In
the recent wars, we can see an identical and
regular pattern of air operations starting from
the suppression of air defences and attacks
by stealth bombers and cruise missiles to the
final strikes and bombing. We shall try to analyse
these operations.
We
shall study both the air defence ground environment
and the role of air force.
My
previous article on the same topic was more
about the ground-based air defence whereas
this article is focusing on air defence by
air force fighter jets and hence the main
theme is air superiority operations. Here
the main focus still remains the threat faced
by Pakistan due to relentless military build
up across its eastern border.
Air
Superiority Operations
Air superiority is the degree of dominance
in the battle by the air forces of one entity
over another that permits the conduct of operations
by the former and its related land, sea and
air forces at a given time and place without
prohibitive interference by the opposing air
force.
At
the outbreak of hostilities, the first battle
shall be for air superiority and outcome of
this battle shall determine the fate of battle
on land and sea. It was the victory (or tough
resistance) in the Battle of the Britain by
the Royal Air Force that Operation Sea Lion
had to be cancelled by Germany.
Lets
look at the some aspects of air superiority
operations.
In
1965 and 1971 wars, a large number of Indian
Hunters were shot down by PAF because some
of our pilots had the prior experience of
flying the Hunters and thus were ready to
face them in the war.
In
the present scenario, PAF needs to do air
combat exercises with Mig-29s of Iranian Air
Force or Malaysian Air Force to gain experience
of combat with Mig-29s. Also, air combat exercises
can be done with the Su-27s and Su-30s of
the Chinese Air Force (PLA Air Force).
Similarly,
our Mirage-3/5s can be petted against the
Mirage-2000s of the UAE or France to have
a solid understanding of the combat between
the two Mirage versions. Indian Air Force
recently did air combat exercises with French
Air Force Mirage 2000-5s and is also arranging
air combat exercises with US Air Force F-15Cs.
Exercises with French Air Force were conducted
at Gwalior in which Indians learned mainly
about BVR (Beyond Visual Range) combat and
air-to-air refuelling.
The
Royal Australian Air Force (RAAF) F/A-18 Hornets
carried out air combat exercises with the
Royal Malaysian Air Force (RMAF) Mig-29 Fulcrums
and the RAAF was forced to upgrade their Hornets.
Su-30
has the endurance of chasing the hostile fighter
up to its air base as USAF P-51 Mustang fighter
did in WW II over Germany. The P-51 Mustang
changed the whole scene of air combat over
Europe. Also the Mirage 2000s, Mig-27s and
Jaguars have been fitted with air-to-air refuelling
adapters to be used in conjunction with IL-78
tankers.
Refuelling
capability means that now Indian Air Force
can shift its fighters deep inside India and
PAF shall have to conduct deep strike missions
to attack those air bases. Deep strike mission
means a long flight in the hostile airspace
and the apparent need for refuelling or conformal
fuel tanks.
How
to deal with long endurance, high agility,
eight to ten air-to-air missiles, IRST system
and Israeli ECM equipment of the Su-30 is
the task of the Combat Commanders School (CCS)
of PAF like the US Navy, which established
Top Gun School during the Vietnam War to train
its pilots against fast and manoeuvrable Soviet
fighters. But dealing the Su-30 with the present
capabilities will really be a hard nut to
crack.
IAF
Su-30s and Mig-29s shall try to stay out of
5-6 km envelope of AIM-9L Sidewinder and the
PAF F-16 and F-7P/PG fighters shall try to
close in for a kill with Sidewinders and gunfire.
It is then necessary to escape the first round
of BVR (Beyond Visual Range) missile shots.
In a hilly terrain like Kashmir, the BVR missiles
can be avoided by taking the terrain cover
and at the same time closing in on the enemy.
In
the plane areas of Punjab, an effective and
intelligent electronic warfare system can
be counter to BVR missiles and SAMs. The AA-10
Alamo fitted on the Mig-29s may be easy to
counter than the latest AA-12 Adder missiles,
which are also being fitted on the Mig-21s
and are also carried by Su-30. The advantage
of BVR missiles is that it puts the opponent
in the defensive mood, even if it fails to
achieve a kill. Also the chaff reserves are
somewhat expended before egress.
