Key Details
India’s indigenous naval shipbuilding programme is developing complementary maritime capabilities - from blue-water combat and seabed mapping to coastal anti-submarine warfare - while expanding domestic defence manufacturing.
Capability | Recent Development | Strategic Significance |
|---|---|---|
Blue-water combat | INS Mahendragiri commissioned as the sixth Project 17A stealth frigate; INS Dunagiri inducted earlier | Strengthens long-range maritime operations and fleet air defence |
Maritime domain awareness | INS Sanshodhak completes the Sandhayak-class survey vessel programme | Improves hydrographic surveying, navigation safety and EEZ management |
Coastal security | INS Agray inducted under the Arnala-class ASW programme | Enhances anti-submarine capability in shallow coastal waters |
Indigenous shipbuilding | Project 17A frigates contain about 75% indigenous content; survey vessels exceed 80% | Advances defence self-reliance and domestic industrial capability |
Defence manufacturing | Most naval platforms are now designed by the Indian Navy and constructed in Indian shipyards | Strengthens the domestic defence industrial ecosystem and MSME participation |
Indigenous Shipbuilding Enters a New Phase
India is growing its ability to design, build and induct advanced naval platforms domestically. Recent inductions - including the stealth frigates INS Mahendragiri and INS Dunagiri, the hydrographic survey vessel INS Sanshodhak, and the anti-submarine warfare vessel INS Agray - demonstrate how indigenous shipbuilding is supporting a broader expansion of maritime capability while reducing dependence on imported defence platforms.
Rather than representing isolated additions to the fleet, these vessels perform complementary roles across blue-water operations, coastal defence and maritime domain awareness.
Building Complementary Maritime Capabilities
The inducted platforms strengthen different aspects of India’s maritime posture. Project 17A frigates enhance long-range combat capability and fleet protection; the Sandhayak-class expands hydrographic surveying, nautical charting and seabed mapping; while the Arnala-class strengthens anti-submarine operations in shallow coastal waters.
Together, they illustrate a shift towards building a balanced naval force capable of protecting sea lanes, supporting offshore infrastructure, improving navigation safety and strengthening surveillance across India’s maritime interests.
Defence Manufacturing and Maritime Strategy Become Increasingly Integrated
The role of indigenous defence production in India’s maritime strategy is also becoming significant. Designed largely by the Indian Navy’s Warship Design Bureau and built by Indian shipyards such as Mazagon Dock Shipbuilders Limited and Garden Reach Shipbuilders & Engineers, these platforms incorporate high levels of domestic content and support a wider ecosystem of suppliers and MSMEs.
The emphasis on indigenous design, serial production and domestic manufacturing reflects a broader effort to align operational capability with the objectives of Aatmanirbhar Bharat and strengthen India’s long-term defence-industrial base.
What is Project 17A?
Project 17A is the Indian Navy’s programme for constructing next-generation stealth guided-missile frigates with improved survivability, automation, network-centric warfare capability and higher indigenous content. The project builds on the earlier Shivalik-class frigates while incorporating advanced design and construction technologies.
Policy Relevance
The backgrounder illustrates how indigenous shipbuilding is becoming a central pillar of India’s maritime security strategy, reducing dependence on imported naval platforms.
Building complementary capabilities across combat operations, hydrographic surveying and coastal anti-submarine warfare strengthens India’s ability to protect its maritime interests across the Indian Ocean Region.
High indigenous content and domestic construction reinforce the objectives of Aatmanirbhar Bharat by expanding defence manufacturing capability, technology development and MSME participation.
Continued investment in indigenous naval design can strengthen India’s long-term defence preparedness while creating opportunities for defence exports and industrial innovation.
The integration of naval capability with hydrographic surveying and maritime domain awareness highlights the growing convergence between national security, Blue Economy development and management of India’s Exclusive Economic Zone.
Relevant Question for Policy Stakeholders: As India expands indigenous naval shipbuilding, how can defence procurement, industrial policy and maritime strategy be better aligned to sustain continuous domestic production, strengthen critical technologies and enhance long-term maritime capability?
