(DEFENCE SECURITY ASIA) — India and Japan are preparing for Veer Guardian 2026 as recovered Chinese PL-15E missile technology casts an unusually consequential intelligence dimension over an exercise officially focused on air combat, interoperability and tactical cooperation.

Scheduled for September 9–21 at Air Force Station Jodhpur in Rajasthan, the bilateral exercise places Japanese combat aircraft on Indian territory for the first time, expanding a defence relationship increasingly shaped by shared Indo-Pacific security pressures.

Japan will deploy three Mitsubishi F-2A multirole fighters from the 8th Air Wing at Tsuiki Air Base alongside approximately 110 personnel, creating a compact but strategically significant expeditionary force package for the unprecedented deployment.

The Japanese fighters will travel approximately 5,600 kilometres through Naha Air Base in Okinawa and Thailand with United States tanker support, making logistics, aerial refuelling and long-distance force projection important operational dimensions of Veer Guardian 2026.

Indian participants remain officially undisclosed, although Su-30MKI fighters are expected after their participation in the 2023 exercise, potentially creating another dissimilar air combat environment involving platforms developed around substantially different aerodynamic, sensor and weapons philosophies.

Yet the exercise carries a deeper potential significance because India recovered components from Chinese PL-15E beyond-visual-range air-to-air missiles following the intense India-Pakistan confrontation of May 2025, providing hardware potentially valuable for electronic warfare threat characterisation.

Indian examination reportedly included PL-15E seeker characteristics, electronic signatures, datalink behaviour, guidance architecture and electronic counter-countermeasure mechanisms, potentially transforming previously estimated Chinese missile parameters into measurable information usable for threat-library development and defensive programming.

That distinction matters because modern beyond-visual-range warfare increasingly depends upon identifying hostile radar emissions, disrupting missile-aircraft datalinks, manipulating terminal seekers and generating sufficiently accurate electronic-order-of-battle information before an adversary can complete its engagement sequence.

Japan faces the same broader Chinese missile family across the East China Sea and potentially around Taiwan, where PL-15-equipped J-20 and J-16 fighters could threaten Japanese combat aircraft and supporting high-value airborne assets during a regional confrontation.

No official Indian or Japanese announcement identifies PL-15E intelligence exchange as an objective of Veer Guardian 2026, making claims that classified missile data will be transferred speculative rather than an established component of the bilateral exercise.

Nevertheless, the convergence between recovered Chinese missile technology, reported Indian electronic-warfare upgrades and Japan’s unprecedented fighter deployment creates strategic relevance because both air forces confront increasingly sophisticated Chinese long-range air-combat capabilities across different Indo-Pacific theatres.

Veer Guardian therefore extends beyond individual dogfighting sorties by demonstrating expeditionary logistics, coalition interoperability and strategic signalling between two Quad partners whose evolving defence relationship increasingly intersects with China’s expanding aerospace, missile and electronic-warfare capabilities.

PL-15E Recovery Turns a Combat Threat Into an Intelligence Opportunity

The intelligence opportunity emerged from the May 2025 India-Pakistan confrontation, when intense beyond-visual-range engagements reportedly involved Pakistani J-10C fighters employing Chinese PL-15E missiles against Indian aircraft during one of South Asia’s largest modern aerial battles.

Pakistan claimed several Indian fighters were destroyed, including Rafales, while India subsequently acknowledged aircraft losses without accepting Pakistani totals, leaving important questions surrounding engagement geometry, electronic warfare, targeting chains and individual missile effectiveness unresolved.

For India, however, PL-15E missiles or major components landing inside its territory created an intelligence opportunity independent of competing victory narratives because physical hardware permits technical measurements that cannot reliably be obtained through remote observation alone.

Reports describe approximately six to eight recovered missiles or major sections, including at least one or two examples retaining substantial portions of their seeker, guidance electronics, datalink hardware and propulsion components for laboratory examination.

The recovered material reportedly reached India’s Composite Battle Response and Analysis Group and defence laboratories, allowing specialists to assess missile behaviour, seeker electronics and combat performance while examining components under controlled technical conditions.

Particular attention reportedly focused on the PL-15E active electronically scanned array seeker, including operating frequencies, transmit-receive architecture, scan patterns, beam steering, waveform agility and frequency-hopping behaviour relevant to electronic counter-countermeasures.

Engineers were also reported to have examined mid-course guidance and datalink characteristics, potentially revealing how targeting updates reach the missile before autonomous terminal homing and how communications resist disruption during a beyond-visual-range engagement.

Such information would not automatically expose encrypted software, source code or every guidance algorithm, because modern missile electronics can incorporate protected memory and security mechanisms specifically designed to limit exploitation following battlefield recovery.

