Just going to point this out here:
With the newest patch adding auxiliary power, cloaking larger ships has become possible.
I am in the process of building a fully cloaked and jammed ship with full weapons, shields, power, thrust - all the goodies with a mass of around 200k. The challenge, however, is in the massive amount of calculations you will need to do. This is a high risk/high reward method.
If you do not accurately calculate out the mass of all of your systems beforehand, you will miss your power mark and waste a lot of time. Additionally (hint), the ratio of auxiliary power blocks at max efficiency will balance the amount of power and shields you can store versus the volume you have available to build with. In order to obtain all the systems I wanted with 1.5 mil shields, 50k regen, and 100mil power cap, I had to calculate out the volume of blocks I would need, and scale up my hull to fit that (yet another hint).
By no means am I saying this is easy; this process is very long, very easy to mess up, and the ship you build will be seriously specialized in its combat capabilities. But the challenge is its own reward in my opinion.
The hull I've been working with :D:
My Two Cents:
I would ask that anyone willing to go through this process not post a final version of their ship for download. Images and tutorials are always more than welcome, but this is a lot of leg work and it would be neither right nor responsible to unleash a finished product for download in Starmade's current progress state. Perhaps in the future, after the cloaking/jamming/scanning overhaul.
Good luck,
Falcon One
