For all you submarine gun gurus out there (me included), I hope they model the Argonaut, Narwhal, and Nautilis Deck guns.
6"/53 mark 15 naval guns
Some highlights.
ROF: 8.5 to 10 seconds
Range: 20,670 m. Can you see that far?
Penetration: 4" at 7500 m.
Ammo per gun: 360 (thats right 720 rounds!) OMG the exploitation is mind boggeling
Anyways here is the link for complete specs on the gun.
