HAL LCA Tejas: Updates, News & Discussions

JF-17 first flight - 2003 (180 planes in service)
But yeah, keep blaming GE....
Comparing the Tejas program with your JF-17 is laughable at best. Let’s set the record straight. HAL has produced 222 Su-30MKIs between 2004 and 2020—aircraft that are far superior to anything in your fleet. And guess what? Those Su-30s come with more indigenous content than the glorified assembly line you call the JF-17, which has almost zero Pakistan-designed components. It’s pretty bold to talk about ‘production’ when all you’ve done is bolt together Chinese hand-me-downs.

Meanwhile, HAL has also delivered over 400 Dhruvs and its attack variants without a hitch, setting the standard for indigenous helicopter production. Where's your homegrown equivalent? Oh, that’s right—you don't have one. You might have 180 JF-17s, but you’re still entirely dependent on China for parts and expertise. Tejas, on the other hand, is a fully indigenous project, designed and developed in India, not a rebranded export product. There are three critical components for any fighter jet: fly-by-wire systems, radars and avionics, and engines. India’s Tejas has mastered this with a quadruplex fly-by-wire system, the Uttam radar, and Indian-made avionics. We only import the engine and ejection seats—standard practice for even the best jets out there. Recently, India developed Leading Edge Actuators and the Airbrake Control Module—key secondary flight controls for the LCA Tejas. Plus, critical LRUs originally designed for the Tejas Mk2 are now being integrated into the Mk1A, significantly boosting its flight safety levels. We’ve even got our own Astra BVRAAM to arm it with.

Meanwhile, your JF-17? It’s basically a Chinese jet with some local touches. No fly-by-wire designed by Pakistan, no radars, no avionics—just assembling what China gives you.

The JF-17 might be a dime a dozen, but quality beats quantity every single time. So before you even think of comparing your knock-off jets to the Tejas or anything else HAL has produced, maybe you should first try building something on your own—if you can.

No, right now no MK1A is replacing MIG-21, and even HAL are now saying they may deliver one in November 2024 (which in normal time means November 2025 going by HAL standards)

delay ? Not an major issue,

HAL was needed to deliver 17 Mk1A by the end of FY 2024-25, but till end of August 2024 not a single delivered that means short delivery of 8 planes, even if they didn’t deliver any plane end of this year, then also they can make it up by raked up production from 8 to 10 at Nashik production line and 16 to 18 Bengaluru production line i.e., additional 4 planes every year so complete delivery of 87 Tejas Mk1A by 2028, they might get delayed by 12-18 months but not more further.

Further, considering follow-up order for 97 planes and plans of LSP of Tejas Mk2 since 2030 chances of increased production of 20+12=32 from FY 2026-27 is also possible.

Again, you are simply qouting HAL now, as we all know, the delay is exactly why the IAF finds itself in it's current predicament.

New production lines have not even STARTED to be built yet, but you are now qouting these non existant lines building imaginary planes.

Every year of further delay means an older and older IAF. Any serious observer of India Air Power would simply be alarmed that in the first time in IAF history it has not received any new planes in last 2 years.

HAL is the producer, developer and so quoting them means it is the authentic source compared to any other.

HAL has 2 production line at Bangalore and third one at Nashik factory each one capable of producing 8 Tejas p.a.


40 Tejas Mk1 delivered in last 2 years and Tejas Mk1A suppose to be start delivery by March 2024 and we are still in 2024 I think.

No, again, you seem to lie with a straight face.

Only 35 planes delivered (5 trainers remain undelivered due to issues), first MK1A expected in Nov 2024
 
The delay is due to the consideration of using the Kaveri engine instead of the GE-F404 in the Tejas MK1B. Although GE has stated that they can scale up production to 24 engines per year, the potential switch to the Kaveri engine is causing the hold-up.

There is not going to be any switch to Kaveri in the next few years. It is not a proven engine, especially not for single engine fighters like the Tejas.

There is no hold up either. That is just fake news. The GoI will now want GE to set up some sort of a final assembly line in India for the F-404, given that GE will get at least 110-120 F-404 engine orders with the next 97 Tejas Mk1A batch.

Design by Dassault, FCS by the US as well as the engine, Israeli radar, you even had to get the radome designed by Cobham in the UK because the one made by indians was causing too much interference with the radar and other avionics.

Yes, the Tejas initially utilized expertise from global partners, but that’s part of how complex aerospace projects develop. The key is not just the initial help but how we’ve leveraged it to build our own capabilities.

