This mod is genuinely great, as it's one of the only ones I've found that are both compatible with 0.14.3, have very large roof turrets, and said-roof turrets fire like cannons. I've been wanting to build a Spaceship Yamato and this mod is exactly what allowed me to do that. It's not perfect, as the style of the Heavy Macro doesn't exactly fit the Battleship exactly, but it works and it's fine with me.
To me, this is just the next best thing after the Naval Artillery mod got discontinued. There really should be more mods like that. Roof turrets are slightly underappreciated.
