The India defence budget is one of the largest military outlays in the world, regularly placing the country among the top three or four spenders globally. It pays for a standing force of well over a million active personnel, a vast veteran community, three armed services, and a long modernisation shopping list that stretches from fighter jets and submarines to drones, missiles and artillery. Every year, when the Union Budget is presented, the Ministry of Defence receives one of the biggest single allocations of any ministry.
Yet a large rupee number does not tell the whole story. Measured as a share of the national economy, India’s defence spending is modest, at around 2% of GDP, and a big part of it is consumed by salaries and pensions rather than new equipment. This explainer breaks down how the money is raised and split, how the armed forces actually buy their weapons, why indigenisation has become the central theme of Indian defence policy, and what the main debates are. Figures here are kept approximate and qualitative, so that the picture stays accurate across budget cycles.

How Big Is India’s Defence Budget?
In absolute terms, only a handful of countries spend more on their militaries than India does. The reasons are straightforward. India maintains one of the largest armies in the world, a blue-water navy that is steadily expanding, and one of the biggest air forces. It also shares long and sensitive land borders, some of them still disputed, with neighbours with whom it has fought wars, and it has an extensive coastline and island territories to secure.
Large in rupees, modest in proportion
The picture changes when spending is expressed relative to the economy. India’s defence spending has hovered at around 2% of GDP in recent years, while several countries facing active security threats spend a noticeably higher share. India’s economy is big, so even a modest percentage translates into a very large sum. Analysts therefore often say that India’s defence burden is moderate, but that its needs are unusually heavy.
Why the number matters
Defence spending is not just a ledger item. It shapes industrial policy, technology development, foreign relations and even regional employment. A decision to buy a fighter aircraft from abroad or build one at home influences supply chains, jobs and strategic partnerships for decades.
How the Money Is Raised and Allocated
Defence spending is financed from the government’s overall resources, mainly taxes and borrowing, and there is no separate “defence tax” earmarked for the purpose. Every year, as part of the Union Budget, the Ministry of Defence presents its Demands for Grants, which Parliament examines and votes on. The allocation is then spread across several heads.
- Defence Services (Army, Navy, Air Force): the largest component, covering the three services, joint staff organisations and related establishments.
- Defence Pensions: payments to retired armed forces personnel and their families, shown as a separate head.
- Defence Ministry (Civil): the secretariat, along with related civil establishments and research, including the Defence Research and Development Organisation (DRDO).
The actual spending does not always match the budget estimates. Allocations are revised during the year, and unspent capital funds can lapse at year end, a feature that has repeatedly drawn attention from parliamentary committees. Planning is also guided by long-term documents, including a long-term perspective plan and five-year plans for acquiring capital equipment, even though funds themselves are approved annually.
Revenue vs Capital: The Core Split
To understand Indian defence spending, one has to understand the basic distinction between revenue and capital expenditure. This single split explains most of the debates around defence finance.
| Feature | Revenue expenditure | Capital expenditure |
|---|---|---|
| What it covers | Salaries, allowances, rations, fuel, maintenance, stores and running costs; defence pensions are accounted for separately but are of the same recurring nature | Acquisition of aircraft, ships, submarines, tanks, missiles, weapons systems, land and military infrastructure |
| Nature | Recurring, largely fixed and hard to cut | Lumpy, project based and flexible from year to year |
| Effect on strength | Keeps the existing force running | Builds future capability and replaces ageing equipment |
| Typical pressure | Grows steadily with pay revisions and the size of the veteran population | Often squeezed when revenue needs rise |
Revenue expenditure is the cost of keeping a very large force fed, paid, housed, equipped and operational every day. Capital expenditure is the money for modernisation, and it is what turns into new aircraft on the runway or new ships in the harbour. The tension between the two is the central problem of Indian defence budgeting.
The Pension Burden and Why It Matters
India has a very large population of military pensioners, since service personnel typically retire at a young age compared with civil employees, and then draw a pension for many decades. Over time, as pay commissions revise salaries and the policy of “One Rank One Pension” was implemented, the pension bill has swelled into one of the biggest single items in the defence budget.
The squeeze on modernisation
When salaries and pensions together take up a large part of the defence outlay, the amount left for capital expenditure shrinks. A force can then end up with a large manpower base but ageing equipment, a situation sometimes described as being “top heavy” on costs and “bottom heavy” on modernisation. Armed forces have long warned that an ageing inventory, such as legacy aircraft and ships nearing the end of their service lives, needs urgent replacement, which in turn requires capital funds.
Agnipath and the manpower question
One reason behind the Agnipath scheme, introduced in 2022, was to bring down the long-term salary and pension liability and to keep the armed forces younger. Under it, most new recruits serve for a fixed short term, with only a limited share retained for longer service. The scheme has been widely discussed, with supporters pointing to a younger profile and lower recurring costs, and critics raising concerns about training, experience and career prospects after release. Whatever one’s view, the link between manpower policy and budget structure is clear.
How the Three Services Share the Pie
The Army, Navy and Air Force do not receive equal amounts, and they should not, given their very different roles. The Army is by far the most manpower-intensive service, with the largest number of personnel, so a big proportion of its share goes to pay, allowances and running costs, leaving a smaller fraction for capital acquisitions.
