GS Paper III: Security, Defence Technology and Indigenisation

What is the Defence Acquisition Council (DAC)?
- It is the Ministry of Defence's apex decision-making body for major defence capital acquisitions.
- It was established in 2001 following the recommendations of the Group of Ministers on national security after the Kargil conflict.
- Its principal role is to facilitate the acquisition of military equipment and capabilities required by the armed forces, while supporting defence preparedness, procurement planning and indigenisation.
Major Defence Procurement Proposals
- Indian Army: Mobility, Firepower and Drone Warfare
- The Army's approved proposals focus on improving the mobility of troops, artillery capabilities, protection against aerial threats and battlefield surveillance.
- High Mobility Vehicles (HMVs): These vehicles are intended to improve troop movement, transportation of supplies and logistical support in difficult terrain, including operationally challenging areas.
- Self-Propelled Tracked Gun System: A mobile artillery capability designed to provide mechanised formations with greater mobility and firepower.
- Light Multi-Role Helicopters (LMRH): These helicopters are intended for use by both the Army and the Air Force in reconnaissance, surveillance, combat support, troop search and rescue, and humanitarian assistance and disaster relief (HADR).
- Very Short-Range Air Defence System (VSHORADS): Designed to engage small, low-altitude aerial threats, these systems can contribute to the protection of troops and military assets against emerging air threats.
- Platform-Based Counter-UAS System: Counter-Unmanned Aerial Systems (C-UAS) are intended to counter hostile drones and improve the survivability of tanks on the modern battlefield.
- Surveillance and Strike Drone Systems: The proposals include a long-range Unmanned Aerial System, surveillance UAVs, an Integrated Surveillance and Strike System and a Long-Range Kamikaze Drone System.
- Indian Navy: Protection Against Anti-Ship Missiles
- The DAC approved procurement proposals for an Active Offboard Decoy System and other major naval platforms.
- The AODS is intended to strengthen the Navy's anti-missile defence, particularly against modern anti-ship missiles.
- An offboard decoy is deployed away from the protected ship to divert or confuse an incoming missile's targeting system.
- An active decoy can use an emitted or generated signal to imitate or manipulate the target's signature, depending on the system's design.
- The operational significance is that naval vessels face threats from increasingly sophisticated anti-ship missiles.
- Decoy systems can form one layer of a ship's wider defensive architecture, alongside detection, electronic warfare and other defensive measures.
- Indian Air Force: Air Defence, Helicopters and Weather Surveillance
- Helicopters and Air Transport: The proposals include Special Utility Helicopters to meet important air transport requirements, along with other helicopter procurement proposals.
- Air Defence Systems and Weapons: The proposed acquisitions are intended to improve the Air Force's air-defence capabilities and overall war-fighting preparedness.
- Mobile X-Band Doppler Weather Radar System: This system will provide high-resolution, localised weather surveillance in forward areas, helping improve the availability of weather information for operational planning.
What is Acceptance of Necessity (AoN)?
- An in-principle administrative approval for a proposed defence acquisition.
- It establishes that the procurement requirement can proceed to subsequent stages under the applicable acquisition framework.
- It is essential to distinguish AoN from a signed procurement contract.
Defence procurement: Simplified sequence
- Identification of military requirement
- Acceptance of Necessity (AoN)
- In-principle administrative approval
- Detailed procurement process
- Tender or request for proposal, as applicable; technical evaluation and trials where required
- Commercial evaluation and contract negotiations
- Contract award, production and delivery
Why is the 82% Domestic Procurement share important?
- Defence indigenisation: Domestic sourcing can encourage Indian manufacturers to develop and produce military equipment, components and supporting technologies.
- Reduced import dependence: Greater domestic capacity can reduce exposure to external supply disruptions, export restrictions and geopolitical uncertainties. However, the degree of import reduction depends on the actual indigenous content and supply chains of each system.
- Technology development: Defence production can support engineering, electronics, sensors, communications, aerospace, robotics and materials research.
- Employment and industrial development: Procurement may create opportunities for skilled employment and for micro, small and medium enterprises (MSMEs) participating in defence supply chains.
- Maintenance and lifecycle support: Local manufacturing and technical capabilities can improve access to repairs, spare parts, upgrades and long-term equipment support.
- Strategic autonomy: A stronger domestic industrial base can improve India's ability to sustain military operations without excessive dependence on foreign suppliers.

Significance for India's National Security
- Preparedness for modern warfare: The proposals reflects the growing importance of combining conventional military strength with modern sensors, drones and electronic systems.
- Strengthening border operations: High-mobility vehicles, helicopters, surveillance platforms and short-range air defence systems can support operations in difficult terrain.
- Countering emerging aerial threats: Small drones and unmanned systems have become important tools for surveillance, reconnaissance and attack.
- Enhancing maritime security: The proposed naval decoy systems and other naval platforms can strengthen the Navy's ability to protect vessels and sustain operations in a maritime environment where anti-ship missiles pose a serious threat.
- Promoting joint operational capabilities: Effective coordination among the three services can improve operational support and resource utilisation.
Challenges in India's Defence Procurement
- Procurement delays: Complex technical assessments, trials, negotiations and contracting can extend the time between initial approval and delivery.
- Cost and time overruns: Changes in specifications, supply-chain disruptions and development difficulties can increase costs or delay induction.
- Quality and reliability: Military equipment must meet demanding performance, safety and reliability standards under varied operational conditions.
- Integration across services: Equipment must work effectively with existing communications, surveillance, command-and-control and weapon systems.
- Industrial capacity: Domestic firms must possess adequate production capacity and skilled manpower to meet defence requirements without compromising quality.
