The Tralthi class started as a Fralthi inspired attempt at a light cruiser, but the design team ended up with a fast frigate instead. The Fralthi class engines allowed this frigate to operate effectively as a commerce/convoy raider, and to act as a picket ship for fleet operations. In addition to the Fralthi engines, the Tralthi also retained the light fighter capability of the Fralthi class cruiser. Which proved beneficial as a recon/screen element when conducting raiding operations.
