The CAC/PAC JF-17 Thunder, also known as the FC-1 Xiaolong, is a fourth-generation, single-engine, lightweight multirole combat aircraft developed through a collaboration between China's Chengdu Aircraft Corporation (CAC) and Pakistan's Pakistan Aeronautical Complex (PAC). It serves as a replacement for the A-5C, F-7P/PG, Mirage III, and Mirage 5 within the Pakistan Air Force (PAF). The JF-17 is designed for multiple roles such as interception, ground attack, anti-ship missions, and reconnaissance tasks. The name "JF-17" stands for "Joint Fighter-17," highlighting its collaborative development and its position as a successor to the F-16. Its Chinese designation, "FC-1," translates to "Fighter China-1."

Equipped to carry a variety of weapons, the JF-17 can deploy air-to-air and air-to-surface missiles, guided and unguided bombs, along with a 23 mm GSh-23-2 twin-barrel autocannon. Its propulsion comes from either a Guizhou WS-13 or a Klimov RD-93 afterburning turbofan engine, enabling speeds up to Mach 1.6. The aircraft complements the Lockheed Martin F-16 fleet in the PAF at approximately half the cost, with the Block II variant costing around $25 million. Since its induction in 2010, it has become a principal fighter within the PAF.

Production responsibilities are divided with Pakistan manufacturing 58%—including the front fuselage, wings, and vertical stabilizer—and China producing 42%, with final assembly conducted in Pakistan. In 2015, Pakistan produced 16 units; by 2016, PAC’s annual output reached 20 aircraft. By April 2017, PAC had delivered 70 Block 1 and 33 Block 2 models to the PAF. By 2016, JF-17s had logged over 19,000 operational flight hours. Development of the dual-seat JF-17B variant began in 2017 to enhance operational capabilities and pilot training; serial production started in 2018 with 26 units delivered by December 2020. Late in 2020, PAC commenced serial production of the advanced Block 3 version featuring AESA radar, an upgraded Klimov RD-93MA engine, enhanced HUD, improved electronic countermeasures, an extra hardpoint, and superior weapons integration.

JF-17s from the PAF have actively participated in various combat operations including anti-terror campaigns in North Waziristan (2014 and 2017), downing an Iranian drone over Balochistan (2017), conducting airstrikes during the 2019 Jammu and Kashmir conflict alongside aerial engagements with India, and Operation Marg Bar Sarmachar (2024) targeting Baloch separatists within Iran’s borders. In March and December of 2024, they executed cross-border strikes against Pakistani Taliban strongholds in Afghanistan. The Nigerian Air Force utilizes JF-17s for counter-terrorism missions while Myanmar’s Air Force employs them against insurgent factions. During the May 2025 India–Pakistan conflict, PAF extensively deployed JF-17s for both air-to-air combat and ground attack roles.

Development

Background

The inception of the JF-17 was driven by Pakistan Air Force’s requirement for an economical yet capable fourth-generation lightweight multirole fighter to replace its aging fleet comprising Nanchang A-5C bombers, Chengdu F-7P/PG interceptors, and Dassault Mirage III/5 fighters. The project’s estimated cost was , equally funded by Pakistan and China. Additionally intended for export markets as an affordable alternative to expensive Western fighters, development was spearheaded by Yang Wei—China’s renowned designer also responsible for the Chengdu J-20.

By 1989, facing US sanctions, Pakistan discontinued Project Sabre II—a joint design venture with Grumman and China—and shifted focus towards redesigning and upgrading the Chengdu F-7 platform. In 1988, China and Grumman collaborated on a nine-month preliminary design study known as Super 7 for upgrading the F-7; however, Grumman withdrew following sanctions imposed after the 1989 Tiananmen Square incident. This led to initiation of the Fighter China project in 1991. Subsequently in 1995, Pakistan and China formalized a memorandum of understanding to jointly design and develop a new fighter aircraft, refining project specifics over subsequent years. Mikoyan joined in June 1995 providing design assistance including secondment of engineers to CAC.

