Ok, I have read on the forums where some people have a bonus defense of 80% on their ship when they are moving. How do you get it that high?!?!?!?!?? My normal bonus defense is 70%, and with the Aegis engines, I can get it up to 75%, but how do you guys get it up to 80%?!?!?!?!?!?!? Oh, by the way, I fly the Defiant-R, (Tactical Escort Retrofit)
Maximize your Defense by having your Engine Power around 65 (actual values very due to efficiency), this will get your Defense up to 70%.
Two Aegis components add another 5% each (Total of 10% Defense), which makes it 80%.
Then also factor in the Evasive Trait that adds another 10% Defense. Which gives you a maximum Defensive Boost of 90%, without defensive boosts like Evasive, Deuterium, or the Subspace Console (from the Devidian series).
