It has six fire controls, froggiest, so that's fine. As for size, I guess you use smallish ships? It's fine if the economy can support it.
Anyway, since it's an RP ship, I do not have anything to say about the weapons
However..
1) It's slow for magnetoplasma. Beam ships live by their speed, even more so if using not turreted weapons. I understand that you want to use it mostly as a missile soak, but keep in mind higher speed = higher tracking = better missile interception.
2) The annual failure rate is absurdly high. You need a LOT more engineering. More MSP would help too
3) A deployment time of two years is probably too long. Even more so with 70 days of fuel. Generalist high perfomance warships should not be in the field for more than a few months. I'd use 6 months. Keep in mind that overhaul in c# is a LOT more costly, you do not want your ships in the field for so long if you can avoid it.
The exception to this would be a fleet that HAS to be deployed for a long time, such as a jump point blockade. In that case, you need to juggle all the various needs to obtain something acceptable. Just keep in mind, it will be extremely costly to overhaul.
