What Has the Defence Acquisition Council Announced?
The DAC granted AoN to capital acquisition proposals estimated at approximately ₹2,12,000 crore. The approvals cover requirements across all three services.
The main areas include:
- Indian Army: High Mobility Vehicles, Self-Propelled Tracked Gun Systems, Light Multi Role Helicopters, Very Short-Range Air Defence Systems, counter-unmanned aerial systems, surveillance UAVs and other surveillance and strike capabilities.
- Indian Navy: Active Offboard Decoy Systems and other major naval platforms, including indigenously designed and constructed platforms.
- Indian Air Force: Helicopters, air-defence systems, weapons and Mobile X-Band Doppler Weather Radar Systems.
These proposals are intended to strengthen operational mobility, firepower, surveillance, air defence and protection against evolving threats.
The ministry also stated that approximately 82% of the proposed procurements would be sourced from Indian industry, highlighting the importance of domestic manufacturing in the acquisition plan.
What Is the Defence Acquisition Council?
The Defence Acquisition Council is the apex defence procurement decision-making body within the Ministry of Defence. It is chaired by the Defence Minister and considers major acquisition proposals for the armed forces.
Its role is to assess defence capability requirements and take decisions at important stages of the acquisition process.
The DAC is relevant to India’s efforts to modernise its armed forces, improve operational preparedness and strengthen domestic defence production.
What Does Acceptance of Necessity (AoN) Mean?
Acceptance of Necessity is an important preliminary approval in the defence acquisition process. It indicates that a proposed capability requirement has received in-principle administrative approval to proceed through the prescribed procurement process.
However, AoN does not mean that a final procurement contract has been signed, that all equipment has been ordered, or that the entire estimated amount has already been spent.
Further steps may include detailed procurement procedures, evaluation, negotiations, financial approvals where required, contract award, production and delivery. The exact path depends on the applicable procurement category and rules.

Why Does India Need Defence Modernisation?
India faces a complex security environment involving land borders, maritime interests, aerial threats and rapidly changing military technologies. Modernisation is necessary to ensure that the armed forces can respond effectively to conventional and emerging challenges.
1. Improving Mobility and Operational Readiness
High Mobility Vehicles can support logistics and movement in challenging terrain. Mobile artillery systems can combine mobility with firepower, while helicopters can support reconnaissance, surveillance, transport, search and rescue, and other operational requirements.
Modern equipment is most effective when accompanied by trained personnel, maintenance support, reliable supply chains and appropriate operational planning.
2. Responding to Drone Warfare
Unmanned aerial systems have become increasingly significant in modern conflicts. They can be used for surveillance, reconnaissance, targeting and, in some cases, attack missions.
Counter-unmanned aerial systems aim to detect, track or neutralise hostile drones. Very short-range air-defence systems can help address certain short-range aerial threats.
India’s security preparedness therefore requires a layered approach combining detection, electronic warfare where appropriate, kinetic interception, intelligence and coordinated command systems.
No single technology can address every aerial threat, and effectiveness depends on the nature of the threat and the system’s operational integration.
3. Strengthening Maritime Security
The Indian Navy protects maritime interests, supports sea-lane security and contributes to regional stability.
An Active Offboard Decoy System is designed to help protect ships by drawing or diverting certain incoming missile threats away from the vessel. Its effectiveness depends on the threat, system design and integration with other defensive measures.India-China Border Tensions Persist: ITBP Boosts Security Along Arunachal Pradesh
The proposed naval acquisitions are intended to strengthen maritime combat capabilities and improve preparedness against evolving threats.
4. Enhancing Air Defence and Surveillance
Air-defence systems help detect and respond to aerial threats. Surveillance systems provide information that supports situational awareness and operational decisions.
Mobile X-Band Doppler Weather Radar Systems can provide high-resolution, localised weather surveillance in forward areas. Weather information can be important for military planning and the safe conduct of operations.
Modern defence preparedness increasingly depends on integrating sensors, communication networks, command systems and trained personnel.
Why Is the 82% Domestic Sourcing Figure Important?
The Ministry of Defence stated that approximately 82% of the proposed procurements would be sourced from Indian industry. This emphasis is relevant to the broader goal of strengthening India’s domestic defence industrial base.
Benefits for India
1. Industrial development: Domestic sourcing can create opportunities for manufacturers, component suppliers, maintenance providers and other parts of the defence supply chain.
2. Technological capability: Sustained demand can encourage research, design, testing and production capabilities within India.
3. Supply-chain resilience: Domestic production may reduce some external dependencies, particularly when supported by reliable access to critical components and materials.
4. Skilled employment: Defence manufacturing can support specialised jobs in engineering, electronics, software, metallurgy, precision manufacturing and maintenance.
