Positive Indigenisation List
A private firm will not spend on developing a part unless it knows the order is waiting, and a Positive Indigenisation List is that assurance written down. The sixth one was notified in August.
- Positive Indigenisation List
- A list of defence items that, after a stated date, the forces may buy only from Indian industry.
- Line replaceable unit
- A module built to be unplugged and swapped where the platform stands, so a repair means changing a unit rather than mending it in place.
- The Department of Defence Production notified the sixth list, of 405 items.
- The 405 are line replaceable units, sub-systems, spares and components rather than whole platforms.
- They fit platforms such as the Light Combat Aircraft (LCA), the Su-30MKI, T-90 tanks and the Medium Range Surface to Air Missile (MRSAM).
- SRIJAN, the defence indigenisation portal, has listed over 33,000 items since 2020, of which over 15,700 are indigenised.
- In the same month the Defence Minister approved transferring the Defence Research and Development Organisation's (DRDO) technologies for all conventional missile systems to Indian industry.

Defence Acquisition Council
Before the armed forces can buy anything large, a council chaired by the Defence Minister has to agree that they need it. The Defence Acquisition Council (DAC) is where a capital purchase is first approved, and what it grants is a decision rather than a payment.
- Acceptance of Necessity
- The first formal step in a defence purchase, accepting the need; requests for proposals, trials and price negotiation follow before any contract.
- Its clearance is the grant of Acceptance of Necessity, which is a decision to buy and not yet money committed.
- In September it cleared proposals worth about ₹1.10 lakh crore, about 98 per cent of it from Indian industry.
- The Army's list runs to Chemical, Biological, Radiological and Nuclear (CBRN) reconnaissance vehicles, the Sarvatra Bridge System and Advanced Light Helicopters.
- The Navy's includes Arudhra radars and marine gas turbines for warship propulsion, to be developed at home.
- The Air Force's includes a ground based multi-purpose jammer against adversaries' radars.
