It is an unpaved runway. But its a very long one. And often, as I've written on this very forum, these "unpaved" runways were custom built in the United States and one in Australia to allow C-17 "unpaved" practice. But they are built to a standard that would support even the heaviest of heavy jets.

In the United States, in Canada and in Australia, where there are thousands of civilian unpaved runways, the C-17 NEVER lands in any of them, because it would destroy them if it did.

That is why they make "special" "unsurfaced" runways where they practice. And none of these are only 3500 feet long, although anyone who talks about the C-17, including two different people on your Dover Air Force base video, claim that "it can land on 3500 foot runways"
It is not the question of long or short unpaved runways. Just see the video and the distance that it takes to come to a halt.

Now why would C 17 blow up if they landed on US, Australian or Canadian unpaved runways? I have missed the logic, it appears.

And what is the requirement of a C 17 to land on any runway when it does not have a task/ mission there?

Facts or videos would speak better.

Further, why has the IAF graduated to bigger aircraft carrying more payload than the earlier one? From Dakotas to Fairchild Packet to An 12 to An 32 to IL 76? Because it is economical to run, service and maintain a smaller number of aircraft delivering more payload!

That apart, if one aircraft can drop or airland what four smaller aircraft would do, it means that this aircraft is less time over the combat zone than having four aircraft landing as per the safety dispersion and longer over the combat Zone.

In a para drop exercise with AN 32s in Ladakh a few years ago, because the aircraft were flying in formation and owing to sudden crosswind, the aircraft behind the one from which the paratrooper had exited veered. In the bargain the paratrooper was cut to smithereens by the rear AN 32. Had they jumped from a single IL 76, such a thing would not have happened.

Imagine this type of things happening in war where the safety regulations are not that high as in peacetime paradrops!!

Also, in war, the Commander would like to have all his paratroopers dropped in one pass so that the dispersion is limited.

I would be really surprised if any Army or Air Force would make 'special'/ ideal unpaved runways. After all, one trains for war and not for demonstration.

I have no axe to grind and so the issue is merely academic for me. However, I am commenting from the military point of view and nothing else.

For instance, a Master Green does not become one without graduating from one degree of expertise to the next more difficult degree and so on till the highest degree of difficulty. And there is no special or ideal way one can achieve to become a Master Green. And to continue to hold that, he has to go through the ritual at regular intervals.

OK, lets look at another scenario.

If at a post the enemy is making headway and there is a requirement for reinforcement, landing many small aircraft at the ALG would be better or having one aircraft that lands everyone and their equipment?

Remember, every minute counts and the men and equipment landed put get into position and combat readiness at the earliest. The equipment could be tanks, troops, artillery piece etc.

Would the delay of each small aircraft not count compared to one big aircraft landing all?

With all humility I would state that money should not be the criterion to decide what is required. It is the use of an equipment to further the efficiency of fighting a war if it is imposed on us.

One could say, why have an AWAC since it is so expensive. Or why have an Arihant, when many German U2s could be refurbished and scour the seas!

And interestingly, we debate so intensely that we must abandon the INSAS and have foreign cosmetically enhanced weapons to serve the same purpose! However, if the INSAS is lousy, then it must be stated upfront why it is so and why the foreign weapon is better!

I have seen comments that INSAS is not suitable for CI. Who says so and why? How is it that with the INSAS itself we have been able to curb the terrorist when there were no great weapons of foreign origin around.

What weapon was CApt Jass' men having? It saved him or did it do any better than the INSAS?

In the demonstrations on the videos, the aircraft are empty and very light on fuel. Ask them to do the same with an M-1 Abrams tank in the hold and 5 hours flight worth of fuel in their tanks and they need 7000 to 8000 feet of runway.

Its the gravel runways that get destroyed by the C-17, not the other way around. They create huge ruts in the touchdown zone and in the roll out area due to heavy braking.

The C-17s are made to land on gravel runways, but the gravel runways are not made for the C-17 :D

You have experience of the same and were you there when the videos were made?

If with M 1 they require 7000 to 8000 ft runway, I would surely be delighted to know so, and may I quote you that you have witnessed such an event?

Have you flown in a C 17 or IL 76? I have flown in IL 76s many a time.

I would be immensely surprised if the US Army or Airforce would accept a fraud demonstration, more so since they are having cold feet these days about their lives because of Iraq and Afghanistan.

