Now there's that one ship, you might have heard of her.
She went down exactly 75 years & a few hours ago.
Even though people knew her as a ferocious monster or a very expensive floating resort, one can say that although it failed to deliver the Imperial Japanese Navy with a decisive weapon, High Command still nailed the marketing - after all, she delivered us with a very acceptable anime series & fanboys are still drooling over her 18 inchers decades afterwards.
Ladies & gentlemen, I introduce you to Lady Yamato, in her 1945 garment (but don't worry, the proper 1942 outfit - and her sister Musashi's own configuration - will be available soon too)!
Of course, useful to war effort like a dead brick worth 70.000 tons of steel, but hey. Judging by her popularity, awesomeness is a currency better suited to our days of peace, I'd say!
