But in one video I saw ada chief say, no protype for mwf, direct production variant will be produced. It will fly in 2021-22.
It's not new aircraft but only adding canards to tejas design. If airforce orders it in large then I believe it can be inducted in 5-6years.but more powerful engine needed and strict changes in agencies.
And tejas is not failed program. It's flying and defending skies.
No, what Dr Girish Deodhare had said was that Production Standard Prototypes will be built.
Basically there won't be a Technology Demonstrator or Limited Series Prototypes built, as was the case with Tejas Mk1. Production Standard Prototypes can be built because all the technologies that needed to be demonstrated and validated before going to production, such as quadruplex digital FBW FCS, composites and glass cockpit, have all been perfected on the Tejas Mk1 itself.
As far as MWF being a new aircraft is concerned, here is what it will be-
- New control surfaces (canards), modified outer geometry and better wing to body blending. The vertical tail is taller by ~0.25 meters
- the FBW FCS will be derived from the Tejas Mk1. It will be modified as per the MWF design. It has to cater to the new control surfaces (canards) that are being introduced. It will have to be modified due to the higher weights and different CG and CL that the MWF will have compared to the Tejas Mk1
- the cockpit will be new, with Large Area Display (LAD) and side-stick controller instead of the center stick on the Mk1 and Mk1A. New wider HUD will be used. HOTAS controls similar to Tejas Mk1 and Mk1A
- Updated Fuel Management System that will be derived from the Tejas Mk1
- Updated Brake Management System that will be derived from the Tejas Mk1
- New Digital Flight Control Computer (DFCC) that is also being used for the Tejas Mk1A. Far more capable, far faster.
- New Architecture for the Avionics
- On-board Oxygen Generating System (OBOGS) for basically allowing LOX cylinders to be replaced. Current Tejas Mk1 is restricted to 10 hour long sortie based on the amount of LOX carried onboard. the OBOGS is already ready.
- New airframe structure, which is obvious given the much higher payload, internal fuel, etc.
- Wing span increased by 0.3 meters. This is done by moving the wings out, not by making the wings bigger. As it is, the Tejas Mk1 has the LOWEST wing loading of almost any fighter in the world. MWF will maintain the same low wing loading thanks to the addition of canards that will also generate lift, despite wing area not being increased from the Mk1. As you might know, Low Wing Loading equates to maneuverability.
- New wing-tip pylons to carry CCM (ASRAAM class)
- New inboards, that include the wiring, piping, etc. Again, it will be starting off from the Tejas Mk1 and modified accordingly
- AESA radar that will most likely be the indigenous Uttam AESA radar, which is currently being tested on a Tejas prototype. Out of the 18 air to air, air to ground and air to sea modes that needed to be tested, 10 have been tested so far.
- new Long Range Dual Band IRST, most likely derived from the indigenous IRST that is being developed for the Su-30MKI
Earlier this week, the Defence Acquisition Council (DAC), led by India’s defence minister, also approved the indigenous design and development of a long range dual band infrared imaging search and track system (IRST) for the Su-30 MKI. At least 100 units are to be procured.

A lot of work, but still a derivative of the Tejas, since the baseline is the technologies that were developed for the Tejas Mk1.
Thank you
I am not expert but I don't believe things are simple like u say.
Upgrade can only done after producing all foc in 4years.till then no gun, no bvr, no jammer, what good is it, maybe for training only. Who thinks of making fighter without bvr and gun.
Radar with imported radome work now.
I never said it was simple. It requires a lot of work, but ADA, HAL and NAL are deeply involved in it along with other DRDO labs. The govt.'s direction is clear- the MRCA will be the last imported fighter. Indigenous fighters are the way to go and funding is made available to make that happen.
So please tell me why is it that upgrade can be done only after producing all FOC jets? And be specific.
Did you see the Tarmak video carefully? If so, did you not spot SP-1 (LA-5001) and SP-5 (LA-5005) in the hangar right next to SP-21? They were both in the hangar undergoing some sort of repair or modifications (engine was taken out of LA-5005).
Software upgrades don't require the airplane to be taken apart. I don't know how aware you of software deployment and testing, but it can be done with the airplane grounded for a couple of days, then tested and flown. And the gun and the pylon to carry the Derby BVRAAM (which was there on SP-21, now called SP-17) can be integrated by HAL easily in the hangar. It doesn't require overhaul to be done.
SPJ is coming with the Mk1A. the problem is the lack of internal space. But it will eventually find it's way back into the Mk1 too. It is a high priority item.
What is the problem with the radome being imported from Cobham? It works beautifully and allows the Tejas' Elta 2032 MMR to be used to it's full capability.
As for who thinks of making fighter without BVR and gun, check out what the Typhoon Tranche 1 and Rafale F1 were capable of. All fighters are updated and upgraded over time. if you want everything from day 1, then you'll be sitting waiting and then
And if mwf fails to produce in time, it will become same like tejas. Ada chief says in 1-2 years for flying. It must be completed in time this time. But must think of better engine then f414. N discipline agencies.
By the way, I am very disappointed after watching new video of annanthakrishna on sp21.
Some engineers and technicians talk poorly in English like me.
Even for MA student like me is difficult to read good books because most are in English.
How did this technicians and engineers pass exams.
How they read latest development and scientific articles with so poor English.
ADA Chief never said 1-2 years of flying. Don't put words in his mouth. The MWF will follow the path of the Tejas Mk1 and Mk1A - first it will target IOC with a limited set of capabilities. Only a couple of years after IOC will it get FOC, which will require thousands of test points to be tested out.
Look at the Gripen E/F program to gain in insight into how complex this process is. When did it first fly and when is the first IOC Gripen E/F going to be handed over?
As for your being disappointed over the engineers' English, I'd say just grow up!
I work in aerospace and I've worked with Serbian and Russian engineers who could barely speak a sentence of English. Italians from Alenia who spoke terrible English. Frenchmen from Dassault who won't even attempt to speak English despite knowing the words. Japanese from Mitsubishi Aerospace who needed translators. Americans who came to the airplane factory in shorts and sleeveless shirts. But they knew their work very well and I am proud to say that I've learnt from most of them.
If you make your opinions of people based on how good their English is or how smart they look, then that speaks more about you than the others.
