EDITORIAL ANALYSIS – Let them take flight

The Editorial covers GS paper 3 : Indigenisation of technology and developing new technology

  • The Aero India 2019 air show and aviation exhibition held at Bengaluru marked two developments of significance :
    • Long awaited Final Operational Clearance of Light Combat Aircraft (LCA) Tejas Mark 1.
    • Unwelcoming report of DRDO to shelve the Kaveri turbo jet engine project

Why is India’s Aero potential stagnated by Political Myopia?

  • Historically, all major aerospace powers have possessed the capability to design airframes as well as power-plants. 
  • Until India can design and produce its own aero-engines, the performance and capabilities of any indigenously designed/built aircraft will be seriously limited by the technology that we are permitted to import.
  • India has already had two bitter experiences in this regard.  
  • The Hindustan Aeronautics Limited’s sleek and elegant HF-24 Marut fighter, of the 1960s and 1970s, failed to achieve its huge potential as a supersonic fighter for want of a suitable engine. 
  • Rather than exert itself to seek alternatives, the government of the day, with stunning myopia, closed the programme. 

What is the problem faced by Tejas?

  • Tejas was facing problem from lack of Engine thrust.
  • Even as the Kaveri has failed to make an appearance, U.S.-made alternatives such as the General Electric F-404 engine, or even the more powerful F-414, do not deliver adequate thrust for the Tejas Mk 1, to meet all its missions. 
  • For the Tejas Mk IA, Mk II, the LCA Navy, and other aircraft programmes such as the Advanced Medium Combat Aircraft, India will need turbo-jet engines of even greater thrust. 
  • Thus, it is vital for India to develop a family of homegrown jet engines to power indigenous combat aircraft as well as re-engine imported ones. 

Why Indigenous developments have meted with a failure?

  • Both Tejas and Kaveri have seen more than their share of headwinds and uncertainty — form key components of India’s technological aspirations.
  • Unless carefully guided, protected and nurtured, their failure could spell the end of India’s aeronautical industry, or condemn it forever to licensed production.
  • A long production run of, say, 250-300 aircraft for the Tejas and its advanced derivatives is essential if the industry is to hone its design and production skills.
  • The same holds good for the Kaveri, except that the design and production of a functional turbojet engine are even more challenging. 
  • Despite HAL’s claims to have manufactured 5,000 aero engines and 18,000 overhauls it has failed to imbibe aspects of design, metallurgy, thermodynamic and aerodynamic engineering as well as the complex tooling and machining process required for the design and manufacture of aero-engines, over the past 60 years — a sad commentary. 

What is the story of Kaveri?


  • In 1986, the DRDO’s decades-old Gas Turbine Research Establishment (GTRE) was tasked with developing an indigenous power plant for the LCA, which was to replace the U.S. engines being used for the development phase of the aircraft
  • Having developed two experimental engines, the GTRE took up a turbofan design, designated the GTX-35VS “Kaveri”, for the LCA. 
  • Full-scale development was authorised in 1989 for 17 prototypes at a cost of $55 million. 
  • The first complete prototype Kaveri began tests in 1996, and by 2004 it had flown on a Russian flying test-bed; albeit unsuccessfully.
  • Since then, the Kaveri has made sporadic progress and the GTRE has been struggling with serious design and performance issues which it has been unable to resolve.
  • As the Kaveri missed successive deadlines, the U.S. import option was mindlessly and gleefully resorted to.

What might be the possible reasons for this trend?

  • Lack of political leadership and willingness to risk
  • Neglect as well as absence of a vision for the aeronautical industry
  • Over estimation by the DRDO of its capabilities compounded by a reluctance to seek advice
  • Inadequate project management and decision-making skills of DRDO’s scientists
  • Exclusion of users — the military — from all aspects of the projects


  • It is still not too late for the government to declare both these projects as ‘national missions’ and initiate urgent remedial actions. 
  • The success of both the Kaveri and Tejas programmes will transform the aerospace scene, and put India in the front ranks of aeronautical nations, perhaps even ahead of China, if the desired degree of resolve and professional rigour can be brought to the fore.
  •  If we miss this opportunity, we will remain abjectly import-dependent forever in this vital area.
