India Rejects F-35 After Trump Tariffs, Pivots to Russian Partnership
New Delhi's formal withdrawal from $8-12B fighter program marks first major allied defense reversal under US trade policy, accelerating indigenous manufacturing push and strategic realignment.
India formally rejected the US F-35 fighter procurement in August 2025, eight months after President Trump personally pitched the sale during Prime Minister Modi’s White House visit, following Trump’s imposition of 25% tariffs on Indian imports. The decision eliminates $8-12 billion in projected contracts for Lockheed Martin’s flagship program and marks the first time a major US ally has reversed a defense acquisition commitment in direct response to trade policy escalation.
From Partnership to Pushback
Trump’s February 2025 offer positioned the F-35 sale as the cornerstone of expanded bilateral Defense ties, according to AeroTime. The proposal included potential assembly operations at Hindustan Aeronautics Limited facilities with integration of Indian-manufactured avionics and electronic warfare systems. Within five months, Trump announced 25% Tariffs on Indian goods effective August 1, 2025—a decision that blindsided New Delhi and undermined diplomatic momentum from Modi’s state visit.
India communicated its withdrawal to US officials in early August 2025, per The National Interest. “The government is more interested in a partnership focused on jointly designing and manufacturing defense equipment domestically,” an Indian official told Bloomberg. The phrasing signals institutional rejection of procurement-only arrangements—a shift formalised in India’s draft Defence Acquisition Procedure 2026, which prioritises indigenous design and intellectual property ownership over foreign platform purchases.

The rejection carries operational logic beyond trade friction. India’s existing S-400 air defense system—purchased from Russia despite US sanctions threats—creates integration constraints with F-35 networks, which require participating nations to accept US-controlled secure communications architecture. New Delhi also secured 26 Rafale M carrier-based fighters from France in April 2025, with deliveries scheduled for 2028-2030, filling immediate naval aviation requirements without F-35 dependency.
Russia Offers Alternative With Full Technology Access
Moscow moved swiftly to fill the gap. Russia offered India the Su-57E fifth-generation fighter with full source code access and license production rights in May 2025, according to Defence Security Asia. The package includes co-development of GaN-based AESA radar systems with Hindustan Aeronautics Limited and Defence Research and Development Organisation, directly addressing India’s technological sovereignty demands that US proposals cannot match under International Traffic in Arms Regulations frameworks.
| Factor | F-35A (US) | Su-57E (Russia) |
|---|---|---|
| Source code access | Restricted | Full transfer |
| S-400 compatibility | Incompatible | Integrated |
| Local production rights | Assembly only | License manufacturing |
| Co-development options | Limited | AESA radar, avionics |
The Russian offer arrives as India’s indigenous Advanced Medium Combat Aircraft program remains at least nine years from operational deployment. India’s defence production reached ₹1.27 lakh crore ($15.2 billion) in fiscal year 2023-24, with defence exports hitting ₹23,622 crore in FY 2024-25, according to Ministry of Defence data. The government targets ₹50,000 crore ($5.9 billion) in annual defence exports by 2029, requiring technology partnerships that transfer design capabilities rather than finished goods.
AUKUS Cohesion Under Pressure
The F-35 reversal compounds broader alliance reliability concerns across the Indo-Pacific. The US Department of Defense initiated formal review of the A$368 billion ($240 billion) AUKUS submarine deal in June 2025 for alignment with Trump’s ‘America First’ agenda, according to CHINA US Focus. Australia and the United Kingdom—both critical F-35 partners with integrated production roles—face tariff exposure on defense components under Trump’s evolving trade regime.
Trump reduced India’s tariff rate from 50% to 18% on February 2, 2026, after Indian oil companies agreed to limit Russian oil purchases, per trade policy documentation. The reduction has not revived F-35 discussions—New Delhi’s strategic calculus has shifted beyond transactional tariff negotiations toward structural defense independence.
The broader pattern extends beyond India. Army Technology documented supply chain disruptions across AUKUS as UK and Australian defense suppliers navigate tariff exposure on critical submarine components. The uncertainty undermines the integrated production model that underpins contemporary allied defense cooperation—a model premised on tariff-free movement of dual-use technologies and components.
Indigenous Manufacturing Accelerates
India’s draft Defence Acquisition Procedure 2026, released February 10, 2026, institutionalises the policy shift driving the F-35 rejection. The framework transitions from ‘Make in India’ to ‘Owned by India,’ requiring foreign partners to transfer design intellectual property and manufacturing rights rather than merely assembling imported kits. Outlook Business analysis indicates the policy will exclude platforms like the F-35, where source code and core avionics remain under US export control.
India’s defence budget grew from ₹2.53 lakh crore in FY 2013-14 to ₹6.81 lakh crore in FY 2025-26, with procurement increasingly directed toward indigenous platforms and technology-transfer partnerships. The shift reflects lessons from decades of dependence on foreign suppliers during conflicts—including US arms embargoes during the 1965 and 1971 wars with Pakistan, and Soviet withdrawal of technical support following the USSR’s collapse.
The Russian Su-57E offer aligns precisely with these requirements. Unlike US defense partnerships governed by International Traffic in Arms Regulations—which restrict technology transfer even to treaty allies—Russian deals typically include complete manufacturing data packages and source code access for customer nations willing to establish licensed production. This model enabled India’s successful Su-30MKI program, which now manufactures the aircraft domestically with progressively higher indigenous content percentages.
What to Watch
Track whether India formalises the Su-57E partnership in coming months—any production agreement will signal permanent strategic decoupling from US fighter platforms and validate Russia’s technology-transfer model as superior for nations prioritising sovereignty. Monitor AUKUS submarine deal progress following the June 2025 review; delays or scope reductions will confirm that trade policy has structurally damaged alliance defense cooperation beyond India. Watch for additional allied nations—particularly in Southeast Asia—citing the India precedent when declining US defense platforms in favour of Russian, European, or indigenous alternatives offering greater technological autonomy. Finally, observe whether Lockheed Martin or the Pentagon propose revised F-35 partnership models with expanded technology transfer to salvage export competitiveness—though ITAR reform faces congressional resistance that may prove insurmountable regardless of market pressure.
