Nuclear bombs and detonations[edit]
Five nuclear devices were detonated during Operation Shakti.[13] They were:[12]
Shakti I – A thermonuclear device yielding 45 kt, but designed for up to 200 kt.
Shakti II – A plutonium implosion design yielding 15 kt and intended as a warhead that could be delivered by bomber or missile. It was an improvement of the device detonated in the 1974 Smiling Buddha (Pokhran-I) test of 1974, developed using simulations on the PARAM supercomputer.
Shakti III – An experimental boosted fission design that used "non-weapon grade"[14] plutonium, but which likely omitted the material required for fusion, yielding 0.3 kt.
Shakti IV- A 0.5 kt experimental device.
Shakti V – A 0.2 kt experimental device that used uranium-233.
An additional, sixth device (Shakti VI) is suspected to have been present but not detonated.[12]
At 3:43 pm IST; three nuclear bombs (specifically, the Shakti I, II and III) were detonated simultaneously, as measured by international seismic monitors.[8] On 13 May, at 12.21 p.m.IST 6:51 UTC, two sub-kiloton devices (Shakti IV and V) were detonated. Due to their very low yield, these explosions were not detected by any seismic station.[8] On 13 May 1998, India declared the series of tests to be over after this
