Introduction: Indigenous Steel for INS Taragiri
In 2024, the Steel Authority of India Limited (SAIL) supplied indigenous special grade steel to power INS Taragiri, a Talwar-class frigate of the Indian Navy. This marks the first instance of an Indian naval vessel being constructed using domestically produced special steel tailored for defence applications, reducing reliance on imports for critical materials. The development aligns with India's strategic objective of self-reliance in defence manufacturing under the Make in India initiative, enhancing national security and technological autonomy.

Constitutional and Legal Framework Supporting Indigenous Defence Production
Article 51A of the Constitution imposes a fundamental duty on every citizen to protect the sovereignty and integrity of India, underpinning the policy impetus for indigenous defence production. The Defence Procurement Procedure (DPP) 2020 institutionalizes preference for domestic manufacturing, emphasizing 'Make in India' to reduce import dependency. The Defence Production Policy 2018 further incentivizes development of indigenous technologies and materials, including special steels for naval vessels. Regulatory statutes such as the Indian Telegraph Act, 1885 and the Arms Act, 1959 govern communication infrastructure and defence equipment, ensuring legal compliance in naval shipbuilding.
- Article 51A: Duty to safeguard sovereignty, justifying self-reliance in defence.
- DPP 2020: Prioritizes indigenous content in defence procurement.
- Defence Production Policy 2018: Promotes domestic R&D and manufacturing.
- Indian Telegraph Act, 1885: Regulates naval communications infrastructure.
- Arms Act, 1959: Controls manufacture and possession of defence equipment.
Economic Dimensions of Indigenous Special Steel Production
India's defence budget for 2023-24 is ₹5.94 lakh crore (~$80 billion), with capital expenditure accounting for ₹1.48 lakh crore (~25%), emphasizing indigenous manufacturing. SAIL's annual special steel production capacity stands at 1.5 million tonnes, contributing significantly to defence material needs. The substitution of imported naval-grade steel with indigenous variants for vessels like INS Taragiri is estimated to save $100 million annually, reducing foreign exchange outflow and supply chain vulnerabilities. India's steel production reached 125 million tonnes in 2023, making it the world's second-largest producer, with defence-grade special steel constituting approximately 5% of total demand. The defence manufacturing sector targets a 15% CAGR growth by 2030, reflecting the government's push for self-reliance and economic security.

Key Institutions in Indigenous Defence Steel Production
SAIL leads the production of special steel grades tailored for defence applications, collaborating with the Ministry of Defence (MoD) which oversees procurement and policy implementation. The Defence Research and Development Organisation (DRDO) contributes to materials research for advanced steel alloys. Defence Public Sector Undertakings (DPSUs) integrate these materials into naval shipbuilding, exemplified by INS Taragiri. The Ministry of Steel (MoS) aligns national steel production capabilities with defence requirements, ensuring supply chain coordination.
- SAIL: Produces indigenous special steel for naval vessels.
- MoD: Formulates procurement policies and oversees defence manufacturing.
- DRDO: Develops advanced materials and alloys for defence.
- DPSUs: Manufacture and integrate steel into defence platforms.
- MoS: Coordinates steel production to meet defence demand.
Comparative Analysis: India vs China in Naval Steel Production
China's state-owned Baosteel Group produces specialised naval steel for the People's Liberation Army Navy (PLAN), enabling over 70% indigenous content in warship construction by 2022. India currently achieves an estimated 40-50% indigenous content in naval vessels, reflecting a nascent stage of industrial integration. China's integrated steel supply chain and material R&D infrastructure facilitate higher self-reliance and cost efficiencies. India’s fragmented supply chain for advanced naval-grade steel alloys causes intermittent import dependence, delaying full self-reliance and increasing costs.
| Parameter | India | China |
|---|---|---|
| Key Steel Producer | SAIL | Baosteel Group |
| Indigenous Content in Naval Ships | 40-50% | Over 70% |
| Annual Special Steel Capacity | 1.5 million tonnes | ~10 million tonnes (estimated) |
| Supply Chain Integration | Partial, with import reliance for advanced grades | Highly integrated, minimal imports |
| R&D Support | DRDO and MoS collaboration ongoing | Strong state-backed R&D ecosystem |
Critical Gaps in India's Naval Steel Supply Chain
Despite progress, India lacks a fully integrated supply chain for high-performance naval-grade steel alloys, necessitating intermittent imports of specialized grades. This gap impedes cost reduction, timely production, and complete self-reliance in warship manufacturing. Limited domestic R&D collaboration between steel producers and defence labs constrains innovation in advanced steel metallurgy. Addressing these gaps is essential to meet the projected 15% CAGR growth in defence manufacturing and to reduce strategic vulnerabilities.
- Absence of end-to-end supply chain for advanced naval steel alloys.
- Dependence on imports for certain high-performance steel grades.
- Fragmented R&D efforts limiting innovation in steel metallurgy.
- Impact: Higher costs, delayed production, strategic risks.
Significance and Way Forward
The indigenous production of special steel for INS Taragiri exemplifies India's commitment to defence self-reliance, reducing foreign dependency and enhancing national security. Scaling up SAIL's capacity and fostering stronger R&D linkages with DRDO can improve advanced alloy development. Establishing integrated supply chains and incentivizing private sector participation will accelerate indigenization. Policy coherence between MoD, MoS, and industry is critical to sustain growth and achieve the 15% CAGR defence manufacturing target by 2030.
