In the summer of 1986, then Group Captain Philip Rajkumar found himself spinning a British Aerospace Hawk at 40,000 feet over the Irish Sea. The aircraft entered what he later described as a “gentle corkscrew” — smooth, predictable, recoverable. Ideal for safely teaching young fighter pilots how to handle the margins of the flight envelope.
It would take another 22 years before the Hawk would enter Indian service.
This is the story of that delay. Of how a clear operational requirement was acknowledged, debated, evaluated, and then buried under indecision, political churn, and bureaucratic inertia. Of how a frontline interceptor — the MiG-21 — came to carry the burden of a trainer it was never designed to be. And of how that misfit cost the Indian Air Force not just aircraft, but lives.
The Crisis: An Unforgiving Gap (1960s-1980s)
From the 1950s until the early 1970s, the IAF operated a three-stage training model that was both structured and effective. Stage I flying was conducted on piston-engined trainers like the HT-2; Stage II progressed to the Harvard; and Stage III transitioned pilots to jet aircraft, notably the Vampire. For nearly two decades, this HT-2–Harvard–Vampire sequence formed the backbone of IAF pilot training.
But as the service modernised and trainer aircraft aged, this model began to falter. The MiG-21 had entered service in 1963. The HF-24 Marut followed, as did the Su-7 and, later, the Jaguar. Each of these aircraft pushed the envelope in speed, cockpit workload, and systems complexity. Meanwhile, the training aircraft remained stubbornly stuck in a previous generation.
The Vampires and Harvards were phased out by 1975. In their place, the HAL-built Kiran became the Stage II workhorse. It was rugged, easy to fly, and reliable — but never designed for stage III tactical instruction. To patch the growing gap, the IAF inducted the Polish TS-11 Iskra in 1975, creating what came to be known as an informal “Stage IIA.” The Iskra offered practical exposure to gunnery and other forms of weapon employment (euphemistically called ‘applied flying’), but it too had its limits. In 1976, a serious accident during a spin recovery exercise led to permanent restrictions on spinning. The aircraft was underpowered and could not credibly simulate the demands of high-speed tactical flight.
The Kiran fared better in handling, but not by much. Even the Mk II version, with improved engines, remained fundamentally underpowered. By the early 1980s, the gap between what the IAF’s trainers could offer and what frontline jets demanded had become unmanageable. Pilots were graduating from Stage IIA — Kirans and Iskras — and jumping straight into supersonic MiG-21s.
A Global Problem, a Global Solution: The Rise of the AJT
Across the world, air forces had already solved this problem. In 1949, Fokker of the Netherlands built the S.14 Machtrainer — one of the earliest dedicated jet trainers. The British followed with the Jet Provost in 1954, later succeeded by the Hawk. France and Germany developed the Alpha Jet in the 1960s as a modern twin-engine NATO trainer. In the United States, the supersonic T-38 Talon took to the skies in 1959 — the world’s first and most enduring high-performance trainer.
This new category — the Advanced Jet Trainer — soon became the global standard for preparing fighter pilots for the demands of frontline service. AJTs were designed to help trainees master aircraft at the outer edges of their operating envelope, particularly at high angles of attack and low-speed regimes, where loss of control is most likely to occur. To achieve this, AJTs were engineered with forgiving stall and spin characteristics, often featuring straight wings and carefully balanced inertia distribution. These aerodynamic choices made them ideal for teaching spin, stall, and recovery techniques — essential building blocks of combat proficiency. Their configuration also allowed for high sortie rates without imposing unsustainable wear on airframes or budgets. Crucially, AJTs helped build confidence in handling high-performance aircraft close to their control boundaries.
By the early 1980s, the world had long moved on to AJTs. The IAF had not.
The OCU as Stopgap: Making Do with Fighters
The IAF, like most professional air forces, operated dedicated Operational Conversion Units (OCUs) to convert pilots onto specific combat platforms. Canberra crews went through JBCU. Hunter pilots passed through OTU (later HOFTU). For the MiG-21 — the IAF’s most numerous fighter — the conversion was spread across front-line squadrons rotated through the MOFT (MiG Operational Flying Training) role.
