A couple thoughts...
Could you maybe add just a little more warhead to the Hammers, so they have WH 81 and damage 9 layers of armor, instead of WH 80 and 8 layers?
Not terribly impressed by the Drakelds... they feel short-legged and slow. They're, what, 40% accurate against your Viggens? Maybe drop to WH 16 and put more speed/range into 'em?
I don't think any ship which can shrug off those lasers is going to be scared of a measly 5 meson cannons.
No passive sensors? I suppose you don't really need them if you're locking down a chokepoint...
Yes you have valid points. The Empire have been in space for 70 years and this is the first "real" war being fought, all ships except the BB HMS Sverige is an rebuilt ship that are some 40-60 years old, upgrades have been made in weapons, power, engines, size and so on.
But fighting small units of robots are space dragons have not been a challenge...
Drakeld or "Dragonfire" is supposed to be a close proximity weapon, they were developed to be used by the first fighters but did not work as planned, the fighters were slaughtered before reaching firerange... :(So now they have been placed on a defensive doctrine. There is plans of upgrading them.
