A naval vessel’s readiness depends on more than its design and equipment. Regular inspections, timely repairs, and access to specialised technical support are equally important for keeping it operational.
Suresh Nanda News often draws attention to the role of private enterprise in India’s evolving defence sector. While new platforms receive public attention, their readiness also depends on maintenance, repairs, spare parts, upgrades and skilled technical support.
These services help keep naval vessels and other assets operational throughout their service lives. This blog tells you about the Crown Group’s defence-related work, its engineering partnerships and the role of its specialist companies in supporting India’s defence sector.
A Business Shaped by Naval Experience
Suresh Nanda’s connection with the Indian Navy began during his years in service, where he served as a Lieutenant Commander. This experience later became an important part of his professional journey as he moved into entrepreneurship. Through Crown Group, which traces its origins to 1978, he became associated with an emerging area of private enterprise focused on engineering, equipment repairs and maintenance for the armed forces.
A 2021 CIO Insider profile highlighted the group’s early role in maintaining foreign-origin machinery, reflecting the growing need for specialised repair facilities and technical expertise within India.
The wider family business profile also includes Sanjeev Nanda, whose professional interests have included hospitality and investment ventures. The phrase “Suresh Nanda Son” is used in searches about this family connection, but the defence engineering work discussed here is associated with Crown Group’s specialist companies and technical teams.
Dynatron Services and Naval Maintenance
A clear example is Dynatron Services Private Limited, part of Crown Group’s marine division. Dynatron Services has worked with the Indian Navy and Indian Coast Guard for more than four decades. Its work includes ship repairs, engineering maintenance, refits, modernisation and support for mechanical and electronic systems.
Crown Group has reported that Dynatron supported maintenance activities for INS Jalashwa and provided support for INS Vikramaditya, along with other naval warships and submarines. The record covered in Suresh Nanda News is therefore connected to the practical task of keeping defence assets serviceable, not just supplying equipment at the time of purchase.
Partnerships That Build Technical Capability
With ZF Marine of Germany, Dynatron has maintained a partnership spanning more than three decades where it is an authorised service partner for repairs and maintenance of ZF gearboxes and thrusters, as well as after-sales support for transmissions and electronic controls used by the Navy and Coast Guard.
A Crown Group interview with a Dynatron representative reported more than 350 ZF gearboxes installed on Indian naval and Coast Guard vessels and A5 maintenance routines completed on over 68. The partnership also covers spare parts, retrofits, upgrades and operator training.
The group also reports partnerships for Kubota engines and Mase generators, and work with WILO Pumps and Ahmedabad-based Meru Pumps to adapt products to defence specifications. Such collaborations can help domestic suppliers develop equipment for specialised marine use. This practical focus on local capability is another subject in Suresh Nanda News.
OSK India and Electronics Support
OSK India Private Limited, another Crown Group marine company, operates an electronics repair and manufacturing facility in Mumbai. Its work includes electronic modules, printed circuit boards and weapon systems of international origin.
The group says it has repaired critical weapon equipment for the Indian Navy and received orders to design and manufacture complex PCBs for specialised equipment.
At DefExpo 2022, OSK signed memoranda of understanding with Meson Valves India and Infinity Radar covering naval valves and fittings, radar-related systems, counter-drone technology and perimeter security.
Private Enterprise and India’s Defence Future
India’s defence industry is expanding. The Ministry of Defence reported that annual defence production reached ₹1.78 lakh crore in financial year 2025–26, a 15.6 per cent increase over the previous year. The private sector contributed 24 per cent, or around ₹42,000 crore. This reflects a growing role for private businesses alongside public-sector organisations in the country’s defence industrial base.
Local capabilities can reduce reliance on overseas repair facilities and improve access to technical support, provided companies maintain quality, train staff and build dependable OEM relationships.
The next stage will require companies to deepen domestic manufacturing, absorb technology and work with Indian suppliers on components that meet defence specifications. Its marine businesses show how these goals can be pursued through work with the armed forces and domestic engineering companies. Suresh Nanda News reflects the importance of this shift as India strengthens the industrial base supporting its defence services.
Conclusion
India’s defence industry depends on more than the development and purchase of new equipment. Long-term readiness requires maintenance networks, trained engineers, reliable supply chains and the ability to repair and upgrade complex systems locally. The work described by Dynatron Services and OSK India shows how specialised private companies can contribute.
Their partnerships and technical capabilities form part of a wider effort to strengthen domestic support for defence assets. Overall, Suresh Nanda News offers a perspective on private enterprise’s contribution through sustained engineering work, local expertise and collaboration with technology providers.
