IN activates reactor on locally built SSBN

12 August 2013

India edged closer to confirming its three-tier strategic deterrence on 10 August by activating the reactor aboard INS Arihant , its indigenously developed nuclear-powered ballistic missile submarine (SSBN), at the secretive Ship Building Centre (SBC) in Visakhapatnam on the East Coast.

Indian Navy (IN) officials said that with the SSBN's 83 MW pressurised light water reactor (LWR) fuelled going 'critical', the 6,000-ton Arihant (meaning 'Slayer of Enemies') will shortly begin sea trials before joining fleet service around 2015.

These trials, following extended delays of over a decade, will include test firing of the K-15 nuclear-capable, two-stage submarine-launched ballistic missile (SLBM), which has a strike range of 700 km.
