With
the Aero India 2005 in full swing the IAF would do
well to take a look at the European MBDA
Consortium’s Meteor
BVRAAM, suggests our analyst Sayan Majumdar.
The
European MBDA Consortium has made persistent offers
to integrate the Meteor
Beyond Visual Range Air-to-Air Missile (BVRAAM 80+
nautical miles range) with the Indian Air Force (IAF)
Sukhoi-30MKI fighters. The present Russian BVRAAMs
like R-27 (AA-10 Alamo) and RVV-AE (AA-12 Adder) in
service with the IAF Sukhoi-30s and MiG-29s are also
in service with the Chinese Peoples Liberation Army
Air Force (PLAAF). Thus their performance spectrum
would be compromised to a potential adversary, which
is bound to “relatively blunt” the effectiveness
of these otherwise excellent AAMs to a certain
degree.
Meteor
is slated to enter operational service by 2010 and
as MBDA has hinted on a technology transfer
arrangement, this project is bound to have a
positive impact on the indigenous light (150-kg,
80-km range) Active-Radar Homing (ARH) Astra BVRAAM
project, guided and led by the Hyderabad-based
Defence Research and Development Laboratory (DRDL).
Born
out of the multi-national Project S225X examining
the future BVRAAM technologies such as ram-rocket
propulsion, two way data-links, dual-band and
dual-type seekers, stealth technology and improved
resistance to Electronic Counter Measures (ECM),
MBDA Meteor
sports a stealthy, low drag, lightweight body with
two wings mounted centrally on the upper body and
four fins mounted at the rear. The missile radome
encloses the MBDA/Thales X or Ku-band radar seeker
following the “fire-and-forget” Active Radar
Homing (ARH) mode.
Meteor
is capable of engaging air targets autonomously,
whether fighters, bombers, transport aircraft, AWACS
or cruise missiles by using its active radar seeker
by day or night and in all weather or dense EW
(Electronic Warfare) environments. Meteor’s
solid Boron fuelled Variable-Flow Ducted Ram-rocket
(VFDR) propulsion system will ensure a range well in
excess of 100-km and a speed of more than Mach 4 and
high terminal velocity. Thus even when launched from
extreme stand-off ranges, the missile will have the
energy in the end game to defeat fast, manoeuvring
targets. The need for controlled airflow to the
ramjet ducts ruled out the “skid-to-turn”
manoeuvring of a conventional rocket-powered
missile, as it will risk masking an intake and
instead “bank-to-turn” manoeuvring is adopted.
To ensure total target destruction, the missile is
equipped with a combination of SAAB Dynamics laser
proximity and impact fuzes and a fragmentation
warhead that is detonated at the optimum point to
maximise lethality.
For
mid-course navigation guidance Meteor
utilises Inertial Navigation System (INS) combined
with information provided by the launch, or any
friendly aircraft via the two way data-link, to
adequately offset Identification Friend or Foe (IFF)
complexities or challenges. During the terminal
phase the active-radar homing method employs
advanced proportional based navigation software. It
can receive targeting data after launch from the
launching fighter, another fighter, or Airborne
Warning & Control Systems (AWACS) platforms. The
two-way data-link partially solves the IFF problem
at long ranges.
Since
IFF remains a problem because of incorrect and
absent returns and "spoofing", AWACS
platforms are presently deployed for reconfirmation
of enemy airborne targets at extended ranges and in
this respect the IAF will naturally be benefited by
induction of PHALCON AWACS platforms. The fighter
pilots need not follow the risky
"eyeball/shooter" sequence any more, where
the flight leader comes unacceptably close to the
enemy formation for positive identification and
passes the data to other fighters to fire the
BVRAAMs.
In
the long term, work is in progress for development
of electro-optical seeker technology coupled with
on-board threat database that will let the missiles
themselves determine the legitimacy of the target
and this seems to be the logical option. Whether
this futuristic option is being considered for the Meteor
Project is not yet certain.
However
Meteor is sure to “posses” provisions for the futuristic
concept of “Cooperative Fighter Operations” or
Mixed Fighter Force Concept (MFFC) that is essential
for future BVR engagements and optimum performance
and results. Pairs of aircraft will be data-linked;
as one illuminates the other launches the missiles
against the targets. In such engagements the
“striker” fighter will be able to impart the
greatest kinetic energy to the Meteor
BVRAAM by accelerating up to Mach 2 and then
manoeuvring out of the engagement. The illuminator
fighter such as the Sukhoi-30MKI with powerful radar
capable of performing like a mini-AWACS would remain
firmly subsonic keeping a decent distance from the
target, and providing either command-guidance
updates or illuminating the target. The IAF have
absorbed the MFFC well and superbly demonstrated his
during Cope India 2004 air exercise with the United
States Air Force (USAF).
Hitherto
our indigenous anti-aircraft missile development
have repeatedly encountered technological
complications and thus close cooperation with the
European Consortium MBDA, the manufacturer of Meteor
high-performance BVRAAM will prove to be beneficial.
The protracted delay in attainment of Initial
Operational Capability (IOC) of anti-aircraft
missiles like Trishul and Akash are partly because
of absence of joint-cooperation with an established
foreign manufacturing consortium.
This
mistake should not be repeated during development of
Astra especially as MBDA now enjoys very close
relationship with the Indian defence industries. As
USAF officials have hinted, the sophisticated MBDA
MICA BVRAAM already “silently” serves under the
wings of IAF Mirage 2000s with suitably updated
radars. A transfer of technology arrangement in
relation to the Meteor BVRAAM may prove to be the
optimum logical step. Subject to critical decisions,
in the long run the Meteor
and Astra BVRAAM may complement the Russian
ultra-long-range (400-km+) R-172 BVRAAM and R-73RDM2
or possibly Israeli Python 4/5 Near Beyond Visual
Range/Within Visual Range (NBVR/WVR) AAMs in the
IAFs formidable and fearsome AAM inventory.
