To study the robustness of carrier-based aircraft sortie network, the sortie network model of carrier-based aircraft was established. Two kinds of simulation systems including random malfunction and enemy attack were proposed. In view of the complexity of aircraft sortie network, the flight deck plat theory was proposed to analyze the robustness of the flight deck. Finally, the influence of the upper structure and elevator number on the robustness of network was analyzed. The result indicates that random malfunction of sortie network is robustness, while, when attacked by enemy, the sortie network is not so robustness. Sortie network is highly dependent on the upper structure, elevators and forward area of angled deck. Finally, the influence of doubleisland upper structure and elevator number on the network robustness was analyzed.
