India’s defence sector is witnessing an unprecedented surge, propelled by a potent mix of strategic imperatives and economic opportunities. Geopolitical tensions along its borders, substantial government budgets, and a robust push for self-reliance through initiatives like Make in India and Atmanirbhar Bharat are transforming India from a traditional defence importer into a formidable global player in manufacturing and exports. This transformation not only bolsters national security but also presents a dynamic opportunity for investors seeking to capitalise on a sector poised for sustained growth. In this detailed exploration, we delve into the drivers of this boom, spotlight India’s homegrown innovations, analyse government spending, highlight investment prospects, assess potential risks, and draw lessons from mature markets to chart the path forward.

Why the sector is thriving

India’s defence sector is experiencing rapid growth due to a confluence of strategic, economic, and policy-driven factors:

• Geopolitical imperatives: Persistent border tensions, particularly with neighbouring countries like China and Pakistan, have underscored the urgent need for advanced defence capabilities. Recent diplomatic efforts to stabilise the Line of Actual Control (LAC) with China reflect India’s proactive stance in securing its borders, necessitating robust military preparedness.

  
  

• Record-breaking budgets: The government has significantly ramped up defence spending, with the FY 2025-26 budget reaching ₹6.81 lakh crore (approximately US$81 billion), a 9.5% increase from the previous fiscal year. This substantial allocation is earmarked for modernising equipment, enhancing infrastructure, and supporting indigenous production.
  
  

• Self-reliance policies: Initiatives like Make in India and Atmanirbhar Bharat are pivotal in reducing India’s reliance on foreign arms, which accounted for 9.8% of global arms imports in 2023. These policies encourage domestic manufacturing, spur innovation, and create thousands of jobs, strengthening both the economy and national security.

This strategic shift has repositioned India as a producer of sophisticated defence systems, moving away from its historical dependence on imports and fostering a vibrant ecosystem of domestic innovation and manufacturing.

Homegrown defence technology:

India’s defence technology is earning accolades on the global stage, enhancing national security while opening lucrative export markets:

• Akash missile system: This surface-to-air missile, equipped with advanced guidance technology, is a testament to India’s engineering prowess. Capable of intercepting aerial threats at ranges up to 30–35 km, the Akash system is a cornerstone of India’s air defence and has attracted interest from international buyers.
  
  

• Export surge: In FY 2024-25, India’s defence exports reached ₹23,622 crore, marking a 12% increase from the previous year, with an ambitious target of ₹50,000 crore by 2029–30. Countries in Southeast Asia, Africa, and the Middle East are increasingly turning to Indian solutions, which offer cost-effective alternatives to Western and Russian systems.

  
  

• DRDO’s innovations: The defence Research and Development Organisation (DRDO) is at the forefront of technological advancements, developing cutting-edge systems like directed-energy weapons, anti-drone technologies, and hypersonic missiles. The indigenous Air Independent Propulsion (AIP) system, set for integration into Kalvari-class submarines in 2025, will significantly enhance underwater endurance, bolstering naval capabilities.
  
  

• Private sector dynamism: Private companies are playing an increasingly vital role. For instance, TechEagle and JSW Defence are investing heavily in drone manufacturing, while Paras Defence is planning a ₹12,000 crore Optics Park in Maharashtra to produce advanced optical systems for defence applications.

These advancements are supported by centres of excellence that foster collaboration between government, industry, and academia, positioning India as a global innovator in defence technology.

Government spending

The Indian government’s unwavering commitment to defence is evident in its substantial budget allocations and supportive policy framework:

• FY 2025-26 budget: The defence budget for FY 2025-26 stands at ₹6.81 lakh crore, with 46% allocated to revenue expenditure (salaries, operational preparedness), 26% to capital outlay (new equipment modernisation), and 24% to pensions. Notably, 75% of the modernisation budget is reserved for domestic procurement, reinforcing self-reliance goals.

  
  

• Border infrastructure: The Border Roads Organisation received ₹7,146.50 crore, a 9.74% increase from the previous year, to strengthen infrastructure in strategic regions like Arunachal Pradesh, Ladakh, and Jammu & Kashmir. Projects include all-weather roads and tunnels to enhance troop mobility and logistics.