I would be equally surprised if the IAF selects an equipment that does not fit the bill as per the claims made by the manufacturers! OK. You may feel that the defence forces are chumps, but the little that I saw of them, I don't think they are total fools. I cannot say what happens at the MOD and the Govt levels.

I hope you are aware that on any runway, the take off and landings add to wear and tear and they have to be maintained?

Why do you think a jeep moves up and down a runway to check for slicks and ruts whenever a take off or landing takes place?

Have you seen an ALG and what it takes to maintain it?
The C-17s are made to land on gravel runways, but the gravel runways are not made for the C-17 :D
If the gravel runways are not made for specific aircraft. Point is?

How about come comments on the military aspects mentioned by me? Or are they superfluous and immaterial when buying equipment?

An airlift is the organized delivery of supplies or personnel by aircraft.

Airlifting consists of two distinct types, strategic and tactical airlifting. Typically, strategic airlifting involves moving materiel long distances (such as across or off the continent or theatre), whereas a tactical airlift focuses on deploying resources and material into a specific location with high precision.

Depending on the situation, airlifted supplies can be delivered by a variety of means. When the destination and surrounding airspace is considered secure, the aircraft will land at an appropriate airport or airbase to have its cargo unloaded on the ground. When landing the craft, or distributing the supplies to a certain area from a landing zone by surface transportation is not an option, the cargo aircraft can drop them in mid-flight using parachutes attached to the supply containers in question. When there is a broad area available where the intended receivers have control without fear of the enemy interfering with collection and/or stealing the goods, the planes can maintain a normal flight altitude and simply drop the supplies down and let them parachute to the ground. However, when the area is too small for this method, as with an isolated base, and/or is too dangerous to land in, a Low Altitude Parachute Extraction System drop is used.

Let me explain the value of having a large aircraft with an Indian example.

In the J&K War just after independence, IAF had One Squadron of Dakota light transport aircraft with seven aircraft.

With the help of civil Dakotas they barely were able to lift a Brigade in waves.

Now, if they had larger aircraft than Dakotas, then more troops, equipment, artillery etc would have been inducted early enough. This would allow the Indian Army to move towards Barmullah faster and stop the Pakistanis and they could not have reached Badgam on the outskirts of Srinagar! Being at Baramullah, the Pakistanis would have been pushed further back in the same timeframe if the Indian Army stopped the Pakistanis at Baramullah and not Badgam!

I took a closer look and became suspicious when I noticed that the tank was so far forward in the cabin. In an Il-76, such a heavy load would have been installed right underneath the wing spar, which is not visible in this picture...

This Russian T-90 is actually inside an An-22.......

Sorry............
Amazing catch

Just for comparison, here is a An-22 (possibly exact same one)

According to http://www.chapman-freeborn.com/cargo/cargospecs.aspx

An-22 width: 430 cm

Well I did link you to the account on PPRUNE of the guy who loaded a Challenger 2 on a C-17, but the point here is that there is no doubt the C-17 can easily accomodate both the T-90 and Arjun.

On the other hand there was (and is) significant doubt that a T-90 could fit on an Il-76 because it is wider than the T-72 which is already 'challenging' to load on an Il-76.

Gilles wrote:The difficulty in loading the T-72 inside the IL-76 was because instead of having an engineering team work on developing a technique of loading and unloading the tank into the aircraft and writing an instruction manual on how to perform the task (as the US did to load the M-1 Abrams into the C-17), the IAF flight crews had to improvise a method through trial and error
Er, no. The difficulty (as elucidated in the article) was that 1) it could only be driven partially into the plane, then had to be carefully winched (with frequent pauses and realignments) further in and 2) there was so little margin for error, tank drivers had difficulty getting their tanks lined up exactly center

In contrast, the C-17 loading procedure is very simple:
1) drive tank in
2) chain it down

Actually, airfields are not too hard to put out of commission. Without enough level space for an aircraft to take off, an airfield is no better than an agricultural field.
1. An airfield is much easier to defend as it is only one small place as compared to trying to defend thousands of miles of rail

2. Airfields are very hard to KEEP out of commission, temporary repairs can be done very quickly.

Road and Rail allow you to transport enormous amounts of men and material at very cheap rates and quite effeciently when compared to air transport. A C17 can transport 1 tank, while a train can transport a battalion at less cost!

The question then is NOT "why have air transport at all? " but rather "What role should air transport play in the overall logistical picture ?"
Ok, what role should air transport play in the overall logistical picture? (in other words, why even bother to have air transport?)

