That's what capability Pakistan is seeking to achieve. But the biggest question is in what capacity it will be achieved?
Is housing short range sea launched cruise missiles in diesel electric subs the complete answer?
I don't think so. At best, it will give sea based nuclear strike capability, a stop gap measure. For assured sea borne second and third strike capability with massive destructive potential, nuclear propulsion with longer range missiles and more missile payload are essential. (3,4 SSGN/SSBN units). I hope, in longer run, we will develop such capability.
