India advances proposal for three more Kalvari-class submarines
India is advancing a proposal to build three more Kalvari-class submarines at Mazagon Dockyards Limited, with support from France’s Naval Group.
A modified plan, estimated to cost about ₹33,000 crore, is being submitted to the Cabinet Committee on Security; the source does not say it has been approved.
India already has six submarines of this class.
The proposal had been set aside while India prioritised Project 75(I), a longer-term plan for submarines with air-independent propulsion.
The source says that plan has been delayed, while older Indian submarines are nearing the end of their service life.
It also says Pakistan is expected to acquire eight Yuan-class submarines by 2028 to 2030, adding to pressure on India’s submarine fleet.
If approved, the new order would support submarine-building work and technical skills at the shipyard.
The next step is Cabinet consideration of the revised proposal.

The estimated construction cost is around ₹33,000 crore, and a modified proposal is being put before the Cabinet Committee on Security.

The proposed submarines would initially use lead-acid batteries and could be upgraded to lithium-ion batteries.
