The Gladius is a long-serving military light fighter spacecraft developed by Aegis Dynamics and first utilized by the United Empire of Earth Navy (UEEN) in the 26th century. Its frame is easily modified, and has undergone numerous technology retrofits in the past three centuries. The Gladius has served extensively along multiple fronts and has logged thousands of combat missions. In recent years, squadrons have begun to phase out the Gladius and convert to newer craft like the Anvil Arrow. As this conversion continues, surplus Gladius have become available on the civilian market.
