1, this hypothetical tanker has no real world basis to show it works in an operationally viable way doing simultaneous boom & P&D refuelling of 3 aircrafts at one time.
Real with many orders, not hypothetical (Airbus A330 MRTT - Wikipedia), (Boeing KC-46 Pegasus - Wikipedia).

2, is the advantages of 1 boom & 2 probe & drogue systems high enough compared of using 3 probe & drogue systems, to offset all direct, indirect & follow up costs in Indian context?

I already said IM🧅 just like a stealth jet is costlier than previous gen, pilot's life is priceless, so i would vouch for-
- mixed tanker & fighter with reduced RCS with dorsal spine receptacle,
- or a future IFRP on spine with automatic refuelling aid as it'll be done for AI-UCAVs.
Neither our latest phones, pc, tab, tv, ac, bike, car, etc are cheap, nor defence is cheap. Indian household money is draining into foreign firms who do their R&D from it.
 
Hey , i know amca design was remoured to be tweaked as compared to what shown in aero india 2025

But still dont understand why drdo(ada)/iaf cares so less about internal fuel capacity ??

I mean why develop internal bay fuel tank whn u can just design it to carry over 10 tonn of fuel.

In my opinion, amca should have over 10 tonn of fuel capacity when even j35 has over 8 tonn

-->As amca mk2(with 5th gen engine) will be coming when china will be inducting j36 with eadily over 20 tonn of fuel capacity

--> airfields near the border are venerable due to rocket artillary and drones ( atleast 500km) , and yyeah china will have unprecedented level of rocket artillary and drones , and much more during war economy with china level of industrialisation


--> hence we need aircrafts which can takeoff from central to south india and still can combat properly and utilize their weapon completely
Cause its a medium weight fighter jet? Each design choice will have it's set of compromises and nothing is stopping it from using external fuel tanks.

this hypothetical tanker has no real world basis to show it works in an operationally viable way doing simultaneous boom & P&D refuelling of 3 aircrafts at one time.
Has any tanker shown capability( in real world)of refuelling 2-3 fighter jets simultaneously using both boom & P&D method at the same time?

you have not provided any arguments that proves the benifit justifies the cost, much less in Indian context.

Don't reply rudely & see what i wrote-
A pic/vid is not available yet i guess.
When 183 KC-46A have been ordered by USAF, Israel, Japan & 85 A330 MRTT by Saudi Arab, France, Singapore, S.Korea, UAE, Spain, Cannada, Thailand, etc then in near future we might see pics/vids from their archives.
And a war time capability would take longer to be shown.
But ultimately the capability has been made & ordered.

Read again👇 its about cost to benifit ratio, not cost only.
you have not provided any arguments that proves the benifit justifies the cost,

See again what i wrote, I provided "discussion points" not "argument", -
- benefit to reduce RCS,
- the benefit to improve pilot survival, BIGGEST BENEFIT.
- the benefit of usage in AI-UCAVs,
- benefit of refuelling both old & new gen, no need of separate tanker for stealth jets.
- beneit of refuelling 3-4 times faster
> At such slow speeds the jets/engines are running in high economy envelope & fuel transfer after contact happens very quickly.
> Many times during war, when many jets line up, the jets are given small fuel 1st enough to loiter & wait, then again topped up.

> Older gen can continue with drogue-chute.
> AI-UCAV would ideally be expected to refuel itself not by remote-control, hence automatic refuelling for both systems of drogue-chute & boom have been tested long back.
> In manned jets too the more time taken by pilots can be saved by such auto-reuelling aids.
> A future manned stealth jet can have IFRP behind the cockpit on spine, with auto-reuelling.
keeping myself in place of pilots in cockpit, I would vouch for higher pilot survival chance with lower RCS & little more waiting time if needed with these dual mode tankers.

but you don't wan't to consider any point.🤷‍♂️



much less in Indian context.
- Indian context wan't to make UCAVs which will need auto-refuelling aid in case of drogue-chute, otherwise boom.
- Indian context also wan't to import GCAP, FCAS which will have huge cost when our currency value is far weaker than theirs. If they give IFRP then ok but if they implement spine receptacle then boom system.