5. Lifecycle support: Local repair, maintenance and spare-parts capacity can contribute to equipment availability over its service life.
However, domestic sourcing does not automatically guarantee complete technological self-reliance. Imported components, specialised materials, intellectual property, testing capacity and production scale can remain important constraints.
The long-term objective should be to deepen Indian design and manufacturing capabilities, improve quality and reliability, and build globally competitive defence supply chains.
Atmanirbhar Bharat and Defence Manufacturing
Atmanirbhar Bharat aims to strengthen domestic capabilities across sectors, including defence. In defence production, self-reliance involves more than assembling equipment within the country.
A stronger domestic ecosystem requires progress in:
- Research and development.
- Design and engineering.
- Electronics, sensors and advanced materials.
- Engines and propulsion systems.
- Software, artificial intelligence and secure communications.
- Testing, certification, maintenance and upgrades.
- Partnerships among public-sector enterprises, private firms, start-ups and research institutions.
Government procurement can provide demand and scale, but successful indigenisation also depends on competition, innovation, predictable procurement processes and effective project management.
Challenges in Defence Procurement
Large defence acquisition programmes can improve capabilities, but their success depends on execution.
1. Delays and Cost Escalation
Complex projects may face delays in testing, production, negotiations, infrastructure development or supply-chain delivery. Delays can postpone capability improvements and increase overall costs.
2. Dependence on Imported Components
Even equipment produced domestically may rely on imported engines, chips, specialised materials or subsystems. Reducing critical dependencies requires long-term investment and technological development.
3. Integration and Interoperability
New platforms must work effectively with existing equipment, communications systems and command structures. Poor integration can limit the operational value of otherwise capable systems.
4. Maintenance and Lifecycle Costs
The purchase price is only one part of the total cost of defence equipment. Training, spare parts, maintenance, upgrades and eventual replacement also require planning.
5. Balancing Modernisation with Fiscal Priorities
Defence preparedness is essential, but capital expenditure must be managed alongside other public priorities. Procurement decisions should reflect strategic requirements, affordability and long-term operational needs.
Way Forward
India can improve the outcomes of defence modernisation through a combination of strategic planning and industrial development.
- Prioritise critical capabilities: Acquisition decisions should be linked to clearly assessed operational requirements.
- Deepen domestic design capability: Encourage Indian research, development and production rather than relying only on local assembly.
- Improve procurement execution: Strengthen project monitoring, testing, quality assurance and contract management.
- Support innovation: Build effective partnerships between the armed forces, public-sector manufacturers, private companies, start-ups and academic institutions.
- Plan for the full lifecycle: Include training, maintenance, upgrades and supply-chain resilience in acquisition planning.
- Promote responsible competition: Transparent and predictable procurement processes can improve value for money and industrial confidence.
- Measure results: Evaluate modernisation through delivery, availability, reliability, operational integration and measurable capability improvements—not only the announced value of proposals.
Conclusion
The Defence Acquisition Council’s in-principle approval of proposals worth approximately ₹2.12 lakh crore highlights India’s continuing focus on defence modernisation and domestic industrial capacity.
The proposals cover capabilities relevant to land mobility, surveillance, counter-drone operations, air defence and maritime security. The stated emphasis on sourcing around 82% of the proposed procurements from Indian industry also underlines the relationship between national security and domestic manufacturing.
However, the real impact will depend on subsequent procurement decisions, timely delivery, technological capability, maintenance and effective integration into the armed forces.
For India, the objective should be to build a force that is operationally prepared, technologically capable and supported by a resilient domestic defence ecosystem.

Mains Practice Question
Q. “Defence indigenisation is essential for strategic autonomy, but domestic sourcing alone cannot guarantee self-reliance.” Discuss in the context of India’s recent defence acquisition proposals. (150 words)
Model Answer
Defence indigenisation can strengthen strategic autonomy by developing domestic manufacturing, reducing selected external dependencies and supporting technological innovation. The Defence Acquisition Council’s October 2026 in-principle approval of proposals worth approximately ₹2.12 lakh crore, with around 82% of proposed procurements to be sourced from Indian industry, reflects this objective.
Domestic sourcing can create industrial opportunities, skilled employment and local maintenance capabilities. It can also support research and development in areas such as electronics, surveillance, air defence and unmanned systems.
However, local sourcing does not automatically ensure complete self-reliance. Critical components, specialised materials, engines and intellectual property may still depend on external sources. Procurement delays, cost escalation and weak integration can also reduce the benefits of investment.
India should therefore move beyond assembly towards indigenous design, research, testing and lifecycle support. Stronger collaboration among the armed forces, industry, start-ups and research institutions is essential.
Thus, domestic sourcing is an important step, but genuine strategic autonomy requires technological depth, reliable production, quality assurance and effective delivery.
