1. It has been my experience that I don't spot incoming missiles until they are about 1.5m km out, so long range -R1 fire controls are not needed. Instead I use 2 fire controls: a short range -R1, and a long range R20 to R50.
2. Your missles are quite slow. It may be the best you can do at the tech level: I wouldn't want to make them shorter range, and they are already WH1, but you need to upgrade your missile and drive tech to make them more effective.
3. No long range offensive missiles? My experience is that engagements start at about 60m km. Your Molitor's will have difficulty surviving to 60K range when they can attack.
