Boeing [BA] last week renamed its Integrated Defense System division to Boeing Defense, Space & Security, realigning and consolidating some of the business units that make up the division’s operating segments.

The operating units remain the same: Boeing Military Aircraft, Network and Space Systems (N&SS), and Global Services & Support. The realignments are taking place within these units.

The Combat Systems division and Command, Control & Communications Networks division within N&SS have been consolidated under the new Network and Tactical Systems division. Within the Military Aircraft operating unit, the Weapons business is now a division rather than a subdivision of the Global Strike Systems division.

Boeing said that changing the name of its defense business reflects a changing marketplace.

“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,” Dennis Muilenburg, president and CEO of Boeing Defense, Space & Security, 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.”

Muilenburg said the realignment allows the company to maintain its “core programs even as we enhance Boeing-wide capabilities designed to capture business in promising markets in the United States and around the world, including cyber security, energy, intelligence, C4ISR and logistics.
