WASHINGTON—President Trump signed a memorandum Thursday directing the Navy to abandon the electromagnetic catapult systems aboard its newest aircraft carriers and revert to older steam and hydraulic technology—a decision Sen. Mark Kelly (D-AZ) called reckless and expensive.
The directive, titled "Rebuilding the United States Navy and America's Shipbuilding Industrial Base," orders Defense Secretary Pete Hegseth and acting Navy Secretary Hung Cao to produce a plan for switching the launch systems and weapons elevators aboard Ford-class carriers from electromagnetic to steam. Under the order, the next ship in the Ford class—the Doris Miller, currently under construction—will be built with steam catapults. Every subsequent Ford-class carrier added to the fleet will follow the same standard.
Kelly, a Navy veteran, test pilot and holder of a master's degree in aeronautical engineering, did not hold back. "I've launched off the front of aircraft carriers hundreds of times, have a master's degree in aeronautical engineering, and am a test pilot and even I wouldn't suggest to the Navy how to engineer specific systems on its ships," Kelly said. "Donald Trump should stick to what he knows best—ballrooms, bankruptcy, and bulls***."
The electromagnetic systems Trump is moving to retire—known formally as the Electromagnetic Aircraft Launch System, or EALS—are currently installed on the Gerald R. Ford, the John F. Kennedy and the Enterprise, the three carriers already in or entering the Ford class. The technology replaced the steam catapults used on older Nimitz-class carriers, promising greater precision and a lower mechanical footprint. Critics, including Trump, have long argued the systems are too prone to failure and too complex to maintain at sea.
Trump said as much at a defense conference in Pennsylvania in July. "Billions of dollars more they spent on electric catapults and they're not good. They're not nearly as good, too complex," the president said. That language carried almost word for word into Thursday's memorandum, which cited "overly complex designs and iterative design change procedures" as the source of cost growth, delays and program cancellations across Navy shipbuilding.
The directive is not a new impulse. Trump made a similar promise nearly 10 years ago to return aircraft carriers to steam, making Thursday's order the formal fulfillment of a long-standing position. His repeated public complaints about electromagnetic launch systems stretch back to his first term, when he told TIME magazine the Navy should have kept the steam systems that "worked great for 65 years."
The financial consequences of the switch are substantial. Reversing the engineering on the Doris Miller—which is already under construction—and retooling the supplier and design chain for all future Ford-class hulls carries a price tag in the billions, though Thursday's memorandum directed Hegseth and Cao to develop the cost plan rather than stating a final figure.
Kelly's pushback was direct on that point as well. The Arizona Democrat, who flew combat missions in the Gulf War and later commanded the Space Shuttle Endeavour twice, argued the order substitutes presidential preference for engineering expertise at enormous public cost. His criticism puts him in line with defense analysts who have questioned whether the EALS systems' early reliability problems—real and documented during the Ford's initial deployment—justify scrapping the technology rather than continuing to refine it.
The Ford logged persistent EALS problems during its early carrier qualifications, and the Navy spent years and additional funding working through those failures. Supporters of the electromagnetic system argue those problems were characteristic of first-generation deployment on a new platform and have been substantially resolved on subsequent hulls. Opponents, including Trump, say the record of early failures proves the concept was wrong from the start.
Hegseth and Cao now carry the task of translating the presidential directive into an actionable plan—including cost estimates, construction timelines for the Doris Miller and a retrofit or grandfathering decision for the Ford, Kennedy and Enterprise, which already carry the electromagnetic systems. The memorandum does not set a deadline for that plan.
Kelly sits on the Senate Armed Services Committee, giving him a formal role in reviewing defense procurement and Navy shipbuilding budgets. His public attack on the order signals the directive will face pointed scrutiny when it comes before Congress for the funding it will require.
