The so-called Smiling Buddha was the first test fission explosion by India on May 18, 1974.On September 7, 1972, Prime Minister Indira Gandhi gave authorization to the scientists at the Bhabha Atomic Research Center (BARC) to manufacture the nuclear device they had designed and prepare it for a test. Throughout its development, the device was formally called the "Peaceful Nuclear Explosive," but it was usually referred to as the Smiling Buddha.
The head of the development team was Raja Ramanna. Other key members were P.K. Iyengar, Rajagopala Chidambaram, and Dr. Nagapattinam Sambasiva Venkatesan. The project employed no more than 75 scientists and engineers from 1967 - 1974.
The device used a high explosive implosion system developed at the DRDO Terminal Ballistics Research Laboratory (TBRL) in Chandigarh based on the American design from WWII. But the Indian design was simpler and less sophisticated than the American system. The 6 kg of Plutonium came from the Cirus reactor at BARC. The neutron initiator was a Polonium- Beryllium type (again like those used in early U.S. bombs) code-named "Flower." The complete core was assembled in Trombay before transportation to the test site.
The fully assembled device was hexagonal, 1.25 m in diameter and weighed 1400 kg. The device was detonated at 8.05 a.m. in a shaft 107 m under the army Pokhran test range in the Thar Desert, RajasthanDate of formation 1948 Capital Jaipur Governor Pratibha Patil Chief Minister Vasundhara Raje Scindia Area 342,239 kmē Rajasthan ( is the geographically largest state in northwestern India.
