The F-3 is a maneuverable strike fighter developed by Lucasa Aerospace with the lessons learned from the failed PT-F-2 project being put into consideration. The F-3 is the first fighter of the Lendrian Air Service to use the EXTASY (External Targeting System) Targeting Pod, making it possible to strike targets without directly going through the targets.
