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 Engine 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.

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.