(Rail is good and all, but saying you can only go where the rail goes is a very dangerous limitation)

Since we've already established that the Il-76 is unsuitable, the only real question from India's point of view is 'Can the An-124 do as well in short/rough field operations as the C-17?"

Thoughts on the An-124 tomorrow . . .

>>>Let me explain the value of having a large aircraft with an Indian example.

But we have a comparable aircraft already in service. The question is not whether IAF would like to have a bigger aircraft - It is about whether the new aircraft being proposed is worth the price, looking at its utility.

From what I can see, there are ofcourse differences between the two aircrafts in question, but may not justify the huge difference in price, along with the added risk of an unreliable supplier, lifetime costs, availability of spares as the production is likely to stop after executing pending orders etc.

Initially the talk was how this new a/c ca lift a tank ..then it was about how short a runway it requires. But all these can be performed by IL-76 as well, though may not be exactly. But then, if you invest the same money on IL-76, we can probably have 3-4 times the number of aircrafts, which would be a better option IMO.

Personally, I feel this deal is being pushed down the throat, and the victim is blissfully opening its mouth to the maximum extend possible.

Let’s not feel that there is a conspiracy in every military deal. Though I don’t blame anyone for the paranoia after the Bofors issue!

If one compares IL 76 and C 17, they are not in the same league. I have appended enough details for a comparative analysis. I have also given the military reasons why a bigger aircraft from anywhere in the world is essential.

Price? So why have an Arihant? That will cost a hand and a leg! Let’s save money by leasing from Russia nuclear subs, more so since quite a few feel that Russia will never impose sanctions on India! To be frank, whatever foreign equipment India acquires, unless we have licence production, there will always be the threat of the Nation selling that equipment will look after its own National interest and not that of India.

If price was the sole criterion, then we should have nothing since everything is expensive.

And why waste so much of money for the Moon project, when we will gain nothing from it except to feel that ‘been there, done that’ feeling and in the Big League?!

Why have Prithivi and other missiles? Why hanker for the Patriot missile or even the Barak?

The answer is when there is defence requirement, then the price is not an issue. The safety of the Nation is! We require to have a lift capability to move troops and equipment at short notice and strength in the shortest possible time and in the most economical manner. A bigger aircraft means more payload and is more economical. Just calculate the costs for the same payload of IL 76 and the C 17.

Indeed, an airlifter should be capable of lifting not one tank, but many and also arty piece. And at one go land the maximum feasible if one is to spearhead a military action that requires reinforcement in equipment or troops.

The short runway issue is because on the border one requires to have a basic runway to save expenses and other issues that I will not discuss.

Of course, we can have many more IL 76 for one C 17. However, be gracious enough to read what I wrote about how one lift adds to the combat efficiency rather than many lifts? Please read . If it is faulty, please educate.

I have also mentioned the less number of aircraft to do the same job is more economical and efficient. Please read.

A commander personally would like his unit to be landed as a whole at the same time so that the Commander can get into action quickly and not keep waiting for his unit and equipment arriving in driblets and then piecing them and stitching them together to get into action.

The delay maybe be critical!

Check it out with C 5

IL 76 is NOT unsuitable.

C 17 is merely to augment the airlift capability depending on the combat requirement.

Where a lesser payload is required, the IL 76 would do magnificently and so why use C 17 there? If an AN 32 can do the job, why use IL 76? There has to be logic and not emotions!

If one person is to move, use a jeep and not a Caspir/ Arjun. So simple! Unless ofcourse one is totally daft! It is like the Ministers not using an armoured Ambassador and instead opting for an armoured Mercedes Benz/ BMW!

That apart, if we use C 17 to support our Siachen operations, it will reduce the number of sorties done by assorted transport aircraft and hence will bring down the cost to support that operations.

Look at the net net!

Does this purchase has anything the to do with the high mobility required by the Cold Start doctrine?

Also just think about the logistics movement required if India is forced into a war with its two friendly neighbours

You talk as though I haven't read what you wrote and is oblivious about the advantages of having a bigger aircraft. I would request that you too be gracious and read my post..You will notice what I have said is that, having this aircraft at any cost is not worth it, and I believe so.

