当地时间28日,美国总统特朗普在驻日美军横须贺海军基地面向美国军人发表讲话时表示,将颁布命令把航母上昂贵的电磁弹射器改为蒸汽弹射器。
据俄罗斯卫星通讯社报道,美国总统对于在电磁弹射上花巨资感到不满。他补充说,“这是在我之前发生的,我们将花9亿美元用于这些疯狂的电动弹射器。而我要问:蒸汽有什么不行的?”
特朗普在美军“黄蜂”号两栖攻击舰上说,尽管专家们宣称电磁弹射启动更快,不需要加速度。但他指出,“我们不需要这种加速度,因为我们每隔2分钟只能发射一次飞机。”

据了解,发射弹射器在航母上用于为飞机起飞时加速。目前绝大多数航母都是用蒸汽弹射器。

电磁飞机弹射系统(Electromagnetic Aircraft Launch System)由通用原子公司(General Atomics)开发,用于取代美国航空母舰上的蒸汽弹射器。美国海军尚未正式投入使用该新系统。
特朗普说:“蒸气弹射系统完美地用了65年,但他们为了这个疯狂的电磁弹射系统,超支9亿美元,他们要表现,下一代、下一代,我们都要创新,但太离谱了。”
特朗普强调,“我们花大笔钱发展电磁弹射系统,但没人知道这种系统在恶劣环境下会是什么状况,我想我会下令,我们建造新航母时,使用蒸气弹射系统。”
据美联社消息,28日上午,作为“日本国宾”的特朗普在安倍的陪同下,登上日本海上自卫队“出云”级直升机驱逐舰“加贺”号。随后,两国首脑在日本自卫队员和美国海军陆战队士兵面前发表了演讲。
28日是特朗普此次访日之行的最后一天,一大早他就通过推特公开了自己这一天的主要行程。“今天上午我会在日本停留两站,去看望我们伟大的军队,然后在阿拉斯加稍作停留就回华盛顿了。我和安倍首相的会谈非常顺利,能和日本新天皇和皇后见面是我莫大的荣幸。”


Trump: Will issue an order to change the electromagnetic ejection of the aircraft carrier to steam ejection
May 28, 2019 16:11 Observer Network

On the 28th local time, US President Trump said in a speech to US military personnel at the US Navy base in Yokosuka, Japan, that he would issue an order to change the expensive electromagnetic catapult on the aircraft carrier to a steam catapult.

According to the Russian satellite news agency, the US president is dissatisfied with the huge investment in electromagnetic bombing. He added, "This happened before me. We will spend $900 million on these crazy electric catapults. And I have to ask: What is wrong with steam?"

Trump said on the US military "Hornet" amphibious assault ship, although experts claim that electromagnetic ejection starts faster and does not require acceleration. But he pointed out, "We don't need this acceleration because we can only fire one plane every 2 minutes."

It is understood that the launch catapult is used on the aircraft carrier to accelerate when the aircraft takes off. At present, most aircraft carriers use steam catapults.

The Electromagnetic Aircraft Launch System was developed by General Atomics to replace the steam catapult on the US aircraft carrier. The US Navy has not officially put into use the new system.

Trump said: "The vapor ejection system has been used perfectly for 65 years, but they have over 900 million dollars for this crazy electromagnetic ejection system. They want to show that the next generation, the next generation, we must innovate, but it is too outrageous. ""

Trump stressed, "We spend a lot of money to develop the electromagnetic ejection system, but no one knows what the system will be in a harsh environment. I think I will order that we use a vapor ejection system when we build a new aircraft carrier."

According to the Associated Press, on the morning of the 28th, Trump, as a "Japanese national guest", accompanied by Abe, boarded the "Kaga" helicopter destroyer "Kaga" of the Japanese Maritime Self-Defense Force. Subsequently, the heads of the two countries delivered speeches in front of the Japanese Self-Defense Forces and the US Marine Corps soldiers.

On the 28th, the last day of Trump’s visit to Japan, he announced his main day of the day through Twitter. "I will stop at Japan for two stops this morning, visit our great army, and then return to Washington after a short stay in Alaska. My meeting with Prime Minister Abe is very smooth. It is my great to meet with the Japanese New Emperor and Empress. with pleasure."

Trump vows a return to steam-powered aircraft carrier catapults in Memorial Day speech in Japan

2:36 a.m.

President Trump has been known to fixate on certain details, like fabrics for his hotels and the aesthetics of his border wall, and in a speech to U.S. service members in Japan on Tuesday, he hit on another of his preoccupations: aircraft carrier catapults. After wishing about 800 members of the U.S. Navy's 7th fleet gathered on the USS Wasp "a very happy Memorial Day," Trump asked the friendly audience if they prefer steam-powered or electromagnetic aircraft catapults, apparently announcing he will order the Navy to revert to steam-powered catapults in future aircraft carrier orders.


Trump has criticized the new Electromagnetic Aircraft Launch System (EMALS) several times since taking office, saying at various times that "you have to go to MIT to figure out how this damn thing works," that "you have to be Albert Einstein to really work it properly," and "it's like when you get a new car and you have to be a computer genius to fix your seat." ("You sort of have to be Albert Einstein to run the nuclear power plants that we have here as well, but we're doing that very well," Capt. Pat Hannifi, commander of the aircraft carrier USS Ronald Reagan, told Trump last Thanksgiving.)
EMALS, installed so far only on the USS Gerald R. Ford, is over-budget and behind schedule. "It's not clear how the president became interested in this somewhat obscure military technology issue," The Washington Post noted in November, but the Navy says EMALS takes up less space, increases the variety of aircraft that can be launched, will launch them more quickly with fewer operators and less wear on aircraft, and will cost significantly less than steam over time.
"EMALS is a poster child for immature technologies sent to the field too soon," Kyle Mizokami explained in Popular Science in May 2017. "That said, by all accounts the principles behind it are sound," its "problems will eventually be worked out," and the president "micromanaging complex engineering programs is a bad idea."

