Honeywell Aerospace to Build $500 Million, 300,000-Square-Foot Manufacturing Facility in Tempe, Arizona

Honeywell Aerospace has announced a $500 million, 300,000-square-foot manufacturing facility in Tempe, Arizona, near the company's global headquarters. The expansion is intended to meet growing demand across commercial aviation and defense programs, and the plant is scheduled to open in late 2028.

The facility will feature an integrated digital production system, modular robotics, automated inspection and digital twins, all powered by an end-to-end digital thread. It will add internal complex machining capability, an area of the supply base that is currently constrained, and will establish a more vertically integrated production system for next-generation products including Assure advanced actuation systems and Attune vapor cycle cooling subsystems.

The plant will support growth on current programs, $15 billion in Control Systems new program wins, and future aviation programs. It will also add capacity for priority production of critical defense technologies covered by a supplier framework agreement the company signed.

Over time the facility is expected to create approximately 600 jobs, and construction will support more than 1,000 local jobs. Jim Currier, president and chief executive officer of Honeywell Aerospace, said demand for the company's technology continues to accelerate across commercial and defense markets, and that the company's recent spin-off into an independent, publicly traded business allows it to make investments supporting its growth and the future of aviation and defense.

The choice to bring complex machining inside the plant targets a part of the supply base already described as constrained. Suppliers that depend on outside machine shops for critical components are exposed to those shops' capacity limits, so pulling that step in-house is a way of securing throughput for the actuation and cooling products the plant is built around. A vertically integrated line also gives a manufacturer tighter control over inspection data, which the digital thread and automated inspection described for the site are meant to capture.

The announcement also shows how a newly independent aerospace business can commit capital on a long horizon. A late-2028 opening ties the investment to program wins that are already booked rather than to speculative demand, and the explicit link to a defense supplier framework agreement places commercial and defense output under one roof. For airframers and operators further down the chain, the practical significance is in supply of actuation and thermal-management hardware on current and future programs, not in the factory itself.

The dated milestone to follow is the late-2028 opening, along with the build-up toward roughly 600 permanent jobs, which the announcement frames as happening over time rather than on opening day.
