Trump Orders US Navy to Return to Steam Catapults for Doris Miller Aircraft Carrier
<>
The United States Navy faces a potential multi-billion dollar redesign of the future aircraft carrier Doris Miller following a directive from President Donald Trump to abandon modern electromagnetic launch systems in favor of traditional steam-powered catapults. Ford-class carriers.
The Shift from Electromagnetic to Steam Propulsion
The directive, issued in a memorandum and accompanying fact sheet from the White House, mandates that Secretary of War Pete Hegseth formulate a plan within 60 days to integrate steam catapult systems into the Doris Miller, which is currently in the early stages of construction. This decision effectively reverses the Navy’s recent trend of utilizing the Electromagnetic Aircraft Launch System (EMALS), a technology designed to function similarly to high-speed rail, in favor of the legacy steam-based valves and piston systems used on the ten Nimitz-class carriers.
While the Gerald R. Ford-class utilized EMALS to streamline operations and reduce manning requirements—reportedly saving the Navy approximately $100 million annually in maintenance costs—critics within the administration argue that the program has been plagued by developmental delays and reliability failures.
Financial and Operational Implications for Defense Procurement
The geopolitical and fiscal consequences of this decision are substantial. Furthermore, this architectural pivot risks delaying the vessel’s entry into service, which was originally projected for 2034, potentially pushing the operational capability into the end of the following decade.
Expert Analysis: Technological Regression vs. Proven Reliability
Chris Cavas, a veteran journalist specializing in naval affairs, described the White House memorandum as reflecting “very old and outdated thinking” in discussions reported by CNN. Cavas pointed to the tangible performance differences between the two systems, noting that the electromagnetic system significantly reduces the mechanical stress and structural fatigue placed on aircraft during the launch process.
The Global Ripple Effect on Defense Strategy
The U.S. Navy’s decision carries implications far beyond the domestic shipyard. As the world’s primary maritime power, changes to U.S. carrier design impact the interoperability of allied naval forces and the long-term planning of international defense partners. The shift toward steam, a technology that many global navies have sought to modernize away from, may complicate joint operations or maintenance protocols for international partners who have aligned their own systems with the U.S. technological standard.
Moreover, the anticipated multi-year delay in the Doris Miller’s commissioning could create a temporary capability gap in the Pacific and Atlantic theaters.
Whether this maneuver successfully addresses the underlying maintenance woes of the fleet or merely introduces a new generation of technical and financial inefficiencies remains to be seen. As the White House moves forward with its 60-day planning window, the global defense community remains in a state of adjustment, awaiting the final engineering specifications that will define the future of the U.S. carrier fleet.
