    GE is apparently the largest foreign employer in india with a staff of around 20000 engaged in everything from back office processing to Phd level research via many divisions. they have a gigantic R&D laboratory in whitefield near bangalore employing 1000+ Phds/MS

    in europe I think germany and italy could do a 4+ gen alone if they were pushed to it. who else other than UK and france?

    uk, france are ofcourse in the A-list. sweden doesnt have a engine but has the rest in place, they could develop a engine if need be.

    the biggest economies tend to have the deepest depth of capabilities. so its no surprise germany , uk, france and italy are the top economies of europe.

    can this detached bow shock damage the engine physically or it just reduces the thrust ? perhaps someone with knowledge can explain…

    I did a blind search for “jet engine collapse” in google and came up
    with two interesting cases:

    air inlet physical collapse
    http://tanks45.tripod.com/Jets45/Histories/Guardian/Guardian.htm

    and collapse of shock waves inside the engine (this could be the one!)
    http://www.mtu.de/channel/files/pdf/26869vki_kreiner_lietzau_intranet.pdf

    “in supersonic or hypersonic flight regimes the matching between
    the air intake and the engine itself is of vital importance. if this
    matching is insufficient, the system of oblique and normal shocks
    outside and inside the inlet can collapse. this can lead to detached
    bow shock inside the inlet, having severe consequences on the absolute value of net thrust but above all in the direction of the
    net thrust vector angle. ” [ Page 9 of the file ]

    I am sure GE reps are already burning the phone lines 🙂 but IAF has to sign off on accepting a few sqdns or perhaps all its LCA with a american engine. they have to decide now rather than raise objections later.

    detailed news on the kaveri has been hard to come by. I somewhat doubt the details you ask for will be made public. it is true like you posted that kaveri has undergone some ground tests and airborne tests in Gromov instt. but that was a work in progress not final trials of a finished product.

    Erez is also right. the fruits of the Lavi experience are visible today in Israel’s mastery many aerospace fields.

    Ken, the US fighters mostly likely do use some computer components manufactured in the far east. I think only Russia makes stuff that is 100% local down to the last bolt and even there certain things may be sourced from east european nations. they have also started to use western components like texas instruments DSP chips these days.
    so this 100% indigenous “bar” is a sham esp. for the IAF which uses foreign radars and missiles on all existing ac.

    GE anticipating problems with the Kaveri has already made an offer to uprate the present engine with technology from the Gripen RM12 engine as a suitable definitive engine for the LCA.

    IAF is already using all foreign missiles on ALL its a/c so lack of a domestic missile on the LCA is a non-issue.

    So since relations with the US are expected to be quite cordial going fwd, they can simply build more than the planned number of LCA’s with the GE engines.

    Obviously there will be hecklers in the media and here(!) but who
    cares? someone above was right that nobody is going to share
    design data for engines, so the Kaveri must also be kept funded and continue until it delivers a product….late though it will be.

    The F404-GE-IN20 engine for the limited series production aircraft will be a variant of the F404-GE-402, modified to power the single-engine LCA with redundant features and a control system with an advanced FADEC (full authority digital electronic control).

    India ; US to send nuke submarine for exercise with India
    29-September-2004

    India News, New Delhi, For the second consecutive year the US is sending a nuclear-powered submarine for a major naval exercise with India to be conducted in the Arabian Sea.

    Exercise Malabar 04, to be held off the Konkan coast in early October, will see seven frontline warships and submarines of the Indian and US navies practising advanced anti-submarine warfare and anti-terrorism operations.

    “In order to streamline interoperability and derive maximum training value for such exercises, the two navies have also evolved standard operating procedures, which would be tested during the exercise,” said Indian Navy spokesman Commander Vinay Garg.

    This is the sixth in the Malabar series of manoeuvres since 1992 and the third such war game held by the two navies since India and the US resumed defence ties after the 1998 nuclear tests by New Delhi.

    all the good ones have a CEP of < 100m. this is deemed ok for nuclear payloads which is what most of them are meant to carry.

    PTI news:

    India, Singapore joint naval exercise in south China sea
    Sept 28, 2004 05:45:00 PM

    .NEWDEL DEL38

    New Delhi, Sept 28 (PTI) Indian Naval warships would make foray into the south China sea as they hold joint manoeuvers with the Singapore Navy in mid 2005.
    Frontline Indian warships, including the just-acquired stealth frigates from Russia, would join in the week-long exercises with Singapore Navy’s sophisticated anti-submarine warships, according to naval sources here.

    Though India and China held some exercises off the Shangai port last year, this would be first time that Indian Warships would be involved in manoeuvres in the South China sea.

    India and Singapore have been holding joint exercises for the past 11 years, but these have been in Indian waters and this time, visiting Singapore Naval Chief Rear Admiral Ronnie Tay invited Indian Naval warships to undertake joint manoeuvres in the south China sea.

    Tay, on a three day visit here, held discussions with his Indian counterpart Admiral Arun Prakash. He also met the Army Chief Gen NC Vij and Vice Chief of the Air Staff. The Singapore Naval Chief will also visit Western Naval Command headquarters and warships in Mumbai.

    The two countries also touched upon possibilities of Indian Naval warships undertaking joint patrolling of the strategic Malacca Straits. The visit of the Singapore Naval Chief comes on the heels of the discussions held by the Malaysian Naval Chief here last month during which revival of Joint patrolling of the Malacca Straits had also figured.

    The scope of the Indo-Singapore exercises, a naval spokesman said had widened with the acquisition of submarines by the Singapore Navy recently. PTI

    given the lack of railroads in a vast area of western china (the qinghai-lhasa line is going to be the first?) I agree with Douglas M that something to life MBT is much needed to deploy RRF into sinkiang and tibet atleast.

    for other places, railway offers a efficient soln – entire regiment can be shipped in one go.

    I believe some co in China spent about $700 mil buying up a design and complete rights from Dornier. China wants to make a big push and I dont think they will be shy of spending the big bucks. Perhaps a JV based in china will do the final assembly while ukraine and russia will supply key subsystems , engines etc to recover profits…same as Flanker deals.
