HAL LCA Tejas: Updates, News & Discussions

It was an old article where someone from HAL said that Tejas MK1A will be 1000kg lighter than Tejas MK1

That is not a reliable source.

The re-arrangement of LRUs would've enabled removal of ballast and also some weight optimization might have been done based on the extensive test data available from Tejas Mk1 flights. But 1000 kgs is too much.

I already gave my source for the possibility that the weight reduction on the Tejas Mk1A is 500 kgs- that came from HAL CMD's interview with Nitin Gokhale where he clearly said that Tejas Mk1A payload has gone up to 3500 kgs from 3000 kgs for the Tejas Mk1.
 
Even the GaN based air-cooled LKF601E radar's rated power is 11KW,it's higher than the biggest EL2052 radar model with 1500TRM,so what's the different?
And BTW,i'm 100% sure the radar on LCA mk1A is not the one i mentioned that with 1500TRM.:LOL:

in short

1. the chart you showed is of 1st gen AESA radar that IAF ordered for its Jaguars while LCA MK1A are getting the latest version i was informed that it had a GaA version but maybe it had a GaN version for export which i do not know of cause israel is bound by some US clause not to export it as it uses US made sub systems

2. Niether LCA MK1A nor JF17 can genrate anything close to power required to furnish a 1500 TERM GaN based AESA antenna as no single engine can produce that kind of power other than those on latest version of F16 BLK 72or F35 L II
 
Smart plane
And rather smart looking these days too

Tejas MK1A is the real deal

Tejas Mk1 is behind the upgraded Mirage 2000v5 in terms of performance

Hence the need to upgrade them to MK1a standards as quickly as possible

The Airforce will have flown the Mark 1
Against mirage 2000 Mig29 and possibly even F16 from friendly countries like Singapore or Israel ..

For the Airforce to increase orders to 180 planes now for mark 1a some of these exercises must have been beyond good 👍
 
Looks like we are indeed going for like of Viper Shield and EPAWSS on LCA Mk2, where radar is deeply integrated with other sensor suite, and able to work with active modes of jammer.

The Tejas Mk1 participated in the international exercises against French Rafale fighters in India, against F-16s at Desert Flag VIII in the UAE where UAE, France, Kuwait, Morocco, Spain, South Korea and the US air forces participated.

So definitely has had exposure against and with Rafale (both IAF and French AF), F-16s of various types as well as F-15E, F/A-18s, Typhoon (RAF), Mirage-2000s (IAF as well as UAEAF).

The IAF conducts regular DACT for the type against all other types in it's service. It for sure knows what the Tejas platform is capable of.

The picture is one of my favourites of Tejas
It looks like a proper genuine fighter so easily assume it's french built.
Looks like rafales
younger smaller brother

I would love to know how Tejas mark one faired in excercises

whats the power generation capacity of the rd93?
 
not power output- the power generation capacity @Guru Dutt, i await your reply
be it GE 404 or GE 414 or fpr that matter RD 93 they themselfs do not make power but support a auxilarry unit /comressor/genrator which without putting any starin on actual power or airflow/thrust capabilities makes elctricty power like a alternator on your car which powers the electicals of your car/vehicle like A/C and lights or sereo

here since RD93 is a bit underpowered and older technolgy though upgraded still not on par with the GE 404 or $!$ its like compairing a naturally aspirated petrol enine of a 1.2 litrethree cylinder car engine of your suzuki with naturaly aspirated 1.8 L in line 5 cylinder car engine of baseline BMW .... what will be more powerfull and have a better AC and better pickup ....???? though there is not hell of a difference between the wieght of 1.2 L engine and 1.8 L engine and the later gives identical fuel efficiency as the former too

Can you tell me the power output why are you dancing around it? What is the power output, pretty simple question lol. Were not talking bmws, were not talking car engines, im asking you a simple question, what is the power output?
