Lessons from the Bekaa Valley


The tale of the air war over the Bekaa Valley has only improved with time and with telling. It was definitely a spectacular operation but right from the start various slanted lessons have been read off the operation. It will be noted that the Israelis themselves have often said that its lessons cannot be generalized.

 

This  assessment is based on a selection of analyses done by various agencies. The references are given at the end. I have based as my source a official analyses by Col. Dubrov writing in the Aviytsiya and Kosmonautica on the lessons of the war and a commentary on the same by Dr. Benjamin Lambeth writing for RAND. Both these journals can be considered “Government” and being “Government” have the merit of being true though by no means should they be considered as the whole truth. Governments cannot afford to work that way.  A possible factor none of the reports mention was the contribution of the terrain of the Bekaa Valley. It appears to me that the terrain of the Bekaa Valley was a very important contribution to the final results and makes the operation” unique” rather than “general”. These I have discussed.

 

Various claims and predictions have been made about the conflict from the Israelis having invented a secret weapon to the fact that the Bekaa Valley triggered the collapse of the Soviet Union to even  Bekaa Valley being a proof that third generation  fighters cannot survive against fourth generation aircraft. This is too general in their assumptions. The Bekaa Valley combat is a question of particular importance to the India whose design skills were “bonsai”-ed by successive Governments from the late sixties till recently and yet we have to have adequate numbers of adequate warplanes.   

 

 What I have done is to read through the reports and then filtered out what I thought were obvious biases. Military reports often have a strong “marketing” angle to them. Rather than “the latest technology” i.e. unaffordable warplanes winning the war it was the traditional qualities- diligence, carefulness, training, thoroughness, objectivity and planning which the Israelis displayed over a sustained period- a decade to be precise-paid rich dividends whilst reckless courage –which the Syrians displayed in abundance- did not get the Syrians anywhere. It does not mean that if the Syrians had the same qualities of careful planning as the Israelis the loss ratio would have been reversed but even with the “hand” the Syrians had the loss ratios would have not been quite so stunning and the Syrians could have given the Israelis – who are poorly placed to take casualties- quite a bad fright.

 

For India the lessons are that we have to evolve our own strategies. Ignoring numbers to concentrate on quality would be as sure a way to defeat as to rely solely on numbers. If you enjoyed the first Kung Fu Panda movie you will remember that the secret of the Magic Scroll was that there was no secret and no one will teach you any which way– you have to “figger” out the secret of the Wu Xi hold yourself!

 

 

 

The Yom Kippur War

In the Yom Kippur War of 1973 the Isr.A.F. suffered horrendous losses to the then new and largely unknown SA 6. The flat Sinai terrain allowed the tracked launchers room for maneuver as well as presenting the aircraft as a clear high contrast target. The flat launch trajectory of the SA6 was also of no problem.  Under ideal conditions for the SA 6 system it was devastatingly  effective and the total Isr. AF losses in the critical first 72 hours was 50 aircraft ( Israeli figures) and 59 as per the Egyptians the total losses over the 18 days air war was 109 aircraft. How many fell to what system will not be known because amongst other things the Isr.A.F. mentions all losses as “combat loss” or if they are feeling particularly talkative that day, “due to ground fire”. Air to Air losses, like the PAF are almost never acknowledged.

 

Surviving the near mortal losses the Israelis prioritized two lessons.

i)                    They focused on the development of tactics to neutralize the threat posed by the tracked SAMs. In this they were aided by the Americans who had a direct interest as NATO forces would encounter the same missile systems were they to engage in hostilities with the USSR. By 1978 i.e. after about five years the Israelis cautiously declared that they had the measure of the SA 6 threat. By May 1980 the Israelis were able to “field test” their solution under actual conditions when they destroyed two SA 9 launchers but waited patiently for a suitable opportunity both tactical and political.

ii)                   They also built up their number of combat squadrons from 14 squadrons to 21 squadrons which included helicopters for the CAS role. This building up of air Strength is noteworthy for India and it is a process that must have taken about 5 to 7 years to reach maturity because of the training time.

