Pakistan PFX vs India Tejas | 2028 Air Power Shift Explained | Fighter Jet Comparison
Is the balance of power in Asia's airspace going to completely shift by 2028? Could Pakistan’s PFX program become an important development in the country’s future fighter fleet, and how might it compare with India’s Tejas program?
In this Article, we'll discuss two fighter jets from two nations that were designed to be used against each other. But one of these fighters has progressed significantly, while the other remains a victim of basic development problems. On one hand, there's the Pakistan Air Force's PFX program, Pakistan has discussed future fighter development under the PFX concept, with some reporting and analysis pointing toward a possible first flight around 2028.
Lets Start :
🇵🇰 Pakistan PFX Program (Future JF-17 Evolution)
The Pakistan Air Force's decision to advance the JF-17 Thunder to the PFX (Pakistan Fighter Experimental) stage is not just an economic breakthrough, but a profound strategic message. Pakistan's goal is to develop a 4.5-generation platform by 2028 that will not only be a major leap forward in radar and electronic warfare, but also be equipped with the latest sensors and weapons developed with China's cooperation.
Technically, the PFX program will take the successes of the JF-17 Block 3 to the next level. Its scale model, unveiled at the Ideas 2024 exhibition, indicates that Pakistan is now moving towards a machine that will have a diverter less supersonic design.
Supersonic air inlets and innovative composite materials will be used to reduce its radar cross section. While it won't be fully stealth-ready, the design changes will make it a difficult target for Opponent-radars. Furthermore, the new-generation radar and infrared search and track system it will be equipped with will enable it to silently track and target the opponent without having to rely on its radar signals. This passive targeting capability could be the difference between life and death in modern military warfare.
Some reports and speculation have suggested that a future PFX design could adopt a twin-engine configuration, but this has not been officially confirmed. If this proves true, it would be the biggest breakthrough for the JF-17 family so far. A twin-engine configuration could potentially provide greater thrust, payload flexibility, and redundancy, but its actual advantages would depend on the final aircraft design. This aircraft will not only be used for air dominance but will also become Pakistan's main platform for deep strike and reconnaissance missions.
However, a twin-engine design would require a full redesign of the airframe, changing the structure, which would need a lot of time, energy, and money. Many believe Pakistan may not go for this due to cost and development constraints. Long-range missiles like China's PL-15 will give it beyond visual range capability, which India will have to counter with its more expensive Rafale variants.
The PFX program's greatest strength is its network-centric warfare design. The system will not fight alone but will operate in a fully integrated data-sharing environment with satellites, ground-based- radars, and AWACS systems. This means the PFX pilot will be able to know the opponent position without turning on onboard radar, as the information will already be available through the network.This could improve situational awareness and reduce the need for continuous use of the aircraft’s own radar in some tactical situations..
The pace of Pakistan’s PFX program is supported by China’s aviation ecosystem, allowing technology transfer and rapid prototyping. Pakistan’s model is based on a hybrid industry where it relies on China for core design and technology, but keeps assembly, avionics integration, and software control in its own hands.
This hybrid model could reduce dependence on a single external supplier for some aspects of assembly and integration, although it would not eliminate supply-chain or sanctions-related risks.
🇮🇳 India Tejas Program (Mark 1A)
On the other hand, the situation with India's Tejas Mark 1A appears quite complicated. India has ordered approximately 180 fighters worth over $1.5 billion, but By April 2026, deliveries of the Tejas-Mk1A had faced significant delays, with engine availability among the reported constraints. The biggest reason for this is delays in the production of F404 engines by the US company General Electric. While Pakistan has restructured its supply chain to combine Chinese technology with local manufacturing for faster production, India still depends on Washington for critical components despite its self-reliance policy.
Now, let's look at the other side of this competition. It is not only the properties of the indicated fighter jets, but also their quantities and overall presence on the battlefield that might make a noticeable difference.
Considering such parameters as multi-role capability, speed (Mach 1.6/1.8), and weight (around 3500 kg), there are no significant differences between the JF-17 Block 3 and Tejas Mark 1A.
Nevertheless, Pakistan currently has a larger operational JF-17 fleet, giving it an established fleet-size and deployment advantage in this particular comparison. Indeed, the country has already commissioned seven squadrons of JF-17, which comprises the core of the Pakistan Air Force.
At the same time, India has faced serious challenges in building its air power with Tejas. Although its mark 1A version is superior in many aspects, India continues to face a gap between its current fighter squadron strength and its long-standing authorized target of 42 squadrons.
Furthermore, India is now trying to modify Tejas Mark 1A to be able to host more advanced radars and electronic warfare systems; however, their availability and practical implementation in time remain doubtful.
Strategic Industrial Competition
The PFX program’s biggest strength is its network-centric warfare design. The aircraft will not fight alone but will operate in a fully integrated data-sharing environment with satellites, ground radars, and AWACS systems.
Pakistan’s development process is significantly advanced due to China’s aviation ecosystem, which allows for rapid prototyping of its aircraft and transfer of technology Knowingly or not, Pakistan has adopted a hybrid approach to industrialization, wherein China is responsible for the design and technologies while Pakistan assembles, integrates, and installs software controls. This protects
Pakistan from global sanctions and supply chain disruptions. In contrast, India has chosen a more difficult path for Tejas, aiming to manufacture everything domestically. While this is good for long-term independence, in the current military environment it has become a strategic burden due to slow progress.
In 2028 and beyond, PFX will not only compete with Tejas but also with India’s most expensive fighter programs. Pakistan’s strategy is to develop a low-cost aircraft capable of matching advanced 4.5-generation fighters. If the PFX enters large-scale production in the early 2030s, Pakistan could have a modern fleet ready for both defensive and offensive missions. By then, India’s AMCA or fifth-generation program may still be in testing phases.
However, the success of this program depends on financial resources and continued cooperation with China. Similarly, India now faces the challenge of improving the efficiency of its aerospace institutions. In conclusion, PFX is not just a single aircraft, but a broader effort to maintain Pakistan’s air priority.
This program shows that modern wars are not won by big budgets alone, but by choosing the right technology at the right time and executing it quickly. The year 2028 will be a turning point in Asia’s geopolitics and air power balance. Will India overcome its delays, or will Pakistan’s PFX emerge as the new “sultan of the skies”?
This is a question only time will answer.

CONCLUSION :
The comparison between Pakistan’s PFX concept and India’s Tejas Mk1A highlights two different stages of fighter development. The Tejas Mk1A is an established aircraft program moving through production and induction, while the PFX remains a future development whose final design, engine, performance and timeline have yet to be demonstrated.
If Pakistan’s PFX program progresses as planned, it could introduce more advanced sensors, electronic-warfare capabilities, networking and other modern features into Pakistan’s future fighter fleet. However, its eventual capabilities cannot be judged reliably until the aircraft reaches flight testing and its specifications become clearer.
For India, the continued development and production of the Tejas family remains an important part of its effort to strengthen indigenous fighter production and address its wider fleet requirements.
Ultimately, the PFX–Tejas comparison is not simply about which aircraft is better. It is about future development versus an aircraft already moving toward wider operational deployment. The real comparison will become clearer once the PFX flies, enters testing, and its actual capabilities are publicly demonstrated.
Do you think Pakistan’s PFX program will complete its first flight by 2028, and is the Tejas delay an irreparable loss for India? Share your thoughts in the comments.
