[Strategia_In_Ultima]

Try to completely kill off the heretic enemy ASAP. (or at least cripple them beyond any hopes of quick repair) When that is done, you can refit your ships and remove the ECM/Scattering/Stealth armor and place normal/emissive armor on it, and more weapons.

You could also try to build several shield ships in your fleet, if the enemy concentrates on them first it'll be even longer until they can fire on your ships. This is espeically handy if they use a lot of weapons with a ROF of 2 or more.