Comparing a Dakota with IL-76 is different from comparing it with C-17. Both are huge aircrafts - One is from a reliable supplier and is cheap and other from an unreliable supplier and costly - it is as simple as that. If you are not sure whether you can use it to its maximum potential in a crisis, then why have such a thing in the first place? Added to that is low number (due to cost)-if half of them are down, your (specialist) airlift capacity from them also comes down by that much - this is the flip side of it.

Even in the case of Arihant, it is done selectively on need base. Take the case of S-300/400 air defence units? That is a weapon more urgently needed by India than the transport planes. And it is offered by none other than Russia. Still India is not inclined to buy it, and instead, decided to develop our own ..why? It is costly, and moreover, we do not want to take the risk of such a crucial thing as air/missile defence using foreign maal. However, if the same thing was offered cheap, we still would have considered buying few units as stop gap arrangement.

Here the need is not stop gap, it is going to affect the heavy lift capacity over a long period. Hence we need to be more careful in selecting the aircraft for the purpose. Conspiracy theory or not, U.S.A is not in favour of India getting strong militarily. So we need to be doubly careful, that is all.

I did read your post interesting that they maybe.

The nub of your contention, as I can fathom are three, if I have understood your post correctly:
1. C 17 is too expensive.
2. It is better to have more aircraft than one, given the costs.
3. The deal is being forced down our gullet.

I have quite categorically enunciated the advantages of having a larger aircraft that can deliver a greater payload, not only from the economics point of view, but also from the military point of view.

I was not comparing Dakota to IL 76. I was merely mentioning that the IAF graduated from Dakota to aircraft of higher payload successively till it came to the IL 76. My point was to indicate that if lower payloads met the bill, we should have stuck to the smaller aircraft which were much cheaper and as per your argument, we would have many for the cost of one IL 76.

It is Alchemists Gold to believe that Russia will be friends forever. They manner in which they are increasing the cost of Groshkov should indicate that they have graduated from the days of selling armament to India for bananas! They have to survive and they realise their national interest comes first before everything else. Geopolitics and geostrategy will dictate Russia and not the mush of the Cold War days! It is time for us to smell the coffee.

On your contention that if half of the C17 were down, then there would be problems. What is half of the IL 76 are down? At least, half of the serviceable C 17 would still deliver more than the IL 76 half or three quarter down. The C 17 carries double the payload of IL 76.

Now, let me once again reiterate the issues that I have discussed over so many posts.

Economics.
1. One aircraft delivering the same payload that many aircraft requires to deliver is obviously cheaper. Why do the low cost carriers prove to be more profit making than the higher priced airlines (Indigo vs Kingfisher)? Because the low fare ensures optimum load.
2. It costs more to have adequate staff (air crew, service and maintenance staff) for more aircraft in terms of pay and allowances.
3. These staff would require housing and other facilities And that would cost more than having less staff.
4. Russian aircraft are good, but they are fuel guzzlers. In the line of my duty, I have done a study on the logistics support of a certain area and hence I am aware of the same, though I cannot divulge the details in an open forum or even otherwise unless cleared to do so.
5. Every time an aircraft takes off or lands, there is wear and tear on the runway. More the aircraft operating, greater the cost.
6. ATC will have to have greater number of personnel since more aircraft would be operating, if there were smaller aircraft carrying the same payload that fewer C 17s would carry.
7. The greater the number of aircraft, the larger would be the number of loaders. More money in pay and allowance and accommodation and food.

There are many more issues, but let this suffice.

Combat Environment

1. The more the number of aircraft in the combat Zone where the dropping is being done or air landing is being done, the greater is the threat to the aircrafts. (In Kargil, the last helicopter taking on Tiger Hill was shot down. If one could have done the job (which it could not) then the situation would be different). However, to be correct, airlanding is done when the threat is relatively less and the risks can be taken.
2. If there is a critical requirement of equipment, supplies or troops, one aircraft can land/ air drop faster than many aircraft doing the task. For instance, if you are meeting your family at Point A and you have to reach point X quickly with your own family, would it not be easier for you if they came as one group and not in various forms of transport and at different times?
3. For paradrops, it is critical that the drop is as close to the DZ. The dispersion is the biggest bugbear for any Para Commander. If the paratroopers are dropped from the same aircraft, then the dispersion is less than their being dropped from many aircraft. It must be remembered that the paradrop is being done in enemy territory. If you have seen the film Longest Day, it would highlight the issue.
Lastly, what makes you feel that Patriot missiles are a crying need and not heavy airlift capability? I presume you are not aware of what was taking place when the Chinese were posturing along the LAC. Patriots or equivalents are for missiles that carrying nukes. What are the odds that the adversaries will use it. Now check the odds of intrusion/ incursions that may change the LC/ LAC. Which is the priority?

