Again, the vessel had 12 cannons in the main turrets. 2 placements forward, two barrels per placement - 1 placement between the superstructure and the funnel, 2 barrels, 1 placement between the aft tower and the funnel, 2 barrels, and 2 placements on the stern, totalling in 4 barrels. This adds up to 12 barrels in the main battery, which were 36 cm - 14.4 inches approximately.
Her secondary artillary battery, placed in the hull just below the weather deck and in the armor belt, in the secion added to the hull in her first major refit, she weilded 16, single barrel 15cm (about 7 inch) cannons. Which, after 1938 was converted to 14 15cm cannons.
She then also bore 8 12.7 cm gun with an additional 16 13.2mm guns (quad mount).
So . . . Need I say more?
Her artillary was slightly less than that of the Bismark in bore and shell size. However, due to her increaded number of placements, her reload rate weas remarkably fast and she had the ability to take on a multiple targets, quite easily. As a matter of fact, these ships were developed with a new, "caged" strategy in mind.
The vessel had a substainal armor belt, especially after her major refit in '41. I have do doubt in my mind she could give the Bismark a serious run for her money.
Also, as a testiment to the awesome construction of the ship - after Fuso was attacked and the battle of Surigao Strait, she had exploded in half. The two halves were so well made, that after burning for hours, and of course being open to the ocean, the two halves stayed afloat for two days before they sank.
Now tell me that is not some incredible design work.
I have the anatomy of the ship and a set of plans. I have studied the IJN ships and their design for several years. I have also written a paper on Japanese naval warfare strategy and vessel design. I would think I know what I am talking about.
