India’s defence posture has undergone a decisive transformation in the last decade, marked by a shift from a predominantly reactive stance to a proactive, technology-driven, and integrated security framework. This evolution is anchored in policy reforms, increased budgetary allocations, and institutional strengthening since the early 2010s, culminating in the Union Budget 2023-24 allocation of ₹5.94 lakh crore (approximately USD 80 billion), a 12% increase over the previous year. Key actors include the Ministry of Defence (MoD), Defence Research and Development Organisation (DRDO), Defence Acquisition Council (DAC), and Strategic Forces Command (SCO), which collectively drive the shift towards strategic autonomy and enhanced deterrence capabilities. The significance lies in India’s response to evolving regional threats, particularly from China and Pakistan, and the global security environment that demands agile and integrated defence mechanisms.

Constitutional and Legal Framework Governing Defence

India’s defence is constitutionally a Union subject under Article 246, placing defence and related policies under the exclusive legislative competence of Parliament. Article 51A imposes a fundamental duty on citizens to defend the country, which underpins the ethical basis of national security. The legal framework includes the Defence of India Act, 1962 enacted during the Sino-Indian War for emergency powers, and the Armed Forces Special Powers Act (AFSPA), 1958, which grants special authority to armed forces in disturbed areas. The Defence Procurement Procedure (DPP) 2020 introduced reforms aimed at transparency and indigenisation, reinforced by Supreme Court rulings like Union of India v. Raghunath Thakur (2015), which mandated greater openness in procurement to curb corruption. The National Security Act, 1980 complements these by enabling preventive detention in security threats.

• Article 246: Union List includes Defence, enabling centralised policy and procurement.
• AFSPA, 1958: Legal basis for armed forces’ special powers in conflict zones.
• DPP 2020: Streamlined procurement, emphasising Make in India and faster acquisition.
• Union of India v. Raghunath Thakur: Supreme Court ruling enhancing procurement transparency.

Economic Dimensions: Budget, Indigenous Production, and Defence Exports

The defence budget for 2023-24 at ₹5.94 lakh crore represents 2.15% of GDP, reflecting a strategic prioritisation of defence amidst competing fiscal demands. Defence exports surged by 53% to ₹13,000 crore in FY 2022-23, signalling growing global competitiveness. The Make in India initiative targets increasing indigenous defence production from 60% currently to 75% by 2027, supported by raising the FDI limit to 74% under the automatic route since 2020. These measures aim to reduce dependence on imports, enhance self-reliance, and foster a domestic defence industrial base capable of innovation and export.

• 2023-24 defence budget: ₹5.94 lakh crore, 12% increase over previous year (Union Budget 2023-24).
• Defence exports grew 53% to ₹13,000 crore in FY 2022-23 (MoD Annual Report 2023).
• Indigenous production at 60%, target 75% by 2027 (Make in India Defence Policy 2020).
• FDI limit in defence manufacturing increased to 74% automatic route (DPIIT, 2020).

Institutional Architecture Driving India’s Defence Modernisation

The Defence Research and Development Organisation (DRDO) spearheads indigenous R&D, focusing on missile technology, electronic warfare, and next-generation platforms. The Indian Air Force (IAF) and Indian Navy (IN) are expanding capabilities in air defence, strategic deterrence, and maritime security, including blue-water naval ambitions. The Ministry of Defence (MoD) formulates policy and oversees procurement, while the Defence Acquisition Council (DAC) is the apex body for procurement decisions, aiming to expedite acquisitions. The Strategic Forces Command (SCO), operational since 2003, manages India’s nuclear arsenal, maintaining credible minimum deterrence. Coordination gaps between these institutions remain a challenge but reforms aim to enhance jointness and integration.

• DRDO: Indigenous R&D, missile and defence tech development.
• IAF: Air defence, strategic deterrence, modernization with 5th generation fighters.
• IN: Maritime security, blue-water navy expansion.
• MoD: Policy formulation, procurement oversight.
• DAC: Apex procurement decision-making body.
• SCO: Nuclear arsenal management, credible deterrence.

Comparative Analysis: India vs China Defence Posture

Critical Gaps in India’s Defence Posture

Despite increased budget and policy reforms, India’s defence procurement remains encumbered by bureaucratic inertia and inter-service coordination challenges. This leads to slower induction of critical technologies compared to China and the US, creating capability gaps in areas such as missile defence, cyber warfare, and advanced naval platforms. The fragmented procurement system and delays in project execution undermine the objective of strategic autonomy. Additionally, the pace of indigenous production, though improving, still lags behind the scale and sophistication achieved by China.

• Bureaucratic delays in procurement impede timely capability upgrades.
• Lack of seamless integration between Army, Navy, and Air Force affects joint operations.
• Indigenous R&D and production capacity insufficient to match regional competitors.
• Capability gaps in emerging domains like cyber and space security persist.

Significance and Way Forward

• Accelerate procurement reforms by empowering DAC and integrating services under a unified command structure.
• Enhance DRDO’s collaboration with private sector and academia to fast-track innovation.
• Expand defence exports by leveraging Make in India and bilateral defence diplomacy.
• Invest in emerging domains such as cyber, space, and artificial intelligence for comprehensive security.
• Strengthen institutional coordination among MoD, armed forces, and intelligence agencies for agile decision-making.
