China Ballistic Missiles and Nuclear Arms Thread

Exactly let do the calc to get the feel By the time the warhead enter the atmosphere it roughly 100km=62miles. Now mach 10 warhead speeding at 7672miles/hr
So the Carrier has only (62/7672) X60 minutes=0.48 minute to travel. Now how fast is the ship say 30 knots=34.5 miles /hour=50 ft/second X 0.48 X 60=1440 feet=0.27 mile Now calculate the area piXRsquare= 3.14 X 0.27 X0.27=0.228 square miles of kill zone. Calculate the angle = power-1( tan(0.27/62))=0.24 degree deviation from 90 degree straight down. So the warhead only has to make 0.24 degree adjustment once the sensor detect the ship

I think that the biggest value of that radar is its intelligence gathering capability during peacetime. Something much more useful to the Americans than the Taiwanese. But that’s how it is when you are vassalized.

Even if they are capable to jam it, it would be folly to advertise it. In that event, the other side could assume an attack is imminent and take irrevocable action leading to a major escalation.

You never bother to read what I wrote?
Your reading limited to 2013 article in WIRED?

China did that and done that in 2014.
Murica pretended it did not happened even though they stewed and stewed at that slap at their face.

The world never seen any major escalation in 2014 , as if nothing happened.
Just like the successful test on Yuan Wang 4 in 2010 that pop the eyes of Muricans when they seen via satellite Yuan Wang 4 being hit .
And Murican pretended it did not happened.

Murica good at pretending.

Such as pretending Covid19 came from Wuhan when more likely than not, that came from Murica.

Antiship ballistic missile has to be multiwarheaded. Before warheads descend atmosphere, a final update on carrier current position from satellite and calculation of projected possible position of carriers . It may go forward, turn left , right . The multiple warheads would be projected at those possible spots. More warheads means it cover more possible positions. After final calculations, warheads will be projected ahead accordingly in a very short span of time.

If each missile carry 10 warheads and two missiles will have 20 warheads and cover 20 different spots. It's very likely one or more warhead will be projected correctly and match the carriers new position.

Anything come down and hitting at Mach 10 be very very very bad news and do not even need any explosives with them.
APFSD at Mach 4 ++ weigh only about 4 kg in business end. And thats enough to kill all in a tank weighing over 60 tons.

Anything Mach10 will be a lot lot more devastating than APFSD.

40 kg or less be enough to give the good news to those that received it.



There is a strong possibility that those are MARVED. To maximise the chances of your brave sailors you send against China in Carriers on phony FONOPs will remain forever young.

Do take a look at this video of DF26. On top of those 300++ numbers of DFs, DF26 appeared to be MARVED as well.

And for all you guess, DF21Ds might well be MARVED as well. But might be figment of fertile imagination of creator of that video.
Your guess as good as mine.

You feeling lucky enough?

And even if not MARVED, there are still 300++ of them. You hope, or think, everyone of them will miss?

So please be peaceful and respectful and more courtesy, and no more phony FONOPs and playing games of who will blink with China with phony FONOPs.
Do not play with fire regarding Taiwan.

I will not even talk of the 3000++ Mach 3s YJ12s YJ18s , and the recently revealed Mach 10 DF100s as these are not ballistic missiles and other threads exist for them.

If someone says God doesn't exists, it's up to believers to prove God exists and up until then God doesn't exist.

Not exactly.
Be the very definition of belief, anyone can believe anything. They are free to do so without burden of proof. It works in both ways.
As long as they are not crossing paths, there is no burden of proof.

And the "proof" of "existence of god" (yes/no) is an impossibility.

it's amazing to read the posts by the "just hatched" genius like this. don't want to be rude, did you finish your high school? ever heard the thing called inertia? carriers are massive with huge inertia, they cannot change course in short order.

You mixed up the times. If the warhead detect the ship at 100 km height then the target position error at that point and the correction requirement needs to be the time from launch until the 100 km height detection point, NOT the flight time from 100 km to the target.

Wrong the missile get the latest update as to carrier position before it enter the atmosphere then when the warhead enter atmosphere where it engulf in plasma. So the warhead deviation is from 100 km to target and that is very small. The farthest the carrier can go is 0.27miles! radius.

But somebody said just before the warhead enter atmosphere it release it own sensor to guide the warhead as it get out of the plasma. Not sure how it work

It is not realistic to assume perfect target tracking information and perfect navigation throughout the ballistic missile trajectory. @Anslvrthng is right on this.

The antiship Tomahawk was designed so that it can perform multiple passes for search and detection, before homing on a target. Its operational range was just half the straight line range of 500nm. It was considered largely a failure based on simulated exercises due to inability to cue and guide the missiles to target at such ranges: it often failed to hit the target and when it did, it often hit the wrong target.

During the Cold War, the Russians used HF/DF systems (think of Krug antenna) as part of their SOSS. This was complemented by submarine and surface pickets and later with ELINT aircraft and satellites. The initial Krug data was used to vector in surveillance aircraft (think of Bear D) and to cue radar ocean surveillance satellites. The US Sixth Fleet had a saying: “Bears in the morning, missiles in the afternoon”.

Such long distance targeting is still susceptible to deception: US destroyers all employed blip enhancers, making them appear on radar as aircraft carriers. The Soviets therefore practiced getting real close, so that they can positively identify the carrier within the formation.

In case of a 10 warhead MIRV, how big can each warhead be? What is the throw weight of DF-16 and DF-21? According to Wiki they would have to be under 60kg each for DF-21.

As I said the missile/warhead release a small satellite sensor before it enter the atmosphere update the latest carrier position and direction of the ship . While the warhead enter atmosphere , engulf in plasma, out of plasma then update again before it hit the target. Those aircraft carrier is a huge beast they can't change direction in a dime or half a minute. so knowing the direction(angle) the warhead can make adjustment
Why it is not possible? Tell me?

It work because they tested it in front of world and sofar nobody said anything. If it failed I am sure they will leak the news and the western press will jump up and down mocking the attempt