Donald Trump Plans to Use Traditional Steam Catapults on U.S. Aircraft Carriers
By Dan Cancian On 5/28/19 at 7:39 AM EDT




Sanders Avoids Explaining Why Trump Appointed 'Ill Equipped' Rex Tillerson As Secretary Of State

U.S.
President Donald Trump has announced plans to overhaul what he has described as the “wrong” design of U.S. aircraft carriers.
Speaking to troops stationed in Japan, Trump said he would favor the use of traditional steam-powered catapults instead of electromagnetic systems on American warships.
Ford’s Electromagnetic Aircraft Launch System (EMALS) is replacing traditional steam catapults as the preferred way to launch aircrafts off navy ships. Trump, however, suggested there was no way to know whether the more modern system would work efficiently during wartime.
“We’re spending all that money on electric and nobody knows what it’s going to be like in bad conditions," he told sailors and Marines on the USS Wasp, as reported by Bloomberg.
"So I think I’m going to put an order—when we build a new aircraft carrier, we’re going to use steam."
The president also polled the aircraft carrier’s personnel over their preferences and Bloomberg reported the cheer for traditional catapults were considerably louder than for EMALS.
Trump has been a vocal critic of Ford’s system and told the personnel the technical innovation that came with EMALS was offset by its huge costs.
“Steam’s only worked for about 65 years perfectly,” he added.
“And I won’t tell you this because it’s before my time by a little bit, but they have a $900 million cost overrun on this crazy electric catapult.
“They want to show—next, next, next. And we all want innovation, but it’s too much.”
In January this year, Senator Tim Kaine (D-VA) confirmed the U.S. Navy had informed lawmakers it intended to purchase two Ford-class aircraft carriers.
Kaine, a member of the Senate Armed Services Committe e, said officials believed the move could save billions of dollars for taxpayers.
“This smart move will save taxpayer dollars and help ensure the shipyards can maintain a skilled workforce to get the job done,” he said in a statement at the time, as per Reuters.
The Trump administration has looked to expand the size of the fleet over the last three years. In 2016, the Navy said it had upgraded its force structure goal to 355 ships, from a previous target of 308.
Meanwhile, Trump said he was “not personally bothered” by the short-range missile tests that North Korea carried out earlier this month.
Speaking alongside Japanese Prime Minister Shinzo Abe on Monday, the president said he was not concerned by Pyongyang’s tests.

His stance was not echoed by Abe, who stated that the tests were a matter of “great regret” and had violated U.N. Security Council resolutions.
Trump’s visit to the Yokosuka naval base, the largest U.S. naval installation overseas, was the final stop on the president’s four-day trip to Japan.

Trump Wants ‘Goddamned Steam,’ Not Digital Catapults on Aircraft Carriers

“You have to be Albert Einstein to figure it out.”
Adrienne LaFrance May 11, 2017

lead_720_405.jpg

Navy officials were “blindsided” on Thursday, a spokesman told me, by President Donald Trump’s suggestion that he has convinced the Navy to abandon a long-planned digital launching system in favor of steam on its newest aircraft carrier.

In a wide-ranging interview with Time magazine, Trump described his disgust with the catapult system known as Electro-Magnetic Aircraft Launch System, nicknamed EMALS, aboard the USS Gerald R. Ford. (Time has published only excerpts from the interview, not a full transcript.) The president described wanting to scrap EMALS, a key technological upgrade at the center of the multibillion-dollar carrier project, and return to steam.
I said, “You don’t use steam anymore for catapult?” “No sir.” I said, “Ah, how is it working?” “Sir, not good. Not good. Doesn’t have the power. You know the steam is just brutal. You see that sucker going and steam’s going all over the place, there’s planes thrown in the air.”
It sounded bad to me. Digital. They have digital. What is digital? And it’s very complicated, you have to be Albert Einstein to figure it out. And I said—and now they want to buy more aircraft carriers. I said, “What system are you going to be—” “Sir, we’re staying with digital.” I said, “No you’re not. You going to goddamned steam, the digital costs hundreds of millions of dollars more money and it’s no good.”​
What is digital? To answer the president’s question without getting into too many 0s and 1s, “digital” means using a computer to make something happen. You know, the same sort of machine that connects us all to the cyber. Are you still with me, or should we get Einstein over here? (I mean, Einstein has done an amazing job and is being recognized more and more.) EMALS isn’t just computer-based but uses a linear induction motor. That motor—which uses electric currents to activate a magnetic core—propels a carriage down a track to launch an aircraft, rather than using a steam piston drive to pull the aircraft.

Despite Trump’s technological leanings—he’s TV obsessed, he was a semi-early adopter of the web, and he has a preternatural sense for Twitter drama—his question about “digital” calls to mind his apparent cluelessness about cyber security.
It’s not that EMALS has been a smashing success. Cost and schedule overruns have given the Navy carrier project a reputation for being "one of the most spectacular acquisition debacles in recent memory,” as Senator John McCain, the Arizona Republican, put it in 2015. “And that is saying something.” The construction of three Ford-class aircraft carriers has swelled from $27 billion to $36 billion in the last 10 years.




