DAC clears Rs 2.38 lakh crore defence proposals

Acceptance of Necessity granted for major Army, Air Force and Coast Guard acquisitions, including the S-400 long-range surface-to-air missile system.

What happened

The Defence Acquisition Council (DAC), the apex capital-procurement clearing body of the Ministry of Defence, met on 27 March 2026 under the chairmanship of Raksha Mantri Rajnath Singh.
It granted Acceptance of Necessity (AoN) for a clutch of proposals worth an estimated Rs 2.38 lakh crore, spanning all three services that procure through it — the Army, the Air Force and the Coast Guard.
For the Indian Army: an Air Defence Tracked System, Armoured Piercing Tank Ammunition, High Capacity Radio Relay, the Dhanush Gun System, and a Runway Independent Aerial Surveillance System.
For the Indian Air Force: Medium Transport Aircraft (to replace the AN-32 and IL-76 fleet), the S-400 Long Range Surface-to-Air Missile System, Remotely Piloted Strike Aircraft, and overhaul of Su-30 aero-engine aggregates.
For the Indian Coast Guard: Heavy Duty Air Cushion Vehicles (hovercraft) for high-speed coastal patrol, reconnaissance and search-and-rescue.
AoN is the first formal stage of the capital-acquisition pipeline — an in-principle clearance of the requirement, not a signed contract or a delivery commitment.

Background & context

The Defence Acquisition Council was constituted in 2001, in the wake of the Kargil Review Committee's findings and the Group of Ministers' report on reforming national security management, to give defence procurement a single, high-level decision-making forum. It is the highest body in the Ministry of Defence for deciding on capital acquisitions for the three armed services and the Indian Coast Guard. It is chaired by the Defence Minister (Raksha Mantri), and its members include the Chief of Defence Staff, the three Service Chiefs, the Defence Secretary, the Secretary (Defence Production), the Secretary (Defence R&D)/DRDO chief, the Secretary (Defence Finance) and other senior officials. Its mandate is to ensure that acquisitions flow expeditiously within approved budgets and follow the procedures laid down in the Defence Acquisition Procedure (DAP) 2020 — the rulebook that replaced the earlier Defence Procurement Procedure (DPP) and which prioritises indigenous design and manufacture under the Atmanirbhar Bharat (self-reliance in defence) policy.

Capital procurement under the DAP moves through a defined sequence: the AoN clearance considered here is only the opening gate. After AoN, the case proceeds to a Request for Proposal (RFP) issued to vendors, then field evaluation trials, staff evaluation, commercial negotiation by a Contract Negotiation Committee, and finally Cabinet Committee on Security (CCS) approval for high-value cases before a contract is signed and deliveries begin. Each AoN is also tagged to an acquisition category — the order of preference under DAP 2020 runs Buy (Indian-IDDM, i.e. Indigenously Designed, Developed and Manufactured), then Buy (Indian), Buy and Make (Indian), Buy and Make, and lastly Buy (Global), with Buy (Global – Manufacture in India) added to pull foreign platforms into domestic production. Understanding that AoN sits at the top of this funnel is the single most exam-relevant idea in this release: an AoN figure is a statement of intent and ceiling cost, not money spent.

For Prelims

Decision body: Defence Acquisition Council (DAC) — apex capital-acquisition body of the Ministry of Defence, set up in 2001, chaired by the Raksha Mantri.
Acceptance of Necessity (AoN): the first-stage, in-principle approval of a procurement case under the Defence Acquisition Procedure (DAP) 2020; it precedes the RFP, trials, negotiation and contract.
Headline figure: AoN of about Rs 2.38 lakh crore granted on 27 March 2026 across the Army, Air Force and Coast Guard.
S-400 Triumf: a Russian-origin long-range, surface-to-air missile (SAM) air-defence system meant to counter enemy long-range air vectors (aircraft, cruise missiles, drones) targeting vital areas; in Indian service it is referred to by the codename Sudarshan Chakra.
Dhanush Gun System: India's first indigenous long-range 155 mm / 45-calibre towed artillery gun, derived from the Bofors design and developed by the Ordnance Factory Board (now under the defence PSU family); it improves range, lethality and accuracy across terrains.
Air Force airlift: the new Medium Transport Aircraft is to replace the ageing AN-32 and IL-76 transport fleet, covering strategic, tactical and operational airlift.
Coast Guard: Heavy Duty Air Cushion Vehicles (hovercraft) for high-speed coastal patrol, reconnaissance, and search-and-rescue (SAR).
Other Army items: Air Defence Tracked System (real-time air-defence control and reporting), High Capacity Radio Relay (fail-proof communication), Runway Independent Aerial Surveillance System, and Armoured Piercing Tank Ammunition.
Other Air Force items: Remotely Piloted Strike Aircraft (offensive counter-air and stealth ISR) and overhaul of Su-30 aero-engine aggregates to extend service life.
FY 2025-26 record: AoN for 55 proposals worth Rs 6.73 lakh crore, and capital procurement contracts signed for 503 proposals worth Rs 2.28 lakh crore — both stated to be the highest in any financial year.

