India has signaled that it is ready to deploy a home-grown
Ballistic Missile Defence (BMD) system in the near future with a
successful testing of an advanced interceptor missile, prompting the
defence scientists to claim a shield could be thrown over Delhi skies by
2014.
The big fireworks over the Bay of Bengal when India tested its
experimental BMD system resulted in elation as the trial turned out to
be "bang-on accurate".
The interceptor missile destroyed an incoming target missile in a
direct hit at an altitude of nearly 15 km over the Bay of Bengal,
demonstrating the efficacy of the system.
DRDO officials said the electronically simulated target, which
mimicked a missile coming from a distance of 1,500 km, was
electronically hit at an altitude of 120 km.
Within minutes of the launch of the real attacker missile, a
modified surface-to-surface Prithvi from Chandipur, Advanced Air Defence
(AAD) missile, the actual interceptor, took off from Wheeler Island and
destroyed the 'hostile' missile at an altitude of 15 km in the
endo-atmospheric mode at 12.52 p.m.
Missile technologists from the Defence Research and Development
Organisation (DRDO) for the first time tested the configuration for
destroying an incoming actual missile and another electronically
simulated missile. The score: BMD - 2, Enemy Missiles - 0.
Celebrations broke out at Wheeler Island following the success of
the mission, which was the eighth ballistic interceptor missile test. So
far seven missions have been successful and one of them, the first one
was conducted in exo-atmopshere at an altitude of 48 km in November
2006.
Defence Minister A.K. Antony lauded the DRDO scientists for the successful test.
This was the seventh time the BMD system has been tested
successfully over the last six years and promptly, the DRDO 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 said of the result from the Wheeler Island test range off
Odisha coast.
All said and done, 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 and further efforts are on to perfect them.
As soon as the target missile was launched, the Long-Range Tracking
Radars and the Multi-Functional Radars traced it and passed on the data
to the guidance computer to launch the AAD, which homed on to the
target missile and pulverised it.
In the latest BDM 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.
But both the '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," Saraswat was quoted as
saying.
"The entire test was done practically in deployment configuration," he said.
Meanwhile, DRDO 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," Saraswat said.
At present, the BMD system's phase-1, under which interceptors fly
at 4.5 Mach high-supersonic speeds to intercept enemy missiles, is meant
to tackle hostile missiles with a 2,000-km strike range.
Under DRDO's plans, the BMD phase-2 will take on 5,000-km range
missiles, virtually in the class of intercontinental ballistic missiles
(ICBM), with interceptors at hypersonic speeds of 6-7 Mach.
During the present test, Long Range Radar and MFC Radar located far
away could detect the enemy missile from take-off and tracked it
through its entire path. The total trajectory of the incoming Missile
was continuously estimated by the guidance computer and subsequently the
AAD Missile was launched at an appropriate time to counter and kill the
ballistic missile, DRDO officials said.
"The Ring Laser Gyro-based navigation system in target, Fibre Optic
Gyro based INS in Interceptor, on board computers, guidance systems,
actuation systems and the critical RF Seekers used for the terminal
phase have performed excellently," a defence scientist said.
"The AAD Missile system, initially guided by Inertial Navigation
system, was continuously getting update of the target position by the
radar through a data link. The Radio Frequency (RF) seeker tracked the
missile and on board computer guided the missile towards the target
missile and hit the target. The Radio Proximity Fuse (RPF) exploded the
warhead thereby destroying the target missile completely," he added.
In this mission, a special feature of intercepting multiple target
with multiple interceptor was demonstrated successfully, DRDO
spokesperson Ravi Gupta said.
"An electronic target with a range of 1500 km was launched and the
radars picked up the target missile, tracked the target missile
subsequently and launched an electronic interceptor missile. This
electronic interceptor missile destroyed the electronic target missile
at an altitude of 120 km," Gupta said.
"All the four missiles were tracked by the radars and all the
guidance and launch computers operated in full operational mode for
handling multiple targets with multiple interceptors. All the four
missiles were in the sky simultaneously and both the interceptions took
place near simultaneously" he said.
"This has proved the capability of DRDO to handle multiple targets
with multiple interceptors simultaneously. The complete Radar Systems,
Communication Networks, Launch Computers, Target update Systems and
state-of-the-art Avionics have been completely proven in this mission,"
he added.
DRDO Chief Controller (Missiles and Strategic Systems) Avinash
Chander, Research Centre Imarat Associate Director Sateesh Reddy and AD
Mission Programme Director Adalat Ali were present.
