What Happened

  • The Defence Acquisition Council (DAC), chaired by Defence Minister Rajnath Singh, cleared acquisition proposals worth approximately Rs 2.38 lakh crore on March 27, 2026.
  • Five additional squadrons of the S-400 'Sudarshan' long-range surface-to-air missile system were approved for procurement from Russia — building on the existing five-squadron contract signed in 2018.
  • A follow-on order for 300 units of the Dhanush 155mm/45-calibre indigenous artillery gun system was cleared to equip 15 artillery regiments, adding to the 114 guns already in service.
  • Medium Transport Aircraft were approved to replace the ageing Antonov An-32 and Ilyushin IL-76 fleets for the Indian Air Force, covering strategic, tactical, and operational airlift roles.
  • The clearances also included Ghatak unmanned combat aerial vehicles (UCAVs) and BrahMos cruise missiles, reflecting a broad multi-domain procurement push.
  • The approvals come after the S-400 'Sudarshan Chakra' batteries proved effective in neutralising Pakistani aerial threats during May 2025, significantly raising political and strategic confidence in the system.

Defence Acquisition Council (DAC) and the Procurement Approval Chain

The DAC is the apex body for defence procurement in India, headed by the Defence Minister and comprising the three service chiefs, the Chief of Defence Staff, the Defence Secretary, and other senior officials. It grants Acceptance of Necessity (AoN) — the formal trigger that starts a procurement cycle — for capital acquisitions above a threshold. For strategically sensitive or high-value procurements, the DAC's AoN is followed by approval from the Cabinet Committee on Security (CCS), which is chaired by the Prime Minister. Contract signing happens only after both these gates are cleared.

  • DAC grants AoN (Acceptance of Necessity) — the first formal approval in the procurement lifecycle.
  • CCS approval required for high-value and strategically sensitive deals.
  • Governed by the Defence Acquisition Procedure (DAP) 2020, which replaced the DPP 2016.
  • Procurement categories: Buy (Indian-IDDM), Buy (Indian), Buy & Make (Indian), Buy & Make, Buy (Global).
  • Buy (Indian-IDDM) has the highest priority — indigenously designed, developed, and manufactured with ≥50% indigenous content.

Connection to this news: The Rs 2.38 lakh crore DAC clearance is at the AoN stage; deals of this magnitude, especially the foreign-origin S-400 procurement, will subsequently require CCS approval before contracts are signed.

S-400 Triumf ('Sudarshan Chakra') — India's Long-Range Air Defence Backbone

The S-400 Triumf (NATO reporting name: SA-21 Growler) is a Russian-origin long-range surface-to-air missile system developed by Almaz-Antey. India signed a $5.43 billion contract with Russia in October 2018 for five squadrons, making it one of the largest defence deals India has ever signed. The system is called 'Sudarshan Chakra' in Indian service. Three of the five contracted squadrons have already been delivered, with deliveries of the remaining two delayed partly due to the Russia-Ukraine war disrupting Russian defence production schedules.

  • Range: up to 400 km; engagement altitude: up to 30 km.
  • Can simultaneously track up to 80 targets and engage up to 36 targets at once using four types of missiles.
  • Maximum missile speed: ~17,000 km/h (approximately Mach 14).
  • Effective against aircraft, ballistic missiles, cruise missiles, and drones.
  • India's purchase triggered U.S. concerns under CAATSA (Countering America's Adversaries Through Sanctions Act); the U.S. waived sanctions in India's case given its strategic importance.

Connection to this news: The fresh DAC clearance for five additional S-400 squadrons would effectively double India's contracted inventory, representing a major expansion of the multi-layered air defence grid — a strategic priority reinforced by the system's operational success in May 2025.

Dhanush Howitzer — India's Indigenous Artillery Modernisation

The Dhanush is a 155mm/45-calibre towed howitzer manufactured at Gun Carriage Factory, Jabalpur under Advanced Weapons and Equipment India Limited. It is an indigenously upgraded and evolved version of the Swedish Bofors FH77B howitzer, with the barrel lengthened from 39 to 45 calibres and fitted with an inertial navigation-based sighting system, auto-laying facility, onboard ballistic computation, and advanced day-night direct firing capability. It was approved for series production in 2019 with over 80% indigenous content.

  • Calibre: 155mm/45-calibre; chamber capacity: 23 litres.
  • Maximum range: over 36 km (38 km in plains); Bofors original could not exceed 27 km effectively.
  • Rate of fire: 3 rounds in 30 seconds (burst); 12 rounds in 3 minutes (intense).
  • Compatible with ERFB BB, ERFB BT, HEER, HE, Smoke, and Illumination ammunition.
  • 114 guns already in service; fresh order of 300 would equip 15 additional artillery regiments.

Connection to this news: The 300-gun Dhanush order reflects India's artillery modernisation programme, replacing Cold War-era 105mm and 122mm Russian guns with a 155mm NATO-standard weapon built domestically — aligning with Aatmanirbhar Bharat in defence.

Medium Transport Aircraft — Filling the IAF Airlift Gap

The Indian Air Force's transport fleet is ageing significantly. The Antonov An-32 (inducted in the 1980s) and Ilyushin IL-76 (inducted since 1985) form the backbone of tactical and strategic airlift respectively but face obsolescence and maintenance challenges, especially given the Russia-Ukraine war's impact on spares supply chains. The Medium Transport Aircraft (MTA) requirement seeks a replacement capable of fulfilling inter-theatre mobility, logistics, paradrop, and humanitarian airlift roles across India's diverse terrain — from high-altitude Himalayan forward bases to island territories.

  • The IAF currently operates approximately 105 An-32s (under an upgrade programme) and 11 IL-76s.
  • The MTA requirement was earlier explored as a joint Indo-Russian AVIC project but did not materialise.
  • Transport aircraft procurement falls under IAF's essential force structure requirements alongside combat aircraft.
  • Airlift capacity is critical for rapid deployment in Himalayan sectors and for HADR (Humanitarian Assistance and Disaster Relief) operations.

Connection to this news: The DAC clearance for new transport aircraft sets the stage for replacing the An-32/IL-76 fleets, with a possible mix of foreign and indigenous options, given the government's emphasis on Buy (Indian) categories wherever feasible.

Key Facts & Data

  • Rs 2.38 lakh crore: total value of proposals cleared by DAC on March 27, 2026 — one of the largest single-day procurement clearances in Indian defence history.
  • India's original S-400 contract (2018): $5.43 billion for five squadrons; fresh clearance would add five more.
  • 3 of 5 contracted S-400 squadrons already delivered; 4th expected by May 2026.
  • 300 additional Dhanush guns approved; 114 already in service with Indian Army.
  • Dhanush range: over 36 km — exceeding original Bofors FH77B range by ~10 km.
  • CAATSA risk: U.S. law targets countries buying major Russian defence systems; India has so far received a waiver.
  • DAP 2020 gives highest priority to Buy (Indian-IDDM) category to promote indigenous defence manufacturing.
