Every planet must have them!
And not just one. Depending on the size of the planet, hundreds or even thousands might be built on larger ones, while smaller ones would still need dozens.
Adding these up, it amounts to tens of thousands of engineering projects. Calculating a standard interstellar gun battery fortress at a total mass of 50,000 tons, this adds up to billions of tons of mass.
In addition to this, there are unmanned spacecraft!
Unmanned spacecraft that are convenient, flexible, maneuverable, and can automatically form battle formations!
Unmanned spacecraft also need to rely on sheer numbers to win; their quantity must be as high as possible.
Tom divided the unmanned combat spacecraft into five levels based on different specifications.
The largest had a total mass of over 200 tons, while the smallest weighed only one or two tons.
