Explanations:The Pokhran-II nuclear tests were a series of five nuclear bomb test explosions conducted by India in May 1998 at the Indian Army's Pokhran Test Range in Rajasthan. This series of tests was a significant milestone in India's nuclear program and was led by Abdul Kalam and R Chidambaram. The tests were conducted in two phases: the first phase on May 11, 1998, and the second phase on May 13, 1998.
The first phase of Pokhran-II involved three tests: one thermonuclear device and two fission devices. The thermonuclear device was codenamed "Shakti-I," and the two fission devices were codenamed "Shakti-II" and "Shakti-III." The second phase involved two additional fission devices, codenamed "Shakti-IV" and "Shakti-V."
These tests were a response to the perceived nuclear threat from neighboring countries and were aimed at demonstrating India's nuclear capabilities. The successful completion of Pokhran-II marked a significant shift in India's nuclear policy and led to international sanctions and diplomatic reactions.
It is important to distinguish Pokhran-II from earlier nuclear tests conducted by India. The first nuclear test, known as "Smiling Buddha," was conducted in 1974 and was a single test. Pokhran-II, on the other hand, was a series of tests conducted in 1998, involving multiple devices and phases.
Understanding the context and details of Pokhran-II is crucial for students preparing for competitive exams, as it is a significant event in India's nuclear history and has implications for national security and international relations.