Initiation of the FC-1 Program

By October 1995, Pakistan aimed to finalize the selection of a Western supplier for the FC-1's avionics integration before the year's end, targeting production commencement by 1999. The avionics suite was to encompass radar, an Inertial navigation system, Head-up display, and Multi-function display units. Proposals were received from Thomson-CSF, offering a version of the Radar Doppler Multitarget (RDY); SAGEM, presenting avionics akin to those in the ROSE upgrade project; and Marconi Electronic Systems, which proposed its Blue Hawk radar. FIAR’s (currently SELEX Galileo) Grifo S7 radar gained preference due to its established relationship with the PAF. In February 1998, Pakistan and China formalized a letter of intent concerning airframe development collaboration. Meanwhile, Russia's Klimov offered a variant of the RD-33 turbofan engine for this fighter. In April 1999, South Africa’s Denel suggested equipping the Super 7 with the T-darter BVR air-to-air missile (AAM), intended to replace the previously planned R-Darter. Earlier in 1987, Pratt & Whitney proposed three engine options for the Super-7 project—PW1212, F404, and PW1216—with possibilities for local assembly in China or Pakistan. Plans for Rolls-Royce’s RB199-127/128 turbofan were discontinued in 1989.

In June 1999, a formal agreement was inked to jointly develop and manufacture the Chengdu FC-1/Super 7. Following GEC-Marconi’s withdrawal from the integrated avionics competition, FIAR and Thomson-CSF submitted proposals based on Grifo S7 and RC400 radars respectively, despite earlier intentions to deploy Blue Hawk radar on the PAF’s Super 7. The imposition of sanctions after Pakistan's nuclear tests in 1998 caused an 18-month slowdown in design progress and delayed delivery of Western avionics. In early 2001, the PAF separated airframe development from avionics work to maintain momentum on aircraft design while facilitating easier future avionics integration.

Prototype manufacturing commenced in September 2002, with a full-scale FC-1/Super 7 mock-up showcased at Airshow China in November that year. The initial batch of Klimov RD-93 turbofan engines destined for prototypes arrived in 2002. According to a representative from China National Aero-Technology Import & Export Corporation (CATIC), the JF-17’s affordability is largely due to adapting certain systems from the Chengdu J-10. This transfer of technology—replicating aircraft systems from the J-10 onto the JF-17—significantly reduces costs. Additionally, employing computer-aided design tools expedited the JF-17’s design timeline.

Flight Trials and Aircraft Refinement

The first prototype, designated PT-01, was unveiled on 31 May 2003 and moved to Chengdu Flight Test Centre for its inaugural flight. Although initially scheduled for June, this was postponed due to the SARS epidemic. Around this period, the project’s name shifted from Super-7 to "JF-17" (Joint Fighter-17). Low-speed taxi tests began on 27 June 2003, followed by a maiden flight in late August or officially early September 2003. By March 2004, CAC had completed approximately twenty flights with PT-01. PAF test pilots operated PT-01 on 7 April 2004; subsequently, PT-03 took flight on 9 April. Pakistan intended to induct roughly two hundred units by March of that year.

Post PT-03 testing led to multiple design enhancements. To mitigate excessive exhaust smoke produced by the RD-93 engine, intake ducts were enlarged. Control challenges prompted adjustments to wing leading edge root extensions (LERX), while an enlarged vertical tail fin accommodated expanded electronic warfare systems. This updated configuration featured a modestly increased maximum take-off weight and incorporated more Chinese avionics components; however, PAF opted for Western avionics instead, resulting in delivery delays from late 2005 until around 2007. Pakistani authorities evaluated avionics suites from Britain, France, and Italy, with a final selection anticipated in 2006. The fourth prototype, PT-04—incorporating these updates—was introduced in April 2006 and achieved first flight on April 28.

The revamped air intakes replaced traditional ramps with a diverterless supersonic inlet (DSI) design—characterized by forward-swept inlet cowls paired with a three-dimensional compression surface that redirects boundary layer airflow during high subsonic and supersonic speeds. Lockheed Martin notes that DSI technology reduces weight by eliminating complex mechanical intake components while enhancing stealth capabilities relative to conventional intake designs. Development commenced in 1999 with finalization by 2001; wind tunnel experiments confirmed reductions in weight, cost, complexity alongside performance improvements.

For flight testing focused on avionics and weapons certification, PT-04 was outfitted with a fourth-generation avionics suite featuring sensor fusion capabilities, an electronic warfare package, improved man-machine interface elements, Digital Electronic Engine Control (DEEC) for RD-93 engines, fly-by-wire controls, precision day/night surface attack functionality, and multi-mode pulse-Doppler radar optimized for beyond visual range air combat. The sixth prototype, PT-06, completed its maiden sortie on 10 September 2006. Following a competitive process in 2008, Martin-Baker was selected over a Chinese manufacturer to supply fifty PK16LE ejection seats for use in the JF-17 program.

