India’s naval modernisation efforts are experiencing a surge in international competition. South Korea’s HD Hyundai Group has proposed building a massive $4 billion (roughly ₹40,000 crore) greenfield shipyard in Thoothukudi, Tamil Nadu.
This move comes shortly after Japan presented an unprecedented offer to share the technology and co-produce its advanced Mogami-class stealth frigates in India.
These competing proposals highlight a growing rivalry among global shipbuilding leaders eager to participate in India’s future warship projects under the 'Make in India' initiative.
HD Hyundai aims to be the primary anchor partner for this new facility, which is planned to be an enormous industrial centre catering to both commercial and naval shipbuilding needs.
Open-source reports indicate the shipyard could feature an immense production capacity of up to 4 million gross tonnage (GT), supported by a sprawling 3,000-acre vendor cluster that may include steel giant POSCO.
The strategic coastal location of Thoothukudi offers excellent maritime access and logistical benefits, making it highly suitable for efficient vessel construction, outfitting, and testing.
While commercial vessels will be built here, a primary goal is to meet the Indian Navy’s demand for future surface warships, signalling HD Hyundai’s serious commitment to India’s defence manufacturing sector.
To strengthen its position, HD Hyundai Heavy Industries (HD HHI) is offering the HDF-6000 (also known as HD6000) frigate to the Indian Navy.
This 6,500-ton warship, which was recently showcased at the MADEX 2025 exhibition, is built specifically for the export market.
Often referred to as a "mini-destroyer" because of its heavy firepower and long-endurance blue-water capabilities, the HDF-6000 is based on the highly successful hull of South Korea’s KDX-II destroyers.
It combines this proven foundation with modern stealth features, a reduced radar cross-section, and the latest combat technologies.
The heavily armed HDF-6000 is fully equipped for modern naval combat. It features a 76mm main gun, a large 48-cell Vertical Launch System (VLS) that can fire surface-to-air missiles and handle ballistic missile defence tasks, and eight launchers for anti-ship missiles.
Additionally, it comes with advanced close-in weapon systems (CIWS) and anti-drone defences to protect against modern threats like unmanned aerial swarms. Measuring about 139 metres long, this 6,500-ton vessel effectively bridges the gap between standard frigates and larger destroyers.
The timing of South Korea's proposal is particularly notable.
Japan recently made a historic offer to transfer the complete design of its highly automated Mogami-class stealth frigate—a high-tech vessel requiring a crew of only about 90 sailors—for local production in India.
While Japan's offer focuses heavily on sharing advanced warship designs and enabling co-production, South Korea is taking a broader approach.
By committing to a $4 billion shipyard, HD Hyundai is promising to build massive, long-term industrial capacity within India, opening doors for continuous production and future exports.
These competing offers align perfectly with New Delhi's goal to transform India into one of the world's top five shipbuilding nations by 2047.
By leveraging foreign investments that bring in advanced technology, local manufacturing, and a dedicated supply chain, India aims to create a powerful domestic industry capable of building complex warships independently.
If the Thoothukudi shipyard project moves forward, it will become a crucial pillar of this vision, fulfilling domestic naval needs while establishing India as a hub for maritime exports.
From a broader strategic perspective, these parallel offers from Tokyo and Seoul highlight India’s vital role in Indo-Pacific security. Both nations see India as an essential partner in countering the rapid expansion of Chinese naval activity in the Indian Ocean.
For India, this rivalry presents a golden opportunity to avoid depending on a single supplier. Instead, New Delhi can carefully select the best advanced technologies to rapidly boost its indigenous defence manufacturing capabilities while securing the maritime domain.
