With the launch of DSC A24, the Navy has completed the entire five-vessel project designed to strengthen underwater support operations and improve maritime readiness.

Designed for Advanced Diving Operations
The Diving Support Craft has been designed with a catamaran-hull configuration and has an approximate displacement of 300 to 400 tonnes.
According to the Indian Navy, the design offers several operational advantages, including:
- Superior stability
- Enhanced deck area
- Improved sea-keeping characteristics
These features make the vessels well suited for specialised diving operations in coastal and maritime environments.
The ships have been designed and constructed in accordance with the Naval Rules and Regulations of the Indian Register of Shipping (IRS), ensuring compliance with national naval standards.
Strengthening Operational Capabilities
The induction of the Diving Support Craft fleet is expected to significantly enhance the Indian Navy’s operational capabilities in several specialised areas.
The vessels will support:
- Diving operations
- Underwater inspection
- Salvage assistance
- Coastal operational deployment
The Navy said the new platforms will improve its ability to undertake underwater maintenance, inspection and rescue-related missions while strengthening overall maritime preparedness.

Boost to Aatmanirbhar Bharat
The project also reflects India’s growing emphasis on indigenous defence manufacturing.
According to the Navy, nearly 70 per cent of the main and auxiliary equipment installed onboard the Diving Support Craft has been sourced from indigenous manufacturers.
The DSC Project has therefore emerged as an important contributor to the Government of India’s Aatmanirbhar Bharat and Make in India initiatives in the defence sector, showcasing the increasing capability of domestic shipbuilding and defence industries.
With the successful launch of DSC A24, the Indian Navy has completed the five-vessel Diving Support Craft Project, further strengthening indigenous naval capability and specialised underwater operational support.
