Looking really good! Great ergonomics added with a clear line of sight out of the glass cockpit. And the clean look from the simplification of digitization is quite evident.

What a beauty!

It really is indeed. That's such a great angle as well as the one below for the twin seater is superb.



I know there is criticism over how long this project took, but reflecting on that and realizing the final outcome makes it inconsequential and moot. Being that it's somewhat of a modular platform where upgrades can systematically be introduced as needed makes the development timeline even less important as it makes the aircraft even more versatile. The effort put into its development is admirable considering all the challenges and the final product.

So I'm curious as to why you have a preference for the ASRAAM vs R-73E? Wouldn't you rather have an infrared heat-seeking guidance system than radar homing, especially for 30km-40km short-range distances and especially at much closer dogfighting distances where you'd be firing off-boresight with possible HMCS? I'm just curious where your thought process was on that, or maybe it's just a manufacturer reason being that the IAF is moving more towards MBDA products even with its indigenous stuff and possibly shying away from Russian equipment?

RAM coated missiles is a great idea and wonder how effective it really is.

The fit and finish looks top notch. HAL has come a long way indeed.
Just waiting for the first delivery of MK IA, with a hope that it is not postponed again.

Are they still planning on the naval version? Last I remember they were also developing a single & twin seater for the navy which also looks sexy as hell!

Asraam is infrared homing, not radar homing.

Thesis about what? HAL in almost all cases, held there contractual agreements. And as it is your thesis, its of no value, because obviously you have never done any research on HAL, and how they have follewed all the contractual agreements, and which one they have violated and how much.


Thats why your thesis is absolutely terrible. AMCA, Tejas Mk1 and LCA Mk2 (and if you had done your thesis right, then you had known ADA project name is LCA Mk2 not Tejas Mk2) are projects of ADA, not HAL. HAL projects are Tejas Mk1A, Tejas SPORT, Hawk i and CATS.


Good for them.

Good for you.

Thats why its layman, and have no idea about Indian plans. Those who know about it, knows beside more orders of Rafale F4, no new aircraft is coming. You want to laugh or cry, nothing matters, but that is the situation.

Indeed.

You are just getting into semantics now, as you are very aware, my point was no country on the planet is running 3 new fighter programs at the same time, to expect India to (ADA, HAL, The Marx Brothers, whoever) is beyond the realms of reality, especially considering their tract record, the rest of your answers seem like you have no real response, so lets leave it there.

Tender for flight testing and certification of IRST on Hawker 800.

2 extra ethernet interfaces & ARINC 818 besides 1553B.

F-16 V upgrade is also based on Ethernet interfaces, to provide high resolution video.

The Improved Programmable Display Generator (IPDG) adds the ability to display high-resolution, color video on theCenter Pedestal Display (CPD). The IPDG shows color video on the Common Color Multifunction Displays (CCMFDs).The IPDG allows each display to operate alone, independent of any other display. The IPDG includes multiple coreCentral Processing Unit (CPU) technologies. The IPDG includes a new 3-dimensional graphics processor module thatis an improvement over legacy video processing. Extensive use of commercial nonproprietary standards, data busesand software provides a built-in, industry-defined growth path that minimizes the impact of obsolescence and ensuresa low-risk avionics system development program for indigenous upgrades.The IPDG includes CPU technology that allows vast amounts of data to be processed. This processing capability plansfor substantial growth capacity for future applications and data processing, as the customer’s needs change. Severalcores of the CPU are reserved for future growth, which allows for more than 50 percent growth capability.High-resolution video transmits on the Ethernet network by using Motion Picture Experts Group (MPEG) compression.MPEG is the standard used for compression. MPEG compresses the video format to the IPDG. The IPDG thendecompresses the video using industry-standard video chipsets. The IPDG displays the video on the CPD or the CCMFDs.The compressed video allows for a lower recurring cost by limiting the amount of new cable installation necessary.Future growth is easier because subsystems transmit video for display by using the existing Ethernet cables rather thaninstalling new video cables for each new video source.

So, most likely, Uttam radar for Tejas Mk2 also going to have Ethernet interfaces, for providing High resolution SAR images to pilot.

How I missed this slide previously, yeah whole backend besides FBW, and weapon release going to be based on Ethernet.

Thats why even HAL developed SDR-1 & SDR-2 have Ethernet interfaces.



Also its look like fusion engine also going to be Indian in LCA Mk2.

Their is a likelihood that Indian Navy will induct a small number of Twin seat Naval Tejas for carrier Take off and Landing training

Our current fleet of 6 Mig29KUB are not enough
And we also don't know whether the 4 Rafale Bs which the navy is buying along with 22 RAFALE Ms are going to be carrier capable.
HAL has a separate assembly line for Twin seat Tejas and they will finish Delivery of 18 Tejas Trainers to IAF in 2025

I won't be surprised if the Navy decides to order 12-18 Naval Tejas Trainer , so as to reduce the load on its limited units of Twin seat Mig29KUB and Rafale Bs

As far as single seat Tejas is concerned, Indian Navy is not going to induct that
Mainly because with 40 Mig29s and 26 RAFALES it will already have more fighter aircrafts than our two Carriers can actually carry
Also unlike the Twin engined Rafale and Mig29 , Tejas cannot take off with 5 missiles and adequate fuel load from the ski jump , due to it's low thrust single engine

That's not true at All
China has j20 running along side J35 rumours of sixth generation fighters under concept stage
Throw in mass manufacture still of j10 thats 4 projects

Then south Korea has kA21 fifth generation starting and is still manufacturing fa50

 

[harpy1]

One more thing comparing Indian military project numbers with the rest of the world is futile
India is supposed to have two new fighter projects or to be currently building forty warships over next twenty years
Ask why ,.....

Because India is the third biggest military power on the planet from now on in ...until the next fifty years plus
Why ,..
Third biggest gdp by 2030.at over 7 trillion dollars
Third biggest military budget at over 80 billion dollars already and set to double over next 7 years
Biggest numbers of naval.ports airbases and military infrastructure outside of USA Russia and china

In short India is suppose to have Tejas and Amca programmes it's normal.and expected

Just like the start of construction of third aircraft carrier it's normal for big players and India is a big nation in every sense of the word
It makes sense for Tejas and Amca and they are both coming guaranteed

So much wishful thinking on here, day to day reality on the ground always tells a different story, yet best to just ignore facts I guess.....

 

[Pataliputra]

The best course of action for the IAF would be to abandon the MMRCA program and instead acquire Tejas MK1A and MK2 because even if the MMRCA deal were signed today, it would still take at least 10 years before the first aircraft is delivered to India.
Tejas MK1A is currently in mass production, they should order around 300 of these aircraft. Additionally, once Tejas MK2 enters production, the IAF can consider ordering over 200 of them to bolster its fleet.

R-73E are somewhat long in the tooth compared to the state of the art WVRAAMs like the ASRAAM, Python V and IRIS-T. Older tech seeker and recently during one of the IAF firepower exercises, a Tejas Mk1 fired a R-73E at a drone and it sailed right past it, without detonating the warhead.

While a fighter is a bigger target and will almost certainly the radio proximity fuse will go off, it was alarming to see it miss the drone that it was able to get within a couple of meters of.

Plus the ASRAAM is more aerodynamic, without any fins that add to the drag of the platform carrying it. It also has a larger motor and a longer range of >25 kms and a more modern focal plane array IIR seeker. It is also lighter by 18 kgs than the R-73E.

With the Tejas Mk1A, the ASRAAM is the only WVRAAM that will allow carriage of 2 CCMs plus the ASPJ. If the R-73E is used, then the dual rack pylon isn't going to work.