From 1968 to 1977, squadrons such as No. 28, No. 30, and No. 8 moved to Tezpur to run MOFT courses. In 1986, these squadrons were consolidated into the MiG Operational Flying Training Unit (MOFTU), formally institutionalising what had until then been a workaround.
But there was a critical difference. While most air forces used AJTs as the final stage before entering OCUs, the IAF had no such buffer. Stage III no longer existed. The Vampire was gone. And so, HOFTU and MOFTU — flying Hunters and MiG-21s — became the de facto advanced jet training stage III.
The MiG-21, of course, was never meant to teach greenhorns. It was a 1960s supersonic interceptor, optimised for speed, altitude, and tight handling margins. Its two-seat trainer versions — the Type 66 and Type 69 — were imported in limited numbers, never locally produced, and nearing the end of their support life. Rear-cockpit visibility was constrained. Instructors lacked gunsights and often relied on visual references inside the cockpit to guide trainees through air-to-air and air-to-ground profiles. Its endurance barely touched 30–40 minutes, giving little room for remedial instruction. The MiG-21 trainer variant was unsuitable for pilots with only 150–200 hours of flying experience.
The statistics bear this out. Between 1986 and 1996, the Hunter-based HOFTU recorded only one Category-I accident linked to pilot error. MOFTU, operating MiG-21s in the same role, suffered sixteen — twelve of them due to pilot error. And once the Hunter was phased out, MOFTU carried the full weight of Stage III training.
The MiG-21 wasn’t just a difficult trainer. It was also expensive. Each sortie consumed four times the fuel of a modern AJT. Its tyres had to be replaced every 15–20 landings due to high-speed touchdowns, compared to five times that figure on AJTs. The brake pads lasted barely 100 sorties—again, far fewer than what AJTs could manage. The MiG-21 could fly no more than 40 minutes per sortie, while AJTs cruised for 90 minutes and could fly six sorties a day without overheating. The MiG required an imported nylon drag chute for landing, while the AJT did not.
And yet, the MiG-21 remained the IAF’s de facto AJT for nearly 30 years because there was nothing else.
Formal Recognition: The La Fontaine Committee (1982-1985)
The transition from subsonic trainers to frontline supersonic fighters had become a perilous leap, and long before accident data made headlines, the operational community was aware that the system was exhibiting alarming signs of fatigue.
In August 1982, the Government of India formally acknowledged this concern by appointing a Special Committee on Flight Safety (SCFS), chaired by Air Marshal La Fontaine. The committee undertook a detailed review of five years of human error accidents, examining training procedures, safety protocols, and systemic vulnerabilities.
The findings were unambiguous. The SCFS reported that the most repetitive accident pattern occurred during exercises involving high-performance aircraft manoeuvred near their control boundaries. Accidents often resulted when pilots failed to manage these margins or responded too slowly or inadequately. The committee also highlighted a deeper issue: that the conditioning process had been unable to produce pilots with the fine control responses and stress tolerance necessary to manage in-flight emergencies or unusual flight conditions close to the edge of the performance envelope.
The SCFS submitted forty-five recommendations. Barring two administrative recommendations, all were accepted by the government for implementation. The critical recommendation was what many in the IAF had long wanted: a dedicated Advanced Jet Trainer.
In March 1984, Air Headquarters issued Air Staff Target 204 (AST-204), formally defining the AJT requirement. The specification mandated an aircraft capable of safely demonstrating spins, stalls, and recovery procedures; conducting advanced aerobatics and tactical flying; operating economically in high-utilisation environments; and providing optimal cockpit visibility and ergonomics for instructional purposes.
The contrast with the MiG-21’s trainer capabilities could not have been starker.
Initial Indigenous Assessment and Global Search
The AST was submitted to Hindustan Aeronautics Limited for feasibility assessment. In September 1985, HAL concluded that indigenous development was not viable within acceptable timeframes due to existing commitments to the Light Combat Aircraft and Advanced Light Helicopter programmes. HAL recommended either extending the timeline by two years or partnering with a foreign design house. It also confirmed that no in-house AJT design was mature enough for immediate development.
