| Jim Dunnigan questioned why the 173rd Abn air dropped from C-17s on the Kirkuk airbase instead of just landing. (Besides Jim, those troopers would not get their combat jump star on their wings) I looked at the discription of the Kirkuk base (globalsecurity.org) and found one dirt strip and one 2800 meter asphalt strip. To my knowledge, the US Air Force has never landed one of their multimillion dollar fully loaded heavy lifters on an unimproved asphalt or dirt strip. Our heavy cargo planes (C-5/C-17/747s) need wide and thick reinforced concrete runways.(The C-17 has a runway LCN rating of better than 40 on paved, the C-5 is rated at 44 on paved concrete,69 on asphalt. Janes) The touch down area on a comercial 747 rated airfield is 54 inches thick which tapers down to 24 inches on the taxiways (Discovery Channel) It appears that the Kirkuk field is restricted to C-130s for logistics. Maybe we could use the Russian multi-parachute rocket descent reduction system to air drop an Abrams tanks, or better yet, lease the AN-124 with its 12 landing wheels. It can land on unimproved dirt/asphalt field of less than 3000 meters (Janes). |
