Yes. Also, I think that if the french do not back down, at least for the israeli radars(Tejas), then it will kill any chance of further purchase of Rafale.

That is the story of nearly all Indian defence negotiation. I am hard pressed to find out the exception to this.

It's basic knowledge that every optionality has a price. Whether we want to pay for that must be determined in advance. It's also a fact that not all options that are paid for need to be exercised.

Indian negotiators are tasked to minimise the price of deal at hand because in the end that'll be scrutinised in public domain.

There's no point in criticising. Govts would fall if in Indian context we're found to have paid for but not exercised an option.

There might be a possibility that IAF wants to use meteor with only Mk2 fitted with Uttam and not 1A. Mk2 ultimately is more suited for interceptor role.
For 1A they are considering Astra which will be more suited for occasional firing of BVR in point defense role, so they do not care if MBDA does not want them to integrate Meteor elsewhere. Also by next 5 years we will also have SFDR Astra.
Saves cost, hassle, indigenous effort and makes everybody happy.

For LCA Navy, we went with a two seater design with the rear cockpit used for avionics & possibly additional fuel. The same design element was used for MiG-29K and possibly carried forward in MiG-35 that takes MiG-29K developments (paid by India) to land based fighters.

So whenever you see this design, remember Indians came up with it.

Is this a joke ?

The Naval LCA prototype first flew in 2012 while the 29k entered operational service in 2010. The F4 phantom which flew in 1958 had an aft seat RIO, and I am sure you could come up with more examples. The F15 had a front seat wso . Front seat vs rear seat are at junior school levels of obviousness

I'm no missile expert but Meteor should only be used on front line fighters with long range and high load carrying capacity.

That largely excludes it's usage on Tejas MkX.

Anyway India should be careful about further purchases of military equipment from Europe which may restrict usage to narrow bands.

to really chase off chinese heavies ( transports, ELINT, tankers, AWACS) from their orbits over tibet, we need a solid fuel hypersonic missile of 1000km range so launch platforms can climb safely on our side to 50,000 feet before releasing them on their long climb to 200,000feet and back down.

but first a means to surveil and track a.c deep inside tibet over the himalaya has to be tested and proofed. ground based HPR are cued to high alt BMD targets and cannot detect manned platforms flying much lower. the aussie jindalee oth seems all bark and no bite. could not even track a big lumbering malaysia 777....and they talk of tracking ships in the north pacific.

some new basic research is needed on this theme.

AWACS will have emissions, the rest will have little to none.

What he meant is starting with a two seater design and converting it to a single seater by converting rear seat for additional fuel or avionics.

He drew on the meteor discussion..and is pointing out its limitations..

IMO, not integrating Meteor on Tejas and Su-30 is but expected as it takes away a big reason for India to buy Rafale. What did we expect, MBDA which is tied at the hip to the French state and Dassault, will just acquisce to our needs? Its like expecting Thales will put a RBE-2 and Spectra derivative on the Su-30.

This is exactly what makes Israel such a valuable partner. They have no qualms in integrating whatever system on whatever platform. We have Israeli avionics on Su-30 if I am not mistaken and for Tejas, radars, missiles and quite a few subsystems.

They are opportunistic like the rest. If they had a plane to sell, they would behave the same as the French.

Would it be a good idea to combine thw Rustom project with the unmanned Tejas? I don't see what an unmanned Tejas can do that a UCAV like Rustom can't. This might help make more funds available to the project as then we will be funding 1 instead of 2.

From Tejas-LCA FB post ...
LCA Tejas Programme achieves another accomplishment:
The Tejas programme achieved a rare distinction by completing 4000 Successful Test Flights today. All the flight tests and aircraft instrumentation related activities are planned, coordinated and executed by the National Flight Test Centre, ADA in Bengaluru. NFTC has experienced Indian Air Force and Indian Navy test pilots and flight test engineers along with the scientists and engineers for telemetering the regular test flying activities in real time in an extremely controlled environment.

Not at all! The Rustom can't fly and fight in contested airspace until and unless it flies high enough that an enemy with only VSHORAD/MANPADS can't attack it, an unmanned Tejas may well be able to, especially if it is armed with a proper self defense suite. The Tejas will fly and maneuver at several times the speed of the Rustom and carry a much heavier payload! On the other hand, the Rustom is designed for extreme endurance, a day even and hence an entirely different mission capability.
Both systems complement each other and can't replace each other.

It's not clear from that paragraph if there truly is going to be a Tejas design without a pilot, or if the airplane will be used to create unmanned flight capabilities. It makes a lot of sense to develop these capabilities with a pilot still available to train or take over from the software. It will also be extremely useful for manned airplanes to execute automatic ingress, attack, evasion, etc. leaving the pilot to deal with battle plan management, target designation, etc. All in all, very exciting.

Boss .. you answered it .. matter of fact when you have standoff weapons at extreme ranges (Sukhoi with an x range brahmos for eg), all it needs is targeting data ..from drones or unmanned fighters! .. the manned fighter could be in home airspace

DRDO notes it is making Uttam, Digital RWR and SPJ for Mk1A. If HAL wishes, it can integrate them on the Mk1A.

Great move. At any rate we have systems available for Mk2 and also, can fob off arm twisting from the Israelis or whosoever.

I think what he means is that they have received the approval to prove out technologies required for the Ghatak UCAV using LCA as a test bed. They will prove out ATOL first. The manned pilot will be there as back up. I think this is a brilliant idea to mitigate risk. The final UCAV will have flush air data sensors. As will Mk2 and AMCA. But AFAIK flush air data sensors are still in development.

I heard the current Tejas Squadron is moving out soon (end of month or so).
Will this be post FOC and if so, where will be the next squadron based.
If I remember correctly, its the Flying Bullets Squadron correct.

What you need is a custom AAM mounted on one of our old Agnis with a radar or IR sensor on the Agni to provide the initial guidance. Hell, mount three or four AAMs - the missile can carry that many - to ensure that the target is destroyed for certain.

Not completely. ADE still doesn’t have a full proof ATOL.

This one is being developed by an ADA team. They can leverage from the Navy program. LCA Navy takes off from the jet ski in a completely hands off manner. Some aspects of the landing is also automated.

There are some other teams too who are doing ATOLs for fixed and rotary wing designs. In the private, public and academic sector.

Missile on a missile? Is that even feasible? How will the AAM know when to detach? Missile seeker is not the same as aircraft radar, the range is severely limited.

What about the economics? It would be too costly to launch an Agni-5 every time we want to take down a transport/AWACS aircraft.

Not me. I believe that Tejas was delayed due to lack of clarity from the government rather than any design issues with the aircraft.

A bit of foresight in early 2000 could have resulted in a functional and serviceable fighter by 2007 or 2008. Such as using the mission package developed for mig 21-93 or something similar. While not cutting edge, would still be a lot better than what we had and still have in service.

On an easy to fly and maintain aircraft.

While domestic mission package gets deployed in a subsequent iteration of the plane.

An approach of this nature would have given us at least 200 jets in service by now.

I don't think IAF would've accepted it. Those were the days when there were plans to induct 200 rafale. No way IAF would've accepted a sub-standard Tejas.
