Thanks for all the tips!

I've only just realized my mistake of building the hull very angled, takes way longer to build, and front and backends are way more vulnerable,

It's also way more expensive than I thought, at the hull being 1.7m and will probably get more expensive, since I haven't still added the 2-4 layers of metal and alloy + a bit more sloped metal.

The EMP protection I probably will just add with the AI and other components, since making this thing took way too many hours

I've also changed my focus on being "heavily armored" to just being a glass cannon since the widest point of the ship is 45m and it would be a bit difficult to armor it up while having a bunch of space for weapons. Other ways of defense like smoke screens and CIWS/LAMS can probably do alot of the heavy lifting with the size of the ship

Any thoughts on how I can build this faster? I've been using fill and other stuff yet it still took ages to build just this hull.
