Re: Enterprise Blu-Ray - Fix the Klingon Battlecrusier!
I'll suggest that the Klingons aren't really using 200 year old ships, but merely sticking with a general design that works for them.
A diesel submarine from 50 years ago is fairly similar in appearance to a nuclear submarine today, at least in outward appearance. Yet we know that propulsion and weapons and systems are vastly different.
And a 50 year old aircraft carrier, say USS Midway, is again generally similar in appearance to a modern day nuclear carrier like USS Reagan.
And the exterior of the Volkswagen Beetle was virtually the same for over 60 years.
