The Indian Navy will commission DSC A20, the first vessel of the indigenously designed and constructed Diving Support Craft (DSC), at Kochi on 16 Dec 2025 under the aegis of Southern Naval Command. The ship will be formally inducted into service in presence of Vice Admiral Sameer Saxena, Flag Officer Commanding-in-Chief, Southern Naval Command. The event will mark the addition of a key operational asset to the Navy’s inventory, enhancing its diving and underwater support capability.
DSC A20 is the lead ship in a series of five Diving Support Craft being built by M/s Titagarh Rail Systems Limited (TRSL), Kolkata. Purpose-built for a wide spectrum of diving and underwater missions in coastal waters, the vessel is equipped with advanced, state-of-the-art diving systems that meet the highest standards of safety and operational efficiency.
Featuring a catamaran hull form, the ship offers superior stability, enhanced deck area, and improved seakeeping characteristics, and has a displacement of approximately 390 tons. Designed and built in accordance with the Naval Rules and Regulations of the Indian Register of Shipping (IRS), DSC A20 underwent extensive hydrodynamic analysis and model testing at the Naval Science and Technological Laboratory (NSTL), Visakhapatnam, ensuring optimal performance and reliability.
The commissioning of DSC A20 marks a milestone in India’s pursuit of Aatmanirbharta and exemplifies success of ‘Make in India’ initiative in the maritime domain. The platform represents seamless collaboration between the Indian Navy, the indigenous shipbuilding industry, and national research organisations in delivering specialised, technologically advanced vessels.
With its induction, the Indian Navy’s capability in diving support, underwater inspection, salvage assistance, and coastal operational deployment will be substantially strengthened. DSC A20 will be based at Kochi and operate under Southern Naval Command.