  

The Bekaa Valley shootout

The details of the operations are widely available; what is given here is a summary. Syria had involved itself in Lebanon in support of the PLO and in the early ‘eighties. It had moved its SA 6 batteries into the Bekaa Valley to protect its forces in Lebanon following the shooting down of two of its helicopters by Israeli F 15s. In June 1982 Israeli forces invaded the Lebanon after informing Syria that they had no intentions against the Syrian forces and were after the PLO and would penetrate 40 kms into Lebanon. Apparently Syria accepted the conditions and moved its forces out of the way. When they exceeded that limit the Israeli advance was halted by a Syrian armoured division at the River Jazzine on the night of 8-9 June 1982. Israel then saw that as an opportunity for its plan to take out the SA 6 Batteries. The Armed Forces, which had been inexact about the excessive advance- 40 kms- from where had not been precisely defined-,  and emphasizing that taking out the SA6 batteries was crucial to the safety of the Israeli armoured division under Syrian attack. They also assured the Israeli Politicians that given its preparations, careful planning and homework its losses would be minimal. Political Sanction was given by 1000 hrs of 9th June 1982 but the strike was postponed due weather conditions over Bekaa and the need to update information. The strike was finally unleashed on the SAM sites at around 1400hrs.

 

The strike consisted of aircraft at three levels.  It will be of note to India that Second/ Third generation airframes with third generation avionics e.g. Kfirs/Nesher and upgraded Skyhawks provided CAS at sea levels. Further aircraft were stacked in “cab ranks” at 3000 mts and at 9000 mts were the Boeing “jamming” aircraft and the E2A’s AWACS used to direct the strikes.  The Syrians apparently withdrew their combat air patrols but by 1420 hrs the Israelis attacked the EW Radar at Jebel Barick .The Syrians reacted with fighters about an hour later but without any plans and were shot down flight by flight as they blundered blindly against the Israelis who could monitor, thanks to the use of IAI UAVs, each flight almost as soon as they took off and had jammed their communications.  At around 1550 the Israelis went in for the SA 6 sites using HARM , Shrike and similar standoff missiles mounted on F 4s. The F 16s and F 15s were not tied to close escorts but were employed in the “free hunt” mode with the F 15s also being used as mini AWACs to cover the gaps in coverage. At its peak there were up to 90 Israeli and 60 Syrian aircraft in the conflict zone of about 40kms and 40 kms. Having first “blinded” the guidance radars with ARMs the SA 6s were destroyed all by cluster bombs in a very short time- reputedly about 20 minutes because of the up to the minute knowledge of the SA6 positions. No LGBS were used because the Israelis deemed them to be too slow.

 

The Losses

The figures usually quoted for the Bekaa Valley shootout are about 85 to 87 Syrian aircraft shot down for no losses for the Israelis. Unfortunately both the Air Forces are extremely “cagey” about revealing anything and these figures, as with the Soviet official figure of 60 Israeli losses must be taken as untrue and for respective domestic consumptions. The history of estimation of air combat losses shows that the enemy’s losses are always difficult to estimate even given the best of intentions and intentions are not always the best. In the Battle of Britain the RAF claimed destroying 178 Luftwaffe aircraft on an occasion when the actual German losses were 45. Things really did not change substantial over time. So what were the actual losses?

 

 The claim of 87 losses means that there were 87 situations when the Israelis thought they had shot down or destroyed a Syrian aircraft. Since the fighting was taking place over territory that was Syrian held it would be difficult to verify the claims.  The Syrian admission of 50 losses and 18 pilots (Note 1) are likely to be nearer to the truth.

 

The Israeli losses are – and I am going only by my readings on the subject - would have been around ten to twelve. Of these three, two A4s and a Phantom F4 have been confirmed (by the Syrians) by photographs of the wreckages and the rest must have been caused by the formidable AAA at Bekaa Valley. Whatever their lacunae in terms of planning, the Syrians “stuck to their guns” (literally!) and it would be incredible that the “dumber” weapons 2X23 and 4X23 mm AAA did not “damage beyond economical repair” (delightful PAF phrase to describe the second Sabre that Flt. Lt. Cooke filled up with ball ammunition over Kalikunda on 6th September 1965). This is not to belittle the Isr.A.F achievement because 50 kills for wastage of 12 aircraft i.e. 4:1 is enviable.

