The ‘Akula’ is the original Russian name for what is popularly called the Typhoon class SSBN (Which is what is being discussed here). The Typhoon is the NATO codename for that boat, Akula is the NATO codename for the BARS class SSN.
Thanks for the answer. Interesting insight into how the allied naval intelligence agencies were dropping the ball in the 70s leading to such confusion.
>>> The Russian naval fleet at present comprises of three Project 941 Akula class (NATO name Typhoon)
And a PS for my own confusion, missing that line on the first read.
