New Delhi (Agencies): The Navy will float a global tender for obtaining six next generation submarines worth over Rs 50,000 crore by the end of this year.

"The government has cleared Project-75 India which is the next lot of six submarines... At the moment we are going with the Request for Information (RFI) process, I hope within this year we would be able to push off the tender," said Navy chief Admiral Nirmal Verma.

Project-75 India is a follow on of the Scorpene submarine project, six of which are being set up by the Mazgaon Dockyards Limited (MDL) under a Rs 20,000 crore deal with French company DCNS.

With a depleted submarine strength, the Navy is planning to induct over 12 submarines in the next 10 to 12 years. The plans have also suffered a jolt in view of the delays in the construction of the Scorpenes in Mumbai.

Talking about the capacities of future submarines, the Navy chief said, "It will be a different boat in the sense that we are revising its Qualitative Requirements. Along with better sensors it will also have better hiding capability, improved detection range and combat management system."

He said the navy would go for the Air Independent Propulsion (AIP) systems for the submarines, which would boost their capability of remaining submerged in water for a longer time period.

On the weapon systems to be put on the next line of underwater vessels, Verma informed Navy was planning to use a blend of indigenous torpedoes along with the missiles which are being deployed on the Scorpene submarines.

To a query on safety of Indian fishermen, he said, "The issue was highlighted during the visit of the Sri Lankan President also. The joint working group on fisheries is supposed to address these issues and that is the way to resolve it."

He denied information of any apprehensions expressed by China on India's forthcoming exercises with the navies of the US and Japan.

On the annual exercise TROPEX, the Admiral said that apart from elements from army and air force, the navy would also include its amphibious elements for the first time in the exercise.

Indian Navy inducted its first amphibious warship INS Jalashwa from the United States in 2007.
