leading edge root extensions (LERX). The vertical tail fin was enlarged to house an expanded
electronic warfare equipment bay in the tip.
[18][41][42] The redesigned aircraft had a slightly increased maximum take-off weight and incorporated an increased quantity of Chinese-sourced avionics; however PAF had selected Western avionics for their aircraft, postponing PAF deliveries from late 2005 until 2007. Pakistan evaluated British, French, and Italian avionics suites, the winner of which was expected to be finalised in 2006.
[43] PT-04, the fourth prototype and the first to incorporate the design changes, was rolled out in April 2006 and made its first flight on 28 April 2006.

The modified air intakes replaced conventional intake ramps—whose function is to divert turbulent boundary layer airflow away from the inlet and prevent it entering the engine—with a diverterless supersonic inlet (DSI) design.[41] The DSI uses a combination of forward-swept inlet cowls and a three-dimensional compression surface to divert the boundary layer airflow at high sub-sonic and supersonic speeds. According to Lockheed Martin, the DSI design prevents most of the boundary layer air from entering the engine at speeds up to two times the speed of sound, reduces weight by removing the need for complex mechanical intake mechanisms,[45] and is boundary layer airflow away from the inlet and prevent it entering the engine—with a diverterless supersonic inlet (DSI) design.[41] The DSI uses a combination of forward-swept inlet cowls and a three-dimensional compression surface to divert the boundary layer airflow at high sub-sonic and supersonic speeds. According to Lockheed Martin, the DSI design prevents most of the boundary layer air from entering the engine at speeds up to two times the speed of sound, reduces weight by removing the need for complex mechanical intake mechanisms,[45] and is stealthier than a conventional intake.[41] In 1999, developmental work on the DSI with the aim of improving aircraft performance commenced. The JF-17 design was finalised in 2001.[46] Multiple models underwent wind tunnel tests; it was found that the DSI reduced weight, cost, and complexity while improving performance.[45]
For the avionics and weapons qualification phase of the flight testing, PT-04 was fitted with a fourth-generation avionics suite that incorporates sensor fusion, an electronic warfare suite, enhanced man-machine interface, Digital Electronic Engine Control (DEEC) for the RD-93 turbofan engine, FBW flight controls, day/night precision surface attack capability, and multi-mode, pulse-Doppler radar for BVR air-to-air attack capability.[47] The sixth prototype, PT-06, made its maiden flight on 10 September 2006.[48] Following a competition in 2008, Martin-Baker was selected over a Chinese firm for the supply of fifty PK16LE ejection seats.[49]
On 2 March 2007, the first consignment of two small-batch-production (SBP) aircraft arrived in a dismantled state in Pakistan. They flew for the first time on 10 March 2007 and took part in a public aerial demonstration during a Pakistan Day parade on 23 March 2007. The PAF intended to induct 200 JF-17 by 2015 to replace all its Chengdu F-7, Nanchang A-5, and Dassault Mirage III/5 aircraft. In preparation for the in-flight refuelling of JF-17s, the PAF has upgraded several Mirage IIIs with IFR probes for training purposes.[50] A dual-seat, combat-capable trainer was originally scheduled to begin flight testing in 2006;[20] in 2009 Pakistan reportedly decided to develop the training model into a specialised attack variant.[51][52]
In November 2007, the PAF and PAC conducted flight evaluations of aircraft fitted with a variant of the NRIET KLJ-10 radar developed by China's Nanjing Research Institute for Electronic Technology (NRIET), and the LETRI SD-10 active radar homing AAM.[53] In 2005, PAC began manufacturing JF-17 components; production of sub-assemblies commenced on 22 January 2008.[54][55] The PAF was to receive a further six pre-production aircraft in 2005, for a total of 8 out of an initial production run of 16 aircraft.

