Scott Lehr, a senior vice president of Orbital ATK (NYSE: OA), has been promoted to serve as president of the company’s flight systems business group.
He will start his new role on July 1 and succeeds Ron Grabe, who will become a senior adviser for the organization, Orbital ATK said Thursday.
David Thompson, Orbital ATK president and CEO, said Lehr and Grabe helped plan and carry out the integration of the company formerly known as Orbital Sciences with ATK‘s aerospace and defense businesses.
Lehr spent a total of 31 years at ATK and at a predecessor company.
He previously managed ATK’s commercial and defense propulsion systems division and has served as Grabe’s deputy since the merger completed in February.
