In January 2007, the Harrier GR9 began its first operational deployment at Kandahar, as part of the NATO International Security Assistance Force (ISAF); Harrier GR7s would be progressively withdrawn in favour of the newer Harrier GR9.[74] Following five years of continuous operations in Afghanistan, the last of Britain's Harriers were withdrawn from the Afghan theatre in June 2009, having flown over 22,000 hours on 8,500 sorties, they were replaced by several RAF Tornado GR4s.[75]
GR.9
The GR9 is an upgrade of the GR7, focused on the Harrier II's avionics and weapons. Upgraded under the JUMP programme.[35]