For instance, the Tejas features an advanced quadruplex fly-by-wire system that was designed and developed in India. This system provides superior control and reliability compared to the older, less advanced systems you’ll find in the JF-17, which heavily relies on Chinese technology. Similarly, the Uttam AESA radar, another Indian innovation, outperforms the Chinese KLJ-7 radar used in the JF-17 in terms of range and capability.

The Block I and II have hybrid analogue/digital FBW with quadruplex digital in pitch, while Block III has quadruplex digital in all three axis. Please demonstrate how the FCS, which was heavily designed by the US and Lockheed Martin in tejas is superior to "Chinese technology". So you're comparing your "uttam" AESA radar with KLJ-7 PD radar? What about the "uttam" with the KLJ-7 AESA in the Block III? How do you know the "uttam" is superior to the KLJ-7 AESA?

The FBW system in the Tejas is a fully indigenous innovation, designed and developed by Indian engineers, and India owns the IP rights for it. The LCA Tejas has had a quadruplex FBW system right from the start. This means it's always had advanced control systems in place. And this isn't just a static feature—India has been continually upgrading and refining this FBW system, with even more enhancements on the way. This reflects the high level of expertise that Indian engineers have achieved in aerospace technology.

This is something the JF-17, with its more maintenance-prone air-cooled radar, can’t match.

India's progress in radar technology is evident, with indigenous AESA radars already deployed in systems like the Netra Mk1 AEWCS, and more installations ongoing in Netra MK1A and MK2. This level of development shows that India’s capabilities in radar and mission system integration are not just competitive but ahead in several areas.
 
Kaan, Rafale, F-35, JF-17. No one had issues with engine supplies, thus is my point, it's bad project managegment
Of course, and why go outside SU 30MKI a large acquisition had no such issues as well. It was done by ourselves, and pretty smoothly.

Planning things on the fly results in what we have now
 
All that BS about there being a hold up in the next 97 Tejas Mk1A order is called out here in this article from Economic Times, which is much much more reliable than IDRW.

US firm behind delays in Tejas Mk1A deliveries to IAF

According to a recent Financial Express report, the contract for additional LCA Tejas Mk1As, estimated to be worth Rs 67,000 crore, could be finalised by the end of the year. If awarded, this contract would be the second major order for the LCA Mk1As, following the Rs 48,000 crore contract for 83 jets signed in February 2021.

..

HAL has reportedly assured the IAF that it will deliver 16 LCA Mk1A jets during the financial year 2024-25 (FY25) and complete the delivery of all 83 by FY29.
HAL has also established a new production line in Nashik to meet the increased demand for the aircraft. This new facility is expected to boost production from the current 16 jets per year to 24.

..

According to the report, HAL's management expects the delivery of Tejas Mk1A jets to commence in the September quarter of FY25.

Citing a Nomura India report, the news report said that with regard to the delivery of the Tejas Mk1A aircraft, supply chain disruptions at GE Aerospace have caused delays in the delivery of the F404 engine.
The report said that while GE initially planned to deliver 16 engines annually starting in FY23, as of August 2024, none had been supplied.

This delay, according to the report, has postponed HAL's delivery of the LCA Mk1A.
As a result, Nomura India had previously reduced its LCA Mk1A delivery estimates from 14 to 10 jets in FY25.

..

In its Q1FY25 conference call, the management of Astra Microwave Products, a private Indian firm that builds sensor and defence electronics components, had highlighted that despite the delay in supply of GE F404 engines, there might not be significant delays in the delivery of the 83 Tejas Mk 1A jets by HAL.

According to Astra, HAL has an alternative engine replacement and could still meet the contractual timeline, albeit with minor delays for some aircraft in FY25.

US firm behind delays in Tejas Mk1A deliveries to IAF
There are two kinds of problems going on in tandem here

One is the delay of engines by GE due to supply chain issues, and GE revised their supply timelines. This actually means we didn't plan for local production when the deal was negotiated with GE, which interestingly was negotiated by Airforce instead of HAL apparently. This delay has pushed the 83 TEJAS Mk1A order delivery schedule further as well. Airforce and HAL used this delay to add some new LRU and update software issues, that needs re-certification (Which is not a bad thing). It however shows improper planning while negotiating for the engine on our part, which they seem to have worked on during F-414 at least.




The second problem is every tom dick and harry reporting on Defense these days, adding their own Masala. For example the delay or hold up in 97 additional order, its actually crazy to say this because the deal with HAL has not even been signed yet. So how can anyone say that there is a delay or hold up? Its just news manufacturing.

Given the way Defense matters are communicated in India, and how HAL never sticks to timelines.. such manufactured news is easily gobbled up.

You simply asssembled SU-30s, makes no sense
