India test-fires ballistic missile interceptor

India tests missile shield, DRDO says it will be operational by 2014

NEW DELHI: There were some big fireworks over the Bay of Bengal on Friday afternoon when India tested its experimental ballistic missile defence (BMD) system to intercept two "incoming hostile" missiles with interceptor missiles.

Elated with the "bang-on accurate" test, the seventh time the BMD system has been tested successfully over the last six years, the Defence Research and Development Organization (DRDO) promptly declared a missile shield could be deployed for New Delhi by 2014.

"We are now ready to convert the BMD system from an experimental to an operational one that can be deployed on demand. I am confident we can deploy the Phase-I of the BMD system by 2014," said DRDO chief V K Saraswat, speaking to TOI from the Wheeler Island test range off Odisha coast.

But the reality check is that even American missile defence systems like Patriot Advanced Capability-3, Aegis BMD-3 and THAAD (terminal high-altitude area defence), as also Russian and Israeli ones, are not fully foolproof as of now.

In Friday's test, only one of the incoming missiles was real: a modified Prithvi missile mimicking M-9/M-11 class of Chinese Dong Feng short-range ballistic missiles. The other was an electronically simulated missile of a longer range of 1,500km.

Both "enemy" missile launches were, however, conducted "in the same window" to test the BMD system's capability to handle "multiple threats" simultaneously. "This has been done only by the two superpowers (US and Russia) till now. The real missile was destroyed at an altitude of 14.7-km by the interceptor missile with a direct hit," said Saraswat.

The electronic missile was intercepted at an altitude of 120km. Both the missiles were picked up and tracked by long-range and multi-function radars, which in turn passed the data to guidance and launch computers of the interceptors to "kill" them. "The entire test was done practically in deployment configuration," he said.

While it remains to be seen whether DRDO can indeed deploy an effective missile shield by 2014, it has also begun work on adding a third tier to the BMD system. The existing two-tier system is designed to track and destroy ballistic missiles both inside (endo) and outside (exo) the earth's atmosphere.

The third layer is planned to tackle low-flying cruise missiles, artillery projectiles and rockets in the line with the overall aim to achieve "near 100% kill or interception probability".


"Look what is happening in the Middle-East (Hamas firing rockets at Israeli cities before the recent ceasefire)...hence, protection against low-cost, very close range threats is also needed. We have begun some initial work on the third-tier. We will try to integrate it with the BMD system once it fructifies," said Saraswat.

At present, Phase-I of the BMD system, with interceptors flying at 4.5 Mach high-supersonic speeds to intercept enemy missiles, is meant to tackle hostile missiles with a 2,000-km strike range.

As per DRDO's plans, Phase-II will be geared for taking on 5,000-km range missiles, virtually in the class of ICBMs (intercontinental ballistic missiles), with interceptors at hypersonic speeds of 6-7 Mach.

India's ballistic missile shield: DRDO: 2, Enemy missiles: 0

Here at Geek at Large we like to follow the Defence Research and Development Organization's (DRDO's) ballistic missile defence program (BMD) rather closely. More than once in the recent past the organization has said that as far as India's long range ballistic missile programs and missile defence programs are concerned, the country is both self-sufficient as well as proficient. Today's twin intercepts - one actual and one simulated seems to attest that view.

In one of the two tests conducted today, DRDO's AAD endo-atmospheric interceptor achieved a radio proximity fuse triggered explosive intercept on a target missile derived from elements of the Prithvi short range ballistic missile (SRBM) family. Do note however that this target missile is modified in a manner that allows it to re-enter at an angle of attack and at a velocity usually associated with medium range ballistic missiles (MRBMs) which are faster given that their apogee is greater. In fact that is precisely what this Prithvi derived target missile also does in order to attain the velocities required to simulate longer ranged missiles.

Near simultaneously an exo-atmospheric test was also conducted albeit electronically to confirm the intercept of an electronically simulated ballistic missile launched from 1500 km away thereby demonstrating a salvo interception capability. The second intercept was achieved at an altitude of 120 km, which is pretty significant given that the United States Air Force (USAF) hands out 'astronaut wings' to its personnel if they happen to find themselves at an altitude of more than 80 km above mean sea level. 120 km is also a shade over the so called 'Karman line' which defines the boundary between the earth's atmosphere and outer space as being 100 km above sea level and this metric is accepted by the Fédération Aéronautique Internationale.

However international legal norms also define the lower boundary of space as the minimum altitude at which an orbit around the earth can be sustained. This is apparently 150 km for an unpowered space vehicle and 130 km for a satellite with propulsion. Why do these definitions matter? Well, it may be the case that a non-proliferation treaty (NPT) for limiting the weaponization of space on the lines of the nuclear NPT (NNPT) is in the offing. The relationship between such a treaty and the existing outer space treaty is a matter of conjecture but India cannot afford a repeat of what happened vis a vis the NNPT in the sixties. That of course does not mean that we necessarily go about blowing up apparently defunct satellites in outer space as the Chinese and Americans have done. But India should nevertheless make it clear that India could if it wanted to.

The successful twin tests were apparently done in a deployable condition which means that the rollout of the AAD as a deployed entity may happen soon. The AAD intercept shows that Indian seeker technology has now matured and the exo-atmospheric test is representative of DRDO's progress in ground based radar technology. Indeed, according to DRDO 'The complete Radar Systems, Communication Networks, Launch Computers, Target update Systems and state of the art Avionics have been completely proven in this Mission'.

It is no wonder that the Americans want to collaborate closely with India to track space debris. DRDO is apparently planning more exo-atmospheric tests which will look to demonstrate intercept capability at an altitude of 300 km. After that, I don't think anybody would be able to keep India out of any future 'Space NPT' hypothetical or otherwise.

The flex nozzle at work


hi everyone! finally joined the forum!!
I don't think the interceptor changed direction acutely. the IR track locked on the incoming prithvi at the last moment because it was radiating more heat signature. IMO flex nozzle won't work so late. the interceptor was cruising passively, so no thrust vectoring! anyways gr8 day for drdo. congrats everyone.

The tracker may have locked onto Pritvi but without vectoring the thrust, no misile can maneuver so quickly
while travelling at high-supersonic speed.
 
That 14 seconds burn time was enough to destroy a ballistic missile at 15 km above earth!!! BTW FOR YOUR KNOWLEDGE THE SURFACE TO SURFACE VERSION OF THIS MISSILE PRAHAAR HAS RANGE OF 150 KM. :smokin:

Even Akash SAM has max altitude of 18km. And can intercept cruise missiles like CJ-10, Babur & Ra'ad.

Yes. AAD has max altitude of 30 km. It is a long range missile, can sustain much longer than Akash. Akash can intercept better at lower altitude specially cruise missiles and UAVs.


Did any of the desi journos managed to get info about PDV? Or they just asked how it will perform against M-11????

The interceptor does not use IR homing, its radar homing in the terminal phase.
 
^^ right, it has RF seeker, not IR...
I was talking about the ground IR tracking system that was locked on AAD to track progress of AAD... it locked on incoming prithvi, and may be created illusion that AAD also moved acutely onto prithvi... AAD was cruising with motor offline in last few seconds, so can't use thrust vectoring.