With HAL effectively stepping back, Air Headquarters turned to the global market. By late 1985, the IAF had compiled an extensive list of candidates, both foreign and domestic. From abroad came the Franco-German Alpha Jet, the British Aerospace Hawk, the Italian SIAI-Marchetti S-211, the Spanish CASA C-101 Aviojet, the German MBB-339, and the Czech L-39 Albatros. Within India, HAL’s Kiran Mk II and the Ajeet Trainer were also evaluated to ensure that no viable indigenous option was overlooked.
The shortlisting moved swiftly. The S-211, CASA, L-39 and MBB-339 were ruled out early during paper assessments against the Air Staff Requirements (ASR). Key deficiencies were found in areas such as maximum speed, rate of climb, external load capacity, powered controls, and stall behaviour. The Ajeet Trainer, still lacking a production-ready prototype as late as 1987, was deemed too immature. While the Kiran remained a dependable workhorse, it lacked the performance and systems needed for stage-III training.
By early 1986, only two serious contenders remained. The British Aerospace Hawk and the Dassault-Dornier Alpha Jet. Both had been fielded extensively in NATO air forces. Both had proven track records.
Flight Trials: Istres and Dunsfold
In April 1986, a flight test team from the IAF was dispatched to evaluate both aircraft. The team included test pilots and engineers from ASTE, led by then Group Captain Philip Rajkumar. Among the team were Sqn Ldr Priya Ranjan Sharma, Flight Test Engineer Naresh Krishnan, and Dasgupta, representing the Directorate of Aircraft Projects.
The first stop was Istres, France — home of Alpha Jet evaluation. The aircraft impressed on performance. Twin engines, robust spin recovery, precise handling — Rajkumar would later describe its spin behaviour as “extraordinary.” But there were concerns. Rear-cockpit visibility was not ideal for instruction, and the SNECMA Larzac engine would necessitate India building an entirely new production line. Dassault proposed transferring its entire production line — lock, stock and barrel — to HAL in Bangalore.
Next, the team moved to Dunsfold, the historic Hawker airfield in Surrey, to evaluate the Hawk. Compared to the Alpha Jet, the Hawk’s spin characteristics were more pedestrian. But recovery was easy and stable. What stood out most was the superb rear cockpit visibility, thanks to its raised seating configuration. Moreover, the Hawk utilised the Adour 871 engine, a non-afterburning variant of the Adour 811 already in production at HAL for the Jaguar, resulting in approximately 70% parts commonality.
The team submitted its report on 1 June 1986. As Rajkumar later recalled, “there wasn’t much to choose between them” in training performance. Either aircraft could serve the IAF’s needs. The final decision, it seemed, would come down to industrial integration and cost.
The Ministry of Defence set 31 March 1987 as the deadline for selection.
The Bofors Bombshell and Its Aftermath
In April 1987, the Bofors artillery scandal significantly altered the defence procurement environment. The resignation of Minister of State for Defence Arun Singh, who had supported the AJT programme, and his replacement by Dr. Raja Ramanna coincided with a general suspension of major defence acquisitions.
Despite the changed environment, attempts were made to maintain programme momentum. In November 1987, a high-level meeting reduced the aircraft requirement from 94 to 78 units, while retaining the annual training capacity for pilots. Simultaneously, the Prime Minister’s Office encouraged exploration of Soviet alternatives under the Rupee Payment Arrangement.
The Soviet offer of modifying the MiG-21 trainer as an AJT was considered along with the trainer variants of MiG-29/Su-25 fighter aircraft. A paper study of the MiG-21bis was also carried out. However, none of these options satisfied the essential AJT requirements for fuel economy, maintenance simplicity, and safe spin demonstration capabilities.
Around this time, in 1988, the American company Northrop made an unsolicited offer to supply the TF-5, a two-seat trainer derived from the F-5 Freedom Fighter. Though not formally requested, this planted the seed for further American engagement and added another aircraft to an already crowded field.
The Committee Carousel
By 1990, the IAF had spent nearly four years waiting for political clarity. What followed was a bewildering succession of committees, each seemingly determined to start the evaluation process from scratch.
In June that year, the IAF presented a comprehensive briefing to the new Defence Minister, referencing previous approvals and reiterating the programme’s technical validation. However, the Defence Secretary recommended establishing a committee under the Scientific Adviser, Dr. V.S. Arunachalam, to conduct yet another comprehensive review, which was optimistically expected to take only one month to complete.
