manoeuvrable than the MiG-21 and, although slower, its acceleration during dogfights was considered adequate. The North Vietnamese Air Force fielded at least one unit of J-6 during the war, the 925th Fighter Regiment, beginning in 1969.
Somalian J-6s participated in the 1977-1978 Ogaden War and suffered greatly because of the superior opposition faced (Cuban pilots fought for Ethiopia). Over 75% of the Somali Air Force was destroyed in the war but some J-6s survived until the country turned into turmoil in the early 1990s.
During the 1978-1979 Uganda-Tanzania War, Tanzanian J-6s and Shenyang F-5s were tasked to handle any possible Ugandan fighters which consisted of MiG-15s and MiG-17s, while F-7As were tasked to handle more advanced aircraft of Ugandan allies, such as the Libyan Tupolev Tu-22 'Blinder'.
In the era of Khmer Rouge control of Cambodia (1975-1979), Chinese-supplied Khmer J-6s participated in Kampuchea-Vietnamese border clashes for ground attacks. During the Vietnamese invasion in 1978, the Cambodian aircraft were reluctant to take-off to intercept the Vietnamese ones, thus the Vietnamese captured a number of J-6s and put them on public display.
During the 1980–88 Iran–Iraq War, both sides deployed J-6 fighter jets. Documents from the US Defense Intelligence Agency released under the Freedom of Information Act (United States) on Chinese arms sales to Iran reveal that between 1980-87 China delivered 100 J-6 fighter jets to Iran. Iraq's J-6 fighters were transferred from the Egyptian Air Force. Most missions J-6s performed during the Iran-Iraq War were air-to-ground attack.
- Shenyang J-6 – (a.k.a. Type 59, Dongfeng-102, Product 47 and F-6) Despite having no suffix to the designation, the J-6 appeared after the initial production of the J-6A had begun. The J-6 was equivalent, but not identical, to the MiG-19S.
- Shenyang J-6A – (a.k.a. Type 59A, Dongfeng-103, Jianjiji-6 Jia) – Early production from 1958 to 1960 was sub-standard and not accepted by the PLAAF. Production was halted, the jigs scrapped, and production restarted with assistance from the USSR. The J-6A was equivalent to the MiG-19P. The maiden flight was made by Wang Shuhuai on 17 December 1958. The total production figure for this variant was only one hundred or so. It was reported that J-6A, along with J-8B, never actually passed PLAAF's test. The planes suffered from quality issues, flight characteristics were much lower than J-6, and were of little operational value.
- Shenyang J-6A – Production of the J-6 restarted after new assembly jigs, and other assistance, acquired from the USSR. Similar to MiG-19PF, an all-weather radar-equipped interceptor with two NR-30 30mm cannon. Exported as the F-6A.
- J-6B – (a.k.a. Type 59B, Dongfeng-105 and Jianjiji-6 Yi) Similar to MiG-19PM "Farmer-D", interceptor with two PL-1 (Chinese version of Soviet K-5 (AA-1 'Alkali') beam-riding air-to-air missiles; it is unclear if the J-6B retains its cannon. Only 19 J-6B's were built by Nanchang Aircraft Mfg. Co. before the programme was terminated.
- J-6C – (a.k.a. Jianjiji-6 Bing, Product 55 and F-6C) Day fighter version with three 30mm cannon and braking parachute at the base of the rudder. This cannon's code name is Type 30-1. Firing at 850 rounds per minute, it is effective against large aircraft with its armor-piercing and high-explosive ammunitions.
- Shenyang J-6I – Single-seat day-fighter prototype with fixed shock cone on the intake splitter plate.
- Shenyang J-6II – Single-seat tactical fighter prototype with adjustable shock cone on a raked back intake splitter plate.
- Shenyang J-6III – Advanced version of the J-6A with radome on the splitter plate (rather than the shock cone centerbody) for a Chinese-made radar. May also have been designated J-6 Xin.
- Shenyang/Tianjin JJ-6 – (Jianjiji Jiaolianji – fighter trainer, a.k.a. Product 48 and FT-6) Chinese designed two-seat trainer, stretched 84 cm (33.1 in) to accommodate second seat, armed with one 30 mm cannon.
- Shenyang JZ-6 – (Jianjiji Zhenchaji – reconnaissance fighter) Dedicated reconnaissance version with fuselage camera pack replacing cannon. As of April 2006, it was reported that the PLAAF 3rd Recon Regiment, 26 Air Division based in Nanjing MR, is the last regiment to actively fly the JZ-6 refusing to convert to JZ-8F. Exported as the Shenyang FR-6.
- Shenyang/Tianjin JJ-6 Testbed – Ejection seat testbed that succeeded H-5 ejection seat testbed.
