Not sure how "re-imaged" they are until we see under their helmets. After all, the whole point of the helmets was to keep it ambiguous whether their foreheads were smooth or had the ridges of TMP and beyond.
That might make it more tolerable. Might. Those helmets look really.... stupid...
as a warrior race armor makes sense, even if they are now spacegoing they would retain some semblance of armor for purposes of tradition as much as anything.
Particularly if they play up the more agressive nature where subordinates get promotion by killing their superior etc.
As for ships etc being named after each other - remember Raptor is most likely a federation assigned name for the family style of craft, same as Bird of Prey. I wish they had thought to give this a true klingon class name in ENT when it appeared.
OP, ST VI was comparing the Klingons to the communists...hense the whole conversation with Hamlet in "Original Klingon;" commi's back then were just taking known stuff and taking credit.
The TOS Klingons were very much patterned after the old Soviet Union. In later portrayals a certain Nazism did creep in... but let's be honest. The difference between radical National Socialism and Soviet style Communism amounts to hairsplitting at best...
ZOE: "Sir! You paid money for this?... on purpose??"
KIRK: "Excuse me... what does God need with a starship?"
Yeah there's that too. They've been trading names back and forth for a long time; a lot of Star Trek ships have been named after real ones... or they at least share a name even if it was unintentional.
Also, the US Navy has had a ship named Enterprise it's entire history. I have a suspicion that the US will never not have a ship named Enterprise. If we built an FTL ship tomorrow, I would wager that it would be named Enterprise.