 

 

 

An analysis of the results

The Bekaa Valley shootout has been used to sell everything from the “latest and best” fighters to, I am fairly sure, some variety of malted chocolate milk! My conclusions are somewhat different. Bekaa Valley confirmed more than anything else the traditional qualities of Military Planning- a mastery of one’s own weapons and a thorough knowledge of the enemies’, careful planning, patience, and numerical superiority( to be noted,please!), training all played apart. As always the element of surprise and the first mover’s advantage is also to be noted. The Bekaa Valley shoot out was an aerial Commando raid brilliantly choreographed.Thanksto diligent planning when it came to the actual fighting the Israelis were shooting fish in a barrel. Below are some salient points we should note:

 

The terrain

None of the analysis mentions anything about the terrain. One can conclude it played no part but this goes against common sense. A Topographic Map of the Bekaa Valley by the geologist A.S.A. Lateef ( presumably no relation of “Late” Lateef of Indian Folklore!) is included and shows the contours with the usual practice of the heights being shown to a different scale as compared to the distances. The Bekaa is a rift valley with two ridges rising to peaks of 2800 mts and a gap of around 16 kilometers between the ridges. Being a geological map showing rock compositions the ridges are not shown to the full height, The Bekaa ridges were fairly narrow at the top which and the Batteries located on the top of the ridges were very restricted in their mobility and even in their placement.  The North - South orientation of the ridges meant that the EW Radars located in Syria and  Lebanon were blinded by the ridges and any radar located in Lebanon, Bekaa, and Syria were isolated by the ridges from looking into the other two areas and those located on the ridges were sacrificing their mobility for the sake coverage whereas the Isr.AF EW stations could look into and up the valley. The fighting was confined to a very small “bowl”. What advantages it gave to the jamming which was a big contribution to the success  or how the opposite ridge wall may have disadvantaged the SA6s tracking radars is something the electronics people with knowledge of clutter suppression abilities of the respective radars in such a situation will be better able to explain but it must have been a factor.

 

The Distances

A second feature was the relatively short distances of the airbases of both the combatants from the Bekaa Valley. Typically they would be within 80 to a 100n.m. of the Bekaa the greater ranges of the US warplanes meant that they could loiter over the battle area and were able to give instant support where ever needed.

 

AWACS

The Israelis were using at least two of their four E2 Hawkeyes and these were operating well above the battle at around 9000 mts and away on the seaward side looking right down into the arena. This was supplemented by the powerful radars of the F 15 which supplemented any “blind spots”-possibly caused by the ridges. The Israeli set up and maintained an imaginary threat line and any Syrian flight that crossed that line was destroyed, the Israelis sending in their forces appropriately.

 

The missiles

The Israelis used the AIM7F Sparrow, the AIM 9L Sidewinder. Some sources mention the homegrown Shafrir but this could be a marketing effort. All the IR missiles were capable of “head on” attacks. The Syrians were using the Atoll which had very restricted launch parameters.

 

The Syrian mistakes

The SA 6s were mounted on tracked vehicles to give the Soviet battle groups instant air cover. Mobility was also part of its repertoire for survival. Using it on the ridges of the Lebanon ( Jabil al Libanon) and Anti Lebanon ( Jabil al ash Shariki)  mountains meant that mobility was severely compromised. The SA 6s were literally “sitting ducks”. The Israelis knew exactly which holes to ferret and accounts for theswift destruction of the SA 6 batteries. Indeed, having suffered from the SA6 in the Yom Kippur war they treated the SA 6 with informed respect, delaying at the last minute their strike until two batteries which had moved around a village were located.

 

 When “baited” by flights of IAI drones the Syrians reportedly switched on all their radars thus revealing their position and confirming them to the ELINT aircraft. This sounds something out of a Leon Uris novel but if true the Syrians deserved what they got.

 

MiG 21 SMT avionics

It is fair to describe the MiG 21 SMT as a third generation airframe with a second generation avionics suite. The MiG 21’s avionics permitted only front and tail warning from its Sirena RWR and the Israelis who were dominating the agenda fed in its fighter streams to make beam attacks so the Syrians had no inkling that they were being painted even just prior to an attack.

