Has it yet been confirmed that the ELTA/HALBIT CockpitNG will be the present on the MK.II?



And are we looking at the Dash HMDS or the TOPSIGHT-I/TOPOWL HMDS for MK.II?

now we can do one thing forget MMRCA we can go for lca let use our own local planes

yes we can go either 50 su35 or raffale .

we have to increase our numbers if if we give priority to lca then we can give job to more Indian and in future we can update our plane

Recovery chute isn't what you put in a tight & high maneuvering (loop, split S, high G turns etc) air craft, recovery chute is best suited to light maneuvering 'Cessna' kind for which it was first developed. In case of horizontal spin aka Flat Spin only thing that can save pilots (in case of filed recovery) is ejection seat. And flat spin is some thing which is like part and parcel of 'Loop' especially when hands at 'stick & throttle' is of a rookie.
Do you have actual test results of the use of a chute on the aircraft we are talking about? No? So, no need to be so sure about it.

Besides, like you acknowledged, it's not like replacing plastic chair that is why planning should have begun well before trouble started to surface, not after situation became critical. Kind of testimony to IAF's import mania.
Is the HPT-32 imported? So, what's up with this import mania claim? Go buy Micromax and Akas tablet. If you don't have an imported phone or a tablet, then fine. If you do that makes you a hypocrite.

Buy only Indian. If you have even one foreign object in your home, like a LG TV, Samsung washing machine etc then you still are a hypocrite because all these have Indian equivalents.

No need to talk bad about the Armed forces importing if Indian equipment comes by reducing their quality standards.

Today world has already moved on to ejection seat equipped BFTs and amusingly and it took CAG report to discover, Deepaks are now outdated and unsafe apparently because of lack of ejection seat in a maneuvering piston engine powered aircraft.
Yeah! Right only CAG knows everything. How about IAF wanted to import even basic trainer but were shot down due to HAL's veto? Ever thought about that?

Secondly HAL had proposed HTT-35 long time ago in 80s. Around same time it had completed development of HTT-34 (an improved turboprop version of HTP-32). Had IAF taken initiative then, forget HTT-34 even HTT-35 would have been available as replacement quite a time ago, perhaps even in service. Needless to say, had this happened HPT-32s have had their engines frozen by now.
Only if the aircraft had conformed to requirements in the first place. No need to assume and say it did.

After rejecting HTT-35 proposal IAF was free as it always is.
India is the only country where the DPSU can veto Armed forces decisions.

And please don't talk of statistics when you cry ocean over death of pilots. Death of single pilot is as grieving as death of 400. Ask people who lost their loved ones. Are they happier because their loved one died in Deepak crash not in Mig-21s? Please!
No need to get all philosophical. 400 pilots dying is more important than 1 pilot dying, regardless of consequences and reasons. When you sign up for the armed forces it is not for a picnic.

USAF did not ground F-22s because a pilot died. They grounded the F-22s because the problems became public.

With the adoption of new doctrine, need for M-MRCA started to float far back in around 1996.
Oh! Please. The need always arises 10 years in advance before actual work is carried out. This has been the same for every armed forces for decades. The Navy pitched for a MRCA a few years ago. They will realistically get their own aircraft at the end of the decade. SFC is the same too and they may never even get it.

Given the dire need and death of Mig pilots, why is that IAF opted for this ridiculously lengthy or so called professional approach?
Vegetables right? Go buy what you want in a second?

What the IAF did, nobody else has done ever. Period.

And by the way, competitive trails approach? Did not we always know what will happen at end, how funny it is that? Let me break it.
Right. And you think if we only pitted EF and Rafale do you think 5th gen avionics would have come cheap? It was Boeing which brought in the AESA, not the others.

This will be the cheapest way to buy Rafale and this has been done many times. Did oyu know about the controversy surrounding the one of our earliest tenders involving Mirage-3s, Jaguars and Viggen. Sanjay Gandhi's interference after Jag was selected because Viggen was the supposedly superior platform. But IAF insisted they always wanted the Jag and after that Sanjay backed off. Well, same case.

Do I need tor mention J-20? Did not we always knew China was doing something on 5th gen front?
Super MKIs and PAKFA... what now?

Now they even have J-31.
Most probably Navy, not PLAAF.

Secondly, Mirage part among whole MMRCA saga is a bloody big annoyance, a bus missed. Back then Mirage-2000-5 was an excellent front line fighter with 6.5 ton weapon load. Further Dassault had offered to shift entire Mirage line to India. Quite acceptable to say, if deal had been signed by 2005, production would have begun by late 2006.
IAF wanted that. But we don't know why GoI interfered. But it happened for the good.

How forgetful here to not mention fact that sizable part of Mig-21s was supposed to be replaced by M-MRCAs according to Air Force Air Warfare doctrine which stated emphasis on equipping IAF with three different weight class of combat aircraft for meeting entire range of operational requirements starting from Massive Attack to Homeland defense and everything in between...........{And people blame ADA and LCA for the death of 400 odd mig pilots}.
Not even close. Mirage-2000s were expected to replace Mig-27s. Who the heck told you MRCA will replace Mig-21s? That is LCA's job.

When project is sanctioned in 1983 and you don't get first funding by even 1991 it's called road block.
Kaveri was well funded even before 1989. The 1991 thing was LCA's issue.

When funding is received late and the process of infrastructure building gets delayed then it's called road block.
That's why dates were pushed to 1999 induction from 1996. Instead is became 2006 with first flight in 1999, then 2009, then 2011. What about now? Money is there, infrastructure is there. Even then there is that extra 6 years of delay.

You are talking about things that happened 20 years ago. Remember that. Only technology stopped LCA's progress after funding was approved. There was no FBW until 1999 even after Dassault offered an Analog one. DRDO pushed LCA's specs up, not IAF.

Dassault had offered analog FCC and ADA could not accept it because it had compulsion as a part of TD phase/Phase-1 to prove digital FCS; a compulsion which was mandated upon it by joint of Gov. and IAF, a compulsion which was necessarily to be met to get sanction for actual project development phase called Phase-2.
Wrong. Digital FCS was ADA's decision. Every Tom, Dick and Harry who knows LCA's history knows this aspect. IAF merely laughed and rightly so.

