India’s Fourth Air Force Incident in Four Months Sparks Alarm as Fighter Squadrons Fall to Crisis Levels

(DEFENCE SECURITY ASIA) — The Indian Air Force has suffered its fourth major aircraft incident within four months, exposing an increasingly dangerous intersection between shrinking squadron numbers, rising operational tempo, and delayed modernization across India’s combat aviation inventory.

The latest episode, involving a Su-30MKI that blocked Pune Airport after an apparent undercarriage failure, immediately transformed a routine runway emergency into a wider debate about India’s weakening two-front deterrence posture.

With only about 29 operational fighter squadrons available against an authorized requirement of 42, every damaged aircraft now carries disproportionate strategic significance for India’s airpower balance against Pakistan and China.

Indian Air Force officials described the Pune episode only as “an incident involving an IAF aircraft,” while emphasizing that crews were working rapidly to restore operations and minimize wider disruption.

That carefully restrained language followed three earlier incidents during 2026, including a microlight trainer force-landing, a damaged Tejas fighter, and a fatal Su-30MKI crash in Assam.

The pattern has intensified scrutiny because each incident has occurred while India remains trapped inside its deepest combat squadron deficit since the middle of the twentieth century.

The retirement of the last MiG-21 Bison squadrons during 2025 removed India’s oldest fighter force, yet replacement aircraft have not arrived quickly enough to prevent accelerating numerical erosion.

The result is an air force increasingly forced to sustain frontline readiness, pilot training, and strategic signaling with fewer aircraft, aging fleets, and mounting maintenance pressures.

The pressure is especially acute because India now faces simultaneous military competition across the Himalayan frontier, the Arabian Sea, and the wider Indo-Pacific maritime theater.

Chinese airpower expansion and deeper Pakistan-China military integration have increased the importance of maintaining high fighter availability, rapid sortie generation, and credible escalation dominance.

Yet the four incidents during 2026 suggest the Indian Air Force is being forced to operate with diminishing redundancy, shrinking logistical margins, and increasingly overstretched maintenance infrastructure.

That combination has transformed each individual accident from an isolated aviation mishap into a larger warning about India’s future ability to sustain prolonged air operations during a regional crisis.

The Fourth Incident That Brought Pune Airport to a Standstill

A Su-30MKI returning to Lohegaon Air Force Station on 17 April reportedly suffered a hard landing that triggered an undercarriage failure shortly after touching down.

The twin-engine fighter came to rest directly on the runway, forcing Pune Airport to suspend both military and civilian operations for more than nine hours.

The disruption rapidly expanded beyond a localized air force emergency because Pune functions simultaneously as a major Indian Air Force base and civilian aviation hub.

Night flights were diverted, commercial schedules collapsed, and heavy recovery equipment was eventually required to move the stranded aircraft from the runway.

Although the crew survived without injuries, the episode highlighted how a single technical failure can now create outsized operational consequences across India’s broader logistics network.

The Pune incident did not involve a mid-air crash, yet its strategic importance stemmed from exposing how limited redundancy now exists within India’s shrinking airpower infrastructure.

With fewer available combat aircraft and reduced squadron depth, even temporary losses increasingly disrupt training cycles, sortie generation, and regional force posture.

The Court of Inquiry ordered after the episode is expected to focus upon whether the failure originated from landing gear fatigue, maintenance shortcomings, or operational overstress.

Three Earlier Incidents Had Already Raised Alarm

The first incident occurred on 21 January when a two-seat Indian Air Force microlight trainer suffered an engine malfunction after departing Bamrauli Air Force Station.

The aircraft was conducting a routine training mission near Prayagraj when the crew lost confidence in the engine and executed an emergency landing.

The microlight eventually came down safely inside an uninhabited pond area behind KP College, preventing civilian casualties and limiting wider damage.

Both crew members survived after being assisted by local residents, while the Air Force immediately ordered a formal technical investigation.

The second incident involved a HAL Tejas Light Combat Aircraft during February, when the fighter reportedly overshot a runway after a suspected technical malfunction.

The pilot ejected safely, but the aircraft sustained extensive structural damage that effectively made it the third major Tejas loss since induction.

HAL publicly described the event as a relatively minor ground incident, although the damage reportedly forced the Indian Air Force to inspect its single-seat Tejas fleet.

The most serious accident occurred during March when a Su-30MKI from Jorhat Air Force Station crashed in Assam, killing both crew members.

The Su-30MKI Backbone Is Carrying Unsustainable Pressure

The March crash was particularly significant because the Su-30MKI forms the backbone of India’s fighter inventory, accounting for roughly fifteen operational squadrons.

India operates approximately 230 Su-30MKI aircraft, meaning the fleet represents the central pillar of Indian deterrence against both Pakistan and China.

Yet the March accident became the thirteenth known major Su-30MKI attrition incident since the type entered Indian Air Force service.

The two pilots, Squadron Leader Anuj and Flight Lieutenant Purvesh Duragkar, were killed after radar contact disappeared during a routine training mission.