Initial operating capability was to be achieved by the end of 2008.[56] Final assembly of the JF-17 in Pakistan began on 30 June 2009; PAC expected to complete production of four to six aircraft that year. They planned to produce twelve aircraft in 2010 and fifteen to sixteen aircraft per year from 2011; this could increase to twenty-five aircraft per year.[57] On 29 December 2015, Pakistan Aeronautical Complex (PAC) announced the rollout of the 16th JF-17 Thunder fighter manufactured in the calendar year 2015, taking total number of manufactured aircraft to more than 66. Later, a PAF spokesperson said that in light of the interest shown by various countries, it has been decided that production capacity of JF-17 Thunder at PAC Kamra will be expanded.[6]
Russia signed an agreement in August 2007 for re-export of 150 RD-93 engines from China to Pakistan for the JF-17.[58] In 2008, the PAF reported it was not fully satisfied with the RD-93 engine and that it would only power the first 50 aircraft; it was alleged that arrangements for a new engine, reportedly the Snecma M53-P2, may have been made.[59] Mikhail Pogosyan, head of the MiG and Sukhoi design bureaus, recommended the Russian defence export agency Rosoboronexport block RD-93 engine sales to China to prevent export competition from the JF-17 against the MiG-29.[60][61] At the 2010 Farnborough Airshow, the JF-17 was displayed internationally for the first time; aerial displays at the show were intended but were cancelled due to a late attendance decision as well as license and insurance costs.[62] According to a Rosoboronexport official at the Airshow China 2010, held on 16–21 November 2005 in Zhuhai, China, Russia and China had signed a contract worth $238 million for 100 RD-93 engines with options for another 400 engines developed for the FC-1.[63]
According to media reports, Pakistan planned to increase production of JF-17s by 25% in 2016.[64]
Pakistan negotiated with British and Italian defence firms regarding avionics and radars for the JF-17 development. Radar options include the Italian Galileo Avionica's Grifo S7,[65] the French Thomson-CSF's RC400 (a variant of the RDY-2),[66] and the British company SELEX Galileo's Vixen 500E active electronically scanned array (AESA) radar.[19] In 2010, the PAF had reportedly selected ATE Aerospace Group to integrate French-built avionics and weapons systems over rival bids from Astrac, Finmeccanica and a Thales-Sagem joint venture. Fifty JF-17s were to be upgraded and an optional fifty from 2013 onwards, at a cost of up to US$1.36 billion. The RC-400 radar, MICA AAMs, and several air-to-surface weapons are believed to be in the contract. The PAF also held talks with South Africa for the supply of Denel A-darter AAMs.[67][68]
In April 2010, after eighteen months of negotiations, the deal was reportedly suspended; reports cited French concerns about Pakistan's financial situation, the protection of sensitive French technology, and by Indian lobbying, which operates many French-built aircraft.[69][70] France wanted the PAF to purchase several Mirage 2000-9 fighters from the United Arab Emirates Air Force, which would overlap with the upgraded JF-17.[71] In July 2010, the PAF's Chief of Air Staff, Air Chief Marshal Rao Qamar Suleman, said such reports were false, stating: "I have had discussions with French Government officials who have assured m

On 18 December 2013, production of Block 2 JF-17s began at PAC's Kamra facility.[73] These have an air-to-air refuelling capability, improved avionics, enhanced load carrying capacity, data link, and electronic warfare capabilities.[74] Block 2 construction is planned to run until 2016, after which the manufacturing of further developed Block III aircraft is planned.[75] In December 2015, it was announced that the 16th Block II aircraft had been handed over resulting in standing up of the 4th squadron.[76]
On 17 June 2015, Jane's Defence Weekly confirmed[77] that JF-17 Block III will have an AESA radar, a helmet-mounted display (HMD) and possibly an internal infrared search and tracking (IRST) system.[78] A two-seat version was also reportedly be produced in Block III.[79] Unconfirmed reports claim that Block III will also have a better flight management system.[80] Selex ES has promoted its next-generation cockpit as a possible upgrade of JF-17 Block III; this cockpit includes a new mission computer, an enhanced head-up display and contemporary multi-function displays, plus the capability for the pilot to use a single, large-area display instead.[81]
The air frame is of semi-monocoque structure constructed primarily of aluminum alloys. High strength steel and titanium alloys are partially adopted in some critical areas. The air frame is designed for a service life of 4,000 flight hours or 25 years, the first overhaul being due at 1,200 flight hours.[20] Block 2 JF-17s incorporate greater use of composite materials in the air frame to reduce weight.[82] The retractable undercarriage has a tricycle arrangement with a single steerable nose-wheel and two main undercarriages. The hydraulic brakes have an automatic anti-skid system. The position and shape of the inlets is designed to give the required airflow to the jet engine during maneuvers involving high angles of attack.[20]
The mid-mounted wings are of cropped-delta configuration. Near the wing root are the LERX, which generate a vortex that provides extra lift to the wing at high angles of attack encountered during combat maneuvers. A conventional tri-plane empennage arrangement is incorporated, with all-moving stabilators, single vertical stabiliser, rudder, and twin ventral fins. The flight control system (FCS) comprises conventional controls with stability augmentation in the yaw and roll axis and a digital fly-by-wire (FBW) system in the pitch axis. The leading-edge slats/flaps and Trailing edge flaps are automatically adjusted during manoeuvring to increase turning performance.cropped-delta configuration.

