Tejas and C-390 Millennium: India and Brazil’s Defense Trade Vision

India and Brazil are exploring a mutually beneficial deal to enhance their defense product exports. There are indications that this potential agreement could include the exchange of fighter jets, essentially functioning as a barter system. For example, India has a long-standing offset policy requiring foreign defense companies to reinvest a portion of their contract value back into India through technology transfer or other reciprocal benefits.

Many countries engage in such exchanges to support each other’s defense industries, thereby strengthening national policies and economies. A notable example is the barter deal between South Korea and Indonesia, where South Korea sold its T-50 jets to Indonesia in return for defense-related goods and trade advantages.

India-Brazil defence mutual benefits

If the India-Brazil deal comes to fruition, it could provide mutual benefits, as both nations are in need of advanced platforms. Brazil is well-known for its Embraer aircraft, which ranks as one of the top three manufacturers of private and commercial jets. However, Brazil lacks expertise in fighter jet production, and this deal could provide the exposure needed to enter the fighter jet market.

In 2014, Brazil made a significant purchase of 36 Gripen fighters, with deliveries expected by 2027. Brazil is also producing Gripen fighter jets at its Embraer plant, with SAAB and Embraer collaborating to enhance the performance of the Gripen aircraft further.

India Faces Shortage of Military Aircraft Materials

Currently, India faces a shortage of medium military transport aircraft and is seeking to acquire more. The C-130J and C-17 Globemaster, along with the Russian IL-76, are currently in service. However, the production of the C-17 has been halted, making it unavailable in the market, while the IL-76 is experiencing maintenance challenges due to a shortage of spare parts.
