Honeywell Aerospace Upgraded F-35 Power Systems
Defense contractors and their supply chain partners face shifts in manufacturing capacity requirements.
Updated on Sept. 22, 2026 in Manufacturing

In September 2026, Honeywell Aerospace launched a 40 kW Power and Thermal Management System (PTMS) upgrade for the F-35 aircraft. This move supports the goal of increasing fleet readiness and mission effectiveness.
Why it matters
The upgrade aims to address long-standing concerns regarding aircraft availability and mission effectiveness for the F-35 fleet. These improvements reflect an ongoing industry focus on upgrading core platform performance to meet modern defense requirements.
Honeywell Aerospace now maintains an annual F-35 aircraft production capacity of 156 units. The company also implemented a 40 kW upgrade to the Power and Thermal Management System to enhance aircraft utility.
The players
Honeywell Aerospace
An independent aerospace manufacturer and service provider focused on defense and commercial aviation systems.
Matt Milas
A leader at Honeywell Aerospace responsible for guiding operational strategy and business execution.
The details
To achieve these capacity goals, Honeywell Aerospace expanded its footprint by onboarding additional suppliers and increasing capital equipment investments. The company is now embedding its own employees directly into supplier facilities to manage the specialized manufacturing work on-site. This operational shift centralizes production control to ensure consistency across the supply chain.
Timeline
June 2026: Honeywell Aerospace became an independent entity.
September 2026: The 40 kW PTMS upgrade for the F-35 was launched.

Market Landscape
This production expansion follows the organizational shift that occurred when Honeywell Aerospace became an independent entity in June 2026. The company's ability to scale is now tied to the U.S. Congressional appropriations process for defense spending.
Operators in the defense supply chain should monitor future Congressional appropriations, as these will dictate potential surge production volumes. Review current manufacturing contracts for clauses regarding on-site support, as OEMs may increasingly place personnel at supplier facilities.
The takeaway
Reliability in defense manufacturing now requires both increased capital equipment and direct oversight of supplier-based production. Keep track of the alignment between Department of Defense mandates and budget cycles to gauge demand shifts for specialized components.
