In so far as the Su30 and its engines are concerned, HAL was doing more than just assembling CKD kits. The contract with Russia provided for progression in the kind of work done at HAL, with HAL initially only assembling CKD kits but later on progressing towards full manufacture from raw material stage. However, in doing so, HAL was contractually bound to import all the raw materials from Russia. I suspect the contract for MiG 21 must have contained similar restrictions.
Here's what defence writer Col. Ajai Shukla wrote on the subject in 2015: Quote:
How “Make in India” plays out is evident from the Sukhoi-30MKI assembly line in Nashik, where Hindustan Aeronautics Ltd (HAL) builds the air force’s frontline fighter. While negotiating the contract for 180 Su-30MKIs in the year 2000 (which later went up to 272 fighters) India --- the world’s largest operator of this aircraft --- employed all the leverage it had to extract technology from Russia. Even so, just 51 per cent of the fighter (by cost) is made in India. Russia insisted that all raw material --- including 5,800 titanium blocks and forgings, aluminium and steel plates, etc. --- be sourced from that country. Similarly, HAL builds the fighter’s giant AL-31FP engines in Koraput, Odisha, but is bound by the contract to import 47 per cent of the engine (by cost), including high-tech composites and special alloys --- crucial secrets that Russia will not part with.

Earlier, he had written: Quote:
Business Standard spoke to HAL officials to find out why prices have risen despite an ongoing indigenisation programme that has met all its targets. The reason, it emerges, lies in the nature of the manufacturing contract signed with Sukhoi, which was to see a progressive enhancement of Indian content through four phases. Yet, even though Phase IV has recently been achieved, this provides for only limited indigenization. While Sukhoi was bound to transfer technology for building the fighter, the contract mandates that all raw materials --- including titanium blocks and forgings, aluminium and steel plates, etc --- must be sourced from Russia.
This means that, of the 43,000 items that go into the Sukhoi-30MKI, some 5,800 consist of large metal plates, castings and forgings that must contractually be provided by Russia. HAL then transforms the raw material into aircraft components, using the manufacturing technology transferred by Sukhoi.
That results in massive wastage of metal. For example, a 486 kilogramme titanium bar supplied by Russia is whittled down to a 15.9 kg tail component. The titanium shaved off is wasted. Similarly a wing bracket that weighs just 3.1 kg has to be fashioned from a titanium forging that weighs 27 kg.

HAL being a commercial organization, the economic viability of manufacturing locally is also required to be factored in. Quote:
“For raw materials production to be commercially viable, India’s aerospace companies would need to produce in larger volumes. That means they must become global suppliers, as a part of a major aerospace company’s global supply chain. Licensed manufacture for our own needs does not create adequate demand,” says Daljeet Singh, HAL Nashik’s manufacturing head.

While China has been successfully reverse engineering Russian-origin military planes and their engines, we have made no such attempts, out of fear of displeasing the Russians. The costs involved in undertaking massive reverse engineering of complex items must also be a deterrent I'm sure, given how our Finance Ministry behaves when asked for funds.
Many years ago, our Ordnance Factory Board was hugely successful in making an indigenous reverse engineered AK-47 which was an instant hit with the armed forces but Mikhail Kalashnikov, the inventor of the gun made a hue and cry when he saw the unauthorized version on display at the defence expo in Delhi and threatened to take legal action. Thereafter, OFB agreed to pay him royalty. Now of course, the AK series is made by an Indo-Russian joint venture legally. |
