The Arihant class submarine is a  Nuclear Powered ballistic Missile Submarine being developed for the Indian Navy. Arihant meaning “Slayer of Enemies” is India’s first Indigenously built submarine. The hull of the lead vessel of the class, , was introduced to the public on July 26, 2009 at a “launch” ceremony, which consisted of floating it by flooding the dry dock. Presently, the ship is no more than a floating hull, as no nuclear reactor, sensors, or weapons have been fitted and will not be for at least another year, at which point the trials will commence.

The Arihant class is India’s first indigenously designed and built submarine. 3 submarines of the class are expected to be in commission with the Indian Navy by 2015. The Arihant class vessels were designed as a part of India’s US$2.9 billion project to design and build nuclear-powered submarines.

Declaring that India has achieved a “historic milestone in the country’s defence preparedness” with the launch of the submarine, the Prime Minister said, “We don’t have any aggressive designs nor do we seek to threaten anyone.

With the sea trials, India has announced to the world that it possesses underwater platforms capable of launching nuclear weapons, completing its nuclear triad (land, air and sea) capability and strengthening its strategic deterrence.

It also made its entry into an elite club of nations comprising the US, Russia, France, the UK and China , which possess capabilities to develop nuclear submarine.

The 6000-tonne submarine is powered by an 85 megawatt capacity nuclear reactor and can acquire surface speeds of 22 to 28 kmph (12-15 knots) and submerged speed upto 44 kmph (24 knots). It will be carrying a crew of 95 men and will be armed with torpedoes and missiles including 12 ballistic missiles.

INS Arihant can also be armed with cruise missiles. The DRDO is already working on an equally secretive Sagarika project for a 700-km K-15 missile, capable of carrying nuclear weapons.

With new Potent weapons in its Arsenal,India is trying hard to upgrade its Defence structure in order to Defend itself from any form of attack (if comes)from its unstable Neighboring Countries.

From the past,India is Known to have a No first use policy or a defensive policy but at the same time its making sure that if it gets hit,it is ready to give back a Powerful punch which will break the Backbone of the Enemy once in for all.
