The McDonnell Douglas F/A-18 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. In November 1986, the 40th anniversary of the Navy's Blue Angels, the demonstration squadron replaced its A-4 Skyhawks with F/A-18 Hornets. They saw use as a show aircraft the following season.
