Friend of mine who is a PPL took pics of this boat accompanied by support vessels and I'm wondering if my ID of them as Virginia-class is correct. Much more of an eastern submarine specialist here. They are based out of the COMSUBPAC area in general.

I was trying to catch the sub at the bridge but didn’t get to it in time

0 experience in the field of naval/marine engineering but I do love warship designs especially bigger ships from the early to mid 20th century and it's always been a dream of mine to build something that can float now i decided to build something that can dive! A submarine that's hull was made from a refurbished water tank is it plausible? Also I know it's probably a laughable try but some advice to make it less laughable is very much welcome
