China Tests Midcourse Missile Interception

[badguy2000]

most defense blogs say any country which has an IRBM and a hit to kill interceptor and a decent radar can do the same.

however, in fact, only USA and CHina have finished such tests. haha.

BTW, "to do" is cheap but "done" is expensive.
"talks" are cheap while "practice" are always hard.

India's BMD program...

India has not prove its capacity of shooting anything in exosphere yet!~

so far you have posted nothing but hype and fanboy praise; India has conducted exosphere testing BEFORE China.

Indian BMD test success, third time in a row

Defence Research and Development Organisation (DRDO) has flight tested a Ballistic Missile Interceptor for the third time on 06 March 2009 at 1624 hrs from Wheeler Island, Integrated Test Range (ITR) successfully achieving the mission objectives set. The two stage Interceptor Missile fitted with advanced systems has neutralized the target, enemy missile at 75 Kms altitude. Click For Pictures
To mimic the incoming enemy’s ballistic missile trajectory Dhanush missile went to an altitude of 120 Km and was launched from ship about 100 km away from Coast. The Interceptor missile was launched using mobile launcher located on Wheeler Island Launch Complex.

This is the second test flight of the Exo atmospheric Kill Vehicle called PAD. This was a direct hit.
The third consecutive interception of Ballistic Missiles once again demonstrated the robustness of the Indian BMD system. DRDO in past has conducted two interception trials, first in Exo-atmospheric region at 48 Kms altitude on 27th November 06 and second in endo-atmospheric region at 15 kms using AAD missile on 06 Dec 07.

I have given you links with all the countires that have done mid course interception, if it bursts your bubble and you don't want to accept it that is up to you. Most nations don' need to show off to the world that they are something like China does.

75KM,ah? tell me the definition of "axosphere" in India first ,ok?
otherwise it will become a talk between a duck and a cock!

 

[LETHALFORCE]

This was a test of the kill vehicle when the range needs to increased it will be placed with a missile to satify that. The Kill vehicle is really what separates the countries that have this ability from the ones that don't and the countries late in the game like China the 8th country to do this.

at what hight china made the interception ??? with link please.

the interceptor will be modified Agni 1 single stage missile, with the kill vehicle.:twizt:

I am not positive but i remember reading the Chinese test was done at 47km
in one of the American news sources.

 

[sayareakd]

not much of information is coming from the PRC about the chines missile interceptor, therefore much space is left for speculation.......... it will be better if video of the test is release by PRC govt.

 

[badguy2000]

guy, here is a degestion from a academic journal. it is helpful for you understand somthing about the interception for ICBM.
however, it is in CHinese, so I have to translate it into english.

BTW,according to the journal ,at the hight of 75 KMs,ICBM has already entered into terminal phase.

booste phase is finished at the hight of 200KM. then the ICBM fly along mid-course phase.

During mid-course phase, the trajectory of ICBM is a parabolic curve. the starting point of the mid-course phase is at the hight of 200 KM and its trajectorypeak is about 1800 KM high. the finishing point of mid-course phase is about 80 KM high.

When mid-course phase is finished, the ICBMs is 80 KM hight and enter into "terminal phase".

洲际弹道导弹助推段达到200公里左右既进入转弯中段飞行阶段,此中段弹道曲线为抛物线,始点高度200公里左右,最高点可达到1800公里 终点高度80公里,80公里以下为再入段.

if a missle has a range of over 10000KM(ICBM), its speed during its mid-course phase is very close to firstcosmicvelocity,that is 6-7 KM/second. With trajectory rises, the accelerated velocity of warheads go slower and slower. After reaching to the 1800-KM-high trajectorypeak ,ICMBs start flying down and their speed gets accelerated again. when its enter into terminal phase at the hight of 80 KMs, its speed even surpass firstcosmicvelocity a bit, that is 20-25 Mach.

