How Indigenous Innovation Keeps India's Jaguars Airborne Amid Global Spare Parts Cease, MIDHANI and GTRE Played Crucial Role

The Indian Air Force (IAF) continues to operate its fleet of SEPECAT Jaguar attack aircraft, a testament to the dedication and ingenuity of Indian engineers and institutions. Despite the aircraft's age and the global discontinuation of spare parts, the IAF, in collaboration with organizations like MIDHANI, GTRE, and HAL, has managed to keep these vital assets operational.

MIDHANI, a leading Indian materials science organization, plays a crucial role in this endeavor. They have successfully produced critical components for the Jaguar's Adour Mk 102 engines, such as high-pressure compressor (HPC) disc forgings. These forgings, essential for engine performance, are manufactured using advanced isothermal forging technology developed in partnership with the Defence Metallurgical Research Laboratory (DMRL). This ensures the components meet the demanding standards of military aviation.

GTRE, a research and development establishment specializing in gas turbine technology, provides crucial support for the Adour engines. While their primary focus is on developing indigenous engines for new aircraft, their expertise has been invaluable in reverse-engineering and redesigning components for the Jaguar that are no longer commercially available. This includes crucial testing and technical support, ensuring the continued efficiency and airworthiness of the IAF's Jaguar fleet.

HAL, the primary manufacturer and maintainer of the Jaguar in India, brings together the efforts of MIDHANI and GTRE. They oversee the overhaul, repair, and upgrade of the Adour engines, overcoming the challenge of discontinued parts by utilizing MIDHANI's material supply and GTRE's technical expertise. HAL's specialized facilities ensure that the intricate Adour engines continue to meet operational standards despite decades of service.

The continued operation of the Jaguar fleet is a remarkable achievement in the face of obsolescence. By leveraging indigenous capabilities in materials science, engine technology, and aircraft maintenance, India has not only maintained a vital component of its air power but also demonstrated its self-reliance in defense technology. This collaborative effort ensures that the IAF's Jaguars can continue to contribute to national security.

MIDHANI can also contribute to the Kaveri 2 version for developing 85 to 90 kN thrust for the Tejas MK1A engine.

In a few years time, IAF will also be the only airforce to be operating last active fleet of Mig-21.

Experience with keeping Jaguar flying will come in handy then also.

Some legacy you know.

Jaguar is a cutting-edge aircraft, and Bharat needs them. Great work done by Midhani to keep them flying. I hope these keep flying safely for years to come.

If there was ever a 3-legged cheetah that the IAF acquired, it is truly the Jaguar!

It has 4 hardpoints under the wing, of which two are needed for drop tanks, and 2 hardpoints on top of the wings are needed for WVR AAMs! Which leaves 2 hardpoints to carry any ground attack armaments! So what exactly can this aircraft do? If it was so great, why was it never used for bombing missions in the Kargil war and used only in a reconnaissance role?

For the amount of money that has been spent on DARIN 1/2/3 upgrades, you might as well have revived the HF-24 and re-engined it to be supersonic speed capable...

Jaguar was a useful enough jet during the Cold War, as it provided low-altitude flight performance coupled with tactical bombing roles of the time. Plus, it was required during the early stages of India's nuclear program, as it was certified to carry nukes (alongside the Mirage) when the country lacked any ballistic missiles.

Also, as India wanted to balance ties with the USSR and the West, it often ordered duplicate jets from both Europe and the USSR to meet similar requirements.

Jaguar's numbers and usage ratio are certainly nothing to write home about (just like the IAF's old Avro transport fleet), as you have noted. But its role was steadily diminished following the development of sophisticated AD systems by Pakistan/China, advancing long-range smart munitions, and its nuclear delivery role being overshadowed by India's advancing ballistic missile program.

As for Marut, it was somewhat prematurely retired. But since a powerful enough engine was never purchased to power it, and since capable Soviet jets (for the time) with attractive price tags were always readily available to the IAF, its fate was always sealed.

HAL MIDANI and GTRE and some private companies have collective responsibility to help in solving material process machining and indigenising spareparts of aeroengine and aircraft which ate not available from OEM.
We must encourage private companies for this specially for Jaguar Mirage and Su30 aircraft to remain flying.
