In the realm of steampunk, dieselpunk, and atompunk fiction, flying aircraft carriers are a common sight, becoming a genre trope over the years. From Castle Wulfenbach in Girl Genius to the helicarriers of S.H.I.E.L.D., these behemoths of the sky have captured the imagination of many. The concept is not entirely fictional, with real-life experiments in the 1930s involving biplanes defending airships, and the Soviet Zveno project. Despite never truly materializing, the idea of a flying aircraft carrier has persisted in popular culture, with various adaptations and interpretations in comics, movies, animation, and video games.
