India Nears $1 Billion Deal for US-Made GE Jet Engines for LCA Fighters

27 August, 2025

Amid escalating trade tensions, India is close to finalizing a deal worth approximately $1 billion with American firm GE to procure 113 GE-404 engines. These engines will power the next batch of 97 indigenous LCA Mark 1A Tejas fighter jets. This purchase is in addition to a previous order for 99 engines. The deal's progression, despite the new US tariffs on Indian goods, highlights the continued strategic and defense partnership between the two nations, which operates in parallel to economic disputes.

Unpacked:

Why is India choosing American GE-404 engines for its Tejas fighter jets instead of developing indigenous engines?

India selects GE-404 engines due to their proven reliability, performance, and compatibility with Tejas jets. Indigenous engine programs have faced technical delays, making imported engines crucial for timely production and operational readiness of the LCA fleet.

How do the GE-404 engines compare to other fighter jet engines, such as Russia's RD-33MK, in terms of performance?

The Indian F404 version has a marginally superior thrust-to-weight ratio (about 7.87) compared to the RD-33MK (about 7.76). However, the RD-33MK offers slightly higher maximum afterburning thrust. Both engines are high-performance, but the F404 excels in agility and dry thrust.

What impact might continued US-India defense deals have on broader trade tensions and diplomatic relations between the two countries?

Despite economic disputes like tariffs, defense deals signal enduring strategic trust and cooperation. Such agreements help mitigate diplomatic strains by emphasizing mutual security interests, potentially facilitating dialogue on broader trade issues and maintaining stable bilateral relations.

What is the significance of the Tejas Mark 1A program for India's military modernization efforts?

The Tejas Mark 1A represents India's push for indigenous defense capability, replacing older aircraft and modernizing its air force. With plans for over 400 Tejas jets, this program enhances self-reliance, upgrades operational capabilities, and reduces dependence on foreign suppliers.
