More than 200 Sukhoi Flankers currently form the core of the
Indian Air Force’s strike element, for a planned force of over 272 Su-30
fighter-bombers. India received the initial batch of Sukhois in 2002. The first
of these aircraft crashed in 2009, and since then five more have crashed.
Now let’s look at the Sukhois in other air forces.
The People’s Liberation Army Air Force (PLAAF) has 150 Flankers of Russian origin and 229 Chinese knockoffs. That’s a total of
379 aircraft, for an eventual figure of 400 Russian made Flankers, derivatives
and illegal copies. And yet the PLAAF has lost fewer Sukhoi in crashes. Are the
Chinese Sukhois better maintained, better built or are Chinese pilots simply playing
it safe? More on that in a moment.
The Russian Air Force has a total of 438 Flankers. Again,
the Russian Sukhois don’t tumble out of the air at a rate close to the IAF’s. Similarly,
there have been no reports of Flankers of the Vietnamese and Indonesian air
forces being involved in crashes.
Why the Flanker force
matters
The IAF calls the Su-30 its “air dominance” fighter for a
good reason. The arrival of the Sukhoi has decisively tilted the balance of
power in favour of the IAF in the region. The Flanker’s super-maneuverability,
its armoury of advanced beyond visual range missiles and extraordinary range of
3000 km (extendable to 8000 km with aerial refuelling) are aspects that make it
the wolf of the skies.
The Su-30 is also equipped with synthetic aperture radar
(SAR), which gives it greater long-range reconnaissance capabilities. Armed
with the SAR pod, the IAF Sukhois are known to engage in aggressive patrols
along the China-India and India-Pakistan borders.
Considering the Flanker’s hunter killer reputation, anyone
who questions its capability is clearly living under a rock.
So what explains the loss of six IAF Flankers in crashes?
Let’s go into the various probable causes and also dissect the theories
floating out there.
Crash No.1: 30 April
2009
The first ever Su-30MKI crashes in the Pokhran region,
Rajasthan. The IAF’s Court of Inquiry establishes Wing Commander Vishwas Munje
mistakenly switched off the warplane’s fly-by-wire system.
Crash No.2: 30
November 2009
Sukhoi crashes near Jaisalmer, Rajasthan, after a fire
warning. An IAF investigation attributes it to accidental ingestion of a
foreign object in the engine intake.
Crash No.3: 13
December 2011
Aircraft crashes 20 km from Pune. IAF says the crash is due
to a malfunction in the fly-by-wire system.
Crash No.4: 19
February 2013
Aircraft’s right wing explodes over Pokhran, shortly after
completing a training mission.
Crash No.5: 14
October 2013
Fly-by-wire system malfunctions yet again and the Sukhoi
goes down near Pune. Russian experts blame pilot error but the IAF says the
Court of Inquiry is yet to pinpoint exact reason.
Crash No.6: 19 May
2015
Su-30MKI flying from Tezpur in Assam develops a technical
snag and the pilot is forced to abandon the aircraft. Cause is yet to be
established.
Now that you have a good idea of what exactly happened in those
six crashes, let’s look at the possible reasons why jet fighters crash in
India.
Possible reason No.1:
Intense training
The IAF is one of the few air forces in the world that
conduct intense, year-round training. Benjamin Lambeth of the Carnegie
Endowment for International Peace says the IAF trains for a "high
intensity, high stakes" conflict. Keeping in mind the possibility of a
two-front war, the IAF puts its pilots and aircraft through the wringer.
Mock air combat can involve hundreds of aircraft flying
thousands of kilometres. During such a war game in 2013, Sukhois flew 1800-km bombing missions from Chabua in Assam to the
western front, with mid-air refuelling. In fact, IAF pilots are known to lead
missions over 10 hours in their Sukhois.
Such training places a great deal of stress on aircraft,
pilots and air crews, which means potentially more accidents. But that’s the
way the IAF trains for war. In fact, a former air force chief has gone on
record that he would rather lose pilots during training than during war.
The strategy has been amply rewarded. In the 1971 War, for
instance, the IAF was able to conduct a wide range of missions – troop support;
air combat; deep penetration strikes; para-dropping behind enemy lines; feints
to draw enemy fighters away from the actual target; bombing; and
reconnaissance.