But the problems with the Ford-class carrier program are more organizational than technological—a common theme among infrastructural megaprojects. McCain blamed “misalignment of accountability and responsibility in our defense acquisition system” and the vast bureaucracy of defense acquisition systems, which span multiple offices and program managers.

Trump seems to have seized on the project’s bad reputation without appreciating—or at least without clearly articulating—the complexities of moving from steam to digital.
The steam-powered catapult systems that are being replaced have been used to launch airplanes from U.S. carriers for some six decades now. Not only are steam systems harder to maintain than electrical ones; they have a lower upper-limit during combat—meaning electrical systems can launch more aircraft in a shorter amount of time. Electrical systems can also better handle smaller aircrafts and drones compared with steam. Steam systems also put more stress on airframes, and make them more prone to corrosion. Not only that, but carriers themselves are exceedingly vulnerable to attack—meaning outfitting them with the modern defense systems is a priority.
The goal for the upgraded system is to use carriers to create “an operational honeycomb of interconnected forces with reach, range and lethality against air, sea, space, and land-based targets,” as Robbin Laird and Ed Timperlake wrote for the website Breaking Defense in 2015.

Despite some high-profile failures in early testing, EMALS is now nearly complete and ready for sea trials. It represents one of three major initiatives in the Navy’s push to go upgrade its weapons systems for the digital era.
Trump’s insistence on steam is perhaps bewildering, but also consistent with some of his other views about technology. After all, the president has repeatedly talked about returning to America’s golden age of manufacturing—an idea that’s laughable, if regrettable, to anyone who has looked closely at the forces driving the global economy. Among them: the rise of automation, which promises to dramatically transform the way humans work across multiple industries, and which Trump has all but ignored.
Then again, for a man who is clearly concerned with hugeness, you’d think Trump might appreciate EMALS: In working order, the system can launch anything from the sleekest drone to the sturdiest F-35, and it blasts through the technological limits imposed by steam. Trump has demonstrated a fondness for super carriers, and has said he plans to increase the U.S. fleet from 10 to 12.

He hasn’t, however, indicated how he plans to pay for that. The cost of a single new, Ford-class carrier—about $11 billion without cost overruns—would eat up nearly 20 percent of Trump’s proposed defense budget increase, Reuters reported in March.
The Navy says it is scrambling to figure out how to address the president’s concerns. A spokesman said it will issue a statement on Thursday afternoon, and figure out talking points for Naval leaders should the question come up at public events.
In the meantime, Trump might do well to worry more about the signature infrastructure promise of his own campaign, than a near-complete military project he doesn’t seem to understand.

Trump Was Right: The Navy's 'Digital' Catapult Really Is An Expensive Mess
Jared Keller
January 31, 2019 at 10:14 AM

Military Tech


When President Donald Trump railed against the $13 billion USS Gerald R. Ford aircraft carrier's electromagnetic catapult as no match for "goddamned" steam, he may have been on to something — even if he didn't know it at the time.
According to the latest assessment of the next-generation carrier from the Pentagon's operational testing and evaluation arm, set for public release this week and obtained early by Bloomberg News' Tony Capaccio, the Ford's Electromagnetic Aircraft Launching System (EMALS) experienced 20 distinct failures during sea trials in the last year.
The evaluation indicates that that the Ford experience 10 "critical failures" out of 747 at-sea jet launches and an additional 10 "operational mission failures' during 763 landing attempts, And while a Navy spokesman told Bloomberg that those launch and landing attempts are "an insufficient number of events from which to draw conclusions with respect to reliability," the Pentagon's director of operational testing suspects otherwise. From Bloomberg:
The Ford "will probably not achieve" its sortie rate requirement because of "unrealistic assumptions" that "ignore the effects of weather, aircraft emergencies, ship maneuvers and current air-wing composition on flight operations," Robert Behler, the Pentagon's director of operational testing, said in his assessment of the carrier, obtained by Bloomberg News.
...
In a memo to Acting Defense Secretary Patrick Shanahan transmitting the annual report, Behler highlighted the Ford's problems, saying that although "improvements have occurred, poor and unknown reliability continues to plague the ship and key systems."

These problems are far from new. The Pentagon's previous testing and evaluation assessment for 2017 detailed significant reliability issues ranging from "excessive airframe stress" to an inability to electrically isolate the catapult's complicated power systems in order to conduct maintenance and repairs without halting operations.
Even worse, the Pentagon noted at the time that the EMALs only had a 70 percent chance of completing a day of sustained ongoing sorties and 9 percent chance of completing a four-day surge, the kind of sustained operations that U.S. personnel downrange have come to rely on.
This is, well, a laugh riot considering that Trump, despite his propensity to avoid micromanaging the Pentagon like his predecessor, singled out the EMALs system as a high-tech boondoggle during an interview with Time magazine in 2017:
"You know the catapult is quite important. So I said, 'What is this?' 'Sir, this is our digital catapult system.' He said, 'Well, we're going to this because we wanted to keep up with modern [technology].' I said, 'You don't use steam anymore for catapult?' 'No sir.' I said, 'Ah, how is it working?' 'Sir, not good. Not good. Doesn't have the power. You know the steam is just brutal. You see that sucker going, and steam's going all over the place, there's planes thrown in the air.'
"It sounded bad to me. Digital. They have digital. What is digital? And it's very complicated. You have to be Albert Einstein to figure it out. And I said — and now they want to buy more aircraft carriers. I said, 'What system are you going to be' — 'Sir, we're staying with digital.' I said, 'No you're not. You going to goddamned steam. The digital costs hundreds of millions of dollars more money and it's no good.'"