Production

On 2 March 2007, the initial pair of small-batch-production (SBP) aircraft arrived in Pakistan in a disassembled state. These aircraft took to the skies on 10 March 2007 and were publicly showcased during an aerial demonstration at the Pakistan Day parade on 23 March. The Pakistan Air Force (PAF) intended to introduce 200 JF-17 fighters by 2015, aiming to phase out the Chengdu F-7, Nanchang A-5, and Dassault Mirage III/5 models. To facilitate training for aerial refueling, several Mirage III jets were retrofitted with IFR probes. Initially, a twin-seat combat trainer variant was scheduled for flight trials in 2006; by 2009, Pakistan sought to evolve this into a dedicated attack version.

In November 2007, both the PAF and Pakistan Aeronautical Complex (PAC) conducted assessments of aircraft outfitted with a modified NRIET KLJ-10 radar and the LETRI SD-10 active radar homing air-to-air missile. PAC commenced production of JF-17 components in 2005, with sub-assembly manufacturing beginning on 22 January 2008. The PAF was set to receive six additional pre-production units in 2005, bringing the total to eight from an initial batch of sixteen. The target for achieving initial operational capability was the end of 2008. Final assembly operations within Pakistan started on 30 June 2009; PAC planned to produce between four and six aircraft that year, increase output to twelve in 2010, and maintain an annual production rate of fifteen to sixteen from 2011 onward, with potential expansion up to twenty-five units per year. On 29 December 2015, PAC announced the completion of its 16th JF-17 that year, pushing total production beyond sixty-six aircraft. Responding to growing global demand, PAC Kamra intended to enhance its manufacturing capacity.

In August 2007, Russia formalized an agreement permitting the re-export of 150 RD-93 engines from China to Pakistan for use in the JF-17 program. By 2008, however, the PAF expressed reservations about the RD-93 engine’s performance and indicated it would be installed only on the first fifty aircraft; there were reports suggesting potential adoption of the Snecma M53-P2 engine as an alternative. Mikhail Pogosyan, leading the MiG and Sukhoi design bureaus, reportedly advised Rosoboronexport to restrict RD-93 sales to China to protect MiG-29 export markets from competition. The JF-17 made its international debut at the 2010 Farnborough Airshow, although planned aerial demonstrations were canceled due to late participation decisions and licensing expenses. Later that year at Airshow China in Zhuhai, Russia and China signed a $238 million contract for supplying 100 RD-93 engines with options to procure an additional 400 units for the FC-1 fighter. Media sources reported that Pakistan aimed to increase JF-17 production by approximately 25% in 2016.

Continued advancements

During the JF-17 development, Pakistan collaborated with defence companies from Britain and Italy to supply avionics and radar systems. Potential radar candidates comprised the Italian Galileo Avionica Grifo S7, the French Thomson-CSF RC400 (a variant of the RDY-2), and the British SELEX Galileo Vixen 500E AESA radar. In 2010, reports indicated that the Pakistan Air Force chose ATE Aerospace Group to integrate French avionics and weaponry, prevailing over proposals from Astrac, Finmeccanica, and a Thales-Sagem partnership. This contract, valued at up to , aimed to upgrade fifty JF-17 aircraft starting in 2013, with an option for an additional fifty units. The package included the RC-400 radar, MICA air-to-air missiles, and various air-to-surface munitions. Negotiations also took place with South Africa regarding Denel A-darter air-to-air missiles.

In April 2010, after nearly a year and a half of discussions, the agreement was halted due to French apprehensions about Pakistan’s financial stability, safeguarding of technology, and lobbying efforts by India—an operator of numerous French-made jets. France favored the Pakistan Air Force acquiring Mirage 2000-9 fighters from the UAE instead, which would conflict with the JF-17 modernization plans. However, in July 2010, PAF Chief Air Marshal Rao Qamar Suleman refuted these claims, affirming that French representatives had assured him no such obstruction existed.

