Pakistan Air Force working on modern PFX Alpha jet development program
The Pakistan Air Force (PAF) is
pursuing a dual-track approach in its fighter development program, combining
the evolutionary PFX Alpha upgrade with a heavyweight pathway linked to
Turkey’s KAAN fifth-generation fighter platform. This strategy allows rigorous
evaluation of emerging technologies, operational doctrines, and tactical
requirements, ensuring flexibility in selecting the architecture that best
balances performance, sovereignty, and cost-effectiveness.
The PFX Alpha serves as a spiral
development initiative, using a modified JF-17 Thunder as a live testbed for
maturing critical systems. This track emphasizes open-architecture mission
computers, the indigenous Murad AESA radar from the National Aerospace Science
and Technology Park (NASTP), gallium-nitride liquid-cooled radar arrays,
advanced sensor fusion, and integrated electronic warfare suites. With full
source-code control retained by Pakistan, modifications and upgrades can be
implemented independently, reducing foreign reliance. The program, highlighted
as the Operational Capability Upgrade (OCU) at defense exhibitions such as
IDEAS 2024, represents the first step toward broader PFX ambitions.

This incremental approach de-risks future platforms by prioritizing the maturation of avionics and sensor systems before committing to major airframe changes. Flight-test data from the JF-17 platform inform decisions on twin-engine configurations, diverterless supersonic inlets (DSI), and internal weapons bays. The strategy builds domestic expertise in avionics integration and radar technology, reinforcing NASTP’s role in fostering indigenous capability and enhancing situational awareness and multi-role effectiveness.
In parallel, the KAAN-linked pathway
offers a high-end fifth-generation stealth fighter option. Originating from
Turkish Aerospace Industries’ KAAN program, this track focuses on internal
weapons carriage, multispectral sensors, and survivability in contested
airspaces. Pakistan’s contributions include sovereign adaptations, such as
integration with the Link-17 datalink for network-centric operations. Bilateral
agreements, including joint production arrangements finalized during the 2025
Pak-Turkish Industrial Expo, enable co-manufacturing and technology transfer,
supported by hundreds of Pakistani engineers contributing to KAAN development.
This dual-track approach is
strategic rather than redundant. The PFX Alpha emphasizes systems sovereignty,
cost-efficient scaling, and rapid integration into existing squadrons,
leveraging the proven JF-17 platform for incremental gains. The KAAN pathway,
by contrast, targets stealth superiority and extended operational reach,
addressing high-threat scenarios. Final decisions on the definitive PFX fighter
will be guided by empirical performance data and operational balance rather
than theoretical specifications.

Experts highlight that layered modernization is essential given regional airpower advancements. The PFX Alpha ensures near-term relevance by upgrading combat-proven assets, while the KAAN option offers a leap toward fifth-generation parity. Evaluations from both tracks will determine the optimal fusion of capabilities to meet evolving doctrinal requirements.
Pakistan’s dual-path strategy
reflects foresight in resource allocation, industrial growth, and international
partnerships. Alongside cooperation with Turkey, potential collaborations with
China contribute to a diversified development portfolio aimed at sustaining
airpower modernization for decades to come.
