Chief of the Naval Staff Admiral Karambir Singh speaking to the Indian media justified procurement of conventional attack submarine (SSK) from a foreign country under Transfer of Technology (ToT) agreement for the last time under Project-75I so that Public-Private sector ecosystem in the country for the development of local SSK will be created when Directorate of Naval Design (Submarine Design Group) comes up with its design capabilities.

Singh also said that the Navy is yet to master some of the niche techs in subsystem development and level design capabilities that are required for the development of an indigenous SSK program that the Navy plans to achieve after executing the P-75I program for the development of six next-generation conventional attack submarine (SSK). in its previous report had brought out details of the Indian Navy’s plan to develop 6 units of 5MW Propulsion motor from the Original Equipment Manufacturer (OEM) under the Indigenously Designed Developed and Manufactured (IDDM) category. The Propulsion motor draws its power from the main battery of the submarine which eventually drives a propeller through a single shaft. What will be the application of this 5MW Electric Propulsion motor is yet to be revealed but it’s unlikely to be used on the existing submarine fleet in the Indian Navy. Electric Propulsion motors that generate power output for the shaft in a range of 5-6MW are usually seen on Diesel-Electric submarines that have submerged displacement of 3000-4000 metric tons.
