Northrop Grumman has announced an organisational realignment to streamline operations, drive growth and improve customer service.

The company will reorganise into four operating sectors of Aeronautics Systems, Defense Systems, Mission Systems and Space Systems.

The organisational changes will be effective from 1 January 2020.

Northrop Grumman chairman, CEO and president Kathy Warden said: “This new operating structure allows us to take full advantage of our company’s portfolio by aligning businesses that have shared markets, customers and technologies.

“It will accelerate our ability to rapidly identify and deliver the technologies, products and services our customers need and fuel our continued growth and execution.”

Aeronautics Systems will focus on providing customers with manned and unmanned air systems. The sector specialises in systems engineering, manufacturing excellence and reliability and will be led by Janis Pamiljans.

Defense Systems will deliver critical technology services, sustainment and modernisation. It will be led by Mary Petryszyn, who is the current vice-president and general manager of Land & Avionics C4ISR, Mission Systems.

The sector will cater to directed energy, integrated battle command systems, tactical weapons and information systems.

Led by Mark Caylor, Mission Systems deals with open, cyber-secure, software-defined systems for defence and intelligence applications.

The fourth business, Space Systems, provides space and launch systems to national security, civil and commercial customers.

The company has also announced that its chief strategy and technology officer Patrick Antkowiak and Technology Services president Christopher Jones are set to retire.
