On the 25th anniversary of the 1998 Pokhran nuclear tests, Defense Minister Rajnath Singh addressed an event.
He said that through these tests India had sent a message to the world that although India is a peace-loving nation, it would not let anyone harm its sovereignty and integrity. On May 11, 1998, India successfully conducted three nuclear bomb test explosions in Pokhran, Rajasthan. Two more bombs were tested on 13 May. The code name of the 1998 Pokhran nuclear test was Operation Shakti (literally, “strength”). These tests were fully successful in terms of achieving their scientific objectives. It enabled India to build fission and thermonuclear weapons with yields up to 200 kt (kilotons.)
India came out with an official nuclear doctrine in 2003, which clearly explained the 'no first use' policy. With these tests, India entered the club of countries having the capability to deploy nuclear weapons. India conducted its first nuclear test in May 1974. Pokhran-I’s code name was Operation Smiling Buddha. India’s nuclear programme was started by Homi J Bhaba.
