The target missile, a modified surface-to-surface 'Prithvi' was first lifted off from a mobile launcher at 10:05 am from the launch complex-3 of ITR at Chandipur-on-sea, 15 km from here.
The interceptor "AAD" missile, positioned at Wheeler Island, about 70 km across sea from Chandipur getting signals from radars tracked it a few minutes later and than intercepted at a definite altitude in the mid-air over the sea, the sources said.
Defence Research and Development Organisation (DRDO), today successfully conducted fourth consecutive Interceptor Missile test in Endo atmospheric regime at 15 Km altitude off ITR, Chandipur, Orissa. The single stage Interceptor Missile fitted with Directional Warhead and other advanced systems neutralized the target.
The target ballistic ‘enemy’ missile was launched from Launch Complex – III, ITR Chandipur. The Interceptor Missile fitted with directional warhead was launched from Wheeler Island and destroyed the Target Missile breaking it into fragments. This was tracked by various Radars and sensors. All weapon system elements including Command and Control, Communication and Radar performed satisfactorily.
The Defence Minister Shri AK Antony spoke to DRDO Chief Dr VK Sarswat over phone and congratulated the scientists for today’s successful test.
An "AAD" missile was used as interceptor at low altitude, the sources said, adding that the indigenously developed new hypersonic interceptor missiles was designed to be engaged in endo and exo atmospheric condition.
hain DDM, or any truth to this?? An hypersonic BMDS, means they could modify it further and implement it on other platforms to intercept "Hypersonic CRUIS Missiles" as well!!!

T.S. Subramanian and Y.S. Mallikarjun in the Hindu on today’s test launch of the AAD.
Reports that a “P-charge directional warhead”, whatever that is, was used for the first time in the AAD.
Also used in the AAD were electro-mechanical actuators and a ring-based gyro navigation system though the article is not clear if this was used for the first time:

^ true, he leaves all those uppity and truely profusive in his effusives
>>Reports that a “P-charge directional warhead”, whatever that is,
Within a few metres of the modified Prithvi, the warhead exploded releasing multiple bullet-like particles which hit and destroyed the target missile
http://www.drdo.res.in/labs/tbrl/achieve.html
Multi P-charge based warhead with two layers using simultaneous system for anti ship role.
Multi P-charge based warhead suitable for wide area mines for defeat of convoys and isolated landing sites
TSP is testing a dung-e-khairaat tomorrow so they must have notified the GOI, I hope we track it using the LRTR (Sonmiani test site falls under its coverage)
Yes, projectile charge, infact they should have notified as multi P-charge directional warhead. It effect is similar to firing several gatling guns simulatenously on the target from the interceptor missile. Any journos if given a chance must ask how this will effective against hardened RV.

One wonders how these projectiles are powered and stabilized? explosive ejection of rods with individuals spinning? Or are they just ball bearing type, thrown as narrow an arc as possible?
Regarding hardened RVs. I would assume these little ones will shove the RV off the track and probably induce tumbling and other uncool stuff.
I wonder, if I am right in reading that, yellow track is that of the 'enemy' and undulating blue track is that of the AAD (undulating track suggestive of terminal homing manuevers?). Red dot indicating AAD fragment carrying its transmitter and blue dot indicating 'enemy' transmitter (contained in a fragment that is continuing on its original path due to inertia)

No ball bearing type. Its like many Shaped charges aligned and directed; stabilized by the gimbaled platform. I think it will be bullet like. It will be like stream of metal jets hitting the target missile.
Regarding the yellow/blue plot, I think it might be the other way, the yellow being AAd. The yellow line might be continuing, because the gimballed part might still be intact after the projectiles go out. Whereas the blue is all torn up after a certain time. The red might be the point where the command to pop the cap came.

hanir, that is indeed a possibility.
Reading more into the plot, looks like, 'enemy' was encountered after a tail-chase rather than being ambushed head-on.
This is a good test. Having a credible BMD keeps us much safer. Am sure we can ignore the hypocrites who questions the credibility of the defence. If the enemy indeed dares a missile attack against us , and our BMD beats the missile. Imagine the shit enemy is gonna fall into. Total retaliation from Mother India

And I might be wrong, but apparently, a certain amount of "fragmentation" of the target happened BEFORE the red dot (assuming the red dot means something)..... Really cool, that the red dot exists next to the Lal Mullah not with the burqas he threw out

The yellow track appears to be the target missile.
Didn't we see similar plots in earlier tests (with a large fragment of the target following the original trajectory)?
Wheeler Island (Orissa): A few heart-stopping moments were witnessed before celebrations broke out in the Mission Control Room here on Monday, as the telemetry link was lost in the final seconds when the Advanced Air Defence (AAD) interceptor missile hit the target missile (a modified Prithvi).
Anxious wait
Confusion reigned for a while over the success of the mission. There was stunned silence and an anxious wait to know the exact outcome.
Since plasmas play havoc with radio waves, its possible that as the AAD approaches the enemy missile, especially in a tail chase (lower relative velocity), the rocket exhaust plasma from one missile shields the radio waves emitted by one or both missiles - depending on the location of the telemetry earth station with respect to the the missiles.
Israel's military has begun constructing a third battery of long-range, high-altitude Arrow anti-missile interceptors near Tel Aviv to boost defenses against Iranian ballistic missiles.
The planned deployment, and a scramble to develop and install other systems to counter short- and medium-range missiles and rockets, underlines the Jewish state's growing fears that its cities and towns face a missile bombardment of unprecedented scale and ferocity.
The existing batteries of Arrow-2 interceptors, jointly produced by state-owned Israel Aerospace Industries and the Boeing Co., are deployed at an air force base in southern Israel and another near the city of Hadera in the north.
Additional batteries are expected to be added over the next decade.
"The new battery provides another layer of protection and gives the air force the ability to launch more than one interceptor at an incoming target," The Jerusalem Post quoted a senior Israeli officer as saying Thursday.
The new battery will be controlled by the Citron Tree fire-control command center developed along with the Arrow over the last two decades. It will also control the other two batteries now in place.
"It will be able to control all of the other batteries from the new position so if there's a malfunction at the other sites we have a backup," the senior official explained.
"In general, the new battery helps us disperse our assets and enables us to continue operating defense systems even if some of the other batteries are damaged during a conflict."
IAI and Boeing are developing an advanced Arrow-3 missile under a program that began in 1988 and has absorbed around $1 billion in direct U.S. funding.

Yes the yellow line is the BM with a straight ballistic fall and the blue is the AAD , the fragment are post the hit.
Apparently in GW 1 the Iraqi Scud used to bread down due to poor work manship and the body of the missile used to breakup due to stress while the warhead used to fall , it was not possible to discriminate the warhead and fragment caused for the radar as they broke into many thousand pieces of metal creating a metal ball clutter for the RF.

I remember reading something completely different - the Patriot missile (GW1 version) was quite useless. Often the Patriot succeeded in breaking the incoming scud while leaving the warhead intact, which simply dropped after the interception and exploded on the ground anyway.

That was 2nd part of the problem , this was the problem with detection and tracking by Patriot radar or for that matter any radar will face this problem if it encountered , the best example is AAD radar tracking the multiple debris after sucessful interception. The problem Patriot faced was the same debris before interception because the missile bodies broke in mid air at high altitudes.