The leading-edge slats/flaps and Trailing edge flaps are automatically adjusted during manoeuvring to increase turning performance.[20] The FCS of serial production aircraft reportedly have a digital quadruplex (quad-redundant) FBW system in the pitch axis and a duplex (dual-redundant) FBW system in the roll and yaw axis.[48]
The glass cockpit is covered by a transparent, acrylic canopy that provides the pilot with a good, all-round field of view. It has three large Multifunction Colour Displays (MFD) and smart Heads-Up Display (HUD) with built-in symbol generation capability. A centre stick is used for pitch and roll control while rudder pedals control yaw. A throttle is located to the left of the pilot. The cockpit incorporates hands-on-throttle-and-stick (HOTAS) controls. The pilot sits on a Martin-Baker Mk-16LE zero-zero ejection seat. The cockpit incorporates an electronic flight instrument system (EFIS) and a wide-angle, holographic head-up display (HUD), which has a minimum total field of view of 25 degrees. The EFIS comprises three colour multi-function displays, providing basic flight information, tactical information, and information on the engine, fuel, electrical, hydraulics, flight control, and environment control systems. The HUD and MFD can be configured to show any available information. Each MFD is 20.3 cm (8.0 in) wide and 30.5 cm (12.0 in) tall and is arranged side by side in portrait orientation. The central MFD is placed lowest to accommodate a control panel between it and the HUD.[20]
Up to 3,629 kg (8,001 lb) of ordnance, equipment, and fuel can be mounted under the hardpoints, two of which are on the wing-tips, four are under the wings and one is under the fuselage.[20]
The avionics software incorporates the concept of open architecture. Instead of the military-optimised Ada programming language, the software is written using the popular C++ programming language, enabling the use of the numerous civilian programmers available.[83] The aircraft also includes a health and usage monitoring system, and automatic test equipment.[20][84]
The JF-17 has a defensive aids system (DAS) composed of various integrated sub-systems. A radar warning receiver (RWR) provides data such as direction and proximity of enemy radars, and an electronic warfare (EW) suite housed in a fairing at the tip of the tail fin interferes with enemy radars. The EW suite is also linked to a Missile Approach Warning (MAW) system to defend against radar-guided missiles. The MAW system uses several optical sensors across the airframe to detect the rocket motors of missiles across a 360-degree coverage.[19] Data from the MAW system, such as direction of inbound missiles and the time to impact, is shown on cockpit displays and the HUD. A countermeasures dispensing system releases decoy flares and chaff to help evade hostile radar and missiles. The DAS systems will also be enhanced by integration of a self-protection radar-jamming pod that will be carried externally on a hardpoint.[20]
The first forty-two PAF production aircraft are equipped with the NRIET KLJ-7 radar,[85][86] a variant of the KLJ-10 radar developed by China's Nanjing Research Institute of Electronic Technology (NRIET) and also used on the Chengdu J-10. Multiple modes can manage the surveillance and engagement of up to forty air, ground, and sea targets; the track-while-scan mode can track up to ten targets at BVR and can engage two simultaneously with radar-homing AAMs. The operation range for targets with a radar cross-section (RCS) of 5 m2 (54 sq ft) is stated to be ≥ 105 km (65 mi) in look-up mode and ≥ 85 km (53 mi) in look-down mode.[86][87] A forward looking infrared (FLIR) pod for low-level navigation and infra-red search and track (IRST) system for passive targeting can also be integrated;[20] the JF-17 Block 2 is believed to incorporate an IRST.[82] In April 2016, Air Marshal Muhammad Ashfaque Arain said that, "JF-17 needs a targeting pod, as the jets' usefulness in current operations was limited due to lack of precision targeting. To fulfill this gap the Air Force was interested in buying the Thales-made Damocles, a third-generation targeting pod; which was a priority."[88] In 2017, Aselsans ASELPOD was tested and successfully integrated with the JF-17 and Pakistan has subsequently purchased at least eight targeting pods from Aselsan.[89] This integration has significantly enhanced the JF-17 platform's ability to launch precision strikes.
