As India bolsters its aerial shield with the expected arrival of its fourth S-400 missile squadron by mid-2026, the Pakistan Air Force (PAF) is reportedly developing a novel strategy to counter this growing advantage.
According to recent analyses, Pakistan plans to transform its ageing and retired Chengdu F-7PG fighter jets into fast, unmanned combat drones.
This ambitious initiative aims to create a new method for piercing India's sophisticated, multi-layered air defence network.
The idea is far from mere speculation and draws heavy inspiration from Beijing's military playbook.
Recent intelligence indicates that China has successfully retrofitted hundreds of its obsolete J-6 and J-7 aircraft into operational drone variants, deploying them near the Taiwan Strait.
Pakistan seeks to mirror this approach by turning its own outdated planes into disposable, fast-moving tools meant to flood and exhaust enemy radar and missile networks.
The core of this program relies on a "Zombie Jet" modification technique.
Engineers remove all equipment required by a human pilot—such as manual flight controls, oxygen tanks, dashboard instruments, and ejection mechanisms.
Removing these components drastically cuts down the aircraft's weight, creating ample room for explosives or advanced electronic gear.
To fly the jet, domestic defence contractors are installing autonomous navigation systems that rely on GPS and inertial sensors, which can be pre-programmed or steered remotely through encrypted communication channels.
To help these drones survive their journey into hostile territory, they are being designed to fly dangerously close to the ground.
By hugging the terrain at altitudes of less than 100 metres, these automated jets can evade early radar detection, significantly narrowing the window of time that long-range surface-to-air missiles have to lock on and intercept them.
Strategists primarily view these modified jets as bait, designed specifically to draw fire from high-end systems like the S-400.
Because the original F-7PG has a prominent radar signature, the unmanned versions will look exactly like piloted F-16 or J-10CE fighters on an operator's screen.
If sent in swarms, they would force Indian forces to make a difficult choice: waste multi-million-dollar interceptor missiles on empty, low-cost drones, or hold their fire and risk a genuine attack getting through.
To make the deception even more convincing, the drones can carry radar-enhancing devices that artificially inflate their visibility.
This tactic deliberately provokes defence batteries into turning on their tracking radars, exposing their hidden locations so that subsequent waves of actual fighter jets can target them with precision weapons.
India's highly effective use of the S-400 during the May 2025 border skirmishes likely accelerated Pakistan's need for such decoy tactics.
In addition to acting as decoys, these zombie jets can serve as devastating kamikaze weapons.
While most military drones fly at relatively slow speeds, a retrofitted F-7 can still travel at nearly twice the speed of sound. Observers note that this effectively turns the aircraft into a massive, nine-tonne cruise missile.
Without a pilot on board, the jet can be packed with up to two tonnes of explosives, giving it the kinetic energy and destructive power needed to obliterate reinforced bunkers or critical infrastructure.
These dual functions are intended to be used in a staged, multi-wave assault plan.
During a potential conflict, a frontline wave of unmanned F-7s would cross the border first to activate and map the opponent's defensive grid.
Immediately after, standard combat aircraft would fire specialised missiles at the newly exposed radar installations.
With the air defences temporarily blinded or depleted, a final wave of advanced strike fighters could move in to safely eliminate primary targets.
Despite the strategic advantages, Pakistan must overcome severe engineering obstacles to make this a reality.
Maintaining secure and instant communication with a jet flying at supersonic speeds is incredibly difficult, and these digital links are highly susceptible to electronic jamming by modern militaries.
Furthermore, creating a fully autonomous system capable of navigating obstacles and making split-second decisions in a chaotic combat zone requires processing power and artificial intelligence that are still largely experimental on a global scale.
Nevertheless, there are signs that the concept is moving beyond the drawing board.
Satellite photographs taken in late 2025 captured abnormal flight routines at airbases such as Mianwali, where F-7PG jets were observed performing automated takeoffs and landings.
While Pakistani authorities have not publicly acknowledged the program, these activities strongly indicate that real-world testing of the drone conversion technology has already begun.
