I’d like to be “that person” and complain about this.
The large majority of the entries are not battleships, which has a specific definition, and is not the same as “(large) warship”.
Under a loose definition, the age of sail “first rate” ships with the 3+ decks of guns could count as “line of battle ships”. These days it refers to the primary gun-armed, armored ships from the last century (and no, speedboat with armor and machine gun does not count). The last battleship to be constructed was HMS Vanguard for the (UK) Royal Navy just after World War 2 and the best preserved museum ships of the that type would be the Iowa-class of the US Navy.
Otherwise, please ask yourself, “is this thing on makerworld actually a battleship?”.
