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.

    Pakistan received first one 'J35A Gyrfalcon' (Pakistan Flag coloured).
    Test flight successfully conducted in Gilgit Baltistan, Pakistan together with Chinese Pilots.


    https://x.com/TheRealFalcons5/status/1925593329862865339

    -------------------

    Gilgit-Baltistan, May 2025— In a development that has stunned Western observers and forced doctrinal recalibration across South Asia, China and Pakistan have jointly test-flown the first Pakistan-liveried J-35A 'Gyrfalcon' stealth fighter over the Karakoram. The flight was carried out with Chinese and Pakistani pilots aboard, fully integrated with Beidou satellite command, AWACS uplink, and ground-based stealth-tracking denial systems.

    But this wasn’t just a test of technology—it was a demonstration of trust. It marked a transformation of Pakistan’s role from a tactical partner to a privileged strategic ally—one now privy to China’s most advanced combat doctrine.

    “This isn’t just cooperation. It’s full-spectrum fusion.”
    A senior European defense attaché based in Islamabad told us on background:

    “We knew the J-35 would be exported. But we didn’t expect Pakistani pilots to be inside the cockpit before full PLAAF deployment. That’s unprecedented. This isn’t just cooperation. It’s full-spectrum fusion.”

    According to multiple military observers, the J-35A flights over Gilgit-Baltistan were not simulations.

    They were high-fidelity integration drills, including:

    Real-time radar suppression exercises
    Satellite-guided targeting against virtual enemy airframes
    Live interception of AWACS and low-observable drone targets
    Simulated Rafale/Meteor scenario tracking
    These were not “orientation flights.”
    They were doctrinal rehearsals.

    A Stealth Jet—and a Strategic Message

    A former Indian Air Marshal, speaking anonymously to a UK-based defense publication, admitted:

    “If Chinese and Pakistani pilots are flying J-35As in combat configurations, it fundamentally changes the balance. The Rafale edge we built is gone. Stealth has reached our borders.”

    The J-35A is China’s answer to the F-35, and the fact that it’s being tested in Pakistani airspace under joint command is a clear message to both India and the West:
    China trusts no one more than Pakistan with its crown jewel.

    Why This Is a Strategic First

    While Russia has exported Su-35s and is co-developing Su-75, it has not integrated any ally into its core fifth-gen doctrine. Nor has the U.S. allowed any non-NATO state full access to F-35 flight protocols.

    China just did.

    According to a Chinese defense analyst quoted in Global Times:

    “Pakistan is not just a customer. It is a doctrinal partner. The J-35’s deployment tests reflect the maturing of a joint deterrence framework.”

    What Does This Mean for the Region?

    India's Rafale-Meteor doctrine is now under question.
    The assumption of BVR superiority is neutralized by PL-15E range parity and J-35’s radar evasion.
    China has field-tested integrated battle cloud architecture in South Asia.

    This means AWACS, satellites, and stealth jets in unified command, with Pakistani coordination.
    CPEC is no longer just a road—it’s a shield.
    With Gilgit-Baltistan becoming an aerial bastion, Chinese stealth can now dominate the Siachen-Galwan axis if needed.

    “We’re Inside the System Now” A retired PAF Air Commodore, familiar with the test protocols, put it bluntly:

    “This isn’t just about receiving jets. It’s about being inside the operating system. We’re no longer flying Chinese jets—we’re flying with China, in China’s future.”

    With the J-35A, Pakistan hasn’t just closed the gap.
    It has entered the command structure of the next global aerial paradigm.

    The friendship is over.
    What exists now is strategic fusion.

    Silencing The Growler...

    NATO called it the "SA21 Growler"
    At Adampur AFS, India stationed its pride: the S-400 Triumph.
    The chilling hum of radar swept skies over Northern Punjab.
    Standing tall seeing everything that flew within 600kms.
    PAF knew they had to blind it.

    In the days leading up to the strike, a solitary DA20 Falcon slipped into the sky from Mushaf Air Force Base, hugging the border in silence. It wasn’t just flying; it was listening. Harvesting signals, dissecting radar emissions, peeling back the electronic curtain of the enemy’s air defense grid.

    But the groundwork had been laid even earlier. In 2024, during Exercise Indus Shield-C, the PLAAF had quietly brought in their own S-400s. Not just to show off; but to simulate, to study, to rehearse.

    The chessboard had been set long before the first move.

    In the early hours of May 10th, JF-17s lifted off under EMCON, flying low and fast. Briefly punching up to 40,000 ft inside Pakistani airspace, they released CM-400AKGs at optimal envelope. ECMs active, they dropped back to terrain-hugging altitude and RTB’d undetected.

