In 2005, India chose the Scorpène' design; purchasing six for US$ 3 billion (US$500m per boat). These submarines are to be manufactured under a technology transfer agreement by the state-owned Mazgoan Docks in Mumbai and delivered between 2010 and 2015. 
Scorpène class submarines are a class of diesel-electric attack submarine jointly developed by the French DCN and the Spanish company Navantia and now by DCNS. It features diesel propulsion and an additional air-independent propulsion (AIP)...

The 1750 ton displacement Scorpene is 67 meters long and equipped with six 21 inch torpedo tubes that can launch 12 torpedoes or anti-ship missiles.

Scorpene submarines incorporate acoustic discretion and combat system performance technologies developed for nuclear-powered classes operated by the French Navy. They feature a modular design and excellent endurance. They are claimed to be one of the few medium-displacement designs suitable for extended ocean patrol duties.

The Scorpenes made at MDL will be equipped with Exocet SM39 missiles capable of being launched from its torpedo tubes.A proposal to fit an additional section in the submarine for vertically launched Brahmos missiles was shelved with the Navy preferring an AIP unit instead.

Air Independent Propulsion
The Indian Navy has asked MDL to equip the fifth and sixth boats with Air Independent Propulsion, which will require the addition of new section. During his visit to India with French President Nicolas Sarkozy in December 2010, DCNS CEO Patrick Boissier said that if a contract were to be placed on DCNS by next year, AIP systems could be integrated into the fifth and the sixth submarines rolling out of MDL in 2018.The four Scorpenes launched earlier could be retrofitted under an upgrade program.The Navy is also looking at an indigenous AIP kit under development by DRDO.

India floated a request for information under the project in 2008 for acquisition of six AIP equipped submarines with high degree of stealth and land-attack capability.India will follow up its acquisition of six Scorpene submarines under Project 75 with an additional six AIP equipped subs under Project 75I (Project 75 India).The project is expected to be worth $10 billion.
Qualitative Requirements

"They will also have high degree of stealth, land-attack capability and ability to incorporate futuristic technologies. Like the Scorpenes, they will be built in an Indian shipyard, public or private, with special emphasis on full transfer of technology," said a source. 

Brahmos Launch Capability
A key differentiator in the submarines acquired under Project 75A would be their ability to launch missiles from under water. The Brahmos is likely to be the Indian choice for the missile.

Vendors Under Consideration
Foreign vendors being considered for supplying the subs are Russia’s Rosoboronexport, France’s DCNS, Germany’s HDW and Spain's Navantia.
France's DCNS, hopes to be leading contender for the new order. It is already supplying six Scorpene submarines to India under a 2.4 billion eur contract signed in 2005. These subs, being assembled at Mazagaon docks, are to be commissioned in the Navy from 2013 through 2018.The 1750 ton displacement Scorpene is 67 meters long and equipped with 12 torpedoes and 6 anti-ship missiles.The MESMA module is fitted as an additional hull section with in Scorpene which then measures 76.10 meters long and displaces 2000 tons.


In November 2010 it was reported that Russia's Rosoboronexport will offer Amur-1650, its 4th generation diesel powered submarine against the Indian tender.

Amur-1650 Capabilities
Developed by Rubin Central Design Bureau for Marine Engineering, Amur-1650 has acoustic field rate that is many times lower than that of Project 877/636 diesel subs.Project 877/636 Kilo class diesel subs reportedly have a noise level of 105 decibels. Seawolf class nuclear subs have a noise level of 95 decibels, the lowest for any submarine. The background noise of the ocean is 90 decibels.Armed with 6 torpedo tubes, the Amur-1650 can go to a depth of 300 meters. It is manned by a crew of 35 hand has an endurance of 45 days.According to the August 22, 2011 issue of Russia & India Report, the Rubin Design Bureau is creating a special version of Russia’s new Project 677 (?mur class) submarine to carry BrahMos anti-ship missiles as its main weapon system, in order to make the sub competitive for Project 75I.

(I)INS CHAKRA (Akula 2 / Nerpa) nuclear submarine

Nerpa is the Project 971 third-generation submarine (NATO code name Akula-II), the most advanced Russian nuclear attack submarine. Construction of the 8,140-tonne Akula II class Nerpa nuclear attack submarine started in 1991 but was suspended for over a decade due to lack of funding.
Akula II class vessels are considered the quietest and deadliest of Russian nuclear-powered attack submarines. They feature a double-hull, with considerable distance between the outer and inner hulls to reduce the possible damage to the inner hull, and. a distinctive high aft fin.
Its armaments consist of four 650mm torpedo tubes, with 12 Type 65 torpedoes or SS-N-16 Stallion missiles, and four 533mm tubes, with 28 Type 53 torpedoes or the SS-N-15 Starfish missiles.

Torpedoes can also be replaced with submarine mines, rocket-assisted torpedoes, and a variety of other submersibles. 

The Indian version is expected to be armed with the 300-km Club nuclear-capable missiles.

It is not known if India will receive Shkval rocket-assisted torpedoes.

The Akula II is able to dive deeper than any other modern SSN.


Terming the sea-based variant as "most survivable" and "least vulnerable" of the nuclear triad, the Navy Chief said the launch of the Arihant was a significant step towards achieving that capability.

India's nuclear doctrine calls for a minimum credible nuclear deterrent in form of a survivable triad, of land, sea and air based platforms that can deliver a second strike in case of nuclear attack by the enemy as it follows a 'no first strike' policy.
The SSBN will be commissioned into the Navy in two years after completion of sea trials.

At a glance

Displacement: 6,000 tons
Length: 112m
Beam: 10m
Powerplant: 83 MWe PWR
Crew: 95
Surface Speed: 12-15 kts
Submerged Speed: 24 kts
Armament: 12 K-15 Sagarika missile, Torpedos, Torpedo launched cruise missiles, four K-4 missiles 

Weapon fit
The ATV will reportedly be equipped with 12 launch tubes of 2.4m diameter each. Initially, each missile tube will likely accommodate 3 0.74m diameter K-15 Sagarika missile. Later the tubes could accommodate the 2.0m diameter Agni IIISL (The submarine launched version of the Agni V / Agni 3+) missiles with MIRV capability.

Sagarika has a range of approximately 700 km (435 miles). It was last tested on February 26, 2008, off the coast of Visakhapatnam from a pontoon simulating the conditions of a submarine.
In addition to ballistic missiles, Arihant will eventually also have the capability to launch curise missiles through its torpedo tubes.

The Navy hopes to induct the first ATV by 2012.

this is a list of top 10 war detterent weapons of india ,plz dont confuse it with top 10 future weapons of india.This list has sorted according to it's significance it holds in future war .Many weapons i have unneccessary not included so that the thread doesnt becomes clumsy & lenghty,but still then if i by chance had missed out any weapon or u want to change the list then plz comment.
I hope u would appreciate my hard work.THANK YOU