The production of Block 2 JF-17s commenced on 18 December 2013 at PAC Kamra. These variants introduced features such as aerial refueling capability, upgraded avionics, increased payload capacity, data link functionality, and enhanced electronic warfare systems. Manufacturing of Block 2 continued through 2016 before transitioning to the more sophisticated Block III version. By December 2015, delivery of the sixteenth Block II aircraft allowed formation of a fourth operational squadron.

On 17 June 2015, Jane's Defence Weekly confirmed that Block III would integrate an AESA radar system, a helmet-mounted display (HMD), and potentially an internal infrared search and track (IRST) sensor. Plans also included a two-seat variant. Although not officially confirmed, reports suggested improvements in flight management systems for Block III. Selex ES promoted its advanced cockpit upgrade package featuring a new mission computer, enhanced head-up display (HUD), multifunction displays (MFDs), and an expansive pilot display.

In July 2020, despite objections from India, Russian state-owned United Engine Corporation developed a new powerplant named RD-93MA specifically for Pakistan’s JF-17 fighter.

Design

Airframe

The aircraft’s structure utilizes a semi-monocoque design primarily composed of aluminium alloys complemented by high-strength steel and titanium in critical zones. It is engineered for a service life spanning 4,000 flight hours or approximately 25 years, with the initial major overhaul scheduled at 1,200 flight hours. The Block 2 variants incorporate increased composite materials to achieve weight reduction. The landing gear employs a retractable tricycle configuration featuring a steerable nose wheel and dual main gears equipped with hydraulic braking systems and automatic anti-skid functionality. The air intakes are designed to maintain optimal airflow during maneuvers involving high angles of attack.

The mid-mounted cropped-delta wings are equipped with leading-edge root extensions (LERX) near the wing roots that generate vortices enhancing lift during combat maneuvers. The conventional tail assembly consists of all-moving stabilators, a single vertical fin with rudder control, plus twin ventral fins beneath the fuselage. Flight controls merge traditional mechanical linkages with stability augmentation systems for yaw and roll axes along with a digital fly-by-wire (FBW) system governing pitch movements. Leading-edge slats and trailing-edge flaps adjust automatically to optimize turning capabilities. Production models feature a digital quadruplex FBW system controlling pitch and duplex FBW in roll and yaw axes.

The platform supports up to of combined ordnance, equipment payloads, and fuel distributed across seven hardpoints: two located at the wing tips, four beneath the wings, and one under the fuselage.

Cockpit

The cockpit is equipped with three sizable multifunction colour displays (MFDs) alongside an advanced heads-up display (HUD) featuring integrated symbol generation. Pilot controls include a centrally located stick managing pitch and roll, rudder pedals for yaw control, and a throttle positioned to the left side. Hands-on-throttle-and-stick (HOTAS) functionality is incorporated to improve pilot operational efficiency. The pilot’s seat is a Martin-Baker Mk-16LE zero-zero ejection model.

An electronic flight instrument system (EFIS) delivers comprehensive flight, tactical, engine, fuel, electrical, hydraulic, flight control, and environmental information via three vertically aligned colour MFDs arranged side by side. The wide-angle holographic HUD provides a minimum total field of view of 25 degrees. Both the HUD and MFDs are fully customizable to present any selectable data; notably, the central MFD is placed at the lowest position to allow space for a control panel between it and the HUD.

Avionics

The avionics software adopts an open architecture design, developed using the widely adopted C++ programming language instead of the military-centric Ada, broadening access to civilian programming expertise. The aircraft incorporates a health and usage monitoring system alongside automatic test equipment.

Its defensive aids system (DAS) combines several subsystems: a radar warning receiver (RWR) which identifies enemy radar direction and distance; an electronic warfare (EW) package located in the tail fin tip that interferes with hostile radars and interfaces with a missile approach warning (MAW) system. The MAW employs optical sensors to detect missiles across 360 degrees, relaying inbound missile information to cockpit displays and the HUD. A countermeasures dispensing system deploys decoys such as flares and chaff to counter threats. Planned upgrades include integrating an external self-protection radar-jamming pod.

The initial 42 JF-17 fighters delivered to the Pakistan Air Force are outfitted with the NRIET KLJ-7 radar, derived from China's KLJ-10 used on the Chengdu J-10. This radar supports multiple operational modes capable of handling up to 40 air, ground, and maritime targets; its track-while-scan feature can monitor 10 targets beyond visual range (BVR) and engage two simultaneously using radar-guided air-to-air missiles. Detection ranges for a target with a 5 m² radar cross-section are at least 105 km in look-up mode and 85 km or more in look-down mode. The platform can integrate both a forward-looking infrared (FLIR) pod and an infra-red search and track (IRST) system; it is believed that the Block 2 variant includes IRST capability.

