China's Megaton EMP warheads

1. A thermonuclear warhead (see project Starfish Prime) is itself an EMP warhead. China's DF-5 ICBM is armed with a five megaton thermonuclear warhead. Hence, the lower limit of Chinese EMP weapon capability is five megatons.

2. On the EMP chart, you can see that China's five megaton EMP warhead has a radius of 1,500 miles (see chart below).

3. 25 years ago, China detonated an enhanced radiation weapon or a neutron bomb. If China possesses the skill to tune a thermonuclear warhead to produce excessive neutrons then it's reasonable to believe China can tune thermonuclear warheads to produce excessive gamma rays for an EMP warhead.

4. The citations from MissileThreat.com/Jane's Defense show that China has built EMP warheads for its DF-21A and DF-25 MRBMs and JL-1A SLBM. Hence, China can easily install the same EMP warheads on ICBMs or the longer-range JL-2 SLBM.

5. I don't really care whether you want to use a five megaton or 16.5 megaton EMP warhead for Chinese capabilities. There isn't that much of a difference. The effective radius is somewhere between 1,500 to 2,000 miles.

using EMP is flawed tactics,as it destroys a large area.it generally do more harm than good.and also,US military is using EMP resistant electronic parts many years now(since Cold War).EMP isn't an effective weapon against US Armed force(and many other Armed forces also),but against civilians where these infrastructures are non-existent.

You're wrong. Physics is physics. A jet fighter will drop out of the sky when a megaton EMP warhead detonates. All of the electronics and electrical wiring within the aircraft will fuse.

You need many feet of lead to stop 50,000 volts per meter from damaging electronics and electrical wiring. Have you seen an airborne fighter with many feet of lead on all sides to prevent damage from an EMP blast? I didn't think so.

Classified Super-EMP nuclear warhead can overcome 50,000 volts per meter limit

Does China have Super-EMP nuclear warhead technology to wreak damage in excess of 50,000 volts per meter?

There are press reports to indicate this is the case, but no one at the Pentagon or the CIA has been willing to go on the record to confirm it.

As usual, the Pentagon's annual report on the Chinese military is useless. They don't bother discussing China's most potent weapons or only briefly touch upon it.

Electromagnetic pulse - Wikipedia, the free encyclopedia

"These 2 MeV gamma rays will normally produce an E1 pulse near ground level at moderately high latitudes that peaks at about 50,000 volts per metre. This is a peak power density of 6.6 megawatts per square metre.

The process of the gamma rays knocking electrons out of the atoms in the mid-stratosphere causes this region of the atmosphere to become an electrical conductor due to ionization, a process which blocks the production of further electromagnetic signals and causes the field strength to saturate at about 50,000 volts per metre. The strength of the E1 pulse depends upon the number and intensity of the gamma rays produced by the weapon and upon the rapidity of the gamma ray burst from the weapon. The strength of the E1 pulse is also somewhat dependent upon the altitude of the detonation.

There are reports of "super-EMP" nuclear weapons that are able to overcome the 50,000 volt per metre limit by the very nearly instantaneous release of a burst of gamma radiation of much higher energy levels than are known to be produced by second-generation nuclear weapons. The reality and possible construction details of these weapons are classified, and therefore cannot be confirmed by scientists in the open scientific literature.[19]"

Footnote 19: "Statement, Dr. Peter Vincent Pry, EMP Commission Staff, before the United States Senate Subcommittee on Terrorism, Technology and Homeland Security. March 8, 2005 [11]" http://kyl.senate.gov/legis_center/subdocs/030805_pry.pdf

 

[Skull and Bones]

Here's a data on the percent of Gamma ray emission from a typical high altitude nuclear detonation.

How the peak EMP on the ground varies with the weapon yield and burst altitude. Note that the yield here is the prompt gamma ray output measured in kilotons. This varies from 0.1-0.5% of the total weapon yield, depending on weapon design. The 1.4 Mt total yield 1962 Starfish test had an output of 0.1%, hence 1.4 kt of prompt gamma rays. (The blue 'pre-ionisation' curve applies where gamma and x-rays from the weapon's primary stage ionise the atmosphere, making it electrically conductive before the main pulse from the thermonuclear stage. The pre-ionisation can literally short out part of the final EMP.)

Even taking the highest value of 0.5% and and increasing the yield by a factor of 2 in Enhanced Radiation mode, the percent of Gamma Ray yield will barely increase by 1%.

