Boeing [BA] yesterday named Darryl Davis as president, Advanced Systems, for Boeing Integrated Defense Systems (IDS). Davis replaces George Muellner, who recently announced his intent to retire effective Dec. 31.

“Darryl’s extensive background in new product development, his leadership and ability to inspire others, and strong customer focus make him an excellent choice to lead this team into the challenging times ahead,” Jim Albaugh, president and CEO, Boeing Integrated Defense Systems, said in a statement.

Davis will be responsible for working with the three businesses within IDS–Precision Engagement & Mobility Systems, Network & Space Systems and Support Systems–to help them develop cross-cutting concepts and technologies to respond to evolving needs of customers and to address potential new markets.

Simultaneously, Boeing announced Advanced Systems headquarters will move from Long Beach, Calif., to St. Louis, Mo., where IDS is headquartered. David Whelan will remain as deputy in Southern California.

Albaugh said the strategic relocation of the leadership team will allow the creation of greater efficiencies within the organization and provide even better customer value.

Davis, 53, is a 28-year veteran of Boeing. Before this assignment, Davis served as vice president & general manager of advanced precision engagement and mobility systems, a position he held since 2006.
