The future of air combat lies not in singular “game-changing” technologies like drones or AI, but in integrated, multi-domain systems like the Global Combat Air Programme (GCAP). This sixth-generation fighter, a tripartite venture between the UK, Italy, and Japan, emphasizes networked warfare, advanced sensors, and adaptable design to counter peer adversaries. However, its success is far from guaranteed. The program must overcome the defense industry’s historical challenges with procurement, cost overruns, and delays to deliver a truly revolutionary capability by its 2035 target, ensuring it doesn’t become another high-tech, low-impact “battleship” of the skies.
