中國第四艘航母使用核能為動力 -- Allegra Mendelson
China building supercarrier to rival US
China building supercarrier to rival US
Nuclear-powered warship will match capability of USS Gerald R Ford
Allegra Mendelson, 03/03/25
China is developing a new nuclear-powered aircraft carrier which would be larger and more advanced than any existing vessel in its fleet, in an attempt to keep pace with the US navy.
The new supercarrier would allow fighter jets to be launched from four parts of the flight deck, as opposed to its current ships which can only facilitate three, according to new satellite imagery reviewed by NBC News.
That would match the capability of USS Gerald R. Ford, the largest and most advanced aircraft carrier in the US navy.
Images from the Dalian shipbuilding facility in north-east China show tracks or trenches in the snow, which appear to be related to a new catapult launch system.

Analysts said that while the images don’t show construction under way just yet, they are an indication that China is moving forward with its ambitious plans.
“We think this is them testing equipment and layouts for the upcoming Type 04 carrier,” Michael Duitsman, a researcher at the James Martin Center for Nonproliferation Studies in the US, told NBC.
China’s first aircraft carrier, the Liaoning, was commissioned in 2012 and its second, the Shandong, was launched in 2017. Both use the “ski-jump” method, which involves a ramp at the end of a short runway to propel the planes upward.

The country’s third and most advanced carrier to date, the Fujian, launched in 2022 and was upgraded with electromagnetic catapults, which are more similar to the systems used onboard US ships.
All three of China’s carriers are conventionally powered, unlike the upcoming one, which experts believe would be powered by a nuclear reactor given its size and capacity.
The tracks seen in the latest satellite images run at convergent angles, which experts say resemble the configuration of existing American supercarriers that have four electromagnetic catapults.
Mr Duitsman said that it seems likely that China’s new carrier would resemble the USS Gerald R. Ford.

China already has the largest navy in the world, with 370 military vessels, but America, with 291 vessels, has more big ships.
The Gerald Ford is one of 11 supercarriers in the US navy.
Rumours have circulated for years that China is preparing to build a Type 04 carrier. However, Beijing has refused to confirm any reports and very little information has been made public.

Last November, analysts at the Middlebury Institute of International Studies in the US revealed that China had built a land-based prototype nuclear reactor for a large surface warship.
Until the satellite images from Dalian, this was the first and only piece of evidence that Beijing was developing a nuclear-powered aircraft carrier.
China has not commented on the latest reports about its plans for a supercarrier. However, last March, Yuan Huazhi, the political commissar of the Chinese People’s Liberation Army navy, told the state-backed Global Times that there was no bottleneck in China’s aircraft carrier technologies and development was progressing smoothly.
At the time, Yuan also said that more information would be made available “soon”, but little has been heard from Beijing since.

中、美爭霸誰能掌控制空權？ - Chris Panella

可視為爭取海軍軍費的「說貼」。
China could stop US airpower from achieving air superiority in the first island chain, top commander says
Chris Panella, 04/19/25
* China's air force is capable of denying US superiority in the first island chain, the top US commander in the Pacific said.
* Adm. Samuel Paparo said that China's fighter fleet, bombers, and missiles are enough to cause problems.
* He said that neither side would see air supremacy in a potential war.
China can prevent the US from achieving air superiority within the key first island chain, America's top commander in the Indo-Pacific region said.
Last week, Adm. Samuel Paparo, the head of US Indo-Pacific Command, gave China "high marks" in its ability to prevent the US from achieving air superiority in the first island chain, the strategic archipelagos in East Asia that includes Japan, Taiwan, and the northern Philippines, among other territories.
In a hearing with the US Senate Armed Services Committee, Paparo pointed to China's air force. He said that China now has 2,100 fighters and 200 H-6 bombers and a production rate for fighters that's currently 1.2 to 1 over the US.
China still operates a lot of older airframes, but the number of capable fourth-generation platforms is on the rise, as is its number of fifth-gen fighters. And the country continues to work on new aircraft designs.
"Furthermore," Paparo explained during the hearing, "their advanced long-range air-to-air missiles also present a tremendous threat." China has prioritized building up its missile stockpiles and capabilities in recent years, particularly ones capable of targeting US and allied forces and installations, including insufficiently defended airfields, in the region.
Air superiority, like the US military has enjoyed in conflicts in the Middle East in recent decades, requires securing a substantial degree of control over the skies with little interference from the enemy, meaning aircraft can operate with flexibility and provide support for other forces.
Ceding that air superiority, Paparo said, "is not an option if we intend to maintain capability against our adversaries and the ability to support our allies," especially in the first island chain.
But both the US and Chinese air forces have been rethinking what air superiority would look like in a conflict and questioning whether that is even possible for more than brief windows of time.
With both sides employing advanced sensors and long-range weapons, including formidable air defenses, permanently controlling the skies seems increasingly unlikely.
That said, the admiral explained that he has "some game," too. In a conflict, neither Beijing nor Washington's forces would likely achieve air supremacy, or complete control, Paparo said.
"It will be my job to contest air superiority, to protect those forces that are on the first island chain, such as 3rd Marine Expeditionary Force," the commander explained to lawmakers, "and also to provide windows of air superiority in order to achieve our effects."
Officials and experts have often discussed what the future US Air Force strategy against China should look like, the role of unmanned aerial systems in that, and how air power could determine the outcome of a war.
Also important is considering how China's air defense systems would protect important targets, such as critical command and control centers, air bases, and radar sites.
Researchers have said that China could more easily devastate American airpower than the other way around.
Some have pointed to the importance of hardening US airbases and bolstering air defenses in the Indo-Pacific to improve the survivability of American aircraft should China launch a missile strike. Lawmakers in Washington have said the US isn't doing enough in that regard.
