Why? F-16 and Gripen-E fly with F-414, don't they? Both the aircrafts are considered medium build. Tejas Mk2 just has to achieve similar nos in range, speed and payload which HAL believes would be achievable. The problem earlier was attaining those nos in a light aircraft.
It would be nice to do some basic research before you post.

The Gripen E is powered by the F414 with a max wet thrust of 98kN.
F-16s have been powered by several different versions of 2 different engines the PW F100 and the GE F110 both of which are more powerful than the F414. Late model F-16s have the F100-PW-229 (129kN). Some versions like UAE's blk 60 have the F110-GE-132 variant making 144kN.

Brochure claims aside, simple physics will tell you that the Gripen will not be able to lift the same payload as an F-16 with so much more power available. That does not stop Saab from claiming ridiculous values for the Gripen's max payload in brochures. Evaluations by the Swiss and Indian AFs brought out the truth however. The Swiss evaluation comparative report was posted here earlier to show how hollow Saab's claims are. Not surprising since they were basically hawking us vaporware during the MRCA trials considering that the definitive Gripen E prototype made its first flight only in June 2017.

Yet like clockwork, we always have someone righteously asking why ADA/HAL cannot match the Gripen's brochure claims in the Tejas Mk2.

I hope that HAL manufactures atleast 6 LCA in FY 2018-19 but 9 would be super.

I hope someone in MoD has ordered another 83 F404-GE-IN20 engine as I could only find reference of 41 engines out of which 25 are flying and I assume other 16 are already on the floor or final assembly line :eek:

IAF RFQ for 83 aircrafts - Type MK1A filled by HAL on March 13th 2018. SP 10 on assembly line,looks at least 2-3 months away from flying...

SP-10 seems to be in equipping phase which means that all the structural coupling and assembly is completed and the looming etc. are going on. Looks like half of that work is also complete. This stage on line 1 currently takes about 2 months. Therefore, I would expect SP-10 to take to the air in less than a month if all LRUs are supplied. This is exactly what label on the tea box said!

IAF issued HAL the single vender tender on Dec21, 2017

http://www.business-standard.com/articl ... 050_1.html

mk1a will differ in 4 areas from mk1

While HAL builds these 40 Tejas Mark 1 fighters, it is also working on four major upgrades that will transform the current version of the fighter into the Tejas Mark 1A, of which 83 will be built.

Of the four upgrades, the two most operationally vital involve integrating the fighter with “active electronically scanned array” (AESA) radar, in place of the Tejas Mark 1’s manually scanned Israeli Elta EL/M 2032 radar; and integrating a “self-protection jammer” (SPJ) that is carried in an external pod under the Tejas’ wing.

Two other upgrades – improving the “maintainability” of the fighter, and fitting it with external refuelling capability – are already well in hand.



---
imo it will be a formidable a2a platform with astra, derby, r73 , HMS topsight/topowl and aesa radar.

other than F-15C/Saudi/SK/Sg APG63, JSF , F22 , F-16 block60 there is no other in-service fighter with aesa radar even today.

rafale RBE2EE I dont think is on the french AF fighters , will it come in our rafales ?
Eurofighter Captor-E will remain a dream - underfunded, weak, laachar, majboor .... :D
russian irbis-E is not on anything yet

baki to aur koi nahi hai muqabla dene ke liye ....

Add the F-18E/F, IAF Jaguars, EA-18G, F-15E (AN/APG-82), Rafale, F-2, and in the next few months, the F-16V (Taiwan) plus whatever the Chinese have/claim to have fielded on the J-10. The first Typhoon AESA is fully funded for integration on the Kuwaiti aircraft. It is the higher capability radar that is currently lacking funding support, although with the recent Saudi announcement that should take care of that as well. The USMC F/A-18 C/D fleet is also getting an AESA radar although in relatively small numbers (90 aircraft) starting in 2020.

other than US, not really very mature efforts...everyone is creeping forward to see how things go and who pays for it...preferably dumb but cash rich export clients :D

hence unlike our Tejas which reached IOC 3 decades after similar a/c from the world leaders, Uttam is not starting with such a great lag

how many rafale in french AF
(a) have the rbe2 aa today ?
(b) funded to get it in future?