Secondly there was no guarantee that IAF would have accepted analog FBWs as part of first production batch and not have gone on to demand digital version as must have"¦"¦"¦.
Austin's mail to me;
From what i understand from P Rajkumars write up in FORCE and his book the LCA was actually a fighter which IAF specd it to something which DRDO could develop like JF-17 types but then DRDO over speced it adding all bells and whistles that the best was available and not available having zero experience in developing those in to a smallest and lightest fighter in the world all this complication led to almost the project going on for almost 25 years.
Also, this. A very important point that everybody "conveniently" forgets.
IAF is not entirely happy with LCA but as user its still supporting the program while operationally its keeping MMRCA as hedge should it get more delayed and ofcourse its their primary job as well to protect the country.
Do you really think 30% is a small or inconsiderable figure when related to most important aspect of combat flying?
Much better than your 50% figure. So, I was correcting your mistake. All the extras not necessary.

Instead of laughing their ass if IAF had selected to get proactive, things would not have escalated to this much. As a prime user, IAF could have easily mandated imported engine, imported MMR, analog FCS and rest of other never attempted technology for first batch of LCA while stressing on concurrent development of indigenous substitutes for next batches. But what happened, ahh forget it, people used to say "who cares, damn thing won't even fly" and what not.
Good. Now you are thinking along the lines of a critic. However you forget that most of this was already mandated. Just that DRDO took it a notch further and complicated it. We will develop radar, we will develop FCS, we will develop 4th gen avionics, we will develop this, that etc. Afterall how will they justify their budget and work if everything was imported.

Firstly, LCA is not substandard equipment and rest has already been replied to.
:pfft: Ok...

No i don't. But apparently you think IAF is as holy as cow and ADA is Satan's prized demon.
No, actually I don't. It is just that IAF is criticized for the wrong things not where they need to be criticized.

Btw, Mig-21s crashes attributed to human error were primarily due to training inadequacies. This was due to the lack of an advanced trainer. Whatever HPT-32s faults, it had nothing to do with Mig-21 crashes. The absence of Hawk or equivalent was, something IAF sorely needed since the 80s but was denied for any number of reasons.

Country should have never let experience gained through HF-24 project go wasted, no matter what, work should have continued. Unfortunately after HF-24, neither Government nor IAF showed any interest in perusing expertize in the domain of at least power plant let alone in any new proposal for follow on fighter projects. Least could IAF have done was to ask DRDO and Gov for starting serious work on in the form of TD on various critical technological fronts like development of Turbofan tech, Airborne fighter class MMR, INS, futuristic airframe materials etc.
Again. Idiotic assumptions without knowing facts. IAF bought a lot of Maruts if you have forgotten. Isn't that enough? Nobody offered a better engine and hence the project died. India couldn't build one engine on it's own.

Secondly, you say "IAF can triple its strength with FGFA class fighters based on assumption that our GDP will grow past of US in sometime". Wow! Sorry for being a rude shaker but to me it's nothing but a pipe dream considering what we are seeing today and also where we will be in terms of total population and consequent rise in need by 2025-30.
Ok. Your opinion, something I don't share. Neither do many economists.

I am not going beyond 2025 to predict as how IAF will look (size wise) because a lot depends on how our economic condition will be in that time?
Even IAF cannot predict.

Like to repeat that in case of two front war IAF will need well over 1000 aircrafts for fulfilling various needs like Limited offence, Ground Support, Air defense (point, area and home defense). Towards fulfilling these, apart from other assets, IAF will need huge numbers of fighter-interceptors for blocking every possible corridor suspected of being used by enemy for inland attacks.
The battlespace isn't large enough for such a large number. We an probably fit 80-100MKIs in the NE and the same in the North. Nothing more. Attrition based warfare, we will see.

Here LCA comes handy because currently it is very cost effective BVR platform and very suitable for point air defense and area defense. LCA presently carries descent weapon suit and Radar and its RCS is very small thanks to sheer amount of composite used.
More pilots dead. Also that talk of LCA being low RCS is plain nonsense. It is a regular aircraft with a RCS like that of a truck. Been repeating the same thing all over the forum.

Furthermore, a LCA working in conjunction with AEW&C (given the fact that later has capability to provide track and lock solutions in data link mode) will be even more effective because it will be able to track enemy and even fire at it without using its own MMR which otherwise would give away its position thanks to RWR.
AWACS don't give target lock information. They only vector aircraft to targets. Only missile "blind" shots may work and those shots don't kill. They only have a tactical significance.

4 J-11s will be equal to a formation of 12 LCA Mk2s and 2 tankers. That's the math.

LCA's RCS is 3 times smaller than Mirage-2000. Rafale's RCS is 10 times smaller. F-22 is 10000 times smaller. Difference?

That's your small RCS, but to a radar, LCA is a flying truck. LCA's small size is useful in only one place, dog fights and that's only if the other aircraft does not have a 360degree IRST.

One important thing, LCA does produces smaller power but in air combat there exists term called 'Combat Thrust', 'Full Military Power' (very recently it was known through Tejas web-site that 'IN20' version of F-404 can produce 90 KN, that's 5 KN extra power for combat thrust if not any better) which is reserve power a turbofan can produce at cost of endurance (center-line drop tank can quite easily manage for reduced endurance) and engine life. So in normal case LCA's MMR and EW might not have enough power to work at brim of their potential but during combat while acting as air defence fighter LCA can muster all the required power for its electronics for a period which in no case would be more than 5-10 minutes considering the fact that LCA is bought in huge numbers and always sent against intruders at number advantage of 1.5 to 1.
Yeah, I noticed. But I believe that could be emergency thrust. But I guess it is fine, and it still makes the aircraft underpowered though. This is only counting T/W ratio and not a whole host of other reasons like inlet design, drag, unnecessary weight etc.

Furthermore BROADSWORD reported back in 2011 that PV-1 is being converted to EW prototype. Wonder what that news was referring towards?
Ok. That's cute. Do you see me believing it? No.

