re: the above Carrier Design
-You have no Direct weapon systems other than the Point Defense so the 'Combat Targeting' is unnecessary. Fighters have their own built in systems. Countermeasures is good as it helps keep the Carrier alive.
-I find Point Defense to be of questionable utility. See below
This is a Fighter at the point you can first build Carriers, using
DW Wiki Tech Trees
Tactical Interceptors
Project size 480k
Tactical Interceptor
Top Speed 135
Turn Rate 54°/sec
Shields 20
Targetting 50%
Countermeasures 86%
Weapons Damage 5
Weapons Range 200
Weapons Fire Rate 0.70 secs
Dedicated Carriers
Enable building of Carriers (when constructions size allows). Note that Carriers can be built 50% larger than current maximum ship construction size, but must dedicate 40% of their hull space to fighter bays.
This is the Point Defense Cannon you display above;
Enhanced Point Defense
Project size 480k
Improvements to Point Defense Cannon
Size 3 Static Energy Used: 0
Close-in weapons system that fires deadly bursts at enemy fighters, disabling or destroying them.

OK if we assume a 100% base chance to hit(doubt it is anywhere close to that high), plus the +10% Targeting, minus the 86% Fighter Countermeasures, would give a 76% miss rate, 24% hits.
20 improved PD Cannon shots x 24% = 4.8 Hits.
4.8 Hits at 4 damage in close, or 3 at range = 19.2(14.4) Damage
So with 20 PD Cannons every half second one Fighter will have its shields damaged, is that really worthy of 8% of your total ship size?