my prediction - they will fund a token number and call it a day, relaying on making money via sales to india (36+36), egypt etc of the sooper dooper kit. they deleted the OSF IRST for funds claiming that damocles pod would do the job and no real a2a work was needed.
#weak

big talk from 2011 saar - only around 30% of their rafale at best have the rbe2 aa maybe less

To complete 40 LCA, it will take another 4 years for HAL @ 6 to 10 per annum. For 83 LCA, I assume rate will pick upto 16 per annum ie another 5 years, though 24 per annum is preferable. For next 200 Mk2, it may be another 8 years even @ 36 per annum, so 48 per annum is required.

the production agency (GE) will need to be given confirmed orders years in advance for the GE414 to get these things flowing smoothly to us without delay when we need it.

for Uttam also, the time to train people and get the BEL line ready is NOW, not after it passes all tests....changes are unlikely to be any or very minor in HW now, it will be sw changes mostly.... subsystems which are deemed ok for tranche1 need to be given orders and outside OEMs gotten lined up and delivering stuff. stuff like power modules, cooling module , motor, mechanical frame....these wont change....most of the LRUs wont change

else there will be 2 years of "training, lead time and tooling up" delays after Uttam is IOC. also with highly programmable gear there is never a static FOC or the old 1 release every 3 yrs kind of ponderous timeline.....it can be made commerical type and releases and updates every few months to keep improving things...thats the way world is going.

we have to up our game into volume production, the old LRIP/LSP/POC/science project mode has to be abandoned wholesale and funds , huge funds poured in or we will be left holding the bag yet again, while import lobbies cite delays for more emergency purchases

good product managers and VPs always made sound calls when a product is shippable and what can be phased in later...endless tinkering in the quest for eternal perfection is the job of hobbyists and university labs not a warfighter or production agency.

its IAFs game to lose. they need to step up and aggressively manage these products in their pipeline. I believe they put astra on the fast track because the r77 does not really work, so fire was under the chair with 100s of unreliable bvr missiles and only aa10 to fall back on.

To celebrate completion of 65 years of commissioned service and 50 years since assuming my first command of an operational unit, visited the Flying Daggers for tea and crew room Gup.

The boys are all experienced pilots.

Boys come from varied backgrounds. M2K, Jaguar, MiG-29, MiG-27 are all represented. Soon there will be boys from Su-30MKI as well. The boys were all very upbeat about their present mount.

Some snippets from crew room chatter.

— the Mk1 is better than the non-upgraded Mirage 2000
— talk about difficulties with maintenance are exaggerated
— intensive operations have been tried out successfully
— lots of scope to increase its might
— if it is compared with all other fighters in the IAF for all-round ability, it will easily be within the top third of the list.[/b]

A very happy day for me.

Thank you very very much Sir for the update. JIngo khush hua.. :mrgreen: :mrgreen:

I say we stick these points in the first post of this thread. Appreciation and delight coming from Sq 45 is the best weapon against the propaganda run against Tejas and 'desi-karan' in general.

Typically POC mode is ahead of production stage, so if there is a wearable tech equivalent on the Tejas, they could take the whole sequences of action by IAF pilots and run them through the simulators, while going back on the FCS software versions used in the sims and see when the Tejas FCS was actually ready. That would be the ideal time when the feedback on the bolded part is sought.

Congratulations on your service milestones.

Awesome update.

I recall.yiur role in forming the first requirements for Tejas urf LCA.

Amazing mix of pilots forming the No. 45.

Did they say which role it excels?

How is it as an air combat plane?
Have no concerns wrt ground attack.

Trick question. A plane has a range of missions. Asking a pilot could focus on flying performance.

Just a compilation of all the information regarding $$ the current price tag for LCA MK1A is 400 crore to put it in comparison Rafale current negotiated cost is around 1670 crores. Even M-2000 upgrade was around 344 crores (2013 figures).

No we didn't.
People keep asking if the Al-31 can be fitted into the Tejas instead of F-404


In cars this is possible. Not in aircraft
