Rattles and Tigers
Pakistan



In 1969 in the Pakistan Air Force, a “Rattles” aerobatic display team was created at Sargodha Air Base flying with Shenyang F-6 (a Chinese-built MiG-19) fighters which were painted all black. The team existed for only a few months.

In 1980, another F-6 (MiG-19) aerobatic team, known as the “Tigers”, was created at Sargodha. This time all 5 aircraft were painted in special colors - yellow and red. This team lasted a little longer than its predecessor.

JF-17 Thunder – Lightning Strikes Twice
by Alan Warnes
- June 15, 2019, 3:30 AM


The Pak-Sino JF-17 Thunder has flown over 40,000 hours in service with six squadrons, including 2 ‘Minhasians’ Sqn. The fighter is set to mature even more rapidly with the integration of an AESA radar in the Block 3 JF-17s. (Photos: Alan Warnes)
Three Pakistan Air Force (PAF) JF-17s are attending this year’s Paris Air Show. The type will be making a welcome visit after the Pak-Sino-developed Thunder visited the event in 2015, and a lot has happened to the program since then.

Right now the last three Block 2s are on the Aircraft Manufacturing Factory (AMF) final assembly line at Pakistan Aeronautical Complex (PAC) Kamra, which will eventually help to equip a seventh operational unit later this year. Meanwhile, the first JF-17 has undergone a major overhaul at PAC Kamra’s Aircraft Repair Factory, and there is a dual-seat JF-17B, 17-601, undergoing test and evaluation in Pakistan. A decision from the PAF leadership on a new AESA radar for the Block 3 JF-17s is pending and is expected by November, followed by its first operational sortie early next year. Then, in deals that were signed in late-2017, AMF will assemble 50 Block 3 JF-17s and 26 JF-17Bs. Next year Air Engineering Depot 102 at PAF Base Faisal will start overhauling the jet's Klimov RD93 powerplant.

There is a lot going on to occupy the minds of the PAF leadership, and operationally the JF-17 is playing a major part in the defense of Pakistan’s skies, with six operational squadrons. During the PAF’s recent confrontation with the Indian Air Force, known in Pakistan as Operation Swift Retort, PAF Chief of the Air Staff Air Chief Marshal Mujahid Anwar Khan told AIN in mid-April, “The aircraft performed very well against the IAF Mirage 2000s and their Mica missiles, as well as the MiG-21 Bison and its R-73 Archer AAMs.”

On the export front, Aviation Industry Corporation of China (AVIC) has delivered six JF-17s (four single-seaters and two dual seaters) to the Myanmar Air Force, while PAC has sold three examples to Nigeria, and these should be delivered after the pilots are trained in Pakistan. Sales and marketing of the jet were split between PAC and China National Aero-Technology Import & Export Corporation (CATIC) in 2015. CATIC is engaged in discussions with Egypt surrounding the Block 3s, while PAC continues to talk to Malaysia.



Production Line
More than 100 JF-17s have now come off the AMF assembly line, where the wings, horizontal tail, vertical tail, and forward fuselage, representing 58 percent of the fighter, are built. They are matched with the remaining 42 percent built in Chengdu in China, including the mid- and rear- fuselages that are airfreighted to PAC Kamra. The three fuselage sections are mated at the JF-17 subassembly line and are pushed through on a large trolley to one of the four docks in the final assembly facility.

That’s when the avionics, wiring, undercarriage, harnesses, and Klimov RD93 powerplant are added, while the Martin-Baker Mk16 ejection seat comes later. The aircraft’s air-to-air refueling probes are not necessarily fitted on the assembly line, although all the necessary plumbing has been put in place since the production of Block 2 13-129.

After being towed down to the flight test shed, the newly built JF-17s are put through five functional check flights (FCFs) by one of the four qualified test pilots based at the co-located Test and Evaluation Squadron (TES). Three PAF pilots have qualified at the Boscombe Down-based Empire Test Pilot School for the JF-17, but now most of them go to Xian in China to get their qualifications. When the author met Squadron Leader Ali in April, he was about to test-fly the latest JF-17 to leave the assembly line. He went through a six months training program in China after flying with two operational JF-17 squadrons. Working alongside him in the flight test shed was Boscombe-qualified Group Captain Imran, who spent two years during the early days of the JF-17 test program at Chengdu flying the prototypes and was more recently the first JF-17 Combat Commanders School (CCS) commanding officer. He told AIN, “During the FCFs we push the aircraft to the limit, right through the complete envelope, to assess the handling qualities, checking the systems and aircraft performance.”

Once the FCFs are completed the PAF then puts the JF-17 through a further check flight and if there are no snags, the aircraft will be officially handed over.

PAC chairman Air Marshall Ahmer Shahzad told AIN, “Production of subassemblies has already started for the first two 50 Block 3 aircraft, to be assembled next year, and will be followed by another 12 in 2021, 2022, 2023, and 2024. We will assemble eight dual-seaters this year, followed by 14 in 2020, and the remaining four in 2021.”

