    Sorry, but i fail to see the logic behind your question regarding Snecma and Rafale.

    so without Rafale engine license money and possible future upgradation market for next 40 years. why would Snecma help Kaveri which will be Indian product at the end.

    As for overdependence, if around 60% of IAF’s fleet (not to mention the better part of it) is composed of fighters from a single source, i would call it overdependence. Cosidering, India’s rising stature in world, increasing importance of military power to safeguard her intersts at home and abroad, deep desire to keep her policies independent, and ever changing geopolitical situation, i dont think India would want to be overdependent on any country in any way. Having said, here is an interesting thought. Both India and Russia have signed IPR agreement. Would joint ventures like Pak-FA/Mig-35 (if it happens) fall under IPR, i.e. wouldn’t India require Russian permission to upgrade them further from third sources?

    u can also add AWACS/Airtanker/transport/Ajt to ur overdependence category. and India is prefectly allowed to install third party systems on platforms provided it is with consultation with OEM. IPR is more related to sharing technology with third parties.

    another interesting point Kaveri RFP is only sent to Saturn and Snecma. why would Snecma help unless Rafale is chosen and there is big engine order. and overdependence question does not arise when u want 100% in house.

    IF they havent got end user certificate that late. it just show bad planning. and i doubt they have any engine to backup for the moment

    Russia did not block supply agreement to Pakistan of Chinese combat aircraft, but it insists on the observance of international law – Sergey Ivanov

    Bangalor. 23 January. INTERFAKS-AVN – Vice- premier – Minister of Defense RF Sergey Ivanov denied report, that Russia allegedly blocked supply agreement to Pakistan of Chinese combat aircraft.

    “Russia nothing blocks. This is not our policy “, he stated on Tuesday to journalists in Bangalore.

    At the same time S.Ivanov it noted that in a question of military technical collaboration Russia strictly soblyudayet international law. “I have in the form a certificate of the end user. RF achieves trade in weapon only with the presence of this certificate “, it emphasized S.Ivanov.

    Here is the problem. At a high altitude you really cannot image a moving ship, and by the time you do, you’re descending too fast. A higher speed means less time to do corrections, less time and opportunity for maneuver. Let’s also talk about what reentry speeds can do against conventional radomes.

    what speed u have in mind here.? I really gave example of light bulb. or insurgent in jungle.think about modern.

    As a rule, the killing device has to be faster than the target device, not the other way around

    Again self established rule. not surprizing.

    hmm, developing laser targeting systems is different from Anti-satellite laser weapon.

    how is that different? it is just difference in power to burn the panels of satellite. Soviet mastered this by early 80s. even today whole research is going on this.
    this from SDI montior

    U.S. intelligence assessments of the Soviet laser anti-satellite threat were based on the capabilities of several of these other lasers, one DOD official says. In 1987, U.S. Space Command chief Gen. John Piotrowski said Soviet lasers could cause structural damage to satellites at altitudes of 250-350 miles and damage solar panels in orbits as high as 1,700 miles
    While the U.S. may not have an accurate assessment of Soviet laser capability, “we know it exists and we have some idea of its scope. I believe it is a current threat and growing by the very vigorous research that they have going.”

    How is the engine above described looks like an RD-33?

    Design

    axial compressor
    WS-13 3 fan
    RD-93 4 fan

    secondary supercharging compressor
    WS-13 8 stage
    RD-33 9 stage

    Bypass Ratio
    WS-13 0.57
    RD-33 0.49

    Inlet temperature
    WS-13 1650c
    RD-33 1953c

    Pressure ratio
    WS-13 23
    RD-33 20

    Dimensions

    Diameter
    WS-13 1.02
    RD-33 1.04

    Dry weight
    WS-13 1135kg
    RD-33 1055kg

    Length
    WS-13 4144mm
    RD-33 4250mm

    Afterburner Thrust
    WS-13 8630kg
    RD-33 8300kg

    Dry Thrust
    WS-13 5675kg
    RD-33 5098kg

    from where this figures comes from? RD-133 has 5600KG thrust, 1145 kg weight. and 40 degree more temp. but not at 1930. It looks some one has superimposed those figures and created a speculation sheet.

    Still, a ground target is a non moving target. Ground speed is obvious; a complete zero. All it needs is a referential position. And yes, you can see the ground with electro-opticals (contrast imaging), IR imaging and SAR radar. Furthermore unlike in space, you can compensate with a proximity blast. In space, you cannot have proximity blast due to the lack of atmosphere. Shrapnel only damages satellites, which tend to be huge. Hence direct kinetic contact must be made to make a kill and blow it to smithereens.

    how is gound target a non moving? (infantry, tanks, mobile sam, artellery tracked through passive devices)
    the moment u lit up the SSM it already gives its trajectory with tracking radar. any modern SAM system can shoot it down. u need a Stealth missile in all spectrums with control flight and still able to hit a light bulb.

    Hitting something in the ground is definitely easier than hitting something in the air, much less in space at orbital speeds.

    orbital speeds are known. try hit the unknown speed.( which u cannot see with IR, Radio spectrums on ground). and on ground it is sharply reduced range and speed.

    so hitting some thing in air is the the same as hitting on the ground.
    key part of latest tactical SSM is unpredictable trajectory, stealth operations (engine turned off) and sharp maneouvers in terminal stage with vertical attack. It is not simply going from point A to Point B.