Speaking of hundreds of millions fo dollars: Bloomberg notes that the Navy is poised to announce a massive contract with Huntington Ingalls to build the service's next two Ford-class carriers at the same time. Hey, even a broken clock is right twice a day.

Is Trump right to insist on old steam catapult technology for the newest USN aircraft carriers?

No. He’s wrong about this one. The tech of EMALS is far superior to the old steam catapult. The steam catapult might be cheaper and more reliable right now because this is the first time anyone has ever tried to use EMALS on an aircraft carrier. That always happens when something is brand new. They’ll work the kinks out of it, just as they worked the kinks out of the V-22 and the F-22.
Trump is not well known for his interest in science. I’m not sure if he used the word “digital” or if someone else used it first when speaking to him, but “digital” is not what EMALS is about. That just shows his lack of knowledge about this issue. Trump said it’s so complicated that you have to be Einstein to figure it out, but the beauty of electromagnetic launch is that it’s silly simple. There are so few moving parts that it’s nearly impossible to break it. It has growing pains now, but once they’re worked out, the Navy will be glad to have it.
Ultimately, EMALS will give the Navy much greater capability, will be more reliable, and will eventually save money.
EDIT: I just got off the phone with an ex-coworker. He’s 90 years old now and remembers when the Navy was going to jet aircraft and CATOBAR carriers. We talked about this very subject and he started laughing…
It was 10 times worse when we went from piston props to jets. There were guys who thought the jets were too complicated, while the engineers tried to explain that jets are actually more reliable than piston-engine props. The ‘old’ guys were saying “there’s not even enough room for the jets to take off.” The engineers said, “that’s OK, we’re going to hook the jets up to a catapult and fling them into the air.” You can imagine the reaction. We had already experimented with arresting cables, but the old guys were convinced it wouldn’t work with jets.
The steam catapult is a marvel of naval aviation, but it has had its day. In a couple of decades at the most, there probably won’t be any still operating. That’s just progress. The P-51 was an outstanding fighting aircraft, but there’s a reason we don’t fly them in combat any more. This is no disrespect to those old planes and the steam catapult… the old always gives way to the new, eventually.
China and Russia are already stretching their legs with larger carriers. Within a few years maybe they’ll be operating CATOBAR carriers too. When that happens, the USA is going to need to already be one step up on the ladder, and the EMALS is one way to do that. The primary advantages of the EMALS are faster operation and less “down” time, but the biggest is the ability to launch a wider weight range. It can launch an F-35 and then a minute later launch a small drone. It takes up less space and weight on the ship, too.

The naval technologies of bankrupted beggar USA will fallback all the way to WW2 standard, this is going to be a rapid failure and regression.

Stupid Dotard President is a big factor now. Set to crash and destroy USA.
 
By the time Chinese using 8G and still this US 6G not able to work. They are so disadvantaged and lagging too far now. Too broke to get back on feet. 5G enough to make USA fall worse the USSR. They will become history.
 
PLA now want to UPGRADE their SKI-JUMP Liao Ning Carrier to Electromagnetic Catapult Launcher same as their #003 carrier which is at final assembly on the open-dock-yard. Dotard said Electromagnetic Catapult Launcher needed Einstein Brains to operate! How fucking STUPID! While Chow Ang Moh got full of Marijuana Weed Smoking idiots on their warships, Chinese are all smarter by 10X. Dotard said his Electromagnetic Catapult Launchers EXCEEDED BUDGET by huge sum and delayed and full of problems - that is his idiots cannot do things correctly and ripped off Pentagon & Tax Payers' $$$! Fucking failure! MAGA!

Steam Catapult emits steam and FREEZES INTO SLIPPERY ICE on the flight deck in winter sea. Best part yet, it freezes SALT ICE on the deck & warplanes & EVERY DAMN THINGS ELSE - MOSTLY ARE BILLION DOLLAR EXPENSIVE EQUIPMENT! And the Navy had to do extra fucking works to DE-ICE EVERYTHING! Ice frozen on wing will cause warplanes to CRASH INTO SEA! The steam catapult kept spewing steam to mix with cold wind & salt of the sea and stuck to make a layer of slippery ice, you cannot even walk safely without fucking accident. You deck vehicles & jets tires slips and gets accidents, may crash into fucking sea!

Dotard == IDIOT!

