    Ahem..I cant quite see whats all the arguing about.Swerve put it very nicely.

    Apart from learning to handle such kind of ships,mil use and also humanitarian use..I am guessing that it will be a lot of help in building those.IIRC there is plans to build 3 LPDs.Dunno whats their status though.

    I don’t know if India has any Amphibious AFV?

    Look here..(scroll down to the Amphibious vessels)
    http://www.bharat-rakshak.com/NAVY/Surface.html

    The Saipan I think is a great ship..but with the Harriers at the en of their lifetime I dont think the full capabilities of the Saipan can be exploited.

    Is there extensive hospital with operating rooms and hundreds of beds

    It has a large hospital?

    Ankush,
    You are ignoring the fact that LRAAM developments are not happening in the world in total vaccum. Jamming and other counter measures will also get better at the same rate and i don’t see how a much bigger platform with more freedom of space than your smaller LRAAM could not be improved to counter such threats.

    The first shot advanatge is not a zero sum game , or is it?

    Hmm..lets go back to the fifties..and think that an R-77 or an Amraam couldnt possibly be effective because countermeasures will be developed and also long range..more freedom of movement right?:diablo:

    These videos here show missiles hitting targets during their powered stages.

    Most A2A missile intercepts occur within 10 to 30 seconds.

    If you want to video them(as in some trials) you have to place targets very near the launching platform.That is hardly possible in actual BVR fights which occur say around 40-50 kms or more.And those trials which are done for longer ranges..you hardly see any videos of those.

    10 secs maybe correct for WVR engagements.But then again,most of the missiles have powered stages less than 10s.For eg.Astra having design maximum range for fighter a/c of 80kms have solid propellant motor with burn time of only 5.4 s,Aim7E had a burn time of 2.8s and a range of 35kms.Now it can be calculated approximately that during those periods they donot cover anywhere near their intended distances.
    SAMs though acting on similar principles are also very different.More no. of stages,more burntimes.So in that case many of them might intercept during powered stage…more so if the a/c is flying at not very high alt(also can be video’d).

    Anyway coming to the actual issue,ramjet misiles have lots of advantages over rocket powered ones…Meteor is going to be one mean customer.Dunno what happened to the ramjet R77..

    Wasnt MMR scheduled to be integrated onto LSP 3? (the one close to the IOC std). Only 2-3 sets of 2032 have been purchased.

    I am not sure..I think I read somewhere that 2032 is going into it.

    imo MMR may find a role in HALs upcoming CAT AJT which will supplement the
    Hawk. IAF will need a AESA is a fighter serving after 2010 and that is called EL-2052. the 2032 maybe a convenient stepping stone into final configuration.

    its very hard for a new unproven radar to match across the spectrum a mature
    and proven soln like APG68-v9 that America has arranged to supply on F-16.

    I totally agree.

    Not really. Why do you think missiles are often fired well within their stated ballistic ranges? Or fired in near WVR ranges? Or fired in dogfight modes even in WVR?

    In general a2a missiles have short burntimes and that is aimed at getting the missile to a state of high KE+PE and to the fly-out point(i.e.range),after that the manouevre(and that includes terminal stages when most of the manouevre is required) is mainly passive with the help of the control surfaces..mainly because the total KE+PE gained by the missile is sufficient to carry it to the calculated interception point.
    Not only a2a missiles,the SAMs also work on the same principle.

    That is reflected by the missile burntimes which are in the order of just a fewsecs(<10)…where as the time of flight is more like a minute or a bit more.

    There are many reasons why missiles are not fired at their extreme ballistic ranges.Number one is that you have to reliably calculate the fly-out point of the missile from the radar returns so as to have maximum chances of interception.And also to disallow the opponent enough time to change the interception point by a large extent thereby again increasing the chances of interception.That however doesnt mean that you are firing at close range so that interception always occurs during the powered flight.

    Are the Indians gonna hurry-up with their MMRCA RFP, now that N-talks with Washington have broken down?

    What?

    This is from today..