A helmet-mounted sight (HMS) developed by Luoyang Electro-Optics Technology Development Centre of AVIC was developed in parallel with the JF-17; it was first tested on Prototype 04 in 2006.[90][91] It was dubbed as EO HMS, (Electro-Optical Helmet Mounted Sight) and was first revealed to the public in 2008 at the 7th Zhuhai Airshow, where a partial mock-up was on display.[citation needed] The HMS tracks the pilot's head and eye movements to guide missiles towards the pilot's visual target.[19] An externally carried day/night laser designator targeting pod may be integrated with the avionics to guide laser-guided bombs (LGBs).[20] An extra hardpoint may be added under the starboard air intake, opposite the cannon, for such pods. To reduce the numbers of targeting pods required, the aircraft's tactical data link can transmit target data to other aircraft not equipped with targeting pods.[19] The communication systems comprise two VHF/UHF radios; the VHF radio has the capacity for data linking for communication with ground control centers, airborne early warning and control aircraft and combat aircraft with compatible data links for network-centric warfare, and improved situation awareness.[92] The aircraft uses RLGs along with GPS for navigation. The aircraft is equipped with an IFF Transponder which allows it to differentiate between friendly aircraft and enemy aircraft. The ACMI aids in aerial combat for maneuvering.[93]
The first two blocks of JF-17 is powered by a single Russian RD-93 turbofan engine, which is a variant of the Klimov RD-33 engine used on the MiG-29 fighter. The engine gives more thrust and significantly lower specific fuel consumption than turbojet engines fitted to older combat aircraft being replaced by the JF-17. The advantages of using a single engine are a reduction in maintenance time and cost when compared to twin-engined fighters. A thrust-to-weight ratio of 0.99 can be achieved with full internal fuel tanks and no external payload. The engine's air supply is provided by two bifurcated air inlets (see airframe section).[94]
The RD-93 is known to produce smoke trails.[94] The Guizhou Aero Engine Group has been developing a new turbofan engine, the WS-13 Taishan, since 2000 to replace the RD-93. It is based on the RD-33 and incorporates new technologies to boost performance and reliability. A thrust output of 80 to 86.36 kN (17,980 to 19,410 lbf), a lifespan of 2,200 hours, and a thrust-to-weight ratio of 8.7 are expected. An improved version of the WS-13, developing a thrust of around 100 kN (22,000 lbf) (22,450 lb), is also reportedly under development.[95] During the 2015 Paris Air Show, it was announced that flight testing of a JF-17 equipped with the WS-13 engine had begun.[96] In 2015, a representative of Pakistan Aeronautical Complex said that Pakistan would continue to use the RD-93 engine on their fighters.[97] Local media reports in January 2016 said that Russia was planning to sell engines for JF-17 directly to Pakistan.[98] According to a PAC representative, Pakistan is looking to collaborate with Russia in developing and repairing engines.[99]
The fuel system comprises internal fuel tanks located in the wings and fuselage with a capacity of 2,330 kg (5,140 lb); they are refuelled through a single point pressure refuelling system (see turbine fuel systems). Internal fuel storage can be supplemented by external fuel tanks. One 800-litre (180 imp gal) drop tank can be mounted on the aircraft's centerline hard point under the fuselage and two 800-litre or 1,110-litre (240 imp gal) drop tanks can be mounted on the two inboard under-wing hardpoints.[20] The fuel system is compatible with in-flight refueling (IFR), allowing tanker aircraft to refuel inflight, and increasing its range and loitering time significantly. All production aircraft for the PAF are to be fitted with IFR probes.[19] In June 2013, PAF Air Chief Marshal Tahir Rafique Butt said ground tests on the JF-17's refueling probes had been successfully completed and the first mid-air refuelling operations would commence that summer.[100]
