The Garden Reach Shipbuilders & Engineers (GRSE), Kolkata, delivered AGRAY, the fourth Anti-Submarine Warfare (ASW) Shallow Water Craft (SWC) for the Indian Navy in early 2024 (PIB, 2024). This 50-meter, 350-tonne vessel is equipped with advanced indigenous sonar systems capable of submarine detection up to 15 km, operational speed of 25 knots, and endurance of 7 days at sea (DRDO, 2023). The delivery underscores India’s growing self-reliance in naval defence production under the Atmanirbhar Bharat and Make in India initiatives, enhancing maritime security in the country’s vulnerable littoral zones.

Legal and Constitutional Framework Governing Naval Procurement
Naval procurement, including the AGRAY project, operates under the Defence Procurement Procedure (DPP) 2020, which emphasizes indigenous content and transparency. Article 246 and Entry 2 of the Union List empower Parliament to legislate on naval defence. The Indian Navy Act, 1957 (Act No. 62 of 1957) provides the statutory framework for naval operations, while the Defence of India Act, 1962 supplements wartime provisions. Supreme Court rulings, such as Union of India v. R. Gandhi (2010), have reinforced transparency and accountability in defence procurement processes.
- DPP 2020 mandates at least 50% indigenous content for capital acquisitions.
- Parliament’s exclusive power under Union List Entry 2 covers naval defence policy and procurement.
- DGQA ensures quality assurance and certification of naval vessels.
Economic Dimensions of the AGRAY Project
The AGRAY contract, valued at approximately ₹1,200 crore, is part of the Defence Budget 2023-24 allocation of ₹5.25 lakh crore, with 25% earmarked for capital acquisitions emphasizing indigenous manufacturing (MoD report, 2023). The project supports the Indian shipbuilding industry projected to grow at a CAGR of 7.5% till 2030 (IBEF, 2023). Import substitution through AGRAY saves an estimated $150 million per vessel in foreign exchange outflow. The project also generates direct and indirect employment for over 1,000 skilled workers across GRSE and ancillary industries.
- Defence capital acquisition budget prioritizes Make in India projects.
- Shipbuilding sector growth driven by naval and commercial vessel demand.
- Employment boost in skilled manufacturing and technology sectors.
Key Institutions Involved in AGRAY Development and Deployment
The AGRAY-class project is a collaborative effort among multiple institutions. GRSE is the principal shipbuilder responsible for construction and integration. The Indian Navy operates and maintains the vessels. The Ministry of Defence (MoD) oversees policy and procurement. DRDO provides technology support for sonar and ASW systems. The Directorate General of Quality Assurance (DGQA) certifies quality standards. The Navy Design Bureau handles vessel design and customization to operational requirements.
- GRSE’s expertise in ASW shallow water craft construction since early 2010s.
- DRDO’s sonar technology enables 15 km submarine detection range.
- MoD’s procurement policies align with strategic autonomy goals.
Technical Specifications and Operational Capabilities of AGRAY
The AGRAY-class SWC measures approximately 50 meters in length with a displacement of 350 tonnes. It features advanced sonar capable of detecting submarines up to 15 km, an operational speed of 25 knots, and endurance of 7 days at sea (Indian Navy specifications, 2023). Indigenous content exceeds 70%, reflecting Make in India targets. These vessels are optimized for shallow water ASW operations, addressing 60% of India’s littoral zones vulnerable to submarine incursions (Indian Navy Maritime Doctrine, 2022).
| Parameter | AGRAY (India) | Type 056 Corvette (China) |
|---|---|---|
| Length | ~50 meters | ~90 meters |
| Displacement | ~350 tonnes | ~1,500 tonnes |
| Sonar Range | 15 km (indigenous) | ~12-15 km (mixed indigenous/imported) |
| Indigenous Content | >70% | ~50-60% |
| Operational Role | Shallow water ASW | Multi-role littoral ASW and patrol |
| Fleet Size | 4 vessels (AGRAY class) | 20+ vessels (Type 056) |
| Design Philosophy | Modular, flexible for upgrades | Standardized, less modular |
Strategic and Operational Gaps in India’s ASW Shallow Water Fleet
Despite the qualitative leap represented by AGRAY, India’s ASW shallow water fleet remains numerically limited relative to its 7,516 km coastline and increasing submarine threats. Integration of AI-based sonar and unmanned underwater vehicles (UUVs) is nascent, whereas China and the US have rapidly advanced autonomous ASW capabilities. This limits India’s ability to maintain persistent underwater domain awareness in littoral waters.
- Limited fleet size constrains area coverage and rotational deployment.
- Emerging technologies like AI sonar and UUVs are underdeveloped domestically.
- China’s larger fleet and advanced autonomous systems provide strategic edge in littoral ASW.
Significance and Way Forward
- AGRAY’s delivery strengthens India’s indigenous naval manufacturing and operational self-reliance.
- Scaling up production and accelerating integration of AI and unmanned systems is essential to close capability gaps.
- Enhancing inter-agency coordination between MoD, DRDO, and Navy Design Bureau will improve technology assimilation.
- Expanding indigenous content beyond 70% will reduce import dependence and bolster defence exports.
- Focused investments in shipbuilding infrastructure and skilled workforce development will sustain long-term maritime security.
- AGRAY is the first ASW shallow water craft built by GRSE for the Indian Navy.
- It has an operational speed of 25 knots and endurance of 7 days at sea.
- AGRAY’s indigenous content exceeds 70% as per MoD reports.
Which of the above statements is/are correct?
- DPP 2020 mandates at least 50% indigenous content for capital acquisitions.
- It is a statutory Act passed by Parliament.
- DPP 2020 governs quality assurance through DGQA certification.
Which of the above statements is/are correct?
What is the primary operational role of the AGRAY-class vessels?
AGRAY-class vessels are designed for Anti-Submarine Warfare (ASW) operations in shallow coastal waters, targeting submarine threats within India’s littoral zones. Their sonar systems enable detection of submarines up to 15 km, enhancing underwater domain awareness.
Which institution is responsible for building the AGRAY-class ships?
The Garden Reach Shipbuilders & Engineers (GRSE), Kolkata, is the principal shipbuilder responsible for constructing the AGRAY-class ASW shallow water crafts for the Indian Navy.
What legal framework governs the procurement of naval vessels like AGRAY?
The Defence Procurement Procedure (DPP) 2020 governs acquisition, supported by constitutional provisions under Article 246 and Entry 2 of the Union List, and statutory laws such as the Indian Navy Act, 1957.
How does AGRAY contribute to India’s economic goals in defence?
AGRAY’s construction promotes indigenous manufacturing, reduces foreign exchange outflow by an estimated $150 million per vessel, and generates employment for over 1,000 skilled workers, aligning with the Make in India and Atmanirbhar Bharat initiatives.
What are the critical capability gaps in India’s ASW shallow water fleet?
India’s ASW shallow water fleet is numerically limited and lacks advanced integration of AI-based sonar and unmanned underwater vehicles, areas where China and the US have made significant progress.
