The Hornet is certainly the most modern fighter-bomber currently in service, thanks to the flexibility of its electronics it is able to operate as a fighter in the role of air superiority and at the same time can face a low-altitude night bombing mission. The F / A-18 is in service with the American Navy, the Marines and the Australian, Canadian and Spanish air forces where in a few years it has replaced the elderly F-4, A-7 and F-104.