Chaff
reserves shall also be required to avoid SAMs
and to avoid BVR missile shots from pursuing
fighters at the end of the mission. At least
50 chaff cartridges should be fitted in the
EW system of the fighters. Velocity of the
chaff decreases rapidly as compared to that
of the aircraft and this relative velocity
difference is used in the guidance algorithms
of various missiles. This problem is solved
by towed decoys, which move at the same speed
as that of fighter aircraft.
The
threat of BVR missiles primarily comes from
the Su-30s, Mig-29s, Mirage-2000 and upgraded
Mig-21s.
Mig-23s
don't have a good BVR capability and old Mig-21s,
Jaguars and Mig-27s don't have BVR missile
capability. Jaguars, Mig-27s and Mig-23s will
be escorted by Mig-29s and Su-30s. Mig-29s
of IAF are primarily meant for air superiority
and air combats of F-16s and F-7s will be
with Mig-29 escorts for the most of the time
over the Pakistani territory whereas F-16
and F-7 escorts shall face Su-30s, Mig-29s,
Mig-23s, Mig-21s and Mirage-2000s over the
Indian territory.
Both
Mig-27s and Mig-23s have variable-geometry
wings that sweep back at high speed. During
close air combat, the sweep of the wings shall
give an indication of the speed of these fighters
and the interceptor pilot can use this information
in selecting suitable tactics for achieving
a kill.
Also
the rear quarter visibility (from the cockpit)
of Mig-27 and Mig-23 is not good and, therefore,
a surprise attack from the rear can be successful.
Surprise attack requires that the fire control
radar of the interceptor should not appear
on the Radar Warning Receiver of the Migs
or locking of target and then firing of missile
should take place in shortest possible time.
Mig-29s
and Su-30s are capable of performing Cobra
manoeuvre and executing tighter turns, which
may enable them to shake off a pursuing jet
and then lock on the jet from his 6'O clock.
In a high-speed chase by a PAF fighter, this
Cobra manoeuvre may provide the Mig or Sukhoi
pilot the chance for a missile shot, once
the chasing jet passes ahead. Energy fight
will be a better option than angles fight
because then the advantage of high turn rates
enjoyed by Indian fighters will not be so
effective. Executing a tighter turn also decreases
the speed of aircraft and the defending pilots
can exploit this point.
In
such conditions, the formation tactics can
be more effective as compared to one-versus-one
combat. The combined tactics of F-86 Sabres
with F-104 Starfighters in the air operations
of 1965 is a good example. Also the tactics
used by Israeli Air Force in air combat with
the Russian pilots in 1973 Arab-Israeli War
is a good example. These tactics require the
high availability of the fighter aircraft.
For fighting against a technologically superior
aggressor, nothing (or minimum) should be
kept in reserve and full potential of the
fighter arm should be employed to inflict
heavy losses on the strike force of the aggressor.
These
tactics were employed without enemy AWACS,
thus achieving the element of surprise. For
doing air combat in the presence of enemy
AWACS planes, technological superiority or
equality seems to be the only solution.
Modern
fighter jets rely on the HUD (Head Up Display)
for aiming and firing of weapons and also
for navigation. If in the air combat or during
close support, the radar or HUD electronics
are damaged, then it becomes impossible to
see the radar lock of the target and subsequent
release of weapons. At least gun and heat-seeking
missiles should be able to be operated even
if the HUD symbology disappears due to some
fault or damage. Gun can be fired if there
is some gun sight arrangement as a back up
and missiles can be fired by arrangement as
done in F-86 Sabres in 1965 and F-6s in 1971
war.
An
advantage of using these old methods (as back
up) is the surprise because the modern LCOS
gun sights are visible on the RWR of the bogey.