So, basically as I said before there is no real world basis of simultaneous boom & P&D refilling taking place.
The only source of it taking place in future are your words.

benefit to reduce RCS,
How? Amca will have retractable probe, so how does receptacle help in reduce rcs compared to an retractable refulling probe?
Or are you talking about during refuelling? If yes, Really?

the benefit to improve pilot survival, BIGGEST BENEFIT.
Generally, Probe-and-drogue is generally considered safer due to greater separation between aircraft and less collision risk, whereas boom refueling is faster but riskier.

the benefit of usage in AI-UCAVs,
They can have retractable refulling probe too.

benefit of refuelling both old & new gen, no need of separate tanker for stealth jets.
You can do that with probe & drogue too.
Along with our legacy fighters newer amca will also have refuelling probe.

but you don't wan't to consider any point.🤷‍♂️
You treat your point as if its the truth, I would like to know on what basis is boom method more safer for pilot compared to probe & drogue.
Most of the source is found treat probe & drogue as the safer of the two.


Indian context wan't to make UCAVs which will need auto-refuelling aid in case of drogue-chute, otherwise boom.
Why wouldn't they need auto fuelling aid in case of a receptacle?


Indian context also wan't to import GCAP, FCAS which will have huge cost when our currency value is far weaker than theirs. If they give IFRP then ok but if they implement spine receptacle then boom system
That's a hypothetical, even in that scenerio you envision,possibility of IFRP is there.

No, it is basis, word & action of Boeing & Airbus, after product life cycle of proposing, making & testing, manufacturing, selling to 17+ nations with 183+85 orders so far. I'm merely conveying it.
But you're expecting not to vouch for the system until they release their archive pics/vids. The users/customers have seen & paid, they don't care when citizens will get to see.🤷‍♂️

Good question, you are designated as senior memeber, i thought you know this - Surface discontinuities, crevices, gaps, bumps, round surfaces, vents, etc contribute to RCS.
1777802180193.jpeg

Although different RF bands react differently, so it is diicult to optimize a jet for all bands, but efforts are being made.

1777802339115.jpeg

So IFRP will contribute to frontal & RHS RCS.
But a spine receptacle is smaller, hidden from lower hemispherical angles.

Generally, Probe-and-drogue is generally considered safer due to greater separation between aircraft and less collision risk, whereas boom refueling is faster but riskier.
That's right so far, but the makers have tested, certified & then only got so many orders from 17+ nations. Hence i mentioned 2 things -
- drogue-chute based jets will be at higher level, boom based jet will be at lower level.
- Automatic aids have been tested on both systems.

They can have retractable refulling probe too.
Certainly, but depends on UAV shape, size too. Many people take UAV loss too easily bcoz human pilot not killed. But a true fighter UCAV would not be cheap. So money will be spent/lost in some way. And still if IFRP is desired then ultimately the UCAV has to refuel by itsel, so IFRP can be put on spine.

You treat your point as if its the truth, I would like to know on what basis is boom method more safer for pilot compared to probe & drogue.
Most of the source is found treat probe & drogue as the safer of the two.
Again it is rude to say that way. My points are merely conveying & sharing what is seen on media since decades. And in technical world also difference of opions exist hence multiple companies with multiple products. Even pilots & engineers opinions also differ.🤷‍♂️
My primary point was RCS reduction, but both system have their dangers -
- boom striking the A/c, but the boom has telescopic shock absorbers, aerodynamic flaps, multi-axis hinges.
- drogue getting broken & sucked into intakes.

Why wouldn't they need auto fuelling aid in case of a receptacle?
The entire AI-UAV is an automatic robot which will need to aid itself in both systems.
As we can see in the screenshots, in boom system the auto aid is on the tanker, but in drogue system it is on the jet.

That's a hypothetical, even in that scenerio you envision,possibility of IFRP is there.
Ocourse both possibilities're there, but it is the PCM of stealth geometry design R&D which i conveyed.
"Hypothetical" means 'based on situations that have not yet happened, not on facts' BUT it doesn't mean that something yet to happen can't/won't happen. Engineering or making something new which doesn't exist so far begins by imagining then drawing then making & testing...
And after all this also, b/w people, pilots, engineers, companies & within companies too there'll be difference of opinions on cost Vs tech.;)

Whether a manned jet or UAV/UCAV, if the IFRP is put on spine with auto-refuelling then the tankers can remain of drogue type & the jets can have lower RCS. But it may look too futuristic, complex to some, unless some maker does & shows it.

