A Phoenix-based aerospace and defense company is expanding in Arizona months after breaking off from its parent company.

Honeywell Aerospace is planning a $500 million, 300,000 square-foot manufacturing facility in Tempe. The facility is expected to create 600 jobs. Honeywell Aerospace, which spun off parent company Honeywell earlier this year, employs roughly 8,000 people in the Phoenix area.

The facility will manufacture systems and parts for commercial and defense aircraft, including engine start and environmental control systems. The facility will oversee a large part of the manufacturing process, according to spokesperson Adam Kress.

“Material can enter the facility and move through machining, head treatment, subassembly, final assembly, testing, inspection, and shipment within a highly integrated production environment,” Kress wrote in an email to The Arizona Republic. “That end-to-end manufacturing approach improves efficiency and provides greater visibility across the production process.”

Tempe Mayor Corey Woods described the project as the “largest aerospace investment” in the city’s history. The facility is expected to open in 2028.

“This key project sets the stage for further growth and development of our region’s aerospace, technology and manufacturing sectors, helping to strengthen Arizona’s position in the global market,” Woods said in a statement.

Honeywell Aerospace manufacturers supportive technology for the aerospace industry, including engines and aircraft systems for navigation, communication and auxiliary power. Arizona, a historic hub for space science, has sought to expand the aerospace industry amid a renewed national interest in space.

The company — traded on the Nasdaq under the ticker symbol HONA — announced its third-quarter earnings Oct. 28. Honeywell Aerospace reported $737 million in net revenue, up 13% from the previous year.

Honeywell Aerospace is currently testing technology at Phoenix Sky Harbor International Airport and two other Arizona airports to better alert pilots to runway traffic.