F-22 Raptor is designed to achieve surprise
because not only its airframe is stealthy
but also its radar is invisible on the RWR
of the bogey due to LPI (Low Probability of
Intercept) technology.
Surveillance
by Fighters
A modern fighter jet can win the battle even
if the ground radar is jammed or destroyed
because it carries its own radar. Thus the
pilot of a modern fighter jet has still got
one eye if another is lost. On the other hand,
SAMs and radar-controlled AAA shall become
useless once their radars are jammed or destroyed.
A few modern fighters can do the job of surveillance
with their powerful radars out to 100-200
km (depending on fighter type) until the ground
radar is back in operation.
The
jamming and destruction of radars will be
a likely scenario in any possible war and
thus only one thing that can keep our flag
high is the modern high-tech fighter aircraft.
Even if at some place the radar is not powerful
enough to scan the sky out to 300-400 km,
the modern fighter can help solve this problem.
The fighters can provide extended coverage
by operating at the extreme range of the ground
surveillance radar. If the radar scans out
to 300 km and the fighter out to 100 km, then
an area out to 400 km can be scanned and an
early warning system can thus be established
for enhanced security in red alert times.
In
case of Indian Air Force, the long endurance
of Su-30 gives them the freedom to launch
attacks on Pakistani targets from unexpected
directions. Only the modern fighters can intercept
the enemy from any direction, at any distance
and at any altitude, once vectored by radar.
Night
Interdictions
During previous wars, the mobility of ground
troops and transportation of supplies was
carried out in darkness at night to avoid
the threat of air attack at daytime. To the
pilot of a modern fighter jet, there is almost
no difference in day or night due to the availability
of advanced radar system. Any stationary or
moving object on ground can easily be seen
on the radar. Thus a modern fighter can carry
out ground strikes round the clock, severely
limiting the movement of troops.
In
the recent Operation Iraqi Freedom, the mobility
of Iraqi troops was severely limited due to
the overwhelming coalition air power. To counter
this threat of night interdictions, we need
modern fighters with a strong round the clock
interception capability. Round the clock capability
is imparted by modern long-range multi-mode
radar and advanced IRST (Infra Red Search
and Track) systems. Radar can be used at the
start of interception to know the initial
bearing, range, speed and heading of the enemy
jets from a long range and then the pilot
should switch over to IRST system (like OSF
system on Rafale or PIRATE on Eurofighter)
on a close range to achieve surprise. The
OSF system of Rafale also features an air-to-air
laser range finder.
Our
interdiction fighters can also be caught in
surprise inside India by Indian interceptors
using IRST system. The surprise advantage
of the IRST system can be negated if our fighters
are flying with ground radar cover. Ground
radar shall give timely warning of the approaching
Indian fighters but this cover will not be
available inside India or at very low level.
Only
AWACS can provide long-range surveillance
to our fighters deep inside the hostile territory
and also at low level, while itself operating
in the friendly airspace.
Surface-to-Air
Weapons
All radar-directed anti-aircraft guns should
be able to be operated manually if the radar
control is lost due to failure, jamming or
missile attack. For this purpose, the radar
unit should be placed at a safe distance from
the gun. A combined gun/missile system shall
be more effective because if the pilot counters
the missile, the gun will shoot him down.
If a SAM is fired on a fighter, then the pilot
should make such evasive manoeuvres that also
increase its range from the missile launcher.
If the pilot makes tighter turns such that
its range to the missile launcher decreases,
then the pilot shall face more missile launches.
The criteria for the selection of guided weapons
(especially surface-to-air) should be their
guidance system. A guidance system that is
very difficult to jam or fool by counter-measures.
Before
inducting any new air defence system, it must
be seen whether the system is able to handle
the cruise missile threat. The ability of
the present air defence systems to deal with
cruise missiles should also be analyzed. The
AHEAD round in Oerlikon guns can be very effective
against cruise missiles. The quantity of the
Oerlikon guns should be increased. We can
also expect the cruise missiles to fly at
low level in an area covered by air defences
but for the terminal guidance and subsequently
hitting the target, the cruise missile shall
attain some height before the final impact
on the target.
