Textron named Lisa Atherton, president and CEO of the Textron Systems segment, to a new role as chief operating officer of the Bell segment. Tom Hammoor, who most recently led Textron Aviation Defense, will succeed Atherton as president and CEO of the Textron Systems segment.

Atherton joined Textron Defense Systems in 2007. In 2013, she transitioned to Bell and held leadership positions within military programs, including executive vice president of military business. In 2017, she was named president and CEO of Textron Systems. A graduate of the U.S. Air Force Academy, she later spent eight years at Air Combat Command’s Directorate of Requirements.

Hammoor has more than 38 years of leadership experience in the defense industry and military service to Textron Systems. Hammoor most recently served as the president and CEO of Textron Aviation Defense from 2016 to 2022. Prior to joining Textron, Hammoor had a nearly 30-year career with General Electric, encompassing leadership roles in quality, manufacturing and customer service. He graduated from the U.S. Military Academy. His military career culminated in the 101st Airborne Division in which he served as scout/attack helicopter platoon leader.

“Lisa’s leadership and experience with military programs at Bell and Textron Systems will be invaluable as we ramp up and execute on the U.S. Army’s Future Long-Range Assault Aircraft program,” Scott C. Donnelly, chairman and CEO of Textron, said. “We are also fortunate to have a leader like Tom, who brings tremendous expertise, leadership and business acumen to his new role at Textron Systems.”
