In this episode, host Dev Goswami and defence expert Shiv Aroor delve into India's nuclear submarine program, discussing its limited fleet despite a vast coastline of 6700 km. Why does a country with such a significant maritime border suffer from "sea blindness"? The Indian Navy, the smallest among the three armed forces, seems disproportionally under-equipped given the strategic importance of its maritime domain. So, what factors contributed to this stagnation?India currently boasts only two nuclear submarines, INS Arihant and INS Arighat. But what sets nuclear submarines apart from their conventional and diesel-electric counterparts?Consider this a masterclass on the SSBNs (nuclear-powered ballistic missile submarines) and SSNs (nuclear-powered attack submarines).In February 2015, the Indian government approved the indigenous construction of six SSNs at the Ship Building Center (SBC) in Visakhapatnam. But we have yet to hear much about these projects since then. The absence of a nuclear-powered attack submarine in India's fleet has significant strategic implications. Why hasn't India yet commissioned one despite the urgency?Tune in!Produced by Anna PriyadarshiniSound mix by Sachin Dwivedi