Defence
against cruise missiles also works against
aircraft but is different from defence against
ballistic missiles.
One
thing is crystal clear that the air defence
network on ground can function effectively
and safely only if the air force is supporting
it and is there to provide the air cover.
The SAMs and guns cannot bear the whole burden
of air attack; it must be shared by the air
force. A clear example is of Iraq. In Operation
Desert Storm, the whole Iraqi air defence
network of Russian SAMs was destroyed by Coalition
air power because Iraqi Air Force was unable
to achieve air superiority. In Operation Iraqi
Freedom, the coalition air power was in complete
control of skies and Iraqi Air Force was completely
out of the skies.
Every
air defence system has its saturation limit
and can't handle more targets simultaneously
than for which it is designed. Thus no air
defence system can stop a storm of hundreds
of cruise missiles or a shower of other air-to-surface
missiles. Cruise missiles are fired mostly
from ships, ground launchers and bombers.
An efficient air force can disable or destroy
any of these launch platforms. Ships can be
sunk or disabled by joint operation of the
air force fighters and naval submarines. Ground
launchers of the missiles can be destroyed
by the joint operation of the air force fighters
and army gunship helicopters. Bombers and
their escorts can be shot down by fighters.
Today
the precision guided standoff weapons have
made the task of air defence more difficult.
Air-to-ground weapons can be released on the
target outside the range of defending SAMs
and guns. Thus only an air force can foil
the enemy's designs.
Countering
the Anti-Radiation Missile
First, we discuss the possible methods of
countering the threat of ARM (Anti-Radiation
Missile) and methods to keep the air defence
radars and SAM (Surface to Air Missile) sites
functional.
Redundant
engagement radars for SAM sites and extra
fire control radars for radar-controlled AAA
(Anti-Aircraft Artillery) should be arranged
in most sensitive areas. In case of anti-radiation
missile attack, the first radar will be destroyed.
In a strike formation, the first wave is always
of air defence suppression, armed with ARMs.
The
SEAD (Suppression of Enemy Air Defences) and
EW (Electronic Warfare) planes shall try to
jam or destroy the radars. They may succeed
in destroying the radars, even if the radars
are shut down just before the missile impact.
The threat on the RWRs (Radar Warning Receivers)
of the strike formation shall disappear, allowing
them to continue the attack conveniently.
When the SEAD/EW formation is gone and the
strike formation is near to the target and
well within the SAM envelope, the back up
radar should be brought into action immediately
and a salvo of missiles should be fired on
it. But for the success of this operation,
the surveillance radar should remain intact.
It shall be better if the back-up radar can
do both the functions of surveillance and
engagement. If SEAD planes are a part of strike
formation, then after the launch of up to
four ARMs, the back up radar should be brought
into action because normally a fighter carries
two ARMs. Even if there are more ARMs available
to the strike formation, they can't be launched
from a shorter range.
The
operators of the SAM units should be placed
at a safe distance from the radars. Laser
Warning Receivers (LWRs) should be fitted
on the mobile vehicles of the SAM units. LWR
shall tell the crew whether they are under
attack of laser-guided precision munitions.
Laser
Radars (Ladar) can be used for the engagement
of threats. Anti-radiation missiles will also
be not much effective against Ladars. Furthermore,
many fighter jets do not have the Laser Warning
Receivers (LWR), so the surprise will be there.
A
possible technique to fool the anti-radiation
missile can be to provide one or more false
radar targets at some safe distance from the
actual radar. This distance should be determined
by keeping in view the destruct radius of
the warhead of ARM. These false radars can
be extra transmitters that operate on the
same frequency and power as that of actual
radar. Once the ARM is launched, the actual
radar can be switched off for some time and
the missile shall destroy the nearby decoy
radar. This is especially useful against Harpy
anti-radar drones. Another option can be to
keep the actual radar and all other transmitters
switched on, which shall cause confusion for
the missile in choosing the right target.