Jamming

Jamming of attacks is nothing new. The RAF used “Headache” which was simply a microphone in the engine nacelle of the bomber and broadcasting on the frequency of the Luftwaffe’s fighter control frequency. Very soon the Luftwaffe rigged up a simple device which would home onto the jamming i.e. they would fly to where the jamming was the strongest.

 

 Homing on the Jamming would have passed the initiative of the battle over to the Syrian because the Israelis would have to move to protect the foundation of its attack strategy. Indeed the Israelis used two F 15s as close escorts to protect it “Jammer” at all times. The Syrians should have anticipated heavy jamming once the Hey Avir got the Boeings and the E2s but obviously they were resting on their laurels or relying on blood and guts to see them through. They paid the price.

 

The jamming of communications completely disrupted and demoralized the Syrian efforts. It was possibly the key factor in blunting the Syrian response as the pilots were cut off from their GCI. In desperation they were seen to fly around in figure of eights trying to obtain visual contact until they were shot down. “It would not have mattered what aircraft they were flying because the way they were flying they would have been shot down anyway” said one Isr.A.F. Senior planner. Again the confined spaces in which the battle was going on would mean that the jamming would have been particularly effective- as a thumb rules the jamming declines as the square of the distance.

 

The idea I am trying to propound is that with more “thinking” on the part of the Syrians and with small upgrades to their MiG 21 s and other equipment the Syrians could have got much better results.

 

 Lessons for India

The Lessons for India are somewhat different than those discussed above.

 

The Russo Japanese War of 1903-4 threw up all the lessons that were os grimly learnt in the First World War. The 1973 and Bekaa Valley and even the recent Balakot episode is a microcosm of the losses that modern technology can cause.

 

Our lesson will be the horrendous losses we will suffer in the opening phases of any serious conflict and the need to stay in the fight so that we can “give it back”. Our ability to “Give it back” and not the initial losses, will be the decider. The estimates could be anything between 80 to a 100 aircraft lost due to all causes and another 100 damaged to various degrees in the first 96 hours before we could come up with the counter tactics. It will be noted that the Bekaa Valley ended on the third days before Syrian counter strategies, if any, could be brought into play.

 

This loss rate means that of the ten to twelve squadrons on a particular front will have been worse than decimated. They will need replenishment/retraining and, possibly, rotation. We need a larger air Force and the 50 squadrons.  I have written about is not just a round “Parkinson”-ian figure. Even the archaic 42 squadrons will not be sufficient and the inevitable sacrifice of the aircrew will have gone in vain just as the attacker’s advantage will have been evened out. Ideally we should have the latest and the best equipment for these fifty squadrons but the economy cannot sustain that. We would “Pakistan” ourselves very easily. Imports would be very uneconomical in every way.

 

We are therefore today facing a choice about how we are going to be inadequately prepared. Either we have a small excellently equipped and trained air force that will be very sensitive to losses or we will have a larger well equipped Air Force but whose training and serviceability may suffer. The maintenance cost of equipment is usually two to three times the procurement cost.

However within the convolutions of the Bekaa Valley lies our answer. It will be noted that:

 

i)                    None of the platforms used their “end of the aerodynamic performance” limits. No one pulled 9G and more importantly none of the two hundred aeroplanes went supersonic let alone Mach 2. The Balakot fight reconfirmed this aspect.

 

ii)                  The “all weather” equipment did not perform under all weather conditions. Strikes had to be postponed according to the weather. If this was the case in the Mediterranean how much worse they will behave under Indian Monsoon.

 

 

iii)                What did the Syrians really need to have evened out the losses substantially?  Not too much. Not new platforms but well thought out upgrades. Jam proof communications, HMDS, some electronics – on special few aircraft to home on the jamming- this would have tasked the Israelis to protect their Boeing Jammer. Let me expand the idea.

iv)                 I am putting a deliberately provocative proposal. Suppose “the Syrians” had a platform with the capabilities of the MiG 17/Mig 19 in terms of top speed etc i.e something between a second and a third generation airframe.  The chances would be zero i.e. the same as the “better” MiG 21 “the Syrians” used. But the force would have been cheaper to buy and maintain!

v)                   To that add jam proof communications. Would the kill ratio have improved?

vi)                Then add to that the R 73/R60 what then?

vii)                Now put in a HMDS what would have been the kill ratio picture?