To address limitations in precision targeting, Pakistan’s Air Force emphasized acquiring third-generation targeting pods such as the Thales Damocles. In 2017, Aselsan’s ASELPOD underwent successful testing and integration on the JF-17, with Pakistan procuring at least eight units to substantially improve precision strike performance.

A helmet-mounted sight (HMS), developed by Luoyang Electro-Optics Technology Development Centre of AVIC in conjunction with the JF-17 program, was first trialed on Prototype 04 in 2006 and publicly unveiled at the 2008 Zhuhai Airshow. This EO HMS tracks pilot head and eye movements to direct missiles toward visually acquired targets. Additionally, an externally mounted day/night laser designator targeting pod may be added for guiding laser-guided bombs (LGBs), utilizing a dedicated hardpoint beneath the starboard air intake for such pods. To maximize pod utility, tactical data links facilitate sharing target information with other aircraft lacking targeting pods.

Communication capabilities include two VHF/UHF radios; the VHF radio supports data link connectivity with ground stations, airborne early warning platforms, and combat aircraft to enable network-centric operations and improved situational awareness. Navigation functions rely on ring laser gyroscopes paired with GPS technology. An identification friend or foe (IFF) transponder distinguishes allied from hostile aircraft, while air combat maneuvering instrumentation (ACMI) assists in tracking aerial engagements during combat training.

Engine

The initial two production blocks of the JF-17 are equipped with a single Russian RD-93 turbofan engine, which is a variant derived from the Klimov RD-33 engine utilized in the MiG-29 fighter jet. This powerplant offers increased thrust alongside notably reduced specific fuel consumption compared to older turbojet designs, resulting in lower maintenance demands and expenses relative to twin-engine aircraft. With full internal fuel and no external stores, it achieves a thrust-to-weight ratio near 0.99. Air intake is supplied through dual bifurcated inlets.

The RD-93 engine is recognized for generating visible smoke trails. Since 2000, the Guizhou Aero Engine Group has been working on the WS-13 Taishan turbofan as a replacement for the RD-93. Modeled on the RD-33, this engine integrates modern technologies aimed at boosting performance and reliability, with projected thrust levels between 80 and 86.36 kN, an operational lifespan of approximately 2,200 hours, and a thrust-to-weight ratio of 8.7. A more powerful iteration of the WS-13, expected to deliver around 100 kN of thrust, is also under development. Flight trials featuring a JF-17 powered by the WS-13 commenced at the 2015 Paris Air Show.

In 2015, Pakistan Aeronautical Complex (PAC) reaffirmed its commitment to continue utilizing the RD-93 engine in its aircraft. Early reports from 2016 suggested Russia intended to supply engines directly to Pakistan, with PAC seeking partnerships for engine development and maintenance support.

Fuel system

The aircraft's fuel system comprises internal tanks located in both the wings and fuselage, holding a total capacity of , which are replenished through a single-point pressure refueling mechanism. To augment internal fuel reserves, external tanks are employed: one drop tank mounted on the centerline hardpoint and two additional tanks—either 800-liter or —mounted on inboard under-wing pylons. The system is compatible with in-flight refueling (IFR), greatly extending operational range and endurance; all Pakistan Air Force (PAF) production models feature IFR probes. In June 2013, PAF confirmed successful ground tests of these refueling probes, with aerial refueling operations beginning later that summer.

Armaments

The JF-17 can carry a maximum payload of up to across seven external hardpoints: one beneath the fuselage, two under each wing, and one at each wingtip. These stations interface via a MIL-STD-1760 data bus linked to the Stores Management System, enabling compatibility with munitions sourced from various countries. Internally, armament consists of a 23 mm GSh-23-2 twin-barrel cannon positioned beneath the port-side air intake; this can be swapped for a more powerful 30 mm GSh-30-2 twin-barrel cannon if required.

