These upgrades will keep the plane worthy for next 10 - 15 years till AMCA comes and will stop IAF from loosing more squadrons.

I have lot of praises for "Chanakya" from the stories read about him, may be HAL should take few notes out of them and think twice before undertaking the task of upgrading such older platforms with the technologies gained during development of tejas to the reluctant IAF who most likely will have huge cry over the upgraded 3 generation planes without understanding the limitations inherent in design and will benefit maximum for next 10 years with reasonable amount of doubt associated. Needless to say that no other country/organisation will support such upgrades if refused by HAL and may ultimately open eyes of IAF to move to better platform and technology at present available in India save wasteful money and help in further development of complex technologies without which even these upgrades were not possible.

Honeywell engines happening or not?

Since it will more power and save fuel..

Its a extra expenditure but Jaguar Will be efficient in doing its role,

First retire mig 27 and 21, replace it with mmrca & tejas, that itself will take a decade..

Next jaguar with amca or fgfa

Indian Air Force Confirms Jaguar Re-engine Plan


The Indian Air Force (IAF) has confirmed that it will re-engine its fleet of Anglo-French Jaguar strike aircraft. The plan was discussed by IAF Chief of Air Staff Arup Raha during his annual press conference this week. Raha was enthusiastic about the recently confirmed acquisition of Dassault Rafales, but cautious on progress with the Fifth Generation Fighter Aircraft (FGFA) project with Russia.

“Technology is improving so rapidly that weapon systems and platforms soon become redundant,” said Raha. This phenomenon is being addressed through the IAF’s Long Term Perspective Plan, a 15-year scheme that is divided into three five-year spans. Raha said that while most previous procurement “had been process-driven; it is now changing to outcome-driven.”

Honeywell is to supply 270 F125IN turbofan engines to replace the twin Rolls-Royce Adour Mk 821s on apporoximately 120 Jaguars. The F125 is 600 pounds lighter and should enable 25-percent-shorter hot-and-high takeoffs. Raha said India’s Jaguars have become overweight and underpowered because of avionics and systems upgrades. Honeywell will first be required to conduct a trial modification of the Jaguars with the new engines. The plan was first mooted in 2012.

Full of praise for the Rafale, for which the IAF has signed a contract for 36, Raha added: “We’d like more, but the decision has to be taken in the near future based on capability and price.” Other officials in the IAF told AIN that the version for India would be more lethal than the French and other recent international versions.

An Inter-Governmental Agreement was signed for co-production of the FGFA. But now that the IAF has completed a design review, it has “found gaps in information in terms of the depth and transfer of technology…and a lack of visibility of total cost,” said Raha. While things are now clearer, “let us see what happens,” he added.

The IAF combat fighter inventory includes 270 Su-30MKIs. An official said: “Ordering more will not be wise. We should not have all our eggs in one basket.”

Live firing of the air-to-ground version of the Brahmos missile on the modified Sukhoi Su-30 MKI will be finished in three months.

Aiming to boost its capability for local production via a transfer of technology, India has received “unsolicited offers for the Gripen, F-16, and F-18. Whoever gives the best deal will get the contract,” said Raha. Meanwhile, deliveries of the 80 indigenous Light Combat Aircraft (LCA) Mk1 version will not be completed until 2028.

IAF Jaguar Aircraft To Be Equipped With Modern AESA Radars



Indian Air Force will upgrade its 120 Jaguar aircraft with Advanced Electronically Scanned Array (AESA) radar and new Honeywell F-125N engines.

During his customary annual press conference ahead of the Air Force Day on October 8, the IAF Chief of Air Staff Arup Raha said: “The air force has plans to re-engine its fleet of Anglo-French Jaguar strike aircraft”.

The aircraft will also be equipped with indigenous DARIN-3 navigation-attack systems and the smart CBU-105 “sensor fuzed weapons” that India bought from Textron, USA, Raha said.

Honeywell will be supplying 270 F125IN turbofan engines to replace the twin Rolls-Royce Adour Mk 821s on 120 Jaguars.

