The Indian Navy is considering a proposal to equip Scorpene submarines, which are under construction, with an air independent propulsion (AIP) system to overcome the risk of detection.
The system, which is being built at Mazagon Dock, enables the boats to stay underwater without having to surface for more than three weeks.
DCNS CEO Patrick Boissier said the company was in talks with the navy and that the system could be integrated into the fifth and sixth submarines in 2018.
The navy is also looking at an indigenous AIP system, which is being developed by the Defence Research and Development Organisation, according to Hindustan Times.
The first Scorpene submarine is expected to enter service in 2015 and the remaining within a span of three years.
India is constructing six Scorpene submarines with transfer of technology from DCNS under a Rs187.98bn ($4.16bn) programme called Project 75.
