Pokhran-II was the series of five nuclear bomb test explosions. It consisted of five detonations, of which the first was a fusion bomb and the remaining four were fission bombs. These nuclear tests resulted in a variety of sanctions against India by a number of major states, including Japan and the United States.
Many names are attributed to these tests; originally they were called Operation Shakti–98 (Power–98), and the five nuclear bombs were designated Shakti-I through Shakti-V. More recently, the operation as a whole has come to be known as Pokhran II.
