Titagarh Naval Systems Limited (TNSL), a wholly owned subsidiary of Titagarh Rail Systems Limited, launched the fourth Diving Support Craft (DSC) A23 (YARD 328) for the Indian Navy on 19 April 2026. The vessel was side launched into the Hooghly River at 1455 hrs with about 150 employees present, and it forms part of a series of five DSCs under the Government of India's Make in India initiative. Designed as a catamaran type vessel, the DSC carries indigenously sourced systems to support the Indian Navy's Command Clearance Diving Teams and assist underwater operations. It will undertake inspection, repair, maintenance and salvage within harbour and near shore areas and serve as a training platform for diving personnel. The company said the launch marked steady progress in its commitment to delivering specialised vessels and to strengthening indigenous defence manufacturing and shipbuilding capabilities. Management indicated that the initiative would support consistent delivery of critical platforms and reaffirm the group's focus on maritime growth following corporate restructuring. The move to a dedicated shipbuilding arm was described as enabling sharper strategic focus and expansion. The Indian Navy conveyed appreciation for the collaboration between the service, the shipyard and industry partners and noted that the locally built vessel represented a step towards greater self-reliance in defence manufacturing. Senior naval leadership recognised the engineering and teamwork demonstrated in the project and welcomed the additional platform for diving and underwater operations in coastal waters. The craft's role in enhancing operational preparedness and training was highlighted as a priority. TNSL is developing a modern shipyard at Falta spanning about 50 acres to handle ships up to 180 metres and with an annual capacity of 12 to 16 vessels. The board has approved in principle transfer of shipbuilding and maritime systems business to TNSL, which has an approximate order book above Rs five bn including taxes. The company noted a legacy of more than 35 vessels and said it would pursue partnerships to scale while contributing to the vision of a Viksit Bharat.
