HSL and Cyient DLM Sign MoU to Manufacture Advanced Ship Electronics in India.
Hindustan Shipyard-Cyient DLM MoU signing ceremony.
Hindustan Shipyard Limited (HSL) and Cyient DLM Naval Electronics MoU: India’s efforts to strengthen its domestic defence manufacturing industry are moving beyond the construction of warships and submarines to the sophisticated electronic systems that make modern naval vessels operational. A new partnership between Hindustan Shipyard Limited (HSL) and Cyient DLM is aimed at advancing this objective by developing and manufacturing a range of naval electronics in India.
On 14 November, the two companies signed a memorandum of understanding (MoU) to establish a joint venture focused on designing and manufacturing electronic equipment for ships. The proposed collaboration is intended to reduce India’s dependence on overseas suppliers while strengthening the domestic industrial base supporting the Indian Navy and other maritime organisations.
The agreement is significant because building a modern naval vessel involves considerably more than constructing its hull, installing engines and fitting weapons. Ships also require sophisticated navigation systems, radar, communications equipment, automated controls and safety technologies. Many of these systems are technologically complex and require specialised expertise to design, manufacture and maintain.
Through the proposed joint venture, HSL and Cyient DLM want to develop more of these capabilities within India.
What will the HSL-Cyient DLM joint venture manufacture?
The proposed partnership covers a broad range of electronic systems used in modern naval and maritime vessels.
These include navigation systems, solid-state radars, Electronic Chart Display and Information Systems (ECDIS), autopilots, Global Maritime Distress and Safety System (GMDSS) equipment, Fleet Broadband communications systems and voyage data recorders.
The companies have also identified weather-reporting systems and helicopter landing aids as potential areas of development.
Each of these technologies serves a different purpose, but together they help a vessel navigate safely, communicate effectively and operate under different maritime conditions.
For example, radar systems help ship crews detect and track surrounding vessels and other objects. Navigation equipment provides information about a ship’s position and surroundings, while electronic chart systems allow crews to plan and monitor routes using digital maritime maps.
Autopilots can assist with maintaining a vessel’s direction, reducing the need for continuous manual steering. Meanwhile, communications equipment enables ships to exchange information with other vessels and shore-based authorities.
Safety systems are equally important. GMDSS equipment supports maritime distress communications, while voyage data recorders preserve information about a vessel’s operations. These records can be useful when investigating incidents or understanding a ship’s performance.
The proposed product range therefore extends across several essential areas of maritime operations rather than concentrating on a single category of equipment.
Why does India need indigenous naval electronics?
India has made considerable progress in developing its domestic warship-building capabilities. Public-sector shipyards and private companies are increasingly involved in constructing vessels for the Indian Navy, Coast Guard and other maritime agencies.
However, a ship built in India does not necessarily contain only Indian-made equipment.
Modern naval vessels depend on specialised electronic systems, sensors, communication technologies and navigation equipment. Some of these components have traditionally been sourced from international manufacturers.
This creates a potential weakness in the domestic defence supply chain.
Dependence on foreign suppliers can affect equipment delivery schedules, spare-parts availability, maintenance arrangements and the ability to upgrade systems. International supply disruptions or restrictions can also complicate procurement and long-term support.
Developing these systems domestically could help address such challenges.
A stronger Indian manufacturing base would give shipyards and naval authorities additional procurement options. It could also make it easier to obtain replacement components, arrange repairs and undertake upgrades without relying entirely on overseas manufacturers.
However, domestic production alone does not guarantee independence. Indian-made systems must also meet demanding technical, operational and reliability standards before they can be used aboard naval vessels.
This is particularly important because electronic equipment installed on ships must function reliably in challenging maritime environments, where vibration, moisture, temperature variations and prolonged operations can affect performance.

How will the proposed partnership work?
Under the MoU, HSL and Cyient DLM are expected to identify priority electronic systems and establish teams to undertake their design and development.
The process will involve developing equipment, testing prototypes and obtaining the necessary naval and classification approvals before the systems can be installed on operational vessels.
These approvals are an important part of the process. Naval equipment cannot be introduced simply because it has been manufactured successfully. It must demonstrate that it can perform consistently under the conditions in which it will be used.
The companies are reportedly considering 18 Next Generation Fast Patrol Vessels (NGFPVs) as initial platforms for the proposed equipment.
