Failing F-35 fighter grounded once again

A faulty engine caused the $1.7 trillion boondoggle fighter to crash during a December quality check.

Defense News reported on Wednesday that defense contractor Pratt & Whitney is suspending its deliveries of new F-35 engines, following a setback on a Texas runway last month. Video from the December 15 incident shows a Lockheed F-35B Lightning II crashing during a quality check and the pilot ejecting. 

Last Friday, in the aftermath of the incident, Defense News first reported that Lockheed Martin had “announced it halted acceptance flights and deliveries of new F-35 Joint Strike Fighters” due to the ongoing investigation. As a result, Lockheed Martin delivered seven fewer aircraft than the 148 that they were contracted to deliver in 2022. According to that report, “A source familiar with the program told Defense News the investigation into the Dec. 15 mishap found that a tube used to transfer high-pressure fuel in the fighter’s F135 engine, made by Pratt & Whitney, had failed.” 

Pratt & Whitney, which is a subsidiary of Raytheon, and earlier in December received a $115 million contract from the Department of Defense for an F135 engine enhancement program, told Defense News that they would not comment since an investigation into the crash was ongoing. 

Problems relating to the F-35’s engines are nothing new. A Government Accountability Office (GAO) report from April 2022 revealed that Pratt & Whitney delivered only six of 152 F-35 engines on time in 2021, “primarily due to quality issues that required resolution before engines could be accepted by the government.” And yet, through last year, Congress continued to fund the F-35 beyond the Pentagon’s requests. As Nick Cleveland-Stout noted in RS last year, the FY 2020 Defense Appropriations Act allocated funds for 22 more F-35s than DoD had asked for. 

The F-35 aircraft additionally has been mired in other major problems. Dan Grazier wrote for RS in March that a non-public 2021 Pentagon’s Director, Operational Test & Evaluation testing report “showed that engineers are still trying to correct 845 design flaws. Their challenge is compounded by the fact that new problems are discovered almost as fast as the known flaws are fixed.” 

Beyond consistent quality issues, the F-35 is also among the most expensive Pentagon programs ever. As a letter signed by a transpartisan group of organizations — including the Quincy Institute — last summer exclaimed, “Over the service life of the fleet, the F-35 program is projected to cost the American people $1.7 trillion. This is roughly $5,000 for every man, woman, and child in the nation.” 

In the more than 20 years since Lockheed Martin won the competition to develop the F-35, more than $62.5 billion has been spent on the program’s research and development, according to Grazier. “Despite all that time and resources, the F-35 remains an underdeveloped aircraft,” he writes, “it will still take years to complete the design during a process program officials have dubbed ‘modernization’ but is really a second chance to finish work that should have been completed during the initial development effort.”

The latest mishap involving these engines caused the F-35 Joint Program Office to pause deliveries on December 27, and to ground a number of F-35s. It is unclear at this time how many aircraft were grounded or how long the groundings will last.

The roots of Trump's wars on terror trace back to 9/11

Global Crises

The U.S. military recently launched a plainly illegal strike on a small civilian Venezuelan boat that President Trump claims was a successful hit on “narcoterrorists.” Vice President JD Vance responded to allegations that the strike was a war crime by saying, “I don’t give a shit what you call it,” insisting this was the “highest and best use of the military.”

This is only the latest troubling development in the Trump administration’s attempt to repurpose “War on Terror” mechanisms to use the military against cartels and to expedite his much vaunted mass deportation campaign, which he says is necessary because of an "invasion" at the border.

Is Israel forcing Trump to be the capitulator in chief?

Middle East

President Donald Trump told reporters outside a Washington restaurant Tuesday evening that he is deeply displeased with Israel’s bombardment of Qatar, a close U.S. partner in the Persian Gulf that, at Washington’s request, has hosted Hamas’s political leadership since 2012.

“I am not thrilled about it. I am not thrilled about the whole situation,” Trump said, denying that Israel had given him advance notice. “I was very unhappy about it, very unhappy about every aspect of it,” he continued. “We’ve got to get the hostages back. But I was very unhappy with the way that went down.”

Is Europe deliberately sabotaging Ukraine War negotiations?

Europe

After last week’s meeting of the “coalition of the willing” in Paris, 26 countries have supposedly agreed to contribute — in some fashion — to a military force that would be deployed on Ukrainian soil after hostilities have concluded.

Three weeks prior, at the Anchorage leaders’ summit press conference, Russian President Vladimir Putin noted that Ukraine’s security should be ensured as part of any negotiated settlement. But Russian officials have continued to reiterate that this cannot take the form of Western combat forces stationed in Ukraine. In the wake of last week’s meeting, Putin has upped the ante by declaring that any such troops would be legitimate targets for the Russian military.
