It should be said that the tactical and design philosophy of "those faster than I are not as strong as I, and those stronger than I are not as fast as I" meets the actual needs. Thanks to the lofty design specifications, the "O" class large cruisers had no trouble crushing an array of sailing battleships. However, it was precisely because of these performance specs, or should we say the 30,000-ton displacement and 380mm main guns, that the design was shot down by the supreme commander. A single remark, "Blasting wooden ships with 380mm cannons? Is this the latest way to squander money?" was enough to reject the draft, and the navy felt that the three-year construction period was indeed too long. If anything unexpected happened during that time, the navy would face the predicament of having no ships available. Thus, the "O" class large cruisers were dead in the water.
