Honeywell Aerospace will spend $500 million to construct a 300,000-square-foot manufacturing facility in Tempe, Arizona. The company announced the project on October 28, 2026, citing accelerating demand in commercial aviation and defense markets. The new plant is scheduled to open in late 2028.
The facility is designed to resolve specific supply chain bottlenecks by adding internal complex machining capability. This process is currently a constrained area within the aerospace supply base. By bringing this production in-house, the company aims to create a more vertically integrated system. The plant will support next-generation products, including Assure advanced actuation systems and Attune vapor cycle cooling subsystems.
The construction phase will generate more than 1,000 local jobs. Once operational, the facility will support approximately 600 permanent positions. These roles will increase the company's engineering depth and skilled workforce in the Phoenix metro area. The new site will sit near the company's global headquarters on the existing Tempe campus.
The building will feature an integrated digital production system, modular robotics, and automated inspection tools. It will rely on digital twins and an end-to-end digital thread to manage operations. This setup is intended to support the largest commercial and defense customers in the industry. The expansion also aligns with a supplier framework agreement the company signed with the Department of War in March.
Jim Currier, president and chief executive officer of Honeywell Aerospace, stated that the investment ensures the company can deliver to customers while driving long-term shareholder growth. He noted that the company's recent spin into an independent, publicly traded entity allows for faster decision-making. Currier said the expansion reinforces the company's commitment to Arizona employees and the global customers who depend on its technology.
The project will support $15 billion in new Control Systems program wins. It will also provide capacity for priority production of critical defense technologies. The company currently employs more than 36,000 people globally and supports over 10,000 customers. Its technologies are deployed on commercial air transport, business aviation, defense, and space platforms.
