The F/A-18 "Hornet" is simply one and two-seat, double engine, multi-mission fighter/attack aircraft that will operate from either aircraft providers or land bases. The F/A-18 fills a variety of functions: environment superiority, fighter escort, suppression of enemy environment defenses, reconnaissance, forward air control, close and deep environment assistance, and almost all the full time hit missions. The F/A-18 Hornet replaced the F-4 Phantom II fighter and A-7 Corsair II light attack jet, and replaced the A-6 Intruder as these aircraft had been certainly resigned through the entire 1990s.
