India to place $11bn order for AIP hi-tech submarines
15th July 2010
Indian defence chiefs have approved $11bn of funds to boost the country’s submarine fleet. The cash is intended to see India become the first non-Western nation to deploy long-touted, much feared “air independent propulsion” (AIP) submarine technology.
Back in World War II, nuclear propulsion wasn’t an option. Nazi engineers instead experimented with chemically powered AIP, in their case the system developed by Professor Hellmuth Walter. Oxygen from air was replaced by the use of hydrogen peroxide, an explosive oxidiser sometimes used in torpedoes or rockets, burned together with fuel oil in a special turbine.

Can anyone explain exactly why India needs submarines?

In a word: China.
