Let me summarize my current thoughts on railguns and how it changes future warship designs.

The most critical issue is the material for the rail, or barrel
  • not only it decides the durability/life of the barrel, it also decides the length of the barrel because with a near-linear acceleration, the end of the barrel wears out first
  • ultimately we shall see multi-barrel, short barrel configuration on large ships, single short barrel configuration on small ships
  • material is China's weakness, so how can they get ahead?
Energy storage and the circuit seem to be easier to solve and develop further
  • The overall energy usage is not a lot. The instantaneous current is huge but only lasts for a very short time.
  • Recharging performance decides rate of fire in burst mode. Potentially this can be done in more than one stages, generator/flywheel/capacitor just like multi-stage cache in a CPU design
  • The super-capacitor etc is challenging but they seem to advance pretty quickly in this area
  • Nuclear generator has its advantages but it is not a pre-requisite
Reading Popular Mechanics' article it says:
  • the railgun requires 25 megawatts of power per shot, enough to power 19,000 homes
  • I guess people are confusing energy with power (energy output per unit time). Laser could be called a high-energy weapon. Railguns are not.

Do you know the definition of among? which is "in the midst of" yet he quoted Dafengcao that mean Dafencao is the first and he followed by quoting it . So be careful when you want to dispute it
Anyway talking about the devil here he is having trouble reconciling the superiority of US EMRG technology and the appearance of Rail gun on Haiyang shan So the way out denial of course here it is. The question why would anyone put it on ship if it does not work?
Assuming this is China’s first railgun, it could be argued that mounting it on a ship steals a march on the U.S. Navy. Then again, we know the U.S. Navy's weapon works and has worked for years. China's is probably not an operational weapon system,

Is China Getting Ready To Test a Railgun?

Parked on the Yangtze river is something that sure looks like a railgun, and a sign that China might have beaten the U.S. Navy in putting this weapon on a ship.

China appears to be the first country to place a electromagnetic railgun on a ship. The weapon was spotted on an old Chinese Navy landing craft in Wuhan and images of it quickly spread across the Internet. If this is true, then China has placed a real railgun on a warship before the U.S. Navy, which has been testing its own railgun on land for years.

Electromagnetic railguns are an entirely new type of weapon system that use electricity and magnetism instead of the energy of a gunpowder explosion. Railguns use electricity to generate very strong electromagnetic fields between two rails. A conductive metal device, called an armature, picks up a projectile and accelerates down the path between the rails, slinging the projectile downrange.

Images of the

Haiyangshan with a large gun turret-like object appeared on social media yesterday morning. The ship, which is a 390-foot tank-landing ship designed to carry up to 10 tanks or 500 tons of cargo, has a wide cargo deck area that is currently is crowded with shipping containers and equipment. Mounted on the bow of Haiyangshan is what clearly looks like a gun turret with a large, stepped barrel.

Large guns mounted on ships would be useful for bombardment missions (*cough*Taiwan *cough*), but China has stuck with 130-millimeter guns for its Navy and appears disinterested in large guns, which is one reason to doubt this is a conventional weapon. Also, this gun is huge but has a stubby barrel, which would limit its range if it were a conventional weapon. Furthermore if, this was an ordinary chemically powered gun, there would be no need for the additional equipment scattered about on the deck of the landing craft.

Conclusion: What we are looking at is an electromagnetic railgun, the same kind that

, and has since 2012. Here’s the Navy’s railgun slinging multiple hypervelocity rounds in 2017:

Railguns are extremely complex instruments that require immense amounts of power. BAE Systems and the U.S. Navy have been working on railgun technology at the Naval Surface Warfare Center, Dahlgren Division, and fired their first shots in 2010.

The land-based American system can accelerate a 23 pound metal projectile to 4,500 miles an hour, and the Navy’s goal is an effective range of more than 100 miles. To achieve this feat, the railgun requires 25 megawatts of power per shot, enough to power 19,000 homes.

The "Yangtze River Monster" under way.

China’s railgun weapon and the Haiyangshan are currently parked on the Yangtze at the Wuchang Shipyards in Wuhan, China. Although this location lies more than a hundred miles inland, the Yangtze is navigable by seagoing vessels for up to a thousand miles. Far from the heavily watched shipyards on the coastline, Wuchang is a good place to quietly conduct shipboard trials of a new weapon system on an actual ship. That is, until the trials attract attention from curious ship spotters with access to social media.