射程10000公里以上的导弹在飞行中段,飞行速度平均接近第一宇宙速度,即每秒6到7公里左右,随着弹道抬升,弹头加速度越慢,达到最高点1800多公里后随即进入中段的下降段,速度重新加快,当到达80公里再入段后,弹头速度将达到甚至略微超过第一宇宙速度,即达到20到25马赫.攻击地面目标.

for time being ,there are two estimates of CHina's mid-course interceptions,according to open news resource:

A: the interception distance is 1000+ KM and the hight of interception is 200-300 KM.

B: the itnerception distance is 2200+KM and the hight of interception is 500-600 KM.


Yankee's GBI has a interception distance of 7000+ KM and a availabe interception hight of 2000,because it is designed specially for the interception of ICBM.
China ASAT test in 2007 is about 860 KM high, so the interception high is not a problem to CHina.

What China tested in Jan 11th is in fact a mini GBI

TG这次的实验根据多方的目击者的描述和官八股实验队 以及各地相关单位的保障新闻报道, 可以确定有两个版本一个拦截距离在1000多公里 一个拦截距离在2200多公里,拦截高度也有两个版本一个是可能200到300公里 一个是500到600公里,这是根据拦截距离推算出拦截高度. 拦截时速在每秒6到7公里之间.

由于洲际导弹的弹道与运载火箭有本质的区别,运载火箭是往高了打,所以要超过第一宇宙速度,而洲际导弹追求快速进入空间最好在几十秒之内,所以追求发动机速燃技术 快速转弯横向向下抛物线投郑惯性加速度,所以一般不会达到第一宇宙速度,也不需要.

中段拦截有个最大优势可以多点步控,逐级拦截,上升段失败了,打高弹道段 高弹道段失败了 还可以打下降段.所以陆基,海基都很重要.

美国的GBI射程7000公里 拦截高度2000公里比较变态,就是这么考虑的. TG的这次实验属于迷你版的GBI 由于TG上次拦截卫星的高度是860公里,速度超过第一宇宙速度,也就是超过每秒7.5公里,所以打1000多公里的高点也不成问题. 还有一点就是能搞中段反导那么说明其发动机速燃技术 惯性导航技术 高速DSP处理器技术 姿规控发动机技术 壳体材料技术,高性能喷灌技术 大气层空气动力研究水平都达到了一个全新的高度,把这些东西用在战略导弹上其结果可以参考MD的弹道导弹攻击精度园概率偏差.

Can you find a credible news link? anyone an post an article explaining mid course interception.
specifically at what height China claims they did the interception.

 

[sayareakd]

BG based on your link it appears that the target missile of the interceptor is ICBM and you have got another interceptor which has even higher celling of interception.

 

[badguy2000]

well, guy, the writer should be a engineer majoring in missles.
I think he has explained mid-course interception quite clearly enough.

Until now, no offical news about the height of the mid course interception has be revealed yet.

So, everything is still a "estimate".

However, since it is a "mid course interception" ,it should be higher than 200 KM .

what radar is being used to track the enemy missile from the point of origin to the point of mid course flight??

 

[badguy2000]

damn, I just baidued one picture....

it is a screenshot of CCTV news...what it shows is a bit suprising!

it shows the height of the mid-course interception might be 1840 KM,much higher than any estimate. if so, the test in fact is the mid course interception of ICBM,because only ICBM can have such a high trajectorypeak.

Most ICBM'S reach a maximum 1000km height why would they test at this height?? and if they did that would mean the missile is twice as big/strong (or possibly a satellite launch vehicle)as a conventional ICBM to reach that height??

 

[sayareakd]

I am really really glad that China has conducted the present test, this will make GOI to put pressure on the DRDO to come up with better missiles (ICBM included and anti missile defence features) and ASAT weapons and they will also give green signal for its tests, which was earlier been reluctant by the GOI.

This test has made DRDO to hurry up AD1 & 2.

this test will shed GOI to give go ahead with projects necessary for national interests.

I wonder if these tests are using telemetry beacons. The Fenyung they shot down had a telemetry beacon installed. That portion is likely the last thing to fail. Since we know so little about this test except what the US said, it could have been the CCP just launching a very LEO package with a beacon on it. Since they control the test, they know exactly where it is supposed to be and with a little help from a telemetry datalink would just need minor corrections from ground control. I wouldn't put it past CCP to rig their tests, they do everything else.