关于特朗普近年来多次声称要“枪毙”航母电磁弹射器这件事,昨天本站丙探的文章已经做过一定的分析。不过咱们开个脑洞,既然美国赶上了这么一位性格独特的总统,如果脾气真的上来,说什么也要推动改回蒸弹;甚至不惜动用总统权力,再次使用“紧急状态”,满地打滚非要海军换用蒸汽弹射器,那该如何是好呢?
2566-hxvzhtf8872153.jpg

Make Airwing Grounded Again ?
有道是办法总比困难多,先不提已经交付美国海军服役的CVN-78“福特”和刚刚完成舰岛吊装、即将在今年下半年下水的CVN-79“肯尼迪”,该型舰第三艘CVN-80“企业”在2017年进行了钢板切割仪式,明年将正式入坞建造。
0101-hxvzhtf8872227.jpg

当地时间5月29日,正在纽波特纽斯建造的CVN-79“肯尼迪”吊装舰岛
按预计,“企业”将会在2025年下水,按照这个进度,哪怕特朗普成功做到了第二任期(2024年卸任),等到了该舰进入安装弹射器的工序时,白宫也将换了主人。而预计2023年入坞建造的“福特”级四号舰,则更难以受到特朗普的影响。
cdb2-hxvzhtf8872288.jpg

2017年8月24日,CVN-80“企业”举行钢板切割仪式,该舰计划于2020年入坞建造
那么如果特朗普不仅要求将来建造的“福特”级换回蒸汽弹射器和液压拦阻系统,还要求现有的该型舰统统回厂拆掉电弹、换回蒸弹,那该怎么办呢?在这之前我们先来回头看一看,美国海军历史上航空母舰的重大改装项目,当属“埃塞克斯”级的SCB-27、SCB-125和“中途岛”级的SCB-110。
013b-hxvzhtf8872348.jpg

38d5-hxvzhtf8872441.jpg

想起了当年丙探发射的航母改造家系列卫星。。。。。。
其中以甲板上的飞机弹射器为核心的是SCB-27项目(SCB-27A加装的是H8液压弹射器,SCB-27C则加装C11蒸汽弹射器和起飞位燃气偏流板),这些接受改装的“埃塞克斯”级,其改装工期均在两年上下。
7b12-hxvzhtf8872511.jpg

初始、接受SCB-27与SCB-125改装后各状态的“埃塞克斯”级航母
尽管SCB-27折腾这么久,是因为还涉及到了很多弹射器之外的改装项目、如甲板、舰岛、燃油储备设施和升降机等;但高度复杂的现代航母,其系统复杂程度与施工难度也远非当年的二战航母所能相比(SCB-27所改装的“埃塞克斯”级和SCB-110所改装的“中途岛”级,均仅有两台飞机弹射器),若决定进行改装,“福特”级需更换4具弹射器以及其附属设备,同时还要更换用于飞机着舰的拦阻系统,其工程量比起当年的SCB-27可以说是只多不少。
对这种牵一发而动全身的改装项目,必定得严谨论证、细致设计,而如此规模的改装项目,论证与设计工作必然不是一两年就可完成的。所以对美国海军来说,使用这个“拖”字诀,就能一方面对特朗普“假装真忠诚”,一方面最大限度降低总统瞎指挥对装备建设的干扰。

电磁弹射器(上)与蒸汽弹射器(下)仅所需的甲板开槽形状就有所不同
b12d-hxvzhtf8872717.jpg

而它们所需的甲板下设备差别则更加巨大(图为蒸汽弹射器示意图)
之所以要先替美帝合计一番这个,是因为笔者此前经常能在网上见到很多网友猜想:中国现有的两艘滑跃起飞航母,能不能“铲平”了滑跃甲板改装弹射器呢?还有的根据“电磁弹射器也可以做成弯的”进一步联想,可不可以把滑跃和弹射相结合呢?
e954-hxvzhtf8872775.jpg

类似脑洞还有直接把舰岛“暴力压缩”的
辽宁舰的续建和首艘国产航母的建造,在短时间内为我军提供了较为可靠也相对较为可观的航母作战力量。但囿于源自苏联的原始设计,这两艘航空母舰只能说较好地解决了中国航母的有无问题。好在近年来的歼-15弹射起飞验证机与正在建造当中的第二艘国产航母,标志着人民海军在航母建设上最终选择了弹射起飞的道路。
e599-hxvzhtf8872823.jpg

人民海军最终选择了弹射起飞作为航母发展方向
早在辽宁舰开始续建那当口,就有许多网友猜测该舰是否会加装飞机弹射器,而在续建工程进入中后期时,甲板上一排普通工棚又因为位置过于“恰当”,而给了网友们无限的遐想空间。但对航母尚处在摸索阶段的人民海军,在现有装备基础上先建设人才培养体系和形成初步的战斗力,显然是更重要的事情。

当年甲板上这两排工棚,引起多少网友浮想联翩……
前文说到,中国已经选择了弹射起飞的航母发展道路,那么在未来10年当中,采用电磁弹射器的多艘国产航母就将加入人民海军战斗序列。而此时两艘“末代1143”仍然处于壮年期,对于一支要建立足够规模的远洋海军来说,同时存在两种起飞方式和舰载机规格迥异的航空母舰自然非常奇怪,而提前退役这两艘巨舰——特别是全新建造的首艘国产航母,在成本上又并非能够轻松承受。

把俩滑跃航母打包卖了,就跟把现代级返销给毛子的想法一样,都是好日子过几天忘了自己姓啥那种的
比起通常使用寿命在20多年上下的驱护舰艇,现代航母作为一种高技术、高集成度的大型水面作战舰艇,其使用寿命一般都较长。1975年服役的“尼米兹”级核动力航空母舰首舰CVN-68“尼米兹”,若按照计划在2024年由CVN-79“肯尼迪”替换,其服役年限将达49年。而两型常规动力航空母舰的代表CV-41“中途岛”和CV-63“小鹰”的服役年限则为47年和48年,这说明战后的大型航空母舰在“以造代修”、“以造代改”上的成本越来越高昂。

