The EC-17U Hornet is a fictional variant of the F/A-18 Hornet aircraft family featured in Ace Combat 3: Electrosphere. The aircraft made its sole appearance in the Japanese Games Expo Demo, which featured a single UPEO-aligned unit engaged in combat over the Waiapolo Mountains. Extra additional information on this aircraft outside the demo does not exists, as the plane was not included (for reasons unknown) in the final version of the game.