In future when J-20 will arrive, these interceptors can be upgraded with LO materials, reshaped nose, conformal weapon bays (wing root cavity is perfect spot for conformal weapon bay), podded weapon bays etc. to keep them capable according to changing threat scenario. Also by that time our ground based surveillance radars will also have capability to detect LO aircrafts.
That's in effect a new aircraft. Let's talk about Tejas Mk3 after Mk2 is flying shall we?

Regarding JF-17 and pakis view. Since this issue has been raised, let me clearly say that stated situation (in stand-alone and AWACS linked mode) also applies to JF-17s defending Pakistani airspace against intruding MKIs, although less effectively because of lack of descent BVRAAM (may be even Radar) and lack of composite airframe or comparatively larger RCS .
Well! Best of luck to them. But they will die.

Last but not least, be it AEW&C scenario or case related to smaller RCS or anything etcetera nothing necessarily relates to what pakis have to say regarding JF-17 intercepting MKIs. But if you think so in your brain then it's your problem. May I throw back, it's about time people grow brain and get rid of retarded thinking.
Same back to you matey. At least let's get some LCA history straight instead of making assumptions.

Btw, AWACS don't do radar locks.

Read this small passage and see if you understand. Page 69.
Flying Magazine - Google Books

If you have doubts from the above I will explain what happened.

Also, as a FYI, the MKI will be locking on to the LCA at 180km while the LCA will be locking on to the MKI at, say, 120 or 130Km. And that is only considering the MKI maneuvers himself within the LCA's radar cone, like a moron, which won't happen.

Just so you know, to reduce radar detection range by 50% you will need to reduce RCS by 15 times. Also, The MKIs new upgrade will allow LCA detection at max possible range of ~400Km(like AWACS) even if the LCA is flying low. Just so we get the math right. A single J-11/J-20 would have engaged 4 LCAs even before the LCA knows the J-11 is present. Of course, AWACS help remove that advantage a little, but with J-20 even that AWACS advantage is gone.

Current Irbis-E specs call for a LCA detection at 400Km and a lock at probably 70% of the range.

Another FYI, in a recent simulation conducted by USAF when selling the F-35 to a customer, they determined that even the F-35 stands no chance against the Su-35 if support aircraft like tankers and AWACS are taken out. So, you decide where LCA (a Mirage-2000 equivalent) stands as of today.

It is nice to know the basics before jumping to conclusions, no?

Yeah! Right only CAG knows everything. How about IAF wanted to import even basic trainer but were shot down due to HAL's veto? Ever thought about that?
The question is why cant IAF combine with HAL to produce a decent turbo prop or jet trainer ,while IAF goes hammer and tons at ADA for LCA 's 50 year old delay?


Only if the aircraft had conformed to requirements in the first place. No need to assume and say it did.



India is the only country where the DPSU can veto Armed forces decisions.

If you read the JAGUAR darin update story, You can understand how IAF bungled without even noticing it does not have decent navigational aid for terrain hugging and only discovered it after they bought and then how the local talent helped with DARIN upgrade.IAF bought jags without even knowing they dont have working terrain hugging capability that is so important for DPS,you can read it at leissure in TKS tales.


No need to get all philosophical. 400 pilots dying is more important than 1 pilot dying, regardless of consequences and reasons. When you sign up for the armed forces it is not for a picnic.
If only IAF with suitable leadership and along with HAL have marshaled the effort of indigenising the spares of 1970s MIG-21 s after the collapse of USSR not many pilots would have died. Instead cheap spares from bulgaria was imported and hastened the gory o MIg crashes.
USAF did not ground F-22s because a pilot died. They grounded the F-22s because the problems became public.

They will realistically get their own aircraft at the end of the decade. SFC is the same too and they may never even get it.



Vegetables right? Go buy what you want in a second?
When it take so many years to simply evaluate four fighters ,think how many years will it take to build a 4th gen fighter from scratch.
What the IAF did, nobody else has done ever. Period.



Right. And you think if we only pitted EF and Rafale do you think 5th gen avionics would have come cheap? It was Boeing which brought in the AESA, not the others.

]Awacs gave target locks to RAFALE's AASM in libiya ,with these lock the RAFALE pilots fired simultaneously all six AASM and other misssiles in front of them and backside of them without switching their radars. So they must be all lying as per your high standards.
4 J-11s will be equal to a formation of 12 LCA Mk2s and 2 tankers. That's the math.
You can explain this math ematical fact to the members in your following posts,I hope.
LCA's RCS is 3 times smaller than Mirage-2000. Rafale's RCS is 10 times smaller. F-22 is 10000 times smaller. Difference?

That's your small RCS, but to a radar, LCA is a flying truck. LCA's small size is useful in only one place, dog fights and that's only if the other aircraft does not have a 360degree IRST.
You can bless this forum by giving the source for your claim that LCAA has a third of Mirages RCS. And also explain the FRENCH MAGIC by which the RAFALE is said to have a RCS of 0.1 sq met while it is so bigger than LCA.Hpw was this managed in RAFALE/ and how that can't be managed In LCA mk-1 or MK-2.


Yeah, I noticed. But I believe that could be emergency thrust. But I guess it is fine, and it still makes the aircraft underpowered though. This is only counting T/W ratio and not a whole host of other reasons like inlet design, drag, unnecessary weight etc.

But in the following part of your post you are claiming that New SU radars can detect a LCA 400 miles away. Then cant AWACSS do the same detection,and relay this info to LCA. You have claimed in your previous posts that one F-22 will fire the missile and another F-22 will guide it. Then why it cannot be possible for LCA? Can one LCA fire the misslie and an AWACA or SUKHOI or EW craft with larger radars guide the missile?
Read this small passage and see if you understand. Page 69.

If you have doubts from the above I will explain what happened.

