A rear-view of a Stiletto near planet Norion.
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.
Samus' Gunship alongside a Stiletto-Class Fighter.
They bear some resemblance to Samus's ship in Metroid Fusion, possibly because that ship was built using Federation technology.