What it is NOT. An AoN is not a signed contract, not a budget release, and not a guarantee that the platform will be inducted — many AoNs lapse if not progressed in time. The DAC is not the Cabinet Committee on Security (CCS): the CCS gives final political clearance to high-value contracts, while the DAC clears the requirement and the procurement route. The DAC is also not the Defence Procurement Board or the Defence Production & Acquisition Wing; it is the apex council that those bodies feed into. The S-400 is a surface-to-air (air-defence) system, not a surface-to-surface or ballistic-missile strike weapon, and not an indigenous platform. The Dhanush is a towed gun, distinct from the tracked, self-propelled K-9 Vajra and from the ATAGS (Advanced Towed Artillery Gun System) developed by DRDO.

The full procurement-stage set (so "arrange in order" questions survive): AoN → RFP → field/staff evaluation → commercial negotiation (CNC) → CCS/competent-authority approval → contract signing → delivery. The acquisition categories under DAP 2020 in order of preference: Buy (Indian-IDDM) · Buy (Indian) · Buy and Make (Indian) · Buy and Make · Buy (Global – Manufacture in India) · Buy (Global). India's artillery family for pairing questions: Dhanush (indigenous towed 155 mm), ATAGS (DRDO towed), K-9 Vajra (tracked self-propelled), M777 (imported ultra-light howitzer), Sharang (upgraded 130 mm to 155 mm).

For UPSC: The DAC grants Acceptance of Necessity (AoN) — the first approval stage of capital procurement under DAP 2020, not a signed contract. The S-400 is a Russian long-range surface-to-air missile system (Indian codename Sudarshan Chakra); the Dhanush is India's indigenous 155 mm towed artillery gun.

Why it matters

The package reads as a snapshot of India's force-modernisation priorities along all three classic domains of conventional deterrence — land, air and the maritime coastal periphery. The recurring theme is capability gaps the forces have flagged for years: the AN-32/IL-76 replacement addresses a thinning strategic-airlift fleet; the S-400 and Air Defence Tracked System harden multi-layered air defence against drones, cruise missiles and stand-off vectors, a lesson sharpened by recent conflicts; the Dhanush and armour-piercing ammunition deepen artillery and anti-tank lethality along contested land borders; and the Coast Guard hovercraft extend reach into shallow, creek-laced coastlines where conventional ships cannot operate. The release also doubles as a self-reliance and defence-economy story: by routing requirements through the DAC under DAP 2020, the state both signals demand to domestic industry and channels record capital outlays — the stated FY 2025-26 figures of Rs 6.73 lakh crore in AoNs and Rs 2.28 lakh crore in signed contracts frame defence acquisition as an instrument of industrial policy as much as of security. For an aspirant, the deeper point the release makes is procedural literacy: knowing that an AoN headline number is the start of a multi-year pipeline guards against over-reading a press figure as delivered capability.

For Mains

Data

India's capital-acquisition machinery in FY 2025-26 — AoN for 55 proposals worth Rs 6.73 lakh crore and contracts for 503 proposals worth Rs 2.28 lakh crore (both record highs) — is hard, citable evidence of the scale and acceleration of defence modernisation under the indigenisation push.

Exemplification

The 27 March 2026 AoN basket (S-400, Medium Transport Aircraft, Dhanush, hovercraft, Remotely Piloted Strike Aircraft) is a ready illustration of how the DAC and DAP 2020 translate service requirements into procurement across land, air and maritime domains.

Position

Routing a mixed import-and-indigenous basket through the DAC reflects the government's stated stance of balancing urgent operational needs (S-400, transport aircraft) with Atmanirbhar Bharat self-reliance (Dhanush, indigenous systems).

Problematisation

That AoN is only the opening gate — and that AoNs can lapse before contracting — surfaces the perennial Mains theme of procurement delays, single-vendor situations and the long lead time from "necessity accepted" to "capability inducted".

Deploys into: defence modernisation and procurement reform; indigenisation of defence production (Atmanirbhar Bharat in defence); India's air-defence and external-security preparedness; the institutional architecture of national-security decision-making.