CV-63“小鹰”于2009年正式退役,服役长达48年
那么,如果在合适的时间将两艘滑跃起飞的航母进行大规模改装,就其工程周期而言,可以说与“中途岛”级的SCB-110相类似(巧的是排水量也类似)。考虑到辽宁舰本身就一直在中国航母工程发展中担负着验证的角色,在改装中结合当时出现的一些新技术再次进行验证也有可能。
尽管这两艘“末代1143”的原始设计方案源自苏联,但与136“杭州”舰的改装不同的是,辽宁舰本身是由我方自行续建完成的,并且通过自行建造了首艘国产航母而进一步“知其所以然”,所以在工程方面的了解程度相对较高;同时航空母舰这种级别的重要舰艇,其改装方案的制定,也不会像改装引俄驱逐舰那样周期相对较短。

经历了自主续建和自主建造的辽宁舰和首艘国产航母,在改装工程的制定和设计上,将更加科学和严谨(图片来源见水印)
而在此前我们曾多次探讨过,对于一个大国来说,具备两艘航母可以说“在大多数时候有航母”,三艘航母才能保证“在任何时候都有航母”。一方面,人民海军的确需要考虑统一未来的航母规格和操作习惯,而另一方面,也需要保证航母的总体战斗力不因改装施工而受太大影响;笔者据此推断,未来当采用弹射起飞的国产航母数量超过滑跃起飞航母,并稳定形成战斗力的那一天,这两艘仍处于壮年期的“功臣航母”,可能就将迎来它们脱胎换骨的时候了。

When Trump wants to cut electromagnetic bombs, the Liaoning ship hopes to "shovel flat" to slide the deck.
When Trump wants to cut electromagnetic bombs, the Liaoning ship hopes to "shovel flat" to slide the deck.

Author's signature: Yankee Frame Station

Regarding the fact that Trump has repeatedly claimed to "shoot" the aircraft carrier electromagnetic catapult in recent years, the article on the site's C probe has already done some analysis. But let's open a hole. Since the United States has caught up with such a unique president, if the temper really comes up, what should be said to promote the change back to the steam bomb; even if it does not hesitate to use the presidential power, use the "emergency" again, full If the ground rolls and the Navy wants to switch to a steam catapult, how can it be good?

Make Airwing Grounded Again ?

There is always a way to do more than the difficulties. First of all, the CVN-78 "Ford" that has been delivered to the US Navy and the CVN-79 "Kennedy" that has just completed the ship hoisting and will be launched in the second half of this year will be mentioned. The CVN-80 "Enterprise" carried out a steel plate cutting ceremony in 2017 and will be officially docked next year.

CVN-79 "Kennedy" hoisting ship island being built in Newport News on May 29, local time

According to the expectation, the "enterprise" will be launched in 2025. According to this progress, even if Trump succeeded in the second term (unloading in 2024), the White House will be replaced when the ship enters the process of installing the catapult. the host. The "Ford" class 4 ship, which is expected to be docked in 2023, is even more difficult to be affected by Trump.

On August 24, 2017, CVN-80 "Enterprise" held a steel plate cutting ceremony. The ship is scheduled to be docked in 2020.

Then, if Trump not only asks for the future conversion of the "Ford" class to return to the steam catapult and hydraulic arresting system, but also requires the existing ship to return to the factory to remove the electric bomb and exchange it for the steam bomb, what should I do? ? Before we go back and look at it, the major modification projects of the USS in the history of the US Navy are the SCB-27, SCB-125 and the Midway Island SCB-110 of the "Essex" class.

I remembered the series of satellites of the aircraft carrier transformation launched by the Detective. . . . . .

The center of the aircraft catapult on the deck is the SCB-27 project (the SCB-27A is equipped with an H8 hydraulic catapult, and the SCB-27C is equipped with a C11 steam catapult and a take-off gas deflector). The "Essex" class has a modification period of two years.

Initially, accepting the "Essex" class aircraft carrier in various states after SCB-27 and SCB-125 modification

Although SCB-27 has been tossing for so long, it is also involved in many conversion projects other than catapults, such as decks, islands, fuel storage facilities and elevators; but the highly complex modern aircraft carrier, its system complexity and construction difficulty Far from the World War II aircraft carrier of the year (the "Essex" class modified by SCB-27 and the "Middle Island" class modified by SCB-110, only two aircraft catapults), if decided Modification, "Ford" class needs to replace 4 catapults and its ancillary equipment, but also to replace the blocking system used for aircraft landing, the engineering volume can be said to be much more than the SCB-27.

This kind of transformation project, which is all about the whole body, must be rigorously demonstrated and meticulously designed. For such a large-scale modification project, the demonstration and design work must not be completed in one or two years. Therefore, for the US Navy, using this "drag" word, on the one hand, Trump "pretends true loyalty", on the one hand, minimizes the interference of the president's command and command on equipment construction.

The electromagnetic ejector (top) and the steam ejector (bottom) differ only in the required deck slot shape.

And the difference in the equipment they need under the deck is even greater (the picture shows the steam catapult)

The reason why I have to share this for the US emperor is because I have often seen many netizens guessing on the Internet: China’s two existing skiing aircraft carriers can "shovel" the slide deck rebuild catapult What? There are further associations based on the fact that "electromagnetic catapults can also be made into bends". Can you combine slipping and ejection?

Similar to the brain hole, there is also a direct compression of the island.

