Carriers: The British carriers win in this category. They were very well armored, to the point that Invincible even lived up to its name while operating in the Med.

Eh, this I'd disagree with. British CVs were at best adequate, I tend to wonder why they tended to flood so easily after 1 torpedo hit. >20,000 ton vessels should be able to withstand at least a torpedo or two. They lacked emergency power systems, lacked decent airgroup sizes and tended to be rather bad at turning. Only until the end of the war did they start putting decent CV designs on the table (Malta). That all said, they did look nice for the most part.

The Shimakaze was probably too big to be useful. I'd nominate the Akitsukis instead.

Shimakaze > Akitsuki in tonnage?

2567 vs 2701

Shimakaze wasn't all that big, the issue with it perhaps was the role it fulfilled was not going to be used by Japan against the US. It wasn't the right DD for Japan at the time, another Akitsuki would have been more useful.

I dunno, Ryujo was about as durable as any other Japanese CVL, it had a large hangar, decent range and 29 kt speed...I'd say it was a success for what it was.

Cruisers: Gonna give this category to the Brooklyn CLs. 15 6" guns are just plain scary. And at least one of the class was still in active service in the early 1980s.
...

I won't add to the rest, but as for the Brooklyns';
They not only carried class A armor (better quality and thicker in the vitals than other nations' CA 'treaty cruisers...including Japans'), their 6" L47's were very long range and fired very heavy shells (for 6") and very fast firing (her fifteen gun battery could fire at a 'minimum' of 120 rounds per minute - 8 to 10 rounds per tube, per minute).
Combined with effective advanced fire control arrangements, RADAR ...and some experience by crewman ...they were just devastating to surface ships within 20,000 yards.
That is why the US Navy sought only Brooklyn/St.Louis/Cleveland class CLs for night engagements after Guadalcanal.
A good example was Montpelier (granted - a Cleveland) fired over 1,800 rounds of 6/47" & 5/38" in only 15 minutes at the first battle of Kula Gulf in early '43...and then went on later that night to fire over 700 rds of 6" during the nights planned bombardment.

Anyway, national-pride-be-damned, the Brooklyn's were excellent ships for their day.

EDIT: Not to mention the Savannah single handedly turning away the Herman Goering Panzer Division in the Gulf of Gela at Sicily in 1943...

I agree. Do not forget the effect Brooklyn had on the other designs being touted (Cleveland and Baltimore). It has to be the best design. The evidence is enormous to support this.

I'm surprised no-one has mentioned Liberty ships. Without the supporting echelons armies are only so many ill-fed men without bullets after no more than 4 or 5 days of combat ( often less ).

I would suggest that if design means most potent ship for its weight then obviously one would have to go for one of the smaller ships, if one includes survivability in one's assay then probably a CA or BB would take the title but if "best designed" is taken to mean which ship most efficiently meets its design requirements and got something useful done ( after all a ship could very efficiently meet its design requirement to be the best anti-rowboat CA in the fleet but that CA is unlikely to be useful in a fleet action.


If we're limiting it to warships then the best-designed pound for pound is going to have to be the late-war schnellbooten. Excellent armament and seaworthiness ( for their size ) and fairly good survivability make them superior to the PTs ( although the PTs WERE very well-designed for the environment in which they worked - which featured dashes from cover and rewarded manoeuvrability and small size more than the situation in the Channel did ).

If you aren't going pound for pound and are going to include larger vessels albeit with the understanding that one cannot outrule a ship simply because it couldn't defeat a ship twice its size in battle then I'd have to go for the US CLs with the 15 x 6 inch guns. Their rate of fire and multiple turrets let them simply rape any IJN DD, CL and even most of the CAs. Their guns had long range and by filling the air with enough 6 inch shells ( up to 120 per minute IIRC ) you were guaranteed to get some hits at what you were aiming at fairly rapidly ( and those hits were likely to be very devastating ). Certainly when matched up against RN and IJN CLs those USN CLs with the 15 x 6 inch guns ( I can't remember the class name right now ) tend to reign supreme given the twin advantages of more guns and superior armour +/- radar when facing IJN CLs

Given that the Clevelands were the follow-on class, had one less turret, and were regarded by the Navy as overloaded makes me wonder whether the Brooklyns were really that good.

