Here are a few for you. My guess is they'll be difficult, but you can try at least. Most of them involve floats in some way.

- Long range mine deployment submarine. Basically, make a fast, maneuverable sub, and then attach a giant pole made of floats to the front. Put mines on the end, along with depth gauges or a float tower to indicate where the mines will appear. Alternatively, if you don't have mines you could try the same thing with torpedoes on the end, essentially just giving your sub a longer attack range.

- Submerged battleship. Large submarine with float towers going up from it, so that the tops of the towers form above-water platforms to mount guns on (make sure that the guns are mounted high enough above the water that if they get hit the splash won't sink the sub).

- Submarine hunter submarine. Sub with structures made of floats extending from it, meant to be able to ram into and puncture enemy submarine hulls without taking damage to the main hull. You could also have above-water float towers attached to the aforementioned structures, with depth charges on them.

- Hoversub, as explained on the Hoversubs page on the main wiki.

- Float construction sub. Using the float construction method mentioned on the main wiki, make a large multi-hulled submarine.

- Sub with rudders for depth control. Pretty self explanatory. Not sure how you'd balance the depth controls with turning, but it should be possible at least as an experiment.

- Flying submarine. Very difficult, although I've made a successful (but not remotely practical) one before. Essentially, this is a flying ship of the sort that starts on the surface and takes off, except with upward-facing propellers mounted in arrays on the sides so that if you reverse the throttle (causing the ship to land), the momentum of the ship falling will be enough to push the propeller arrays underwater and cause them to push the ship further down and become a submarine as soon as the throttle is pushed to full again (you have to do this at the exact right time though, so that the side props are underwater and can engage to overcome the upward force of the smaller number of propellers on the base pushing upward). From there it just works like a normal sub, with the catch that you can go to neutral throttle, surface, and then go to full throttle again and become a flying ship.
