I've been working on a new ship in creative mode, a small destroyer. This is a design more akin to The Expanse, utilizing architecture that's practical to implement in Space Engineers. Here are some pictures:
I experimented with different armaments, and I decided to make this a gunboat rather than a missile boat. Bullets are way cheaper than missiles in survival mode, more accurate, and less destructive - a good thing when you want to actually disable and salvage a ship. I've got enough firepower to tear up critical systems, and enough armor to take a good pounding without losing my own key systems. The smaller turrets are dedicated to point defense, to help thin out any incoming missiles. Speaking of missiles, I do have a single battery of fixed rockets,
You'll note that these are protected by a "gun port", which actually works surprisingly well. Enemy turrets seem to target this missile launcher first, so I tend to launch my missiles at long range as I'm making my attack run, then I close the door (which is surprisingly tough) and proceed to orbit the enemy, keeping my topside to them, which allows all 9 large MCs to fire. The top and nose of my destroyer is heavily armored, with a much softer "belly" that I keep away the enemy through good piloting. I've gone against some tough NPCs, and this ship can take a severe beating and keep on ticking.
Unlike my other ships, the bridge of this ship is buried deep inside the destroyer, relying on cameras instead of windows for viewing the world.
Only the bare essentials in this ship, no luxuries! I also kept things simpler by not attempting to connect
everything via conduit. For example, the forward section houses my torpedo launcher (I'm a Navy guy) and regenerative hull system. It has its own cargo bays for holding ammo and repair components. I opted not to connect this to the main conveyor system in order to have a more open and ascetically pleasing bridge, which means manual loading, but that's fine, it gives me something to do with these "space legs".
This ships is bare-bones in many ways - no FTL, no built-in repair projector, only one H2 tank, limited maneuvering thrusters, etc. It's definitely not a perfect ship, but I'm okay with this. I actually prefer having a selection of imperfect ships than trying to build the one "Superman" ship. And at under 7K PCU, it's a bit of a disposable ship, something I won't be afraid to take into battle against NPC and PvP foes alike.
I'm not sure when I'll start building this on a live server. There's really not a lot of PvP happening on CA1 and 2, so I may save this for a PvE server should I ever find one I like.
