The process for obtaining Cabinet Committee on Security’s (CCS) approval for design and prototype development of Advanced Medium Combat Aircraft (AMCA) has been initiated.
The AMCA will be the first fifth-generation fighter used by the Indian Air Force (IAF). This fighter will provide many advanced and futuristic technologies to the IAF.
Hindustan Aeronautics Ltd (HAL), Aeronautical Development Agency (ADA), and Defence Research and Development Organization (DRDO) are jointly developing AMCA for the needs of the IAF.
The Necessity
The AMCA project is critical for IAF, which is grappling with just 30-32 fighter squadrons and will not reach its sanctioned strength of 42 squadrons even with “planned inductions” over the next 10-15 years.
The IAF needs the AMCA for the following reasons:
• Most of the fighter aircraft of IAF are fourth generation fighters. IAF currently does not operate any fifth-generation fighter aircraft. Leading military powers of the world have either already developed their fifth-generation jets or are in the advanced stage of their development. The US has F-22 Raptor and F-35, Russia has developed Su-57. China has developed J-20. It is imperative for India to go for a fifth-generation fighter jet when its adversary China has it.
• China’s fifth-generation fighter J-20 entered into service in 2017. Till now at least 40 units have been manufactured. As per reports, China may have around 200 of them by 2027. This is a serious concern for India. If a new more powerful engine is developed, the J-20 will achieve its full potential and become a major headache for India.
• Fifth-generation fighters offer a full spectrum of new technologies that are not there in fourth generation jets. These are stealth, supercruise, etc. Also, many futuristic technologies like Directed Energy Weapons, Flyby Optics can operate at their best in these fifth-generation fighter jets.
• An indigenous platform is the most logical decision. There are very few options available for import. The USA is not likely to offer such a platform to India as it has not yet given them to many of its closest allies. Procuring and operating the F-35 is already an economic burden for US air force itself. IAF cannot afford it. The F-35 is much bigger and heavier. But, the AMCA’s technology and capabilities will be at par with any other fifth-generation fighter in the world.
• India was working with Russia on the fifth-generation fighter aircraft (FGFA) project. But it pulled back due to many issues like pricing and transfer of technology. Cost is a major issue while procuring foreign platforms. There are limitations on integrating indigenous weapons and technologies with foreign platforms.
Development of AMCA So Far
The programme was earlier known as Medium Combat Aircraft (MCA). It was re-framed in 2010 with its name as AMCA. The basic design configuration was finalized in 2015. In 2018, the defence minister declared that the feasibility study had been completed. It was also decided to complete this project in two phases. The detailed design phase of AMCA started in 2018. The process for government approval of the next phase has been initiated.
Expected Timeline
AMCA will be developed in 2 phases. They are called AMCA Mk1 and AMCA Mk2. AMCA Mk1 will be a fifth-generation fighter aircraft and AMCA Mk2 will be more advanced with some features of sixth-generation fighter aircraft. AMCA Mk1 will be rolled out by 2024. Its first flight is expected in 2025. The induction in service may start from 2030. It may take another 10 years for the development of AMCA Mk2. A more realistic timeframe for the AMCA induction to kick-off, however, would be around 2035.
AMCA Numbers
It is expected that IAF will order 40 AMCA Mk1 and 80 Mk2. Thus, IAF is currently looking for total of 120 fifth-generation stealthy fighters. The AMCA is expected to replace Su-30 MKI in the future. But IAF operates over 272 Su-30s. With the AMCA’s induction, the fourth-generation fighters with their upgraded versions will continue to play a major role in the coming years.
Costs
Fifth Generation fighter aircraft, due to very special features, are costlier than fourth generation fighter aircraft. Since AMCA is an indigenous Fifth Generation aircraft, it is less costlier than similar aircraft available outside.
The maintenance costs are high. No country can acquire costly niche capability in large numbers. The IAF has conceptualised its need for only seven squadrons of the AMCA (including the Mark-2 version). Maintaining the stealth features makes the aircraft more expensive.
As of now, the development cost of the 25-tonne AMCA is estimated to be around Rs 15,000 crore.
Learning from Tejas Experience
The Aeronautical Development Agency and other academic institutions together developed the stealth technology. Getting stealth material was another challenge. After years of dedicated work, the team managed to overcome those challenges.
Tejas LCA was the country’s first venture into 4.5-generation combat aircraft. Nobody was ready to share knowledge. All core technologies were developed indigenously. All stakeholders have to be involved right from the beginning. Maintenance, ground support equipment, etc, have to be factored in along with proving the technologies and flying capability.
The AMCA is designed for future upgrades as its architecture allows it to incorporate new systems easily. Its basic airframe is stealth- and future-friendly.
Normally, the shelf life of an aircraft is 30 years, and the AMCA is designed to take care of upgrades for that period.
The AMCA can be teamed up with unmanned assets. There will be more unmanned assets with manned fighters controlling them.
Features
The detailed AMCA designing, which was sanctioned in December 2018, meets IAF’s “preliminary staff qualitative requirements” but the requisite powerful engine remains a major problem.
The AMCA will be available in stealth and non-stealth variants. The first two squadrons of AMCA Mark-1 will have the existing General Electric-414 afterburning turbofan engine in the 98 Kilonewton thrust class, while the next five mark-2 squadrons will have a more powerful 110 Kilonewton engine.
The advanced stealth features in the swing-role AMCA will range from “serpentine air-intake” and an internal bay for smart weapons to radar absorbing materials and conformal antenna.
The fighter will also have the supercruise capability to achieve supersonic cruise speeds without the use of afterburners as well as data fusion and multi-sensor integration with AESA (active electronically scanned array) radars.
The AMCA is envisioned as a twin-engine stealth aircraft with an internal weapons bay and Diverter-less Supersonic Intake, which has been produced for the first time and for which the design is now complete.
It will be a 25-tonne aircraft with an internal payload of 1,500 kg and an exterior payload of 5,500 kg in addition to 6,500 kg of internal fuel.
India and France are nearing a deal to collaborate on the development of a 125kN engine for the Advanced Medium Combat Aircraft (AMCA). DRDO and Safran are expected to jointly produce the advanced AMCA engine.
Safran and HAL already collaborate on the Shakti engine, which powers the indigenous Advanced Light Helicopter Dhruv and its variants, thus a future deal for AMCA engine between the two could be expected to be smooth.
Interim Plans
In the interim, IAF’s planned inductions include 73 Tejas Mark-1A fighters and 10 trainers, which will be delivered in the 2024-2028 timeframe under the Rs 46,898 crore deal inked with Hindustan Aeronautics in February this year. Then there is the long-pending “Make in India” project for 114 new 4.5-generation fighters with “some fifth-generation capabilities” for over Rs 1.25 lakh crore, which has seven foreign contenders and is likely to get the initial “acceptance of necessity” next year.
There are some discussions also underway about whether India should leapfrog from the Tejas Mark-1A directly to the AMCA.
Testing Technology
DRDO, in March 2022, a DRDO announcemen said, “Based on the design by ADA & DRDO, the fabrication of leading edge of AMCA initiated at HAL with special material for 5th gen design. The unit will undergo structural & other testing before putting it on the first prototype. An imp milestone for AMCA.”
Special Purpose Vehicle
In February 2022, R Madhavan, chairman of HAL had said that the company was employing a special purpose vehicle (SPV) model with private partners to produce the next-generation AMCA and Indian Multi-Role Helicopter (IMRH).
The progress in the AMCA program would mark a major shift for India which stares as a shortage of combat aircraft against the requisite strength along with an aggressive neighbour at its doorstep.