I am stating that neither Boeing nor Airbus have demonstrated or shown any intention on demonstrating probe & drogue and Boom refulling simultaneously,neither boasted about having that capability.

And how do you know user/customer has seen that Boeing or Airbus has the capability of simultaneous refulling using both methods?
Who told? What's your source?


---------------------


So far its either 1 aircraft refulling at one time using boom.

Or

Or 1-3 fighters refulling at one time using P&D.

These are choices customers get, they choose either of these methods based on plethora of factors including commonality factors.


So far its only your words, that say we will see pics of simultaneous refuelling involving both methods in the future.

346820-ce501145936b9d593aecc22e5f68fe73.png
The panel on top of IFRP seems pretty flush to my eyes.
346820-ce501145936b9d593aecc22e5f68fe73.png

Same case there for f35, its hard to distinguish the panel when IFRP is retracted
which-is-the-f-35s-standard-aerial-refueling-method-and-v0-j18bybpc8gm71.jpg

So IFRP will contribute to frontal & RHS RCS.
But a spine receptacle is smaller, hidden from lower hemispherical angles.
A very shallow theory, not taking into account that you can make the IFRP flush with rest of the surface when retracted, F35 already demonstrated it.


That's right so far, but the makers have tested, certified & then only got so many orders from 17+ nations. Hence i mentioned 2 things -
- drogue-chute based jets will be at higher level, boom based jet will be at lower level.

You specifically emphasized boom being a more safer methods for pilot.

As for your hypothetical scenerio, even if we assume it is operationally viable, is the benifit worth the cost? We don't have any large bombers to refuel half way around the world.
Even our AWACS that will need refulling within Indian mainland are small EJ145 based ones already modified with an IFRP instead of a receptacle.
Our needs are quite regional, there will be few scenarios where large IAF aircrafts will need refulling, Probe&drogue being fine for those rare cases.

Its not like we have a situation where we can afford to buy niche capabilities, our tanker fleet is pretty stretched and whatever small quantity of tankers we will buy will have to be compatible with vast amount of platforms we have in service, in that case the only way we get boom system is if we pay extra to get our tankers modified for both probe&drogue and boom & also modify our future jets with a receptacle in the back for questionable benifits at best.
we also don't need to maintain operational viability with NATO members.

One of the main reason for boom to exist outside of USA is either the country operates US jets that have receptacle built in or for nato compatibility reasons.

For us none of these reasons work.

Certainly, but depends on UAV shape, size too. Many people take UAV loss too easily bcoz human pilot not killed. But a true fighter UCAV would not be cheap. So money will be spent/lost in some way. And still if IFRP is desired then ultimately the UCAV has to refuel by itsel, so IFRP can be put on spine.
So you accepted ucav are not an excuse for demanding boom refulling, as either of the two methods can be used depending on variables , good job👍

Again it is rude to say that way. My points are merely conveying & sharing what is seen on media since decades.
I would appreciate if your point conveys original content that can add value to the discussion happening instead of conveying whatever media slop you heard from outside.

My primary point was RCS reduction, but both system have their dangers -
- boom striking the A/c, but the boom has telescopic shock absorbers, aerodynamic flaps, multi-axis hinges.
- drogue getting broken & sucked into intakes.
Just like boom have all these, IFRP also have their own design points & systems, like Refueling probes are engineered with shear rivets (or shear pins) at the nozzle tip, These rivets are designed to fail—intentionally breaking the valve off—if the side or vertical loads on the probe become too high.
Position Indicators: Electronic sensors monitor exactly how far the probe has entered the drogue.
Load Protection: Systems like Eaton's Weak-Link Load Protection provide real-time data to help prevent stress overloads.
Etc.



The entire AI-UAV is an automatic robot which will need to aid itself in both systems.
So your negating your earlier point and agreeing that both systems will have their own complexities needing auto-aid, good job👍.

You shared Handley Page Victor K2's pic with 3 drouge system which i'm very much aware through documentaries. It is capable of refuelling 3 jets same time & articles, videos state it has often done that, but a pic or clip is not available to public. To recheck, I googled if it demonstrated reuelling 3 jets same time & Google AI said YES, BUT, PHOTOS DEPICT ONLY PAIR OF JETS. You could do the google search, no need to depend on others for spoon feeding. This is casual chat forum, most members are enthusiasts, very few could be journalists, historian, blogger, DoD, Ex-DoD, connected to DoD. Keep realistic expectations.

