The Department of Defence Production, Ministry of Defence has notified the sixth Positive Indigenisation List, covering 405 strategically important items with an estimated business potential of ₹3,070 crore.
The list comprises Line Replaceable Units, sub-systems, sub-assemblies, spares, components and raw materials — 16 items belonging to the Indian Coast Guard and 389 to Defence Public Sector Undertakings.
Items span the Advanced Light Helicopter, Light Utility Helicopter, Su-30MKI, Light Combat Aircraft and AL-31FP engine, the T-72, T-90 and BMP-II armoured platforms, warships, the Konkurs-M, Invar and MRSAM missile systems, radars, sonars, fire control and satellite communication systems, and High Explosive Anti-Tank ammunition.
Each item carries an indicative indigenisation timeline and is listed on the SRIJAN portal; once developed domestically it will be procured from Indian industry, with DPSUs and the Coast Guard using the 'Make' procedure and in-house development, and MSMEs expected to participate.
SRIJAN, launched in August 2020, has carried offers of more than 33,000 defence items up to June 2026, including 5,012 under the first five lists; over 15,700 items have been indigenised, giving import substitution of about ₹9,000 crore over five years.
A Line Replaceable Unit is a modular component designed to be swapped out at the operating base — the flight line — rather than sent to a depot for repair: a radar processor, a hydraulic actuator, an avionics box. Fleets stay flyable only if these units are available, and for imported platforms such as the Su-30MKI or the T-90 they have historically come from the original supplier, which means long lead times, foreign-exchange outflow and exposure to sanctions or a supplier's shifting priorities. Indigenising an LRU does not build a new fighter, but it makes the existing fleet sustainable and creates a repeatable order book that MSMEs can actually serve. That is why a list of 405 spares, sub-assemblies and raw materials worth ₹3,070 crore matters more than its rupee value suggests: the value is in fleet availability and in the industrial base it seeds.
Simple Analogy: It is the difference between manufacturing cars and manufacturing the spare parts that keep imported cars on the road. The second is less glamorous and decides whether the fleet moves.
Progressively stop imports of components, spares and sub-systems used by DPSUs and Service Headquarters.
Key: Six lists so far; the first five carried 5,012 items and the sixth adds 405 items worth ₹3,070 crore, each with an indicative indigenisation timeline after which it is bought from Indian industry.
Match items DPSUs and Service Headquarters want indigenised with Indian firms able to make them.
Key: Launched by DDP in August 2020 at srijandefence.gov.in; more than 33,000 items offered up to June 2026, with over 15,700 indigenised.
Fund or facilitate indigenous design and development of defence equipment by Indian industry.
Key: DAP 2020 created procurement categories that give preference to indigenous design, development and manufacture; the DPSUs and the Coast Guard will use the Make route and in-house development for these items.
Bring start-ups, MSMEs, individual innovators and academia into defence and aerospace technology development.
Key: Launched on 12 April 2018 at DefExpo in Chennai and run through the Defence Innovation Organisation, a Section 8 company funded by Hindustan Aeronautics Limited and Bharat Electronics Limited.
Department of the Ministry of Defence responsible for indigenous production of defence equipment, the DPSUs and Ordnance Factory Board successor companies, and this series of indigenisation lists; it runs the SRIJAN portal.
Government-owned defence manufacturers that own 389 of the 405 items on this list and place orders on domestic vendors — about ₹10,000 crore up to March 2026.
Armed force of the Union for maritime law enforcement, search and rescue and coastal security, functioning under the Ministry of Defence; 16 items on this list are its.
Not-for-profit company that executes the iDEX framework, funding start-ups and MSMEs working on defence problem statements.
Indigenisation lists, the raised FDI cap in defence, corporatisation of the Ordnance Factory Board and defence industrial corridors are the standard set of measures cited together on this theme.
Components and spares are the segment MSMEs can realistically supply, so a list of LRUs and sub-assemblies is industrial policy for small enterprises as much as defence policy.
The Su-30MKI, AL-31FP engine, T-72, T-90, BMP-II, Konkurs-M and Invar on this list are all of Soviet or Russian origin, which is why spares indigenisation is framed as a strategic-autonomy question.
The Coast Guard's presence on a production list connects to coastal security architecture after 26/11, its role under the Coast Guard Act, 1978 and its distinction from the Indian Navy.
A deeper component base is the precondition for the ₹50,000 crore defence export target by 2029, alongside annual production of ₹3 lakh crore.
