Herrick (War in Afghanistan). These included 6 to 8 Tornado GR4 aircraft drawn from different parts of the Royal Air Force as well as multiple Vickers VC10 from the No. 101 Squadron RAF. British Tornados were equipped with a range of stores, including the Vicon Recce Pod, LITENING targeting pod, 1000 lb HE bombs, Paveway II and Paveway III laser-guided bombs, and the RAPTOR Recce Pod. They were chosen for their currency and up-to-date modification state. The RAF aircraft were accompanied by nearly 400 personnel, of which approximately 130 were aircraft engineers while the remaining 270 were active in support and operation management roles. Squadron personnel were on a two-month rotation at RAF Al Udeid with the remainder of the force on a four-month rotation. Support personnel were on varying rotations but not as often generally as the squadron personnel. The RAF operated from what was known as the "Southern QRA" buildings. Aircraft were housed in canvas shelters to protect them and the personnel working on them from the heat of the sun. RAF Al Udeid was used as a staging post for personnel en route to Iraq (in particular, Basrah) with personnel transferring from passenger aircraft, such as the RAF-operated Tristar and VC10, to the tactical transport Lockheed C-130 Hercules. The Hercules transit was in the region of two hours and mostly in tactical black-out conditions. Royal Australian Air Force As part of Australia's contribution to coalition forces in the 2003 invasion of Iraq, fourteen F/A-18 Hornet fighters from No. 75 Squadron RAAF were based at Al Udeid, along with two P-3 Orion maritime patrol aircraft and three C-130 Hercules military transport aircraft. During the early phases of the war, the Hornets flew long missions escorting and protecting coalition AWACS Early warning aircraft and tanker aircraft used for air-to-air refueling. Later, when the threat to aircraft was reduced, the Hornets switched to the ground attack and combat support roles and were used to attack Iraqi ground forces with laser-guided bombs. The Orions flew long endurance missions over the Persian Gulf tracking vessels, curbing smuggling and guarding against the threat posed by suicide boats. The deployed Hercules flew supplies and equipment into Iraq, and later flew some of the first humanitarian aid into Baghdad. The fourteen Royal Australian Air Force Hornets flew over 670 sorties during the war, including 350 combat sorties over Iraq. Following Australia's formal withdraw of forces