Railguns have the potential to revolutionize warfare. Faster than missiles and longer ranged than conventional guns, railguns could shoot enemy airplanes, anti-ship missiles, and ballistic missiles out of the sky, skewer enemy warships, and bombard targets on land. One weapon could fulfill many roles.

China thought to have been working on a railgun system for years but nobody outside of the intelligence community knew the extent of progress Beijing has made. Even with these photos we still know very little: Is this the first railgun, or the tenth? How much power does it require? Has it been fired before?

Assuming this is China’s first railgun, it could be argued that mounting it on a ship steals a march on the U.S. Navy. Then again, we know the U.S. Navy's weapon works and has worked for years. China's is probably not an operational weapon system, so for now it doesn’t really matter if it’s on a ship or not. We don’t know if China is ahead of America in the railgun game, but one thing is for sure: America’s lead in railgun tech is not as far forward as everyone thought it was.

I guess we should just wait for more information. We really don't know anything about the Chinese project at this time. I am sure more will begin to become available if they are testing this project where it is easily visible in the open.

This isn't a very interesting capability, to be frank. Railguns are mostly useful for shore bombardment; when tasked against other ships, they lack the range and rate of fire to be truly lethal. China is a country that has difficulty obtaining sea supremacy; the total VLS capacity of the US navy comes out to more than 7000 silos so if the USN were concentrated on the East China Sea, the Chinese would be in deep trouble.

That said, the related EM-assisted VLS technology the Chinese sport is very interesting.

Actually we know a lot Chinese has been prolific writer of technical paper about railgun and over the year we have news about the progress of rail gun. Except we don't pay attention to it

TYPE 055A

The Type 055A, shown here in this fan art, will have integrated electric propulsion, giving it enough electricity to carry energy-intensive railguns.

Nishikasaizoukan

China has been making under-the-radar advances in railguns and other electromagnetic technologies, a move that's particularly notable considering the U.S. Navy has just recently reduced its efforts developing this kind of technology.
As opposed to gunpowder, railguns use electromagnetic energy to sling out a projectile, which means there's potential for far greater speed and range—the equivalent of a cannon with missile effects. Essentially, a railgun is an electromagnetic-powered cannon that's fires hypersonic shells by applying parallel magnetic fields (or "rails") on the shells

While the technology has received great attention in United States military circles, China is the nation producing the most unclassified, peer-reviewed electromagnetic launch research in the world. It's the type of public science that suggests China could field a range of military electromagnetic technologies in the future.

CHINESE RAILGUN

This early Chinese railgun or coilgun (pre-2005) is part of Chinese electromagnetic research, which began in the 1980s. While railguns are relatively simple to build, the difficulty lies in scaling them up, as well as making the barrel durable enough for multiple firings.

Chinese Internet, via Strategy Center

What's more, in a presentation at the PLAN University in Wuhan (home to the land-based testing rigs for the Chinese aircraft carrier and the Type 055 destroyer) Rear Admiral Ma Weiming told Chinese experts in electromagnetic research that the country has made breakthroughs in key areas of electromagnetic applications, such as railguns and electromagnetic-assisted launch system (EMALS) catapults.

Admiral Ma noted that some of the breakthroughs were key to building an operational railgun. That could mean these innovations involve decreasing gun barrel wear, power storage and management, and/or energy efficiency.

It's an upgrade over the traditional gun, not a replacement of the VLS. If the USN brought all 7000 VLS and its ships into the ECS, it'd be facing the ASBMs of the Chinese mainland, not a VLS to VLS battle with the PLAN. And a situation where the US threatens China with its full naval force would have great potential to immediately depart the realm of ship warfare and enter nuclear Armageddon.

We're just talking about improving weapons systems here and happy that China is doing that with its rail-gun tests. We're not escalating the discussion to WWIII quite yet LOL

Actually EMRG is the perfect CIWS to guard against those missile It is fast , efficient, plenty of munition whereas missile like HJ 10, or HHQ9 is limited in number and can be ovewhelm by opponent
