      根据印度媒体报道,4月27日上午印度的大气层外拦截弹PDV首次试验获得成功,这是PDV导弹的首次试验,印度的第一阶段反导系统至此已经全部进行了试验,未来PDV再进行一些试验后,基于PDV和AAD的印度第一阶段反导系统有望开始正式部署。

kktt画的图,试验范围
 
当时想当然的以为拦截成功了,看到这个官方通报还很奇怪,为什么不说成功拦截呢,而只说实现了试验目标呢
DRDO的官方报道:

Maiden Launch of PDV interceptor
In a significant milestone achieved in the direction of developing a two layered Ballistic Missile
Defence system, DRDO today successfully carried out the maiden PDV mission meeting the mission
objectives
. PDV mission is for engaging the targets in the exo-atmosphere region at about more than
120km altitude.
Both, the PDV interceptor and the two stage target equipped with motors were specially developed for
the PDV mission
. The target was developed for mimicking a "hostile Ballistic Missile approaching
from more than 2000 km away" was launched at 0907 hrs from a Ship in the Bay of Bengal.


In an automated operation, radar based detection and tracking system detected and tracked the
enemy's ballistic missile. The computer network with the help of data received from Radars predicted
the Trajectory of the incoming Ballistic Missile. PDV that was kept fully ready, took-off once the
Computer system gave the necessary command for lift-off.
The Interceptor guided by high accuracy Inertial Navigation System (INS) supported by a Redundant
Micro Navigation System moved towards the estimated point of the interception. Once Missile
crossed atmosphere, the Heat Shield ejected and the IR Seeker dome opened to look at the Target
location as designated by the Mission Computer. With the help of Inertial Guidance and IR Seeker
the Missile moved for interception.

All events were monitored in real-time by the Telemetry/Range Stations, at various other locations.
The mission was completed and the interception parameters were achieved.
Shri Avinash Chander, SA TO RM and Secretary Deptt of Defence R&D congratulated the mission
team. Dr VG Sekaran, DS & DG MSS; Dr Satish Reddy Dir RCI; Shri Adalat Ali, Program Director AD,
Shri Y Sreenivas Rao RCI project Director AD; Dr PS Goel DRDO chair former chairman RAC; Shri
Venu Gopal former Director DRDL; Shri MVKV Prasad Director ITR, Dr Tessy Thomas OS &PD A4
and other senior DRDO officials were present.

PDV拦截弹首次发射,不过没能拦截目标

毕竟么,印度媒体开始是这么报道的:

India successfully test fires new interceptor missile

India on Sunday successfully test fired a new interceptor missile capable of neutralising any incoming long-range missile at higher altitude.

The interceptor, positioned at launch pad-IV of Integrated Test Range at Wheeler Island, about 100 km from Balasore, Odisha, roared into the sky at about 9.10 a.m. to hit its target.

The target, mimicking an incoming enemy missile, was first test fired from a naval ship at 9.06 a.m. and after getting signals from the radars, the interceptor went into action.

“The trial was conducted successfully and all the mission objectives were met,” Defence Research and Development Organisation (DRDO) Spokesman Ravi Kumar Gupta told PTI over phone.

The details of the ‘kill effect’ of the interceptor missile were analysed after retrieving all the data from various radars and telemetry stations, an official said.

Earlier DRDO, which is the premier agency to develop such a sophisticated interceptor, had successfully tested six interceptor missiles developed by it, both in endo-atmosphere (within 30 km altitude above sea level and exo-atmosphere stage (above 30 km altitude).

The Prithvi Air Defence interceptor missile has already demonstrated its killing capability at an altitude of 50 km and 80 km while the Advanced Air Defence interceptor missile has smashed the target missile at an altitude of 15 km to 30 km.

Now the target is to achieve the interception at an altitude of above 100 km of a long range missile, defence sources said.


后来thehindu的进一步报道揭了老底:

原来并没有实现拦截,到底拦截弹与靶弹之间的距离到底是多少还不知道,当然导引头成功的发现和跟踪了目标,所以,试验取得了成功

虽然他们说这次试验不打算引爆PDV的弹头进行拦截,但是.....看专家被记者逼问的窘样,实在不像啊

Scientists say Prithvi Defence Vehicle mission achieved important objectives
India’s ambitious mission on Sunday to intercept an “enemy” ballistic missile at a altitude of 120 km seems to have achieved only partial success. While the missile technologists of the Defence Research and Development Organisation (DRDO) say the interception did take place and the mission met its “important objectives,” they concede that the warhead in the interceptor missile, which took off from the Wheeler Island, did not explode.

Avinash Chander, Scientific Adviser to the Defence Minister, said: “The infrared (IR) seeker in the interceptor could track the target, but we have not exploded the target. The target was not to be exploded.”

Asked if the mission was only “partially successful,” Mr. Chander, architect of India’s Agni series of missiles, said, “The mission’s main objective was to track the target missile. We wanted to see the performance of the IR seeker. The warhead in the interceptor missile was not meant to be exploded in this mission. Since we did not fire the warhead, the debris did not fall.”

Another DRDO missile technologist said: “We have recorded the interception.”

Asked whether “a hit-to-kill” took place in the mission as it did in the previous six other interceptor flights from the Wheeler Island, he said: “We have to work out the missed distance between the target missile and the interceptor. Based on that, the hit-to-kill would take place. We are not able to say right now whether the hit-to-kill took place.”

Yet another scientist said, “Whether the target missile was destroyed or not, I cannot say right now.”

The DRDO was looking forward to this mission because it was “challenging” and “complex.” Of the DRDO’s seven interceptor missions, six were successful. The interceptions had taken place either in the endo-atmosphere (below 50 km) or in the exo-atmosphere (between 50 km and 80 km).But this mission was a different ball game because the interception was to be done at 120 km, providing very little time for the interceptor to blast off and waylay the attacker. So the motors in the interceptor called the Prithvi Defence Vehicle (PDV) and the target missile were specially developed. The target missile lifted off a ship in the Bay of Bengal, off Odisha at 9.07 a.m. It was a two-stage missile, “mimicking a hostile ballistic missile approaching from more than 2,000 km away,” a DRDO press release said.

In an automated operation, radar-based systems on the Wheeler Island and in Paradip, Puri and Cuttack detected and tracked the “enemy” missile. The computer network, with the help of data from the radars, predicted its trajectory. The single-stage PDV interceptor took off two-and-a-half minutes later.

The PDV, guided by the highly accurate inertial navigation system and supported by a redundant micro-navigation system, moved towards the point of interception. Once the PDV crossed the atmosphere, its heat shield domes covering the IR and radio frequency (RF) seekers fell off. So the two seeker domes opened to look at the incoming missile’s location. With the help of inertial guidance and the IR seeker, the PDV moved for the interception. “The mission was completed and the interception parameters were achieved,” the press release said.

G. Satheesh Reddy, Director, Research Centre, Imarat , a DRDO missile facility in Hyderabad, said the mission featured several new technologies. Both the missiles had new, powerful motors. The heat shield, covering the IR and RF seekers, ejected for the first time. The seekers worked well. “This is the first time that an imaging seeker has been used for the air defence vehicle. The imaging seeker could see the incoming missile, track it and guide the interceptor towards the target.” The RCI team made the seekers and the inertial navigation and guidance system, Mr. Reddy said.

Adalat Ali was the Programme Director and Y. Sreenivasa Rao, Project Director.
