The original Dralthi entered service in 2521, a century before first contact between the Empire and Earth. These tiny medium fighters lacked the distinctive gull or bat wings of their descendants, featuring pointed, knife-like projections instead. KF-100s served with distinction in dozens of inter-clan conflicts as well as in wars against the Wu, Varni and Mantu. These Dralthi continued to serve well into the war against the Terran Confederation, playing a role in every major naval engagement for the first twenty years of the war.