I've read that the Bismarck was able to steer without it's rudder - but only as long as it was not turned in more than 15 or 20°.
As the Bismarck was hit when it tried to evade torpedoes, the rudder was turned in more - and that caused the problems!

Of course it was able to steer with it's engines!

Eek! The Didos were a poor design, top-heavy and poorly subdivided, showing great eagerness to capsize. And for "AA" cruisers, they were lousy against aircraft.

A reasonably well-informed "IF" shows that Iowa had the armor and armament to easily best Bismarck, since the latter couldn't penetrate an Iowa. And this says nothing about the inferior secondary armament and fire control on Bismarck.

Bismarck sunk pride of RN in five minutes and criple next pride of RN in one battle.

Bismarck sank a woefully undearmored battlecruiser with a lucky hit in five minutes, and just barely escaped from a British battleship even though the latter was deployed before her guns had been productively worked up. If KGV had been there, or even old Rodney, rather than Prince of Wales, Bismarck would have been sunk shortly after Hood went down.

In Re: Type XXI - see Clay Blair's book Hitler's U-Boat War - The Hunted 1942-1945 (Blair has been accused of being way over the top in being pro-U-boat, so if anything he is tends to be too forgiving of their faults)

I think you have that backwards [;)]. Blair was accused of being way over the top in terms of being anti-Uboat. His rather negative accessment from visiting the captured Type XXI at the end of the war and his mentioning of his service's acomplishments in the forward of Volume one didn't help matters, nor his continual and chronic use of negative adjetives when describing specific German uboat types within the text of his volumes.

True enough, but they were not particularly well-designed ships: notably, they tended to break in half without warning (and sink)... after several occurrences of this, the design was reinforced, but they continued to have serious problems with structural cracks threatening catastrophic failure.

I believe it's already been pointed out that Bismarck first revealed her inadequacy at steering by engines on her trials. Her captain specifically mentioned it. However, I can't see it as a major flaw. We would not even mention it if not for that single torpedo hit. The fact is that Bismarck's steering gear protection was quite good by European standards--but that involves only armor, not intended to defeat torpedoes. Just for fun, I'll note a couple other incidents that might be instructive. Marblehead had her rudder jammed, but she was able to stear by engines. Intrepid had her rudder jammed and found herself steaming inexorably toward the enemy; she escaped when her crew fashioned a sail that counteracted the rudder. Vittorio Veneto survived a torpedo hit to her stern; she had three rudders.

Out of curiosity, what do you make of the claims that Bismarck could have "backed" into port*?

*I.e. - after the torpedo hit, she had weathercocked into the wind, and was moving directly away from port and towards the enemy. One group of naval officers has claimed had she been put into backing astern , she would have moved in the (generally) correct direction and probably would have been able to escape her pursuers.

That's what modular construction and rushed designs does for you. The Liberty ships were a crucial part of winning the war for the Allies, but a good design they certainly weren't.

Bismarck was a very flawed design, in image below you can compare the proppeller/rudder arrangement of Bismarck vs Littorio,Vittorio Veneto Class and reach the conclusion in what ship one single hit can have disastrous consequences. Bismark had the 3 propellers in almost same place and didnt had secundary rudders.

ORIGINAL: Nikademus

any ship that takes a hit in the rear is going to have serious difficulties. Have to agree with Tiornu in that I don't see Bismarck's props/Steering gear as a serious design flaw. KVG rear area wasn't weakly designed and one torpedo created a havoc that directly led to the ship's demise. Protection of the "ends" was one of the great problems that battleship designers were never able to fully solve in the age of aviation. One reason they became eclipsed.

True - but wouldn't a truly great design have attempted to rectify the problem with the Achilles heel? Since we are discussing "best designed" ship, i'd expect better attention to a serious potential problem.

Thats the point....I don't believe it was possible to rectify it to any serious degree. Secondary rudders sound great but didn't prove to work very well if the main rudder went out or worse, was jammed. Four screws, well seperated is no gurantee. PoW suffered damage to both her facing props from the one torp hit due to the amplified shock effect of the close blast underwater. TDS systems can't get the width to make any meaningful contribution in those areas. Would another class, in those Atlantic swells have preformed any better under similar conditions..and enough to escape two pursuing and fully intact BB's?
