1 SSBN S-5 :- India's next Generation Nuclear Powered Ballistic Missile submarine — Indian Defence Update

SSBN S-5 :- India’s next Generation Nuclear Powered Ballistic Missile submarine

A follow-on class of 6 SSBNs codenamed S5, almost twice as big as the Arihant-class, was also approved for development. These will be able to carry up to 12 K5 intercontinental ballistic missiles with MIRV warheads.

India Navy already has started working on the successor of Aridhaman Ballistic Missile Class Submarine at least a decade ago and new larger Ballistic Missile Class which will be designated as S5 and will be as big as Ohio class nuclear-powered submarines currently used by the United States Navy. It is unclear how many S5 sister class ships will be developed at this point in time but the construction of the new class of SSBN is yet to commence and it is likely will go on the floor for nearly a decade from now.

Indian Navy is concentrating on the development of current ssbn of arihant class that will give Indian Navy at least 4 submarines & after its completion around 2022-23 and then indian navy will start developing S5 nuclear Submarine.If the program sticks to its schedules and doesn’t face any delays then tentatively the first lead submarine will be ready for launch by end of next decade. S5 will also require new reactor and BARC will upscale current 83MW Pressurized water reactor (PWR) from Arihant class to 190 MW to meet the power demands of the larger vessel.

Each S5 will have Average construction timeframe of 8 years and lead submarine S5 might take little longer time initially but India might start work on 2 Submarines at a time to reduce their developmental time.

India will be having a fleet of following numbers of Nuclear Submarines in near future :
1 SSBN’s of Arihant Class +3 SSBN’s of Aridhaman Class + 2 S5 SSBN’s apart from that 6 new SSN’s + INS Chakra and 1 more to be leased from Russia.

Last year Indian Navy was given go head to start design work on the development of Six new Nuclear attack Class Submarines which will be developed in parallel to the Ballistic Missile Class Submarine Fleet so that work on both the projects will continue independently.

Early this year, the government cleared a project to build six new hunter killer boats (SSN) for the Navy. A joint Navy, BARC and DRDO project, the boats will be designed by Navy’s Directorate of Naval Design and be powered by a new reactor being developed by BARC. SSNs are as important as SSBNs as they can blockade important sea routes, denying the enemy access to important resources in an event of war, and shadow enemy ships
India’s first line of Indigenous nuclear attack submarine will have more in common with Arihant class Ballistic missile submarines (SSBN) then Akula class nuclear attack submarines. As per report India’s six new nuclear-powered attack submarines (SSN) will borrow 83 MW Pressurized water reactor (PWR) from Arihant class and will have a similar surface displacement of over 6000 tonnes.. Also, India is likely to lease another Akula II for 10 years in 2018, most likely the Kashalot that is 60% complete and in need of funds.

Unnamed Six Nuclear attack Class Submarines SSN are required to be much stealthier to do sneak attack and surveillance roles and it is reported that construction of Scorpene class Diesel attack submarines in India has helped Naval Design Bureau a lot in obtaining technical know how to better understand and develop stealthier hull.

The SSN are designed to track down and defeat both, the SSBN and the enemy aggression. These submarines are used in the attack of particular targets on land by the launch of the fast missiles by use of the torpedo tubes.

The Submersible Ship Nuclear carries the cruise missile with explosives which are used to attack the assailants within the shores. The other purpose of the submarine ship is to conduct surveillance, perform and complete intelligence missions, so they can offer aid in highly classified operations. The size of this ship is moderately big. The SSN is used to make attacks to assailants in the nearby distance. It is considered war prone and looks for enemy ships to destroy them