How does a single J-10 or J-11 with an RCS 4 or 5 times bigger than LCA see first and lock first?
As usual you are reeling off your own pet theories here.
Current Irbis-E specs call for a LCA detection at 400Km and a lock at probably 70% of the range.

sakthi

These are all just your figures without any comprehension regarding the term RCS. According to many experts for any airborne radar the detection range of 0.1 sq.meter target like LCA is 70 Nautical miles only. However much ASEA may improve the detection level this basic aerodynamic fact cannot be changed. While asea is good enough to detect a stealthy cruise missile within 50 km,it can never detect any target beyond it's RCs range. It may improve detection at some angularities, but no front on. A low flying LCA will have the least possible RCS among modern 4th gens in the world. Missiles covered under wings canot emit any radar reflections to a high flying awacs.
Another FYI, in a recent simulation conducted by USAF when selling the F-35 to a customer, they determined that even the F-35 stands no chance against the Su-35 if support aircraft like tankers and AWACS are taken out. So, you decide where LCA (a Mirage-2000 equivalent) stands as of today.

What happened to your repeated war cry through out this thread that 5th gen will eat all 4th gen alive.Now you are openly admitting that 5th gen need the support of AWACS and ew crafts to survive against SU-35.The J-20 will have atleast 3 times the RCs of F-35 as per the shaping and stealth technology level ,in that case our rafales and sukhois can finish them off,and LCA wont be far behind either in mk-II
It is nice to know the basics before jumping to conclusions, no?

You once said that it was sukhoi that replaced mig-21s in this thread.
Now you are saying that it is the LCA that will replace MIG-21.

In this link given by P2PRADA "there is a statement that "the awacs alerts the fighters that there is an undisclosed aircraft at 110 degrees 35 derees from our establishment". When such an information is passed the LCAs can engage them with the help of better radar carrying crafts like SUKHOI or ew crafts in their fighter group. It is not neccassary that the LCA radar should physically track the target by itself because in a point defense role mandated for LCA there will be swarms of enemy aircrafts approaching and LCA too will fly in mixed fighter groups with SUKHOI and ew fighters alonside.

SO as far as the LCA carry a long range BVR that has a range bigger than it's RCS detection range, it even has an advantage over the SUKHOI in a mixed group formation. The sukhoi or EW fighter can afford to stay behind and get a lock on the target sighted by AWACS and pass this on via datalink to LCA which will fly in front, then LCA can fire a long range BVR on the approaching target. All the technological building blocks for this to happen are already in place. According to AJAI SHUKLA's blog the LCA pv-1 is already being configured for the ew role. SO the LCA may not need a SUKHOI for that job.

You cannot dispute this.

You yourself have said in this blog that one f-22 can fire the missile and another can guide it. So it is not a rocket science for the LCa to do the same. So all arguments regarding the LCA's low powered radar can be jammed by a twin engined fighters bigger jammers wont hold water. so your argument that " putting longer range bvrs on LCA is a waste of resource "is also pointless.If that is the case what about GRIPPEN's boast that they can integerate METEOR on NG?Is that also a waste of resource?

There are other advancements in the field like ESM suits on fighters that can pinpoint the surface emission of any hostile fighter and , this ESM suit will give a passive BVR lock without even using the RADAR for that purpose.,According to Dr. CARLO KOPP of Aussie air power. This is not my pet thesis.

Also all air bourne RADARs can detect a 0.1 sq meter target only in the range of 70 nautical miles according to Dr.CARLO KOPP. SO please give us a source for your claim that 0.1 sq meter LCA can be detected at a 400 km range(with or with out BVR lock at that distance?).Then argue.

The french say that RAFALE has 0.1 sq meters clean config RCS frm the front even with canard configuration and with a size twice bigger than LCA. They say that RAFALE was built with the intention of lowest possible RCS from it's inception and it has "ONE TENTH" of MIRAGE RCS.They clearly say that all the RCS reflections were concentrated oin few salient spikes and then they were all muted with treatment like composites and RAM despite the presence of CANARDS. The EUROFIGHTER also claims the same. Some claims are even more stiffer. They say even the operation of CANARDS are designed in such a way by FCS that it wont give higher RCS reflections.

IN the links posted by KUNAL BISWAS ADA too has claimed the same that the RCS reduction is the first prerequisite for the LCA program . He even posted the PDF and lab facilities used for that purpose. The RAFALE design was finalized atleast 10 years before the LCA.

Then without canards and with same RCS treatment and RAM treatment and with half the size of RAFALE how can LCA have a third of mirages RCs and RAFALE can have a tenth of mirage's RCs according to french?Please post relevant links in this regard. Don't say I heard it on a FORUM.

In forums all over the world

the LCA still cant go past mach 1.4,
it's AOA is limited to 17 degrees and it will never go supersonic in low altitudes.
It will never have asea as DRDO will refuse to put the asea developed for AMCA in LCA.
It will never have a higher power engine that AMCA will eventually have,
The CEILMAC report by S.K.JEBAKUMAR CAN NEVER BE IMPLEMENTED ON TEJAS.And tejas will be the draggiest airplane in the world.
It can also not fire a long range BVR as it can never have a support of EW crafts, but all other fighters in the world can have them.
And a higher RCS, higher empty weight,lower TWR ,higher wing loading fighter like J_10 or J-11 can always see first and lock first and shoot it's BVRs first and defeat an LCA ,because the J-10s and J-11s were made by the GLORIOUS DRAGON builders themselves.(if the pakis are begging around the world for radars and avionics for their JF-17 will show the level of sensor fusion on board the J-10)


And despite being in lower size and with RAM treatment and RCS reduction techniques it will always have an RCS 3 time larger than the other planes.
And none of the above is true as you yourself may know it.Most of this venom is being spewed based on hate psychosis and pervert jingoism.

