Thought it might be worth uploading all of my subs, primarily because I modify them frequently and, when joining other servers that have the subs, they tend to all be horrendously outdated.

So yeah, here's the a picture of all the subs (as of like, 3 months ago) put together in paint so that you may compare the sizes:
(Really low definition btw)

Without further adieu, from smallest to largest;

SS Scylla - Miniature sub. Decommissioned
Made this in literally ten minutes. I plan to attach it to a bigger submarine as an assault vessel, but until then it serves a small two-person submarine. My 10th submarine.

SS Maia - Non-Nuclear submarine.
This is a pretty mundane submarine, nothing special about the outside; The only interesting thing about it is the Battery Core, which allows for fine manipulation of things such as the output level of the battery arrays. It is pretty much a test submarine for that feature, but nevertheless it works well and I like it enough to keep it in rotation. My 9th submarine.

SS Rhea - Unique Design
Made entirely with unique design in mind. I wanted something nice and open with more of a vertical approach, and in that front I succeeded. It's a little under-armed, and despite being rather small the openness of the centre gives the impression of it being large, and so when playing it with low pop people seem to complain it's too large. My 3rd submarine.

SS Moros - Unique Design Decommissioned
Another non-generic generic submarine with much the same purpose. This one plays with how corridors and stairs work, with nothing being 'levelled' as it should be. A little hard to navigate considering the (intentional) seperation between the front and back half by the (another unique feature) central ballast, but it does well on the fighting part, providing the players can manage to keep the guns loaded. My 8th submarine.

SS Hades - Nehalennia Esque Decommissioned
As you can probably see from the picture, this is modeled off of the Nehalennia with the idea of high visibility. The corridors are made of glass, aswell as the ballasts. As this is my 2nd sub, I had yet to discover the subtle nuances of Barotrauma and so things like wiring a little ugly in places and reactor flooding is a big problem. I rarely play this one, simply because of the lack of weaponry. It was considered O.K before subs with more than just front guns started emerging, but after that...

Luxury Liner - Roleplay vessel.
Roleplay vessel, simple as that. It's somewhat resilient in terms of combat, but it's firepower is severely lacking, and so I don't recommend use on standard missions.

SS Odyssey - 'proper' submarine.
My personal favourite. Made after the Mk II, and Mk X, it too was made to be tanky. The sections again separate themselves when one becomes flooded, however in this submarine the flood doors can be overrided. Much like the Mk II, it has a maintenance shaft connecting the sections together. This submarine's sections are also entirely independent if the 'grid' junction boxes are disconnected. All sections have 6 pumps and batteries. It also provides a large amount of information (while avoiding the oh-so-common unnecessary habit of including things like oxygen levels which serve virtually no purpose as there's absolutely nothing you can do with that information aside from realising that you really should get power back on) such as a battle stations button, compacted water leak warnings, reactor heat indicators, medivac requests, alert levels, etc. Another neat feature which most people seem to overlook is placing windows where the guns can fire, as fish have a tendency to aim for the windows. My 7th submarine.

SS Odyssey Mk II - A tank in sub form.
A tank in sub form sums it up perfectly. It's made to be resilient, that was my only purpose behind it. I've never, ever seen it entirely flooded. The sections separate from eachother when one becomes flooded, each with it's own automatic bilge pump and ballast. Every section is on a separate grid from the reactor, and so will not suffer in the case of a reactor overload (unless engineers leave the breaker switches on) it also has a maintenance shaft at the bottom, connecting the sections when they are separated by flood doors while also acting as a second hull. Due to the sheer size of the submarine, it's virtually impossible to sink the submarine with any less than 3 leaks. (Unless the power is off). My 5th submarine.

SS Osirus - Another mobile battery box. Decommissioned
Title says it all. It's a mobile battery box, just like the Maia. https://www.dropbox.com/s/maheuoyb3n7d2 ... s.sub?dl=0

SS Atlas - A light attack shuttle. Made to accompany the SS Odyssey, however should fit onto any other submarine without any problem. Intentionally has hard to reload cannons and low battery life so that it has to return to the Odyssey frequently.
https://www.dropbox.com/s/bz1nu75ttktyz ... s.sub?dl=0

SS Atilla - A docking-only respawn shuttle.
Designed more for anti-grief than any other reason. Hatch can only be opened once docked, has two hatches to make any hack attempts noticeable. Has a captains quarters style thing with all the controls and a door lock, so that if the shuttle rams into the main sub you can usually blame the person who was sitting in there rather than just guessing. Diving suits locked away in the back, captain opens it. Comes with basic repair gear in the locker, 4x masks, 8x oxygen tanks, 4x welding tools, 4x welding fuel tanks, 4x flashlights, 4x batteries.

Escape Shutle A real simple, small escape shuttle. Only has an undock button, as it's not meant to return. Batteries come uncharged, meaning the shuttle needs to be prepared before launch. There's also a flipped version for attaching to the rear of a sub.

Battery Core - Submarine part.Here's my 'battery core', used in a few of my subs. Decommissioned

Here's a picture of how to correctly set it up (the picture is set for 5kw output) The maximum output is 8kw, but if you're using this you should probably also have a system for saving power by turning off rooms when not in use, which should be able to save atleast 2kw in a 10kw submarine, so it should be able to power a sub the same size as a single reactor can do.

There are two output junctions; The one in the middle of the room is the main output, connect that to the rest of your submarine. The other is the tertiary junction, located behind the super capacitor in the bottom left corner. Connect to that to high-powered devices such as engines and guns. (I suggest adding a duo-bypass for the engines so they can use either grid, however.)

The wifi signals used are 2-22, and multiples of 5 up to 60. (So 25, 30, 35, ... 60) Be sure not to overlap.

Use channel 13 to toggle the lock on adv. power control room, use 17 to remotely activate secondary (left) battery array, 16 for the primary battery array, and if you want to you can send a signal to multiples of 5 to set that as the desired output. (Channels > 30 are the secondary array. E.G sending a signal to 20 will turn on 4 batteries on the primary array. Sending a signal to 55 will turn on 5 batteries on the secondary array.)

Try to avoid using other batteries in conjunction with this system. (If their power_out connects to something that isn't the main grid, that's fine.)

I've tried to avoid generic-purpose subs. All the subs had a distinct design goal in mind before making them (aside from the Rhea) and all of them are somewhat aesthetically pleasing, or atleast they're not floating boxes and all have something that passes for organised wiring. There's also 2 subs not included; My first sub (the SS Titan) which although I personally liked, the main hallway was a T shape with a single, long ladder that people got rather frustrated at when they got knocked off. Also my fourth sub, the first variant of the SS Odyssey, which simply does not compare to the other two and so was deemed a failed project and scrapped.