The Arunachalam Committee expanded the evaluation to include four aircraft: the modified MiG-21, the Northrop TF-5, the Dassault Alpha Jet, and the British Aerospace Hawk. This expansion necessitated additional assessment, including a 1991 visit by an IAF delegation to the United States. For the IAF, it would have been a Groundhog Day moment.
Air Marshal JK Seth (AOC-in-C, Training Command), AVM Sadanand (Commandant AFA), and Group Captain S. Bhojwani (A1 QFI) visited USAF training facilities. At AFB Luke AFB, Bhojwani and Sadanand flew sorties in the T-38 Talon, while Air Marshal Seth flew in the FT-5, a Navy-upgraded version with modern avionics and more efficient engines.
The T-38 demonstrated handling characteristics comparable to the MiG-21 Type 77, but with excellent rear-cockpit visibility and easier landing characteristics than the MiG-21 Type 69 trainer. The aircraft’s twin engines added safety, and its flight characteristics made it an appealing trainer platform at an attractive price. However, logistical complications emerged. The T-38 was a 1950s design. Northrop, like most Western aerospace firms, had stopped making many airframe components, which were once subcontracted to now-defunct vendors. Even the USAF and USN were struggling with spare parts. The team’s report did not recommend the FT5 as an AJT because its performance was similar to that of the MiG-21 trainer.
There was another twist. During one of the committee’s internal reviews, the DRDO unexpectedly presented what it called an “indigenous proposal” for the AJT. To the astonishment of those present, the proposal was a near copy of the Northrop TF-5 brief—a document the IAF had already received separately. When Air Marshal B.D. Jayal (then Deputy Chief of Air Staff) pointed this out, and the Scientific Adviser ended the meeting abruptly, complaining to the Chief of Air Staff. But at Air Headquarters, the games being played were already evident.
By April 1991, the committee reaffirmed that both the Hawk and Alpha Jet satisfied IAF requirements. Fresh Requests for Proposals were issued in February 1992 to both vendors, seeking technical and commercial proposals for three options: direct purchase, assembly from completely knocked-down kits with limited indigenous manufacture, and full indigenous production.
In May 1992, the IAF constituted a Technical Committee to examine the commercial terms. By September, both aircraft were found viable, and the committee recommended formal negotiations. In December, the Defence Ministry appointed yet another High-Level Expert Committee under the Scientific Adviser to the Defence Minister to vet the process.
In April 1993, this committee reconfirmed what had been evident since 1986: both aircraft met the IAF’s needs, and minor shortfalls could be overcome. Vendors extended their price validity till the end of the year, giving India time to finalise its decision.
New Players, Old Problems
With the Soviet Union’s collapse in 1991, Russia’s once state-controlled defence industry was now selling aggressively to survive. In 1994, the IAF received proposals for three developmental aircraft: the MiG-AT, Yak-130, and UTS-M. Each promised advanced avionics, twin engines, and modular cockpit configurations. The MiG-AT, powered by French Larzac engines, was the most advanced of these options. In March 1995, Russia formally offered twenty MiG-AT aircraft, with fifty additional units for license production in India. In April 1996, the Russians sent a commercial offer for the MiG-AT, which had just completed test flights.
However, none of the Russian aircraft had completed development or achieved operational status with any air force, creating uncertainty regarding delivery timelines and technical maturity.
Meanwhile, India’s own AJT procurement process had slowly gathered shape. In August 1993, the Cabinet formally cleared the programme. An Apex Body was formed under the Principal Secretary to the Prime Minister. A Negotiating Committee was constituted to engage with both British Aerospace and Dassault. The approved strength was 66 aircraft, with options for more. A Technical group headed by the Deputy Chief went into the feasibility of indigenous manufacturing. By September 1994, the government decided to go all in: the AJT would be manufactured in India.
HAL submitted a Detailed Project Report in March 1995, claiming that AJT production could be accomplished with minimal infrastructure upgrades. By February 1997, final commercial discussions had been completed with both vendors. A decision appeared close.
Then HAL did something no one expected.
The Indigenous Curveball
In 1998, HAL put forward an entirely new proposal — an indigenous design dubbed the HJT-37. It was meant to replace both the Kiran and MiG-21 in the training pipeline. The promise was tempting: a home-grown solution to a long-standing gap. However, there was no airframe, nor was there a prototype. HAL claimed it could be ready with the first aircraft in seven years. By contrast, BAe and Dassault had guaranteed full delivery within 77 months.
