The Boeing Co. will realign its military aircraft business - a move that is expected to result in some work force reductions.

The move is aimed at Boeing Military Aircraft's transformation from a "product-based business" to one focused on capabilities, company officials said.

"This reorganization, coupled with our productivity goals, will reduce organizational complexity and allow us to be more efficient," Boeing Military Aircraft President Chris Chadwick said today in a statement.

Boeing will cut just under 20 executive positions in its military aircraft business. Boeing anticipates "additional reductions across all levels of the organization are anticipated in coming months." 

No local manufacturing jobs are expected to be affected by this  restructuring. However, St. Louis-based Boeing Defense, Space & Security was already looking to reduce as many as 400 jobs, a spokesman said.

The four new divisions are: Global Strike, based in St. Louis; Mobility, based in Ridley Park, Pa.; Surveillance and Engagement, based in Seattle; and Missiles and Unmanned Airborne Systems, based in St. Charles.

Boeing Military Aircraft spokesman Damien Mills said the St. Louis- based global strike division will now oversee rotorcraft, such as the AH-64 Apache, as well as fighter jets and training aircraft.

The realignment takes effect on Oct. 1.

Chadwick said the changes will allow the company to meet domestic and global defense requirements for the next decade and beyond.

Boeing's Defense, Space & Security unit is a $34 billion business that employs 68,000 people worldwide.
