That's Israeli. Here is the Sudarshan.

The development of the kit has matured to the level of guiding the bomb within 10 m CEP from its otherwise 400 m to 1000 m fall-off the target. The extension of kit’s capability to further increase its range using global positioning system (GPS) INS is on.
Any further news of this extended variant?

Interesting parts on Kaveri by Dr.Subhananda Rao

Kaveri engine, after successful completion of official Altitude Testing, was integrated with Il-76 aircraft at Gromov Flight research Institute (GFrI), russia and flew for 57 hrs at max altitude of 12 kms and 0.7 mach no. With this the performance of Kaveri engine in flight was
demonstrated.

After the analysis of this performance, the engine will be fine tuned and final version will be realised in the next one year. After certification for 100 hrs flying by cemIlAc, Kaveri engine will be flight tested on lcA.During Kaveri engine development programme, the design and analysis
expertise has been assimilated by GTre; critical sub-systems have been designed and qualified; 12 different materials have been developed and certified through midhani and Dmrl.

Kaveri has got spin off applications in development of marine version of gas turbine and can also be a candidate for future unmanned missions.

Regarding Kaveri snecma, the detailed discussions have been held; development plan, technologies, terms & conditions have been finalised. Negotiations are in final stage and are likely to be completed in the next 2-3 months. Afterwards papers will be moved for cabinet approval.

On Rustom1/2

ADe has successfully developed Pilotless Target Aircraft lakshya-I which can fly at a speed of 300 km/hr for 45 minutes. Three ervices have already placed order for more than 50 aircraft. later lakshya-II was developed which flies at higher speed of 700 km/hr at altitudes as low as 25m with complete digital electronics. user Trials were completed and this will be inducted shortly into the service.Nishant uAV was developed with payload capacity of 60 kgs and endurance of 4 hrs. This was accepted by the services and they have placed the orders for ore
than ten aircraft.

With the success of Nishant & Pilotless Target Aircraft (lakshya), DrDo is taking up development of various medium Altitude long endurance (mAle) uAVs namely rustom-1& rustom-2 for the users. rustom-1 is under flight trials with eight successful flights including the maiden flight with electro-optic payload on 8th Dec 2011. Through rustom-1 we have been able to demonstrate the conventional take-off and landing along with way point navigation.As a matter of fact rustom-1 programme was taken up to perfect the technologies viz, external pilot assisted
take-off, automatic nose wheel steering, developing systems for long endurance, trying out design aspects of data link which will go into the rustom-2.
rustom-2 has been sanctioned by government in Feb 2011 and since then significant progress has been made to almost finalise the design of most of the systems. The integration is likely to start in 2013 with first flight by Feb 2014.

Shri PS on the LCA

On the LCA Tejas programe update:
We have completed initial the operational clearance (Ioc), which means the aircraft is ready for service. After this, it is the final operation clearance (Foc). but we have decided to include another stage – user evaluation Trials , an intermediate milestone before the Foc.In this stage, we have to integrate some new features with the Aircraft such as bomb, new drop tanks and also we are trying to expand the flight envelope in terms of another two degrees of angular attack.

Also based on the flight testing that we have done so far, the pilots have given us several valuable inputs as to how the pilotvehicle interface has to be improved. The Pilot Vehicle interface is a very important element in the design of avionics and flight control system of an aircraft. This should be very friendly for the pilot in terms of reducing the workload and giving him the best comfort when he is flying the aircraft
through critical and demanding mission.This PVI (Pilot vehicle interface) improvements normally emerge only after the pilots carry out the actual missions and then identify the deficiencies and suggest improvements. We are currently going through this important phase. Also an
Autopilot is very useful function to reduce the load of pilots in certain phase of flight. This autopilot has been accomplished and was made available to the pilots for evaluation. The autopilot function has been evaluated and valuable inputs have come for finalizing this function to be
used by the operational pilots.

Also another important feature towards the carefree maneuvering of the aircraft by the pilots is also getting evolved carefully.In addition to this, certain refinements of general electro mechanical system will be carried out to make the aircraft more user friendly or maintenance friendly. These are the activities which are currently in progress. Also, several activities which are required for final operations clearance are
also concurrently in progress.