All
these tactics are sufficient for the current
generation of ARMs like AGM-88 HARM (High
Speed Anti-Radiation Missile) but the future
successor of HARM shall employ multi-senosr
guidance, thus complicating the job of a defender.
Dealing
with Stealth
The black stealth bombers usually operate
at night to avoid visual detection in daylight.
IR-guided SAMs may not be effective against
stealth bombers because of their low-IR signature
and radar-guided SAMs are already ineffective
against them. The Kolchuga radar (kind of
passive radar) can be helpful in engaging
the stealth bombers.
The
data on the bomber's bearing and range can
be obtained from a passive radar. But if the
stealth bomber does not make any radar or
radio emissions and receives target data from
another source like the E-8 Joint STARS (Surveillance
and Target Attack Radar System), then it will
create problem for the defenders.
AWACS
(Airborne Warning and Control System) is usually
used for the detection of airborne targets
and Joint STARS for the ground targets. These
high-value assets like JSTARS, AWACS and AARs
(Air-to-Air Refuellers) should be the prime
targets. The BVR missile capability with modern
fighters is also needed to shoot down these
high-value assets, which usually operate at
a safe distance with escorts.
Stealth
bombers use laser-guided and IIR-guided air-to-ground
bombs and missiles. IIR-guided munitions can
be confused by "infra-red decoys"
or "infra-red suppression". Stealth
bombers like B-2 Spirit usually carry 2,000lb
laser-guided bombs and these bombs can be
delivered from a height of 30-35,000 feet.
Stealth
bomber can't be seen on radar but its 2,000lb
bomb can be seen on the radar, once released
from the internal weapon bay. If at the start
of the war, one or two small blips appear
on the radar screen from nowhere, then a stealth
bomber has delivered its bombs and thus its
tentative location can be calculated. Interceptors
on the combat air patrol should be vectored
to this approximate location. As infrared
emissions can't be suppressed completely,
a sensitive IRST system in the interceptor
shall be able to locate the bomber from a
close distance and then a short-range missile
with a most sensitive seeker shall accomplish
the impossible mission.
Also
when the stealth bomber opens its internal
weapons bay for the release of weapons, its
doors can be detected on the radar because
the bomber is not stealth from the inside.
Defending
the Air Bases
The stealth bombers, cruise and ballistic
missiles can be used to disable the runways
and other facilities of the air bases in the
start of the war. Indian Air Force can also
launch missile attacks on our forward air
bases using SS-250 Prithvi ballistic missiles.
We must ensure that our air bases remain operational.
The use of motorway is a good option but at
least a temporary camouflaged refuelling,
rearming (only air to air armament) and light
maintenance facility should be established
on the motorway for its effective use in war
and exercise days.
All
alternate arrangements should be done and
planned for the take off and landing of warplanes
in case the runway is disabled. If the runway
of a particular air base is disabled then
air cover from another nearby air base should
be provided till the runway of the former
air base have been repaired.
For
air defence purpose, an area of at least 30
km radius should be made No Fly Zone around
a strategic site. The radius of this area
should be determined by considering the range
of standoff air-to-surface guided missiles
and bombs carried by strike formation. In
fact both Mig-27s and Mirage-2000Hs of IAF
have been modified to carry Litening targeting
pod, enabling them to stay outside the target
defences.
Traps
should be prepared for the enemy attack aircraft
like a dummy F-16, which shall invite enemy
jets into the trap. The dummy F-16 should
be surrounded by a heavily concentrated anti-aircraft
fire, positioned in such a way to ensure the
kill. But these guns should also provide coverage
to the surrounding area.
Mirages
and Super-7s
PAF has inducted a large number of Mirages.
Instead of always going for Mirage-3/5, PAF
should have considered the induction of new
or used Mirage F-1s. Mirage F-1 has superior
rate of climb, superior manoeuvrability, greater
range, lower landing speeds and shorter landing
and take-off runs than Mirage-3 or Mirage-5.
