Formulaically, the Iowas are the world's biggest battlecruisers.
You have to look at the development of battlecruisers, and the Deutschlands, in the context of their navies' constraints and the prevailing arms races.
I've covered this territory before, in context of the Fighting Ships of the Solomani and Mongoose High Guard.
Basically, the natural evolution of the battlecruiser is the fast battleship, of which the Hood could be considered an intermediate step; however, you still have to cover all the other missions that large cruisers would be tasked with, and that would be the supercruiser of which the seventeen thousand tonne Des Moines might be the epitome with nine eight inchers.
Outside of the Yamato class and whatever Hitler had planned, most navies tend to build just large enough ships to accomplish their planned missions, and even Yamatos had some logic behind them, built larger than the expected size of future American battleships, which would be constrained by the locks of the Panama canal, and by the fact that the Japanese could only build a limited number of hulls.
Our Deutschlands are likely to resemble the Azhanti High Lightnings, but with the current design ruleset, would be a minimum hundred thousand tonnes.
Why would you consider Iowa's
to be battlecruisers? Where do you draw the line between battleship and battlecruiser? Main armament? Displacement?? Armor level???
The "fast" battleship really just means a battleship that can keep up with a carrier task force (30+ knots). The nomenclature changed with the advent of carriers and the shift away from battleships ruling the waves.
The "modern" workhorses of the navies really was heavily influenced by the London Naval treaty. The major powers had agreed to ship and armament limitations, and then rumors of cheating by other navies had other navies working on 'killers' to off-set or compete with the others. The Deutschland
class was built to stay within the Versailles treaty limitations. The Admiral
(of which the Hood
was part of) class were very similar to first-line battleships, but they didn't have the armor. Comparing the Iowa
to the Hood
, the Iowa
had more armor, a heavier caliber gun and about 8,000 tons on the Hood
. Dimension wise they were about the same.
I would expect a Traveller BC to be around 100,000 tons, with BB's out displacing them by at least a 2-1 ratio. That's because Traveller ships-of-the-line tonnage is going to be based upon larger-sized dreadnoughts like the Tigress
. These ships are so massive and expensive that even the Imperium can't afford a complete fleet of them. Plus you invest a great deal of money in a single hull that you can only have in a single place. A pair of 250k Dton battleships means you can place them in two places at once, and still outmass and outgun most opponents navies.