Typically, short-range infrared homing air-to-air missiles (AAMs) are mounted on wingtip pylons. The under-wing and fuselage hardpoints accommodate diverse ordnance and equipment such as targeting pods and multiple ejector racks, allowing each station to carry two 500 lb unguided bombs or laser-guided bombs (LGBs). Beyond visual range (BVR) active radar homing missiles like the PL-12/SD-10 integrate seamlessly with onboard radar and data-link systems for mid-course guidance updates. The aircraft is armed with PL-5E and PL-9C short-range missiles; in April 2021, integration was completed for the advanced PL-10E High-Off Bore Sight missile designed for within visual range engagements using helmet-mounted display/sight (HMD/S) technology. The Block 3 variant supports the PL-15E missile—the most sophisticated Chinese export BVR missile boasting an advertised range of up to 145 kilometers.

Unguided air-to-ground weaponry includes rocket pods, conventional gravity bombs, and Matra Durandal anti-runway munitions. Precision-guided weapons such as LGBs and satellite-guided bombs are also compatible, along with anti-ship and anti-radiation missiles. In 2014, Pakistan intended to equip its JF-17 fleet with the Brazilian MAR-1 anti-radiation missile system.

Operational history

Pakistan

Production of the single-seat, single-engine JF-17 commenced in China with a limited initial batch in June 2006. The first two units were delivered on 2 March 2007 and made their inaugural flight in Pakistan on 10 March. These aircraft featured prominently in the Pakistan Day Joint Services Parade held in Islamabad on 23 March 2007. By March 2008, an additional six JF-17s had been supplied and subjected to rigorous flight testing by the Pakistan Air Force (PAF). Two more serial production models arrived from China in 2009, followed by the delivery of the first domestically assembled JF-17 on 23 November of the same year.

The inaugural JF-17 squadron, designated No. 26 Black Spiders, was officially commissioned on 18 February 2010, initially comprising 14 fighters. These aircraft were actively deployed during Operation Rah-e-Nijat, an anti-terrorism campaign, where they were used to assess a variety of weapons systems. Furthermore, they took part in the PAF’s High Mark 2010 exercise, executing precision air-to-surface strike missions.

A ceremony on 11 April 2011 marked a significant milestone in PAF modernization, emphasizing the JF-17's transformative role; Air Chief Marshal Rao Qamar Suleman publicly acknowledged the crucial technological support provided by China.

Throughout Operation Zarb-e-Azb (2014–2016), JF-17s regularly conducted airstrikes targeting Tehrik-i-Taliban Pakistan (TTP) strongholds, reportedly neutralizing hundreds of militants. In September 2015, No. 2 Squadron, tasked with maritime strike duties, transitioned from F7 aircraft to JF-17s. Additionally, No. 16 Squadron "Black Panthers" also operates this fighter type.

On 19 June 2017, reports indicated that a JF-17 intercepted and shot down an Iranian unmanned aerial vehicle (UAV) intruding over Pakistan’s Panjgur District.

During the February 2019 escalation in Jammu and Kashmir, JF-17s executed retaliatory airstrikes against Indian ground targets utilizing Mk. 83 REK bombs. By March 2021, seven fighter squadrons stationed across five airbases had incorporated the JF-17 into their operational fleets.

Since its debut at international airshows starting in 2010, the JF-17 has been regularly showcased globally. It has also participated in joint military exercises alongside the Chinese People’s Liberation Army Air Force (PLAAF) since at least 2014. In 2021, the aircraft took part in Turkey’s Anatolian Eagle exercise alongside air assets from Azerbaijan, Qatar, and Turkey itself. The following year saw its involvement in Saudi Arabia’s "Spears of Victory" drills conducted with Saudi and United States forces.

The PAF inducted its initial batch of JF-17 Block 3 fighters in March 2023.

In January 2024, JF-17s carried out retaliatory strikes against Baloch separatist factions operating within Iran’s Sistan and Baluchestan province, reportedly eliminating nine insurgents and damaging terrorist infrastructure.

During the India–Pakistan conflict of May 2025, the PAF publicly exhibited a JF-17 Block 3 outfitted with PL-15E long-range beyond-visual-range air-to-air missiles (BVRAAMs). Both JF-17s and Chengdu J-10CE fighters were deployed for multi-role missions encompassing air-to-air and air-to-ground operations. Pakistan asserted that one of its JF-17s successfully destroyed an Indian S-400 missile defense installation located at Adampur Air Force Station on 10 May using CM-400AKG long-range supersonic air-to-surface missiles.

