The McDonnell Douglas F/A-18 Hornet is a multirole fighter designed for aircraft carrier duty and is the first tactical aircraft initially designed to carry out both air-to-air and air-to-ground missions. The U.S. Marines ordered it as an F-18 fighter and the Navy as an A-18 attack aircraft. It can switch roles easily and can also be adapted for photoreconnaissance and electronic countermeasure missions. The resilient F/A-18 Hornet was the first aircraft to have carbon fiber wings and the first tactical jet fighter to use digital fly-by-wire flight controls. Variants included a two-seater, an improved fighter, a reconnaissance aircraft and a night-attack fighter. Since the first Hornet entered service in 1980, McDonnell Douglas built over 1,200.