The JF-17 can be armed with up to 4,325 kg (9,535 lb) of air-to-air and air-to-ground weaponry, and other equipment mounted externally on the aircraft's seven hardpoints.[20] One hardpoint is located under the fuselage between the main landing gear, two are underneath each wing, and one is at each wing-tip. All seven hardpoints communicate via a MIL-STD-1760 data-bus architecture with the Stores Management System,[20] which is stated to be capable of integration with weaponry of any origin.[66] Internal armament comprises one 23 mm (0.91 in) GSh-23-2 twin-barrel cannon mounted under the port side air intake, which can be replaced with a 30 mm (1.2 in) GSh-30-2 twin-barrel cannon.[18][101]
The wing-tip hard-points are typically occupied by short range infra-red homing AAMs. Many combinations of ordnance and equipment such as targeting pods can be carried on the under-wing and under-fuselage hard-points. Underwing hard-points can be fitted with multiple ejector racks, allowing each hard-point to carry two 500 lb (230 kg) unguided bombs or LGBs—Mk.82 or GBU-12. It is unknown whether multiple ejector racks can be used for ordnance such as beyond visual range (BVR) AAMs.[19] Active radar homing BVR AAMs can be integrated with the radar and data-link for mid-course updates. The Chinese PL-12/SD-10 is expected to be the aircraft's primary BVR air-to-air weapon, although this may change if radars of other origin are fitted. Short range, infra-red homing missiles include the Chinese PL-5E and PL-9C. The PAF is also seeking to arm the JF-17 with a fifth generation close-combat missile such as the PL10E IRIS-T or A-Darter. These will be integrated with the HMS/D and the radar for targeting.[19][20]

Unguided air-to-ground weaponry includes rocket pods, gravity bombs and Matra Durandal anti-runway munitions. Precision-guided munitions such as LGBs and satellite-guided bombs are also compatible with the JF-17, as are other guided weapons such as anti-ship missiles and anti-radiation missiles.[20] Pakistan planned to bring the Brazilian MAR-1 anti-radiation missile into service on its JF-17 fleet in 2014.[102]
Small batch production of the single-seat, single-engine JF-17s began in China in June 2006. The first two small-batch-produced aircraft were delivered on 2 March 2007 and first flew in Pakistan on 10 March.[103] They took part in an aerial display on 23 March 2007 as part of the Pakistan Day Joint Services Parade in Islamabad.[104][105] Another six small-batch-produced aircraft were delivered by March 2008.[106] These were extensively flight-tested and evaluated by the PAF.[107] Two serial production aircraft were delivered from China in 2009 and the first Pakistani-manufactured aircraft was delivered to the PAF in a ceremony on 23 November 2009.[108]
On 18 February 2010, the first JF-17 squadron, No. 26 Black Spiders, was officially inducted into the PAF with an initial strength of 14 fighter planes.[109][110] These aircraft first saw service in the anti-terrorist operation in South Waziristan, during which various types of weapons were evaluated.[111] They took part in the PAF's High Mark 2010 exercise from 29 April, where they were used by the Blue Force to attack Red Land surface targets with precision air-to-surface weapons.[112][113 On 18 February 2010, the first JF-17 squadron, No. 26 Black Spiders, was officially inducted into the PAF with an initial strength of 14 fighter planes.