The Harrier GR9A resulted from a collaborative partnership between McDonnell Douglas and British Aerospace to produce a second-generation Harrier based on the McDonnell Douglas AV-8B.
This incorporated an advanced wing design, improved avionics and increased bomb and missile-carrying capacity. RAF variants started as the Harrier GR5, and were later upgraded as the GR7 and GR9. The RAF used them for attack and close air support duties in conflicts such as Kosovo, Iraq, and Afghanistan.
