The Stiletto-class Fighter is the basic air and space fighter of the Federation Fleet. Stiletto Fighters can be seen hovering near the G.F.S. Olympus towards the beginning of Metroid Prime 3: Corruption.
Later in the game, damaged Stiletto Fighters can be seen on the wreckage of the G.F.S. Valhalla. The first time Samus sees a Stiletto Fighter in action is on the initial Galactic Federation invasion on the Space Pirate Homeworld. They are transported throughout larger vessels on a system of converyor belts, and launched from them in the docking bays.
They bear some resemblance to Samus's ship in Metroid Fusion, possibly because that ship was built using Federation technology.
