No but if you read the work by Stephen Cohen you''ll realize the reason for Indias test in 1998 were designed for the trigger or was it button? Which basically is the hardest part in designing a nuclear bomb expecially today with computer triggers, so the trigger is more accurate.Any proof?or is this one of those "we have no proof, but we can do it". Like India has no ASAT missile. But we have it. We just don't want to send someone to the moon, but we have that capability...
Source: India expanding nuclear arsenal: U.S.
Technical science aside, basically the Indians have Thermo and Fusion bombs or any other nuclear bomb that can be built using this trigger. Trick is to make it accurate for which the Indians atleast for now are comfortable they achieved.
Hence even why US, Russia, China all stopped nuke tests around the time of micro computers exception I think was france?
This all aside, argueing yeild or type of nuclear bomb is usless when dealing with a threat of a nuclear war!
1 nuke is enough which is why India and China do no have many compared to US or Russia nore does India or China intend to have as many. Fact Russia, and America now both regret their large nuclear arsenal.
They are unusable weapons, because once they are used, logic and reason go out the window, hence this world order.
Also India does like China have limited ASAT capability but not like what the US has with its missile shield AEGIS etc.
Problem with shooting down satieletes is that sometimes they are too far away or moving too fast and in space these things are huge in proportion hence why the Americans, RUssians or Europeans and Indians are not concerned about shooting down enemy sats. Space wars are yet to be clearly defined as well. Chinas ASAT test was nothing but a test. Most likily for a BMD shield. Like wise India skipped step like shooting a sat whose tragectory is known. Do some research on Indias BMD program.