The continued construction of the Liaoning ship and the construction of the first domestic aircraft carrier provided our military with a relatively reliable and relatively considerable aircraft combat force in a short period of time. However, due to the original design originating from the Soviet Union, the two aircraft carriers can only say that they have better solved the problem of the Chinese aircraft carrier. Fortunately, in recent years, the J-15 ejection launcher and the second domestic aircraft carrier under construction indicate that the People’s Navy has finally chosen the path of catapult takeoff in the construction of the aircraft carrier.

The People’s Navy finally chose to take off and take off as the development direction of the aircraft carrier.

As early as the Liaoning ship began to build the mouth, there were many netizens who speculated whether the ship would be equipped with aircraft catapults. When the continuous construction project entered the middle and late stages, the row of ordinary work sheds on the deck was too "appropriate". Give netizens unlimited space for imagination. However, it is obviously more important for the People’s Navy, which is still at the stage of exploration, to build a talent training system and form initial combat effectiveness on the basis of existing equipment.

In the two sheds on the deck of the year, how many netizens thought about it...

As mentioned above, China has chosen the development path of the aircraft carrier for the take-off. In the next 10 years, many domestic aircraft carriers using electromagnetic catapults will join the People’s Navy battle sequence. At this time, the two "last generation 1143" are still in their prime. For an ocean-going navy with a sufficient scale to be established, there are two types of aircraft carriers with different take-off modes and different carrier-type aircraft. It is very strange, and they are retired in advance. The huge ship, especially the newly built first domestic aircraft carrier, is not affordable enough.

Putting the two skid carriers in the same package, just like the idea of returning the modern class to Maozi, it’s a good day to forget the last name.

Modern aircraft carriers, as a high-tech, highly integrated large surface combat warship, generally have a longer service life than a conventional warship that has a service life of more than 20 years. The first ship of the Nimitz-class nuclear-powered aircraft carrier, the CVN-68 "Nimitz", which was commissioned in 1975, will be replaced by CVN-79 "Kennedy" in 2024, and its service life will be 49 years. The representatives of the two types of conventional power aircraft carriers CV-41 "Mito Island" and CV-63 "Kitty Hawk" have a service life of 47 years and 48 years, which shows that the large aircraft carrier after the war is "made for repair", " The cost of making a change is getting higher and higher.

CV-63 "Kitty Hawk" officially retired in 2009 and served for 48 years.

Then, if the two aircrafts that take off on a large scale are modified at a suitable time, the engineering cycle can be said to be similar to the SCB-110 of the Midway Island (the coincidence is that the displacement is similar). Considering that the Liaoning ship itself has been playing a verification role in the development of the Chinese aircraft carrier project, it is also possible to verify it again in combination with some new technologies that appeared at that time.

Although the original design of the two "last 1143" originated from the Soviet Union, unlike the modification of the 136 "Hangzhou" ship, the Liaoning ship itself was built by ourselves and was built by ourselves. The aircraft carrier is further "knowing why", so the level of understanding in engineering is relatively high; at the same time, the aircraft of this class of aircraft carrier, the modification plan of the aircraft will not be as short as the modification of the Russian destroyer.

The Liaoning ship and the first domestic aircraft carrier that have undergone independent construction and self-construction will be more scientific and rigorous in the formulation and design of the conversion project (see the watermark for the source of the picture)

Previously, we have discussed many times. For a big country, having two aircraft carriers can be said to "have aircraft carriers most of the time", and three aircraft carriers can guarantee "the aircraft carrier at all times." On the one hand, the People's Navy does need to consider the future of aircraft carrier specifications and operating habits. On the other hand, it is also necessary to ensure that the overall combat effectiveness of the aircraft carrier is not greatly affected by the modification; the author infers that in the future, when taking off with a catapult On the day when the number of domestic aircraft carriers surpassed the skid take-off aircraft carrier and stabilized the formation of combat power, the two "fighting aircraft carriers" still in their prime, may soon be ushered in their reincarnation.

Are you flattered, are you comfortable?

电磁弹射下马!纯属蒙钱?200亿打水漂,5名军官被解职查办

2019-06-10 05:31

众所周知,美国海军是最先研制和使用电磁弹射器的。但最近,其电磁弹射器的装备行动却被紧急叫停。据美方报道称,新的福特级超级核动力航母2号舰的建造工程受到干预施工中的电磁弹射器安装被紧急叫停,并等待后续命令。

建造中的美军航母预定安装电磁弹射

怎么会有这种情况?很简单,美国军队高层的“蒸汽弹射爱好者”发动了气势汹汹的反击,大有把电磁弹射扔进垃圾桶的架势。当然了,我们知道,从电磁弹射出现开始,伴随着到底是蒸汽弹射好还是电磁弹射器好的争议就一直存在。不过正如已经发生的,美国新一代福特号航母已经带着电磁弹射器服役了,看上去电磁弹射的支持者们取得了最终胜利。但为何又出现这样的反转?

f88786491a3a4f7ba90887845f9d0f69.jpeg


传统的蒸汽弹射

很简单,蒸汽弹射在美军高层有着大量的拥护者,其中铁杆的“蒸汽弹射爱好者”正是美军最高统帅本人。根据俄罗斯方面报道,5月,美统帅十分严厉地指责了一群海军军官,公开声称“电磁弹射器纯属蒙钱,几十亿投资全都打了水漂,必须下马”。其称“电磁弹射疯狂、昂贵、花哨、无用、麻烦缠身”,除了吸引眼球根本比不上蒸汽弹射器。“你们的弹射器创新太多了,而这样的创新在打仗中没有必要”。

