And we are doing these backward somersaults because some people in the media - and that includes manufacturers and supporters of the Gripen have told us that Gripen has a range of X and Tejas has a range of Y and X>Y and we believe them. Why we believe them and set out to try and do some "skyentifik kalkoolasons" to prove or disprove some obviously fragmentary and likely biased information I have no clue.

But lets not stop. Lets carry on and pretend that something is going to come out of this.
Hakeem,

Anybody with a semblance of knowledge of aerodynamics would tell you that under cruise conditions (1G load), almost all fighter jet aircrafts have an L/D ratio of within 10% of each other. Don't forget that aircrafts can have different cruise speeds to minimize L/D. But they are all so similar in shape that all of them cruise at near 0.8M for best L/D at 1G. Anybody who tells you otherwise is simply dumb, biased or has to sell you something. And that is why I was so ticked off by the presentation. IAF is not dumb. Neither does it have anything to sell. It only left out one option.

I want to blurt out Tejas's meaningful range. But I will wait for the actual flights to be reported in public before I discuss it here. Even Mk1s figures are comparable to any light fighter, including the Gripen and F-16.

That can't be right. You mean a bunch of third world, Yindus, with no accented English, can develop a fighter that rivals the best (or is it west). Cant be. Sorry

1. The Arjun is operated by more than just enlisted man. The tank commander is usually a commissioned officer and said that I have found the attitude of the enlisted man to be more sympathetic and/or open to equipment. The Indian jawan has more confidence in himself than it surfaces across. Would you agree or disagree ?

2. Now on the Tejas, the equipment is also operated and diligently worked upon by a lot of techs who may not have a space and a role on board the aircraft but it does not mean they are any less detached. Would you agree or disagree ?
The point is, Air Force officers gets a lot of say (and ears) about their equipment than their Army counterparts. There are many reasons:

1. Small numbers of users. All officers.
2. "putting his life on line" carries a lot of weight. Do we say a Tank commander "putting his life on line" (for non-combat work)
3. Higher visibility.
etc.. etc.
Point well made especially in regards to putting life on line.
I accede.

I can discuss things which are demonstrated in the public domain. There have been numerous flights where the Mk1 has directly flown from Bengaluru to Jodhpur with two 1200 ltr DTs. I can tell you that they land with hundreds of kgs of fuel still left in them.

I told them to take it up with FB. Apparently FB has no way to say which was is legitimate. I told them that is numbers are required to prove ANYTHING, our entire member base will rally for the cause.

They should host their own page and then link it to FB.. Even if FB goes down, it should not impact people wanting to track Tejas.

Tejas-India's MRCA page actually posts a lot of stuff, but they also post entire articles written by others without giving credits. Such a shame that they would actually have the temerity to accuse LCA-Tejas FB page of plagiarism! Considering that LCA-Tejas FB actually posts original Tejas content, not Tejas-India's MRCA page.

Better quality pic of the one that I'd posted earlier. Luckily I'd saved a copy of this image before the LCA-Tejas FB page went down.

Looks so ready to take on ORP duties, and it can, now that its confirmed that Derby BVRAAM integration is complete.

^Such a beauty. But definitely not comparable to NLCA.

I am still trying to recover from cancelled NLCA Mk II. May all your lungis get permanently twisted when you do lungi dance without a token sympathy for NLCA.

I know. But the problem is not solved. They waited for FB to respond. FB hasn't responded, so they went back on with the reported content missing for the moment.

The bandook has always been integrated. But in this picture you are seeing the camera mounted in front of the bandook to capture the flight path of the missile in front of the aircraft.

We never hear any of these details when it comes to aircraft like the J-20. Everything gets magically done, and seemingly perfectly.

I was about to post the same. For all its criticisms Tejas has emerged only stronger. It is the only way to tackle a 2 front war and stop the import gravy train

Btw I asked this question before - Tejas grew a spine few years ago, but the bulge around the spine, leading to the wing, is it new?

They have flown supersonic with the refueling probe. They have hot refueled. They just have to show dry contact with a refueler. That should not be a problem.

The envelop has been completely opened. There are some last few FCS upgrades left to be buttoned up.

The gun has been de linked from FOC. The problem is not with the gun or the aircraft. IAF has to figure out the next course of action.

FOC is firmly in sight.

No sir, the spine and the upper wing-body blending has been there from the first day.

In RaGa lingo problem when the gun and a/c come together!

Indranil , I think DRDO should come up with own WVR missile for IAF.

Long ago the AA-2 was being made in HAL Hyderabad.

if the GSH23-2 is too powerful and vibratory, i wounder if the 30mm defa cannon on jaguar could be used?

the DEFA is single barrel
Rate of fire 1,300 rpm
Muzzle velocity 815 m/s (2,670 ft/s)

GSH23-2
Rate of fire 3,400-3,600 rounds/min (alleged)
Muzzle velocity 715 m/s (2,350 ft/s)

the DEFA is also heavier hence will not vibrate as much 85kg vs 50kg
it is already used in our Jaguar and Mirage2000, so we understand it and service it.
