The F-35 fighter will now cost more than $2 trillion

The eye-popping price tag has not fixed the maintenance issues plaguing the program, a government watchdog says

The F-35 fighter jet program will cost taxpayers more than $2 trillion over its lifetime, cementing its place as one of the most expensive weapons programs in U.S. history, according to new estimates from the Government Accountability Office (GAO), an independent government watchdog.

The new price tag represents a dramatic jump from a 2018 estimate that set the program’s total cost at $1.7 trillion. Most of the bump comes from projected sustainment costs, which increased by 44 percent to a cool $1.58 trillion over the lifetime of the program. The Pentagon also extended the projected life of the plane to 2088 rather than the previous goal of 2077.

The news comes as Congress considers President Joe Biden’s budget proposal for next year, which asks for a record $895 billion in military funding. The spending package is separate from the White House’s request for $106 billion to fund weapons transfers to and security cooperation with Israel, Taiwan and Ukraine, which is still languishing in the House after passing the Senate earlier this year.

Of course, it’s not all bad news on the financial front. The Pentagon has brought down the estimated lifetime cost per F-35 by simply buying more jets and reducing the number of flight hours they will be expected to perform each year, according to the GAO.

But this is less than ideal on the war-fighting side of the equation. All three versions of the F-35 continue to fall far short of their target “mission capable rates,” a term of art referring to the percentage of time that any given aircraft is actually ready for battle. In 2023, the average F-35A was only in flying shape about 52% of the time — far short of the 90% target set by the Air Force, the GAO reports.

The jets have often been stuck on the ground due to engine design flaws that cause the aircraft to overheat, damaging parts and boosting maintenance costs. This inability to stay in the air has made it more difficult to get pilots sufficient training in real-life scenarios, which increases the likelihood of crashes and other costly accidents, according to Dan Grazier of the Project on Government Oversight.

The effort to fix these engine issues helps show why the F-35’s costs keep rising. In the early 2010s, the Pentagon asked military contractors to propose a new engine prototype while simultaneously pushing RTX subsidiary Pratt and Whitney to upgrade its original F-35 engine. Last year, the Defense Department told Congress that it no longer needs the $588 million per year prototype program, but lawmakers refused to kill it, choosing instead to fund the prototype and the upgrades simultaneously in a move one expert derided as “just throwing money at everything.”

Members of Congress defended the decision to keep the prototype by arguing that it will help advance technology for the next generation of fighter jets. Rep. Mike Rogers (R-Ala.) — a lead proponent of keeping the General Electric-led engine program — also happens to have a brand new GE Aerospace plant in his district.

Besides parochial concerns, the Pentagon also tends to underestimate the cost of programs in early stages of development. Just last week, the Congressional Budget Office revealed that the Navy drastically underestimated the cost of a new medium landing ship to carry small Marine Corps units. Early estimates put the program’s cost at $2.6 billion, but CBO says the Pentagon will most likely have to shell out between $6.2 billion and $7.8 billion for the ships — an overrun of more than 100%.

Gutting military testing office may be the deadliest move yet

Military Industrial Complex

With the stroke of a pen, Secretary of Defense Pete Hegseth has gutted the Pentagon’s weapon testing office.

His order is intended to “eliminate any non-statutory or redundant functions” by reducing the office to 30 civilian employees and 15 assigned military personnel. The order also terminates contractor support for the testing office.

Egypt's energy gamble has left it beholden to Israel

Middle East

As the scorching summer season approaches, Egypt finds itself once again in the throes of an uncomfortable ritual: the annual scramble for natural gas.

Recent reports paint a concerning picture of what's to come, industrial gas supplies to vital sectors like petrochemicals and fertilizers have been drastically cut, some by as much as 50 percent. The proximate cause? Routine maintenance at Israel’s Leviathan mega-field, leading to a significant drop in imports.

But this is merely the latest symptom of a deeper, more chronic ailment. Egypt, once lauded as a rising energy hub, has fallen into a perilous trap of dependence, its national security and foreign policy options increasingly constrained by an awkward reliance on Israeli gas.

For years, the Egyptian government assured its populace and the world of an impending energy bonanza. The discovery of the gargantuan Zohr gas field in 2015, hailed as the largest in the Mediterranean, was presented as the dawn of a new era. By 2018, when Zohr began production, President Abdel Fattah el-Sisi declared that Egypt had "scored a goal," promising self-sufficiency and even the transformation into a regional gas exporter. The vision was that Egypt, once an importer, would leverage its strategic location and liquefaction plants to become a vital conduit for Eastern Mediterranean gas flowing to Europe.

Billions were poured into new power stations, further solidifying the nation's reliance on gas for electricity generation, which today accounts for a staggering 60 percent of its total consumption.
