New Delhi, Dec 17: India is constantly upgrading its submarine fleet with modern weapons and sensors, Defence Minister A.K. Antony said Monday.
This was done to "ensure that the combat capacity of the country remains at the desire level", he said in a statement in the Lok Sabha.
"The government has approved the submarine programme to adequately augment (the) submarine fleet of the navy," he said.
The minister was asked if the government had signed any agreement with foreign countries regarding procurement of submarines with state-of-the-art technologies.
He said the government signed a contract in 2005 with Mazagon Dock Ltd, Mumbai, to construct six Scorpene class submarines under Project-75.
Mazago Dock Ltd was building these submarines after signing an accord with a French company, he said.