Checked the economics of the airlift to Siachen with a plethora of aircraft vs one with greater lift? Is the IL 76 cheaper or a huge number of AN 32 or even Mis?

It does not concern India what the US feels about not allowing India to be strong. The dictum is - Have Money, Will Buy the best! From anyone who will sell. And we have the Money!

Napoleon had said England is a country of shopkeepers, the US believes 'In Green Bucks We Trust'! Note how China has exploited this issue and we are acting coy with all moral claptrap!

In protecting our Nation, there is no question of Gandhian morality!

I would rather go by Patrick Henry - Give me Liberty or Give me Death!

That is the crux of your argument, which I for one, don't believe in. When you say "many", how many? When I say for one C-17, we can probably buy 3 or more IL-76, do you mean to say, a C-17 can carry more than 3 times the load of an IL-76? If not, then it is useful only for specialist jobs like carrying an Arjun or some such heavy stuff, which I also had agreed with.

About Gorshkov, the public doesn't know how the additional cost is distributed and for what..so it is of no use to talk about it.

Now, when you put your faith in U.S.A because Russia could equally be hostile in future, I feel like telling yo,

A Known Devil is better than an unknown Angel", anyday!

Why don't you calculate 'how many' since you know all. Why ask me?

It is not about Arjun, it is about payload! Are you aware what is payload? And it is not 'specialist'. In fact, it is mundane! Is Arjun alone the be all and end all of buying an aircraft? Siachen is bunk?

About Gorshkov, the public doesn't know how the additional cost is distributed and for what..so it is of no use to talk about it except that it is your and my money!
Now, when you put your faith in U.S.A because Russia could equally be hostile in future, I feel like telling yo,

A Known Devil is better than an unknown Angel", anyday!
I put my faith in no one.

I put my faith in the Agreement we sign which ensure uninterrupted supplies. If it is not so, then it is no go!

Rest of your post is repetition..no point talking about it again
Obviously you have no answer and weaselling out! Any rebuttal on the economic or the military issues? I sure would like to be educated. Sadly, you have not been able to comment on my 'repetition' and I dying to hear from you! What prevents you since you know all?

Lastly, with all due regards to you, I find you are a trifle deficient in the nuances of airlift, strategic and tactical! Or the environment that warrant an airlift!

Done. It doesn't agree with your arguments

>>>It is not about Arjun, it is about payload! Are you aware what is payload? And it is not 'specialist'. In fact, it is mundane!

You yourself said mundane jobs can be done by IL-76!

>>>>I put my faith in no one. I put my faith in the Agreement we sign which ensure uninterrupted supplies. If it is not so, then it is no go!

Yeah! Tarapore agreement is a good example of putting too much faith in these so called agreements with U.S.A

>>>>Obviously you have no answer and weaselling out!

I can answer, but you will get more angry onlee..what's the point?

>>>>Lastly, with all due regards to you, I find you a re a trifle deficient in the nuances of airlift, strategic and tactical!

If you had any regards towards me, you wouldn't have written the second part of the sentence. Having said that, let me tell you, don't pass judgement on people whom you don''t know.

Give me a break.

Give something substantial to answer.

I am no expert, but I know how to conduct warfare and what I need! I am not passing any judgement on people that I don't know, only on what they write!

Second part of what I wrote you comment is wrong is I still am baffled is that do you realise what is an airlift? My comments is not derogatory to your profound knowledge. It is just that I wondered if you were connected with the US airlifts!

I am not passing any comments on you. I am sure you are an expert on the issue and was trying to be educated by an expert like you!

it increasingly looks like IL76 will continue to be in demand and new airframes made. the rest of mil transports like A400M and C17 are very expensive and embraer has no offering in that segment. IL76 is the onlee game in town.

IL76 with updated avionics and PS90A engine is already a done work for Phalcon. we should have ordered such planes - get 30 for the price of 10 c17.

Sorry............
I would not be so certain of this. The IL76 wing-spar does not intrude into the cabin so you would not see it anyway- hence that by itself is no evidence of this being an AN22. Also since the AN22 is a lot wider than the IL76 I would expect to see more clearance than the narrow spaces.

Further the cabin cross section is completely wrong (compare the upper cabin cross section at the bulkhead).