Just so you know, to reduce radar detection range by 50% you will need to reduce RCS by 15 times. Also, The MKIs new upgrade will allow LCA detection at max possible range of ~400Km(like AWACS) even if the LCA is flying low. Just so we get the math right. A single J-11/J-20 would have engaged 4 LCAs even before the LCA knows the J-11 is present. Of course, AWACS help remove that advantage a little, but with J-20 even that AWACS advantage is gone.
These are all just your figures without any comprehension regarding the term RCS. According to many experts for any airborne radar the detection range of 0.1 sq.meter target like LCA is 70 Nautical miles only. However much ASEA may improve the detection level this basic aerodynamic fact cannot be changed. While asea is good enough to detect a stealthy cruise missile within 50 km,it can never detect any target beyond it's RCs range. It may improve detection at some angularities, but no front on. A low flying LCA will have the least possible RCS among modern 4th gens in the world. Missiles covered under wings canot emit any radar reflections to a high flying awacs.

p2prada says in page 220 in the later part of his post no-3289
Another FYI, in a recent simulation conducted by USAF when selling the F-35 to a customer, they determined that even the F-35 stands no chance against the Su-35 if support aircraft like tankers and AWACS are taken out. So, you decide where LCA (a Mirage-2000 equivalent) stands as of today.
If F-35 stands no chance against SU-35 group if support aircraft like tankers and awacs are taken out ,what are the chances of J-20 against the upgraded super sukhoi goup,if the same awacs and tankers are taken out?.LCA mk-II will be grippen NG equivalent not mirage equivalent. And in a saturated ew environment from where it will do it's point defence duties it can shoot down any J-20 with the support of ew crafts and in merge with superior numbers .J-20 will have twice the RCS of F-35 at the least judging from it's canards and tail fins and it's larger size.

It uses the discarded canard model of once considered F-35 design. As on date J-20 still has no latest jet engines and no aesa on board. By the time J-20 iron's out all of them say by 2020. Any upgraded mk-1 pilot will see the J-20 like a football in his avionics via datalink,as by then L band radars with wavelengths from 6 inches to 2 feet will give a fair indication of J-20's position. not to speak of VHF frequency that are already deployed on the Russian SAM radars.
Once their rough position is known stealth UCAVS will further assist in their pin point detection. SO it doesnt matter from which pylon a BVR missile is released, whether it is from super sukhoi or LCA or anyother.

1.Meanwhile the J-20 must get close to LCA or any other 4th gen fighter with in a range of 30 km for any fair chances of hitting. As all the advertised ranges for long range BVRs like 120 km or 200 km is only at higher altitudes and for targets that head straight on.

2.In lower altitudes and for evasive action taking aircraft the effective range for a 120+km BVR is more or less 20 km or so,supersonic release or subsonic release.

3.Even in this scenario if the J-20 's BVR missile's tracking radar is jammed by the targeted LCA's group jamming aircraft the probability of hit reduces further.

4.If you consider the modern passive defences like ESM suit on LCA or any other 4 th gen fighter that can obtain a lock on the J-20's- BVR's tracking and lock giving craft , a reposte BVR will be fired from the targeted LCA ,on the J-20 BVR's tracking craft resulting in that craft breaking lock and taking evasive action.

5.After all this there is another snippet called monopulse DFR(digital frequency reading) modern jammers that will be part of any upgraded LCA or any other 4th gen that can easily spoof the J-20 BVR missile's active seekers and L band jammers that can jam any LIKN 16 emitters in the vicinity that give midcourse update to J-20's BVR.

These are not my assumptions real scenarios any one can google and find,

SO after considering all the above 5 points for people to write that j-20 will eat LCA alive is just a wet dream detatched from the modern reality where the GLORIFIED 5th gens still rely on asea radars and old BVR techniques to score much vaunted kills on LCAs.

According to Dr. KARLO COPP and RAND study and many other genuine sources the actual probability of BVR kills will be only 10 % and that too not in modern EW environment. In modern ew environment this bluff of reliance on BVRs will be called as ew capability fully mature in 2020.

That's why BOEING chief says that it will take atleast a decade to decide what will go into 6th gen fighters and US has capped F-22s to 186 units. That's why the F-35 is being offered to INDIA. If it is so cutting edge there would not be such easy offering.

So modern combat is not about flying fast and firing your BVRs at their max advertised range and flying back. The J-20 may not have more than 6 or 8 long range BVrs. Their effective role is at best against lonely targets at sea that does not enjoy the same protection that important land based targets like airbases and command centers and missile sites that are protected by EW capable fighter aircraft groups along with awacs and ground RDARS AND STEALTH ucaVS.

SO THIS SCARE MONGERING THAT j-20 WILL EAT ALL POINT DEFENSE ROLES lca tejas SHOULD STOP.

So decent 4th gens like LCAs in huge numbers will be an asset to IAF ,not a liability.

post no 1064 page -71 by P2 PRADA,
That's the problem. See even I can make a wish list and say let's do it. For one, we don't even have the proven capability to manufacture such a large number of fighters. Secondly, Kaveri is 5 years away from any kind of tests. Thirdly, the MRCA is much more important to us than the FGFA program. Yes. That's right. The MRCA is way more important to us than the FGFA. The FGFA is a paper plane, nothing on it is reliable. The MRCA fighters are all flying right now and are all awesome killers, including Gripen. And we need them even more so. The LCA is just a filler until the AMCA comes in to the picture.

There are times we have to get out of the rabbit hole and look at things objectively. For some reason not many people do that.
So if grippen is so cutting edge why is LCA mk-II which will have the same engine , and TWR is not so.

If CEILMAC suggestions are carried out as nemtioned in the paper itself that they are being carried out

1. nose cone is extended, with provision for IRST and ASEA radar
2. higher fuel load is provided with lengthening of the fuselage,
3 weight reductions with more composite replacements for engine mountings and pylons and re engineering display mounts,
4. addition of LEVCONs to improve low speed handling and improvement of AOA as illustrated by RAHUL singh

it will be as good a fighter as any other or grippen. It's lower wing loading suits the high himalayan airspace well.

it also has the upgrade option of light weight high thrust engine and all the latest missiles for the future AMCA.
The 40 mk-Is too can be upgraded with most of above futures and there will be no issues as nose cone extension along with ASEA and IRST will pose no insurmountable problems.Fuselage extension will be more complex I suppose.
engine upgrades wont be that problematic.
post no -1062 P2PRADA says,
I will agree with the older Migs. But the Bisons are more 4th gen than the Mk1. Not to mention the older Mig-21s are actually being replaced by MKIs and later MRCA in the future.
Really? can they have all of the above updates of LCA mk-I and match the grippen NG? What is the wing loading of BISON? TWR of BISON? Most important of all how many BISONS will remain flyng without falling from the skies after 10 years? ANy chance of it getting ASEA RADAR upgrades? What is the RADOM dia of BISON?

i told him that he can become very good lawyer.
I will take that as a compliment. But the message was lost when a simpleton interpreted it.

