Air Force selects candidate bases for C-27J aircraft operations and training Published Aug. 6, 2010 By Secretary of the Air Force Public Affairs WASHINGTON -- Today the Air Force released its candidate basing decision for the C-27J operations and training aircraft. The Secretary and Chief of Staff of the Air Force approved C-27J operations and training candidate bases. Training candidates are: Key Field Air Guard Station, Miss; Mansfield Lahm Regional Airport, Ohio. Operations candidates are: Boise Air Terminal AGS, Idaho; and Great Falls International Airport, Mont. The Air Force will conduct site surveys at the candidate locations and initiate the environmental impact analysis process in preparation for a final selection. The C-27J is a twin turboprop engine aircraft designed to meet an Air Force requirement for a rugged, medium size airland transport. The C-27J gives US military troops a unique, short-take-off-and-landing capability, providing access to airstrips otherwise unusable by fixed-wing aircraft.
