Development Program for JF-17 PFX (Pakistan Fighter Experimental) Unveiled

The development program for Pakistan's JF-17 Pakistan Fighter Experimental (PFX) will elevate the fighter jet's capabilities beyond those of the JF-17 Block III variant, which is currently the most advanced and capable version of the aircraft.
(DEFENCE SECURITY ASIA) – Recognizing the need for continuous upgrades to the JF-17 “Thunder” fighter jet, Pakistan and its development partner China have launched a new development program called the JF-17 PFX (Pakistan Fighter Experimental).
This program aims to enhance the JF-17 to a level surpassing the capabilities of the JF-17 Block III variant, currently the most advanced and capable version of the fighter.
The JF-17 fighters are jointly developed by the Pakistan Aeronautical Complex (PAC) and China’s Chengdu Aircraft Industry Group (CAIG).
According to defense media reports, the JF-17 PFX is expected to be larger and heavier than the current JF-17 variants, placing it in a similar size and weight category to India’s Tejas MkII fighter jet.
The PFX will feature state-of-the-art technology, including advanced avionics, enhanced radar capabilities, and a higher weapons payload capacity, enabling it to undertake a wide range of combat missions.

Although specific details about the JF-17 PFX development remain scarce as the program is still in its early stages, Pakistan’s efforts signal its determination to maintain its air force as a dominant regional power.
The JF-17 PFX will ensure that the Pakistan Air Force (PAF) possesses a fighter jet capable of competing with, and potentially surpassing, the capabilities of other regional aircraft such as the Tejas MkII, Rafale, and Su-30MKI.
The PFX program is part of Pakistan’s broader strategy to modernize its air force and reduce reliance on foreign suppliers, aiming for greater self-sufficiency in defense production. Currently, PAC is responsible for producing 58 percent of the JF-17 airframe, with the remain
 components manufactured by its Chinese partner. However, to ensure the long-term viability of the PFX, Pakistan will need to increase its domestic production capabilities, ultimately striving for complete self-reliance.
Achieving this will not only bolster Pakistan’s aerospace independence but also position the country as an emerging player in the global defense and aerospace industries.
JF-17
At present, the Pakistan Air Force is believed to operate around 100 JF-17 Block I and Block II aircraft.
Recently, Defence Security Asia reported that production of the JF-17 Block III variant in Pakistan has exceeded 20 units and is nearing 30 aircraft, part of an ongoing order for the PAF.
The JF-17 Block III, the latest variant, first flew in 2019 and entered serial production in 2022.
 Its most significant upgrades include the integration of the KLJ-7A Active Electronically Scanned Array (AESA) radar, a Helmet Mounted Display and Sight (HMD/S) system, and advanced Electronic Countermeasures (ECM).
In terms of armament, the Block III variant is capable of launching long-range PL-15E air-to-air missiles, with a claimed range of 145 km.

It can also deploy PL-10E High-Off Boresight air-to-air missiles, guided by the HMD/S during Within Visual Range (WVR) combat.
Reports also suggest that the JF-17 Block III is now equipped to launch the “Taimur” Air-Launched Cruise Missile (ALCM), capable of striking both static and moving targets, including warships, at distances up to 280 km.
The Block III variant reportedly shares similarities with China’s J-10C fighter, which is also in service with the Pakistan Air Force, and is said to incorporate elements of China’s fifth-generation J-20 “Mighty Dragon.” — DSA
