at first glance, i was horrified to see no mention of missile/torp plastering techniques.
so here's how to do it:
drop the enemy's shields first. then, put some distance between him and you. most likely the npc will turn around and start firing at you. you do-not-fire. get your fingers on the torp launch button or missle launch wateva. as the npc gets real close, preferbably jsut below you, burn and drop the missile/torp. if you dropped a sunslayer, anything will go boooom. pretty much ends the dogfight. but if you drop a sunslayer, you-must-remember to burn out of range asap.
here's a technique i developed for sunslayers, not much different to the earlier one but:
burn, at the moment of launch, stop burning, launch, burn to the right (left, it doesn't matter, as long as you are getting away from the npc getting toasted) you'll hear the amazing metal crunching sound then, smile
as for those using starkillers, in price comparison, i'd rather stick with sunslayers. they are the best projectile in all of sirius - pretty much multi-purpose projectile. you can take out a range of fighters to transports to battleships to stations with them
oh and to he who asked about destroying bases, you can only destroy those things with a health bar on them. if they dont' have a health bar, you can't kill them.