1777834087059.png

So that capability was researched, tested, made, sold to users but pic/vid not available to public.🤷‍♂️
But if u hav a pic/vid to share, that would be very nice.
Now if 3 jets could operationally refuel same time at same level, then the middle jet could refuel at lower level safely. That's obvious & military is not oblidged to show 100% capabilities of any platform to public.🤷‍♂️

Now if same querry is put up with KC-46A & A330 MRTT then also result says YES, but pics/vids not available yet.

That's another assumption, f35 has already demonstrated in real life about having an IFRP that is flush with rest of the surface when retracted.
Human eyes are compared to be equivalent of 576 megapixels camera. Latest cellphones have 200 MP cam.
But vision blurs more rapidly with distance compared to RF waves & a good RF reciever is far more stronger. We see that IFRP edges bcoz light from some source (sun) struck it & reflected back to our eyes, similarly RF waves would strike the edges & reflect back in some direction, the edges are made angled to reduce RCS return to same source. But RF waves from some other source could strike & reflect to a reciever. So if the IFRP is not there then there is no reflection. 🤷‍♂️ And F-22 demonstrated lowest RCS bcoz of less surface discontinuities, bumps, gaps, etc contributing to low RCS along with other things.

🤦‍♂️🤦‍♂️ good job for you (y) for not worried about reducing pilot risk & saving a costly UCAV by sincerely understanding stealth airframe design & optimization, but using -ve word 'excuse', twisting my statements & direct me, frame me like a scapegoat. :LOL:
Different arrangement for different platform means dynamic mixed solution, not self negation, but you wan't to spin the web of conflicting narrative & get self-entangled.
You can't ignore those variables - UCAV shape & size & if the IFRP will be put on spine.
My aim is to reduce RCS, not oppose drogue system. At 1st i opined to have boom-receptacle system, but thereafter i only shared tha auto-refuelling aids for both systems + new idea of IFRP on spine which AFAIK is subtle & neither any American X-jet has demonstrated i guess, nor Indians would hence i have to fall back & incline towards boom system.


Just like boom have all these, IFRP also have their own design points & systems, like Refueling probes are engineered with shear rivets (or shear pins) at the nozzle tip, These rivets are designed to fail—intentionally breaking the valve off—if the side or vertical loads on the probe become too high.
Position Indicators: Electronic sensors monitor exactly how far the probe has entered the drogue.
Load Protection: Systems like Eaton's Weak-Link Load Protection provide real-time data to help prevent stress overloads.
Etc.
That's very good. It increases safety of drogue system, but still the additional RCS remains compared to its absence. 🤷‍♂️

Oh, there's definitely a possibility, the argument was about the operational needs & operational benifits that will make the possibility feasible.
You have failed to provide any credible point to support its feasibility, at last leaning back to the fact that its a *possibility* .
Again -ve words, framing, narrative & accusations?🤦‍♂️Please stop personal comments & focus on your understanding & opinion only.
You asked if there's a possibility of IFRP & i agreed as per the European systems affecting FCAS Vs GCAP, that doesn't relate to my success/failure, i'm not giving university exam here or presentation to DoD.:LOL:
I gave many points which you don't wan't to consider any. You have failed to understand or accept improving pilot survival by geometric RCS reduction. But you can agree/disagree, keep your opinion, i don't have any probs. Polite replies can continue otherwise not worth.

The capability that no credible entity has so far claimed is refueling 3 fighter jets using both a boom + 2 drogues simultaneously.

Its only you which has claimed that.

I would again appreciate if you stop stretching your claims to try to make them fit.

And no, Google A.I. is not a credible source of any kind in these matters.

The method you claim has to be feasible operationally not just it being possible.
For that to happen it first need to be deemed worthy enough to try by an airforce, so far no one has explored it despite technology not being a bottleneck for it, the silence speaks for itself .

So if the IFRP is not there then there is no reflection. 🤷‍♂️ And F-22 demonstrated lowest RCS bcoz of less surface discontinuities, bumps, gaps, etc contributing to low RCS along with other things.
Gaps around the door/panels are filled with conductive seals or radar-absorbent material (RAM). The entire surface (including around the door) is coated in RAM. Tight manufacturing tolerances keep any remaining gap far smaller than the radar wavelength, which results in No significant "edge" for radar waves to scatter off in the closed state.