Mirage F-1C was fitted with Atar 9K-50 and
Mirage F-1E was fitted with M53 engine instead
of old Atar engine, giving it a far superior
performance than Mirage-3/5.
The
Super-7 is a joint project with China but
still its radar, powerplant, avionics and
weapons shall have to be procured from other
sources. Although design and development of
just airframe is not a big accomplishment,
but it is certainly a step towards self-sufficiency.
A valuable experience from this project shall
be the integration of various systems and
technologies.
China
is itself procuring hi-tech fighters from
Russia and has acquired Su-27SK and Su-30MK
fighters from Russia to counter the Taiwan's
hi-tech F-16C and Mirage 2000-5 fighters.
Super-7
can be used to replace the oldest Mirage squadrons
but it can't fulfil the requirement of a new
fourth generation fighter to fill the technological
gap. Super-7 does not seem to be in the class
of Rafale, Eurofighter, F-16C Block 50+, F/A-18
Super Hornet,
Mig-29SMT,
Su-30MK and Su-35/37 Super Flankers.
Recently
a news item reported that Pakistan might get
F-16s. Even if the USA agrees to deliver F-16s,
they should not be accepted just with AIM-9L/M
Sidewinders. These are missiles that make
kills and fighter is just a platform for releasing
them. These aircraft should be at least F-16C
Block 50/52 with AIM-9X Sidewinders, AIM-120C
AMRAAMs, AGM-88C HARMs and AGM-154 (A,B,C)
JSOWs. Other weapons include GBU-15s (with
TV and Flir cameras), AGM-130s, BLU-109s,
CBU-87/97s, AGM-65Gs, GBU-24s (Paveway-3 series),
Sniper targeting pods and latest ECM equipment.
The
best deal shall be for the F-16C Block 60
with conformal fuel tanks and internal FLIRS
(Forward Looking Infra Red Sensors) for night
attacks. But who shall ensure a smooth supply
of spares for aircraft and its weapon systems?
Selection
and training of fighter pilots
Only those candidates should be selected for
GD(P) who have a strong fighter flying aptitude.
Enthusiasm for air warfare is more crucial
than medical fitness. Even cadets from the
PAF College, Sargodha and Lower Topa should
not be selected without checking their interest
in air warfare. Anyone interested in fighter
flying and air warfare shall search and study
any available literature on that topic.
In
this computer age, we also have a lot of realistic
flight simulators available in the market
and an interested guy shall certainly try
them and learn a lot from these simulators.
Therefore, real interest in fighter flying
can be judged by assessing the knowledge of
a candidate about various fighter planes (at
least of PAF) if not about air operations.
Lackadaisical pilots perform better only in
the peacetime.
Even
the recognition of various fighter aircraft
is impossible without interest. Without interest,
a pilot would not be able to recognize fighter
planes even after many years of service and
with interest even a youngster would identify
various fighters, bombers, trainers, cargo
and passenger planes.
Fighter
pilots must recognize all military aircaft
of the world and this skill is essential for
avoiding fratricide in close combat. Apart
from recognition, only an interested person
shall know and remember the performance limits
of various fighter aircraft and characteristics
of their weapon systems.
Advanced
training in various air operations like air
defence suppression, interception, interdiction,
close air support, escort and anti-ship missions
should be conducted more frequently so that
the ratio of highly skilled pilots (Top Guns)
can be increased.
Night
air operations over different terrains like
mountains, seas, deserts, plains and plateaus
should also be conducted by the night-capable
squadrons. Night air-to-ground operations
can be conducted only by those fighters that
have modern avionics and radar system with
air-to-ground radar modes and terrain-following
functions.
Night
interceptions are also important because Indian
Air Force can switch to heavy night operations
if it meets tough resistance from PAF in daytime,
so we must be prepared.
Su-30MKIs, Jaguars, Mirage 2000s and Mig-27s
shall be used for round-the-clock strikes
and our F-16s, F-7P/PGs and upgraded Mirages
for round-the-clock interceptions.
