Explanation: India's first nuclear test, codenamed "Smiling Buddha," was conducted on May 18, 1974, at the Pokhran Test Range in Rajasthan. This event marked a significant milestone in India's nuclear program and established the country as a nuclear power. The test was a peaceful nuclear explosion (PNE) and was conducted to demonstrate India's scientific and technological capabilities.
The Pokhran Test Range, located in the Thar Desert of Rajasthan, was chosen for its remote and secure location. The test was conducted under the leadership of Dr. Raja Ramanna, who was the director of the Bhabha Atomic Research Centre (BARC) at the time. The nuclear device used in the test was a plutonium implosion-type device, which had a yield of approximately 12 kilotons.
The decision to conduct the nuclear test was driven by several factors, including the desire to enhance India's national security and to counter the nuclear capabilities of neighboring countries. The test was also seen as a means to assert India's scientific and technological prowess on the global stage.
Following the test, India maintained a policy of "no first use" of nuclear weapons and has since developed a credible minimum deterrent. The Pokhran test was a significant event in the history of India's nuclear program and has had lasting implications for the country's security and international relations.
It is important to note that the year 1974 is the correct date for this event, and students should be careful not to confuse it with other significant historical events in India. The Pokhran test is a crucial part of India's history and is often tested in competitive examinations such as the UPSC, SSC, and State PSC exams.
