Shares of Garden Reach Shipbuilders & Engineers Ltd (GRSE) gained momentum on Friday, rising as much as 5.77% to an intraday high of ₹2,548 on the NSE, after the company announced a strategic partnership with Kalyani Strategic Systems Limited (KSSL), a subsidiary of Bharat Forge Ltd. The companies have signed a Memorandum of Understanding (MoU) to jointly develop and promote indigenous solutions for advanced naval systems and maritime technologies.
In an official announcement on March 5, 2026, GRSE revealed that the agreement aims to co-develop advanced indigenous maritime solutions while strengthening India’s defence manufacturing ecosystem. The collaboration aligns with the government’s vision of Atmanirbharta (self-reliance) in defence production and seeks to expand both companies’ presence in domestic and international markets.
GRSE, a leading warship builder operating under India’s Ministry of Defence, will combine its extensive shipbuilding expertise with KSSL’s technological capabilities as a defence Original Equipment Manufacturer (OEM). Together, the companies intend to develop sophisticated naval platforms and maritime technologies for defence and commercial use.
Under the partnership, the two companies will work across multiple advanced maritime technology segments.
A key focus will be the development of unmanned platforms, including unmanned surface vessels (USVs) and autonomous underwater vehicles (AUVs). These systems are increasingly important in modern naval operations for surveillance, reconnaissance, and autonomous missions.
The collaboration will also extend to mechanical and propulsion systems, where both firms will jointly develop engineering solutions related to ship propulsion and integrated platform management systems.
Despite the wide scope of collaboration, both companies clarified that no specific financial implications have been determined at this stage of the agreement.
The alliance is expected to help both organisations identify and pursue new opportunities in India as well as mutually agreed international markets. By combining GRSE’s shipbuilding expertise with KSSL’s advanced defence technology capabilities, the partnership aims to enhance the operational capabilities of the Indian Navy and the Indian Coast Guard while also promoting Indian-made defence technologies globally.
Established in 1884, Garden Reach Shipbuilders & Engineers Ltd is a “Mini Ratna” Category I defence public sector enterprise and one of India’s premier warship builders. The company has built more than 800 platforms, including 115 warships, the highest number delivered by any Indian shipyard.
GRSE’s portfolio includes frigates, corvettes, patrol vessels, and export warships, with deliveries made to countries such as Mauritius, Seychelles, and Guyana.
Kalyani Strategic Systems Limited is the defence arm of the Kalyani Group, operating under Bharat Forge Ltd. The company specialises in the design, development, and manufacturing of advanced defence systems and platforms, making it a key player in India’s growing defence manufacturing ecosystem.
Through this partnership with GRSE, KSSL aims to further strengthen India’s capabilities in advanced naval technologies, autonomous maritime systems, and indigenous defence production.
