LCA TEJAS MK1 & MK1A: News and Discussion

[vin bharat mahan]

Buck vs bang... MAWS is limited by range. You'll invest a lot of money& not get any output unless the missile is being fired with 5km-odd range.
Thus all helos are getting it as they'll need it. For high flying jets only the top-tier will get it

....if MAWS hv limited range...that doesnt mean WVR missiles with infrared seeker hv also limited range. python 5 hv 25-30 km range nd ASRAAM hv 40+ km range. so all aircraft need it, by help of MAWS u can find out that enemy fired IR missiles for u. than after u think about use of flairs. without MAWS how can u find out WVR missiles??

Python 5 has a 25-30km kinetic range, which doesn't mean that the guidance seeker head will actually track that far away in real conditions

these WVR missile guided by aircraft IRST sensors also....i read a article which said that ASRAAM will give tejas mark 1 nd 1a 40 km approx infrared sensor range. so tejas mark 1 nd 1a dont need pod based IRST system. so definitely these missiles sensor hv 25-40 km IR sensor range.

these WVR missile can guide by aircraft IRST sensors also.....python 5 also integrated with tejas mark 1 nd 1a, which hv no IRST system. so u r telling that python 5 will only target other aircraft for some kilometre, but not from 20-25 km?? i read that in some operation pilot turn off their aircrafts radars also, so they didnt caught by enemy RWR nd radars. that time IR missiles give them 20-40 km range to fire. so definitely WVR missile hv 20-40 km IR sensor range. thats why ASRAAM is integrated in tejas mark 1 n1a, so it can give little IRST capability also.

This is the issue... Unless the dual reach is here ASAP, it'll carry only one single CCM.

ASRAAMs with dual rack are slated to be there on the Tejas Mk1A eventually. Once that happens, this won't be an issue. But as of the 2021-22 ADA AR, there was no mention of what the status of this project was.

Everything has unlimited range based on target signature


If you shoot missile at sun, it will easily trach the sun which is 150 million km away

Same way, if you shoot at the tail of an aircraft that is full afterburner, quite possible it is picked up at many dozens of km

But regular aircraft, flying subsonic coming head on wont be picked up till max 10-20 KM away unless you have good IRST, since bigger sensor+computing needed to differentiate target from environment.

BIG NEWS!! Finally Kaveri Engine to be Integrated with LCA Tejas

BIG NEWS!! Finally Kaveri Engine to be Integrated with LCA Tejas

What's it's persent weight:thrust specs?

 

[Corvus Splendens]

What's it's persent weight:thrust specs?

Around 75kn with afterburner.

 

[Bleh]

Around 75kn with afterburner.

That's the old Kaveri, problem ridden... There's no chance were replacing a 98kN engine with a 75kN one.

 

[Corvus Splendens]

That's the old Kaveri, problem ridden... There's no chance were replacing a 98kN engine with a 75kN one.

The one with an M-88 core can do 90kn with afterburner.

 

[SwordOfDarkness]

That's the old Kaveri, problem ridden... There's no chance were replacing a 98kN engine with a 75kN one.

Of course you can, just wont get optimal performance

Infact, empty weight this is more than 1:1

(Also note, GE404 is just 85, not 98KN max thrust, so reduction isnt much)

IRST has advantage only when your Radar is off. It can passively scan around 100 KM. If your Radar is on, missile can be guided by Radar. When it reaches near aircraft and IRST starts sensing the heat and operates in Autonomous mode.

HAL CMD Interview:

HAL CMD confirms that Tejas Mk1A is on course. Only 3-4 systems yet to be certified by CEMILAC, will be done in next 2 to 3 months. Rest all have been certified. First Mk1A airframes have been almost built & will go in for equipping soon. On course for delivery to IAF starting Feb 2024.

They are targeting to build 24 Tejas Mk1As from 2025-26 onwards and can even ramp it up further to 30 per year if they can streamline their suppliers more.

Ramping up capacity, prepared to execute big orders says HAL Chief

New AESA and other electronic are fine but what about aerodynamic improvements and weight reduction, improvement in transsonic acceleration etc. ?

i hv 3 question regarding aircraft, if anyone know plz reply:-
1:- what type of data link (like american link 16) we use to get data between our different aircraft...is data link nd SDR (software defined radio) r same thing, coz both help to transfer data between aircrafts.
2:- i read american nd typhoon etc aesa radars can also do jamming....can elta 2052 nd uttam aesa radar also can do jamming stuff??
3:- towed decoys can mimic aircraft radar signature...so it can save itself from enemy RF (radar frequency) seeker missile. so why cant we make a towed decoy also, that can mimic aircraft engine heat?? it can be good counter for infrared WVR missiles.

1. Data link - IAF uses their own data link,ODL . Data link is a communication technique & SDR is a communication device, its like 5g nd iphone
2.No, under development
3.We can make them for LCA mk2. Not good against IIR/EO missiles. Indian Rafale, EFT, SH having towed decoy
Link The IAF is still miles away from being a truly networked force

I may add a pointer that too much reliance on technology got Israelis in trouble on October 7th. Their Iron Dome and other systems were found to be useless when a mass of rockets were fired at it. Similar things are happening in Ukraine where much-touted American weapons were supposed to expel Russians from Ukraine. Instead, Russians have not vacated an inch of territory with all these technologically superior weapons.

My point is that the human behind the weapons does the job better than relying on technology only to do the job.

Not replacement.

This is to certify the engine.

Israel already knows and said iron drome is useless against a major attack, a major reason why they are developing iron beam, DEW
US already mentioned that, it is impossible or very hard to retake occupied territory and US also against a direct attack on Russian main land. Giving money and weapons keep Rus-Ukr war alive, which result in economic problems to Russia and to understand capabilities of Russian weapons. win-win solution for US.

My point is that the human behind the weapons does the job better than relying on technology only to do the job.

True, and here no one is talking about AI, and !00% controlled by humans, 0% machine
