Pakistan's Homegrown Link-17 Kill Chain Helped Shoot Down India's Rafale Fighter Jets

Using a homegrown datalink (Link-17) communication system, Pakistan has integrated its ground radars with a variety of fighter jets and airborne early warning aircraft (Swedish Erieye AWACS) to achieve high level of situational awareness in the battlefield, according to experts familiar with the technology developed and deployed by the Pakistan Air Force. This integration allows quick execution of a "kill chain" to target and destroy enemy aircraft, according to experts. This capability was demonstrated recently in the India-Pakistan aerial battle of May 7-8 that resulted in the downing of several Indian fighter jets, including the French-made Rafale.

Pakistan Air Force (PAF) pilots flying Chinese-made J10C fighter jets fired the Chinese PL-15 air-to-air missiles and shot down at least two Indian Air Force's French-made Rafale jets in history's largest ever aerial battle, according to multiple media and intelligence reports. India had 72 warplanes on the attack and Pakistan responded with 42 of its own, according to the Pakistani military.

Speaking on a recent podcast, Michael Dahm, a senior fellow at AFA’s Mitchell Institute for Aerospace Studies, said the kill chain may have started with a Pakistani ground radar—“maybe a surface-to-air missile system, or some other type of radar system”—which “illuminated the Indian target.” Then, a Pakistani J-10C fighter “launched its missiles, probably at range, and finally, an airborne early warning and control aircraft used a midcourse datalink to update and guide the missile to the Indian fighter.” “The Pakistani Air Force deployed …’ A’ launched by ‘B’ and guided by ‘C’” and hit the target, he added.

Link-17 enables secure and jam-resistant voice and data exchanges between connected assets. Combined with electronic warfare, it allows the Pakistani military to control the electromagnetic spectrum, giving access to the enemy communications and denying them access to their own. It also enables networked participants to view in real-time each other’s sensor feeds, which could come from radars, sonars, electro-optical (EO) systems such as cameras, and others. Link-17 has given the PAF a network protocol that it can use with a wide range of aerial assets, especially domestically driven programs, such as the JF-17 Thunder.

Military aviation analysts conclude from the results of the air battle that the Chinese technology is as good, if not better than, the western technology. However, it must be understood that the way the technology is actually deployed in the battlefield is as important in achieving good results as the technology itself. Also, the men count as much, if not more than, the machines. The legendary US Air Force pilot Chuck Yeager called Pakistan Air Force pilots "the best in the world". In another tweet in 2015, Yeager said "they (PAF pilots) kicked the Indians butt".

Has Pakistan Destroyed India's S-400 Air Defense System at Adampur?

Pakistan claims its air force (PAF) has destroyed India's high-value Russian-made S-400 air defense system (ADS) located at the Indian Air Force (IAF) Adampur air base. India has rejected this claim and posted pictures of Prime Minister Narendra Modi posing in front of its S-400 rocket launchers in Adampur. Meanwhile, there are reports that an Indian S-400 operator, named Rambabu Kumar Singh, was killed at about the time Pakistan claims to have hit it. Pakistan is believed to have targeted the S-400 systems using precision-guided CM-400AKG hypersonic missiles (max range 250 kilometers) launched from its JF-17 fighter aircraft.

How can an independent observer decipher the truth in the midst of these claims and counterclaims? To do that, one must first understand what constitutes the S-400 ADS. Is it just the rocket launchers? Or does it have other critical components like the radar and command-and-control systems? Could it be that the Pakistanis left the launchers alone and targeted and destroyed the radar and the command and control systems? Is that why the system operator was killed?

What is Russia's S-400 ADS?

The S-400 air defense system is designed to provide a layered defense with varying range capabilities. Its primary missiles, the 40N6, have a range of 400 kilometers (250 miles), while the 48N6E3 missiles offer a range of 250 kilometers (160 miles). The S-400 can also engage targets at shorter ranges using the 9M96E and 9M96E2 missiles, with ranges of 40 and 120 kilometers (25 and 75 miles), respectively. The S-400 consists of multiple components. Here's how it works.

1. Long-range surveillance radar tracks objects and relays information to the command vehicle, which assesses potential targets.

2. Target is identified and the command vehicle orders missile launch.

3. Launch data is sent to the best placed launch vehicle and it releases surface-to-air missiles.

4. Engagement radar helps guide missiles towards the target.

The entire system is rendered useless if any of these components are damaged or destroyed.

Death of an S-400 Operator:

Indian news outlet First Bihar reported the death of an Indian soldier operating the S-400 Air Defense System in Indian Occupied Jammu and Kashmir at Adampur Airbase on May 10, 2025. This report was later deleted under pressure from the Indian government, in the same manner as The Hindu newspaper was forced to remove its story about the Indian Air Force's loss of French-made Rafale fighter jets in the aerial battle with the Pakistan Air Force.

India's NDTV Report:

Indian journalist Vishnu Som has confirmed in conversation with Shiv Aroor on NDTV that two near-hypersonic missiles fired from a JF-17 jet targeted Adampur Airbase. One of the missiles reportedly missed, while the outcome of the second is unclear. Aroor added that certain sensitive details about the incident could not be publicly disclosed.

If indeed Vishnu Som's confirmation is accurate, then the question arises as to how did a JF-17 armed with CM-400AKG hypersonic missiles (max range 250 kilometers) gain access to the S-400 system which has anti-access/area denial (A2AD) capabilities? The S-400's long range and ability to engage various aerial threats, including ballistic and cruise missiles, allows it to create a large area where enemy aircraft and missiles are denied access or freedom of operation.

Summary:

While there has been no official confirmation of the loss at Adampur, there is considerable circumstantial evidence to suggest that the Pakistan Air Force's fighter jets damaged a Russian-supplied S-400 ADS system operated by the Indian military. This is not the first time a Russian-made S-400 air defense system has been damaged or destroyed. Ukraine destroyed one in Crimea last year. Apparently the S-400 has known vulnerabilities that could have been exploited by both Ukraine and Pakistan.