- Army: receives the biggest slice of the Services’ allocation, much of it as revenue expenditure because of its numbers, but also needs artillery, armoured vehicles, air defence, drones and infantry equipment.
- Navy: a smaller overall share but a relatively higher proportion spent on capital, because ships, submarines and naval aviation are expensive and have long build times.
- Air Force: a mid-sized share with a heavy capital element, driven by fighter aircraft, transport planes, helicopters and radar and missile systems.
This difference in spending patterns is why the capital share varies by service. Calls for a sharper focus on maritime strength in the Indian Ocean Region, and for air power to counter threats on two fronts, regularly feature in discussions on how the pie should be divided. Efforts to improve joint planning, discussed later, are partly meant to decide such trade-offs more rationally.
How India Buys Weapons: The Procurement System
Buying military equipment in India is a layered process, designed to be transparent and accountable but often criticised for being slow. The rulebook is the Defence Acquisition Procedure, and the version known as DAP 2020 replaced the earlier Defence Procurement Procedure, with a strong emphasis on self-reliance.
The journey of a proposal
- A service identifies a requirement and records it in its long-term plans.
- The Defence Acquisition Council grants “Acceptance of Necessity” (AoN), the first formal approval for a major purchase.
- Staff requirements are prepared, a request for proposals is issued and vendors respond.
- Technical evaluation and field trials follow, after which commercial bids are opened and negotiated.
- The final deal is approved by the competent financial authority, which for large deals means the Cabinet Committee on Security, and a contract is signed.
The Defence Acquisition Council
The Defence Acquisition Council (DAC) is the highest decision-making body in the Ministry of Defence for capital acquisition. It is chaired by the Defence Minister, and it sets the direction for purchases, approves the category of acquisition and clears major proposals. Because it grants the very first approval, the DAC effectively decides whether a platform will be built in India or imported.
DAP 2020 and Its Acquisition Categories
The Defence Acquisition Procedure sorts purchases into categories, arranged in a clear order of preference. Indian-designed and Indian-built equipment sits at the top, and purchasing from abroad sits at the bottom.
| Category | Meaning |
|---|---|
| Buy (Indian-IDDM) | Equipment that is Indigenously Designed, Developed and Manufactured, with a minimum level of indigenous content; the top priority category |
| Buy (Indian) | Equipment manufactured in India by Indian vendors, with a prescribed minimum indigenous content |
| Buy and Make (Indian) | Purchase from an Indian vendor with a partner, involving transfer of technology and part-build in India |
| Buy (Global, Manufacture in India) | A foreign firm sets up local production, usually with an Indian partner, with a stated share of local content |
| Buy (Global) | Direct import from a foreign supplier, used only when no domestic option exists; the last resort |
The aim of this design is to make domestic sourcing the default and to justify imports as an exception. The finer details of indigenous content percentages and eligibility have been revised in later updates, so readers should check the latest version of the procedure for specifics.
Why Procurement Takes So Long
One of the oldest complaints about Indian defence acquisition is the time it takes. Big contracts have historically taken many years, sometimes over a decade, from the first proposal to delivery. Several factors contribute.
- Multiple approval layers: a proposal passes through service headquarters, the ministry, finance authorities and ultimately the highest political committee.
- Extensive trials: equipment is tested in diverse terrains and climates, from deserts to high-altitude glaciers.
- Vendor disputes and anti-corruption caution: after past controversies, officials have been wary of decisions that could later be questioned, which slows down choices.
- Changing requirements: specifications sometimes shift during the process, which forces a restart.
- Budget cycles: funds approved yearly can lapse, which complicates multi-year payments.
Successive procedural reforms have tried to shorten timelines, introducing faster tracks for urgent “emergency” needs and clearer deadlines for each stage. Delays remain a point of discussion, but the direction of reform is plainly toward more speed and more predictability.
The Big Shift to Indigenisation
For decades, India was among the world’s largest importers of arms, relying on a handful of foreign suppliers for aircraft, ships, tanks and missiles. This dependence created concerns over cost, spare parts and strategic autonomy. In recent years, policy has swung firmly toward self-reliance under the broader Aatmanirbhar Bharat theme.
Positive indigenisation lists
The government has notified several “positive indigenisation lists”, which name categories of defence items that can no longer be imported after a specified date, so that domestic industry can step in. They cover a very wide range of items, from sub-systems and components to major platforms, with import bans phased in over a number of years. By announcing the timelines in advance, the government gives manufacturers the certainty needed to invest.
A reserved share of the capital budget
A significant and rising portion of the capital acquisition budget is now earmarked for procurement from domestic industry, with part of it kept aside for the private sector. This ring-fencing is meant to guarantee that Indian firms have a predictable order pipeline, rather than competing against imports in every tender.
Private Sector, Start-ups, Industrial Corridors and Ordnance Reform
Historically, defence production was almost entirely the work of government-owned units. Policy has since opened the field, and the private sector, including large conglomerates and a growing number of small and medium enterprises, now takes part in defence manufacturing.
