India Conducts Pokhran Nuclear Weapons Tests
Following India's 1974 peaceful nuclear explosion and amid regional security concerns, the government under Prime Minister Atal Bihari Vajpayee pursued advanced weapons development in secrecy. On May 11, 1998, three devices—a fission bomb, a low-yield device, and a thermonuclear device—were detonated simultaneously underground at the Pokhran test range in Rajasthan. The tests, part of Operation Shakti, produced measured yields consistent with expectations and no atmospheric release. Two additional sub-kiloton tests followed on May 13. International reactions included sanctions but also recognition of India's nuclear capabilities.
