    A question to what they know:
    Why frigates produced after the fall of the Soviet Union (Talwar) are based on the modernization of project 1135 and non of the most new project 11540?
    Thanks

    Argentine Mirage IIIEA and Daguer did not had RWR.
    In a very controversial decision, MIIIEA was incorporated as interceptors without much of the electronic original (lack of vision and perhaps money)

    Check this book:

    The only figures I have are for the Air Force.

    According to Jane’s, six C-130H have survived from a batch of seven. Five are to be upgraded with glass cockpits, FLIR, a ground proximity management system and GPS, under a FAdeA contract worth a reported $166 million.

    You seem to be right about the L-100-30 Hercules – one is in AF service.

    There are also two KC-130H delivered in 1979.

    Only the air force has Hercules in Argentina.

    in theory:

    1 C130E upgrated to H
    5 C130H
    2 C130B
    2 KC130H
    1 L-100

    not everyone is in good condition. 🙁

    My cousin there told me some bizarre stories. There are money in Argentine but the government is deliberately forcing the starving of the armed forces. Food producers must pay a special exportation tax whose revenues are channelized to give gifts to unskilled undereducated people. This in turn create a big inflow of undereducated unskilled people form Andes countries to regions formerly populated by whites, thus creating ethnical tensions. That’s seems really weird.
    And some politicians claim that is good to terminate with the Army. So, to buy new fighters is the last priority.

    political exaggerations.

    To be realistic, according to what the actual Argentine government is spending on military, we should be discussing if the Nieuport Bleriot XI is better than the Caudron G.IV. Maybe it could be possible to adapt AIM-9L and LGB to them.
    The true is that by now the Argentine Air Force is analyzing some options, but they don’t have budget. For the budget sent to the congress for 2012, there are no plans to buy any combat aircraft, they only talk about buying spares for the A-4ARs. I don’t think something is going to happen on this topic until 2016, when possibly and hopefully, a new government can arrive.
    Nobody knows what is going to happen with the Grupo 6 de Caza, as their Mirages are ending their career, with only a handfull of them flying, and no replacement is expected in the short term.

    Best regards

    A statement pessimistic but not far from the reality of our country. Anyway I think that “something” can be purchased in a couple of years.But will not be modern, new, Chinese or Russian.

    Some Su-25SM modernization numbers : 8 in 2011, 16 in 2012, and 12 in 2013. Prior to 2011 the RuAF received 43 Su-25SM.

    my numbers:

    2006 6 modifications ( given to the VVS in public act in December of 2006)
    2007 6 modifications (annual balance of the plant of repair airships 121º)
    2008 8 modifications (annual balance of the plant of repair airships 121º)
    2009 13 modifications (annual balance of the plant of repair airships 121º)
    2010 12 modifications

    Single crystal tech has been there for a while. It was even transferred to India as a part of AL-31f ToT for the Mki engine plant at Koraput.

    that I have listened but never I saw no good source or technical details. you know which alloy is used in the blades of Al-31FP?

    I guess that monocrystal blades were used for the first time on AL-41 engine, so I guess that USSR/Russia posses the technology since the 80s.

    surely they will have the basic technology, but besides the new PS-90A2, Which other engine produced in series uses it?

    It is likely single crystal or maybe even CMC. Single crystal blades are nothing new.

    Not in the west, but which Soviet/Russian engine use that technology?

    it is known which type of technology is used to make the blades of the turbine of “117S” or Al-31FM2 “Directional hardening” or single crystal? The alloys?

    Al-31FP is from Saturn and UMPO, not Salut

    some sourse about AL-31fm2 and 117S,I hope that it is reliable

    I think that Al-31FM2 is the Salut equivalent of 117S
