im a noob more or less but i think try not to use the missile turrets in the normal way (green status in the lower right window), you can use Q key to launch missiles aswell and depends on the target (for example cap ships), you may not use that (they drain energy too), so you have more energy for light mortars and so on (cap ship weps).
for my limited exp 1 inferno gun only can fire 6 shoots before depleting the energy bar (BH destroyer and huntress and i think most destroyers and normal cruisers too), a light mortar 3 shoots.
right now i have 1 light mortar 1 inferno 2 cerberus 2 nomad and 2 missile turrets in my BH destroyer, using in green status cerberus and nomad guns (and miss with the Q).
and more or less works fine, of course depends on the firing arcs of each destroyer/cruiser.

that weapon array is mostly anti cap dont you have problems with fighters or bombers?
