Defence Component Manufacturing Business: Opportunities for Indian MSMEs

The Indian defence manufacturing sector is not limited only to the manufacturing of fighter jets, warships and missile systems. The success and functioning of all these platforms depend on several small components, precision-engineered parts, electronics and assemblies that make up the platform. With the increasing indigenisation of defence in India, these needs are providing new opportunities to domestic manufacturers, especially to Micro, Small and Medium Enterprises (MSMEs).

Entrepreneurs with engineering and manufacturing expertise can take up defence component manufacturing as an option to join a special industry chain. This guide discusses the components that MSMEs can manufacture, investment required, machinery needed, government schemes to support such businesses, licences and quality certifications required and the procedure to become a defence supplier in India.

Key Takeaways

• Defence indigenisation is creating manufacturing opportunities for MSMEs across aerospace, electronics, naval equipment and precision engineering.
• Small manufacturers can enter the supply chain by producing specialised components and subassemblies.
• Investment requirements vary according to the product category, machinery and quality infrastructure.
• Government initiatives such as iDEX, DRDO's TDF and the SRIJAN portal support defence innovation and domestic sourcing.
• Vendor registration, product qualification and quality assurance are important steps towards securing defence supply orders.

Why India's Defence Industry Needs More MSME Component Manufacturers

The development of India’s defence manufacturing sector is leading to the need for a larger base of suppliers domestically. The need for less reliance on imports and greater local production means there will be a need for manufacturers who can produce everything from precision components to electronic assemblies.

There was an output of defence production to the tune of ₹1.78 lakh crore during FY 2025–26 and defence exports amounted to ₹38,424 crore. The rise is bound to present avenues for domestic parts makers to join in the supply chain process in DPSUs, private defence firms, and OEMs.

The sixth Positive Indigenization List of 405 items with business potential of ₹3,070 crore is another significant development. The positive indigenization list identifies those products and components that will be sourced from within the country, thus giving Indian manufacturers access to the defence supply chain.

The MSMEs are important since large manufacturers of defence products need specialised suppliers for machining, fabrication, electronics, electrical systems and component assembly. In this way, small enterprises will have to produce specific products rather than complete defence platforms.

Defence Components MSMEs Can Manufacture in India

Defence component manufacturing offers opportunities across several engineering and technology categories. MSMEs can focus on specialised products that meet the technical and quality requirements of defence manufacturers rather than investing in the production of complete weapons or military platforms.

Some promising manufacturing categories include:

1. Aerospace Component Parts: Aircraft brackets, structural components, precision machined parts, fasteners, assembly parts and other aircraft parts.

2. Defence Electronics Component Parts: Circuit boards, electronic connectors, wiring assemblies, control units, communication components and power supply modules.

3. Missile and Weapon System Components: Precision machined housings, mechanical parts, mounting parts and assemblies, in accordance with relevant licensing and security regulations.

4. Naval and Marine Components: Marine valves, pumps, piping assemblies, special fittings, corrosion resistant components and mechanical parts for naval platforms.

5. Components for Military Vehicles: Transmissions, suspensions, brakes, fabricated frames, and automotive components.

6. Precision Engineered Parts: CNC machined components, gears, shafts, bearings, fasteners and engineered parts used in military equipment. 

Selection of the appropriate manufacturing category is dependent upon the technical competence of the entrepreneur, machinery, good infrastructure, and meeting the requirements of the customer. It is recommended that MSMEs begin with a specialized component category to build a reputation as suppliers and then diversify into other manufacturing categories.

Investment Required to Start a Defence Component Manufacturing Business

Investment needed for setting up a defence component manufacturing unit depends on the kind of product, production capacity, and machinery and quality control facilities available. A precision engineering unit needs much less investment than an aerospace or defence electronics plant.

The following figures are preliminary planning estimates for different manufacturing models:

The major investment heads include:

• Factory space: Cost of acquiring or renting industrial property and its utilities.
• Machinery: CNC machines, fabricating machinery, assembling machinery and production systems.
• Testing machinery: Inspection and measurement machines and testing systems.
• Labor: Machinists, engineers, technicians and quality control personnel.
• Working capital: Raw materials, stock, wages, costs for maintenance and other expenses.

The above costs are indicative only. Costs will vary depending on specific equipment required, production capability, factory space and working capital requirements.

Machinery, Technology and Infrastructure Requirements

Setting up a defence component manufacturing unit requires machinery suited to the precision, material specifications and production standards of the selected product category. Common equipment includes:

• CNC machine centers: For production of precision metal components, shafts, fastenings and intricate metal parts.
• Laser cutters and fabrication machines: For fabricating metal sheets, cabinets and structure components.
• Metal welding and assembly machines: For assembly and bonding of metal parts.
• PCB assembling and testing machines: For assembling electronic and PCB components.
• Coordinate measuring machines (CMM): For determining dimensions and tolerances of manufactured goods.
• Non-destructive testing equipment: For detecting defectives from inside the component without destroying it.

Also the manufacturers have a need for appropriate industrial space, CAD/CAM software and measuring tools, power supply, etc. The selection of the machinery must conform to the requirements of the defence equipment to be made.

How to Become a Registered Defence Supplier in India

However, being part of the defence supply chain is not just about building a manufacturing plant. MSMEs should be able to find appropriate procurement opportunities and show their ability to manufacture.

The process generally involves the following steps:

1. Find out product opportunities: Use the SRIJAN portal and the lists of indigenisation to find out which products are needed by the defence organisations.
2. Set up production facilities: Set up the production facility that is required to manufacture the identified products.
3. Find out the buyers: Contact the appropriate DPSUs, private defence OEMs, and other procurement organisations.
4. Register as a vendor: Register as a vendor by filling out the appropriate forms and submitting the required documents.
5. Go through the product evaluation process: Send the product samples, technical information, and other required documentation for evaluation wherever required.
6. Take part in the procurement process: Participate in the procurement process where you are eligible to do so.

Vendor registration does not guarantee a defence order. Manufacturers must maintain consistent quality, competitive pricing and delivery capabilities to build lasting supplier relationships.

Where Can MSMEs Find Defence Manufacturing Orders and Business Opportunities?

Procuring buyers and marketing avenues are crucial in creating a sustainable defence component manufacture. There are many venues that MSMEs in India can use to find buyers for their defence components.

• SRIJAN Defence portal: The manufacturer can investigate requirements for indigenisation and find out which components are being sought by defence organizations for indigenization purposes.
