I'm not a different person, but hopefully these are in a distinctive enough style. Prussia this time, because I'd used France and the UK and Italy and wasn't happy with how horizontal tricolors looked (which ruled out Russia and unified Germany)
Steinadler jump fighter (named after an obscure aircraft in Battletech because obviously there were no aircraft before German unification; possibly suitable as a starter)
Kaiseradler jump fighter (named after another obscure aircraft in Battletech)
Geier class gunship (named for a post-unification unprotected cruiser, but it's just a bird species)
Emden class corvette (named after a post-unification cruiser that is named after a city that was at various times part of the Kingdom of Prussia; also the first on which I could actually fit a Prussian Eagle)
Prinz Adalbert class frigate (named for a Prussian ironclad named for one of the major advocates of Prussia building a navy)
Vistula class monitor (named for a river running through historical East Prussia. It is intended as a player's first experience facing the big twin turret and is deliberately a glass cannon.)
Grosser Kurfuerst class cruiser (named for a Prussian ironclad named for Friedrich Wilhelm I, an important ruler of Brandenburg-Prussia before they were formally unified as the Kingdom of Prussia)
Brandenburg class battleship (named for Brandenburg, the Hohenzollern seat in the HRE. The pulsar turrets are on autofire because of a bug in what I think is the current version of Kroom's Forge.)
There are also French, English, and Martian sets, but they all have lots of carriers or ships otherwise intended to operate together and if you answered whether it was possible to make ships show up only in fixed groups with specific escorts I missed it. Also, the Martians and French have a lot in common with the Italian set from a design perspective, though they have different silhouettes and design emphasis.
Updated Nov 25 with lore, redone shading on the fighters and Geier, an additional nose gun on the Geier, a bow gun swap on the Emden so it can actually hit anything when oscilating wildly from the railgun recoil, a redone stern on the Prinz Adalbert so it isn't so blasted slow, and additional crew crammed into the Vistula, Grosser Kurfuerst, and Brandenburg in places they had chronic shortages (they aren't entirely fixed but they were far worse yesterday), and some crew assignment adjustments on the Brandenburg so it more consistently powers the sensor arrays that are the whole point of the design.
