https://twitter.com/GODOFPARADOXES/stat ... 92096?s=20 ---> Without LCA Mk2, production efforts for AMCA will suffer even more, LCA Mk2 will allow development & experience with latest production technologies bridging the gap between 4th and 5th generation production related technologies. LCA Mk2 will be the sword wielded by IAF compared to AMCA use as a spear.

3) Even if you import 500 of the latest western strike fighters, the PLAAF will simply build 5000 J-10/J-31/J-20 and you'll be left high and dry once again...something Gp Capt. Tej Prakash Srivastava doesn't understand
If the PLAAF can produce 5k pilots with sufficient skills to pilot the aircrafts during combat, you may have a point. But you forget one key thing - without man in the loop, the most advanced flying machine is nothing but a dumb brick.

It is not so easy to produce and maintain 5k pilots with sufficient skills.

It's not as difficult as you think it is.

The ability to train just 750 pilots every year and retain them over a period of 10 years will give you 7500 pilots.

An average individual can be placed in a fighter trainer cockpit with as little as 500 hours of flight time.

It's in the fighter trainer cockpit that he learns to fly and acquire skills to handle his actual combat aircraft.

Full motion networked simulators are an excellent tool for mastering the skills needed to exploit the capability of the platform.

The skills acquired in the simulators can be honest in actual flying missions.

An airforce with the ability to learn as an institution will always be testing itself during training to see what works and what doesn't and adapt accordingly.

The different air wings of PRC have demonstrated that they are eager to learn. So much so, that they were using retired western personnel to train themselves. Until not that long ago.

That ignores attrition. Flying skills are perishable and require typically 150 Flying hours every year to retain certification. And pilots transition to more administrative duties each year as they get promoted/age out. Plus there is transition between types as well in their career

It takes 1.5-2 years to train a pilot (basic, intermediate, advanced) till they can be moved to a operational squadron . Where they learn operational skills on top of type certification. And pilot candidates do wash out of Flying school at each stage.

And thus excludes defense training prior to flight training. Where it may take 3 -4 years for a NDA joinee to become a pilot https://www.financialexpress.com/busine ... f-2924620/



How long does it take a pilot to be useful or master his craft in a operational squadron is not a binary question . In one sense, it can be anywhere from 2 months to 2 years. In another, they will spend their entire career mastering their craft

So a simple 750*10 = 7500 is likely not accurate

1) The argument is not about the accuracy.

The argument is about the possibility of maintaining 5000 pilots at a high skill level. As stated in the post above mine.

2) the assumption that PLAF is not capable of learning and adapting should be discarded.

3) Even if, a pilot is transitioning to administrative position due to promotion. They are still going to maintain flight ratings.

4) in order to train 750 pilots the physical infrastructure requirements are not very high.

This curriculum can be managed with as little as

a) 375 +/- 10 % gliders.

b) mixed fleet of 375 +/- 10% low performance piston engine and high performance turbo prop aircraft fleet to manage ab-initio and intermediate training needs.

c) 375 AJT for advanced training needs.

d) whatever numbers of training version of combat jet the force has.

The major challenge is not the creation of physical infrastructure. It is the human resource. But it's not insurmountable for a determined organisation over a period of 15 to 20 years.

You need a 3 to 1 ratio in terms of pilots to planes.

With USAF having the largest budget in the world and the most advanced human training system in the world, they are still short of pilots by 2k and they have a very hard time keeping the pilots. So if USAF has a hard time, PLAAF will have a hard time too.

Nice load. Looking at the 10+ hard points gives IAF options to handle different scenarios. Does the above graphic list only those ordnance/missiles that are currently available (design/testing/production/deployment)? Because I don't see Brahmos/BrahmosNG listed in the graphic. Or, did I miss it?

