Here is the setup I purchased:
This is a armour buffer tank augmented with some resistance improvements but mostly centered on the two 1600mm plates and the two Trimark Armour pumps. The idea being that you can take a volley or two before the logistics ships (i.e. Guardians) can get repair cycles on you.
However, the main goal of the setup is not to survive, but to deal impressive damage while doing so. The two heat sinks and the Tech II large pulse lasers combine to deal powerful damage while the two tracking computers ensure that a target moving 1000 m/s or less transversal at 15 km can still be tracked. Switch to optimal range scripts and Scorch crystals the battleship has an optimal of 58 km with with 16 km falloff and estimated 568 damage per second.
It is a very solid ship of the line.
Emphasis on 'solid'. The align time of the vessel is the killer at almost 15 seconds from a stop. And those pulse lasers are capacitor hogs meaning it can only operate for about 3.5 minutes before the cap charges have to be consumed to keep it firing. Guardians help alleviate this of course, or triage carriers.
There are some things I'm considering changing. The Energy Discharge Elutriation rig lowers cap use of the weapons and gives another whole minute to its cap reserves which could be crucial in a combat situation, but I think would consider a Energy Collsion Accelerator for more DPS or another Trimark for more buffer. Also, the passive explosive hardener might be worth switching for an active version although that would require the use of a 1% CPU implant. Alternatively, stay with the passive mod and upgrade the cap booster to a heavy version for better ability to operate the MWD under pressure, i.e. "Burn out of the bubbles!"
All in all I'm looking forward to flying it in combat.
