use Tag against ECM.Enemies.. as a Heavy Missile Supporter you usually stay far behind frontlines, so it's ok to sacrifice some direct Firepower. Priority is to make your 40 Missiles hit! Btw i would reposition the LRM.Ammo and drop some Armor for another ton of Missiles: alternatively you could replace the LRM20s with LRM15s+A, so can up the engine and add some more Missiles!
Blagg's suggestions are good as usual and Artemis IV is definitely worth it. However, I have to disagree with the second proposal. Why should a missile boat need a speed of 90 kp/h? When going for mainly LRMs the volleys should be as massive as possible, so I'd rather keep at least one of the LRM20s. Here's a compromise:
To reposition as fast as possible, if you ever get hunted by Missile-Boat-Search&Destroyers. Of course you can run at 80kph, but if you can go faster, why not? As a Medium & Missile Boat it needs to avoid damage as good as possible imo.