IAF banking on indigenous fighter aircraft to prevent numbers going below current level
https://www.thehindu.com/news/national/ ... 5.ece/amp/
27 August 2023
The LCA-Mk2 project received sanction from the Cabinet Committee on Security (CCS) in September 2022 at a total cost of ₹9,000 crore and the first flight is expected in three years. It will have canards and be 1,350 mm longer, and can carry a payload of 6,500 kg compared to the 3,500 kg capacity of the Mk1. It will be powered by the General Electric F-414 engine, which produces 98 kN thrust compared to 84 kN thrust of the GE-404 engine powering the LCA-Mk1 and Mk1A. For Mk2, the IAF has asked HAL for certain modern technologies to be incorporated, especially related to sensor fusion and networking, officials said.

US Congress clears landmark India-US fighter engine deal
https://www.hindustantimes.com/india-ne ... 1-amp.html
31 August 2023
On June 22, the day of Prime Minister Narendra’s Modi’s historic state visit to Washington DC where he was accorded a ceremonial welcome in the White House before extensive bilateral talks and a state dinner, GE Aerospace and HAL signed a memorandum of understanding to produce F-414 jet engines in India for the under-development Light Combat Aircraft (LCA) Mk2.
....
The deal with GE Aerospace to produce 99 F-414 engines under licence is likely to be signed during the current financial year, and the first lot of engines will be made in India three years thereafter, the officials added, asking not to be named.
...
The LCA Mk-2 will form an important element of IAF’s future combat capabilities as India is planning to build around 130 such fighter jets.
...
Last year, the government gave its nod for developing the LCA Mk-2, and sanctioned ₹10,000 crore for the project. The Mk-2 fighter will be the most advanced LCA variant to be designed and developed indigenously. Apart from the more powerful GE-414 engine, it will be equipped with superior radar, better avionics and electronics, and will be capable of carrying a higher weapons payload.
....
The LCA Mk2 will have improved range, enhanced survivability, better situational awareness for pilots, network centric capabilities, and the ability to quickly switch from one role to another, the officials added.

^^^ This deal is for 99 F414-INS6 turbofans to power the Tejas Mk2 MWF. In case anyone had any doubts that Tejas Mk2 will NOT come, hopefully those doubts will have now been put to rest.

The Import Bahadurs have realized that both Mk1A and MK2 are coming. So, they have resigned to this fact and are re-aligning their attack vectors

1) Claim that Mk1A is a sub-par aircraft
2) That Mk2 will be delayed

Both these points are made in that garbage Aviation article that Sudhir Pillai gleefully tweeted

Like Chanakya, we need to destroy the enemy from the root. We fight and defeat him but let him live, re-plan, re-group and fight another day. That's our mistake

The most important constituency for import bhadurs is the IAF.

The IAF by stating that 100 additional Mk1A are going to be ordered. Have taken the wind out of the import lobby.

Come what may. MRFA if ordered, is going to be the last imported fighter for the IAF.

Lets see how the Mk1A 100 additional order plays out, how soon the ink is put on paper and what strings come with it

MRFA either needs to be buried or converted into a G2G deal for a few Rafale squadrons. That's what will truly castrate the Bahadurs and put an end to this tamasha

We can use MRFA as a negotiating stick with the French, but that stick loses its value over time, because of inflation. The sooner we close this topic, the better its for everyone to move on

No MRFA can happen without this LCA order. This order legitimizes more import. They can always point and say, look, we ordered all the Indian products we could, now we need this and that for this and this reason. It makes it easy to order another 4-5 squadrons of Rafales.

We need Swarajya types to send a signal to the import lobbyists that their run is coming to an end and they are better off switching camps to Indian defense conglomerates.
They have a growing list to chose from. And a shrinking market for imports.... the writing is on the wall for them. If 2024 goes with current dispensation, they need to think of feeding their children a lot more seriously. And all , despite the 2 steps forward, one step back. There is only one way this is headed.
Even in high value deals, with G2G option, they could end up with nothing to show.

Those with operation background in the forces will find it easy. Those who are primarily middle men, well they can make the choice.

