The McDonnell Douglas (now Boeing) AV-8B Harrier II is a single-engine ground-attack aircraft that constitutes the second generation of the Harrier Jump Jet family, capable of vertical or short takeoff and landing (V/STOL). The aircraft is primarily employed on light attack or multi-role missions, ranging from close air support of ground troops to armed reconnaissance. The AV-8B is used by the United States Marine Corps (USMC), the Spanish Navy, and the Italian Navy. A variant of the AV-8B, the British Aerospace Harrier II, was developed for the British military, while another, the TAV-8B, is a dedicated two-seat trainer, the AV-8B Harrier II Plus is similar to the Night Attack variant, with the addition of an APG-65 radar and separate targeting pod. It is used by the USMC, Spanish Navy, and Italian Navy. Forty-six were built.
