Boeing [BA] Commercial Airplanes (BCA) President and CEO Scott Carson will retire from the company at the end of the year and be replaced by Jim Albaugh, current head of Integrated Defense Systems (IDS) unit, the company said yesterday.

Dennis Muilenburg will succeed Albaugh as president and CEO of IDS. Both appointments are effective Sept. 1.

Albaugh, a 34-year company veteran with extensive experience in development programs and manufacturing, has led Boeing’s defense, space and associated services businesses since 2002. Under his leadership, IDS revenue has grown from $25 billion to an expected $34 billion in 2009, and now accounts for roughly half of Boeing’s annual sales. Prior to his most recent assignment, he led Boeing’s growth in space and communications, including network-centric operations, global missile defense, combat systems, and system-of-systems technologies. He began his career with Rockwell’s aerospace and defense businesses, which Boeing acquired in 1996.

“Jim is a seasoned and effective aerospace executive with substantial experience leading and integrating technically complex businesses and programs from initial development through full production and delivery,” Boeing CEO James McNerney said. “His program management and engineering focus will help ensure the success of BCA’s key development and production programs.”

Muilenburg moves to his new position from IDS’ Global Services & Support unit, where he served as president of the $8 billion business that provides global after-delivery support for military platforms and systems, as well as a broad array of defense and government services. Prior assignments include leadership of the Combat Systems Division and Future Combat Systems, the modernization program for the U.S. Army. He also led the overall engineering development of Boeing’s program to modernize global air traffic management systems.

A replacement for Muilenburg will be named at a later date, according to a company press statement.
