The C-5 Hræsvelgr (フレースヴェルグ, Furēsuverugu?) is the world's largest transport aircraft that was manufactured by the factory of the Giadian Empire Airforce and later used by the Federal Republic of Giad. Due to the fact that air supremacy is being held by the Legion, the C-5 is only flown behind the frontline.
Hræsvelgr is a jötunn in Norse mythology; he is portrayed as the eagle-shaped originator of the wind. Its designation of C-5 stands for Cargo-aircraft 5.
