I’m torn with submarine names for the MX-SSB class, a real proposed design that I’m using in All Union

(Bottom picture made in Stable Diffusion from the outline of the sub above)

The problems are:

• The class is large at circa 50 boats, so the naming scheme needs to support such a large class.
• There is no historical precedent since the US never used diesel missile subs, much less in large numbers.
• Both fish and people just don’t seem right to me (subjective I know)

I’m leaning towards lakes (ie, the Lake Tahoe class with some/all of the Great Lakes thrown in), but am wondering if there’s something that just can click. Thoughts?
