	The lavishly equipped little ships had less combat value than their initial designation suggested. Their high speed admittedly gave them excellent response times in missions of intercepting border incursions, yet combat resilience was low in comparison with heavier destroyers. Some delightful victories were scored against pirates during the brief resurgence of [[Orion]] activity in the mid-[[2270s]], when Star Fleet’s frontier campaigns drove the slave hunters back towards inner [[UFP]] space convoys. Mistaken for meek ''Remora'' Flight II vessels, ''Chargers'' would pounce on unsuspecting raiders with the full ferocity of their namesake, the [[Centauran]] antelopoid. For example, ''USS Agriotês'' (NCC-3491) managed to render immobile two pirate vessels thrice her size while escorting colonists to the [[Kessik]] waystation in [[2278]]; the raiders promptly scuttled the wrecks before their Orion identities could be confirmed.

	[[Eckard Collins]], in turn, secured contracts for converting fifteen more ''Remoras'' into ''Charger'' subclass light destroyers, torpedo-armed sisters of the ''Remora'' Flight II design. The Mk 14 launchers that would transform the mission class of the vessels were mounted on the bows of the lateral shield generator fairings. A mechanical swiveling system made available broad forward firing angles even at the point blank ranges of convoy combat. Fifteen torpedoes were stored per launcher and medium range targeting was boosted by an all-new sensor cluster. Also new was the [[Edan]] navigational deflector. The Type H shields were retained but their secondary bubble mode was lost as the associated coils had to give way to torpedo machinery; a deflector beam added to the aft ventral hull in turn provided extra forward protection for high warp. Upper phasers were changed to [[RIM-9]] Type V units, and impulse propulsion to twin [[Scarbak]] FIF engines, whose fuel tanks were reduced in size. More than 6,000 tons of mass could be shaved off by the changes.
