The India–UK FTA and Defence: A New Corridor for Aerospace, Advanced Manufacturing and Technology Partnerships?

What the New Trade Framework Could Mean for Defence Companies and Why the FTA Does Not Remove India’s FDI, Licensing, Procurement or National Security Rules

The India–UK Comprehensive Economic and Trade Agreement (“CETA” or the “India–UK FTA”) has generated considerable interest across sectors ranging from automobiles and pharmaceuticals to technology and consumer goods. Yet one industry requires a distinctly different analysis, that is defence and aerospace.

India’s Defence Modernisation and UK Capabilities

India is in the midst of one of the world’s largest defence modernisation programmes. Alongside strengthening its military capabilities, the Government has prioritised domestic manufacturing, technology development and greater participation by private industry under initiatives such as Make in India and Aatmanirbhar Bharat.

The United Kingdom, meanwhile, possesses world-class capabilities in aerospace, defence engineering, advanced manufacturing, naval systems, cyber technologies and research and development.

Against this backdrop, the India–UK FTA has the potential to deepen commercial and technological collaboration. However, businesses should avoid assuming that the Agreement liberalises defence trade in the same manner as ordinary commercial sectors.

Defence remains a highly regulated industry where national security considerations, licensing requirements, foreign investment restrictions and procurement policies continue to play a decisive role.

The real opportunity lies not in unrestricted market access, but in creating a stronger framework for long-term industrial partnerships between Indian and UK defence ecosystems.

A Strategic Opportunity Beyond Conventional Trade

India’s Defence Requirements

India’s defence requirements span a wide range of capabilities, including:

• military aircraft and aerospace systems;
• naval platforms;
• defence electronics;
• unmanned aerial systems;
• cyber defence;
• artificial intelligence;
• advanced materials;
• electronic warfare;
• communications technologies; and
• space and satellite systems.

The United Kingdom complements these requirements through its established strengths in defence innovation, aerospace engineering, propulsion systems, maritime technologies, advanced manufacturing and high-value research.

Future Modes of Cooperation

Accordingly, the future of India–UK defence cooperation is likely to be driven less by traditional buyer-seller relationships and more by:

• joint ventures;
• technology collaborations;
• licensed manufacturing;
• research partnerships;
• co-development programmes;
• component manufacturing; and
• integration into global defence supply chains.

For businesses, the FTA should therefore be viewed as a catalyst for industrial cooperation rather than simply a tariff-reduction agreement.

What the FTA Changes and What It Does Not

Certain provisions of the Agreement may improve the commercial environment for businesses involved in civilian aerospace, advanced engineering and dual-use manufacturing by facilitating trade, investment and cross-border commercial relationships. However, the FTA does not override domestic laws governing defence production or national security.

Companies must continue to comply with:

• defence licensing requirements;
• export control regulations;
• foreign investment rules;
• industrial licensing obligations;
• end-use restrictions;
• technology transfer controls; and
• government procurement policies.

The regulatory framework applicable to civilian aerospace products may differ significantly from that governing military equipment or strategic technologies. Businesses should therefore assess each product, technology and transaction individually rather than assuming uniform treatment under the FTA.

Defence Procurement Remains Subject to National Security Considerations

One of the recurring misconceptions surrounding modern trade agreements is that government procurement chapters automatically provide unrestricted access to public contracts. That is not the case in the defence sector.

Governments generally preserve broad discretion to protect essential security interests and to regulate defence acquisitions through specialised procurement frameworks.

In India, defence procurement continues to be governed by sector-specific policies, including the Defence Acquisition Procedure (DAP), offset obligations where applicable, indigenous procurement preferences and security-related eligibility criteria.

UK suppliers seeking to participate in India’s defence market must therefore continue to satisfy applicable procurement requirements, technical qualifications and security clearances. Likewise, Indian companies pursuing opportunities in the UK defence sector must comply with the UK’s procurement and security regulations.

The FTA may facilitate commercial engagement, but it does not create an automatic right to participate in every defence procurement programme.

Foreign Investment Continues to Be Regulated

Cross-border investment is expected to increase as India and the UK deepen their strategic economic partnership. However, investments in defence remain subject to India’s foreign direct investment (FDI) policy, sectoral conditions and, where applicable, government approval requirements.