- iDEX (Innovations for Defence Excellence): launched in 2018, it connects start-ups, small firms and innovators with the armed forces’ needs, offering funding and a route to first orders.
- Defence Industrial Corridors: dedicated manufacturing zones, set up in Uttar Pradesh and Tamil Nadu, designed to attract investment, build supplier clusters and create testing infrastructure.
- Foreign direct investment: the limits for FDI in defence manufacturing have been raised in stages, encouraging joint ventures and technology partnerships.
- Technology transfer and co-production: major foreign deals increasingly include a requirement for local production and transfer of know-how.
The broader idea is to build a full domestic supply chain, from raw materials and components through to finished weapons, which would bring down import bills and give the country the ability to produce in times of crisis.
From Ordnance Factory Board to DPSUs
India’s ordnance factories, among the oldest industrial establishments in the country, were for a long time run as a departmental organisation under the Ordnance Factory Board. They produced a wide range of items, from rifles and ammunition to vehicles, but were often criticised for limited autonomy, inefficiency and a lack of competition.
In October 2021, the Ordnance Factory Board was dissolved and its factories were reorganised into seven new Defence Public Sector Undertakings (DPSUs). The goal was to give them corporate autonomy, a clear business focus and the ability to compete, innovate and export. These new companies join established defence public sector enterprises in aviation, shipbuilding, electronics and missiles, which remain central to the domestic industry. Alongside them, the DRDO continues to lead research and development of indigenous systems.
The Debates and Strategic Stakes
Defence finance is rarely free of debate, and several questions recur in policy discussions.
Modernisation versus the revenue burden
Should the share of capital spending be protected even if manpower costs rise? Some analysts suggest a dedicated modernisation fund, or a leaner force with greater technology, while others point to the continuing need for large numbers in view of the border situation.
Import dependence versus the export push
India still needs certain advanced systems from abroad, particularly where domestic technology is not yet mature, such as some engines and high-end sensors. At the same time, India has set an ambition to grow its defence exports, and has begun to sell equipment to friendly countries. Balancing the need to import now with the goal to export later is a delicate task.
Jointness and theatre commands
The creation of the Chief of Defence Staff and the Department of Military Affairs in 2019 aimed to bring the three services closer together. Proponents of integrated “theatre commands” argue that shared planning, logistics and procurement would avoid duplication, and let funds be spent where they make the most operational difference. Details of such reforms continue to evolve.
Strategic importance
The defence budget is ultimately an instrument of national strategy. India lives in a complex neighbourhood, with unresolved border questions, maritime interests across the Indian Ocean and an expanding set of partnerships. A credible deterrent, which includes conventional forces and nuclear capability, depends on steady investment, trained personnel and dependable supply chains.
Self-reliance has a strategic purpose beyond saving foreign exchange. A country that depends on others for spares and ammunition can find itself vulnerable at an awkward moment, whereas a strong domestic industry offers resilience. It also provides economic returns through jobs, skills and technology that flow into civilian sectors such as aviation, electronics and space.
Conclusion
The India defence budget is best seen as a balancing act between several goals: maintaining a large force that can respond to threats on more than one front, honouring the commitments to veterans, and finding enough money for modernisation. The shift towards indigenisation, the opening of the sector to private firms and start-ups, the corporatisation of the ordnance factories and reforms such as Agnipath and greater jointness all try to respond to the same challenge, namely getting more capability for each rupee spent. How well these reforms work over the coming years will shape the country’s military preparedness (content last reviewed 1 October 2026).
Frequently Asked Questions
How big is the India defence budget compared with other countries?
In absolute terms, India is usually counted among the top three or four military spenders in the world. As a share of GDP, however, it is modest, at around 2%, which is lower than the share spent by several countries facing active conflicts.
What is the difference between revenue and capital expenditure in defence?
Revenue expenditure covers recurring costs such as salaries, allowances, stores, maintenance and, in the broader accounts, pensions. Capital expenditure is spent on acquiring new assets such as aircraft, ships, tanks, missiles and infrastructure, and is the money that funds modernisation.
Why are defence pensions such a big issue?
Armed forces personnel retire relatively young and draw pensions for many years, and pension rates have been raised through pay revisions and One Rank One Pension. As a result, the pension bill takes up a large part of the defence outlay and leaves less room for capital spending. This is one of the reasons behind reforms such as the Agnipath scheme.
What is the Defence Acquisition Council?
The Defence Acquisition Council (DAC) is the top body of the Ministry of Defence for capital acquisitions, headed by the Defence Minister. It grants the first formal approval, called Acceptance of Necessity, and decides in which category a purchase will fall.
What are the main categories under DAP 2020?
The Defence Acquisition Procedure 2020 ranks purchases by preference, starting with Buy (Indian-IDDM) for indigenously designed, developed and manufactured equipment, followed by Buy (Indian), Buy and Make (Indian), Buy (Global, Manufacture in India) and finally Buy (Global) for direct imports. The order favours domestic industry.
What are positive indigenisation lists?
These are lists notified by the government naming defence items that will no longer be imported after specified dates, so that Indian industry can supply them. They cover a wide range of components, sub-systems and platforms, and give manufacturers advance notice to invest.
