Air Force Secretary Deborah Lee James has appointed Defense Department veteran Darlene Costello to serve as principal deputy assistant secretary for acquisition and logistics at the military branch.
Costello succeeds Richard Lombardi, who has been reassigned to a non-acquisition role within the Air Force, the service announced Thursday.
She has served as principal deputy assistant secretary for acquisition at the Office of the Under Secretary of Defense for Acquisition, Technology and Logistics since September 2014.
In that capacity, she advised DoD leadership on military and business system acquisition, strategic, space, intelligence, tactical warfare and command and control matters.
Costello previously held the role of deputy assistant defense secretary for strategic and tactical systems on an acting basis as well as principal director of S&TS and director of acquisition and program management at DoD.
She also worked at the U.S. Navy, where she oversaw 15 shipbuilding programs and associated weapon systems as its deputy director for naval warfare.