On LCA Tejas Navy:
The naval aircraft is undergoing the ground testing towards the low speed/high speed taxi trials. After completing these trials, the aircraft gets cleared for the flight. The new feature of this aircraft which are not on the IAF variant like strengthened under carriage, leading edge, Vortex control devices etc. demand additional testing facility for the safety aspects.Also this being the first aircraft of the naval variant, the rigor with which is testing is conducted is higher than that of the normal production. Any observation during the testing related to the safety has been of utmost importance so that the aircraft is safe to fly. It is proposed that the aircraft will fly this month after going through all formal clearance process

Progress on advanced medium combat aircraft and the next milestone and the time-frame:
The advance medium combat aircraft are one version of the preliminary design that has been completed and the performance aspects are
being discussed with Indian Air Force. based on the suggestions, further improvements will be carried out and after completing the
feasibility of an acceptable design, we will approach the government for the full fledged funding for the design, development, testing
and the certification of the aircraft. before the middle of the next year, it will be completed.

Some details on NP1 further below

Technical Features of the Aircraft
 The lcA will operate from an Aircraft
carrier with a concept of ski-jump Take
off but Arrested recovery (sTobAr).
Aircraft gets airborne over a ski jump in
about 200 m and lands 90 m using an
arrester hook engaging an arrester wire
on the ship.
 Derived from the Air Force version
it is a longitudinally unstable fly-bywire aircraft, making it an agile war
machine.
 Flight control system is augmented
with leading edge Vortex controller
(leVcoN) aiding reduction in approach
speed for carrier landing
 Auto throttle function reduces pilot
load by maintaining constant angle
of attack during the critical phase of a
flare-less carrier landing
 Fuel Dump system enables safe landing
by reducing weight in the event of an
emergency landing immediately after
launch from carrier

I think its more to do with image resolution...its been resized probably w/o keeping the original aspect ratio

Thank you all for clarifying that its Israeli Griffin and not DRDO Sudarshan. Especially the detailed difference by uddu.

I think its due to all the fat weapons it is carrying under its belly.

so, you mean 9 more months to delivery?

that is

. beating all 2014 expectations.

Looks like that centerline R-73 training round was test-fired and a video made.

I'd kill to get some shots of the LCA. All air-air were taken with a p&s

The first one with the harrier was with a D90 and it shows. Not bad.

centerline R-73? I've never seen a Tejas carrying a centerline R-73..there are 2 R-73s visible in the pic, both on hardpoint stations 5 & 6.

Indranil · Post by **Indranil** » 12 Jan 2012 06:27

Well I am surprised too ... I havn't seen a R-73 on any station other than 5 and 6. But this one looks like 5 and 7 for me. It looks too low and too far forward for being on station 6. Also the placement of the camera ...

NRao · Post by **NRao** » 12 Jan 2012 06:45

5, 6 & 7?

SaiK · Post by **SaiK** » 12 Jan 2012 07:08

The pilot's head AND shoulders can be seen above the fuselage-canopy interface. His view must be superlative.

The above aircraft has a radar ??

Yes! it has now,Elta/MMR Hybrid.

Craig Alpert · Post by **Craig Alpert** » 12 Jan 2012 08:01

and how exactly would you would know this by looking at the above pic? other than hearsay and publication ofcourse...

Prasad · Post by **Prasad** » 12 Jan 2012 08:08

Assumption based on the hazardous/rad symobl on the radome perhaps?

As per the Tejas page (and previous such weapons config images) the centerline hardpoint is not designed to carry an air-to-air missile. I'm pretty sure that its the angle of the aircraft that gives you the impression that station 7 is carrying the R-73.

Tejas weapons page

NRao, the numbers refer to the hardpoint stations as shown on the page above.

Radars don't have any external antennae.

Edit: I think you were talking about Pitot tubes. They are not antennae.

That may not say for sure that it has the MMR/2032 hybrid..This image from AI-2007 when it definitely didn't have a radar, only ballast, also had the radiation symbol.

nachiket · Post by **nachiket** » 12 Jan 2012 08:39

It depends on which prototype it is. If it is the LSP-5, it will have the radar.

Craig Alpert · Post by **Craig Alpert** » 12 Jan 2012 09:19

let's clear out some myths....
1) external antenna does not indicate that there is a radar present on board. Those could be EW related gear, or up/down links for data/video feed amongst other things.
2) hazardous/rad symbol indicates radioactivity, not indicative of radar on board.
3) the only way to physically tell that there is a radar on board is by being in the cockpit and turning on the screen to see what radar is on board, or if ground/maintenance crew pop open the radome to see what's under the hood.
I guess I was trying to get at how does one say that the above pic has xyz radar on board just by looking at the pic?

krishnan · Post by **krishnan** » 12 Jan 2012 09:21

Hmmm i always thought they indicated there was a radar

member_20067 · Post by **member_20067** » 12 Jan 2012 09:53

can someone throw some light on the top most harrier in the background.. its 2 seater however it looks like more chikna then the rest..

nachiket · Post by **nachiket** » 12 Jan 2012 09:56

^^That is a standard two-seat trainer version.
