Took me a bit to remember this bit, but here ya go.
Iowa-Class Battleships, specifically the Guided Missile refit.
At that point, they DID have their primary weapon.
(and the turrets were superflous so long as missiles were still available. 23.some Nautical miles is great and all, except the missiles go father, are more accurate, and generally get there faster.)
On the other claw, please, show me a wet-navy ship with a Spinal-mounted weapon.
I don't know of any, except in other videogames.
Most StarMade vessels are either built around, or rather prominently feature a Spinal-mounted weapon.
Oh, and StarMade even has that nifty little "shot-cone" in which your pointer (and resulting shot) can deviate an indredible 30 degrees off-axis.
So, I think my point is still valid.
Though that was an amusing comeback, NTIMESc. 'Bout killed myself laughing so hard.