When I said MKI is replacing Mig-21s, this is actually happening in "real life."

LCA replacing Mig-21s was the "plan" and for this "plan" to work LCA needs to be ready first. So, we know for sure things did not go according to the "plan."

MRCA was mooted to replace Mig-27s. Simple as that. My reply to Rahul was in relation to what the LCA and MRCA were supposed to do, not what the MKI was supposed to do.

MKI was meant to add capability while LCA's replaced Mig-21s. But this did not happen and instead MKIs directly replaced Mig-21s.

Anyway, I have no idea what he has been posting except for what you quoted because he is on my ignore list. But I know how any of my replies to him will go. I will end up using a lot of words like "nonsense" and a lot of facepalm smileys. So, can we avoid quoting people who don't really know anything and don't even understand simple statements. It is an utter waste of time.

Anybody reading his posts, I would say best of luck in trying to figure out what he "makes up" when comparing with actual facts.



Rant on/
Respected Mods,
The thread is being derailed by one poster who refuses to give proof for the claims he is making. None, zilch, Nada and shall not back down from making disingenuous posts. This is highly infuriating to posters who actually do. Please take notice before other posters quit posting in this thread and it gets filled with pages after pages of unsubstantiated claims, and nationalistic tripe.

Regards,
Twinblade.

Like many aircraft designed as interceptors, the MiG-21 had a short range. This was not helped by a design defect where the center of gravity shifted rearwards once two-thirds of the fuel had been used[citation needed]. This had the effect of making the plane uncontrollable, resulting in an endurance of only 45 minutes in clean condition. The issue of the short endurance and low fuel capacity of the MiG-21F, PF, PFM, S/SM and M/MF variants—though each had a somewhat greater fuel capacity than its predecessor—led to the development of the MT and SMT variants. These had a range increase of 250 km (155 mi) compared to the MiG-21SM, but at the cost of worsening all other performance figures (such as a lower service ceiling and slower time to altitude).

This is the 4th gen fighter that P2PRADA is repeatedly tomtoming as 4th gen and superior to LCA-mk1.
The following is it's lousy specs that is being seen as better than LCA.

General characteristics
Crew: 1
Length: 15.76[61] m (51 ft 8.47 in)
Wingspan: 7.154 m (23 ft 5.66 in)
Height: 4.1 m (13 ft 5.41 in)
Wing area: 23.0 m2 (247.3 ft2)
Empty weight: 4,871 kg (10,738 lb)
Gross weight: 7,100 kg (15,650 lb)
Powerplant: 1 × Tumansky R11F-300, 37.27 kN (8,380 lbf) thrust dry, 56.27 kN (12,650 lbf) with afterburner each

I would expect the same airwarfare genius who has posted that MIG-21 BISOns are 4th gen and superior to LCA mk-1 to do some explaining.And can as well explain the reason for their logic.

Are they can cry "MOD" as usual. If some feels ashamed to read their own posts in the forum,I am not responsible for that.

Sukhoi -30 MKK is an additional capability ,which is more of a strike fighter and belongs to near 30 ton weight class.MIG-21 bisons are 5 ton weighing 70s bird whose design features a "design defect where the center of gravity shifted rearwards once two-thirds of the fuel had been used. This had the effect of making the plane uncontrollable, resulting in an endurance of only 45 minutes in clean condition. The issue of the short endurance and low fuel capacity of the MiG-21F, PF, PFM, S/SM and M/MF variants" .

So people can write whatever they wish,but please don't say LCA is more inferior than MIg-21 and LCA cannot do the role of JAGUARS which have a thrust to weight ratio of 0.61 and 2 ton load with next to nothing air to air capacity.JAGUAR started it's life as a trainer aircraft and and modified into bomber with dubious . It will only expose their stupidity, nothing else.

The delay in LCA is due to the dogmatic disbelief shown by IAF . From 1983 to 1989 IAF vehemently opposed the idea of LCA.
Many years after the LCA program was started AIR MARSHAL krishnamoorthy wrote a letter to PM expressing serious doubts over the feasibility of the project . Then KALAM intervened.That's when the program was curtailed to two technology demonstrators at first and prototypes later. That was the reason for delays in flight testing. Funding was released only in 1993 for the first two TDs. The first plane flew in 2001.

The DARIN Story � TKS' Tales

It was felt that any tactical attack aircraft that were to survive in that environment would have to fly very low, below the radar net and very fast. In those heights and speeds, the navigation and weapon aiming tasks for the aircraft had to be done electronically. Normal human response was found to be just too slow.The jaguar was accepted as a tactical fighter by the British Royal Air Force and the French Air Force in the middle seventies.

The integrated Nav-Attack system fitted to JAGUAR aircraft was the Marconi NAVWASS based on a floating gyro platform. A lot was expected from it. Unfortunately, its performance on the field fell below the expected level. It was not accurate enough and it was very hard to maintain. When we became interested in the Jaguar as our potential DPSA, the performance of the NAVWASS was our main discouragement.


Gradually, it had become clear to the vendors that though we were impressed by the Jaguar, we were not so impressed by the NAVWASS. BAe's sales pitch therefore got modified and an impression was generated that if we wanted an upgraded inertial system incorporated into the Jaguar, it could and would be done easily

Ferranti was, at that time, developing an inertial system based on their version of the dry gyro. Their platform named DINS1084 was on the Tornado. Our interest in NAVWASS upgrade gave them a lot of encouragement.

The Ferranti / Smiths Instruments team came down to Bangalore. Initially, they offered only four sorties to ASTE. Naturally ASTE rejected this offer and asked for 25 sorties at a minimum. This was agreed to and they installed their system on a MiG21. The tests threw up a lot of bugs and Ferranti was obliged to ask for repeated extensions. Ultimately about 55 sorties were flown. The system performed only in the navigation mode. Some of the technical officers were impressed by the ease of installation and maintenance. Tactically it was a cleaver move by Ferranti. Impressing the ASTE was a good method of impressing the decision makers at the Air HQ responsible for new acquisitions, even though no weapon integration was tested or attempted.

