Re: PLAN Carrier Operations..News, Videos & Photos

Think about the kinetic energy of something coming in at Mach 10. Think about what the guidance of something like an ASBM would be coming in at that speed? Think about what is used in an ASBM system to detect and track targets. Do you really think having radar deflector helps? Think about the accuracy of a ballistic missile coming in at Mach 10. Is it more important to have a large area where it can land or a smaller ship?

These are very basic questions to think about which makes this entire YuanWang 4 theory sound very implausible. btw, amongst what I would called legitimate sources on Chinese bbs, I have not seen anything on this. And I follow Chinese military bbs very closely.

Lol let's not exaggerate :p
We've all said how DF-21D probably can't, and wasn't designed, to sink a supercarrier (at least not with one shot) and there's no reason the former yuanwang ship could've been tested against a dummy warhead
No exageration. I would presume a dummy warhed. They would be seeing if they could "hit" it. but that vessel, if it were hit by an incoming ballistic missile RV the size of the DF-21D warhead would have massive damage just from the kinetic energy alone. There would be massive damage somewhere on the top of the ship (given the angle of reentry) if it were hit.

My guess is that the vessel was not involved at all in the test of a DF-21D. It sank, for whatever reason, in shallow waters according to report, while in tow. I do not believe that would be the profile for such a test.

In addition, other nations, the US inparticular would have detected such a test and, if there had been no advanced warning, would have protested it.

The US this week actually did test a hypersonic strike wepaon that flew to and hit its target on an atoll in the Pacific, flying 2300 miles in less than 30 minutes at over Mach 5. It was well announced and open about it. I expect when the PRC tests the DF-21D in a live test into the Ocean, and probably well out to Sea somewhere, they will let others know and establish some kind of zone around the target area.

You still didn't answer my question. All that you have stated must applied as well to ICBM. Using your reasoning there will be no ICBM! .

Tracking is no problem US has NOSS China has Yaogan 9. Right now China has 24 dedicated military Surveillance and ICR satellite and about 70 dual use satellites
CBG is not exactly quiet you have plane taking off and landing all the time You got all kind electromagnetic signature coming off from CBG

Add to that 3 OVH radar , surveillance plant and spy ship you have an integrated C4ISR

Again, it could easily have been a "graze" -- which at the speeds the dummy warhead could have been travelling at could easily have caused the ship to sink.

Yes I've made this point as well.

That's different... AShBM is meant to hit something the size of a football field. ICBM is meant to hit anywhere in the vicinity of a city.

Besides what was your question in the first place? Why yuanwang 4 was fitted with such massive radar reflectors? Weapons testing is the answer but DF-21D probably wasn't the weapon.

The ship don't even have to be sinked. The ship, installed with the reflectors, could be used to simulate the RCS signature of a carrier. The functionality of the AShBM seeker can be tested by mounting it on a test aircraft and flying it high over the simulated targed.

I agree with the first two sentences. But a big question of how effective the seeker will be is when it's travelling down at mach 10 and seeing whether it still works then, mounting it on an aircraft won't do much good.

Are you sure about this !
Now how can you explain it to me this photo. China has the most active ballistic missile test in the world now according to ONI

I wish you could actually tell me what part of my post that I'm sure about.

I'm saying there's nothing definitive to suggest yuanwang 4 was involved in an AShBM test, I'm not disputing china's ballistic missile development or the idea that that phot could be result of a previous AShBM test against a land target.

firng DF-21 could easily detected by NORAD,judgihg from the damage more likely C-802

C-802 doesn't need corner reflectors for such a large target. Most importantly, corner reflectors pointing skyward would be useless for C-802.

Think about the kinetic energy of something coming in at Mach 10.
The amount of kinetic energy that matters would be the energy that get imparted onto the ship. If a warhead goes through the structure like a bullet through paper, then little energy would get transfered on to the ship. The warhead would punch a big hole through the hull at the end of the day, but much of it will just go to the bottom of the ocean.

Think about what the guidance of something like an ASBM would be coming in at that speed? Think about what is used in an ASBM system to detect and track targets. Do you really think having radar deflector helps? Think about the accuracy of a ballistic missile coming in at Mach 10. Is it more important to have a large area where it can land or a smaller ship?

At the same time, think about why they need corner reflectors, in particular reflectors that point upward. Why would they install them if they don't help tracking in any way? If they were only testing sensors, they could have used any ship; why must they specifically select a decommissioned ship? If there really was a weapon test, why did they want to use a big ship instead of using a small barge with corner reflectors pointing upward?

The idea is to test the sensitivity of the seeker to the simulated carrier RCS from various distances, from as far away as possibly can, down to the nearer distances. The blackout during the reentry of the missile and its high speed maneouvre would have to be separately simulated either through software or by an actual final testing.
