India needs a new generation of naval destroyers

Sayan Chatterjee

The Indian Ocean is becoming an increasingly important arena of strategic competition. From protecting vital shipping lanes and securing energy supplies to tracking military movements and safeguarding maritime interests, India’s naval responsibilities are expanding. The reported in-principle clearance for Indian Navy’s next-generation destroyer programme, Project 18A, therefore marks a significant step in the country’s long-term maritime planning. The Defence Acquisition Council (DAC), chaired by Defence Minister Rajnath Singh, reportedly gave the programme an initial push on October 26, placing it under the naval platforms category. The proposed stealth guided-missile destroyers, to be designed by the Navy’s Warship Design Bureau, are expected to be larger and more capable than existing frontline destroyers.

Reports have put the potential project cost at more than 75,000 crore, although the final configuration, procurement arrangements, and delivery schedule remain subject to subsequent decisions. The significance of Project 18A extends beyond the induction of another class of warships. Modern naval power increasingly depends on a combination of firepower, surveillance, sensor integration, communications and the ability to respond to threats across multiple domains. A destroyer is not merely a heavily armed ship; it is also a platform for detecting threats, coordinating operations and protecting other naval assets. For India, these capabilities matter in an Indian Ocean region that carries substantial global trade and energy traffic. The Navy must be prepared for conventional military challenges as well as evolving threats involving long-range missiles, submarines, unmanned systems and electronic warfare. The proposed destroyers also represent an opportunity to deepen India’s indigenous warship-design and construction capabilities. The Warship Design Bureau’s role places domestic design expertise at the centre of the programme. If supported by a strong indigenous supply chain, the project could create opportunities for Indian shipyards, defence manufacturers and technology companies working on sensors, communications, weapons and other complex naval systems. However, self-reliance must mean more than assembling a ship within the country.

Critical technologies must be developed, tested, maintained and upgraded with a growing degree of domestic control. Dependence on external suppliers for essential components can create vulnerabilities during geopolitical crises, export restrictions or supply-chain disruptions. A credible indigenous ecosystem would give India greater freedom to sustain and modernise its fleet over the long term. The financial and industrial demands will be considerable. A programme reportedly worth upwards of 75,000 crore must be judged not only by the capabilities promised but also by its affordability, execution and long-term maintenance requirements. Warship construction is complex, and delays in design, equipment integration or supply chains can affect delivery schedules.

Competitive procurement and a clear division of industrial responsibilities will be important in securing value for public expenditure. The reported timeline also underlines the need for a long-term perspective. If deliveries begin five to ten years after the contract is signed, the Navy must plan for the threats these ships will encounter when they enter service, rather than simply reproduce today’s capabilities. Their design must account for technological advances and allow room for upgrades throughout their operational lives.

Project 18A should therefore be viewed as an investment in India’s future maritime posture, not merely as a shipbuilding programme. Its success will depend on whether the Navy can combine advanced design, indigenous technology, disciplined procurement, and timely execution. India’s maritime ambitions demand a fleet that can deter threats, protect national interests and operate confidently across a vast region. The next-generation destroyers could become an important part of that effort. But their true strategic value will ultimately lie not in their size or cost, but in the capability they deliver, the industrial strength they create and the freedom of action they give India at sea.