That loss immediately amplified concerns because India cannot easily absorb repeated attrition across its most important heavy fighter fleet.

The Su-30MKI remains indispensable because it provides long-range interception, air superiority, maritime strike, and nuclear delivery capabilities across multiple theaters.

However, the fleet has also struggled historically with maintenance, serviceability, and the delayed implementation of the planned Super Sukhoi modernization program.

Only 84 aircraft have been approved formally for deep modernization, while broader upgrade plans remain delayed by procurement and budgetary constraints.

India’s Fighter Squadron Deficit Has Reached a Historic Low

India’s authorized fighter strength remains fixed at 42 squadrons because that figure has long been considered the minimum necessary for two-front deterrence.

By April 2026, however, the Indian Air Force is operating with approximately 29 fighter squadrons, far below that long-standing benchmark.

Some political commentary has cited an even lower figure of 27 squadrons, although most official and independent assessments estimate between 29 and 31.

Even the higher estimate nevertheless represents the lowest Indian fighter strength in decades and falls below levels maintained during 1965.

The deficit emerged gradually as older Soviet-era fleets retired faster than replacement aircraft entered operational service across the Indian Air Force.

The MiG-23, MiG-27, and finally the MiG-21 were withdrawn without sufficient new squadrons arriving to compensate numerically.

India now faces the prospect of additional retirements involving Jaguars, Mirage 2000s, MiG-29s, and eventually older Su-30MKI variants.

Unless replacements accelerate dramatically, the Indian Air Force could lose more than 250 combat aircraft during the next fifteen years.

Delayed Procurement Programs Are Deepening the Crisis

The Tejas Mk1A program was supposed to provide India’s fastest route toward rebuilding squadron numbers after the MiG-21 retirement.

India has ordered 180 Tejas Mk1A aircraft, theoretically enough to create around ten fighter squadrons during the coming decade.

However, deliveries remain approximately two years behind schedule because of engine shortages, integration problems, and wider supply chain disruption.

HAL has reportedly assembled several completed airframes, yet operational induction remains delayed pending Indian Air Force review and GE engine deliveries.

Even under optimistic conditions, HAL is expected to manufacture only between 16 and 24 fighters annually.

That production rate means the entire Tejas Mk1A order could require until approximately 2033 before becoming fully operational.

India has therefore attempted to pursue an additional 114 multirole fighters, most likely centered upon a larger Rafale acquisition.

Yet negotiations remain unresolved because India seeks greater technology transfer, source code access, and domestic production rights than France currently appears willing to provide.

Meanwhile, India’s planned future replacements remain too distant to stabilize force levels because the Tejas Mk2 has not yet flown and the AMCA stealth fighter is unlikely entering service before 2034.

That timeline creates a dangerous capability gap during the late 2020s, precisely when China continues expanding fighter production and Pakistan deepens integration between Chinese-origin aircraft, missiles, and airborne surveillance networks.

The Indian Air Force is therefore confronting simultaneous numerical decline, increasing maintenance burdens, and rising strategic demand across the Himalayan frontier, Arabian Sea, and Indian Ocean approaches.

Every additional accident now carries consequences extending beyond a single aircraft because India lacks sufficient reserve squadrons, spare airframes, and trained replacement crews to absorb repeated attrition.

The logistical burden is equally severe because older fleets require imported spare parts, complex maintenance cycles, and expensive overhauls that increasingly consume resources intended for modernization.

India’s planned acquisition of 114 additional fighters could eventually cost more than USD 20 billion, equivalent to approximately RM76 billion, yet negotiations remain politically and technically unresolved.

If procurement delays continue while additional Jaguars, Mirage 2000s, and MiG-29s approach retirement, Indian fighter strength could temporarily fall below 25 operational squadrons before recovery begins.

Such an outcome would fundamentally weaken India’s ability to sustain prolonged simultaneous air operations against Pakistan and China, undermining deterrence precisely when regional military competition continues accelerating.

The shortage also creates a cascading training crisis because fewer available aircraft force the Indian Air Force to reduce flying hours for younger pilots.

Reduced training opportunities can eventually produce a smaller pool of combat-ready aircrew precisely when India requires greater readiness across multiple operational theaters.

The problem is especially acute for conversion training because new Tejas and Su-30MKI pilots already require extensive simulator time and limited frontline aircraft availability.

As operational squadrons absorb greater pressure, commanders may increasingly prioritize border deployments and quick reaction alert missions over routine training sorties.

That trade-off preserves short-term readiness, yet it gradually increases long-term institutional risk because pilots accumulate fewer flying hours under controlled peacetime conditions.

The Indian Air Force also faces the possibility that recurring accidents could damage confidence in indigenous programs, particularly the delayed Tejas Mk1A fleet.

If further Tejas incidents occur before full operational induction, political pressure could intensify for larger foreign fighter purchases despite India’s long-standing “Make in India” strategy.

That would create a deeper strategic dilemma because India would remain dependent upon foreign engines, imported avionics, and external technology transfers while attempting to preserve national aerospace autonomy.