IL76 cross-section

AN22 cabin
T90 on the IL76

George,

You quote a figure of 345 cm for the cabin width. However even the T72 has a width of 359 cm. so per your brochure figures even the T72 would not fit into the cabin, but it does! We have photographic evidence to prove it. Further up-thread you had mentioned the IL76 was designed to fit in the T72, but your brochure numbers prove contrary. I suspect you have taken brochure figures and extrapolated to make your case as advantageous to your POV.

Anyway getting back to topic.

Since the IL76 does carry the T72 and we have some evidence the T90 (albeit disputed) will also fit. The only advantage the C17 shows is the short landing capability.

However as we all know, landing distance is completely dependent on weight, altitude, and velocity. None of the brochures which make these claims actually specify these parameters.

Further IIRC the IL76 is supposed to have a 450 m landing ability with thrust reverser. If we are to accept C17 numbers in all fairness we should also accept IL76 numbers.

Comparing the 2 we see the landing distances as

C17 3500' = 1066m
IL76 = ~500 m

Assuming both manufacturers are using best case figures (as salesmen are wont to do) the IL76 would land in half the distance of the C17. In this case I am assuming best case of light load at sea level, and velocity of just above stall during the flare in instead of the usual 1.3 x stall velocity which is normally used for landing.

Those numbers proves nothing. We know the IL 76's required barrier arrested recovery at Leh at an altitude of 10,000 ft and carrying a T72. Unless the C17 can do 3500 ft at 10,000 ASL carrying a T90 or an Arjun, that figure of 3500' landing is just that - a best case number.

So to summarize

1. The IL76 can fit in the T90 (which is to be India's main MBT for the future)
2. The IL76 can land within 450m compared to 1066 m for the C17
3. The IL76 is at-least half or 2/3rds as cheap as the C17
4. The IL76 does not have any sanction threat or any restrictions on end-use as the C17

Those are the things we should weigh - not what is the sweet spot.

Does C-17 has loiter time over combat zone? I did not understand what is meant by that.

http://forum.globaltimes.cn/forum/showthread.php?t=7906

Look at this link for the most expensive planes in US service C-17 ranks pretty high. If the only advantge of a C-17 is that it can land at a 1800 foot strip . i dont think it is sucha huge advantage to spend 300 million a plane.

http://books.google.com/books?id=_gsAAA ... ve&f=false

This book has excerpts how the C-17's claim on landing 6400 free world airstrips is just bloated and considering the runway strength 5000 of them are unsuitable for C-17.

My online is if we need strategic lifters to carry huge loads upgraded An-124's are a much better option and Il-76's and C-130 can carry the rest. We need to spend this money on more important stuff building a good road and rail network. Procuring some decent number of Arjun Tanks and some serious punch in terms of artillery and Anti-tank weapons.

The latest version of Il-76 the Il-76MF is way cheaper than the C-17. We got three Phalcon AWACS for something like 1.2 billion in 2004 and let it be 1.6 billion in 2009 prices. For 1.6 billion now we will probably get just 6-7 plain C-17's with no dishes on top.

IL-76MF would come for around 80-100 million now. That is way cheaper than a C-17. C-17 according to various sources runs any where from 250-300 million dollars.

Jordan Bought a variant of Il-76 for 50 Million in 2008. If the C-17 is worth 300 million it should probably take off vertically or fire dozens of AMRAAMS.

You misunderstood my point in quoting the cabin widths. The cargo bays aren't perfect rectangles, there are several ways of measuring the width. The point is simply that the An-22 is wider than the Il-76. Thus the fact that the wider An-22 can hold the wider T-90 does not mean the narrower Il-76 can.

False.

Even if the Il-76 carried the T-90 (which it doesn't), it still wouldn't carry the Arjun, various helicopters, larger MRAPs, certain construction equipment and all sorts of random bulky items that need to be moved from time to time like rail coaches

But the IL76 can hold the T90 as we see in the photograph. MRAPS etc do not need to be transported halfway across the world, only within India, which is max 3 days from anywhere within India by rail. Rail coaches are moved by rail, helicopters can fly to their destination or moved by rail.

We don't need to pay 300 million per aircraft to transport MRAPS and rail coaches. Especially if the aircraft have end-use restrictions and are sanction prone.

The T90 is going to be the main MBT of India. The army in its wisdom has already ordered 600+ units with 1000+ slated for local manufacture.

