DSC A 23, the fourth ship of five Diving Support Craft (DSC) project was launched on 19 Apr 2026 at Titagarh, Kolkata (WB) by Mrs Deepa Sivakumar, in the presence of Vice Admiral B Sivakumar, Chief of Materiel. The event was conducted with full naval traditions and ceremonial splendour, in presence of senior officials from Indian Navy and M/s Titagarh Rail Systems Limited (TRSL).
The construction of Diving Support Craft is being undertaken by M/s TRSL, Kolkata. Featuring a 30 m long catamaran-hull form and an approximate displacement of 380 tons, these ships offer superior stability, enhanced deck area and improved sea-keeping characteristics, which makes them suitable for undertaking Diving operations in coastal waters and harbours.
Designed and built in accordance with the Naval Rules and Regulations of the Indian Register of Shipping (IRS), the project underwent extensive Model Testing and Hydrodynamic Analysis at the Naval Science and Technological Laboratory (NSTL), Visakhapatnam.
With induction of these ships, the Indian Navy’s capabilities in Diving Support, Underwater Inspection, Salvage Assistance and Coastal Operational Deployment will be augmented. With 70% of main and auxiliary equipment sourced from indigenous manufacturers, Diving Support Craft are proud flag bearers of Aatmanirbhar Bharat and Make in India initiatives of Government of India (GoI) and Ministry of Defence (MoD).
