Trump orders Pentagon to redesign US aircraft carrier to use steam catapults to launch jets

President has suggested steam catapults every year since 2017, saying digital systems are too ‘complicated’

After nearly a decade of loudly complaining about the fact that modern US aircraft carriers use electromagnetic systems to launch fighter jets instead of steam-powered catapults, Donald Trump has directed the Pentagon to redesign a new aircraft carrier to replace the modern system with the old-fashioned catapults he prefers.

Trump signed a national security memorandum on Thursday directing the defense secretary, Pete Hegseth, and the acting navy secretary, Hung Cao, to make the change he has had his heart set on since at least 2017, when he first described his idea to Time magazine.

The memorandum gives the Pentagon leaders 60 days to come up with “a plan on the required measures to replace the Electromagnetic Aircraft Launch System and Advanced Weapons Elevators with steam and hydraulic systems for the construction of” the USS Doris Miller, a Ford-class aircraft carrier, which is already two years behind schedule .

“You know the catapult is quite important,” Trump told Time magazine in 2017 before recounting a conversation he said he had with an unnamed navy officer.

“So I said, ‘What is this?’ ‘Sir, this is our digital catapult system’”, Trump went on. “It sounded bad to me. Digital. They have digital. What is digital? And it’s very complicated, you have to be Albert Einstein to figure it out. And I said–and now they want to buy more aircraft carriers – I said, ‘What system are you going to be’– ‘Sir, we’re staying with digital.’ I said, ‘No you’re not. You[’re] going to goddamned steam, the digital costs hundreds of millions of dollars more money and it’s no good’”.

A Guardian review of Trump’s public remarks shows that he has retold that story, with variations, every year since 2017.

In 2018, Trump brought it up during a Thanksgiving day phone call with the commanding officer of the USS Ronald Reagan, an aircraft carrier docked in Hong Kong at the time. In 2019, he recounted his conversation with the “catapulter” to Republican donors at a fundraiser. In 2020, as the nation was grappling with a pandemic, the tale became a regular part of Trump’s campaign speeches . In 2021, he told the story at the CPAC convention . In 2022, he shared it in a campaign speech in Texas. He repeated it on the campaign trail in Iowa in 2023. At one of his final campaign events before the 2024 election, Trump told Tucker Carlson the same story.

After he returned to office in 2025, Trump brought up steam catapults during the swearing-in of Tulsi Gabbard as his director of national intelligence and did so again in r emarks to the crew of the USS George Washington , an aircraft carrier based in Japan.

“We built an aircraft carrier for $19bn, which is crazy. The price is crazy,” Trump recalled last month at the Army War College in Pennsylvania. “It had all sorts of modern-day things that were all – instead of using steam for the catapults, they used electric.

“So when I went to the ship, because I came into office and the ship was way over budget, built in Newport News [Virginia],” Trump continued.
