Can India Afford to Say No to America’s F-35 Lightning?

In an era where air dominance shapes geopolitical outcomes, India finds itself at a pivotal defense juncture. With two nuclear-armed neighbors — China and Pakistan — rapidly upgrading their air fleets, India is under immense strategic pressure to match their advancements, particularly in stealth aviation.

As the global race to fifth-generation fighters heats up, India now has two highly potent but drastically different offers on the table: the American F-35 Lightning II, and the Russian Su-57E, complete with technology transfer and source code access — a rarity in international defense deals.

Russia’s Su-57E Offer: More Than Just a Fighter Jet

In a landmark defense proposal, Russia has offered India its Su-57E fifth-generation stealth fighter, developed by the renowned Sukhoi Design Bureau. But it’s not just the hardware that makes this offer tempting.

Russia is promising full technology transfer, access to source code, and provisions for local manufacturing through Hindustan Aeronautics Limited (HAL). This means India could not only fly the Su-57E but also build, modify, and potentially co-develop future versions — a huge step toward strategic autonomy.

The Su-57E is a twin-engine multirole stealth fighter designed for both air superiority and strike missions. It boasts a top speed of Mach 2 (2,450 km/h) and a combat range of approximately 1,900 km. Enhanced agility, radar-evading stealth features, and its ability to target air, land, and maritime threats make it a lethal and versatile platform.

The F-35 Lightning II: Proven But Restricted

On the other side is the U.S.-made F-35 Lightning II, developed by Lockheed Martin and already in operation with several NATO countries. India has shown interest in acquiring the F-35A variant, designed primarily for the Air Force.

The F-35 is a single-engine, single-seat stealth aircraft that flies at Mach 1.6 (1,975 km/h) with a combat range of around 1,500 km. It is known for its advanced sensor fusion, stealth profile, and multi-domain warfare capability, where it can seamlessly integrate with ships, drones, and ground stations in real time.

However, the catch lies in the lack of technology transfer. The U.S. is unlikely to grant India access to the F-35’s source code or allow modifications. Maintenance and software updates will remain under U.S. control, limiting India’s operational independence.

The China-Pakistan Equation: Strategic Urgency

China has already deployed its Chengdu J-20 fifth-generation fighter near the Indian border, and reports suggest it’s preparing to export similar stealth tech to Pakistan. This dual-front development poses a serious threat to India’s air superiority.

After suffering a major setback during India’s Operation Sindoor, Pakistan has also announced a significant increase in its defense budget — nearly 20% despite economic turmoil. These indicators point toward a regional arms race, especially in aerial stealth capability.

In this context, India’s need for a next-gen stealth platform is not just about catching up — it’s about staying strategically relevant and maintaining a credible deterrent in the subcontinent.

India’s Indigenous Efforts: AMCA in the Making

India’s defense research bodies — DRDO and HAL — are currently working on the Advanced Medium Combat Aircraft (AMCA), India’s first indigenous fifth-generation stealth fighter. While the project is ambitious and technologically promising, it remains several years away from deployment.

Until the AMCA is ready for production and induction, India needs an interim fifth-gen solution. Choosing between the Su-57E and F-35A could serve as either a technological bridge or a long-term strategic alignment — depending on which path India chooses.

Beyond Aircraft: The Battle for Sovereignty and Self-Reliance

The choice is not just about buying a jet — it’s about choosing between operational sovereignty vs. alliance-based dependence.

The Su-57E represents empowerment, offering India a chance to co-own cutting-edge aviation technologies and potentially influence future designs. It aligns well with India’s Atmanirbhar Bharat (self-reliant India) vision in defense manufacturing.

In contrast, the F-35 represents global prestige and proven capability, but with tight restrictions. Its deployment would strengthen U.S.-India military ties but also place India in a client-state position when it comes to software, upgrades, and support.

Local Manufacturing and Economic Boost

Russia’s offer includes setting up production lines in India, which would generate local employment, enhance industrial expertise, and accelerate India’s aviation R&D. This kind of localization is absent in the F-35 deal, which is built around U.S.-controlled global supply chains.

Moreover, local Su-57E manufacturing could complement the AMCA project, allowing Indian engineers and scientists to absorb, adapt, and enhance their domestic 5th-gen fighter program with real-world experience.

Final Decision: Tactical Edge or Strategic Future?

Choosing between these jets is more than a tactical purchase — it’s a long-term doctrinal shift. While the F-35 offers plug-and-play superiority, the Su-57E offers a foundation to build upon.

The U.S. may offer defense deals with strong diplomatic upside, but Russia’s proposal empowers India technologically and economically. If India wants to build an aerospace ecosystem of its own, the Su-57E might be the key.