    The problem I see with ramjet missiles is that they don’t maneuver very well. Their thrust is dependent on the speed of the air going into the intake. When you maneuver, that speed is lost due to the loss of the ram effect through the intake. Ramjet missiles, while they will have great range, will not have the maneuverbility of rocket propelled missiles.

    In rocket propelled missiles,generally the motor has already burned off before terminal manouevre starts..so I dont see where the problem is.

    😀 he was giving an example, please PM him on other topics or open another thread, this isnt a thread for LCA or the JF17 for that matter

    Why dont you pm him first and ask not to cite bogus examples?:D

    Yet they are unable to make even a light fighter aircraft with sufficient performance to gain trust from their own air force.

    Cant discuss without flamebaiting can you?:rolleyes:

    1.Tejas has full backing of the airforce.IAF has expressed intent to acquire at least 40 aircrafts.
    2.5 prototypes+1 LSP with already 672 flights already completed hardly qualifies as “unable to make”.
    3.Performance wise except for having slightly less range,Tejas excels the JF-17 in all parameters.So if the PAF can accept the JF-17,why cant the IAF accept the LCA?

    :rolleyes:

    I thought the C130 and the AN32 were in the same lift class. Is there that significant a difference between the russian and US plane to warrant a billion dollar spend on 6 planes? What am i missing here?

    An-32 MTOW is 27000kgs where as C-130J MTOW is 70300 kgs that seems like a considerable difference.And yes the An-32s are becoming old and they have to be replaced if not today,then tomorrow.

    OTOH Il-76 MD has MTOW of 170000kgs and the HAL-Irkut MTA closely matches the C-130 with MTOW of 68000 kgs(acc to HAL infoboard)/55000 kgs( acc to Irkut site).

    As has been said those will be used for special operations(required now)..and in future the role of An-32(India) and An-12(Russia)will be finally taken by the MTA…/which begins to come in the 2015-2020 timeframe.

    Here is an article on the MTA development if anyones interested:Link

    I thought this was over and done with..but again a flurry of reports :

    India clinches $1b Hercules deal
    31 May, 2007 l 0132 hrs ISTlChidanand Rajghatta/TIMES NEWS NETWORK
    WASHINGTON: The Bush administration has notified Congress of the impending sale to India of six C-130J aircraft and accessories worth more than $1 billion, underscoring the growing “Americanisation” of Indian military hardware.

    The proposed sale, the Defence Security Cooperation Agency (DSCA) said in its notification this week, “will enhance the foreign policy and national security objectives of the US by providing the Indian government with a credible special operations airlift capacity that will deter aggression in the region, provide humanitarian airlift capability and provide interoperability with US forces in coalition operations.”

    The purchase will mark a significant diversification of India’s military transport paradigm that has traditionally rested on Soviet-supplied AN-32 and IL-76 aircraft. Earlier this year, New Delhi purchased the American landing dock USS Trenton, which will give the Indian Navy amphibious landing capability.

    The $1.059 billion transaction will also be the single largest Indian military purchase to date from the United States. C-130J is the latest model of the trusted and versatile Hercules transport aircraft that has been an American workhorse for half a century, the longest continuous production-run of any military aircraft in history.

    Capable of short takeoffs and landings from unprepared runways and dirt tracks, the C-130 was originally designed as a troop, medical evacuation and cargo transport aircraft.

    But the latest model that India will purchase will be a souped up version of the Super Hercules, capable of multiple functions. Much of the special mission equipment added to the Hercules is removable, allowing the aircraft to revert back to its cargo delivery role if desired. The C-130J is currently being used by American and allied forces in Iraq and Afghanistan.

    In addition to the basic aircraft frames and equipment, India is also said to have asked for four Rolls Royce AE 2100D3 spare engines; eight AAR-47 Missile Warning Systems; eight AN/ALR-56M Advanced Radar Warning Receivers; eight AN/ALE-47 Counter-Measures Dispensing Systems; eight AAQ-22 Star SAFIRE III Special Operations Suites.