Future Weapons did an EMP test to see the affects it would have on an RC helicopter. As soon as the RC helo reached an altitude where the EMP field was present it shut down and came hurling downwards back to ground. They also test driving a vehicle through the EMP field, vehicle's electronics become disabled and the car comes to a halt.

It doesn't need to cover lead all around to defend electronic parts from EMP..read this..

The E-4B offered a vast increase in communications capability over the previous model and was considered to be 'hardened' against the effects of electromagnetic pulse (EMP) from a nuclear blast. Hardening the aircraft meant that all equipment and wiring on board was shielded from EMP.

by the way,when China is taking similar path of Russia in this sector,USA is already far ahead and built this..

Post–Cold War nuclear EMP attack scenarios

The United States military services have developed, and in some cases have published, a number of hypothetical EMP attack scenarios.[42]
The United States EMP Commission was authorized by the United States Congress in Fiscal Year 2001, and re-authorized in Fiscal Year 2006. The commission is formally known as the Commission to Assess the Threat to the United States from Electromagnetic Pulse (EMP) Attack.[43]
The United States EMP Commission has brought together a group of notable scientists and technologists to compile several reports. In 2008, the EMP Commission released the Critical National Infrastructures Report.[34] This report describes, in as much detail as practical, the likely consequences of a nuclear EMP on civilian infrastructures. Although this report was directed specifically toward the United States, most of the information can obviously be generalized to the civilian infrastructure of other industrialized countries.
The 2008 report was a followup to a more generalized report issued by the commission in 2004.[22][44]
In written testimony delivered to the United States Senate in 2005, an EMP Commission staff member reported:
The EMP Commission sponsored a worldwide survey of foreign scientific and military literature to evaluate the knowledge, and possibly the intentions, of foreign states with respect to electromagnetic pulse (EMP) attack. The survey found that the physics of EMP phenomenon and the military potential of EMP attack are widely understood in the international community, as reflected in official and unofficial writings and statements. The survey of open sources over the past decade finds that knowledge about EMP and EMP attack is evidenced in at least Britain, France, Germany, Israel, Egypt, Taiwan, Sweden, Cuba, India, Pakistan, Iraq under Saddam Hussein, Iran, North Korea, China and Russia.
. . .
Many foreign analysts–particularly in Iran, North Korea, China, and Russia–view the United States as a potential aggressor that would be willing to use its entire panoply of weapons, including nuclear weapons, in a first strike. They perceive the United States as having contingency plans to make a nuclear EMP attack, and as being willing to execute those plans under a broad range of circumstances.
Russian and Chinese military scientists in open source writings describe the basic principles of nuclear weapons designed specifically to generate an enhanced-EMP effect, that they term "Super-EMP" weapons. "Super-EMP" weapons, according to these foreign open source writings, can destroy even the best protected U.S. military and civilian electronic systems

Hardening refers to conventional EMP warheads of low voltage.

We're talking at least five megatons causing 50,000 volts per meter.

See the difference?

Shielding will be equally effective in this case also, and 50000 volts/meter is the peak voltage above the detonation points, it'll reduce drastically with distance.

A 5 megaton nuke cannot give a yield of 16.5 megaton.


Probably can't exist
ASBM's are unproven concept and face practical difficulties.



does not exist



Does not exist



Does not exist



Does not exist.

There are some nuclear armed depth charges but no thermonuclear torpedo.Thermonuclear weapons have never been miniaturized enough.




Does not exist.

They， and more， all exist one way or another。

You know practically nothing about what China has up her sleeves。

But it is your born-right not to believe such。

Very informative posts by Martian2.

Look at these Indians rattled like a fish out of water . Their dream of thinking they were close to China has been thoroughly shattered, they are in full denial mode . China has weapons systems Indians don't even know that such weapons exists. The weapons Martian2 listed, India don't even know what they are, let alone making their own .
Indians definitely received a brutal shock how far lagging India truly is.

Keep them coming Martian2, I want to see more Indians in full denial mode.

I understand, but EMP generation is directly proportional to Gamma ray emission. Now what is the percentage increase of Gamma ray emission in an Enhanced Radiation warhead?

Without any proof of that, it's futile to make such absurd claims. Probabilities are, the gamma ray emission are far lower in Enhanced radiation warhead than typical nuclear warhead.



I understand Sir, but his claims defies physics. So just playing around him a bit.

