Political preferences clash with warship building realities as Trump pushes costly Ford class carrier revamp: experts_我的网站
一 |
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.
。 自小球时代席卷联盟而来，就再也没有产生过一支王朝球队了，最后一支王朝球队已经是离我们十二年之久的四年豪夺两冠的迈阿密热火了。为什么会出现这样的情况呢？究其原因，还是在于一个“快”字，就像小球时代的要求一样，打法在于快，更多的进攻回合，要求每个位置都能跑能投。
二 | 也影响着现在的管理层都朝着这样的思路去建队，大家基本都有着一样的思路，就看谁在自由市场上做到“快准狠”，最终带来的结果就是建队快，拆队也快，要的是速成。所以从现如今NBA联盟各队组建阵容的思路，以及怎样的阵容会奏效，就很容易知道最终的冠军花落哪几家了。而经过休赛期的各种交易后，新赛季的夺冠热门也就显现出来了。 首先排名第一，最大的夺冠热门非休赛期引援最成功的费城76人莫属了，用身背“垃圾合同”，联盟背景板的保罗乔治，换来单打之年，甚至还没有到达生涯巅峰期的MVP杰伦布朗。以及不花费任何筹码在自由市场上拿下还是联盟前十五的历史第一人勒布朗詹姆斯。再加上替补上补强了安芬尼和波普。这一系列的操作直接让76人坐拥联盟最强豪华阵容，让其登上夺冠排行榜榜首。这样的阵容在历史第一人勒布朗詹姆斯的带领下，若没有伤病困扰，十有八九拿下26-27赛季的NBA年度冠军。 其次是排名第二的是，正在迅猛崛起的圣安东尼奥马刺队。虽然上个赛季在总决赛舞台上折戟，无功而返，但是经过上个赛的历练，让阵中的年轻天赋成长颇大。
三 | 再加上阵容中还有着历史第一天赋文班亚马，哈伯，卡斯尔等年轻翘楚，以及经过一个休赛期的成长，这才把马刺排到打败他们的尼克斯前面。请记住新赛季的马刺不容小觑，虽然很难击败76人，但冲出西部应该不难。 排名第三的是，俄克拉荷马雷霆。另一支阵容极其深厚的天赋异禀的年轻球队，阵容中有着连夺常规赛MVP的“历史第一碰瓷王”，还有切特和威廉姆斯这些年轻天赋，最主要的是雷霆有着联盟最深的阵容配置。上个赛季要不是受制于伤病，说实话马刺还真上不了总决赛舞台，也就没有尼克斯和布伦森夺冠的事了。新赛季的西部绝对是马刺和雷霆两强争夺的局 面，雷霆能否复仇马刺，就要看切特能否克服心魔。 最后给到排名第四的是，卫冕冠军纽约尼克斯。这也是一支阵容深厚的球队。可能很多球迷会问，为什么刚刚夺冠的球队，只能排到区区第四名。
四 | 这是因为前面三支球队，无论天赋还是实力都要强过这支尼克斯，况且上个赛季对文班起到一定限制的米奇还走了，来了一个大漏洞德拉蒙德这个“糙汉子”。说实话要不是上个赛季运气好夺了冠，我都想把休赛期进行大换血的湖人了。所以说，给个排名也是对卫冕冠军的一种尊重，新赛季有76人在，尼克斯休想冲出东部。
五 | 然后再看看，拥有现联盟第一人东契奇的湖人为什么不足以排进争冠榜排名前列，说白了还是受限于天赋二字，看看湖人休赛期的操作，只是补充了一些功能性的角色球员，这些人在季后赛能给到东契奇的帮助真的有限，而且二当家里夫斯打不了关键比赛是个事实。真的把一些没有天赋的球员拼凑在一起，要夺冠真的是痴人说梦。
六 | 再一个是坐拥联盟第二人约基奇的丹佛掘金队，休赛期毫无作为，而且几个核心都受伤病侵袭，已经退出了争冠讨论，说实话新赛季掘金也就是常规赛打打漂亮比赛了。真的又是浪费约基奇天赋的一个赛季。
