    The only engine that would meet that criteria as of now is RD-33MKM with about 93KN thrust and 3D-TVC.

    Snecma with 90KN engine is atleast 5 years away if French finds someone to finance it. TVC and Snecma, unlikely…. Eurojet is atleast 5 years away from fielding an operational TVC engine, which is suppose to happen in 2018. In short the first production standard TVC engine from the western side is atleast 13 years behind RD-33.

    Not necessary, if they do not insist on TV in the first couple of prototypes they have plenty of options. From what a chaiwallah told me last year, the current Kaveri was supposed to be flown with Tejas in late 2013 (the current schedule cannot be confirmed). AURA is supposed to fly with that same basic engine as well, so they can use the basic Kaveri for first couple of prototypes and switch to the Snecma-Kaveri when it is ready. They can also go in got GE-414IN56 (the deal we signed has an option of far higher numbers of engines than what is currently needed) as the Kaveri has been modified to be a direct fit in GE-414 engine bay.

    Those modifications dont seem to be accurate. For example, I am pretty sure they will not be adding in a FBW system to the Jaguar.

    Everything except the fbw has been confirmed by one news source or the other. This image was first published in the daily fail, so I doubt if they will be willing to dig up Jaguar ACT program.

    About auto pilot, from the release on press information bureau:

    Auto Pilot System for Jaguar Aircraft (03-Sep-2012:03:25:32)
    Integration of autopilot on Jaguar aircraft of the Indian Air Force is being undertaken in two phases. Procurement of autopilot for 55 Jaguar aircraft has been completed and commercial discussions for repeat procurement of additional 95 autopilots are under progress.

    This information was given by Minister of Defence Shri AK Antony in a written reply to Shri BN Prasad Mahatoin Lok Sabha today.

    About avionics upgrade and IDAS:-
    http://www.acig.info/CMS/index.php?option=com_content&task=view&id=253&Itemid=47

    The so-called ‘D-3 Jaguar IS’ are featuring the same HUD as on LCA ‘Tejas’, along with three MFD-55 AMLCDs supplied by THALES-Samtel Display Systems and full HOTAS controls, all utilising a MIL-STD-1553B digital databus. The core avionics computer – reportedly the same as in the MiG-27UPG upgrade at HAL-Nasik – is the OSAMC (Open Systems Architecture Mission Computer) originally developed by DARE and now produced by an India-US joint venture involving HAL, ‘Edge Tech India’ and US-based ‘Edgewood Ventures LLC’. An integrated defensive aids suite (IDAS) is coming from DRDO and Cassidian, including the D-3’s to be equipped with RAFAEL Litening-3SU laser designation pods for all-weather standoff-attacks using precision-guided munitions. Undecided in DARIN-III are the EW escort-jammers/towed-decoy systems, with offers from Raytheon (ALQ-184(V)9), BAE-Systems (ALE-55), IAI/ELTA (EL/L-8251) and RAFAEL (‘Sky Shield’ escort-jammer / ‘X-Guard’). The fibre-optic towed-*decoy is to produce a full range of noise- and deception-signals be*tween 4.5GHz and 18GHz.

    Raytheon Begins Procuring Parts for India’s Munitions Control Unit
    MCU will enable Indian Air Force Jaguar aircraft to employ modern precision weapons
    NEW DELHI, March 29, 2012 /PRNewswire/ — Raytheon Company (NYSE: RTN) has started procuring components required to build the Munitions Control Units for 126 of the Indian Air Force’s Jaguar Darin II attack aircraft.

    The MCU enables integration of modern weapons on legacy aircraft with minimal to no modifications to aircraft wiring and the flight or stores management software. The MCU’s compact size enables it to be located in a weapons pylon or avionics bay of a legacy aircraft. From there, it interfaces between “smart” weapons and the existing software of a legacy aircraft.

    “Providing the IAF the capability to enhance their Jaguar fleet is the latest chapter in Raytheon’s six-decade history of trusted partnership in India,” said Harry Schulte, Raytheon Missile Systems’ vice president of Air Warfare Systems. “MCU will give the Jaguar the capability to employ ‘smart’ or ‘advanced’ weapons like the Joint Standoff Weapon, Maverick missile, Paveway™ precision-guided munition and AIM-9M Sidewinder air-to-air missile.”

    Raytheon was awarded a contract to build the MCU in 2011, and funding was authorized for the system in 2012. In anticipation of the contract, Raytheon began preliminary work to integrate MCU on Jaguar in 2008.

    About the Munitions Control Unit

    Dimensions: approximately 13 by 6 by 3 inches and weighs roughly 6 pounds.
    Enables integration of modern weapons on legacy aircraft.
    Requires minimal modifications to aircraft wiring and no changes to the flight or stores management software.

    What ASR does IAF currently have for AMCA? I have seen reports of an AMCA design weighing ~15 tonnes, another ~20 tonnes and ASR being for a ~25 tonne aircraft. 25 tonnes is not possible with proposed Kaveri, is it?

