Vice Admiral Srinivas Kalidoss (Retd), Director General of the Advanced Technology Vessel Programme (ATVP), embarked on a significant visit to the Naval Science and Technological Laboratory (NSTL) in Visakhapatnam on January 25, 2024. The purpose of his visit was to inspect the hydrodynamic test models of various Indian submarines, shedding light on the advancements and innovations within India’s naval defense sector.

The hydrodynamic test models showcased at NSTL represent a crucial aspect of submarine development, enabling engineers and designers to assess the performance and efficiency of underwater vessels under varying conditions. These models serve as invaluable tools in refining the design and engineering of submarines, ensuring optimal functionality and operational capabilities in real-world scenarios.

However, it is important to note that the existence of hydrodynamic test models does not imply an exact replication of submarines such as the S4 and S5 SSBN currently under development to bolster India’s Nuclear Triad. While these models provide valuable insights into the hydrodynamic properties of submarines, they are not comprehensive replicas of the sophisticated vessels being developed to enhance India’s strategic defense capabilities.

The S4 and S5 SSBN submarines represent the pinnacle of India’s naval prowess, designed to play a pivotal role in the country’s nuclear deterrence strategy. As integral components of India’s Nuclear Triad, these submarines are engineered to operate seamlessly across strategic and tactical domains, ensuring the nation’s readiness to respond effectively to emerging security challenges.

While the hydrodynamic test models showcased at NSTL offer valuable insights into submarine design and performance, the true significance lies in their contribution to the broader framework of naval modernization and strategic deterrence. As India continues to invest in cutting-edge technologies and capabilities, the development of advanced submarines remains a cornerstone of its defense doctrine, ensuring the nation’s ability to navigate complex security challenges and uphold regional stability.
