In un-moded SS small LRM may be inappropriate (not sure, me playing without mods was long ago and not for long), but after installing some mods you will find that small LRM's are quite common addition. And most such missiles have better stats, compared to this one (at least enemies can hit them without having to put to much effort).
As for publishing in separate tread - may do a pack of ships and weapons, but some are ported from old mods and i have to find someone to give me permission. Won't spam with single weapon treads however.