Building the JF-17 since 2009 has catapulted PAC into the serious business of fighter production, a feat that not many countries can boast, particularly in Asia. The chairman said he is keen to build on this. The company has already built a high-speed aerial target and is close to the completion of an indigenous UAV.

Having flown around 100 hours of test and evaluation sorties, the first JF-17B to be delivered to Pakistan was having an air-to-air refuelling system fitted in mid-April.


Block 3 Jets
The JF-17 Block 3 enhancements will involve new avionics, including a helmet-mounted display and a holographic wide-angle head-up display, better electronic warfare systems with integrated self-protection kit, as well as a missile approach and warning system, an increased payload, and more sophisticated weapons like a fifth-generation short-range air-to-air missile. It will be the ultimate JF-17, and with an AESA radar will have the capability to employ longer-range weapons and track multiple aircraft.

A decision on a new AESA radar for the Block 3s is expected to be made by the end of the year. There are now three Chinese contenders, which were all shown at last year’s Zhuhai Air Show, while Leonardo’s Grifo-E is still on the table.

Nanjing Research Institute of Electronics Technology's KLJ-7A is being marketed by China Electronics Technology Group Corporation in air- and liquid-cooling options. The second contender, which was displayed at the Zhuhai Air Show last November along with the two Nanjing examples, comes from Leihua Electronic Technology Research Institute (LETRI), another air-cooling AESA known as the LKF601E. AVIC has thrown its weight behind this option and claims it was the first air-cooling radar. Replacing the JF-17’s original KLJ-7 is simply a case of taking out the old system and inserting the new one. The PAF’s Flight Test Group is currently working the options.

Weapons Options
The PAF’s JF-17s are operational with the SD-10 beyond visual range air-to-air missile (AAM) with a data link and initial mid-course guidance, PL-5EII infrared short-range AAM, C-802 anti-shipping missile, and a stand-off capability courtesy of its Indigenous Range Extension Kit integrated with the Mk80 series of general-purpose bombs. The PAF chief of air staff recently told AIN that the JF-17 is better than many contemporary aircraft in three areas but would not provide any more details, although the air-to-sea mode is undoubtedly one of them.

02_jf-17jpg.jpg

A large number of weapons that could be integrated on to the JF-17 by customers, were on view at Zhuhai Air show last November.


At IDEF 19, held in Istanbul in early May, an Aselsan source confirmed that deliveries of the first of 50 Aselsan targeting pods for the JF-17s will commence "within a few months," which will provide the JF-17 with a laser-designator capability, working with JTACs on the ground in the air-to-land integration role.

Air Commodore Rashid Habib, JF-17 deputy chief project director, told the audience at the IDEAS 18 Air Power Conference in Karachi, that the JF-17 had flown 40,000 operational hours. He added that the JF-17B would be fitted with a missionized rear cockpit for combat training and operations, a three-axis fly-by-wire kit, and a fifth-generation advanced short-range air-to-air missile.

Why India Shouldn’t Underestimate the Pakistani Air Force’s JF-17 Thunder

March-2nd-2019

Pakistani Air Force JF-17 Thunder Single Engine Light Fighter



The Pakistani Air Force’s JF-17 Thunder single engine light fighter played a key role in clashes with the Indian Air Force in late February 2019, and were responsible for both of the service’s claimed air to air kills against Indian aircraft. The Pakistani military currently deploys two major variants of the fighter, the Block I variant which entered service from 2007 and the Block II variant which entered production in 2013. Approximately 25 Block II variants of the JF-17 are currently being manufactured in Pakistan annually, with plans to terminate production in favour of the upcoming JF-17 Block III in the early 2020s. A twin seat variant of the Block II fighter, the JF-17B, entered service in December 2017. Single engine variants, however, compromise the vast majority of the fleet at present.

JF-17B Twin Seat Fighter




Much like the Indian MIG-21 Bison, an upgraded variant of the venerated design which according to Indian reports was highly successful against a Pakistani F-16 - likely due to its high end avionics, electronic warfare, jamming and missile systems which are all of the fourth generation, the JF-17 has long been underestimated for a number of reasons. The airframe is loosely based on that of the MiG-21 - an evolution of the Chinese J-7 design - but is considerably more capable than that of any other variant or derivative. The fighter’s engines produce little over half the thrust of the Indian Air Force’s MiG-29 - one third that of the elite Su-30MKI - giving it an inferior thrust/weight ratio when fully armed. These are compensated for by a number of factors, including its access to state of the art sensors and munitions - including the Chinese PL-12 long range air to air missile - an analogue to the American AIM-120C - and the YJ-12 anti ship cruise missile. The latter makes the aircraft a potentially highly lethal ship hunter, in some ways comparable to India's Brahmos cruise missile, and its deployment is an effective asymmetric asset against the large Indian surface fleet.