However, India’s Ministry of External Affairs refuted these claims, affirming that all S-400 squadrons remained fully operational. To reinforce this position, Indian Prime Minister Narendra Modi visited Adampur Air Force Station on 13 May to demonstrate the missile system's active status as a direct response to Pakistan’s assertions.

Myanmar

In July 2015, Myanmar placed an order for 16 Block 2 JF-17 fighter jets from Pakistan and China, with the contract valued at around $560 million. Later that year, Myanmar acquired 16 RD-93 engines as spares from Russia, which were delivered during 2018 and 2019. By December 2018, the Myanmar Air Force had received its initial batch of JF-17s, which were featured in official footage released on Air Force Day. Up to now, Myanmar has taken delivery of seven JF-17 Block 2 aircraft, comprising five single-seat and two dual-seat models.

In May 2022, a cargo aircraft from the Pakistan Air Force transported spare parts for Myanmar’s JF-17 fleet. By June 2022, a contingent of 15 Pakistan Air Force personnel was scheduled to visit Meiktila Air Base to offer technical assistance, set up a JF-17 simulator for pilot training, and address operational challenges. Additionally, Myanmar is in discussions with Pakistan regarding the procurement of air-to-ground missiles compatible with its JF-17s.

Nigeria

During the International Defence Exhibition held in Karachi in December 2014, Nigeria reportedly engaged in negotiations to acquire between 25 and 40 JF-17 jets from Pakistan. Earlier in October 2014, Nigerian Air Force (NAF) Chief Air Marshal Adesola Nunayon Amosu had visited Pakistan. Nigeria became the second international customer in 2016 by placing an order for three aircraft; however, some reports estimated the deal at US$25 million, which raised questions about its accuracy. A June 2016 report reaffirmed the NAF’s budget allocation for three JF-17s alongside other aircraft purchases, with official confirmation following shortly thereafter.

In October 2018, Pakistan authorized the sale and local assembly in Nigeria of three JF-17s for US$184.3 million, likely reflecting a more advanced variant equipped with upgraded systems.

On 30 December 2020, Pakistan Aeronautical Complex (PAC) unveiled three JF-17A Block 2 fighters destined for the Nigerian Air Force. These aircraft were delivered to Makurdi Air Base in March 2021 via Ilyushin Il-78MP transport planes operated by the Pakistan Air Force. Nigeria officially inducted these jets into service on 21 May 2021.

The Nigerian Air Force is considering placing an additional order for 35 to 40 JF-17s contingent upon satisfactory operational performance. In January 2023, NAF Chief Air Marshal Isiaka Oladayo Amao confirmed that the JF-17s have been actively deployed in anti-terrorism and counter-insurgency missions within Nigeria.

Azerbaijan

Negotiations between Azerbaijan and Pakistan regarding potential acquisition of JF-17 fighter jets began in January 2008. By 2015, discussions between Azerbaijani Air Forces and China focused on procuring several dozen JF-17s, each priced at approximately . In 2018, military talks between officials from Pakistan and Azerbaijan intensified as Azerbaijan demonstrated strong interest in obtaining the JF-17 Thunder aircraft.

On 22 February 2024, Azerbaijan finalized a contract worth US$1.6 billion with Pakistan for an undisclosed number of JF-17 Block 3 multi-role combat jets, which included provisions for training and weapons support. Subsequently, on 25 September 2024, the JF-17 Block 3 was presented to Azerbaijan’s President during the Azerbaijan International Defence Exhibition (AIDEX) held that year.

Pakistan announced on 6 June 2025 a $4.6 billion agreement to supply Azerbaijan with 40 units of the JF-17 Block 3 fighter jets. This contract extends the earlier deal signed in 2024 and encompasses aircraft delivery, pilot training programs, and armament packages—making it the largest fighter jet transaction ever conducted between these two nations.

Potential buyers

• Bangladesh In January 2025, Bangladesh indicated an interest in acquiring the JF-17 Block 3.
• Iraq From 2023 onwards, Iraq has aimed to upgrade its air force with the JF-17 fighter. Following the procurement of 12 PAC MFI-17 Mushshak trainer aircraft, Iraq entered into a $1.8 billion agreement to purchase an additional 12 Mushshaks along with 12 JF-17 Block III fighters. This contract was signed in Baghdad between Pakistan’s Chief of Air Staff and Iraqi defense representatives. Iraq became the fourth country to operate the JF-17 after Myanmar, Nigeria, and Azerbaijan.
• Additional nations Countries such as Egypt, Jordan, Kuwait, Peru, South Africa, Uruguay, and Venezuela have demonstrated interest in the JF-17 platform.

