You know you're not making any sense now...right?It wasn't mentioned.There is a USS Rhode Island. How do we know there isn't a USS Narragansett?
So if something isn't mentioned in Star Trek that means it can't be added at some point?
From you:
The Farragut wasn't destroyed onscreen. Therefore we do not know what happened to it. Period.
This denotes that you're of the ilk that if it doesn't happen "on screen" it doesn't happen. However, you've been presented overwhelming evidence to the contrary and now you're trying to back you shit up by using off screen "imaginary" names for ships that are never mentioned.
So which is it? On screen only, or "whatever the fuck I want"? Question mark.
