Models Please,
Good technical breakdown you referenced for us. It is highly unlikely we will have consensus on the meaning of frigate, destroyer, cruiser and battleship on this board and I accept differences of opinion on the matter. The earlest reference to frigates I am aware of is for a class of ship that was a practical warship but would never be mistaken for a man-of war. It was what you built if you needed a warship for a naval presence but couldn't seriously field a ship of the line of that day.
Destroyers of WW2 are more of what I think of when that term is used. To be sure the role and capability of a destroyer in modern terms only vaguely relates to that. They are far more than just a support ship as they once were. As we all know the era of the battleship/dreadnought is about over. Once they were the preeminent warship until the carrier took that distinction. The only other class of ship that is worthy of consideration is the nuclear powered submarine. The one thing a ship like the New Jersey can offer is survivability. It is about the only armor that might be able to survive a strike by a ship killing missile and still be mission worthy. But the short of it is... the weapons of today can defeat any armor system you can develop. So why build a capital ship like a battleship when they are so vulnerable to modern weapons systems? In a no holds barred war they would quickly fall prey to a fast attack submarine or another kind of missile.
So how does this relate to SFC terms? Let the debate rage as I wouldn't care to participate. Coming from a SFB background the similarities in terms with that of cold war era navies is unmistakable. Do we even build frigates or cruisers anymore? I'd have to do some web searches to even know. As far as Star Trek has a say in TOS terms, the constitution class cruiser was the finest the Federation built at the time and it was portrayed that way in the early revisions of Starfleet Battles. And that's a long time ago.
