India Completes Nuclear Triad with INS Arihant

India has completed its long awaited nuclear weapons triad after commissioning the indigenous nuclear submarine INS Arihant into service, becoming the 6th country to join the elite nuclear triad club.

According to sources, the 6,000-tonne submarine INS Arihant was formally commissioned by Navy Chief Admiral Sunil Lanba in August.

The nuclear triad gives India the capability to respond to nuclear strikes from sea, land and air-based systems.

Based on a clearly declared policy of “no first-use” of nuclear weapons, INS Arihant gives second-strike capability to India.

INS Arihant is India’s first indigenous nuclear submarine, and the lead ship of Arihant class of nuclear-powered ballistic missile submarines launched in 2009.

Initially expected to go for sea trials by 2012, it happened only in December 2014.

Nuclear submarines have the capability to stay out at sea longer, and don’t need to surface for a long duration while conventional diesel-electric submarines have to come up to the surface at regular intervals for charging their batteries.