Typical fighter/ground radars use wavelengths of 1–10+ cm (X-band ~3 cm, S-band longer). Features much smaller than ~λ/10 (a few mm) behave very differently—they don't produce strong specular reflection or diffraction in the same way. A "flush enough" panel (sub-mm tolerance) is electromagnetically indistinguishable to radar.

Where? Quote it. My point was lower RCS improving pilot survival. But both methods have their dangers.

you made 2 seprate distnct point with no indication that they are connected to each other, its clear as day.
👇
- benefit to reduce RCS.
- the benefit to improve pilot survival, BIGGEST BENEFIT.


How many times will you ask same question is different ways & how many times would i state multiple benefits, the increased pilot survival with reduced RCS being the biggest benefit?
You treat the benifits you quoted as truth when at best those benifits are debatable.

Yet you assumed them as true and use them as basis of your arguments.


Your prime argument of reduced RCS is a debatable point, as you can make a panel that opens & closes,
flush enough for it to be indistinguishable for radar waves from X to UHF/VHF.

Your priority is to reduce cost at expense of pilot's life risk, while my priority is spend little more money to reduce RCS & increase pilot survival chances.
Your priority is to do mental gymnastics to some how fit your claims, with you treating a debatable point as truth and arguing use that assumption as base.


Rest your arguments also uses that *reduced RCS* point as base, so I won't engage with them further.


FYI
In general radar physics, a wave "ignores" or does not significantly reflect off a discontinuity that is smaller than half its wavelength, For X-band radar, which has a wavelength of approximately 3 cm, this means features smaller than roughly 1.5 cm will typically not produce a strong enough reflection to be detected as a distinct object.

Also FYI.
We are going with a retractable IFRP for our future stealth jet.


You're opinion is not just different, its factually wrong, supported by shallow misunderstandings and mental gymnastics.


If it was actually true that panels that opens&close creates enough of an edge to make a meaningful dent in stealth of a jet, than F-35 wouldn't had an novel feature like internal ladder built in too.

"claim" is another inappropriate word for a casual chat forum. We're going in circles. Military will show things as per their will. Hence your expectations of hard evidence on casual chat forum is wrong. You need to approach the makers directly to satisfy yourself. Even in technical world, every techie's technical perceptions are not equal.
But the point started with RCS reduction of AMCA with spine receptacle & boom refuelling, not capability of 3 jets refuelling same time,

You treat the benifits you quoted as truth when at best those benifits are debatable.
Yet you assumed them as true and use them as basis of your arguments.
Your prime argument of reduced RCS is a debatable point, as you can make a panel that opens & closes,
flush enough for it to be indistinguishable for radar waves from X to UHF/VHF.
Your priority is to do mental gymnastics to some how fit your claims, with you treating a debatable point as truth and arguing use that assumption as base.
Rest your arguments also uses that *reduced RCS* point as base, so I won't engage with them further.
FYI
In general radar physics, a wave "ignores" or does not significantly reflect off a discontinuity that is smaller than half its wavelength, For X-band radar, which has a wavelength of approximately 3 cm, this means features smaller than roughly 1.5 cm will typically not produce a strong enough reflection to be detected as a distinct object.
Also FYI.
We are going with a retractable IFRP for our future stealth jet.
You're opinion is not just different, its factually wrong, supported by shallow misunderstandings and mental gymnastics.
If it was actually true that panels that opens&close creates enough of an edge to make a meaningful dent in stealth of a jet, than F-35 wouldn't had an internal ladder built in too.

you made 2 seprate distnct point with no indication that they are connected to each other, its clear as day.
👇
Since beginning i'm saying that no IFRP & other sufrace discontinuities means no reflection, lower RCS hence higher pilot survival.
But you got confused b/w improving pilot survival connecting it to drogue Vs boom safety. That's your comprehension error.

"claim" is another inappropriate word for a casual chat forum. We're going in circles. Military will show things as per their will. Hence your expectations of hard evidence on casual chat forum is wrong. You need to approach the makers directly to satisfy yourself. Even in technical world, every techie's technical perceptions are not equal.
But the point started with RCS reduction of AMCA with spine receptacle & boom refuelling, not capability of 3 jets refuelling same time,

This entire reply is an poor attempt in gaslighting, after you have failed to back up most of your assumptions and claims.