Not only is India finally very close to finally bridging this technology gap, but the great news is that this unit so far is 30% cheaper to produce as compared to the imported Cobham radomes of the LCA Mk1.

That means we have to add 75 new planes because of wear and tear, that is assuming that each fighter gives 10000 flying hours and each pilot Flys about 100 hours every year.

Even more delays...

At India-US 2+2 ministerial dialogue on Friday, India likely to take up F404 engines supply delay
https://www.thehindubusinessline.com/ne ... 513428.ece
08 Nov 2023
It is also learnt that the two sides will assess as well the progress made in execution of the memorandum of understanding (MoU) signed between GE and HAL during Prime Minister Narendra Modi’s June visit to the US for co-development of F414 engines for Light Combat Aircraft (LCA) Tejas-Mk 2 which are supposed to replace ageing Mig-29s and Mirages squadrons of the Indian Air Force. The process is supposed to kickstart in March, next year, but the indications here are that it might be pushed further, believe defence sources.

In the mk2 thread, you were quite adamant that mk2 is essential for AMCA. But the initial proposal by ADA was to develop a semi-Stealth MCA after Tejas mk1 had been deemed failure around 2008. But here is the Statement by ADA in 2009:

“We are confident that after the LCA, it will be the MCA (medium combat aircraft) and the UCAV,” said Natarajan. The MCA will weigh about 20 tonnes — the same category as the six aircraft that the IAF is now evaluating for its $12.5 billion-plus order for 126 aircraft.

In November 2009, Rs 2,500 crore was sanctioned for the design and development of the Tejas Mk2. With regards to the MCA, how many crores was sanctioned for the design & development of prototypes? In 2009, the then ADA Chief spoke about a semi-Stealth MCA...but in that very same year, ADA shifts focus from MCA to Tejas Mk2 and is given the money for the program. Talk from ADA Chief (or any other decision maker) is cheap, but at the end of the day, money is the only metric that matters. On 31 August 2022, the CCS cleared Rs 6,500 crore for the project. So even more money is now being spent on the program. And I am still adamant that the Tejas Mk2 is necessary and essential for AMCA.

In 2009, Tejas mk1 was deemed a complete failure without Kaveri and a new turbofan was needed. Tejas mk2 was sanctioned because a new turbofan means a new plane. With mk1a, the failure has been overcome. So Tejas mk2 necessity no longer exists. Now DRDO is trying to put cart before horse. Here too, instead of IAF's choice EJ200, DRDO chose F414 because it was cheaper and quite similar to F404.

The bolded part is not factually true. I don't know where you are getting this idea from.

The first tranche of four Tejas Mk1A squadrons will replace the four Bison squadrons (all to be retired by 2025). The second tranche of five squadrons will replace the Jaguar squadrons. That will be a total of 9 Tejas Mk1A squadrons.

The Tejas Mk2 - on the other hand - will replace the three MiG-29 squadrons and the three Mirage 2000 squadrons. That is why the first planned production tranche is for 120 aircraft (six squadrons). A second tranche will also come, but for now the focus is on the prototypes and followed by the first flight.

There was a competition between the EJ200 and the GE F414 turbofan, in which the latter won. I find it surprising that the EJ200 was the IAF's choice. If you could show me your source for this claim, it would be appreciated. Thank You.

With mk1a, the failure has been overcome. So Tejas mk2 necessity no longer exists. Now DRDO is trying to put cart before horse. Here too, instead of IAF's choice EJ200, DRDO chose F414 because it was cheaper and quite similar to F404.
This is utterly untrue and is basically a desperate attempt to spread dis-information towards building a disparaging narrative of the Mk2 program.
This is not the first time this is happening, but it seems, it's kosher to do so, given the accommodative-outlook of the mods to such worthies (and their posts). :mad:

Afterall, anybody with any iota of even superficial understanding of operational constraints of putting a very high thrust class engine (say F414) into a lighter weight (say a 6T) platform, wouldn't have said so.
And there are actual hints/allusions wrt this by various ultra-closely-associated-with-the-program-from-user-perspective folks.
(I'll not spoon-feed, and people will have to figure out these on their own, if they want to - after all, what goes-to-anyones-father what these import-pasand-shills believe or want to believe, and come and crap here with their various anal-sys. It's for the mods to keep them straight, anyway)
(Hint is: search for keywords like "Muthanna"ji / "Mao"ji etc)

Anyway, the need of the so-called Kaveri replacement would have to be of the same/similar thrust class - and it was F404 all the way (the program was designed that way).
Also, anyway Kaveri was never intended for Mk1/now-1A etc from day one - it was supposed to have been inducted after an initial tranche of F404-powered platforms have been inducted etc.
I'm not aware of what that initial-tranche number was but wouldn't be surprised it would be close to 40 platforms - and the initial order (and only order) around 2009/10 was just that.
(from what we see world over e.g the "contemporary" Gripen program etc – again will not spoon-feed and people will have to figure out these on their own)

And most people don't even understand this this basic fact - a 48-49KN (wet-thrust of 81KN etc comes later, it's actually not much of an issue) TF is good enough for a combat platform of 5.0-5.5T weight class that is hoping to carry 3.5-4.0T loadouts.

Actually, it's more challenging in an hot-and-humid primary operating env, like in our country, so flat-rating etc is absolutely vital.
If people want to believe that an advertised dry-thrust of a furrin-TF (deliberately not naming, lest it hurts the import-pasand shills here in BRF), will be achieved in May-July timeframe, in a place like, say Jaisalmer etc - well beliefs can't be reasoned against, right? :roll:

A flat-rated K9/K10 wouldn't have any such issues between - their dry thrust ratings may not look as sexy in various glossy-and-technicolour brochures like those from the furinn-OEMs, but the actual users are very well aware of these facts.
(ofcourse, gora-sahibs, and their shills, would then "advice": "bhat phor the A/B is there, hain jee" etc, carefully staying silent what that does to the combat-radius etc - those minor details are for us, the kallurams, to figure out anyway - but I digress!!)

With weight creep to 6.0-6.5T (and with similar load-out expectation), 52-53KN etc would have to be required - and that this 6.0-6.5T itself would have got further escalated if K9 (overweight by ~150Kg) were to be considered.
These numbers (48/49 vs 51/53) may look quite close, but in reality they are all in the realm of approx 08-10% thrust-creep requirement from a low-BP TF - something that the world-wide the established TF OEMs, struggle with.

Also, the correlation (betw dry-thrust vs platform-weight) is actually not linear anyway.
(but let's assume for a forum discussion like here in BRF, that it is - similar to what some people here will lead us to believe that the advertised dry thrust etc will remain same/constant all through-out the life of the dginn-magic-lased-furrin TFs).

So, for an untested (requires a proven airframe first) TF, like K9, already struggling with weight-issues, there's no way to cater to this 20-25% weight creep of the platform itself.
Moreover, the 404 TF-version, that actually powers Mk1/Mk1A is INS version - one that has got an "improved" hot-section etc, which scales-up the dry-thrust to 53KN etc - a sweet-spot for a 6-6.5T platform.
And, by the same logic, a baseline 404, with 49.5KN max dry-thrust (advertised and non-flat-rated), would have been sub-optimal for Mk1/Mk1A.
Sure, for a 7.8-8.0T platform (like Mk2), aspiring to carry max 6.5T load-out, a 58-60KN dry-thrust variant is again at the sweet-spot.

There are tomes of posts on these very aspects in BRF, and anybody who claims to be an avid BRF follower, should have known all these - oh well!! :evil:


Anyway, to conclude:
But, actually, this so-called K9 failure, gave to the the-then import-pasand MoD-and-user-community-brass, the perfect opportunity to kill the indigenous TF program - which they swiftly and very successfully did.
Their excuse ofcourse was, the time-tested, "operational requirement/necessity", "doctrine", accompanied by constantly pointing to the variable-width strips on thie shoulder lapels.
What nobody cross-questioned of course was - what "doctrine", what "operational necessity", when the order is measly 40 platforms (for somebody dreaming/projecting for a 49sq (?) force-structure). :twisted:

But in our country, the shoulder-lapel-strip-widths etc, are the stuff that always gets the importance etc.

