The "Blade" is the official United Empire of EarthNavy (UEEN) designation for a standard light fighter operated by the Vanduul. In many observed raids, the Blade forms a significant portion of the Vanduul order of battle. They are commonly encountered serving as advance scouts, escort fighters for bombers, and as interceptors. Blade units acting as independent skirmisher squadrons have also been engaged. Human manufacturer Esperia has partnered with the UEEN to produce replica Blade spacecraft for aggressor training operations and for sale on the civilian market.