Not worth engaging any further in this mental gymnastics from my side.

Relax m8, they are going for a forward looking IRST with a spherical housing. I doubt any extra panel would hurt much.

I'm relaxing with Mojito 🍹 , Thandai🥛, Cold coffee:coffee: with icecream🍦I hope others're having too, but personal comments should be avoided.
It's that 'doubt' area i try to focus on. It won't hurt us but the pilot. It wouldn't hurt MUCH but definitely hurt somewhat 🤏:LOL: as future missiles also improve.

I'm ok if people wan't Su-57, F-35, etc as their reference, i mean what anybody do about it, so i've chosen F-22 as primary reference & secondarily i mark all good stuff from other jets as well.

Stealth documentaries & articles since decades say that every element/aspect has its own contribution & round surface is worst RF reflecting geometry even after RAM, RAS application. Curved surfaces are limited to some edges, top side, etc to handle aerodynamics, heating, etc. Faceted design distributes the facets in some pattern.

Speculations on future Su-57 cover has been there.

F-35 EOTS, behind faceted cover, does the sweeping IRST function also in lower front quadrant of sphere, as seen in many videos. So an upper IRST can also have that faceted cover & TFX Kaan is also an example.

We're making that cover for lower EOTS, can be made for upper IRST as well.

A more modern design would replace gimbaled sweeping sensor behind faceted cover by DAS. The F-22 MLU will be replacing AN-AAR-56 DAS-MLD by TacIRST (Tactical IRST) doing MLD+IRST functions like in F-35.

You yourself said its confidential, so we can't say for certain if its more advanced that f35.

Great, Another person with another claim they can't back up.

You are talking crap. F35 is prone to jail brakes and reverse engineer where as F22 is tougher to reverse engineer. More over NSA has put a red flag on the encryption technology on F35 and this is why Pentagon wanted an upgrade. More over the ground network system for repair and maintenance ( Odin os) has got vulnerabilities. The F22 is free from this.

Also, at the time of its induction and during development, Northrop Grumman publically promoted the AN/APG-81 AESA radar of the F35 as the most advanced, capable radar in the world, providing *unmatched capabilities*

They may say whatever they want, it is not just the strength of radar for the stealth but signal processing and encrypted on board fiber optics data transmission network which connects the radar and sensors data flow to the mission computer which is also an important part of stealth. F22 uses the best technology and most trusted one as of now. The 80 W Dual signal processing element is so planned and cooled that any IR sensor can't detect the heat dissipation even on ground if the electronics are on for repair work. The signal processors are now being upgraded with the new AI supported microprocessors, earlier they had intel i9 processor. The cabling is smooth and untraceable, plus robust.

After the new upgrades on block F22 Block 30's with sensors like TacIRST and new firmware on encryption technology for CNI, it will beat any F35 currently flying. Kinematics, oh well they already are way superior.

Waah waah, what's your source? Any proof to back up this claim and expose my crap?

Have you ever though f22 being free for this is because its outdated compared to f35, hence f22 is getting a MLU.

And what's the source this best tech of f22 is better than f35? Please don't be that guy that say i'm the source.

As for my sources,
already showed the video of Northrop.

I won't engage further with your assumptions.


--------

I like to make an extraordinary claim, you are a retard talking crap, creating bullshits from your mind.
And unless you back up your claims with a credible source like I did, don't bother replying back, i've no Intrest in arguing with a confident retard that can't back up his claims.

Your words are worthless,
provide credible evidence that f22 is more advance than f35.
Just because it seems true to you, all makes senses in your mind on how it should be, doesn't make it true.

Your words are worthless,


However, Robert Behler, the Pentagon’s independent weapons tester, characterizes the current schedule for C2D2 as “high risk” and said the program office is struggling to stay on schedule, he said in an annual report published Jan. 30 by the Operational Test and Evaluation Office.

“The current Continuous Capability Development and Delivery (C2D2) process has not been able to keep pace with adding new increments of capability as planned,” the office’s director wrote. “Software changes, intended to introduce new capabilities or fix deficiencies, often introduced stability problems and adversely affected other functionality.


India needs a system based on F22. If US can export it to India then that will be the game changer. But they won't for the obvious reasons.
