It is because only length of sub is confirmed while other dimensions are just thought & guess of people. And I don't think it's size will be greater than Akula(due to weight consideration) It can be compared with George Washington class submarine to a certain extent in size.Submerged akula's displacement exceeds 12500 tons....
Isn't displacement directly related to diamensions of submarine ???
If you look at the data , arihant has larger diamensions than other two ....still even the surfaced displacement is less..
Something fishy ........
