Babylon 5 Halik Class Frigates

Halik Class Frigates
Used as a trade escort for both military and merchant shipping lanes, the Halik is a formidable mobile defender. Able to tackle fighters and similar-sized escorts with ease, intelligent Halik captains will leave larger craft to the military vessels, knowing they cannot afford to pit their significant-but-not-overwhelming firepower with that of frontline warships. It is very capable, but has its limitations.

It was these limitations that brought about a significantly different variant that tried to bring a bit more punch to the vessel. The Haltona was fitted with some longer ranged firepower, allowing it to attack enemy fleets alongside traditional vessels such as the Avioki, giving the fleet more time to move along or jump to safety. While it tends to be successful in this aspect, its lack of overlapping firing lanes no longer completely fulfills the task for which it was first designed. Which variety gets deployed often comes down to the choice of fighting style.
