The Indian Navy commissioned the sixth Nilgiri-class frigate in 2024, marking a significant milestone in its fleet modernization program. Constructed indigenously by Mazagon Dock Shipbuilders Limited (MDL), this frigate enhances the Navy’s surface combatant strength and operational capabilities. The Nilgiri-class, equipped with advanced stealth features and BrahMos supersonic cruise missiles, reflects India’s strategic emphasis on indigenous defense production and maritime security in the Indo-Pacific region.

This induction elevates the fleet strength of Nilgiri-class frigates to six, contributing to the Indian Navy’s target of expanding its warship count to 160 by 2030. The project aligns with the Ministry of Defence’s capital budget allocation of approximately ₹45,000 crore for indigenous warship construction under the Make in India initiative, supporting both strategic autonomy and economic growth.

Legal and Constitutional Framework Governing Naval Induction

Article 246(1) of the Constitution grants Parliament exclusive power to legislate on defense, encompassing naval force composition and procurement. The Indian Navy operates under the Navy Act, 1957, with Section 3 defining the naval forces’ composition and command hierarchy. The Defence Procurement Procedure (DPP) 2020 governs acquisition, emphasizing indigenous development and timely delivery of naval assets like the Nilgiri-class frigates.

• Parliament’s legislative competence under Article 246(1) ensures centralized policy formulation for defense acquisition.
• Navy Act, 1957, legally establishes the Indian Navy’s structure and operational command.
• DPP 2020 prioritizes Make in India, indigenous content, and procedural efficiency in defense procurement.

Economic Impact of Nilgiri-class Frigate Construction

The Nilgiri-class frigate program forms a critical part of the ₹45,000 crore indigenous warship construction budget in Union Budget 2023-24. MDL’s shipbuilding activities have generated employment for over 10,000 skilled workers, directly supporting the Make in India initiative. The project contributes to the domestic defense manufacturing sector’s goal of reaching $25 billion by 2025, as per Department for Promotion of Industry and Internal Trade (DPIIT) data.

• Indigenous construction reduces import dependence and enhances defense industrial base.
• Employment generation in shipyards like MDL boosts regional economies and skill development.
• Naval modernization stimulates ancillary industries such as electronics, metallurgy, and missile manufacturing.

Key Institutions in Nilgiri-class Frigate Development

The Indian Navy leads operational deployment and fleet management of the Nilgiri-class frigates. MDL, a public sector shipyard, is responsible for construction, leveraging advanced shipbuilding technologies. The Ministry of Defence formulates policies, allocates budgets, and oversees procurement. The Defence Research and Development Organisation (DRDO) provides critical technological inputs, while the Directorate General of Naval Design (DGND) handles vessel design and development.

• Indian Navy: Operational command and strategic deployment.
• MDL: Indigenous construction and project execution.
• MoD: Policy, budget, and procurement oversight.
• DRDO: Technology development and integration.
• DGND: Naval vessel design and innovation.

Technical and Strategic Features of Nilgiri-class Frigates

The Nilgiri-class frigates displace approximately 6,670 tonnes and incorporate stealth technology to reduce radar cross-section. They are equipped with BrahMos supersonic cruise missiles, enhancing strike capabilities. These frigates represent a qualitative leap in India’s surface combatants, enabling multi-dimensional warfare including anti-air, anti-surface, and anti-submarine operations.

• Displacement: ~6,670 tonnes, enabling enhanced endurance and payload.
• Stealth features: Reduced radar and infrared signatures for survivability.
• Armament: BrahMos missiles, advanced sensors, and electronic warfare suites.
• Multi-role capability: Surface, sub-surface, and air threat engagement.

Challenges in Naval Shipbuilding and Procurement

Despite progress, Indian naval shipbuilding faces delays due to bureaucratic procedures and limited private sector involvement. Integration of cutting-edge technologies is hindered by coordination gaps between DRDO, shipyards, and vendors. In contrast, China’s centralized state-owned enterprises enable faster production and technology assimilation, allowing rapid fleet expansion.

• Bureaucratic delays impact timely delivery and operational readiness.
• Limited private sector participation restricts innovation and capacity.
• Technology integration challenges reduce efficiency and increase costs.

Significance and Way Forward

The sixth Nilgiri-class frigate’s induction strengthens India’s maritime deterrence amid rising Indo-Pacific competition. It exemplifies successful indigenous warship construction aligned with strategic autonomy goals. To sustain momentum, reforms must focus on streamlining procurement, enhancing private sector participation, and accelerating technology integration. This will ensure India’s naval capabilities keep pace with evolving regional security dynamics.

• Enhance procurement efficiency under DPP 2020 to reduce delays.
• Encourage private sector and MSME involvement in naval manufacturing.
• Strengthen collaboration between DRDO, DGND, and shipyards for tech integration.
• Expand indigenous content beyond 70% to achieve self-reliance.
