My December 1991 article on India's nuclear submarine project

To the best of my knowledge this was the first article written on the project. As you can see, I argued that the Indian design is based on the Charlie II. The current information suggests that I am right.
I assumed, however, that India would go in for a cruise missile sub which the Charlie is. But it has actually gone for a ballistic misssile one. That makes sense because the greatest advantage of a boomer is when it is a nuclear weapons platform.