Previous prospects

• Argentina During the 2013 Paris Air Show, Argentine aerospace company Fábrica Argentina de Aviones (FAdeA) revealed ongoing talks with Chinese officials regarding possible joint production of the FC-1/JF-17 for the Argentine Air Force (FAA), marking Argentina’s initial formal step toward acquiring or co-producing this aircraft. FAdeA proposed naming the co-produced FC-1 as "Pulqui-III," in homage to its historical Pulqui-II fighter.

Following Argentine president Cristina Fernández de Kirchner’s visit to China in 2015, Argentina considered purchasing approximately 20 JF-17s from CAIG, though this transaction did not come to fruition. A key factor was the aircraft’s limited British-origin components, thereby avoiding UK-imposed military export restrictions post-Falklands War.

Earlier Argentine efforts to procure fighters such as the Mirage F1M, IAI Kfir, JAS 39 Gripen, and KAI FA-50 were hindered due to inclusion of British-made parts.

In September 2021, Argentina’s draft budget for 2022 allocated USD $664 million for future fighter acquisitions; media reports erroneously linked this funding specifically to a JF-17 Block III purchase. The Ministry of Defense clarified no final decision had been made, with five other aircraft models under consideration.

By May 2022, FAA representatives conducted evaluations of the JF-17 in China.

As of October 2023, the United States approved transferring 24 used F-16 Block-15 MLU jets from Denmark to Argentina, reportedly without British consent. Following the inauguration of the pro-US government under Javier Milei, Argentina reportedly opted for the F-16 over the JF-17.

• Bolivia The Bolivian Air Force is considering the JF-17 as a replacement for its retired Lockheed T-33 trainers.

• Congo In March 2023, China proposed selling the JF-17 to the Democratic Republic of the Congo.

• Malaysia Malaysia has intermittently shown interest in procuring JF-17s for its Royal Malaysian Air Force (RMAF) as replacements for its MIG-29 fleet; initial reports from 2015 were later refuted. In March 2019, then Prime Minister Mahathir Mohamad received a briefing and was presented with a JF-17 display during Pakistan Day celebrations. Unconfirmed reports suggested Malaysia planned to acquire two JF-17s for evaluation purposes.

In June 2021, RMAF issued a tender seeking 18 light combat aircraft (FLIT/LCA) intended to replace aging BAE Hawk and MB-339 trainers. By October, six companies had submitted bids; notably, the JF-17 was absent from this competition, dispelling speculation about its acquisition by Malaysia.

In December 2021, reports indicated China re-offered the JF-17 at approximately a 30% price reduction; however, RMAF declined and subsequently procured 18 FA-50 Block 20 jets in March 2023.

• Morocco Morocco expressed interest by inviting a sales delegation to participate at Marrakech Air Show in 2016; however, acquisition challenges arose due to technological incompatibilities between various JF-17 variants and Morocco’s existing Western-origin fleet.

• Qatar Since 2016, Qatar has shown interest; PAF’s JF-17s took part in Qatar’s National Day flypast in December 2019 alongside Rafale and Mirage aircraft. Despite this, Qatar ultimately selected Eurofighter Typhoon and F15E fighters.

• Saudi Arabia In January 2014, Saudi Arabia explored options involving technology transfer and joint production related to the JF-17; Prince Salman bin Sultan visited the project site. By 2023, Saudi focus had shifted toward participation in the Anglo-Italo-Japanese Global Combat Air Programme.

• Sri Lanka Pakistani media reported in June 2015 that Sri Lanka ordered approximately 18–24 aircraft worth around $400 million; however, Sri Lankan officials denied these claims. Indian diplomatic influence is believed to have impeded any agreement. By 2021, Sri Lanka opted instead to refurbish existing Kfirs rather than pursue new acquisitions due to budget constraints.

• Zimbabwe Zimbabwe planned a $240 million acquisition of twelve JF-17s back in 2004; however, no transaction was completed. By 2010, China was reportedly negotiating with multiple countries concerning the JF-17 program, with some sending pilots for evaluation flights.