Even incomplete technical exploitation can nevertheless carry substantial military value because measured emissions and hardware characteristics allow electronic-warfare engineers to replace assumptions with more accurate threat parameters when programming warning receivers, jammers and countermeasure systems.

The strategic consequence is therefore not that India necessarily “decoded” the PL-15E completely, but that physical recovery potentially narrowed uncertainty surrounding a weapon central to Chinese-origin beyond-visual-range air-combat doctrine across Asia.

Electronic Warfare Could Become the PL-15E’s Most Important Battlefield Legacy

Reports indicate electronic signatures derived from recovered PL-15E components were incorporated into Indian electronic-warfare threat libraries, potentially strengthening detection, classification and countermeasure responses across several frontline fighter fleets facing Chinese-origin missile threats.

The reported upgrades involved indigenous electronic-warfare systems associated with Tejas Mk1A, self-protection capabilities linked to upgraded Su-30MKI aircraft and the Rafale’s SPECTRA defensive suite, although the precise modifications remain officially unconfirmed.

If accurate, improved threat libraries could provide earlier recognition of PL-15E seeker emissions, allowing pilots and defensive systems additional time to classify an incoming threat, alter geometry and employ electronic or kinetic countermeasures.

Knowledge of datalink frequencies and update behaviour could prove particularly important because long-range missiles depend heavily upon mid-course information to refine intercept geometry before their onboard seekers acquire manoeuvring targets during terminal engagement.

Disrupting that chain could force a missile to rely upon degraded targeting information, increasing the importance of manoeuvre, jamming, decoys and emission management as defenders attempt to break the weapon’s engagement sequence.

Understanding frequency hopping, waveform agility and seeker behaviour could similarly improve jammer programming, although successful laboratory characterisation does not guarantee reliable operational defeat against missiles operating under changing geometry, electronic attack and networked targeting conditions.

The distinction is strategically important because electronic warfare is an iterative competition in which countermeasures produce counter-countermeasures, meaning any advantage generated through PL-15E exploitation could eventually stimulate modifications to Chinese missile software, waveforms or tactics.

China’s domestic PL-15 variants also cannot automatically be treated as technically identical to the export PL-15E, limiting conclusions that intelligence extracted from Pakistani weapons would completely neutralise missiles fielded by China’s People’s Liberation Army Air Force.

Nevertheless, accurate knowledge of one operational member of the missile family could strengthen modelling, simulation and tactical development, particularly when combined with intelligence collected from radar warning receivers, airborne sensors and combat engagements.

India’s potential advantage therefore lies less in possessing a universal PL-15 countermeasure than in reducing uncertainty surrounding a major BVR threat and converting battlefield recovery into electronic-warfare preparation for subsequent encounters.

Japan Has Powerful Reasons to Study India’s PL-15E Experience

Japan’s interest in India’s experience would be strategically understandable because Japanese combat aircraft operate near Chinese J-20 and J-16 fighters capable of carrying long-range air-to-air missiles designed to extend engagement distances across contested airspace.

The East China Sea creates demanding operational conditions where Japanese fighters could confront Chinese aircraft supported by airborne early-warning systems, networked sensors and increasingly long-range weapons, making missile threat characterisation central to survivability and tactical planning.

PL-15-family weapons potentially affect more than fighter-versus-fighter combat because long-range missiles can complicate operations by airborne early-warning aircraft, tankers and other high-value support platforms whose survival underpins sustained air operations.

For Japan, access to measured characteristics from missiles exposed to real combat conditions could therefore complement intelligence obtained through electronic surveillance, simulations and encounters with Chinese aircraft operating around Japan’s southwestern approaches.

No evidence establishes that India will provide classified PL-15E technical data during Veer Guardian 2026, and the exercise’s publicly declared objectives remain tactical training, interoperability, mutual understanding and strengthening bilateral defence cooperation.

However, military exercises create institutional relationships between pilots, planners and technical communities, providing opportunities to compare operational lessons even when sensitive intelligence remains compartmentalised and outside the formal scenario or publicly disclosed training objectives.

The timing is consequently notable because Japan’s first fighter deployment to India follows the 2025 missile recoveries and subsequent reports of Indian electronic-warfare modifications, although temporal proximity alone cannot establish an intelligence-transfer arrangement.

Veer Guardian can still strengthen Japanese preparedness through dissimilar air-combat training against Indian aircraft whose operational doctrine has been shaped by direct exposure to Chinese-origin fighters, missiles, drones and air-defence systems.

India similarly gains experience against Japan’s F-2A, a distinctive F-16-derived multirole platform, while observing how a technologically advanced partner structures expeditionary fighter operations, mission planning and logistics across a long-distance deployment.