It is possible that in spite of demonstrating a workable model to the IAF on a MiG21, Ferranti was not fully ready to offer a concrete proposal for a Jaguar update. It is possible that it was in the business interest of BAe to sell their product in an "as is" state and then get the GOI to retrospectively modify all the aircraft as well as pay for the development of the system

(It must be remembered that India was at that time considered to be a backward third world country easily fooled by glittering toys!).
The Jaguar contract was signed a few days after I took up my new appointment as the PM-JPMO.

A special mention in the contract recorded that the NAVWASS was to be ultimately replaced by a new system to be chosen by the GOI and that BAe would assist GOI in selecting the system for the IAF, would integrate the chosen system into the Jaguar for an unspecified sum of money and would carryout all necessary modification for manufacture of the modified system in HAL..

As soon as I was able to officially confirm the chosen structure of the proposed INAS, I wrote a letter to BAe informing them of our choice and inviting them to begin the process of integration of the system on the Jaguar. There was an ominous silence from the BAe for a few days, and then a bombshell landed on my desk. BAe said that they were supposed to have been involved in the process of selection of a replacement for the NAVWASS but we had kept them away from the process. As such they cannot take on the responsibility of integrating the chosen system with any guarantee. They would have to carry out a feasibility study to check out the system. That would need about six months of time and it would cost us about 125 Crores of Rupees. If at the end of this commitment they found the system good enough then they would incorporate the design changes for manufacture! I had no budget for such expenditure. More importantly, I was not in a position of opening a Pandora's Box where by I would lose complete budgetary control over the project. It was just not acceptable. I spoke to the local BAe rep but he was evasive in his reply. He suggested that I'd better raise the matter directly with BAe at an official level.
this was how IAF was fooled into buying a JAGUAR whose navigational system NAVWASS was below par with the false promise of rectifying it later for an "UNDISCLOSED AMOUNT". The IAF realized only later they were fooled and did it themselves with local talent in the programme called "DARIN" upgrade.

But here some members are repeatedly fooling forum members with posts like JAGUAR has become potent with "DARIN" upgrade.Actually without the DARIN jaguar was not suitable for the job it was originaly envisaged.DARIN is not an UPGRADE actually. It was the rectification of defects in a plane that was sold with below par NAVWASS navigational and bombing aid. Then IAF did the DARIN changes in 25 crore budjet. But the BAE asked 125 Crores of Rupees to carry out a feasibility study to check out the system in t six months of time .

The LCA in it's MK-II version can carry strike payload of the jaguar and air to air missiles of MIG-21 bisons and excell both of them in their own roles at the same time. It can strike better than jaguar and do air to air better than MIg, and it will exceed Mirages agility in both the roles. I am comparing it with mirages to LCA because it is an insult to compare the LCA's agility with MIGs ang JAGURS.

LCA-mk-1 without upgrade can deliver close to 80percentage of the LCA MK_II. And if better engine from AMCA program or GTRE-SNECMA program is given and CEILMAC suggestions done in a MLU will do close 90 percentage of LCA MK-II's performance.

So fools comparing LCA to JAGUAR which started life as advanced trainer and later dumped on IAF with fraudulant navigational aid and MIG-21s that have been faultily designed with, "where the center of gravity shifted rearwards once two-thirds of the fuel had been used" should keep shut up.

You will end up using a lot of words like "nonsense" and a lot of facepalm smileys for my replies because that's the seriousness with which you approach the forum.No stomach for burning facts perhaps.

You wont call me a simpleton anymore I guess, If you have any sense of accountability please reply to this post are keep shut up.

P2PRADA says
From what i understand from P Rajkumars write up in FORCE and his book the LCA was actually a fighter which IAF specd it to something which DRDO could develop like JF-17 types but then DRDO over speced it adding all bells and whistles that the best was available and not available having zero experience in developing those in to a smallest and lightest fighter in the world all this complication led to almost the project going on for almost 25 years.
This is what the dominant view of IAF always was.They dont understand that it will take 20 years to develop any fighter cun engine project. The US is struggling with F-35 despite the experience of F-15,F-16,F-14 tomcats,F-22. SAme way EADS,BAe and germans spent 30 years for EUROFIGHTER. It is still not optimized for ground bombing. Same with french who spent 17 years for the RAFAle's new engines despite previous MIrage-2000 expertise. The same for the development timeframe for RAFALE. It's been in the works for 20 years. Only now the first RAFALE fighter with ASEA is getting ready for trials.

If ADA heeded the advice of IAF and once again became the welding,cutting workers and screw driver mechanics for the IAF and HAL combine they could have put something in the air with FOC around 2000 (since from 1993 with first funding release for two TDs it will take atleast 15 years for any new first programe whatever the technology level may be).
O.K, then from 2000 to 2010 a hundred of these no "BELLS AND WHISTLES" glorified obsolete MIG-21 enhancements( with no composites, no FCs, no cranked delta ,no full glass cockpit,no 4 ton load, no exceeding mirage in capability, no tail less delta) would have flooded the IAF by now.They will have a service life of about 30 years at the least.Surely MOD wont allow IAF to junk them before, because they were built to the satisfaction of IAF ,ofcourse. it would have been a disaster for IAF.

So are these the fighters that IAF will deploy against J-20, J-10, J-11 and sukhoi clones of china? These MIG-21 enhancements will be worse than the JF-17s of PAF.IAF and ADA will be reduced to being laughing stocks of the world. I havent included the PAf's F-16 here because it will be definitely inferior to them. Then PAK jingos will be drooling all over the net regaling themselves with donkey stories about These MIG-21 enhancements.

And if ADA wants to surpass the mirage level then a new progarm for an LCA like fighter has to be started on 2000 and the LCA would have attained FOC at 2020. Who will build the AMCA then? when will it fly? You are only as big as your dreams and goals.As a research organization ADA did what was right for the country. If IAF views were upheld by people like KALAM ,the country will be saddled with obsolete MIG-21 enhancements for another 30 years.The down side is the IAF has to wait for 10 years with MIGs. But the crashes were not ADA's faults. If IAF initiated program with HAL for reliable spares and maintanence it would not have happened.