The HJT-37 proposal, though not inherently flawed, introduced yet another delay. It opened the door to fresh contenders. Offers arrived from Italy’s Aermacchi for the MB-339FD and the Czech Republic for the L-59. The IAF evaluated both on paper but found neither met the core requirements.
Meanwhile, avionics technology had advanced. Air Headquarters had been reviewing and updating the AJT’s avionics configuration to ensure it remained aligned with frontline platforms. The goal was to ensure cockpit commonality with the IAF’s evolving fleet, including upgraded MiG variants, the Su-30, Jaguar, and Mirage 2000. As a result, revised RFPs were issued in July 1999 to reflect these updated requirements and technological expectations.
Only British Aerospace responded by the deadline. To avoid a single-vendor procurement scenario, the Chief of Air Staff requested that the RFP be reissued. And so, the process returned to familiar territory: another reset.
The Kalam Committee and Final Resolution
The decisive factor in programme resolution was the 1997 committee led by Dr A.P.J. Abdul Kalam, which investigated persistent accident rates and training deficiencies. Like the La Fontaine Committee fifteen years earlier, it concluded that immediate AJT induction was essential.
By 2003, political conditions permitted a significant resumption of defence procurement. In March 2004, India contracted for the Hawk Mk. 132, with 24 aircraft manufactured in the United Kingdom and 66 produced under license at HAL. The first aircraft entered service in 2008, twenty-four years after the initial requirement was established.
Production difficulties persisted even after the contract was signed. In November 2010, Defence Minister A.K. Antony informed Parliament that HAL had failed to meet delivery schedules due to tooling issues, defective components, and vendor dependency problems.
The Cost of a 25-Year Delay
The saga of India’s AJT was never just about aircraft. It was about people. For nearly three decades, young IAF pilots were asked to bridge an impossible gap — from subsonic trainers to unforgiving supersonic fighters — with little more than raw courage and institutional improvisation. The MiG-21 continued to serve not because it was well-suited for training, but because there was nothing else available. The consequences were grave. India paid with coffins of scores of young, promising pilots.
Spin training had to be removed from Stage III flying altogether. “Spinnability,” once a non-negotiable requirement, was quietly downgraded to a “desirable feature” in the revised AJT specs of 1999. Ironically, in 2009, a CAG report critiqued the IAF for acquiring the Hawk “against an outdated Staff Requirement.”
And yet, the numbers told their truth. When the MiG-21 was finally removed from the Stage-III training role after 2008, accident rates in advanced training declined. The same pilots, flying the same sorties in Hawks, faced fewer risks. The operational requirement for an AJT had been justified all along. Only the decision had been delayed.
In those 25 years, the programme passed through four Defence Ministers, four Scientific Advisers, multiple Chiefs of Air Staff, and at least a dozen committees. The IAF tested aircraft across Europe and the United States. HAL proposed three different approaches over the years — including license production, design collaboration, and an indigenous design. Still, the case sat unresolved while young pilots paid the price.
Critics of the IAF have long argued that the crisis could have been mitigated through the use of better simulators, increased flying hours on Kirans and Iskra, or a more flexible syllabus. On the other hand, HAL has reflected on how the outcome might have changed had its 1985 suggestion — to delay timelines or partner with a foreign design house — been taken seriously.
And in fairness, both Air Headquarters and the Ministry of Defence were balancing risks of their own: diverting HAL might have impacted the LCA and ALH projects. Given HAL’s record at the time, delays were likely to occur. But the cost of doing nothing was higher still.
The Advanced Jet Trainer programme serves as a case study in defence procurement complexity, illustrating how operational requirements can be subordinated to institutional hesitation and how bureaucratic processes, despite multiple objective evaluations, can themselves become a source of operational risk and capability degradation.
No one was held accountable for the protracted intransigence, or for the avoidable loss of lives that many senior personnel, from La Fontaine to Kalam, had tried to prevent. The MiG-21, a capable interceptor in its own right, gained an undeserved reputation as a dangerous aircraft essentially because it was forced into a role for which it was never designed.
