Photo: VCGUS President Donald Trump's reported push to reshape the US Navy's next-generation aircraft carriers - from moving the island to abandoning electromagnetic catapults in favor of steam-powered systems - could impose heavy engineering, financial and schedule costs, Chinese military affairs experts said, warning of a widening gap between political preferences and the realities of building some of the world's most complex warships.
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.

IT之家 8 月 22 日消息,由北京市人民政府、中央广播电视总台等单位联合主办的第二届世界人形机器人运动会今天开幕。本次比赛将持续到 26 日,共设置 51 个项目、1300 多场比赛。

B | 今年竞技赛新增跳远、举重、拔河、乒乓球等高强度对抗项目。本届运动会正赛将于 8 月 22 日至 26 日在国家速滑馆“冰丝带”举行,将举行 51 个项目共 1301 场比赛,吸引 666 支队伍携 2056 台机器人参赛,竞赛项目、参赛队伍全面提质扩容。从报名情况来看,各路高手将云集赛场。本届赛事吸引了来自六大洲、16 个国家的 666 支队伍,共有 2056 台机器人同台竞技,队伍数量较首届增长 138%,机器人数量翻了两番。国际方面,美国、德国、日本等机器人传统强国赛队积极参与,巴西还集结了五支机器人足球世界杯队伍,组建起一支国家联队参赛。国内方面,157 家企业、200 所院校和科研机构的 641 支队伍、1975 台机器人齐聚赛场。国内第一梯队企业悉数到场,27 所 985 高校踊跃参赛,产学研用各方力量汇聚一堂。IT之家从官方介绍获悉,今年赛项从首届的 26 项增加至 51 项,其中竞技赛 30 项、场景赛 21 项;比赛场次从 487 场增至 1301 场。在竞技赛中,今年新增的跳远、举重、拔河、乒乓球等高强度对抗项目,都是对机器人大脑、小脑、本体结构以及核心零部件的极限考验。赛场上每多跳远 1 厘米、每多举起 1 公斤,都是工程师们对关节电机、减速器不断优化设计、精密加工、测试验证的结果。此外,田径场比拼将更加激烈,机器人足球比赛将实现带球跑动、大力抽射等技能提升,更有百支队伍上演“舞林争霸”。本届场景赛则将赛项延伸到真实环境,覆盖工业、酒店、家庭、物流等领域,并专门设置了灵巧手赛项。

C | 其中,灵巧手设有夹豆子、拧螺丝等 8 个“微操”赛项,上演指尖对决。

D | 相比去年场景赛机器人仅“一个人战斗”,本届升级为机器人两两同台比拼,进一步增加赛事的精彩程度和观赏性。