I've actually tried looking to see if the missile test was WCTIS, and whether telemetry beacons were installed, but much to my chagrin have found nothing yet. I suppose we will never know until one of the (increasingly regular) leaks / releases comes out. An NTI release based on a US DoD statement says: "We detected two geographically separated missile launch events with an exoatmospheric collision also being observed by space-based sensors", but offers no further information on the event.

China has been researching ASAT / missile defense through the 863 program for a long, long time- according to this article, for atleast the last 46 years. I suppose this is only the culmination of that fruition:
???-??100??????????????????100? - aladding.com

The reason I proposed the Hq-19 was because it is consistent with the DIA Director’s reference to an “SC-19” ASAT during his testimony at the Senate Armed Services Committee in Feb '08 ('SC' being the designator for 'Shuang-cheng-tzu', and common in developmental programs). If that correlation holds, the interceptor was indeed an S-400, consistent with China's purchase of eight batteries in 2006-08.

It seems China has "semi-officialy" confirmed that the missile was an "indigenous interceptor". Ofcourse, with China everything is "indigenous", as long as they get their hands on and reverse engineer exogenous technologies:

Anti-missile interception builds shield for China's defense _English_Xinhua

Other reports, of specious reliability, seem to suggest that the missile was launched from Taiyuan, with intercept taking place somewhere near the Xinjiang/Gansu border. Atleast one chinese analyst believes that the intercept occurred with a new phased array radar somewhere in the Korla area. If this is true, and the radar appears to be bore sighted along an azimuth of close to 290 degrees as Google images near the geoocords + 41° 38’ 28.17”, + 86° 14’ 11.98” suggest, then the radar may be a modern manifestation of the joint PRC/CIA SIGINT site that reportedly was built near Korla starting in the late 1970s. See:
The Opposite End of China || Xinjiang & Northwest China Blog (?????? || ?? & ??????): August 2008 Archives

however, in fact, only USA and CHina have finished such tests.

And Russia.

Our resident shou chou seems to think he has an adequate grasp of the subject matter at hand, when in fact he does not.

I'll leave you boys to it though. Fanboy away!

The Prithvi Air Defense (P.A.D.) is the first phase of India's two-tier BMD program. It can currently, accurately be described as a mesospheric interceptor, that phase of the atmosphere where meteoroids turn into meteors. Further developments have led the PAD to improve its intercept range from 50 km to 80 km between the first and the third test. The improved missile utilizes a gimballed-directional warhead- a technology until now confined only to the US and Russia, and perhaps China. But that is not the end all. Two other interceptors are in development, and are on the anvil: called AD-1 and AD-2, designed to intercept ballistic missiles with a range of 5,000+ kms. at an altitude of over 1,500 km. First tests are scheduled for 2011.

Here, btw are pictures of those tests:

 

[iPower]

The missile test India conducted in 2006 was a THAAD, not a mid-course interceptor. Note that THAAD should have lower exo-atmosphere capability.

From South Asia Monitor: A Perspective on the Region:

The first experiment conducted last year was claimed to have achieved an exo-atmospheric interception - a rare achievement if true, as even advanced countries have struggled for years to achieve precision interception in initial attempts. Classified for the lower exo-atmosphere, the PADE, when successfully developed, might be able to match the capabilities of advanced systems like the THAAD (Theatre High Altitude Area Defence) or the Arrow-II, both of which operate at the threshold of Earth's atmosphere. While the Arrow II, Patriot (PAC-3) and Standard Missile-3 of the U.S. and the Russian S-300 and S-400 are the only systems currently operationalised for upper endo-atmospheric and lower exo-atmospheric interception, the THAAD system is still undergoing development - after 6 failures and 3 successful intercepts.

The intercept altitudes of U.S. interceptors have not been publicized, all you can find is that the tests were conducted above 140 miles, or 230 km.

The claim that only the U.S. tested true mid-course interception before China is correct.