Prospective investors should carefully evaluate:

• applicable FDI thresholds;
• licensing requirements;
• ownership structures;
• governance rights;
• security clearances;
• technology transfer obligations; and
• compliance with sector-specific regulations.

Investment decisions should therefore be supported by comprehensive legal, regulatory and national security due diligence.

Technology Transfer Will Remain Central

For many defence companies, the greatest commercial opportunity may lie in technology collaboration rather than the export of finished equipment. Technology licensing, collaborative development, manufacturing partnerships and localisation initiatives are likely to become increasingly important as India seeks to strengthen indigenous defence capabilities.

These arrangements require careful attention to:

• intellectual property ownership;
• licensing rights;
• export control compliance;
• confidentiality obligations;
• restrictions on further transfers;
• know-how protection; and
• contractual allocation of risk.

Technology collaboration agreements should be structured with equal emphasis on commercial objectives and regulatory compliance.

Advanced Manufacturing and Supply Chains Could Benefit

Beyond traditional defence platforms, the Agreement may encourage greater collaboration in advanced manufacturing and precision engineering. Indian companies are increasingly becoming part of global aerospace and defence supply chains by manufacturing components, sub-assemblies and specialised engineering products.

UK companies seeking resilient and cost-effective supply chains may find India an increasingly attractive manufacturing base for qualifying products, subject to applicable export control and security requirements.

Areas of Increased Collaboration

• aerospace components;
• precision engineering;
• composite materials;
• avionics;
• maintenance, repair and overhaul (MRO);
• electronics manufacturing; and
• specialised industrial equipment.

For many businesses, supply-chain integration may represent a more immediate commercial opportunity than large defence platform contracts.

Cybersecurity and Emerging Technologies

Modern defence increasingly relies upon software, artificial intelligence, autonomous systems, satellite technologies, secure communications and cyber resilience. Many future India–UK collaborations are therefore likely to involve digital technologies alongside conventional defence manufacturing.

Businesses operating in these sectors should establish robust governance frameworks addressing:

• cybersecurity compliance;
• protection of classified information;
• secure software development;
• AI governance;
• data protection;
• supply-chain security; and
• contractual risk allocation.

Strong compliance systems are likely to become an important competitive advantage in cross-border defence collaborations.

Commercial Contracts Will Require Greater Sophistication

Cross-border defence transactions typically involve long-term contractual relationships and complex regulatory obligations. Companies should carefully review agreements relating to:

• technology licensing;
• manufacturing;
• joint ventures;
• engineering services;
• research collaboration;
• confidentiality;
• export compliance;
• indemnities;
• limitation of liability; and
• dispute resolution.

Well-drafted contractual frameworks are essential to managing legal, commercial and regulatory risks in strategic defence projects.

Practical Considerations for Businesses

Defence and aerospace companies seeking to leverage opportunities arising from the India–UK FTA should consider undertaking a comprehensive legal and commercial review covering:

• product classification;
• export control requirements;
• industrial licensing;
• FDI compliance;
• procurement eligibility;
• technology transfer structures;
• intellectual property protection;
• supply-chain optimisation;
• sanctions compliance; and
• contractual risk allocation.

An integrated review involving legal, regulatory, technical and commercial teams will often identify opportunities while mitigating compliance risks.

Conclusion

The India–UK FTA should not be viewed as an agreement that liberalises defence trade in the same manner as consumer goods or industrial products. National security, strategic technology and defence procurement will continue to be governed by specialised domestic legal frameworks in both jurisdictions.

Nevertheless, the Agreement strengthens the broader economic relationship between India and the United Kingdom and creates a favourable environment for deeper collaboration in aerospace, advanced manufacturing, defence technology and industrial partnerships.

For defence businesses, the greatest opportunities are likely to arise through co-development, technology transfer, joint ventures, supply-chain integration and long-term strategic investment rather than conventional import-export models.

Companies that combine commercial ambition with careful regulatory planning and robust compliance will be best placed to participate in the next phase of India–UK defence cooperation.
