The Indian Navy recently celebrated a significant milestone with the launch of the ‘DSC A 22’, the third of five Diving Support Craft (DSC) being developed by Titagarh Rail Systems Ltd (TRSL) in Kolkata. The launch took place on September 12, 2025, and was led by Vice Admiral Suraj Berry. The vessel was ceremonially launched by Mrs. Kangana Berry, adhering to naval traditions.
These craft are designed for diving operations along India’s coast. Each vessel weighs about 380 tons and features a catamaran hull. Equipped with modern diving gear, they will aid the Navy in various missions, such as underwater inspections, search-and-rescue, salvage operations, and repairs.
Each DSC adheres to strict regulations set by the Indian Register of Shipping (IRS). The Naval Science and Technological Laboratory (NSTL) in Visakhapatnam conducted hydrodynamic testing to ensure their performance and safety.
Importance of Diving Support Craft
Diving Support Craft play a crucial role for the Navy. Their capabilities include:
- Conducting underwater inspections of ships and submarines.
- Supporting maintenance of underwater structures.
- Assisting in submarine rescue efforts.
- Conducting salvage operations after maritime incidents.
- Providing disaster relief through underwater clearance.
Their specialized equipment and compact design make them vital for various coastal operations.
Boosting Indigenous Defense
The DSC A 22 launch highlights India’s focus on indigenization, aligning with the ‘Make in India’ and ‘Aatmanirbhar Bharat’ initiatives. By partnering with private shipbuilders like TRSL, the Ministry of Defence is enhancing local manufacturing and reducing reliance on foreign technologies.
Vice Admiral Berry noted the importance of collaboration among shipbuilders, designers, and the Navy to achieve this milestone. Such projects not only elevate operational capabilities but also promote self-reliance in defense technology.
What’s Next?
With DSC A 22 launched, the vessel will undergo outfitting and preparation for sea trials. The remaining ships are in various construction stages, with completion expected in the next two years.
Once all five Diving Support Craft are operational, they will greatly improve the Navy’s readiness in coastal areas. Their presence will strengthen India’s maritime safety and enhance the Navy’s ability to respond to underwater emergencies.
A Step Towards Self-Reliance
The DSC A 22 is a symbol of India’s growing shipbuilding expertise and determination to become a leader in defense manufacturing. By embracing advanced technology and private sector involvement, the project reinforces the Navy’s operational strength and the nation’s commitment to self-sufficiency.
In a recent survey by the Department of Defense Production, 70% of respondents believe that local defense manufacturing is critical for national security. This sentiment underscores the importance of initiatives like the DSC project in bolstering India’s defense capabilities.
