The Pentagon’s flagship F-35 fighter jet program may require an additional $38 billion to cover maintenance costs stemming from technical issues with the cooling system that results in engines overheating, US government auditors have said.
In a new report released on Tuesday, the US Government Accountability Office (GAO) pointed out that the F-35 program “continues to experience schedule delays, cost growth, and late deliveries.”
The Pentagon is also struggling to complete a flight simulator for the jet, a necessary step to demonstrate that the aircraft is ready for full-rate production, even though over 125 units per year are already being manufactured, the report says.
Meanwhile, since 2019 procurement costs have soared by $13.4 billion, partly because the Pentagon stretched out purchases of the aircraft over a longer period of time, the report reads, although it states that the “program’s cost reporting mechanisms do not fully explain the reasons for cost growth.”
Despite the colossal expenditure, in March US Air Force Lieutenant General Michael Schmidt, the program’s manager, said that while the Pentagon has more than 540 F-35s, only about half of them are capable of going on a limited variety of missions. Moreover, he estimated that less than 30% of the jets could be described as fully combat-ready.
