As per indications, the RFP for the submarines should be out even in January 2013, or latest by March before the financial year 2012-13 ends.

AIP increases the mission life of a submarine by around three times, depending upon the task and parameters required. The capability enables a submarine to generate air on-board without the need to surface for breathing to recharge its batteries.

The new Project 75-I submarines should be huge in value, estimated at around $10 billion-plus, depending upon the offsets and transfer of technology (ToT).
