India joined the ranks of maritime nuclear powers on February 3, 1988, with the induction of its first nuclear-powered submarine INS Chakra into the Indian Navy. The submarine was not armed with nuclear weapons and was equipped for training and self-defense. Prime Minister Rajiv Gandhi emphasized the importance of safety measures and peaceful means of conflict resolution. The INS Chakra belonged to the Victor 1 SSN class of submarines and had a speed of 32 knots when submerged. India may acquire more advanced submarines in the future.
