The news

New Delhi. On the eve of the Indian Air Force’s 94th anniversary on October 8, Air Chief Marshal Amar Preet Singh, who retires this month, said the force is moving in the “right direction” but “can be a little faster”, needing “greater capacity, faster induction and more combat mass”, PTI reports. He said the IAF had shifted from a “platform-centric to capability-centric” approach, proven in Operation Sindoor, and flagged LCA Mk-1A delays. At his annual press conference on October 3 he put the force at 29 operational fighter squadrons against 42 authorised, as reported by Outlook. The Economic Times reports that GE Aerospace shipped four engine sets to HAL last month and HAL expects over 20 engines a year from 2027. Deliveries on a $700 million order for 99 F404 engines, due from 2024, slipped; sources told ET that penalties have been imposed on GE.

The chain in one line: MiG-21s retire faster than replacements arrive → squadrons fall to 29 against 42 → Tejas Mk-1A is held up by imported F404 engines → GE supplies stabilise after penalties → HAL seeks F414 technology transfer and India an engine of its own

Static syllabus linkage

  1. Defence Acquisition Procedure 2020 gives first preference to Indian-designed equipment. DAP 2020 lists acquisition categories in order of priority, with Buy (Indian-IDDM), meaning indigenously designed, developed and manufactured, at the top and Buy (Global) last. IDDM needs at least 50% indigenous content. The Defence Ministry also notifies Positive Indigenisation Lists of items that can no longer be imported after set dates; the first, in August 2020, had 101 items.
  2. Tejas is designed by ADA and built by HAL. The Light Combat Aircraft Tejas is designed by the Aeronautical Development Agency under the Defence Ministry’s Department of Defence Research and Development and manufactured by Hindustan Aeronautics Limited, a Defence PSU in Bengaluru. It flies on the American GE F404 engine; the Mk-2 is to use the more powerful GE F414.

Why UPSC loves this

  1. GS3 links security to indigenisation. The syllabus covers “Indigenization of technology and developing new technology”; a falling squadron count tests it directly.

Prelims nuggets

  • Under DAP 2020, Buy (Indian-IDDM) is the highest-priority acquisition category; IDDM stands for Indigenously Designed, Developed and Manufactured.
  • The Tejas Light Combat Aircraft is designed by the Aeronautical Development Agency and produced by Hindustan Aeronautics Limited.
  • The Indian Air Force was founded on October 8, 1932, which is observed as Air Force Day.
  • The Advanced Medium Combat Aircraft (AMCA) is India’s planned fifth-generation fighter.

Analysis

  1. The squadron gap is a production-rate problem. India can design a fighter; the difficulty is building enough each year. With old jets retiring, induction has to run faster than retirement just to stop the decline. That depends on HAL’s lines, its suppliers and, above all, engines arriving on time.
  2. Lens — Strategic autonomy and partnership: an Indian jet with a foreign heart is only half independent. The Tejas is Indian, but its delays came from a US engine maker’s supply chain, and the Mk-2 will also use a GE engine built under licence. A foreign supplier thus sets the pace. A thoughtful officer would accept licensed engines and a foreign multi-role fighter for now to keep the fleet strong, while funding an indigenous engine steadily for the long term.
  3. Buying abroad now and building at home later must not cancel each other. A large foreign multi-role fighter purchase closes the gap quickly but takes money and orders away from Indian programmes. The way out is to tie foreign purchases to local manufacture and to ensure firm, long-term orders for Tejas so HAL and private suppliers can invest.

Possible Mains question

India’s fighter squadron strength has fallen well below its sanctioned level. To what extent can indigenisation close the gap? (15 marks, 250 words)

Model approach

  1. Directive — To what extent. Judge how far indigenisation can go, with limits.
  2. Introduction — 29 squadrons against 42 authorised. Cite the Chief’s October 3 figure, as reported by Outlook.
  3. Body — retirements outpaced inductions. MiG-21 exits and Tejas Mk-1A engine delays. Draw a graph of retirements against inductions.
  4. Body — indigenisation works on design, not yet on engines or pace. Value addition: DAP 2020’s Buy (Indian-IDDM) priority; F404 delays.
  5. Conclusion — buy now, build steadily. Bridge purchases with local manufacture, assured Tejas orders and an engine mission.

Administrator's brainstorm

As Defence Production Secretary, how would you speed up fighter deliveries?

I would track engine and component supplies weekly with HAL and the engine maker and enforce penalties for delay. I would give HAL and its suppliers firm long-term orders so that they invest in capacity.
