India DSC A23: India has taken one more strong step in making its own defence equipment at home. On April 19, 2026, the fourth Diving Support Craft under this project, DSC A23, was launched at Titagarh in Kolkata. The launch happened in the presence of Vice Admiral B Sivakumar, Chief of Materiel, along with senior Indian Navy officers and people from Titagarh Rail Systems Limited. The official release says the vessel was launched by Mrs Deepa Sivakumar.

DSC A23
DSC A23 is the fourth vessel out of five Diving Support Crafts being built for the Indian Navy. The deal for these five ships was signed in February 2021 between the Ministry of Defence and Titagarh Rail Systems Limited. These crafts are made for important underwater work near the coast and inside harbours. They help the Navy in diving support, underwater inspection, repair work, salvage jobs, and coastal operations when needed. In simple words, this is the kind of ship that helps when the Navy has to work under the sea, check damage, clear areas, or support rescue-type technical missions.
Built for underwater work near the coast
This vessel is about 30 metres long and has a catamaran-style hull, which means it is built in a way that gives it better balance in water. Its displacement is around 380 tons. Because of this design, the craft gets better stability, more working space on deck, and smoother performance at sea.
That makes it useful for diving operations in coastal waters and harbours where careful technical work is needed. The ship is not a giant warship, but it does a very special job and that job is very important for naval readiness.
Designed in India and tested for safety
The craft has been designed and built under the rules of the Indian Register of Shipping, also called IRS. Before construction moved ahead, the project also went through model testing and hydrodynamic analysis at NSTL in Visakhapatnam. This is important because such testing helps check how the ship will behave in water and whether it can do its job safely and properly.

Make in India
One big reason this project matters is its strong Indian content. According to the official release, 70% of the main and auxiliary equipment in these crafts comes from indigenous manufacturers.
That means a large part of the ship and its systems has been sourced from companies inside India. This helps reduce dependence on foreign imports and supports India’s own defence industry. Projects like DSC A23 show how “Make in India” is moving from policy talk into real naval platforms that can serve on the water.
Important for the Navy
With ships like DSC A23 joining the fleet, the Indian Navy will get stronger support for underwater work in coastal areas. These crafts improve the Navy’s ability to inspect, repair, clear, and recover things from underwater. They also help the Navy stay more prepared during urgent situations near ports and shore-based zones.