    The last credible report had this to say:-

    With aerodynamic design optimisation near complete, the AMCA’s broad specifications are final. The aicraft will have a weight of 16-18 tonnes [16-18 tons with 2-tons of internal weapons and four-tonnes of internal fuel with a combat ceiling of 15-km, max speed of 1.8-Mach at 11-km. The AMCA will be powered by 2 x 90KN engines with vectored nozzles—likely to be the new GTRE-Snecma engine under development.

    It will be closer to MiG-29 in size than F-35.

    is the airplane too small to be effective?

    Strictly in my opinion, yes. The small aircraft will always have to compromise between range and payload. That is why small fighters work well for smaller nations.

    is HAL incapable of meeting targets?

    Perfectly capable of doing so. They productionised Dhruv, they have license made and maintained almost a dozen aircraft types of different pedigree. If that doesn’t make the organisation capable of productionising the Tejas then nothing in the world can. HAL will have to take the last step of making the transition from an apprentice to a stand alone practitioner.

    You are missing the big picture Pioneer. There is a difference between “Nationalist drunkenness” and making a product which was going to get hit by sanctions sooner or later. You can question the wisdom of the decision, but as far as subsystems are concerned, they eventually got most of them right, but on the whole, the whole project got shafted.

    Hi Guys

    At what stage is MMRCA contract? Was away and haven’t kept in touch with the news. Cant find any latest news regarding it.

    Last heard:-

    […]They also said that discussions with the French manufacturer Dassault for finalising the contract for 126 Rafale medium multi-role combat aircraft (MMRCA) were being held on almost a daily basis and the contract should be finalised and signed by the end of fiscal 2012-13, that is by March 2013.

    Came across the Honeywell presentation for Jaguar upgrade. Wow, that is some serious capability boost !!

    -236kg reduction in empty weight.
    -2000kg gain in payload.
    -23%reduction in take off distance in hot and high conditions
    -faster climb rates to 6000m altitude
    -36% extension in range
    -engine capable of auto restart
    -plenty of factors easing maintenance (the video features a clip of engine change)

    Couple it with the modifications covered here and its a whole new bird.

    Jaguar re-engining crawls another inch.

    http://timesofindia.indiatimes.com/india/Jaguars-to-get-more-teeth-muscle/articleshow/16841609.cms?

    NEW DELHI: India is finally giving its Jaguar “strike” fighters some much-needed new teeth with advanced missiles, engines and avionics. Apart from having a maritime strike role as well, the Jaguars have long been identified by IAF as the jets capable of delivering nuclear weapons if required.

    The IAF on Monday issued a RFP (request for proposal) to M/s Honeywell Aerospace, the US-based manufacturer of aircraft engines and avionics, to “completely re-engine” 125 Jaguars and provide 270 F-125IN turbofan engines.

    Concurrently, IAF is all set for the first test-flight of a Jagaur fighter upgraded to “Darin-III” standards by defence PSU Hindustan Aeronautics (HAL), with new-generation avionics including a glass cockpit and autopilot, next month.

    PANAJI, October 15, 2012
    Three naval personnel killed in chopper crash

    Three naval personnel, including two officers, were on Monday killed when their Chetak helicopter crashed while landing at Dabolim naval base here.

    “All three personnel on board have died in the crash which took place at about 1000 hours. A board of inquiry has been ordered to ascertain the causes behind it,” a Navy spokesperson said in Delhi.

    The chopper, which was flying from Mumbai to Bangalore, was making a scheduled refuelling halt at ‘INS Hansa’ naval air base here, he said.

    The rotor of the helicopter broke while landing, Navy sources said here, adding that the chopper then caught fire.

    Seems like the Army is trying to fit a GMTI radar to Dhruv.

    In a first that will give a major boost to the Army’s aviation wing, India is planning to procure helicopter-borne early warning systems for the land force. The final specifications for the system are being chalked out, following which a tender process will be initiated this year.

    The new system could be fitted on board the Army’s existing Advanced Light Helicopters (ALH) and will give formation commanders an insight into enemy territory while serving as warning systems for approaching aircraft and armoured units.

    yes,Apache going to army now
    :dev2:

    A denial has come out as well:
    http://economictimes.indiatimes.com/news/politics/nation/government-rebuffs-iaf-gives-army-attack-choppers/articleshow/16793296.cms

    MoD sources, however, said the “ongoing” procurement process for acquisition of 22 AH-64D Apache Longbow attack helicopters, with a weapons package including hundreds of Hellfire and Stinger missiles from the US in an $1.4 billion deal, will be for IAF.

    “The Army will get ‘future’ acquisitions. It will have to come up with its own concrete plans for induction of attack helicopters, with all their infrastructure, maintenance and training matters,” said a source.

    I can see army taking its pound of flesh from the repeat order quota if IAF doesn’t.