[109][110] These aircraft first saw service in the anti-terrorist operation in South Waziristan, during which various types of weapons were evaluated.[111] They took part in the PAF's High Mark 2010 exercise from 29 April, where they were used by the Blue Force to attack Red Land surface targets with precision air-to-surface weapons.[112][113] A re-equipment ceremony for No. 26 Black Spiders Squadron took place on 11 April 2011, during which it was stated that the JF-17 had "revolutionized the PAF's operational concepts". The then Chief of the Air Staff, Air Chief Marshal Rao Qamar Suleman said: "Today as we re-equip No 26 squadron, we have also raised No. 16 Squadron with the JF-17 Thunder aircraft. I would like to mention and appreciate the contribution and support of the Chinese in helping us acquire a technological breakthrough in the shape of this aircraft."[114] According to Pakistani forums, No 27 Squadron "Zarrars" replaced its Mirage 5EF with JF-17 in 2013.[115] No 2 Squadron currently tasked with sea strikes reequipped with JF-17s in Sept 2015 replacing the F7s.[116] No 16 Squadron "Black Panthers" has also been equipped with the JF-17.[117] The next squadron is supposed to be No 7 Squadron.[118]
On 19 June 2017, it was reported that a JF-17 shot down an Iranian UAV operating in Pakistan's Pangjur District.[119]
On 27 February 2019, during the tense standoff between India and Pakistan, Pakistan claimed that its JF-17s had shot down two Indian aircraft: a MiG-21 and a Su-30MKI, operating in Pakistan's airspace over the disputed region of Kashmir.[120][121] India, on the other hand, claimed to have shot down a Pakistani F-16, while losing a MiG-21 in the aerial engagement.[122] India denied the loss of any Su-30MKI and stated that all aircraft returned safely, whereas Pakistan denied the use or loss of any F-16 during the stand-off.[123][124]
In December 2014, during the International Defence Exhibition and Seminar in Karachi, Nigeria was reportedly buying between 25 and 40 JF-17s from Pakistan. Nigerian Air Force chief Air Marshal Adesola Nunayon Amosu had visited Pakistan earlier in October 2014.[125] Nigeria became the second customer in 2016 by placing an order for 3 planes. However, as the news reports value the deal at US$25 million, it is not clear if the item is misreported.[126][127] A June 2016 article in Jane's re-affirmed NAF budget for 3 JF-17, 10 Super Mushshak, and 2 Mi-35M aircraft in 2016.[128] According to Indian media, a deal to buy JF-17s might be signed in November with a MoU already signed.[129]
The Nigerian Air Force has confirmedThe Nigerian Air Force has confirmed[130] it is expecting delivery of JF-17 for use in military operations against Jihadi militants in Northern Nigeria.
In October 2018 Pakistan approved of the sale and local Nigerian production of three JF-17s for US$184.3 million. The aircraft are rumored to be of a later version than the initially agreed sale, providing more advanced systems.[131][132]
In July 2015, Myanmar ordered 16 JF-17 Thunder Fighter jets from Pakistan and China. Unlike the engines of Pakistani JF-17 Block I and Block II, Myanmar Air Force's JF-17s are using russian RD-33 engines. In late 2015, Myanmar ordered 16 RD-33 engines from Russia which were received in 2018 and 2019.[133] On 17 December 2018, Jane's disclosed that the Myanmar Air Force had received the first of up to 16 JF-17s it had ordered in 2015.[134] An official Myanmar Air Force video released on Air Force day showcased a number of JF-17s, both on static display and in the air.[135]
Accidents
Since its introduction, there have been several accidents involving the JF-17.