This could provide an opportunity to introduce domestically developed electronics into a vessel-building programme while establishing a foundation for future production and deployment.
However, the companies have not publicly disclosed the proposed joint venture’s investment, manufacturing capacity, first delivery schedule or detailed arrangements for selecting the initial systems.
These details will be important in assessing the scale and commercial significance of the partnership.
Why are the 18 Next Generation Fast Patrol Vessels important?
The proposed collaboration is closely linked to India’s wider efforts to expand domestic maritime manufacturing.
In January, Hindustan Shipyard emerged as the lowest bidder in a competition to build 18 Next Generation Fast Patrol Vessels for the Indian Coast Guard. The project was estimated to be worth approximately ₹3,000 crore. A subsequent report indicated that HSL had secured the contract.
The vessels are intended to support a range of maritime security responsibilities, including coastal and exclusive economic zone patrols, fisheries protection, anti-smuggling operations, search and rescue missions and the interception of suspicious vessels.
These duties require vessels to remain operationally effective across different sea conditions and geographical areas.
Reliable navigation, radar and communications systems are therefore essential.
The proposed electronics partnership could help create a domestic supply chain for some of the equipment required by these vessels. It could also offer a practical opportunity to test and qualify Indian-developed systems in a real shipbuilding programme.
If successful, the experience gained could support the development of similar equipment for other naval and maritime platforms.
What does Cyient DLM bring to the partnership?
The collaboration brings together two companies with different but potentially complementary capabilities.
Hindustan Shipyard is a defence public sector undertaking with experience in shipbuilding and maritime engineering. Its involvement provides a direct connection to vessel construction requirements and the operational needs of maritime customers.
Cyient DLM brings specialist electronics design and manufacturing capabilities to the proposed venture.
The combination could help bridge the gap between designing electronic equipment and integrating it into actual naval platforms.
Cyient DLM chief executive Rajendra Velagapudi said the partnership would support the development of India’s technology and manufacturing capabilities in the maritime and defence sectors.
HSL has also highlighted the potential to increase the use of indigenous technologies in its vessels.
Such cooperation reflects a broader industrial approach in which public-sector defence manufacturers work with private companies to develop specialised products and technologies.
Rather than depending entirely on imported equipment or attempting to develop every capability within a single organisation, partnerships can bring together expertise from different parts of the industrial ecosystem.

India’s defence indigenisation strategy
The HSL-Cyient DLM agreement is consistent with the government’s wider objective of strengthening India’s domestic defence manufacturing industry.
Defence indigenisation is not limited to manufacturing complete platforms such as aircraft, submarines, warships or armoured vehicles. It also involves developing the components, electronics, sensors, software and supporting technologies required to operate them.
Building these capabilities domestically can create opportunities for Indian manufacturers, engineering companies and specialist technology suppliers.
It can also help retain more manufacturing activity and technical expertise within the country.
For the maritime sector, the benefits could extend beyond the Indian Navy. The Coast Guard and other commercial and government maritime operators may also require navigation, communications and safety equipment.
A successful domestic electronics programme could therefore create opportunities across a wider market.
Nevertheless, the transition from an MoU to a functioning manufacturing operation will require considerable technical and commercial work.
The immediate challenge for HSL and Cyient DLM will be turning the agreement into a practical development and manufacturing programme.
The companies must identify which systems should be developed first, establish technical teams, build prototypes and complete the required testing and certification procedures.
They will also need to demonstrate that their products can compete with established international equipment in terms of performance, reliability and long-term maintenance.
The proposed use of the 18 NGFPVs as initial platforms could provide an important starting point, although the precise equipment selection and installation schedule have not yet been announced.
Ultimately, the success of the partnership will not be measured simply by the signing of an MoU or the establishment of a joint venture. It will depend on whether the companies can deliver operationally reliable equipment within the required timelines and support it throughout the vessels’ service lives.
For India, the broader objective is straightforward but strategically important: building more of the technology that makes its ships work.
The country has been expanding its ability to construct warships and other maritime platforms. Developing indigenous radar, navigation, communications and safety systems would take that effort a step further.
If the proposed venture delivers on its objectives, it could help India move towards a more complete domestic shipbuilding ecosystem, in which the country manufactures not only the vessels but also a greater share of the advanced technology installed aboard them.
