Indigenous nuclear submarine INS Arihant (destroyer of enemies) is all set for sea trials in the coming weeks. Its pressurised water reactor is slated to go critical allowing the 6,000-tonne undersea platform to complete its last stage of testing called sea trails that includes operating the vessel in all possible scenarios, its mandated depth, its sonars and radars. This will include testing of on board missiles and weapons, including nuclear-tipped ones.
If everything goes on track, sea trails of the Arihant could commence anytime within four weeks to eight weeks from now. The miniaturisation of the reactor was a challenge that has been overcome.
Sea trails had to be delayed a few times due to technical reasons. On December 3, Naval Chief Admiral DK Joshi said harbour acceptance trials for the under-development vessel had been completed. We expect to have good news for the nation very soon, he had added.
Arihant, launched in July 2009 at Visakhapatnam, is first of the series of three ballistic missile submarines (SSBN) that India proposes to build at a cost of Rs 30,000 crore.
Induction of Arihant into the fleet would complete the crucial third leg of Indias nuclear triad-the ability to fire nuclear weapons from land, air and sea. Sea trials of Arihant will be globally watched even as India will enter the exclusive club of nations that have the capacity to build nuclear-powered submarines. Only the US, Russia, the UK, France and China have the technology, at present.
Though India is still building a nuclear-powder submarine-considered to be a very complex technology-its Navy has a fully integrated Akula class nuclear submarine, the INS Chakra, leased from Russia for 10 years.
New Delhi has already announced that the INS Arihant will go on deterrent patrol aimed at providing the ability of a retaliatory second strike in case of a nuclear attack. The submarine will carry its full load of nuclear-tipped missiles that can be launched from under the sea.
The Defence Research and Development Organisation (DRDO) has already announced that it has successfully developed nuclear-tipped submarine-launched ballistic missiles (SLBMs). The project was a closely guarded secret at the development stage and was called the Sagarika Project or by its code name the K-15. This has been tested several times using a pressurised canister submerged under water to mimic a submarine-style launch. So far, countries like the US, Russia, France, China and the UK have the capability to launch a submarine-based ballistic missile.
