Arihant was often called Technology demonstrator for India’s ship submersible ballistic, nuclear (SSBN) program and Arighat is a much more refined submarine that has enhanced capabilities.It’s no hidden fact that the Navy plans to use Arihant as a Training vessel for the training of future crew to operate nuclear-powered submarines when bigger S4 and S4* joins the fleet and later prepare for induction of the larger S5 class of submarines. S4 and S4* will be first-in-class submarines that will enable the Indian Navy to carry bigger China-specific nuclear ballistic missile-like K5 (5000km) and K6 (8000km).
