DAC Approves ₹1.10 Lakh Crore Defence Procurement: India's Largest-Ever Capital Acquisition — CBRN Vehicles, ALH, Sarvatra Bridge and 98% Indigenisation

Why in News

On 7 September 2026, the Defence Acquisition Council (DAC) — India's highest decision-making body for defence procurement — granted Acceptance of Necessity (AoN) for capital acquisition proposals valued at ₹1.10 lakh crore (₹1,10,000 crore). The approvals span all three services — Army, Navy, and Air Force — as well as cross-service electronic warfare and identity systems. Critically, approximately 98% of the approved value is to be sourced from Indian industry, making this one of the most significant single-sitting boosts to domestic defence manufacturing in India's history.

Background

The DAC was constituted in 2001 following the Kargil Review Committee recommendations, with the Defence Minister as its chair. It functions as the apex body of the Defence Acquisition Procedure (DAP) — the codified rulebook for all capital defence procurement. The current edition, DAP 2020, replaced the earlier DPP (Defence Procurement Procedure) and placed greater emphasis on Indian industry participation through categories such as Buy (Indian-IDDM), Buy (Indian), and Make in India.

India spends roughly 2.4% of GDP on defence. However, historically, 60–70% of major equipment was imported, making the country one of the world's largest arms importers. The pivot toward indigenisation accelerated post-2020 under Atmanirbhar Bharat, with a series of Positive Indigenisation Lists (PILs) banning import of specific items after a cut-off date, and a mandatory target of 25% of the defence R&D budget for the private sector.

Current Developments

The September 7, 2026 DAC meeting approved AoN for the following platforms and systems:

Indian Army

• CBRN (Chemical, Biological, Radiological, Nuclear) Recce Vehicles — Specialised platforms for detecting and surviving CBRN environments on the battlefield.
• High Mobility Vehicles — All-terrain tactical vehicles for rapid troop and logistics movement.
• Self-Propelled Mechanical Mine Layers — Automated systems for laying anti-tank mine fields without exposing sappers.
• Advanced Light Helicopters (ALH/Dhruv) — Multi-role helicopters designed by HAL; used for assault, logistics, MEDEVAC, and maritime roles.
• Trawl Tanks — Armoured vehicles fitted with mine-clearing rollers or flails to breach minefields.
• Sarvatra Bridge System — Indigenously developed Rapidly Deployable Road Bridge (RDRB) for crossing water obstacles; designed and built by DRDO and Larsen & Toubro.

Indian Navy

• Arudhra Radars — Medium-power radar systems for air route surveillance; developed by BEL to replace legacy foreign systems.
• Marine Gas Turbines — Propulsion units for warships, reducing dependence on imported turbines from Ukraine and the UK.

Cross-Service Systems

• Ground-Based Multi-Purpose Jammers — Electronic warfare (EW) systems for disrupting enemy radar, communication, and navigation signals.
• DEFSAC (Defence Forces Secure Access Card) — RFID-based smart identity card system replacing paper-based documents for all uniformed personnel across services.

Key Facts

Constitutional Provisions

Article 53 vests the supreme command of the Defence Forces in the President of India. Article 246 read with Seventh Schedule, List I (Union List), Entry 1 places defence of India, including the armed forces, exclusively in Parliament's legislative domain. Article 112 (Annual Financial Statement/Union Budget) governs defence capital expenditure allocations.

Legal Framework

The procurement is governed by the Defence Acquisition Procedure (DAP) 2020, which superseded DPP 2016. The DAP codifies acquisition categories: Buy (Indian-IDDM) — highest preference — requires at least 50% indigenous content with Indigenously Designed, Developed and Manufactured products; Buy (Indian) requires 60% indigenous content. The Positive Indigenisation Lists (PIL) notified under DAP ban imports of specific items after stipulated dates, creating a domestic market.

DRDO operates under the Technology Development Fund (TDF) and Defence Research and Development Organisation Act framework for R&D leading to such procurement.

Institutional Framework

• DAC (Defence Acquisition Council) — Apex body; chaired by the Defence Minister; members include the three Service Chiefs, Chief of Defence Staff (CDS), Defence Secretary, and senior ministry officials.
• Defence Production and Export Promotion Policy (DPEPP) 2020 — Sets the target of a $25 billion defence industry turnover (₹1.75 lakh crore) and $5 billion exports by 2024–25.
• HAL (Hindustan Aeronautics Limited) — Public sector manufacturer of the ALH-Dhruv.
• BEL (Bharat Electronics Limited) — Developer of Arudhra Radar and DEFSAC.
• DRDO — Developed Sarvatra Bridge System and contributes to CBRN platforms.
• iDEX (Innovations for Defence Excellence) — Brings private sector and startups into defence R&D.

