Reliance and Rolls-Royce announce a joint combat engine for India's stealth fighter

The two companies declared an intent to design, develop and manufacture a sovereign engine for the Advanced Medium Combat Aircraft. No investment figure was given.

India's largest private company and a British engine maker said on Friday that they intend to design and build a combat aircraft engine in India, addressing the one part of a fighter programme that the country has never managed to produce for itself.

Reliance Industries and Rolls-Royce issued a joint statement announcing their strategic intent to partner and to offer capabilities for the design, development, manufacturing and delivery of a sovereign indigenous combat engine for the Advanced Medium Combat Aircraft programme. The aircraft is India's fifth generation stealth multirole fighter, being developed at home for its air force.

The statement did not give the scale of investment either company will make, and it did not give a date for a first engine run or a first flight.

The gap the partnership is aimed at

India is among the largest importers of arms in the world and has spent a decade trying to reduce that position, particularly its dependence on Russia as its traditional main supplier. It has turned to the United States and France for aircraft, and has approved a series of large purchases: 39 billion dollars for a Rafale proposal, and 5.46 billion dollars last month for missiles, electronic warfare systems and loitering munitions.

Aircraft can be bought. Engines are the part that no country has yet acquired by purchase, because the metallurgy, the hot section design and the test data behind them are held closely by the handful of firms that have them. A fifth generation airframe without a domestic engine remains an import in the part that matters most.

What an intent is and is not

What was announced is an intent to partner, not a contract, a price or a delivery schedule. Rolls-Royce builds engines for the large commercial aircraft manufacturers as well as for military types, and its chief executive described the partnership as a step towards a self-reliant aerospace industry in India.

Reliance has been expanding from energy and telecommunications into military aerospace and munitions, under the domestic manufacturing policy the government has pursued for a decade. The announcement was made on the eve of the country's 80th independence day, and the defence minister used the same occasion to describe modernisation of the armed forces as driven by a self-reliant and future ready defence sector.

What to watch

The tests of this one are ordinary and will take years to answer: whether a definitive agreement follows the intent, what work share sits in India, which technologies transfer and on what licence terms, and whether an engine reaches a test bed. Announcements of this kind have preceded both real programmes and nothing at all.

Neither company has said when a definitive agreement is expected.