The F125 is 600 pounds lighter and should enable 25-percent-shorter hot-and-high takeoffs. India’s Jaguars have become overweight and underpowered because of avionics and systems upgrades, Raha said.

It is aburd to spend US$ 40 million to upgrade 30 year platform worth US$ 15 million. At cost of Single upgrade we can buy 2 LCA. Which is better? Single upgraded 30 year old aircraft based on 50 year old design which will serve for another 10 years or 2 LCA for same price which will serve for 40 years?

Two very different platforms with very different roles and capabilities. One is an interceptor fighter, other is a deep penetration strike aircraft.

I'm no expert. Is it possible to use the Kaveri engine in the Jaguars? Given that the Jaguar doesn't need a super high power engine in the 100kn+ class, the 80kn(?) of the Kaveri should work for the Jag.

I don't know if there are other issues like size, fitment etc. In any case the F125 can't be a direct replacement of the RR engines - some modifications got to be done. So why not use the Kaveri?

120+ Kaveri engine order plus spares and follow ons would be a fantastic kickstart for the Kaveri program.

Kaveri isn't a matured engine.
There are issues persisting with it particularly when it's taken to max thrust and then into reheat.
Last I heard, SNECMA was roped in to help resolve the issues with it but I don't know how far that got.

Kaveri cannot be fitted in Jaguar. They are of different class. Kaveri can be fitted in a Medium weight aircraft as one of its two engines. If a bigger version of LCA is ever built (bigger than Mk2), Kaveri could be used there. Or it could be used in our UAVs. It cannot be used in Jaguar.

Can you explain more - why it cannot be fitted?

Specification (GTX-35VS Kaveri)[edit]
General characteristics
  • Type: afterburning turbofan
  • Length: 137.4 in (3490 mm)
  • Diameter: 35.8 in (910 mm)
  • Dry weight: 2,724 lb (1,235 kg) [Goal: 2,100-2450 lb (950-1100 kg)]
Specifications (F124-GA-100)[edit]
Data from [12][15]

General characteristics
  • Type: Turbofan
  • Length: 102.1 in (259 cm)
  • Diameter: 37.6 in (95.5 cm)
  • Dry weight: 1050 lb (521.6 kg)
Can you explain more - why it cannot be fitted?

well how do we fit in the length or diameter & the dry weight ..... even the CG will change

if u think that just the dry kaveri can replace both engines just because the thrust is better then the CG & the flight rules of jags will change ................ to do so they need all types of tests running into years

& cost may be more than F 125 purchase.

not anymore, that's why they invented a term call multirole, I agree Jag can perform a deep penetration mission better, but you have to calculate cost vs capability. LCA flight control should be good enough.

Because of different dimensions, different thrust, different bypass ratio, everything about the engine is different as compared to the honeywell engine.
And what about HTFE-25 ?? Its similar to honeywell.

It is indeed strange that they plan to have an AESA for Jagaurr, but IAF does not deem it important for a "frontline" fighter like Mirage 2000 to have an AESA?

Most planes that would be in service till say 2030 seems are expected to have an AESA with only exception being the Mirage 2000. Even with Super sukhoi upgrade, there is plan to have an AESA for Su-30 MKI.
What logic is that? By the way, the Israelis have an AESA radar for Mirage 2000..
Maybe perhaps if they had put the AESA the price (due to high commission) might look like the cost of upgrade of one Mirage 2000 is almost twice the price of new Su-30 MKI..
Maybe thats why the AESA was overlooked? Wonder what the ACM has to say

After wasting so much money on the Mirage going the French route for it's upgrade, they have nothing left for the Mirage, it's a pity, Israeli plan for IAF Mirage upgrade was cheaper and also had AESA, Python-5 and other cool goodies in it.

No body has more options than OEM. Upgrade with RDY2 and MICA will bring it to on par with what the French themselves are flying.

Who cares what the French are flying, we missed out on an opportunity to turn the Mirage into a 4.5 gen aircraft and squandered millions down the drain
