Reverting to Steam Catapults Could Haunt the Navy for Decades
Replacing EMALS with steam catapults on future carriers may solve short-term cost concerns while creating far deeper operational and industrial problems.
A proposal to abandon the Navy’s electromagnetic launch system on future aircraft carriers and return to steam catapult technology carries risks that could compound over decades, according to a detailed analysis by The War Zone. The piece, headlined “Bringing Back Steam Catapults On Carriers Is A Huge Risk,” argues that what appears on the surface to be a cost-cutting or reliability fix is, in practice, a decision with sweeping and potentially irreversible consequences for American carrier aviation. For a Navy already grappling with a carrier readiness crisis that has no near-term resolution, adding long-term capability regression to the equation raises serious questions about strategic direction.
The debate was reignited in part by online commentary circulating in defense circles that drew renewed attention to the diverging technology trajectories of the U.S. and Chinese carrier programs.
What Reverting to Steam Actually Means in Practice
The Electromagnetic Aircraft Launch System, known as EMALS, has had a troubled developmental history. Early reliability problems aboard USS Gerald R. Ford drew sustained congressional and Pentagon criticism. But The War Zone’s analysis stresses that those problems have been addressed through successive software and hardware fixes, and that EMALS now represents a mature system with significant performance advantages over steam — including more precise energy control, reduced stress on airframes, and a smaller mechanical footprint that frees space for other ship systems.
Steam catapults, by contrast, require large below-deck infrastructure — steam accumulators, complex piping, and maintenance-intensive machinery — that EMALS was specifically designed to eliminate. Rebuilding that industrial and engineering knowledge base after years of transition away from it is not straightforward. Suppliers, trained technicians, and design documentation centered on steam launch technology have atrophied. Reconstituting that supply chain would take years and carry its own cost and schedule risks, undermining the very efficiency argument used to justify the reversal.
Strategic and Industrial Costs of Going Backward
The War Zone analysis makes the case that the decision is not merely technical but strategic. EMALS is designed to launch a broader range of aircraft, including future unmanned systems and potentially next-generation platforms that steam systems cannot accommodate without significant modification. Locking the next generation of carriers into steam infrastructure effectively constrains the Navy’s options for integrating autonomous and advanced strike aircraft over a hull’s 50-year operational lifespan — a period in which the character of naval aviation is expected to change substantially.
There is also the question of international signaling. As China accelerates its own electromagnetic catapult program, a U.S. decision to step back from the technology would be read by competitors and allies alike as a retreat from the leading edge of carrier capability. The Navy has invested heavily in sustaining that edge, and the credibility cost of reversing course is not easily quantified but is nonetheless real. Critics of the reversal proposal argue that short-term budget relief does not justify handing adversaries a talking point — or, more consequentially, an actual capability advantage — on a platform that anchors U.S. power projection worldwide. Readers tracking related naval engineering vulnerabilities may also find the account of an adrift Navy destroyer in the South China Sea a useful illustration of how technical failures cascade operationally.
