Orbital ATK has announced an expansion of its Gilbert engineering operations, a project that will create about 155 jobs.

Orbital, a leading aerospace and defense technology firm, said March 18 that it will add 60,000 square feet to its satellite manufacturing facility. 

With additional facilities in Chandler and Mesa, Orbital’s total footprint in the state is almost 800,000 square feet, contributing to over 1,750 high-tech and high-paying aerospace and defense jobs.

The new jobs will be added over a five-year period.

“I am thrilled that one of the largest aerospace and defense companies in the world once again has selected Arizona for its expansion plans, and to support its critical operations,” said Gov. Doug Ducey. “Arizona is a major player globally when it comes to aerospace, defense and avionics – and we continue to grow. This is a great partnership.”

Orbital designs, builds and delivers space, defense and aviation systems for customers around the world, both as a prime contractor and merchant supplier.

Headquartered in Dulles, Va., Orbital ATK employs approximately 12,000 people in 18 states across the U.S. and in several international locations.

Orbital’s heritage satellite business began in Gilbert in 1989 and has 261 employees working at the existing site. 

The expansion plans complement Arizona’s robust aerospace and defense sector that contributes $38 billion annually to the Arizona economy and employs more than 52,000 workers.

“Today, our facility in Gilbert produces cutting-edge satellites for a variety of customers both domestic and international,” said Rick Kettner, Orbital’s Gilbert site director.  “This cooperative agreement with the state of Arizona and Gilbert helps ensure we will continue to do so for years to come.”
