As expected, Northrop Grumman [NOC] on Tuesday said that its board has elected Kathy Warden as its chairman effective Aug. 1, adding to her current duties of president and CEO of the $30 billion defense company.

Warden succeeds Wes Bush, who has been the company’s chairman since July 2011. Bush will resign from the board effective July 31. Warden became CEO on Jan. 1, 2019, and previously was president and chief operating officer.

“We are excited to have Kathy Warden assume the role of chairman,” Donald Felsinger, lead independent director on the company’s board, said in a statement. “She has the full confidence of the board and our shareholders, customers and employees will greatly benefit from her leadership.”
