AMCA: An Indian Fifth Generation Story; an update

Medium Combat Aircraft from 2009

The Advanced Medium Combat Aircraft, or AMCA, is an indigenous attempt to develop a fifth generation fighter aircraft, the most ambitious indigenous project to reshape the Indian Air Force (IAF). It was in 2008 when, for the first time, a plan to develop a twin engine "Medium Combat Aircraft" was publicly announced. That was a different era. Mirage 2000 and Jaguar were to be phased out by 2015. Two squadrons of Tejas Mk 1 were to be followed by only four squadrons of Tejas Mk 2. India was gearing up for the MMRCA (Medium Multi-role Combat Aircraft) to equip six squadrons. And talks with Russia just started regarding the FGFA.

The IAF approached ADA (Aeronautical Development Agency) for the development of a 20 ton platform with stealth features. Initially, an amount of Rs 90 crore was released for the preparation of the feasibility studies. The entire project cost at that time was estimated at $2 billion with the commencement of the first flight by 2017! The programme was to see two technology demonstrators followed by seven prototypes. It was expected to be powered by a new variant of the indigenous "Kaveri" engine developed by the GTRE (Gas Turbine Research Establishment). Even there was a plan of potential cooperation with Snecma. The project soon would be renamed as the “Next Generation Fighter Aircraft" and ultimately AMCA.

A five member team was set up in 2009, led by Ashish Kumar Ghosh. They were provided the operational requirements of the IAF by VCAS N.A.K. Browne. The first drift of a feasible configuration was completed by 2013. The first known model was named 3B-01, which was to be followed by eight more design configurations. The baseline configuration was improved with each successive model, culminating in improvements in stealth, aerodynamics, payload capacity, layout, controls and many others. Each model went through extensive studies and wind tunnel tests. When the 3B-09 came, there were significant changes in design, wings, air intakes, tails, weapon bays and vertical stabilisers. The 3B-09 would be further improved in the coming time to reach the final design much later.

ADA received draft Preliminary Services Qualitative Requirements (PSQRs) in September 2014. However, the next few years weren't much reportedly public, and MMRCA and FGFA stole the limelight. Ironically, none would be fruitful. While initially many were skeptical of India's capability to afford two different fifth generation fighter jet programmes simultaneously, after one point, AMCA became India's only resort to having fifth generation capability. An additional grant of Rs. 447 crore was sanctioned in 2018. A "Project Monitoring Team" was also formed to look after combat readiness and solve potential maintenance issues at the design level itself. During a press interaction in 2020, then CAS ACM RKS Bhadauria iterated the commitment of the IAF towards AMCA with the potential procurement of seven squadrons in multiple phases. The first two squadrons would be powered by the imported GE F414 (F414-GE-INS6) with a maximum output of 98 kN, while the rest will be powered by the indigenous engine with a higher output (at least 110 kN).

Not just a high output, but the new engine must have super cruise capability, which will allow it to have the supersonic flight without using the afterburner, which is crucial to sustain for a long time in the combat environment. ADA-GTRE is currently in discussion with multiple foreign OEMs (Rolls-Royce, General Electric and Safran) for the joint development. India aims for not just 100% transfer of technology but active participation in design and development and holds on to crucial knowledge of critical technologies like metallurgy as well.

In 2020, HAL took a ground breaking novel decision to include a private company, culminating in a three way partnership with HAL and ADA. Thus, AMCA onwards would progress as a public-private programme. The aim was to create a SPV (special purpose vehicle) as fast as possible with the participation of the private venture, which would be on equal financial and work terms with the public sector. The PDR (preliminary design review) was completed in 2022, followed by the completion of the CDR (comprehensive design review) in 2023. A nod was given for the formation of the SPV for the "manufacturing and production" of the aircraft. The year 2022 also witnessed the metal cutting of titanium bulkheads.

In early 2024, the CCS (Cabinet Committee on Security headed by the PM) approved and allocated Rs 15,000 crore for the development and manufacture of five prototypes. According to the original plan, ADA, DRDO and HAL, along with a selected private company, would build these prototypes. In mid-2024, a high-level meeting was conducted between DRDO and the IAF to discuss the further roadmap.

According to the latest reports, now there are some changes in approach. Now onwards, it will be a collaborative competition. In easy words, DRDO (ADA) will select two development-cum-production partners (DCPP) involving one public sector and one private sector entity. Thus, there will be two production lines, facilitating a quicker commencement of the project. Thus, it also reduces the risk of derailment if one production line hits the hiatus. However, India has yet to solve the engine issue. Amidst the Russia-Ukraine war, the continuous sanctions and counter sanctions have put the global supply chain at risk. Almost every major aircraft and engine OEM (original equipment manufacturer) is facing slow production rates.

As of July 2024, the contract between India and the US for the GE F-414 engine is yet to be signed. Besides, India has yet to select an OEM for the joint development of the indigenous engine necessary to power later series of AMCA. Though India is facing several challenges, work on AMCA is going on in full swing. In fact, with time, there are improvements to it. According to the latest news, the AMCA now has a maximum take-off weight (MTOW) of 27 tons with enhanced payload capability in the internal weapon bay. The first flight is now expected only by 2028 and anticipated to enter production by 2035.
