Defence Acquisition Council clears proposals worth about ₹2.12 lakh crore
The Defence Acquisition Council (DAC), chaired by Raksha Mantri Rajnath Singh, gave Acceptance of Necessity (AoN) on 26 October 2026 to capital acquisition proposals worth about ₹2,12,000 crore for the three Services. The ministry says about 82% of these procurements will be made from Indian industry.
Background
An AoN is the in-principle approval that starts a capital acquisition; it is not yet a contract.
For the Army the list includes high mobility vehicles, a self-propelled tracked gun system, light multi-role helicopters, very short-range air defence systems (VSHORADS), counter-drone systems, surveillance drones and a long-range kamikaze drone system.
For the Navy it includes an Active Offboard Decoy System against anti-ship missiles and indigenously designed major naval platforms.
For the Air Force it includes helicopters, air defence systems, weapons and a mobile X-band Doppler weather radar for forward areas.
Why it matters for the exam
The list is heavy on drones and counter-drone systems, a sign of how recent conflicts have changed what armies buy.
Indigenisation: the 82% figure is the share of procurements from Indian industry, which links the topic to defence self-reliance and the defence industrial base.
Remember the stage: AoN approvals are often reported as 'deals', but contracts, trials and deliveries come later.
For Prelims revision
DAC is chaired by the Raksha Mantri; AoN = Acceptance of Necessity.
26 October 2026 approvals: about ₹2,12,000 crore; about 82% from Indian industry.
Mains practice
Capital acquisitions increasingly favour Indian industry. Examine what this means for self-reliance in defence and what still limits it. (Practice question by Shishya, 250 words)

Flex fuel vehicles: the motor vehicle rules now name E85 and E100
The Ministry of Road Transport and Highways has amended the Central Motor Vehicles Rules, 1989 so that emission certification expressly covers E100 alongside E85, to support flex fuel vehicles that can run on high-ethanol fuels.
Background
E85 is a petrol-ethanol blend with up to 85% ethanol by volume; the number after E is the share of ethanol.
A flex fuel vehicle runs on a range of ethanol-petrol blends from one tank, with engine controls adjusting to the fuel; the release names Brazil and the United States as countries already using the technology.
The fuels are only for vehicles designed and certified for them; being fit for E10 or E20 does not make a vehicle fit for E85.
Owners of existing vehicles are not required to switch fuels or modify their vehicles.
Why it matters for the exam
Energy security: more domestic ethanol can reduce dependence on imported crude oil, as the ministry notes.
Environment: the release says emissions benefits depend on the feedstock and production process, which is the right caution to carry into an answer (food-versus-fuel and water use are the usual counterpoints).
Regulation before markets: rules for certification come first, so that vehicles and fuel pumps can follow.
For Prelims revision
E85 = up to 85% ethanol by volume; E100 = fuel consisting predominantly of ethanol.
Amended: Central Motor Vehicles Rules, 1989 (Ministry of Road Transport and Highways).
Mains practice
Flex fuel vehicles can help India cut crude oil imports. Discuss the conditions under which high-ethanol fuels actually lower emissions. (Practice question by Shishya, 150 words)
