hello Krummja,
A, couple of general observations. Your ships need more armor. Especially your beam ship. I think one of the other posters recommened 8 levels and that is good advice. Your AMM doesn't have a warhead, it will only work if it has a warhead.
8000 km/s if much faster than my fleet speed at your engine tech. That isn't necessarily a problem but each design choice you make has consequences. The more engine speed you have, the less space you have to dedicate to weapons, sensors and armor.
With that said, I'd make the beam shp faster. I usually aim for 10000 km/s for my beam ships.
If you are going to depend on aam for missle defense, you should improve your missle reload speed. You would benefit from having a 5 second reload rate for your size 1 launchers.
Otherwise a pretty good first set of ships.
