I built an entire squadron of missile boats 9kT - 8,000 speed with Magneto drive (level 4) which is pretty quick for that tech I feel - 6 size 1 launchers with reload 3 tech I think - the best I had anyway - plenty of missles - AMM fire command out to about 1mk (size limitiation thingy there didnt have a better one) and then forgot a long range scanner on all 12 of them.......
realised my error when the 20 something size 8 missiles started arriving......
I can be real good at creating space junk....