The resulting exchange matters strategically because India and Japan occupy different geographic fronts of the Indo-Pacific security environment but increasingly confront overlapping challenges involving Chinese aerospace power, long-range precision weapons and network-centric warfare.

A 5,600-Kilometre Deployment Tests More Than Fighter Tactics

Japan’s approximately 5,600-kilometre deployment from Tsuiki through Okinawa and Thailand demonstrates the logistical architecture required to reposition combat airpower across the Indo-Pacific, where distance remains one of the decisive constraints on coalition operations.

United States tanker support adds another operational layer by demonstrating how aerial refuelling enables dispersed allied fighter movements, extending tactical aviation beyond national basing networks and connecting geographically separated partners through shared logistics infrastructure.

The transit therefore tests planning, maintenance, ground support, refuelling coordination and multinational access arrangements that become critical when aircraft must move rapidly between Northeast Asia, Southeast Asian staging points and the Indian Ocean region.

Such movements have strategic signalling value because combat credibility depends not simply upon fighter inventories but upon the ability to deploy aircraft, personnel, spares and support equipment across thousands of kilometres while sustaining operational readiness.

Japan’s deployment also follows expanding India-Japan discussions involving maritime security cooperation, equipment transfers, ship repair and an Indo-Pacific logistics network, placing Veer Guardian within a broader architecture of bilateral defence connectivity.

For India, hosting Japanese fighters demonstrates that Jodhpur can support foreign tactical aviation during sophisticated bilateral training, strengthening experience in reception, integration and sustainment of partner forces under an increasingly networked regional security framework.

For Japan, operating from Indian soil expands institutional familiarity with South Asian airspace, infrastructure and procedures, knowledge potentially valuable for future exercises or contingency cooperation extending beyond Japan’s traditional Northeast Asian operating environment.

The deployment remains modest at three F-2A fighters and approximately 110 personnel, meaning it should not be interpreted as a major force-posture shift or evidence of an emerging permanent Japanese combat presence in India.

Its significance instead lies in demonstrating repeatable access and interoperability, because small deployments can establish procedures and relationships that permit larger or more complex force packages should political and operational requirements evolve.

Veer Guardian consequently links tactical fighter training with strategic mobility, illustrating how Indo-Pacific airpower increasingly depends upon logistics networks, tanker availability, partner access and dispersed operating locations as much as individual aircraft performance.

Veer Guardian Signals a Wider India-Japan Indo-Pacific Alignment

The exercise builds upon Veer Guardian 2023, when India deployed four Su-30MKIs, two C-17 transports and an Il-78 tanker to Japan, making the 2026 deployment a reciprocal step in increasingly institutionalised air-force cooperation.

That earlier deployment already demonstrated India’s ability to project fighters into Northeast Asia, while Japan’s reciprocal mission now connects both air forces through practical experience operating from each other’s national infrastructure and training environments.

The broader political framework includes the India-Japan Special Strategic and Global Partnership and their participation in the Quad, where both governments publicly support a Free and Open Indo-Pacific amid intensifying regional military competition.

Recent bilateral discussions covering maritime security, equipment transfers, ship repair and logistics further indicate that fighter exercises are developing alongside wider defence-industrial and operational cooperation rather than functioning as isolated ceremonial engagements.

China remains an unavoidable strategic context because both countries monitor increasingly capable Chinese air, naval and missile forces, although Veer Guardian is officially bilateral training and should not automatically be characterised as an explicitly anti-China exercise.

The PL-15E dimension reinforces that complexity because India’s recovered missile hardware originated from combat with Pakistan, yet its potential intelligence relevance extends toward China because the weapon belongs to a broader Chinese air-to-air missile technology ecosystem.

Any eventual India-Japan discussion of measured seeker signatures or missile behaviour would therefore illustrate how battlefield intelligence generated in South Asia could acquire operational relevance thousands of kilometres away across the East China Sea and Western Pacific.

Yet claims of comprehensive PL-15E decoding, decisive countermeasures or technology transfer into India’s Astra Mk-2 remain unverified, requiring analytical caution before translating reported laboratory achievements into assumptions of battlefield superiority.

What can be established is strategically important enough: India possesses recovered Chinese-origin missile material, Japan faces related missile threats, and both countries are expanding fighter interoperability, logistics cooperation and defence engagement across the Indo-Pacific.

Veer Guardian 2026 therefore represents more than another bilateral exercise, because it connects combat lessons, electronic warfare, expeditionary logistics and strategic alignment within an Indo-Pacific battlespace increasingly defined by long-range missiles, networked sensors and contested information superiority.
