The Arihant -class (transl. 'Slayer of Enemies' in Sanskrit ) is a class of Indian nuclear-powered ballistic missile submarines being built for the Indian Navy . They were developed under the ₹ 900 billion (US$11 billion) Advanced Technology Vessel (ATV) project to design and build nuclear-powered submarines.[ 1] These vessels are classified as 'strategic strike nuclear submarines' by India.[ 13] [ 14]
The lead vessel of the class, INS Arihant was laid down in 2004, launched in 2009 and after extensive sea trials was confirmed to be commissioned in August 2016.[ 15] [ 16] [ 17]
Arihant holds the distinction of being the first ballistic missile submarine to have been built by a country other than one of the five permanent members of the United Nations Security Council .[ 18]
