USS Arizona vs. Bizmark
Hello, I am new to here and this is my first ever post. I have always wondered since they were lost in their prime which one would have won or would it have been a stand off between the two if they met in the North Atlantic. Arizona has always been my favorite because I thought she never was given a chance to show her power in combat and she had just undergone a refit with a new radar system and rangefinder and It was the flagship of our battlefleet at Pearl. What are your impressions of this scenario? Thanks and hello to all of you. Kirk out!!

Welcome to the forum!!!
Interesting scenario, an old lady against a brand new BB. Bismarck´s guns are 1" greater in calibre with a correspondingly heavier shell. But Arizona has 4 more guns.
On the protection side, Arizona´s deck is only 3" thick, which is rather thin by WWII standards. That coupled with Bismarck´s 8 kt advantage in speed gives her greater chances.

Welcome to the forum Kirk, nuqneH!:
OK: The Arizona was an already obsolete ship, quite slow even for WWI and smaller. Bismarck was brand new and bigger. But let´s no talk and see both ships specifications:
I. Displacement
Bismarck: 41,700 tons standard & 50,900 tons full load
Arizona : 34,207 tons standard & 37,654 tons full load
II. Lenght, Beam & Draft
BismarcK: 251m, 36m, 10.2m
Arizona: 185.23m, 32.39m, 8.53m
III. Total Shaft Horsepower
Bismarck: 150,170 hp
Arizona: 35,081 hp
IV. Speed
Bismarck: 30.12 knots.
Arizona: 20.7 knots.
V. Total Armor
Bismarck: 17,540 tons
Arizona: 8,072 tons
VI. Main armament, range, shell weight, muzzle velocity, rate of fire
Bismarck: 8 x 15"/L47
Arizona: 12 x 14"/45 cal.
Bismarck: 38,880 yds.
Arizona: 34,000 yds.
Bismarck: 800 kg.
Arizona: 636.36 kg.
Bismarck: 2,690 ft/sec.
Arizona: 2,700 ft./sec.
Bismarck: 2.4 per minute
Arizona: 1.5 per minute
As we can check the Bismarck was not only a bigger ship with more horsepower and speed but with better armor and armament. We have to consider that Bismarck armor pattern was a lot more sophisticated and of a new Krupp steel composite. The 8 x 15"/L47 would outgun the Arizona´s 12 x 14"/45 cal. in a long range duel with deadly plunging fire and very precise fire direction. In a medium or short range combat the Bismarck´s more accurate fire direction and faster rate of fire would also seal doom for the American dreadnought.
The result is that Bismarck would emerge the winner.
I believe that Bismarck would have win even over any of the Colorado Class BBs with their 16"/45 cal. Mark V main guns. Fighting with the South Dakotas would be something a little bit different, but something that Bismarck could stand... or not?

The Bismarck, confronted by the same force but without the crippling damage at her rudder (that affected her fire direction too) and doing 20+ knots would had been a more superior foe that, very possible, could have seriously damaged or sunk one of the two: the KGV or the Rodney.
Returning to the thread let´s say that KGV and Rodney were newer and more sophisticated BBs than Arizona. In a fight against that specific American dreadnought they would certainly win.
Best regards.
Two battleships were present on 27th May sinking the Bismarck: Rodney and King George V. Only the Rodney could be considered "not new" because the KGVs were all new, not old BBs at all. KGV was one of the five sisterships the Royal Navy was comissioning those days: KGV, Prince of Wales (that fought and lost against Bismarck and had to disengage at Denmarck Straits), Howe, Anson and Duke of York. Only the HMS Vanguard was a "newer" British Battleship than those five (and extremely powerfull) sisters. The Rodney was built in 1927 (was "just" 14 years old, not a WWI veteran at all) and had 16"/45 cal. guns in three triple turrets (9 x 16"). Whatsoever the issue was that when these two BBs and supporting fleet of cruisers and destroyers engaged Bismarck, the German ship was already damaged by the Ark Royal Aicraft Carrier´s Swordfish air strike and had it´s rudder completly damaged and doing only 7 knots. But the British ships had to fire more than two thousand shells (14" + 16"+ shells from the cruisers) and torpedoes to bring the enemy defenseless.The battleships that sunk the Bizmark where older style weren't they? I was wondering what their specifications were against the Arizona or if they were of equal power? It was the Rodney and I can not think of the other. Anyway thanks for the welcome.

Couldn´t find armour scheme details on Arizona, but Ian Sturton (All the World´s Battleships) says it was armoured in the same way as Nevada. For Nevada he gives the main armoured deck (3") sited on top of the armoured belt, and below a splinter deck, 1" on the flat en 1.5" on the slopes, merged with the lower end of the belt.

Hello to all and wellcome to board Kirk .
Best regards to all
If I remember well , the "Arizona", as "Nevada", beeing a "AoN" armour scheme, hadn´t sloped armour (the only example which I remember of such thing like a "AoN" with slopes is the "Richelieu"), but I can´t assure this.Did Arizona have a sloped armour deck behind her main belt?
Best regards to all
