Well, writing a nice post dealing with a comparison betwween KM & USN battleships may be a good idea - though IMHO there are few pairs of navies that are less comparable.Only just a comparison & getting some ideas between the H-Class battleships & the US battleships as to appearance & historical background etc. etc.
However, to be meaningful, it requires far more than posting one picture.
You first want to compare the most evident features like sizes, gun numbers & calibers, speed... Then you may have a look at more complex but still basic features, like armor (complex because layout is as important as thickness), endurance, firecontrol, cost.
Then you may enter global synthetic features, like survivability - which requires assumption regarding the kind of damage and hence involve a study of the doctrine of the navy considered to understand what kind of enemy and under which circumstances the ship is supposed to fight.
There are many other features, bu in the end you'll have a list of features with values (or assessement) to compare. (Note that some features may be blank for one ship and not for the other.)
Hence you'll be able to make assessment
"Battleship A is better than battleship B regarding feature X" - but even a simple sentence like that is already the conclusion of a study as soon as the "feature" is more complex than size or # of guns.
But then, even if you're able to have a comaprison for each feature, you're still a long way from a global comparison.
You then have to check how these features are inter-related - having bigger guns and heavier armor is not sufficient to be the best, balance of the design has virues of its own.
And then you have to go back to the doctrine of each Navy, to understand the role of the ship under investigation - a 'medium' ship which fits perfectly the doctrinal needs of its Navy may well be in the end better than a 'super-ship' unrelated to any doctrine (and here H-class is a nice illustration)
So, yes, comparisons are interesting but such a complex work cannot be summarized in one picture.
KMS AufwändigI wonder what potential names for the H-class ships would've been?
(sorry, couldn't resist ...)
