INS Arihant Nuclear Powered Ballisitc Missile Submarine,Indian Navy

INS Arihant is the lead ship of India’s Arihant class of nuclear-powered ballistic missile submarines. The 6,000 tonne India’s first nuclear-powered and nuclear-armed submarine INS Arihant was built under the Advanced Technology Vessel (ATV) project at the Ship Building Centre in Visakhapatnam, based on the Russian Akula-1 design.

 INS Arihant was introduced to the public on 26 July 2009 at a symbolic launch ceremony by then Prime Minister Manmohan Singh’s wife Gursharan Kaur. The launch coincided with the tenth anniversary of the conclusion of the Kargil War and consisted of floating the vessel by flooding the dry dock.

India is in the process of constructing two more Arihant-class submarines.

Need of Building Nuclear Powered Submarine

Construction of INS Arihant is considered to be a giant proceed of Indian to secure a seaborne nuclear deterrent.The nuclear powered submarine will help Indian achieve the capability of going into high seas without the need to surface the vessel for long durations.

As  conventional diesel-electric submarines have to come up on surface at regular intervals for charging the cells of the vessel,The nuclear powered submarines will stay underwater as longer according to need.

India is the only nation in the Indian Ocean region to have a nuclear submarine and the sixth in the world to have the capability to design and construct a nuclear submarine.

Design and Development

The design of Arhiant-Class submarines are reported to be based on the Akula-class submarine.The crew before working on INS Arihant will be trained on INS Chakra,an Akula-class submarine which the Indian Navy Leased from Russia.According to Admiral Niraml Verma the INS AriHant is more of “a Technology Demonstrator” rather than a fully operational SSBN.

All the sections of submarines were built at different places.AS the vessel is powered by nuclear reactor with enriched uranium fuel,the land-based prototype of reactor was first built at Kalpakkam and made operational in September 2006.The 80MW nuclear reactor was integrated into the Hull of ATV after three years successfully operating in January 2008.The hull for vessel was built by L&T’s Hazira shipbuilding facility.

Tata Power built the control systems for the submarine. The systems for the steam turbine integrated with the reactor are supplied by Walchandnagar Industries.[15] The consultancy for this project was provided by Russia.Russia was also reported to have provided assistance to BARC scientists in miniaturising the reactor to fit into the hull of the nuclear submarine

As per Defence Minister Manohar Parrikar, the sea trials of INS Arihant will last for 8 to 10 months, before its induction and commissioning into the Indian Navy in the last quarter of 2015.

Features and Propulsion

The Arihant class ballistic missile submarine has 111m long ,Beam length of 15m and draft of 11m and has surface displacement of 6000 tonnes.It has installed power unit that can capable of creating 83 Mwatt of power.One turbine one shaft one-7 bladed high skew propeller is responsible for the propulsion.The 83 megawatts pressurised light-water nuclear reactor with 40% enriched uranium fuel  propelled this submarine.It has the unlimited range except by food supplies.It has crew of 95-100 members .The INS Arihant can acquire surface speeds of 12k to 15k and submerged speeds up to 24k.

The submarine has the special USHUS sonar that is used to detect enemy ships and subs ,The USHUS is an integrated sonar system developed by the Naval Physical and Oceanographic Laboratory (NPOL) of the Defence Research and Development Organisation (DRDO), India, for use in submarines of the Indian Navy.It is used for detecting and tracking enemy submarines, surface vessels, and torpedoes and can be used for underwater communication and avoiding obstacles.It can detect both surface ships and submarines at a range of a few kilometers.

Armaments

The 9000Tonne vessel is armed with 6 X 533 mm torpedoes and 12 X K-15 Sagarika SLBM (nuclear-capable submarine-launched ballistic missile with a range of 700 kilometres (435 mi)) that is used to destroy ships and other submarines.Larger 4 x K-4 missiles with  longer range of 3,500 km (2,200 mi) also armed with vessel.

Latest Missile Testing on INS Arihant

INS Arihant is set to carry out its first missile firing this year, enabling the country to launch a nuclear missile from air, land, and sea.INS Arihant is expected to fire domestically manufactured medium-range missile B-05, which is capable of carrying a nuclear-tipped warhead.

Defence Research Development and Organisation (DRDO) director general Dr S Chirstopher was quoted by Tribune News Service as saying: “The vessel is slated for deep diving tests and the missile named ‘B-05’ is to be test-fired from the vessel. These tests will be done within this year.”

The B-05 will be India’s first submarine launched ballistic missile (SLBM) and the scheduled test firing will mark the completion of the country’s nuclear triad.
