what is the primary role of the harrier gr9
British Aerospace Harrier II The RAF used Harriers in the ground attack and reconnaissance roles, so they relied on the short-range AIM-9 Sidewinder missile for air combat. The Sidewinder had proven effective for Royal Navy's Sea Harriers against Argentinian Mirages in the Falklands conflict; however, from 1993 the Sea Harrier FA2 could also carry the much longer-range AIM-120 AMRAAM, a radar-guided missile. The Sea Harrier had a radar since its introduction and the USMC later equipped their AV-8B Harriers with a radar as part of the AV-8B+ upgrade; however Britain's Harrier IIs never carried a radar. When the Sea Harrier was retired, it was suggested that its Blue Vixen radar could be transferred to the Harrier IIs. However, the Ministry of Defence rejected this as risky and too expensive; the Armed Forces Minister Adam Ingram estimated that the cost would be in excess of £600 million.[21][N 2]
