The frigate is likely the single most common category in civil or military use among any race and for good reason. Its size is sufficient for more advanced and larger elements as well as a useful cargo and drone storage capacity without being so large as to require special training or large crews in the case of non-Terran. Most frigates focus on flexibility and utility and arguably a frigate that doesn't and is rather duty built for arms for example is referred to as a destroyer.
The below factors are applied to component base stats e.g. with a factor of 25% a base stat of 4 would be an effective value of 1. Update to follow once ships are fully developed.
With 2 fire control modules the frigate can benefit from weapon quarters; in general the category is the smallest to support drones and coupled with moderate modification options the ships flexibility is greatly enhanced over the more specialized destroyer.
The frigate is also very simple to use and highly experienced pilots who have large reserves of concentration can equip complex modules capable of crippling enemy vessels, stabilizing damaged allies or nullifying the effects of dark weapons and more.
