Oh way cool

Thank you.

ever hear of a program named Space Engineers?

Sadly, no.

its a sandbox builder on STEAM, though the twist is you are building spaceships of various sizes.

Ok.

Think Minecraft In Space.

An interesting (and prominent) deployment of the saucer's running/formation lights...

Thank you.

Fast Interceptor Actually Isnt A Class Naming Convention. To My Knowledge
If The Ship Existed, It Wouldnt Be A Fast Interceptor, But Perhaps, A Galaxy Class, Orion Class, Etc. I Do Believe.
Fast Interceptor Isnt Really Completely Accurate. YET. It Is An EPIC Writeup. And, An Absolutely Amazing, And Astounding Job Of A Ship Illustration Of A Ship Schematic!
The Symmetry Is So Wonderfully Accurate!
I Really Think This Is Amazing!

Ship Classes Are Usually Named After The First Ship Of That Class. The Firs Ship Of THe Excelsior Class, Is Named The Excelsior. (for example)

Cool looking ship!
