I'll second the request for a component list, since fighters take a lot more bashing to get everything to fit. One thing I will say is that I suspect you're using a single size 1 engine with a serious power modifier, but you're kind of gimping the platform by taking unnecessary crew deployment time and fuel. For a planetary defense fighter, you have to understand that you don't need 7 billion kilometers of range. That turns into about 23 round trips from Sol to Earth. You need the speed to get up to actually do something about it.
Cut deployment time to 0.1 months because it doesn't need to be out there long term. Cut the fuel to either 10,000 litres or 20,000 litres and slap on another engine.
Edit: The component list could use tonnages, as well, so we can see how the weight's split up. Just what's there doesn't really help beyond the class description.