The Azerbaijani Air Forces negotiated with China for several dozen JF-17s worth approximately US$16 to 18 million each.[157] The Sudanese Air Force was reportedly negotiating to buy twelve aircraft.[158] The Air Force of Zimbabwe reportedly planned to purchase twelve JF-17s in 2004, as part of a $240 million deal with China. No such sales have materialized.[159][160] In 2010, China was reportedly in talks about the JF-17 with five or six countries, some of which had sent pilots to China to undergo test flights.[161]
Argentine officials at the 2013 Paris Air Show said they had discussed JF-17 co-production with Chinese officials, calling it the first formal effort potentially leading to the co-production of a modern Chinese fighter in Latin America. Fábrica Argentina de Aviones (FAdeA) officials said the co-produced FC-1 could be called the "Pulqui-III", recalling FAdeA's Pulqui-II, Latin America's first swept wing jet fighter.[162] On 15 February 2015, after a three-day visit to Beijing by Argentine president Cristina Fernández de Kirchner, Argentina completed negotiations to purchase twenty FC-1s from Chengdu Aircraft Corporation.[163]
In January 2014, the Royal Saudi Air Force was reportedly examining potential technology transfer and co-production opportunities for the JF-17. Saudi Defence Minister Prince Salman bin Sultan toured the JF-17 project during a visit to Pakistan.[164][165]
In June 2015, Pakistani media suggested that an export order had been confirmed with the Sri Lanka Air Force; claims were made that the JF-17's first sales contract had been signed with the Sri Lanka Air Force at the 51st Paris Air Show.The Azerbaijani Air Forces negotiated with China for several dozen JF-17s worth approximately US$16 to 18 million each.[157] The Sudanese Air Force was reportedly negotiating to buy twelve aircraft.[158] The Air Force of Zimbabwe reportedly planned to purchase twelve JF-17s in 2004, as part of a $240 million deal with China.

In January 2014, the Royal Saudi Air Force was reportedly examining potential technology transfer and co-production opportunities for the JF-17. Saudi Defence Minister Prince Salman bin Sultan toured the JF-17 project during a visit to Pakistan.[164][165]
In June 2015, Pakistani media suggested that an export order had been confirmed with the Sri Lanka Air Force; claims were made that the JF-17's first sales contract had been signed with the Sri Lanka Air Force at the 51st Paris Air Show.[166][167] Other sources claimed that Myanmar is the first buyer of Pakistani JF-17s.[168] Reportedly, the order would cover around 18–24 aircraft and deliveries set to begin in 2017. During a state visit by Nawaz Sharif in January 2016, Sri Lanka reportedly signed an agreement to buy eight JF-17s from Pakistan;[169] however, the Sri Lankan government has issued denials.[170] The alleged deal was said to involve 10–12 aircraft, each valued at US$35 million, for a total of US$400 million[171] Reportedly, any such sale was scuppered by Indian diplomatic pressure.[172][173]
Morocco has shown interest in the JF-17, having invited a sales team to showcase it in the Marrakech Air Show 2016.[174][175] According to a local analyst, a potential acquisition by Morocco may be complicated by incompatible technologies; the JF-17 Block I and Block II have broadly different electronics suites and air-to-air & air-to-surface munitions than its current Western-sourced aircraft, such as the Mirage F-1 (MF2000), F-5E/F Tiger II and Alpha Jet.[176]
Two air frame configurations were tested during the prototype stage. The first configuration was tested on the first three prototype aircraft; PT-01, PT-02, and PT-03. The next three prototypes PT-04, PT-05, and PT-06 were of the second configuration, incorporating modifications such as DSI, wider LERX, extended ventral fins, and a taller, less swept vertical stabilizer with a rectangular fairing at the tip containing electronic warfare equipment and small blister fairings at the base containing Missile Approach Warning sensors. The PT-04 prototype was primarily used for avionics and weapon qualification tests.[177] Prototype-01 first flew in August 2003; Prototype-03 followed in April 2004. On 10 May 2006, Prototype 04 made its maiden flight.[178]

In 2007, a dual-seat version for training and strike roles was proposed and due to the customer interests the development started in 2015.[51] According to the PAF, the JF-17B dual seat fighter jet is currently entering the testing phase.[179]
