This is my first boat, so be nice please ;)
This is my take on the Zumwalt class destroyer, with a few added bonuses here and there. Most of the weapons are already exposed, but that doesn't mean this is not still packing a good bit of firepower underneath! This uses missile bays (28 ATG missiles) and a hidden rocket launcher for those times when guns just don't cut it. I made the rocket launcher to resemble the one on the destroyer from "Cars 2" xD

Notes: I took a more simplistic approach with this one and kept the part count low, so it should be mobile friendly.

Weapons and controls-
* Vtol- always used to rotate given weapon
* Trim- always used to raise and lower given weapon
AG 1 and 2- Two main guns
AG 3 and 4- Hidden rocket launcher. AG 3 with trim and vtol up to open doors and and AG 4 to activate launcher.
Note: Lower the rear guns first before firing anything
AG 5- rear machine guns
AG 7 + Vtol - Open missile bay doors *Do not fire missiles without opening doors first!!!*
AG 8- moves around the cockpit using vtol and trim to make locking onto targets easier