Your continued assertions on the mission fulfillment capabilities of the C17 are commendable, however we don't need the C17 when the IL76 can do most of what the C17 can do, what it can't has more viable and cheaper alternatives.

By mission do you mean carrying a T-90.

As the debate rages on if IL-76 can do it or not. How many times do we move tanks over long distances by air. About 4-5 An-132 can serve this purpose and can probably even move the Arjun itself.

It will be cheaper and better option and C-130's and IL-76 can handle the rest.

Doesn't the same logic apply to every single piece of equipment in the army?

Shalav wrote:Rail coaches are moved by rail
Well if you read the article you would know they couldn't go by rail in this case. But the point is that there's always some random bulky item you need to transport. You can't necessarily tell what it is beforehand, that's what makes it random ;)
Shalav wrote:helicopters can fly to their destination or moved by rail.
Depends on how far they're going.

Several scenarios where it might not be possible to get the helicopter in location by flying.

1. Various peacekeeping operations around the globe
2. Humanitarian/disaster relief missions (where there might not be time to arrange a civil charter)
3. VVIP transportation. Indian PM visits some distant country and needs to take the chopper along.
4. You never can tell what the future will hold for India militarily. It may be straight up military action a long ways away. You don't expect it now, but as they say, prepare for the worst, hope for the best.

Maybe you're misunderstanding what I'm getting at. The C-17 isn't to replace the Il-76. The Il-76 will still be here. But for missions the Il-76 can't do, you need something else. And that something else is the C-17.

And no, there are not 'viable and cheaper alternatives' to the C-17 because there is no plane that can do what the C-17 can

It maybe fashionable to use the words strategic airlifter but that is not material.

What is material is the payload and reaching the intended area at the same time as a lot.

It is economical to fly one aircraft than many to achieve the same aim.

In combat, exposure to enemy AD guns/ missiles is increased if too many aircraft are in a restricted airspace, which will be the case if many aircraft is used to undertake a task. One must remember that fighter escorts will have to be there when airdrops/ or airlanded ops are underway. If greater the number of transport aircraft, the greater will be the number of fighter escorts. This will thus tie up the fighters from other tasks that maybe equally important.

but given the downtime of these multi engine beasts, it might perhaps be
safer to keep more airframes around to maintain some service levels.
also more planes mean more points can be resupplied.

From my notes of many years ago:

The principles of air transport ops are as follows:

Air Situation

As transport aircraft are vulnerable to enemy air action it is essential to have a favourable air situation. It is thus a must for airlift ops in most cases.


Economy in Use

Transport aircraft are the best mode for the rapid deployment of combat forces. However, they are scarce and costly to operate and therefore, must be used as efficiently as possible. Therefore, a mix of air, sea and rail should be employed where feasible.

Rate of Flow

Transporter aircraft should operate at an even rate of flow along the route. Unserviceability should be catered for in the plan and a delay factor taken into consideration and incorporated in the plan. Proper staggering must be incorporated so that there is no congestion, and the support facilities are not burdened at the departure, en route and destination airfields.

Not from my notes:

IL 76 are not being shelved. C 17 is merely an add on.

One should not forget that it might be essential to move formations from one theatre to another as in the 1971 War. Therefore, heavy airlifter are essential.

On the issue of having more aircraft to one, let me give a domestic example.

If your family is to move from place A to place B would you feel comfortable and less hassled if they were travelling in one train or coming in different trains (because you did not get the reservation on the same train as a family) reaching at different times at the destination?

A commander always feels comfortable if his command is at a place at the same time so that he can get into action for the mission immediately rather than wait to get his command together.

Ok everyone going on and on about the Il-76 should take a step back and consider the An-124 instead.

After looking into it, the takeoff/landing/rough field performance was better than I expected, especially the notional model with uprated engine.

That said, I'm still somewhat skeptical of something that big being able to be used in tactical situations. It's ground footprint (wingspan * length) is 84% greater than the C-17. It's just a really big plane and I would want some more evidence about how it actually works at small fields.

Not to mention that it isn't in production and any new buy will undoubtedly be a new model with new engines and new avionics that hasn't been fully developed yet, so there is a lot of cost and risk.