88c72eb80ad54d6db38b2da8d63223d6.jpeg


蒸汽弹射器的最大优点是可靠

电磁弹射主要被攻击的地方是其昂贵的造价和较高的故障率。如电磁弹射在装备福特号航母后就没有断过的故障让其“比蒸汽弹射更高的效率、更强的推力和更大的灵活性”变成了空谈,也给快要偃旗息鼓的美军内部的蒸汽弹射支持者们提供了绝妙的弹药——没有什么比实际使用的失误更具备辩驳力和杀伤力的了。而从美军高层的角度而言,造价和维护费用成倍提高的电磁弹射是十分令人头疼的。目前为止,美军为研发和生产电磁弹射器已经起码用掉了30亿美元——约合超过200亿人民币。

福特号的建造引起了争议

如果说一艘福特号无所谓,但美军最终的目标是替换掉现有的尼米兹级航母,造价本就高昂的福特级会因为电磁弹射器的费用而进一步膨胀,无法接受。去年年底就发生过作为蒸汽弹射“爱好者”的美军统帅与航母舰长就弹射方式的辩论,前线指挥官当然从技术革新和作战能力提高的角度,支持了电磁弹射;但从美军高层的角度来看,哪怕忽略掉其故障率,昂贵造价带来的作战能力有限的提高,性价比着实太糟。

e7895148b2084863841a1f296ae77b0f.jpeg


福特号

以美军统帅为代表的美军内部的蒸汽弹射支持者,直接称“之前研究电磁弹射的路全都走错了,搞出了华而不实的东西”,进而呼吁装备改进型的蒸汽弹射器。事件已经不仅仅是技术之争,本月,5名美国海军军官被撤职查办,原因是“在电磁弹射器研究过程中的巨大失误”。很明显,美军统帅打算通过类似的方式强行恢复蒸汽弹射器在未来航母上的地位。而美国海军在这样一个技术问题上导致的内讧持续发酵,或许是美海军矛盾的一次爆发。返回搜狐,查看更多

Electromagnetic bombs are fired! Purely money? 20 billion hits, 5 officers were dismissed and investigated
2019-06-10 05:31

As we all know, the US Navy is the first to develop and use electromagnetic catapults. Recently, however, the equipment action of its electromagnetic catapult was urgently stopped. According to the US report, the construction of the new Ford-class super nuclear-powered aircraft carrier No. 2 was urgently stopped by the installation of the electromagnetic catapult during the intervention and waited for subsequent orders.

The US military aircraft carrier under construction is scheduled to install electromagnetic ejection

How can this happen? Quite simply, the "steam catapults" at the top of the US military launched a powerful counterattack, and they threw electromagnetic bombs into the trash can. Of course, we know that from the beginning of the electromagnetic ejection, the controversy surrounding whether the steam is good or the electromagnetic catapult has always existed. However, as has happened, the new generation of Ford aircraft carrier in the United States has been served with electromagnetic catapults, and it seems that the supporters of electromagnetic ejection have won the final victory. But why is there such a reversal?

Traditional steam ejection

Quite simply, the steam catapult has a large number of supporters at the top of the US military. Among them, the "steam ejecting enthusiast" of the irons is the highest commander of the US military. According to reports from the Russian side, in May, the US commander severely accused a group of naval officers, publicly claiming that "electromagnetic catapults are purely money-saving, and billions of investments have all been squandered and must be dismissed." It is called "electromagnetic bombing crazy, expensive, fancy, useless, troublesome", in addition to attracting the eye can not match the steam catapult. "Your catapult innovation is too much, and such innovation is not necessary in the war."

The biggest advantage of a steam catapult is its reliability.

The main source of electromagnetic ejection is its expensive cost and high failure rate. If the electromagnetic projectile is not equipped with the Ford aircraft carrier, there will be no faults that make it "higher efficiency, stronger thrust and greater flexibility than steam ejection". It becomes empty talk, and it is also given to the internals of the US military that are dying. The steam catapult supporters provided great ammunition – nothing more refutable and lethal than the actual use of the mistake. From the perspective of the top US military, the electromagnetic ejection that doubles the cost and maintenance costs is very troublesome. So far, the US military has spent at least $3 billion on research and development and production of electromagnetic catapults - about 20 billion yuan.

The construction of the Ford caused controversy

If a Ford does not matter, but the ultimate goal of the US military is to replace the existing Nimitz-class aircraft carrier, the costly Ford-class will be further expanded due to the cost of the electromagnetic catapult, unacceptable. At the end of last year, there was a debate about the way the US military commander and the aircraft carrier captain used to be the "fans" of steam ejections. The frontline commanders certainly supported electromagnetic ejection from the perspective of technological innovation and operational capability; but from the perspective of the US military In view of the fact that even if the failure rate is neglected and the combat capability brought by the expensive cost is limited, the price/performance ratio is really bad.

Ford

The steam ejecting supporters inside the US military, represented by the US military commander, directly called "the roads that were previously studied for electromagnetic ejection were all wrong, and they made something slick," and called for a modified steam catapult. The incident is more than just a technical battle. This month, five US Navy officers were dismissed for investigation because of "a huge mistake in the research of electromagnetic catapults." Obviously, the US military commander intends to forcefully restore the position of the steam catapult in the future aircraft carrier in a similar way. The continual fermentation of the guilt caused by the US Navy on such a technical issue may be an outbreak of contradictions between the US and the Navy. Go back to Sohu and see more
