Northrop Grumman said today it would reorganize itself into four new sectors -- aeronautic systems, defense systems, mission systems and space systems -- effective Jan. 1.
Northrop's current sectors are aerospace systems, mission systems, innovation systems and technology services.
Northrop said today Patrick Antkowiak, the company's chief strategy and technology officer, as well as Christopher Jones, president of the technology services group, will retire.
Under the new structure, Janis Pamiljans, the current president of aerospace systems, will lead the aeronautic systems business. The defense systems business -- which will include technology services, sustainment and modernization, directed energy, tactical weapons and information systems -- will be led by Mary Petryszyn, who is general manager of the land and avionics C4ISR business within mission systems.
The mission systems unit, which will specialize in software-defined systems for defense and intelligence applications, will be headed by Mark Caylor, who leads the current mission systems unit. The space systems group will be spearheaded by Blake Larson, who heads innovation systems.
The company has made changes to its technology services business multiple times in recent years.
Earlier this year, Northrop consolidated two groups within the unit, in a move meant to position it to grow.
In 2017, Northrop realigned the technology services business to shift away from lower-margin work.