The main impetuous that resulted in the funding of LCA was the demise of the soviet union in 1990s. Then IAF and MOD realized the unreliable supply of spares from USSR and then started prodding ADA. But ADA cant do anything faster because from 1980 to 1993 nothing serious was done on LCA.with meagre funding and constant criticism from IAF ,MOD didn't release more than 500 crore before 1993. Most of the money would have been spent on setting up infrastructure. ADA is only left with design drawings and some project definition. Even in 1993 funding came only for 2 prototypes because of the IAF criticism that the program is over ambitious and its steadfast refusal to set aside anything from it's own funds for LCA.

This two TDS and further prototypes only after the success of TDs has sowed the delay of the program. If straight away more prototypes are allowed testing and redesigning would have been faster and as there will be more test flights possible with more number of crafts. ANd ADA too had to be very conservative like keeping the fully working model of a tejas on the tarmak for 1 full year doing and redoing tests .Because if that 1 TD is lost the program would have been finished.

This is the reason for all the delays and recriminations between IAF and ADA. ADA believed it can do it. and did it. IAF dogmatically disbelieved ADA and put blocks in it's path and now paying the price with 10 year delay.

BY KEEPING ME IN YOUR IGNORE LIST P2PRADA YOU ARE IGNORING THE ABOVE FACTS ALSO.

Just so you know, to reduce radar detection range by 50% you will need to reduce RCS by 15 times. Also, The MKIs new upgrade will allow LCA detection at max possible range of ~400Km(like AWACS) even if the LCA is flying low. Just so we get the math right. A single J-11/J-20 would have engaged 4 LCAs even before the LCA knows the J-11 is present. Of course, AWACS help remove that advantage a little, but with J-20 even that AWACS advantage is gone.

The following paragraph is from
Radar Cross Section (RCS)

The impact of lowered observability can be dramatic because it reduces the maximum detection range from missile defenses, resulting in minimal time for intercept. The US airborne warning and control system (AWACS) radar system was designed to detect aircraft with an RCS of 7 m2 at a range of at least 370 km and typical nonstealthy cruise missiles at a range of at least 227 km; stealthy cruise missiles, however, could approach air defenses to within 108 km before being detected. If such missiles traveled at a speed of 805 km per hour (500 miles per hour), air defenses would have only eight minutes to engage and destroy the stealthy missile and 17 minutes for the nonstealthy missile. Furthermore, a low-observable LACM can be difficult to engage and destroy, even if detected. Cruise missiles with an RCS of 0.1 m2 or smaller are difficult for surface-to-air missile (SAM) fire-control radars to track. Consequently, even if a SAM battery detects the missile, it may not acquire a sufficient lock on the target to complete the intercept.

Then where is the source for P2PRADA's claim

The MKIs new upgrade will allow LCA detection at max possible range of ~400Km(like AWACS) even if the LCA is flying low. Just so we get the math right.
If authentic source is quoted members can be enlightened in this regard.

If we google it clearly says that SUKHOI's new radar has 400 km detection range. The words for targets upto 0.1 sq meter is never mentioned.
this is the following passage from wikipedia. So there is no basis for a claim that 0.1 sq met target will be detected at 400 km.

The forward-facing NIIP N011M Bars (Panther) is a powerful integrated passive electronically scanned array radar. The N011M is a digital multi-mode dual frequency band radar.[47] The N011M can function in air-to-air and air-to-land/sea mode simultaneously while being tied into a high-precision laser-inertial or GPS navigation system. It is equipped with a modern digital weapons control system as well as anti-jamming features. N011M has a 400 km search range and a maximum 200 km tracking range, and 60 km in the rear hemisphere.[48] The radar can track 15 air targets and engage 4 simultaneously.[48] These targets can even include cruise missiles and motionless helicopters. The Su-30MKI can function as a mini-AWACS as a director or command post for other aircraft. The target co-ordinates can be transferred automatically to at least four other aircraft. The radar can detect ground targets such as tanks at 40–50 km.[48] The Bars radar will be replaced by Zhuk-AESA in the last batch of 40 aircraft
FROM---------http://www.ausairpower.net/APA-2009-06.html

Tikhomirov NIIP in Moscow are developing an L-band AESA radar system intended for embedding in the leading edges of fighter wings. A demonstrator of the L-band AESA subsystem was publicly displayed at MAKS2009.
The following are it's detection range for 1 sq meter targets. At best it can detect a 1 sq meter RCS target at 73 km. Then how can it detect an 0.1 aq meter target like LCA at 400 km?

Mate I believe that We will NOT see FORTY LCA mk1 in IAF

LCA MK1 is just a completely necessary learning experience for making a better LCA mk2

All the problems that ADA has faced in LCA mk 1 will help them in making a much better LCA mk2

LCA mk1 also costs 40 million dollars And if it is less than useful for IAF then why to make it at all

And LCA mk 1 has already been badly delayed With FOC for LCA mk1 coming in 2015

By 2015 LCA mk 2 will be ready even if it is WITHOUT AESA but GE 414 will give it the much needed TWR
and speed

AESA can come later in LCA mk2

The Most important thing is the GE 414

Orders are already placed for 40 MK-Is. They are much more effective than migs and jags. They can be upgraded close to mk-II level with nose cone extensions ,fuselage extension and asea radar.

If you see any fighter program this is the norm.

We inducted sukhois 10 years before it's actual weaponisation. Pilots train and develop tactics on it. Then they were sent back to Russia for weaponisation later. Also in tranche 3 version all TYPHOONS will have ground bombing capability not now.

The first rafale with asea radar is just about to be tested.
The grippen NG that participated in MMRCA is just a single prototype(with far more extensive changes needed than MK-I) , it's first developmental flight sheduled for 2013!!!!!!!!!!!
People look at the future when inducting the fighter not it's IOC, FOC specs..
Mk-1 is the tested plat form ,that's all we can upgrade it on the go with mk-II.
K firs and mirages in the past were upgraded with longer nosecone housing bigger radars and longer fuselage extensions in their MLU.

That is the practice world over,Mate.
