Elon Musk said the F-35’s makers are ‘idiots’ for still building manned jets as drone tech rises

• Elon Musk criticized the F-35 program on Sunday.
• Musk’s comments come as he prepares to advise Trump on government efficiency in 2025.
• The GAO expects the F-35 program to cost about $2 trillion over its entire lifespan.

Elon Musk, who’s set to start advising President-elect Donald Trump on government efficiency in 2025, criticized the Pentagon’s F-35 program in two social media posts on Sunday.

The billionaire reposted a video montage of coordinated drone swarms on X, writing: “Meanwhile, some idiots are still building manned fighter jets like the F-35.”

He added a “trash can” emoji to his post.

When another X user defended the F-35’s capabilities, Musk responded that the prized jet is a “shit design.”

In another post, Musk said: “Crewed fighter jets are an inefficient way to extend the range of missiles or drop bombs. A reusable drone can do so without all the overhead of a human pilot.”

“‘Stealth’ means nothing”, he added, saying that it’s “laughably easy” to shoot down fighter jets.

Musk has made similar arguments several times over the years.

Mauro Gilli, a senior researcher in military technology at the Center for Security Studies of the Swiss university ETH Zurich, told BI that Musk was echoing valid criticisms of the F-35 program.

But, he said, there were many problems with Musk’s line of thinking.

Gilli acknowledged that the F-35 program has had well-documented cost and time overruns. But those problems are not primarily down to them being crewed aircraft, he told BI.

“The primary source of costs and problems was the electronics and, in particular, the software,” he said.

And that would only get more expensive with a drone equivalent, he added.

“A drone operating within enemy airspace will not be remotely controlled,” Gilli said. “It will need to have a very high level of autonomy.”

This requires even more costly and complex electronics and software than even a piloted aircraft, he suggested.

According to Gilli, Musk’s suggestion is to rely on something that has “so far been the primary source of cost and time delays. And so there is no reason to believe that these drones would be any cheaper.”

Musk’s emphasis on a “reusable” drone also means it would need all the same stealth capabilities as an F-35 in penetrating enemy airspace and evading air defenses, Gilli said, making his comments about stealth a moot point.

A target for DOGE?

It’s unclear if Musk intends to use his new position to impact any plans or costs for the F-35, the Pentagon’s most expensive fighter program to date.

But he mentioned Defense Department spending in a column in The Wall Street Journal that criticized federal government budgets.

“The Pentagon recently failed its seventh consecutive audit, suggesting that the agency’s leadership has little idea how its annual budget of more than $800 billion is spent,” Musk wrote in the column with Vivek Ramaswamy, who is to lead Trump’s new Department of Government Efficiency with him.

Musk and Ramaswamy wrote that the intention of their department is to eliminate the “sheer magnitude of waste, fraud, and abuse that nearly all taxpayers wish to end.”

As for the F-35, costs for the Lockheed Martin-developed stealth jet have hit about $485 billion, after a 10% bump this year due to what the Pentagon said was a need to improve its engine cooling.

Around 1,000 of the planes have been delivered to the US military and its allies, out of a total of over 3,000 aircraft planned for production over the F-35 program’s lifetime.

The jet’s operational lifespan is estimated to last until 2088, and the Government Accountability Office thus expects the F-35 program to cost over $2 trillion to produce and sustain.

Musk did not respond to requests for comment from Business Insider, but he’s said before that the US should consider remote-piloted alternatives to manned jets, both to keep up with the rise in drone warfare and also to help Air Force procurement stay competitive.

In response to Musk’s tweets, a Lockheed Martin spokesperson told BI that the F-35 is “the most advanced, survivable and connected fighter aircraft in the world, a vital deterrent and the cornerstone of joint all-domain operations.”

“As we did in his first term, we look forward to a strong working relationship with President Trump, his team, and also with the new Congress to strengthen our national defense,” they added.

Meanwhile, a Pentagon spokesperson told BI: “We have combat capable aircraft in operation today and they perform exceptionally well against the threat for which they were designed.”

The spokesperson added: “Pilots continually emphasize that this is the fighter they want to take to war if called upon.”
