RTX Collins Aerospace EPACS power, cooling system completes altitude testing
RTX•RTX•RTX•RTX•EPACS targets higher cooling capacity to support planned F-35 technology upgrades, aiming to preserve performance margins over the aircraft’s lifecycle.
The milestone follows a 2025 determination that EPACS met requirements for aircraft integration.
RTX reported successful altitude testing of Collins Aerospace’s Enhanced Power and Cooling System (EPACS) for the F-35’s next-generation power and thermal management.
Testing validated performance in flight-like conditions, including operation at mission-level power for several days across multiple altitudes.