In contrast, the Pakistan Air Force, which was solely
focused on air combat, was blown out of the subcontinent’s skies within the
first week of the war. Those PAF aircraft that survived took refuge at Iranian
air bases or in concrete bunkers, refusing to offer a fight.
Similarly, the PLAAF has nearly 2,000 planes, but only a
fraction of the peace-time accident rate. According to Foreign Policy, this suggests Chinese pilots are not spending sufficient time in the air or
training under pressure. “(Chinese) pilots are neither trusted nor properly
trained. Drills are regimented, centrally controlled, and divorced from
realistic combat conditions.”
A PLAAF fighter pilot would most likely be reprimanded if he
deviated from the flight plan set by his commanders. Losing a plane would be cause
enough for a court martial.
Thankfully, the IAF does not believe in having robots but
values superior training and innovativeness. IAF pilots have truly internalised
what Sergei Dolgushin, a Russian Air Force ace with 24 victories in WWII, said
is a prerequisite to be a successful fighter pilot: “A love of hunting, a great
desire to be the top dog”.
Possible reason No.2:
Harsh environment
Harsh is normal in India. Tropical India is an unforgiving
environment for any aircraft. The hot air means aircraft engines produce less
thrust and the wing produce less lift compared to similar aircraft flying in
European skies. Sun baked runways are also known to impact landing safety.
These are factors IAF pilots have to live with.
Bird hits are another huge factor in aircraft accidents over
India. The IAF
attributes around 10 per cent of accidents to bird hits. Most IAF bases are located near populated areas,
where birds are a constant menace.
The situation has got so dire that the IAF last year issued
global bids to four companies for 45 bird detection and monitoring radar
systems to be installed at airports and air bases across India.
Possible reason No.3:
Missing trainers
According to figures released by the Ministry of Defence in
March 2013, the IAF was losing the equivalent of one fighter squadron (approximately
18 fighters) in accidents every two years. This was primarily because of the
lack of adequate number of trainers.
Rookie fighter pilots begin on basic trainers, then move on
to intermediate jet trainers (IJTs) before finally graduating to advanced jet
trainers (AJTs). These three stages are critical elements of fighter pilot
training and any shortcuts will certainly lead to disaster.
But what was happening was that in the absence of an AJT,
rookie pilots were moving straight from the IJT to frontline warplanes such as
the MiG-21. The upshot – young pilots died at an alarming rate.
With the induction of the Swiss Pilatus basic trainer and Hawk
AJT from Britain, the crashes have come down – but not stopped.
Possible reason No.4:
Shoddy maintenance
India is notorious for its ‘chalta hai’ or ‘it’ll be
alright’ attitude. In this backdrop, shoddy maintenance could well be a factor.
Although the IAF is known for its high standards, those standards are largely
of its pilots; maintenance crews may not share that quality. Of late, there
have been a number of incidents reported widely in the media about IAF ground
crew involved in all sorts of serious crimes. The IAF should look at establishing
an elite division of ground crews to service its high-end aircraft.
Possible reason No.5:
Depleted air force
The IAF’s fleet strength is currently down to 34 squadrons
or around 600 warplanes. The sanctioned number is 42 squadrons. In a country as
vast as India, with multiple threats, such depletion in fighter aircraft means fewer
aircraft have to perform more missions to get the same job done. It also means less
down time in maintenance hangars. This is where India quickly needs to induct
more locally built Tejas interceptors and more locally assembled Su-30s.
Silver lining
The good news is that aircraft crashes in the IAF have shown
a declining trend over the last three years. From a high of 30 in fiscal
2011-12, they declined to six in 2012-13 and an equal number in 2013-14.
The IAF is now looking to improve overall fleet
serviceability. The air force recently told a parliamentary committee that
fleet-wide serviceability stood at 60-65 per cent, but could be increased to
77-80 per cent, provided spares were made available.
During a visit to Bangalore in December, IAF chief ACM Arup
Raha said: “Budgets remain a constraint, especially the revenue budget, to
maintain spares for the aircraft to maintain high operational readiness.”
While the IAF is clearly doing its best under the
circumstances, it needs to do better. Bringing the crash rate down to US or
European air force levels should be the goal. Losing a Sukhoi each year is akin
to burning Rs 350 crore in cash.