    The CM-400AKGs soared high, grazing near-space before tipping into a Mach 4 terminal dive. Their passive seekers homed in on the 96L6E’s emissions Cheeseboard lit like a beacon. The S-400’s batteries came alive, but ECM fog blanketed the battlespace. Too slow. Too late.

    There was no dogfight.
    No radar jamming dance.
    Just raw, long-arm power projection.

    The Block IIs turn south, ECM pods chirping, mission complete.

    The message?
    You don’t need a 5th-gen fleet to break 5th-gen bubbles.
    What you need is the will to strike first, and the reach to make it hurt.

    Adampur's Growl was silenced,
    Giving PAF a corridor to operate if need be to target New Delhi.
    Silencing the Growl wasn’t just about a radar.
    It was about removing illusions.
    Pakistan doesn’t seek escalation.
    But it will rewrite the rules of engagement if needed.
    Swiftly. Surgically.
    At Mach 4.

    For Doval, there is a Kashmiri proverb:

    “Haal matte pricztam
    Royye sei wechtam”

    Ask me not the state of my affairs
    Look at my face and know what i am going through

    Destruction of S400 is huge; even bigger than the three Rafale jets. Pakistan’s military strikes were not cosmetic but strategic in nature which were aimed at crippling the nervous system of enemy.

    So this is being done without any backchannel or official talks with Pakistan, or via a third party interlocutor like the US, when Modi claims that there has been no ceasefire and the military operation is still on.

    Pause in India-Pak military action, Army works on plan to ‘rebalance’ troops at border | India News - The Indian Express

    https://indianexpress.com/article/india/to-dial-down-army-works-on-...

    A fortnight into the pause of military action in the wake of the April 22 Pahalgam terror attack, a proposed plan for “rebalancing of troops” is being discussed within the military to avoid any fresh escalation at the borders, The Indian Express has learned.

    This even as Operation Sindoor is on pause and all alerts remain at their heightened levels.

    While Indian and Pak armies are focusing on multiple confidence-building measures, plans for de-escalating troops and equipment from the borders within the next fortnight are being considered.

    Sources said Pakistan, which carried out major reinforcements of troops and equipment over the last few weeks, will also pull them back to pre-April locations.

    Incidentally, India had not ordered large-scale mobilisation or deployment of offensive formations over the last month. Limited equipment and corresponding troops, which had been moved from their permanent locations to operational ones, are now planning to go back to their regular locations.

    During Operation Sindoor, the density of troops along the borders had increased but that was more because of curtailing leave and less essential movement. However, sources said, these restrictions have now been lifted. Even short-term courses, which were to be cancelled temporarily, will now continue as per slated schedules.

    According to sources, after the first two days following the ceasefire agreement, no aerial violations by Pakistani drones were reported though the occasional stray drones were sighted in Jammu and Kashmir.

    They added that there are orders in place to avoid firing on them without appropriate clearances, even as any ceasefire violations at the LoC will be responded to by the troops.

    As Prime Minister Narendra Modi had flagged, in his address to the nation, Operation Sindoor is only on pause. This would imply that the military would continue to remain at a heightened state of alertness and operational readiness, while maintaining a strong defensive posture throughout.

    There has been no official statement from the government on whether there have been DGMO-level talks on the de-escalation after May 12.

    On May 12, DGMO Lieutenant General Rajiv Ghai spoke to his Pakistani counterpart Major General Kashif Abdullah – their second conversation since they agreed to stop all military action—during which it was agreed that both sides would consider immediate measures to ensure troop reduction from the borders and forward areas.

    Sources said that stopping aerial violations was also discussed in the meeting.

    An Army statement had also mentioned that issues related to continuing the commitment that both sides must not fire a single shot or initiate any aggressive and inimical action against each other were discussed in the talks.

    The Indian Express had earlier reported that within days following May 12, both sides were scheduled to exchange plans on the modalities of de-escalation of troops and equipment deployed along the borders.



    Two days after the May 12 talks, Pakistan’s Foreign Minister Ishaq Dar had claimed that Pakistan had agreed to extend the ceasefire with India until May 18 following DGMO-level talks between the two sides.

    Without commenting on whether the two sides spoke, the Indian Army said both sides will continue the confidence-building measures to reduce the alertness level. It clarified that there is no expiry date to the understanding reached between the two militaries on May 10 to “stop all firing and military action from land, air and sea.”
