This is my take on a Sci-Fi <insert-weapon-type-here> lol
For lack of really what to qualify it as, I've dubbed it a Gauss Rifle (similar to, but technically distinct from a Railgun).

It took a way different turn after I started it, which originally was going to be something you could outfit onto a build, but then it turned into this replica of a shoulder-fired-rifle (note: it is waaay bigger than a person). Although I still plan to knock out something that could be mounted to a vehicle, but you're more than welcome to try affixing this to something! Just be aware that I'm not totally sure how it will behave in motion on account of the helicopter rotor affixed to the front, as it took quite a bit of tweaking just to make it just sit still and not cause problems every time you fired... :}

Actual weight is roughly 15,800lbs w/o turret platform -- Turret platform was made heavy to allow it to be test fired. Oh did I forget to mention? Yes it does work! Thar be a cannon in the front that lobs 500mm shells with Impact Damage scalar set to 10, but only Explosive Damage set to 1 just to simulate kinetic impact, even though it's set to only 700m/s of velocity. Granted, I'm sure that'd be well below what a real weapons-grade Gauss would fire projectiles at, but I wanted the tracer to be easily visible.
NOTE: With Explosion set to 20, Impact at 1, and Shell @ 1000mm it has ZERO problems taking out USS Beast in a single shot when spawning at Wright -- even when it went beyond the 10 Mile cutoff of tracking. I believe I was still 1-shotting ol' Beast with it set to 5, 5, 1000. I did not try again after setting it to 1, 10, 500, so your results may differ!

CONTROLS:
Yaw Left/Right - rotates the entire platform (via a highly over-powered Gyro).
Trim Up/Down - aims gun up/down.
AG2 - Toggles Cannon (did this so that I didn't have to cycle Targeting Mode to click and move camera)
AG3 - Enables/Disables Night Vision Scope*
Throttle - [Not Necessary Nor Suggested] Revs up engines to assist in turret rotations
VTOL - Extends/Retracts Bi-Pod Arms [Not Required Mounted on Turret]
Camera 1 - View from front-mounted Camera Optics
NOTE: the "cooling fans" on the capacitor banks up front, spin by themselves, and do not require (or respond) to any inputs; that is what the 6gal of gas is for, which is more than enough for them to visually spin for 10+ minutes.

USAGE:
If spawned at Wright Field and on a system that can see the USS Beast and its two Destroyers...
Enter Orbit View and zoom out to max distance.
Enable AG2, and switch to Ground attack mode to enable the tracking system so you can momentarily see where the ships are.
Disable AG2, to rotate camera so that the ships are at the extreme-upper-right corner of the screen just barely on screen.
Re-enable AG2.
Use Yaw Right to turn platform roughly 20deg.
Use Trim Down to raise gun; only needs to be just about below the neutral mark for the proper distance to the ships.
Align the Pipper (circle targeting dot) at any of the ships.
Hold BRAKE to stabilize platform and prevent micro-wobbling (CTRL, on my system, which I'm not sure if that's default?)
Use Trim and Yaw to zero in on the ship (Beast is easier), until the Green Pipper turns Grey, indicating you're "on target".
FIRE!!
FIRE MOAR!!! :P
Make minor yaw/trim adjustments and continue firing till you blow it up! (assuming it still can at the level the damage is set to... but I'm sure it can, since I took out Tiny using rapid-fire 50cal at "Explosive 0, Impact 0" scales... yea, figure that logic out... lol)

It's not easy but it IS possible. I've taken out all 4 ships sitting at the Wright spawn point (again, granted, set to 1000mm with a lot of explosive power, but 500mm is still huge), so hitting them is possible even at distances beyond the 10 mi tracking range.
After a few minutes, USS Tiny will poke around the peninsula behind you and if nothing else, you'll be able to sink it no problem. Just ignore the "aim here" suggestion, put the Pipper on-target, slightly high and a little forward, and deliver your package!

Feel Free to Use This or Any Bits From It!

There's quite a few finer details to pick out, so it's worth looking at with Orbit Cam! Buttons, blinky lights, control dial, scope adjustment knobs, highvoltage coils, capacitor banks, glowing bits, illuminated bits, and all manner of other whatchamacallits :D Be sure to look at it at midnight as well!

** Night Vision is obviously just a visual bit of eyecandy and not actually functional; however, with high enough graphics settings to allow for Reflections (I think you have to enable "Realtime" for Plane Reflections, or at least "Static"), it DOES at least look realistic! I highly suggest changing the time to Midnight to get the full effect of toggling it on/off with AG3.

Special Thanks:

Sadboye12 for divulging their Glowing Glass Transparency Secret! Otherwise the Nightvision and battery +/- wouldn't have been possible!
edensk for answering a bunch of my Input and other technical questions in the forum!
