https://twitter.com/hvtiaf/status/12782 ... 31648?s=20 ---> Tejas Mk-2, TEDBF & AMCA D&D in progress in India by ADA. Not sure what strategic benefit an imported 4th gen aircraft would provide in the future. Happy to learn about any specific merits please.

https://twitter.com/hvtiaf/status/12782 ... 23682?s=20 ---> Excellent is the biggest enemy of good. The Indian fighter aircraft is Good. Many new variants on the anvil. Time will tell, which ones will prevail. Perhaps we'll be Excellent someday. Full regard for voices of criticism against Indian products and agencies.

https://twitter.com/hvtiaf/status/12783 ... 94528?s=20 ---> Tejas is a huge strategic achievement. Every foreign competitor is at his wits end, trying to bring down the Tejas success story. Not going to happen. Tejas has already endured enough onslaught from outside and within.

When HAL's product development is inextricably linked to MoD, funding delays are bound to happen. HAL should raise $5 billion from open market to fund product/MVP development, only then we will see massive ramp up otherwise this rona dhona will continue ad-infinitum

'Flying Dagger' Tejas Mk1 with Derby, R-73E and 2 drop tanks. The first known pic of an operational Tejas with the Derby!

Nice!

So that would mean IOC aircraft are already getting FOC upgrades incorporated.

Hopefully. Need to see an Elta ELL-8222 SPJ as well and then the fleet should be at a point where No.45 Squadron can move to a forward air base or at least detachments can be sent out.

From HVT's Twitter feed. Looking good!

The next decade will see this becoming a more common sight as more Tejas Mk1 and Mk1A fighters join the IAF.

Older prototypes, not Series Production Tejas fighters. Those aren't Cobham radomes.

At least 200 of these are needed as of yesterday! Much cheaper than buying the Russian and French lawn darts. The PLAAF and TSPAF combined can't take on the IAF!

Russian and French lawn darts? TBF, the attrition rate of both the Su-30MKI, MiG-29 as well as the French Mirage-2000 is very respectable.

I don’t think SPJ would dictate forward deployments. Historically, most IAF fighter types didn’t have SPJs. Even those that have SPJ option don’t always carry it. WC Abhi’s MiG-21 Bison didn’t carry one during post-Balakot air action.

For a point defense fighter located very close to the border and intercepting enemy fighters at short notice and distance (within 20 km), SPJ may not always be useful for combat. WC Abhi’s MiG-21 was engaged at less than 10km, while he shot down F-16 at around 18km. All within visual combat ranges.

That was a very specific scenario though. The combat may play out very differently the next time. They need to get it integrated asap. Not sure what the delay is exactly. Maybe someone can ask that to HVT sir on Twitter.

SPJs and LWRs are absolutely needed on all platforms moving forward. As for our bison, all I’ll say is, if there is one aircraft which continuously surprised our mock “adversary” in umpteen simulated combats with foreign Afs its the bison. That being said, I also strongly feel it’s time for the bison to hang up its boots and for Tejas to take over. Do watch the fighter pilot podcast with bundal Tyagi on the mig 21 here:

Tail number isn't visible, but where the Main Landing Gear doors are, one can see the number '14'. That's SP-14, with the 'Flying Daggers'.

by part yes, by cost LCA is still 50% foreign. And you can see the dilemma, as we develop more, what is left will slowly become slightly costlier. Another way to look it is that unlike China, who do not have access to the best in world, we have some access (mainly to European/Israeli if not US system) and we are buying the best of subsystem that would make LCA all the more lethal
-Engine (no choice, but F404/F414 is best in class)
- Radar (2052, better than in development Uttam, key word in development, cheap, less effective than costlier French radar)
-EW/Helmet etc.
- Actuators (do we make them? or imported from, Moog?)

Actuators..Yes by Godrej.

The LCA Tejas isn't just about protecting our nation. It's about doing it ourselves.⁣

At Godrej Aerospace, we gave the Tejas, the multirole light fighter, another boost in the wings by manufacturing the first Indian aircraft actuators. These actuators, designed by ADA/DRDO, were successfully tested across all altitudes and speeds of operation, on the 28th of May, 2020. ⁣

Congratulations, India.⁣

That is what causes the greatest takleef and heartburn to the OEMs and to some on the forum.

Some of you are extremely good at picking up innocuous looking details, and you probably take it for granted that some things are obvious. In this example, an operational detail is involved... At a sensitive time like this, it might be better to rejoice quietly.

Did not the belgium parliament? debate/deny? the sale of some actuators? hydraulic?

Well where is belgium now? Full of 5+ presidents of the EU and islamics = worthless

So IOC aircraft are BVR capable but restricted to Derby, while FOC aircraft probably can carry Astra and Derby ER.

Derby is available for LCA. Integration trails have not started yet for Derby ER and Astra for any version of Tejas.

Another difference I can think of is that the FOC birds seem to have a White covering for the Radome compared to dark grey for the IOC aircraft.

Not really, I think (unless they are happily changing tail numbers andcolous!). See this:

I was not sure if the gun, like IFR probe, was plug-n-play. Khalsa has hawkeye to see 14! I had trouble spotting it on my mobile. :)

These are evidence that IOC are getting FOC upgrades (possibly as when available). We are seeing BVR Derby and Cobham radome on IOC squadron LCAs.

It appears that they are prioritizing upgrades over delivery of FOCs. If it so then it shows lack of manpower.

Or maybe they want full foc aircraft available if the crackers go off.
The assembly line is not read for FOC upgrades which are mostly software related yes?

It is possible that most of the changes could be done at the airbase itself. It may be as easy as taking out an LRU; installing a new software update, or if hardware then replace the LRU; and putting it back in. Reboot the system; run diagnostics; and it’s ready to go. After all, LRUs are supposed to provide this sort of plug-and-play advantage.

Gun and IFR may require more internal structural modifications. These will need to be done at HAL at some point.

Cobham radomes have been in use since the last couple of LSPs itself. All IOC jets always had it.

And they’re light grey, not white as some other poster remarked they were.