    Also the same news from DID..about the stuff India requested …

    May 25/07: The US Defense Security Cooperation Agency notifies Congress [PDF format] of India’s request for 6 C-130J Aircraft in Special Forces configuration, as well as associated equipment and services. The total value if all options are exercised, could be as high as $1.059 billion, and the request includes:

    6 Lockheed Martin C-130J United States Air Force (USAF) baseline aircraft including USAF baseline equipment
    4 Rolls Royce AE 2100D3 spare engines
    8 AAR-47 Missile Warning Systems (two of them spares)
    8 AN/ALR-56M Advanced Radar Warning Receivers (two of them spares)
    8 AN/ALE-47 Counter-Measures Dispensing Systems (two of them spares)
    8 AAQ-22 Star SAFIRE III Special Operations Suites (two of them spares)
    8 ALQ-211 Suite of Integrated Radio Frequency Countermeasures (two of them spares)
    2 spare AN/ARC-210 Single Channel Ground and Airborne Radio Systems (SINCGARS)
    8 spare Secure Voice Very High Frequency/Ultra High Frequency Radios
    4 spare Secure Voice High Frequency Radios
    3 spare AN/AAR-222 SINCGARS and Key Gen (KV-10) Systems
    1 KIV-119 Non-standard Communication/COMSEC equipment
    2 ARC-210 Non-standard Communication/COMSEC equipment

    Also included are spare and repair parts, configuration updates, communications security equipment and radios, integration studies, support equipment, publications and technical documentation, technical services, personnel training and training equipment, foreign liaison office support, Field Service Representatives’ services, U.S. Government and contractor engineering and logistics personnel services, and other related elements of logistics support. Implementation of this proposed sale may require the assignment of 10 each U.S. Government and contractor representatives in India for a periodic of up to 2 weeks.

    The principal contractors will be: Lockheed Martin Aeronautics Company in Fort Worth, TX and Rolls-Royce Corporation in Indianapolis, IN. Offset agreements associated with this proposed sale are expected per India’s rules covering foreign defense purchases, but they will be defined in negotiations. Note that Rolls Royce is already gearing up operations in India, and Lockheed Martin has offered to perform extensive F-16 assembly work in India if it should win the $6-10 billion MRCA fighter competition. DSCA adds that:

    “This proposed sale will contribute to the foreign policy and national security of the United States by helping to improve the security of an important partner and to strengthen the U.S.-India strategic relationship, which continues to be an important force for political stability, peace, and economic progress in South Asia. India and the United States are forging an important strategic partnership. The proposed sale will enhance the foreign policy and national security objectives of the U.S. by providing the Indian Government with a credible special operations airlift capability that will deter aggression in the region, provide humanitarian airlift capability and ensure interoperability with U.S. forces in coalition operations.”

    Dec 14/06: U.S. Air Force officials and others confirm delivery of an Indian Defence Ministry request for details of a possible purchase of 6 C-130Js, to the U.S. embassy in New Delhi. Per standard procedure, the embassy has forwarded it to the U.S. Air Force’s office of international affairs. See India Defence coverage.

    DID Brief: May 5/06

    Lockheed sources initially gave a figure of 12-13 aircraft as the number under discussion, which would take over the special forces role and supplement India’s current fleet of 100 or so medium lift twin-turboprop AN-32 “Sutlej” aircraft. No word on whether the Hercs in question would be C-130Js with minor customizations, or a J variant of the heavily-modified and much more expensive MC-130 “Combat Talon” special forces aircraft. India’s emerging Air Force philosophy and terrorism threat profiles would seem to suggest the MC-130 as the best doctrinal fit, while budgetary constraints (the MC-130H lists as $155 million in FY 2001 dollars, and an MC-130J Combat Talon III would cost more) would suggest the C-130J route. [DID: the requested equipment set and cost levels seem to indicate an aircraft similar to the Combat Talon]

    Also this pix comparing the sizes of the C-130 with the IL-76 which is of course the heavy lift a/c for the IAF..
