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.
。 12月12日,国家统计局发布2024年粮食产量数据公告。数据显示,我省粮食产量达500.06亿斤,位居全国第十二;粮食单产为931.88斤/亩,位居全国第四、粮食主产省第二,亩产比全国平均水平高142.4斤;播种面积达5366.25万亩。
从全国来看,粮食总产量达到14130亿斤,同比增长1.6%,首次迈上1.4万亿斤新台阶。今年我省粮食产量继续稳定在500亿斤以上,表明我省粮食主产省的地位持续巩固。
毫不松懈稳面积。我省始终把粮食生产作为“三农”工作的头等大事,及时出台支持粮食生产一揽子政策,向农户发放玉米大豆生产者补贴、稻谷生产者补贴、耕地地力保护补贴资金84.1亿元,调动农民种粮积极性,今年全省粮食播种面积继续稳定在5300万亩以上,为夺取丰收奠定了坚实基础。
全力以赴降损失。今年汛期,我省局部地区降雨偏多,全省上下以汛为令,积极采取有力措施降低影响,第一时间筹措省级救灾资金1000万元、争取中央救灾资金1亿元,支持疏通沟渠、抢排积水、追施肥料、恢复生产。认真实施“一喷多促”项目,落实资金8310万元,组织喷施叶面肥、植物生长调节剂等肥料药剂877.9万亩,促进作物灾后恢复、生长发育、灌浆成熟和产量提升。
全力以赴提单产。我省指导辽西地区和排水条件较好地区等未受灾地区,切实加强中后期田间管理,提高单产水平,弥补受灾地区损失。同时,大力实施“藏粮于地、藏粮于技”各项举措,新建和改造提升高标准农田316万亩,实施黑土地保护工程1000万亩,耕地地力进一步提升。玉米、大豆单产提升工程项目县由2个增加到11个,阜新、朝阳等地涌现一批“吨粮田”,大豆300亩连片项目区实现亩产681.1斤,创造了东北地区大豆大面积实测高产纪录。此外,未受灾地块“以丰补歉”和众多工程项目的有力支撑,也为我省今年粮食单产水平继续稳定在较高水平创造了条件。