  
  

• Budget growth trajectory: Since 2020, the defence budget has grown by approximately 32%, from ₹4.71 lakh crore to ₹6.81 lakh crore. This sustained increase underscores a long-term commitment to modernising the armed forces, with a focus on indigenous production and technological advancement.

These investments are not only enhancing military capabilities but also driving economic growth by creating jobs, fostering industrial development, and supporting small and medium enterprises in the defence supply chain.

Defence stocks

India’s defence companies are capturing significant investor attention, driven by strong order books, government backing, and a favourable market environment.

• Hindustan Aeronautics Limited (HAL): As a leading manufacturer of aircraft, helicopters, and engines, HAL is benefiting from orders for the Tejas Light Combat Aircraft, Advanced Light Helicopters, and Sukhoi Su-30 upgrades. Its export potential to countries like Argentina and Egypt further enhances its growth prospects.
  
  

• Bharat Electronics Limited (BEL): specialising in radar, communication systems, and electronic warfare equipment, BEL is seeing increased demand as modern warfare increasingly relies on advanced electronics. Its role in projects like the Integrated Air Command and Control System positions it for sustained growth.
  
  

• Bharat Dynamics Limited (BDL): With a growing order book for missile systems like the Akash, BrahMos, and Astra, BDL is well-positioned for revenue growth. Its partnerships with international firms for co-production further strengthen its market position.

  
  

Risks to consider

While the defence sector offers compelling opportunities, investors must be mindful of several risks:

• High valuations: Stocks like HAL, with price-to-earnings ratios near 40x, may be overvalued, potentially leading to price corrections if market sentiment shifts.
  
  

• Geopolitical risks: Regional tensions, such as India-Pakistan conflicts, can influence defence budgets and stock prices, creating volatility.

  
  

• Dependence on government budgets: The sector’s growth is heavily tied to government spending, which can be affected by shifts in political or economic priorities.
  
  

• Cyclical performance: defence stocks may underperform during periods of reduced geopolitical tensions, as government priorities shift toward other sectors.
  
  

• Ethical considerations: Some investors may have reservations about supporting the military-industrial complex, impacting investment decisions.

To mitigate these risks, investors should conduct thorough due diligence, focusing on companies with strong fundamentals and diversified revenue streams.

Lessons from mature markets

India can draw valuable insights from mature defence markets like the United States to refine its investment strategies:

• Stable contracts: US defence firms like Lockheed Martin benefit from long-term, multi-year government contracts that ensure predictable revenue streams. India could adopt similar contract structures to provide stability for its defence companies.

  
  

• Diversified exposure: Exchange-traded funds (ETFs) like the iShares U.S. Aerospace & defence ETF allow investors to spread risk across multiple companies, reducing exposure to individual stock volatility. India’s emerging defence ETFs, such as the Motilal Oswal Nifty India Defence ETF and Groww Nifty India Defence ETF FoF, offer similar diversification opportunities.
  
  

• Focus on fundamentals: Long-term investors in mature markets prioritise companies with strong balance sheets, consistent earnings, and diversified portfolios. Indian investors can apply this approach to avoid speculative risks and focus on sustainable growth.

By adopting these strategies, India can enhance the resilience and attractiveness of its defence sector for both domestic and international investors.

The road ahead

India’s defence sector stands at a pivotal juncture, driven by technological innovation, substantial government investment, and a steadfast commitment to self-reliance. The sector’s growth trajectory offers significant opportunities for investors, from high-performing stocks like HAL, BEL, and BDL to emerging defence ETFs that provide diversified exposure. However, risks such as high valuations, geopolitical uncertainties, and dependence on government budgets require careful navigation.

By learning from mature markets, India can implement strategies like stable, long-term contracts and diversified investment vehicles to maximise growth and stability. As the country continues to modernise its armed forces and expand its global defence footprint, the sector is poised to contribute significantly to both national security and economic development.
