India Weighs More Scorpenes as Six-Submarine Deal Nears Approval
India is considering building six new submarines in the country with help from a German company.
The plan, called Project-75(I), is worth more than ₹80,000 crore and is waiting for a final government decision.
India is also considering three more Scorpene submarines, but that plan is not as far along.
The Navy wants to add a home-developed system to one Scorpene during a repair period around the middle of next year.
This system could help the submarine stay underwater longer without coming to the surface.
Another Indian-made system for submarine combat is also planned for installation during future refits.
These efforts combine new submarines with upgrades to boats already in service.
India is monitoring Pakistan’s plans to induct Hangor-class submarines, built with Chinese assistance.
Project-75(I), estimated at more than ₹80,000 crore, would build six advanced conventional submarines in India with German firm TKMS.
Defence Secretary Rajesh Kumar Singh said Project-75(I) is at the final stage and awaits a decision by the competent authority.
India is also considering three additional Scorpene submarines for construction at Mazagon Dock Limited in Mumbai; the proposal is less advanced.
The Navy plans to test a DRDO-developed indigenous AIP system on a Scorpene-class submarine during a refit around the middle of next year.
NPOL has developed an indigenous integrated submarine combat system that the Navy plans to introduce progressively during refits.