 

Soon we will get a picture of a relatively simple aircraft  tailor made for a clear well defined threat scenario –like ours- which is within the reach of our Industry and costing a fraction  of a Mach 2 type. This is a ”zero based” specification for a fighter general combat (F-GC) type.You are referred to the items 7 to io in the references list.

 

The basic gaming we should do is what better minimum equipment and tactics should “the Syrians” have used so that the kill/loss ratio became unacceptable to “the Israelis”.

 

I have put “the Syrians” and “the Israelis” within inverted commas because “the  Syrians” could be us in a future conflict. We are still relying on imported supplies and the best that is available rather than what is more tailored to our need and therefore cheaper.

 

We have chosen a very wise mix of MKI/ MMRCA/LWF aircraft to meet our air defence needs. We must maximize the flexibility and the economies this mix gives us to get the large air force that we need but cannot afford.

 

Guided weapons and AI are putting the onus of performance on the missiles and the aircraft is continuing to be more of a platform than ever before. The Wst having developed the Mach 2 platforms are continuing to use them as thebasis for their future aircraft but there is no need for Mach 2 or even Mach 1.4. We have to evolve a comprehensive doctrine to see how we can cobble a credible deterrence to any threat using whatever technologies that we have developed e.g. the LCA with more range and better transonic handling rather than overpowering it to reach the Mach 1.6 speed and super cruise. The role of the fighter is changing with the maturing of guided missiles and development of electronics and artificial intelligence. I insist on the transonic regime i.e. less than Mach 1.3 because aircraft in that regime can be significantly smaller, longer ranging and cheaper than something even at Mach 1.4- Mach 1.5 and what is more completely within our present technological capability including the required engine technology. I do not believe that we will get any engine technology by any collaboration. Even if we did we would not know what to do with it because the “know why” will not and indeed cannot be taught.  Suppose we are given a certain combustor technology-will we use it for reducing smoke signature or reduce the engine weight? The Chief Designer’s contribution is his vision and surefootedness in knowing why he is making a particular choice out of the multiple choices. How good are we at that? What is our work culture to rapidly experiment and come to a near optimum? A  project that takes decades to come to service may be heroic to some but it is of no use, not even technology generation because the technology is obsolescent. Weapons development is not just science. We have an admittedly weak base in this.

 

Having selected the correct “three class” fighter formula the whole will unravel unless we make the LCA type the cornerstone of our numbers. This would be a transonic airframe with reduced radar (not full stealth- because it is beyond us, the performance penalty is too much and is probably a May laurel- it won’t last!) and IR signatures but with fifth or sixth generation information and display systems and using homegrown VFR missile systems and operating under AWACS and ADGES an area in which we seem to have made hopeful progress. The transonic performance will also reduce the technology demand on the engine.

 

THE Bekaa Valley Air Operations was a commando operation: violent, effective but unlikely to be repeated. The real lesson is the likelihood of severe losses for the “defence” and how to absorb them and still remain in the ring. Also to be able to “asymetrize”  the warfare. It was possible for the Syrians to have done much better and foiled the Israelis with greater losses which would have been good enough. The reasons for not doing so will never be known because it would have been relatively easy. Perhaps for the highly politicized Arab Armed forces this was not possible.

 

Note

Of the Syrian losses claimed by the Isr.A.F., 40 were claimed by the F 15s and 44 were claimed by the F 16s and one fell to a F4. The gun fire kilss are contradicted by the Israeli sources themselves possibly as a matter of policy. One source said onlyabout 7% of the Syrians fell to the guns i.e. about 6-7 aircraft whereas another sources rather equivocally talked of “surprisingly large number of gun kills.”

Amongst the Syran pilots lost was their Ace of Aces Major Bassam Hamshu ( 8 kills including one n the ground in earlier clashes ) and Col. Fayaz Mansour ( 4 kills) who was shot down in a”friendly fire “ incident by a Syrian tank using its 12.7 mm AAA.

 

Note

Each Syrian SA 6 battery consisted of one “Straight  Flush” fire control radar , four SA 6 launcher each with three missiles and two ZiL 131  six wheel re- supply trucks. Thebatteries are controlled by a Long Track surveillance rdar and a thin Skin height fining radar.
