The Air Force announces plans to base its MC-12W Liberty intelligence-surveillance- reconnaissance aircraft at Beale AFB, Calif. (The base will receive the first of its planned seven training aircraft June 10, 2011; the bulk of the 37-aircraft fleet are expected to be deployed overseas.)
The U.S. began extensive air and artillery strikes against Islamic State group targets in Syria on Dec. 19 in retaliation for the killing of three Americans on Dec. 13 by a gunman affiliated with ISIS, U.S. officials said.
