Any one can change anything in wikipedia. So wikipedia is not a reliable source. Here is how you can find something from a reliable source
What To Make of India’s Nuclear Forces | Flashpoints | The Diplomat
To be sure, India has a long way to go before it can be confident in deterring, say, China with a fleet of nuclear-powered, nuclear-armed submarines, or SSBNs. For now, its sole SSBN, is basically a technology demonstrator. It's not clear if the INS Arihant, notionally launched in 2009, will ever really conduct deterrent patrols.
And there are serious technical challenges ahead in arming this vessel or the 3-6 such boats the Indian Navy hopes for in its future fleet. As Andrew Winner has asked, can India miniaturize a nuclear warhead to fit these relatively small missiles, and can it do so without further nuclear testing? Is New Delhi stuck with the relatively modest range of this armament? And what does that mean for its ability to genuinely deter China, given the risks of having to patrol close to the Chinese coast in some hypothetical future crisis?
But the blog is not reliable sourceas well. However, the blog site the following book, which is a reliable source. The source state that India has no miniature warhead to put on missiles.
Strategy in the Second Nuclear Age | Georgetown University Press
No Indians had posted anything besides wikipedia or Indian press, which is not reliable. My comments above are from a books. They clearly state that India has no miniaturization tech for nuclear warheads.
