What's in a name?Oh, I'm glad you guys are posting about sub names, 'cause this (totally random, trivial) thought occurred to me the other day and I forgot to post this question--delete this post if someone's already addressed this...
What do the letters in the submarine designators "SSN" or "SSBN" stand for--specifically, I want to know why the Navy doubles the letters on some occasions and other times does not. I know, of course, that the attributes of the ship (i.e. that it is "nuclear" or carries ballistic or guided missiles) is usually tacked on to the end. That's fine. But why the double letters?
You might say, for example, that "SS" stands for "submersible ship" or "ship, submarine" or whatever ... but hold on a second--that can't be right 'cause the designators "BB" for battleship wouldn't make sense.
And it seems the Navy does NOT always double the letters -- as it does with "DD" or "DDG". The example that leaps to mind is "CVN". Why not "CCVN" (or "CCN" or "CVCVN")?
As I said, these ruminations are admittedly random and trivial--such are the places my mind wanders to when walking to and from campus!!! LOL.
Thanks in advance for any and all explanations!