JF-17 with YJ-12 Anti Ship Cruise Missiles




The JF-17 is relatively simple both to operate and maintain, far moreso that the F-16 or MiG-29, and the costs of doing so are also extremely low. The while the aircraft is slower and less manoeuvrable than the F-16, it compensates with a higher altitude and arguably far superior options for its weapons loadout. Block II variants deploy data links and high end electronic capabilities which early F-16 and MiG-29 variants both lacked, while their avionics are also considerably more sophisticated. The fighters’ NRIET KLJ-7 X band fire control radars are also highly capable - variants of the Chengdu J-10’s formidable KLJ-10 - and are capable of tracking up to ten targets at ranges of over 105km. Data links allow the aircraft to potentially make use of longer ranged munitions, particularly when operating alongside AWACS platforms capable of guiding missiles beyond the range of the fighters’ onboard radars. As a key strength of the JF-17 is its compatibility with high end Chinese munitions, it is highly possible that Block II variants could in future receive longer range munitions which would benefit from such guidance - with more advanced variants of the PL-12 reportedly also planned for deployment by the upcoming JF-17 Block III.

Ultimately the JF-17 remains a highly capable fourth generation fighter - more than a match for India’s MiG-21 and Mirage 2000 single engine light fighters and potentially capable of posing a threat to medium weight platforms such as the MiG-29 and Rafale - though likely still struggling against the Su-30MKI. The design is set to be enhanced considerably in the near future with the induction of the Block III variant, which will reportedly deploy a new radar, an infra red search and tracking system (IRST), helmet mounted display, new electronic warfare and jamming systems, and potentially even PL-15 air to air missiles - which considerably outrange anything currently in the Indian arsenal.

Keeping PAF Mirages flying
Published in Show Daily 2018 - Day 2

December 20, 2018

Inside the Mirage Overhaul Wing. Around ten Mirages are worked on at a time.





Operating a fleet of around 100 1960s-era Dassault Mirages III/Vs means the Pakistan Air Force (PAF) is challenged to keep them airworthy. Fortunately, in 1978, just a decade after buying its initial batch of 24 Mirage IIIEP, DP and RPs the PAF leadership had set up its Mirage Rebuild Factory.


Today, the facility has worked on 350Mirages and 2,280 ATAR 09C engines which power the French delta-winged jet. In addition, there has been the recovery of 19 structurally damaged aircraft, upgrade of 36 retired ex-Royal Australian Air Force (RAAF) Mirage IIIs to the Retrofit of Strike Element (ROSE1) version and modernisation of 14 Mirage VEFs with the ROSE III. When the aircraft were more recently modernised with air-to-air refuelling systems, it was the MRF which integrated the Mirage Pressurised Refuelling (MPR) into the jets.

Right from the outset, the PAF wanted to overhaul its Mirage fleet in Pakistan. Sending them back to France was costly and lengthy too – with the aircraft being out of service for 18 months. Time, it could not afford while tension with its old foe, India existed.

Work to set up the factory Initially known as Project-741, was given the green light in March 1974. All 24 Mirage IIIEP, DP and RPs purchased in1967 would require an overhaul in 1975, approximately nine years after their manufacture. By then 28 brand new Mirage VPAs had also been delivered and the plan was to overhaul all the Mirage IIIs by 1978, then the Mirage Vs. Facilities to work on the ‘Delta’, their components and ATAR 09C engines were put in place. On May 3, 1978 the first Mirage IIIEP, 67-101(later named ‘Old Baba’) was flown to Pakistan Aeronautical Complex (PAC) Kamra, by Wing Commander Saeed Anwar, who ironically went on to become the PAC Kamra director general from 1997 to 1999. Eleven days after the jet arrived, on May 14the MRF was inaugurated within the new factory, commanded by Air Commodore Atta Illahi Sheikh.

On 11 December 1979, 67-101 made its first flight after overhaul and handed back to the PAF on 20 February 1980. A large ceremony that day, saw the President of Pakistan, the late General Muhammad Zia-ul-Haq thank all those concerned for their tireless work in setting up the rebuild factory within such a short time. By 1987, all the original PAF Mirages had been overhauled.

Aircraft accidents, eventually led to a Fuselage Structural Repair Facility being built. After Mirage V 70-415 was involved in an accident, Dassault was approached for a damage assessment and then repair of the jet. A fuselage repair jig was subsequently ordered which in May 1989, was installed in the original production hangar built in 1978, that was standing idle. The high cost of repairing one of these aircraft abroad coupled with a long lead in time, saw the Structures Wing repairing aircraft within months. To date, 19 PAF Mirages – a squadron strength, has been recovered at a minimal cost.

In 1980, a Wing Refurbishing Facility was set up from equipment acquired from Australia under Blue Flash V programme and was soon joined by a ‘lifting and turning jig’ and a wing repair jig. The investment made in this equipment in the 1990s has led to millions of dollars of savings being made over the intervening years. One of the major issues with the Mirage these days is the wings, but this department is helping to combat that issue.

The WRF has repaired 19 Mirages over the years, and has helped to increase the Mirage fleet Right now, the PAF is facing problems of cracked ribs in the wings so the WRF is replacing any damaged structures. The wings are regularly monitored with x-rays, and if required personnel open the wings to replace the cracked ribs then close them to provide a new life.
