Sometimes the call goes out for specific types of battleships for specific types of situations. I've got builds ready for a lot of the situations using my favourite Rokh hull. But a recent operation required battleships with range around 30 km and capable of remote repping (armour I assume).
Since last time I worked out ship builds I didn't have access to the line of Gallente battleships so I wondered if the Megathron would be a better ship for these types of situations requiring remote repping. Here is a look at some setups I toyed around with in EFT.
Remote Repping Medium Range Rokh
Megathron with 425mm Rails
Megathron with 350mm Rails
As you can see, the Rokh performs surprisingly well as a armour tanker with rigs and the range bonus helps out to cancel the damage bonus of the Megathron (Caldari BS V versus Gallente BS IV helps too). However, if I rig a Rokh with three Trimarks it will never be any good switching back to a shield tank while the Megathron can easily move to other roles without suffering. Plus its considerably cheaper. I might have to add it to my arsenal.
The reason I included a fit with 350mm Railgun IIs is to see how much DPS I lost in order to maintain range, trading off the DPS for better tracking and the ability to fit an afterburner or MWD on there. The 425mms on the Megathron are a much tighter fit than the bigger Rokh and required a couple fitting mods which make me nervous.
EDIT: Fixed mixed up images.
