F-35’s Cooling Crisis: Design Flaws Fuel $2 Trillion Dilemma for Pentagon

Commentary

The Pentagon is facing a tough decision regarding the F-35’s ongoing issues with overheating due to inadequate cooling capacity.

Should taxpayers fund a costly upgrade to address immediate cooling needs, or opt for a more expensive upgrade to handle potential future cooling requirements?

Before we delve into the two options facing the Pentagon, let’s explore why cooling capacity is crucial for the F-35 and how its design shortcomings led to this crisis.

Sufficient cooling is essential as the F-35’s advanced systems generate heat, requiring more than just air cooling. Liquid cooling, especially for power-intensive radars, is crucial for managing the heat produced by the F-35’s complex electronics.

The F-35, touted as a flying supercomputer, houses numerous heat-generating components, with its AN/APG-81 AESA radar being a major contributor to this heat load.

The F-35’s design led to a significant heat load, necessitating a robust cooling system to support its advanced capabilities and maintain its status as a top-tier fighter.

The decision to under-spec the F-35’s cooling capacity stemmed from design compromises that prioritized weight reduction over accommodating future growth, leading to the current cooling crisis.

The F-35’s engine was initially designed with inadequate cooling capacity, which became apparent as new capabilities were added, requiring more cooling power and impacting engine reliability.

Ultimately, the choice to under-spec the F-35’s cooling system was a result of design trade-offs to maintain performance parameters, despite the inevitable consequences for cooling and engine reliability.

Now, the Pentagon faces a dilemma on whether to invest in a short-term fix or a long-term solution to address the F-35’s cooling challenges.

From a sales perspective, the Pentagon is presenting us with a choice of two positives to focus on. However, before making a decision, it’s important to take into consideration that the current F-35 engines are deteriorating faster than expected. The engine control units that are supposed to improve reliability won’t have their design completed until 2029.

Moreover, there is uncertainty surrounding the delivery of the much-needed engine core upgrade from Pratt & Whitney in 2029. This raises doubts about whether it will be delivered on time or if it will actually enhance the reliability of the F-35 engine.

Given the increasing risks and costs associated with the F-35 program, it may be wise to explore creative solutions to ensure our existing F-35s can operate with a reasonable level of reliability. Instead of producing new F-35s, we should consider carefully selected hardware and software capabilities that do not require additional power and cooling.

This approach would represent a significant achievement in addressing the challenges faced by the F-35 program.
