According to a story on the Air Force's Web site, Air Force officials released Friday the candidate basing locations and the criteria they used to determine the candidate basing locations for additional C-17 Globemaster III aircraft.

The list of candidate bases was approved by the secretary and chief of staff of the Air Force: Eastern West Virginia Regional Airport in Martinsburg, W.V.; Memphis International Airport, Tenn.; and Stewart International Airport, N.Y.

The basing criteria were approved by the secretary and chief of staff of the Air Force and considered factors such as mission requirements, airspace, facilities and infrastructure, support capacity, environmental impacts and cost. 

Site surveys will be conducted and the formal environmental impact analysis process will begin, allowing communities around each candidate base to participate and provide input. Based on the results of these efforts, officials expect to announce the preferred locations in November 2010. 

Once the environmental impact analysis processes are complete, Air Force officials will announce the final basing decisions. The announcement is anticipated in June 2011.