Actually, they were so afraid of the Kaveri-program to make a come-back later, and thus challenge their furrin-funded-gravy-train, they completely killed the whatever drip-feed R&D funding that was made available in 2009/10, as well.
(No dry-kaveri etc doesn't count, as it was funded much later, after an almost insistent-and-never-giving-up GTRE folks - more like a lollipop, in form of science project, to shut-up a persistent-crybaby).

Latest we are hearing is that GTRE are back at again groveling-at-the-MoD-baboon-collective-feets, to allow them some funding for a multi-axis 3D TV R&D, centred around Kaveri etc.
(refer to the Kaveri thread).

This is the point I was trying to make to Rakesh. If we had not been too deferential to the IAF brass, we would have questioned them hard on why they are not fully supporting the Kaveri program and reduce our dependence on foreign engines and force a change in their thinking and mentality. Rakesh would rather have us continue to be deferential to the IAF brass, claiming that the IAF know better than us and he would rather listen to them than to us or the decision makers.

hguptaji, IMVHO, the bigger failure was not able to force a larger MK1 order (say ~120 etc, 83 etc came much later) at the very outset - and even bigger failure was to allow the "negotiations" (between essentially two different arms of the govt) for these 83 that started about 3 years hence, to drag on for almost an decade+).
You may have also noticed, how the "imported" component/sub-system, the TF, was order in bulk in one go.
How on earth any production agency, would plan for a mass production-setup against such a measly order?

Instead, the whole-sole focus was to somehow import Rafale, at all cost - that ofcourse IMVHO, makes it neither a bad platform nor a bad choice for the role that was envisaged for it by IAF - I'm actually fully supportive of that acquisition.
Only that, the disproportionate nature of focus and the all-too-evident step-motherly treatment to an indigenous program, is what rankles the most.

From indigenous TF program perspective, I agree with you, instead of cutting-off funding, actually funding should have been increased with an aim to first baseline the K9 (in whatever form/state it was - and betw it was at a very commendable form/state even in 2009 etc), and then graduate to a 4+ gen TF program (K10).
Instead. all that happened, was some half-hearted attempt to get an imported-core from Snecma et all, which was almost destined to fail (in the negotiation stage itself) and it thus did - actually, I do commend IAF brass, for seeing thru that charade, at that time.

Who was responsible for dragging out the negotiations and limiting the purchase order to only 83? DRDO had been crying out loud that we need bigger orders to get more economy of scale and to ramp up production rates. IAF did not listen because it was afraid it would derail its Rafale acquisition program. What did we get in the end? Falling squadron numbers and inventory.

Imagine, if IAF had gone in for large orders, DRDO and HAL would have taken up the ORCA program and create a flying Rafale substitute and our Kaveri program would be so much further along in that we wouldn't be bothered or ecstatic about the GE414 engine deal back in June only to find out that GE has delayed the delivery of GE404 engines.

It is like we keep engaging in self inflicted wounds. Just bite the freaking bullet and go full steam on the Kaveri program, Tejas II, ORCA/TEDBF, and AMCA and do not look back.

3) Even if you import 500 of the latest western strike fighters, the PLAAF will simply build 5000 J-10/J-31/J-20 and you'll be left high and dry once again...something Gp Capt. Tej Prakash Srivastava doesn't understand
If the PLAAF can produce 5k pilots with sufficient skills to pilot the aircrafts during combat, you may have a point. But you forget one key thing - without man in the loop, the most advanced flying machine is nothing but a dumb brick.

It is not so easy to produce and maintain 5k pilots with sufficient skills.