A point of confusion amongst many people (including me, I admit) is that gamma rays sees to be proportional to the yield. That is not always the case. Nuclear weapons can be made to specifically release huge amounts of radiation while maintaining a low blast radius or vice versa, allowing limited structural damage but massive casualties.

][/FONT]There are practical difficulties targeting a moving vessel in open ocean.Testing a ballistic missile against a stationary target proves nothing.

China has all the technology to make it happen. MaRVs, OTH radar, surveillance aircraft and UAV, etc. The fact that it has been tested means that such maneuvers were tested as well.

][/FONT]In prototype stage only.

No country has a functional spaceplane.

Isn't that the question being begged?

][/FONT]Classical fanboyism.

Everyone is developing a Stealth cruise missile.No one has succeeded.

AGM-129. If an aircraft can have VLO, a smaller missile certainly can.

][/FONT]I have already pointed toward existence of Nuclear depth charges.

The problem with thermonuclear torpedo is that warhead cannot be miniaturized to required size.

Also you do not need a nuclear explosion to occur under the hull to destroy a ship.

Thermonuclear devices can be miniaturized; the question here is safety and practicality.

][/FONT]LOL

Claim to exclusive information.

Simple does not exist because Speed and maneuverability has inverse relation.And a test of hypersonic cruise missile cannot be missed.

False. Maneuverability depends on thrust to weight ratio and aerodynamics. PLA military insiders and officials have already confirmed the missile. It was successfully tested.

][/FONT]Some of your compatriots has their head planted so deep in their As$ that they could not seprate fantasy from reality.

I just showed you evidence of all the accounts. You have shown none against them.

I have already proved my point about the yield of enhanced Radiation warhead is mostly X-ray and neutron emissions, which doesn't generate flux for electromagnetic pulse. And enhanced radiation warhead is by no means a EMP device.

If you want to debate, then debate in the language of physics and technicalities, not by the mental masturbation of @Martian2.

False. Maneuverability depends on thrust to weight ratio and aerodynamics. PLA military insiders and officials have already confirmed the missile. It was successfully tested.

What a noob.

Maneuverability depends only on the aerodynamic lift (which in turn depends on wing loading) and nothing else, thrust to weight ratio is an indicator only for acceleration.

Debate at The Economist on EMP

I'm having a lively debate in the comment section of The Economist on a Chinese 16.5 megaton EMP detonation over Japan. I've reproduced it here in case anyone wants to read it.

Comments on North Korea

Comment section:

Martin Su Feb 15th, 19:48

If China detonates a 16.5 megaton EMP (electromagnetic pulse) warhead over Japan, there will be a lot of sitting ducks.

Normally, China's DF-5 ICBM carries a five megaton thermonuclear warhead. According to the Federation of American Scientists, an enhanced radiation weapon (such as an EMP warhead) has a multiplicative factor of 3.3 when a normal nuclear warhead is specifically tuned to emit gamma rays.

----------

Michael Dunne in reply to Martin Su Feb 16th, 23:52

And what would be the point of detonating a 16.5 megaton warhead above Japan?

Probably not a great avenue to take, considering proximity to China, that Japan is under the US nuclear umbrella, etc.

----------

Martin Su in reply to Michael Dunne 25 mins ago

Detonating a 16.5 megaton EMP above Japan will neutralize all aircraft and surface warships in Japan.

An EMP covers an area with a radius of 1,500 miles and creates 50,000 volts per meter through the Compton effect in electrical wiring and electronics.

No one will be killed and the Japanese will be unable to fight a war. In essence, Japan can only surrender.

AtlantisKing in reply to Martin Su 13 mins ago

And why would China do something so foolish? Japan is under the US nuclera umbrella. A nuclear attack against it is tantamount to a war declaration. Why would China do that? To protect North Korea? Nahhh

Incidentally, there are a number of military assets that are hardened against EMPs (and China knows that)

----------

Martin Su in reply to AtlantisKing 7 mins ago

An EMP is not a nuclear attack. In a nuclear attack, millions of people die. In contrast, an EMP is exploded 100 miles above Japan and hurts no one.

Though an EMP is powered by a thermonuclear weapon, it merely emits massive electromagnetic waves. The EMP destroys weapon systems, but does not harm people.

It is true that China has 41 super-hardened airbases located under mountains or hills of granite. However, the Japanese and foreign airbases (such as Kadena) are all above-ground and unprotected against a massive EMP.
