The indigenous 6,000-ton(Destroyer of Enemies) was unveiled in 2009 as part of a project to construct five such vessels which would be armed with nuclear-tipped missiles and torpedoes.
"Arihant is steadily progressing towards operationalisation, and we hope to commence sea trials in the coming months,"told reporters.
"Our maritime and nuclear doctrine will then be aligned to ensure that our nuclear insurance comes from the sea," Verma said,
Arihant is powered by an 85-megawattand can reach 44 kilometres an hour (24 knots), according to defence officials. It will carry a 95-member crew.
The Indian navy inducted a Russian-leased nuclear submarine into service in April this year, joining China, France, the United States, Britain and Russia in the elite club of countries with nuclear-powered vessels.
Verma said 43 warships were currently under construction at local shipyards while the first of six Franco-Spanish Scorpene submarines under contract would join the Indian navy in 2015 and the sixth by 2018.
The admiral said the navy was also poised to induct eight Boeing long-range maritime reconnaissance P-8I aircraft next year.
