The Speed King (aka Icarus or Ikaros) flight wing appears in the manga Mobile Suit Crossbone Gundam: Steel 7.
Technology & Combat Characters
Shortly after the destruction of the Crossbone Vanguard's flagship Mother Vanguard, Anaheim Electronics had scavenged the Minovsky Drive unit from the remains of the vessel and used it do design their own "wings of light" system. The Speed King was the system's testbed, and took the shape of a giant wing, controlled by a docked mobile suit. The machine was codenamed "Icarus" by SNRI, who observed the machine fall into the atmosphere of Earth during its test flight, but in reality the mobile suit with the Speed King had used its "wings of light" as a shield to protect itself during reentry.
With the loss of the F99 Record Breakers, the Crossbone Vanguard were in a dilemma on how to reach the Jupiter Sphere before the Jupiter Empire fired their colony laser. However, they would use the Speed King to reach Jupiter in less than a week, rather than months taken by a regular space vessel.
