Background

A brief history of the 6 submarine project

The Scorpene class submarines were finalised in 2005, after a need was felt due to the dwindling number of submarines in the navy.

The submarines were to be manufactured in Mazagaon Dock Ltd (MDL) under transfer of technology from France.

The construction of the first of the six submarines started in 2009 after delays and the 1st submarine was ready only in 2015.

India is now left with only 14 submarines, half of which have crossed 3/4th of their operational life, compared to China which has 68 submarines.

The Parliamentary Standing Committee on Defence had expressed dismay at the "snail pace" of commissioning naval vessels.