    No, they haven’t. Russia scraped its dozen or so IS-M anti-satellite missiles (based on SS-9) in 1993 because of their age. This system wasn’t replaced by “Contact” and “Naryad-V” due to lack of money. You know, Yeltsin bought only vodka at those days rejoicing US! 😀

    ever thought about there Laser system.

    http://www.fas.org/news/russia/1996/druma189_s96005.htm
    In those days I was preparing a detailed report for the Minister of Defense on means being used to track the Shuttle flight and on results of Outer Space Monitoring System operation. Then, some time in the autumn of 1983, Marshal of the Soviet Union D. Ustinov called me on the Kremlin phone [kremlevka]: I have before me your report on work on the Shuttle. Tell me, why hasn’t the experimental laser complex of General Designer Nikolay Ustinov been used?’ Dmitriy Fedorovich was excited over his son’s creation. At that time a team of 300 specialists was performing modifications on the complex, and I reported this to the Minister of Defense. And the experiment took place on 10 October 1984, during the Challenger’s 13th flight, when its orbital revolutions were passing in the vicinity of the National Air Defense Troops state range near Lake Balkhash, with the laser unit operating in a detection mode with minimum emissive power. The craft’s orbital altitude at that time was 365 km and the slant range of acquisition and tracking was 400-800 km. A precise target designation was issued to the laser unit by General Designer Grigoriy Kisunko’s Argun radar measurement complex.

    “The Challenger crew later reported that as they were flying over the vicinity of Balkhash, communications on the craft suddenly shut down, malfunctions appeared in operation of gear, and the astronauts themselves did not feel quite well. The Americans began to investigate and soon realized that the crew had been subjected to some kind of artificial effect from our side and lodged an official protest with the USSR. Based on humane considerations, the laser unit as well as a portion of the range’s radiotechnical complexes having a high energy potential subsequently were not employed to track the Shuttles.”

    The ASAT ‘stick.’ (military officers oppose antisatellite weapons), 1985
    The ASAT “Stick’

    One of the best-kept secrets in Washington is the military’s opposition to antisatellite weapons. Unfortunately, Congress has not been listening to what the generals and admirals are saying.

    One of the first to voice his reservations was Gen. Charles Gabriel, the Air Force Chief of Staff. In his testimony before the House Subcommittee on Defense Appropriations in March 1984, Gabriel said he favored a verifiable treaty banning ASATs. “Because we are an open society,’ he said, “we need our space capabilities more than the Soviets do.’ To understand this point fully, one must realize that current ASATs can destroy only low-altitude satellites. Should a race to develop them continue, however, the Soviet Union and the United States would surely achieve the capability to destroy high-altitude “birds.’ That would hurt the U.S. side far more than it would the Soviet because of America’s greater dependence on satellites for military command, control and communications. Also, “technical means’ (another term for satellites) enable U.S. intelligence to monitor the Soviet Union’s every military move, which includes tracking its nuclear missiles.

    Gabriel is not alone. In August of that year several admirals anonymously told The New York Times that they shared his reservations. The Navy relies on satellites for precise navigation and position-finding, which are crucial to the accuracy of Trident sea-launched missiles. And naval communications would be vulnerable to Soviet satellite destroyers, says Adm. Noel Gayler, retired, the only highranking Navy officer to speak for the record.
    The big push for ASAT tests has come from civilians in the Pentagon and in the White House. The Reaganites want a successful ASAT test before the November summit talks between Reagan and Soviet leader Mikhail Gorbachev so that the President won’t be forced to “negotiate from weakness.’ True, a single test–especially one that is three years behind schedule–does not prove the system is workable

    US deficit is no larger (in relative terms — % of its GDP) than UE’s and even smaller than Japan’s. Irak is another matter, it really sucks money. But if US air power is death, what about the rest of the world?

    It is not the size of deficit but Savings to finance Public/Private consumption that matters. so u have to accept cheap goods from China and not extend war on terror to house of saud.

    Thing is that ally thing is meant to work both ways. In other words, i think Russia would block the sale only if India is willing to give them MMRCA deal.

    these decisions are not based on single contract but overall beneficial relations like upcoming diesel submarine contract IN etc.

    some thing about T/R module origin for MIG-35

    A.Kanashchenkov has informed, that elements of a radar with АФАР are created in cooperation with the several enterprises. « The technology — three firms participating in the project is now fulfilled , have organized coproduction which is modernized so that on its(his) base to form a ruler of creation of modules », — A.Kanashchenkov has told.

    As he said, manufacture is created on the basis of Tomsk institute ” МИКРАН ” at which there is large enough manufacture making a modern communication facility. According to A.Kanashchenkova, one firm involved in cooperation, specializes in the field of semi-conductor technology, and another has manufacturing techniques of monolithic elements in structure of the receiving-transferring module.

    « Corporation ” Phasotron-¡¿¿Ó ” defines(determines) ideology of leaded and perspective works », — A.Kanashchenkov has told.
