Boeing Integrated Defense Systems has been renamed Boeing Defense, Space & Security as part of a corporate reorganization announced Jan. 7.

The renamed division will remain headquartered in St. Louis and will retain its current operating units: Boeing Military Aircraft, Network and Space Systems, and Global Services & Support.

Two divisions within Network and Space Systems — Combat Systems and Command, Control & Communication — will be combined into a new Network and Tactical Systems Division led by Charles Toups, previously a Boeing vice president of engineering and mission assurance. Toups will report to Roger Krone, who remains president of Boeing Network and Space Systems.

“Boeing anticipated flattening defense budgets and shifting customer priorities for the past few years and has been taking aggressive steps to position the company for profitable growth in a challenging economy,” Boeing Defense, Space & Security President and Chief Executive Officer Dennis Muilenberg said in a statement. “In the past 18 months alone, we have acquired seven companies to enhance existing capabilities, expanded Boeing’s services business, and created new divisions — like Unmanned Airborne Systems — to directly and rapidly respond to our customers’ emerging priorities.”
