The Washington Post reported on Saturday that the US Navy is considering a major redesign of its new Ford-class aircraft carriers to better match Trump's preferred aesthetic, with the president favoring ships that more closely resemble US carriers from the World War II era. One option under study would move the carrier's island farther forward, toward the middle of the ship.
US officials cited by the report warned that such a change could require billions of dollars in redesign costs and cause substantial delays.
The potential island redesign comes only days after Trump ordered another far-reaching change to the Ford-class program. On Thursday, he signed a national security memorandum directing the Pentagon and Navy to develop a plan within 60 days to replace the Electromagnetic Aircraft Launch System (EMALS) with steam catapults and the Ford-class carriers' Advanced Weapons Elevators with hydraulic systems, beginning with the future USS Doris Miller, or CVN-81, USNI News reported.
Trump has repeatedly criticized EMALS as "too complex" and "not as effective as steam catapults," according to Reuters.
But the order would reverse a technology path the US Navy has pursued for more than a decade. When the Navy selected EMALS in 2009, it said the system would lower overall lifecycle costs, require less maintenance than steam catapults and place less physical stress on carrier-based aircraft, per Reuters.
As of March 2026, the USS Gerald R. Ford had conducted 36,863 EMALS launches, according to Pentagon documents cited by Reuters.
General Atomics, the manufacturer of EMALS, has warned against changing course on the Doris Miller, saying nearly 50 percent of production related to the system has already been completed and that a switch now would create significant cost, schedule and integration risks, according to Reuters.
Zhang Junshe, a Chinese military affairs expert, told the Global Times on Sunday that the Ford-class carrier's aft-positioned island is not merely an aesthetic choice, but is closely tied to flight-deck efficiency and landing safety. "Moving the island farther aft creates more space around the catapults for aircraft parking and handling, helping shorten launch preparation time, while also reducing airflow disturbance during aircraft recovery," he said.
Relocating the island forward would not be a simple cosmetic adjustment, but a major redesign affecting weight distribution, buoyancy, flight-deck layout and aerodynamics, with significant implications for both cost and schedule, Zhang noted.
Song Zhongping, another Chinese military affairs expert, told the Global Times that Trump's demand is one thing, but turning it into an actual warship design is another.
"The first four Ford-class carriers have either entered service or are already in different stages of construction, leaving very little room for fundamental changes to their overall designs," Song said. Even the fifth and sixth ships - the future USS William J. Clinton, CVN-82, and USS George W. Bush, CVN-83 - would face considerable cost and engineering consequences if the Navy attempts to overturn their established technological architecture, he said.
The US Navy officially announced the names of CVN-82 and CVN-83 in January 2025, per the US Navy official website.
"There is an obvious gap between US President's political will and the engineering realities of aircraft-carrier construction," Song said.
Such proposed changes come as Ford-class construction timelines have already grown considerably compared with those of the preceding Nimitz class. The US Congressional Budget Office (CBO) said in April that Nimitz-class carriers typically took seven to eight years to build, while Ford-class ships are currently taking roughly 10 to 11 years. In a separate assessment released this month, the CBO estimated that future Ford-class carriers under the Navy's 2027 shipbuilding plan could cost about $22 billion apiece.
"Electromagnetic launch represents an advanced direction in aircraft-carrier catapult technology and has far greater development potential than traditional steam catapults," Song said. "If the US gives up electromagnetic catapults and returns to steam catapults, that would be a technological regression and a step backward."
Echoing Song, Zhang said electromagnetic catapults offer more precise control of launch energy and broader compatibility with different types of carrier-based aircraft, while requiring less shipboard space than steam systems with their extensive high-pressure piping.
"Replacing EMALS with steam catapults on a Ford-class carrier already designed around electromagnetic launch would not only represent a technological step backward, but could also turn an attempt to reduce risk into a new source of engineering and system-integration risk," Zhang said.
。 8 月 25 日消息，据在 macOS Tahoe 26.7 更新中发现的代码，苹果正在开发的智能家居中枢设备 HomeHub 将支持多用户配置文件，能够通过识别用户面容来自动切换不同账号。从代码信息来看，这款家居中枢能够针对不同家庭成员显示“个人内容（Personal Content）”，用户也可以通过设备的控制中心或“设置”App 手动选择自己的配置文件。由于该设备预计运行类似 tvOS 的系统，因此其控制中心和用户切换界面可能会与 Apple TV 比较相似。
B | 代码中还多次提到摄像头、环境感知以及身份验证。例如，当设备无法确认当前用户身份时，会提示用户在控制中心选择自己的个人资料；如果设备较长时间没有看到某位用户，则会要求其重新站到摄像头前进行验证。此外，部分提示信息显示，用户需要临时允许设备通过环境感知功能确认身份，才能访问个人内容。这些信息暗示，该家居中枢可能会结合摄像头和其他传感器判断房间内是否有人以及具体是哪位家庭成员，并根据识别结果自动切换配置文件。代码还确认苹果将推出两种版本的家居中枢，其中一种可以壁挂安装，另一种则配备扬声器底座。此前传闻称，该设备将采用约 7 英寸的方形屏幕，支持运行 App，并拥有带快速访问小组件的主屏幕。
C | 目前尚不清楚苹果最终会如何命名这款产品，但如果传闻属实，该产品将被命名为 HomeHub，最早可能在 9 月（下月）正式公布。