Economic Dimensions

India's defence capital budget for 2026–27 is approximately ₹1.72 lakh crore; an AoN of ₹1.10 lakh crore represents a major share. Crucially, these procurements sustain and grow the domestic defence industrial base. The Ordnance Factory Board (now Munitions India Limited, Advanced Weapons and Equipment India Limited, etc.) and private OEMs such as Tata Advanced Systems, L&T, Mahindra Defence, and Data Patterns benefit directly.

The 98% indigenous content target also reduces India's foreign exchange outflow, currently a significant drain on the current account. India's defence exports crossed ₹21,000 crore in 2023–24, and indigenisation of high-value platforms supports this export trajectory.

For Banking/Financial exam angle: Defence spending is fiscal expenditure (capital side) and does not directly create monetary aggregates, but defence PSU stocks (HAL, BEL, DRDO-linked companies) are listed equity instruments; SEBI regulations on government PSU listings apply.

Environmental Dimensions

The Marine Gas Turbines approved for naval warships represent a shift away from imported propulsion systems. Future procurement cycles are expected to integrate hybrid or fuel-cell propulsion as part of India's broader commitment to Net Zero by 2070, though current approvals are for conventional systems.

International Relations

The 98% indigenisation target directly reduces dependence on legacy defence suppliers — particularly Russia (for Army platforms), France (helicopters), and the United Kingdom/Ukraine (marine turbines). This is strategically significant given supply disruptions during the Russia-Ukraine conflict. India's growing defence industrial capacity also underpins the India-US Defence Industrial Cooperation Roadmap, the India-France Horizon 2047 partnership, and the Quad Defence-Industrial Framework.

The CBRN Recce Vehicle approval is also notable in the context of India's obligations under the Chemical Weapons Convention (CWC), where India must maintain credible detection and response capability.

Challenges

• AoN to contract gap: The AoN is only the first step — tendering, evaluation, field trials, negotiations, and contract signing can take 3–7 additional years.
• Technology absorption: For complex platforms like Marine Gas Turbines, India lacks the full ecosystem; partnerships are needed without compromising indigenisation targets.
• Quality and timeliness: Historical delays in HAL's ALH deliveries have frustrated the Army and Navy; scaling up will test production capacity.
• SME participation: While Tier-1 PSUs and large private OEMs benefit, MSMEs in the defence supply chain face capital and certification barriers.

Government Initiatives

• Atmanirbhar Bharat in Defence — Positive Indigenisation Lists, FDI liberalisation (74% automatic, 100% via approval), Defence Industrial Corridors in UP and Tamil Nadu.
• Defence Acquisition Procedure 2020 — Streamlined and preference-ordered procurement categories.
• SRIJAN Portal — Lists 50,000+ import substitution items for domestic industry.
• iDEX (Innovations for Defence Excellence) — Startup and MSME innovation grants for defence R&D.
• Technology Development Fund (TDF) — DRDO grants for private sector R&D.

Way Forward

The Shekatkar Committee (2016) recommended restructuring the defence establishment to enhance operational effectiveness and reduce revenue expenditure to fund capital modernisation. The Kelkar Committee recommended a long-term integrated procurement plan. Going forward, India must:

• Accelerate contract conclusion timelines — the DAC should set mandatory post-AoN milestones.
• Deepen the defence MSME ecosystem through iDEX 2.0 and dedicated defence MSME clusters in the industrial corridors.
• Link defence R&D to academic institutions (as the Kargil Review Committee recommended for civil-military integration).
• Pursue technology transfer (ToT) agreements in Marine Gas Turbines and CBRN detection to build long-term sovereign capability.

FAQ

What is the DAC and who chairs it?

The Defence Acquisition Council (DAC) is the apex body for defence procurement decisions in India, chaired by the Defence Minister. It grants Acceptance of Necessity (AoN) — the first formal approval in the capital procurement cycle.

Does AoN mean a contract has been signed?

No. AoN is only the first administrative step confirming the operational requirement. The actual procurement involves tendering, evaluation, trials, price negotiations, and contract finalisation — a process that can take several more years.

What does 98% indigenous content mean?

It means that approximately 98% of the total procurement value will be paid to Indian companies (public or private sector), rather than to foreign vendors — reducing import dependence and strengthening the domestic defence industrial base.

What is the Sarvatra Bridge System?

Sarvatra is an indigenously developed Rapidly Deployable Road Bridge (RDRB) system, designed by DRDO and manufactured in partnership with Larsen & Toubro, enabling the Army to cross water obstacles and gaps in terrain during operations.
