Erusean Air Force

The Federal Erusea Air Force (acronym FEAF), is the airborne arm of the Federal Republic of Erusea's military. They were responsible for much of Erusea's military dominance during the early stages of the Usean Continental War. In 2006, some of the FEAF's remnants joined with the group Free Erusea, only to be crushed by the intervention of the 118th Tactical Fighter Wing.

The FEAF's squadrons are named after colors, while their most prominent ace pilots are named after astronomists.
