Lla Vought F7U Cutlass était un chasseur à réaction et chasseur-bombardier de la marine américaine du début de la guerre froide. Il s’agissait d’un avion tailless basé sur des données aérodynamiques et des plans capturés par la société allemande Arado à la fin de la Seconde Guerre mondiale, bien que les concepteurs de Vought ont nié tout lien avec la recherche allemande à l’époque. Le F7U était le dernier avion conçu par Rex Beisel, qui était responsable du premier chasseur jamais conçu spécifiquement pour l’US Navy, le Curtiss TS-1 de 1922.

General Characteristics and Design

The Vought F7U Cutlass was a unique and radical US Navy carrier-based jet fighter of the early Cold War era. Its design was heavily influenced by German aerodynamic data obtained at the end of World War II. The Cutlass was the first American tailless production fighter and one of the first Navy jets to feature swept wings and afterburners. Its unusual configuration, featuring low aspect ratio swept wings and twin vertical fins, eliminated the traditional horizontal tailplane. Pitch and roll control were combined into surfaces called elevons (or ailevators) on the wing trailing edges. Despite its innovative design, the aircraft earned unflattering nicknames like the « Gutless Cutlass » Et « Ensign Eliminator » due to being underpowered and having a high accident rate.
