Interesting bow....

Most of the DLC blocks (if not all) are for decoration, I think. I'm not sure about some of the control seats and button panels, though.
desks, medical blocks, some blocks with dlc colors are the main part of the dlc items used. I didn't use dlc thrusters, wheels or conveyor-hinges etc..

are the dlc's only for decoration

Update 2021-02-17:
- added an assembler lane
- replaced 2x900mm side cannons with 3x900mm side cannons
- added gravity generator in front section (assemblers)

The mod is "DX11 Battlecannons and Turrets."
It should be listed on the right side. (It's not shown on mobile devices)

can you give a link to the big bertha gun mod? I cannot seem to find it, and I love the ship

Update 2021-02-14:
- added a weapon control room
--> one control seat for each ship cannon and one seat for all gatling turrets
--> every seat's LCD shows the ammo and damage of the assigned cannon (see screenshot)
- gravity generator is now accessable

Update 2021-02-13:
- added ~2500 blocks (mostly conveyors and LCDs/Panels)
- Added lots of signs to make navigating through the ship easier.
- Added lots of LCDs with LCD2 script (inventory, systems, etc)
- Added regular turrets for anti air defense
- connected all large canons to the conveyor system
- added escape pods (first experimental version, I will try to replace them with a pod-printer, so you will have enought pods for the whole crew.