However if you really, really want an alternative to the C-17, the An-124 is a far more credible choice than the Il-76

A could read item.
Into the 4th generation

The quantum-leap advances in technology during World War II, particularly long-range guided missiles, strategic bombing and atomic weapons, shattered the traditional dependence many nations placed on geography for security.
The Second World War had shown how airborne warfare attacks directly at the interior of a nation at its critical centres, not at predictable borders or coasts, and destroys the enemy’s ability to fight back. Today’s airborne troops are specially organised, equipped and trained for delivery by airdrop or air landing into an area to seize objectives or conduct special operations against exactly these kinds of high-value targets, and thus deliver a strategic blow to the enemy.

But although airborne units today have impressive advantages in terms of speed and range over their WWII forefathers, they are limited in their mobility after landing. For subsequent operations, time-consuming regrouping, planning, and staging must follow an airborne operation. Therefore, the greatest value of airborne forces is that they provide rapid crisis reaction, strategic power projection – combined with logistically-efficient combat capabilities.

As an example, current UK doctrine for airborne operations lies in utilising air power to insert a ground force into battle via the air flank. Typically this means creating a safe “air corridor” to protect the insertion of an assault force.
This force assaults from the air, using parachute, support helicopter, or Tactical Air-Land Operation insertion. The assault force then secures a foothold on the ground in order to secure a landing zone into which the remainder of the combat power can build up using rapid air-land, and follow on air-land of tactical transports (C-130s). The airborne force may then exploit from the airhead and link up with heavier ground forces, or consolidate for conducting peace-support or humanitarian missions.

Although some might consider the days of the massed parachute drop to be over, there are a number of advantages to airdrops. First, is the matter of aircraft range: the C-130 Hercules can, without in-flight refuelling, deliver 50-70 men over ranges of 2500 miles. Compare this with the normal range of transport helicopters: the best can only manage around 400 miles without refuelling, at a speed less than half that of a C-130 and carrying half the number of troops. Second is the speed and concentration of troop delivery. Despite troops becoming slightly separated by the very action of the drop, a higher concentration of personnel is achieved on the ground than through the use of helicopter air assault. In battalion-sized operations, the advantages of airdrops are particularly pronounced.

Beyond the obvious strategic advantages of rapid deployment over long ranges; tactically, the light airborne forces are also often the best weapon in the arsenal of democracy. In peace-support, crisis reaction, or humanitarian operations – as well as in the fight against terrorists and guerrillas – cruise missiles, bombers, and heavy armoured forces are of limited value (to say the least). The real force multiplier for these types of missions is the lightly equipped, highly trained, self-reliant airborne soldier. These are soldiers who do not involve a huge logistics chain, they do not require a month to prepare for deployment, they do not need a sophisticated (and hence vulnerable) base-camp upon arrival – they are quite at home operating on foot and can carry practically all they need on their backs.
Furthermore, the investments needed to improve the mission performance of light forces are minute when compared to heavier, or more high-tech, forces. For example, small all-terrain or lightly armed vehicles useful to paratroops cost a fraction of armoured infantry-fighting vehicles, self-propelled artillery or helicopters .
AB tps
Compare the advantage that C17 would give over others.

Even the range matters in a two front war context.

The alternative to the C-17 is the An-124-100 and the current version is 150. All of these stats are based on the inferior 100 model, to understate the performance difference.
There are no other planes that are at similar pricepoints and with similar payloads.


http://www.airforce-technology.com/proj ... specs.html

Aircraft Maximum Volume Maximum Range with
Load Range a 77t Load(C17 max load)


An-124-100 120 t 1270 m3 3333 km 5925 km
Boeing C-17 77 t 592 m3 4444 km 4444 km

From this table we can see that, compared with the C-17, an An-124-100 can:

1.) 55 % greater maximum load than the C-17
2.) 115 % more of a maximum cargo-cabin volume
3.) 33 % greater range (when carrying 77t – the C-17’s maximum load)

The Russian/Ukrainian An-124 can carry 1.5 times heavier payload, cargo that is more than twice as large, and it can travel almost 1,500 km further than the C-17 with a similar load. The newest 150 model under development can carry 150 tons. It is priced at 60-100 million US dollars. If having fewer planes to deliver payload is better, and the cost is better, what can explain the decision for the American plane?

The cargo compartment of An-124 is 36 m x 6.4 m x 4.4 m, slightly larger than the main cargo compartment of C-5 Galaxy, which is 36.91 m x 5.79 m x 4.09 m. However, due to limited pressurization in the main cargo compartment (3.57 psi),[6] it seldom carries paratroopers.[7]
