It's very myopic. Won't be able to see targets until they are almost on top of it.
Yeah, the range is
really short.
Maintenance is. . . lots. Could probably cut that in half.
Maybe it's for repairs too? I seem to remember repairs costing Maintenance Supplies, and lots of it.
Got a crapton of fuel too.
Indeed. You'd usually see that amount on a scout, not a warship.
More problems are: Your AMM have to use the same launchers as your ASM. This is very bad since the RoF is 70s between each volley, meaning your AMM defense is horrid at best unless your missiles are extremely accurate.
Another problem is that your ASM uses a size 10 warhead. That's not an optimum size for breaking armor. Optimum sizes are square numbers. With 10 damage 1 damage will go to waste against armor. Sure, it's kinda good when you break through armor, but if you've broken through armor 1 point of damage won't really matter a whole lot.
Some shields would do your ship good, because with only armor your ship will get armor damage even on the weakest attacks. That means you'll sustain permanent damage until you repair the ship at a shipyard. Not good in a war of attrition.
