    It is also interesting which Version of the R77 was taken. Cause the new ones outclass the Meteor.

    Most unlikely.

    According to Russian sources, even the planned Izdeliye 180 upgrade of the R-77 expected to enter service around 2014 is only intended to match the performance of the AIM-120C-7. Vympel is on record as saying that it has abandoned its work on a ramjet-powered variant.

    It turns out that my memory is at fault. The information I was looking for had not been posted on this forum.

    What can i say? Fine example of profesional journalism…

    Ms Alexandrova is not a defense or aviation journalist, so I don’t think we can read too much technical import into her words.

    For the non-specialist journalist, the important skill is to be able to gather information on a subject about which you may have hitherto known nothing, compose a reasonably accurate account (using correct spelling and grammar) of what you have been told by your source(s), and get the end result to the copy desk not just in time to meet the deadline but also to fit in with the copy desk’s workflow.

    To paraphrase a line from the 1960s musical ‘Hair’ – “Don’t knock it if you haven’t tried [to do] it.”

    The tank section (most of the length of the vehicle) was delivered to Stevenage from Hatfield already mounted in its handling frame.

    Once all its systems and the propulsion bay was added, the vehicle (still in its handling frame) was taken by road to the Spadeadam Rocket Establishment, where it was checked out in the preparation area, then moved to Pad 3A and lifted into the vertical position. The handling frame was then removed, and over a period of weeks the vehicle was prepared for static firing. After the static firing, the handling frame was then reinstalled, the vehicle was lowered, then returned by road to Stevenage.

    So that was the general pattern of events. The vehicle was always in its handling frame except when it was mounted on the launcher.

    After any refurbishment work at Stevenage, it was then delivered by road, sea and road to Woomera, were it went from the preparation area to Pad 6A, where it was raised to the vertical and the handling frame removed. After a checkout period of several weeks, it was finally launched.

    I am halfway through an excellent book on the subject …

    What was the name of the book?

    There were too many Thor versions to fix a specific dry weight

    I was asking about the operational *combat* version, which to the best of my knowledge existed in only a single variant which was based in the UK and operated by the Royal Air Force.

    http://www.designation-systems.net/dusrm/m-17.html

    I’d already found that website. What I needed for a specific research project were the following data for the operational missile:

    Empty weight without warhead
    Propellant load
    Warhead weight
    Weight of lubricants, compressed gases, etc

    I have approximate figures for the R&D configuration used for early development flight tests, but not for the combat model.

    There seems to be very little information around on Thor. I tried asking the RAF Museum if they had any detailed manuals on Thor that would give detailed info such as a weight breakdown of the operational missile, but they were unable to help and suggested that I try the manufacturer. Given that Thor was made by Douglas, later absorbed into McDonnell Douglas, that was later absorbed into Boeing, there seems little chance that much will have survived.

    Click on the ‘Contact the Department of Research & Information Services’ on the Hendon website, and you are rewarded with:

    “We aim to reply to enquiries within 20 working days. If you have an impending deadline, please menton this in your message.” [The misspelling is theirs.]

    How many of us are expected by our employers to get through a large amount of work in the course of 20 working days (= a month), not just to “aim to reply”?

    If I don’t reply to an email in a day or so, I can expect to be hearing from my manager.

    Shouldn’t have been 30N6-1, that’s the radar set (in native form for the S-300PM-1) also known as 30N6E1 used in the S-300PMU-1. It would have been a 5N63S or 30N6.

    The 30N6-1 designation of the Slovak S-300 radar was given in the April 2005 issue of ‘Jane’s Missiles & Rockets’ by Miroslav Gyürösi. He is a Bratislava-based defence journalist who speaks the local language, understands technical Russian, and specialises in missiles, so is unlikely to have got the designation wrong. My guess is that he got the info either from the radar crew or from the radar itself.

    Found this: http://www.aviationweek.com/aw/blogs/defense/index.jsp?plckController=Blog&plckScript=blogScript&plckElementId=blogDest&plckBlogPage=BlogViewPost&plckPostId=Blog%3a27ec4a53-dcc8-42d0-bd3a-01329aef79a7Post%3a710a5216-59db-44d3-86ef-9aa5cfecfd90It seems that the desired range is 100 Nmiles.

    Bill Sweetman’s tentative identification of this as a test vehicle for the Office of Naval Research High Speed Anti-Radiation Demonstration (HSAD) programme seems realistic, though I don’t think he is right when the says that “HSAD combines the seeker head and guidance electronics of the AGM-88 HARM with a wingless airframe and a ramjet propulsion system”.

    Science and Applied Technologies (now part of ATK) was given a contract in 2002 to supply a forebody section to be mated with a new integral nozzleless rocket, variable flow ducted rocket ramjet propulsion and steering control subsystem in support of the HSAD project. This was based on AARGM rather than the standard HARM. The tail end of the round was by Atlantic Research.

    Based on the picture and this, http://www.mbda-systems.com/mbda/site/FO/scripts/newsFO_complet.php?lang=EN&news_id=224 , could it be that they took technology from the MBDA Meteor program and applied it to the AGM-88E ?

    That Meteor-style layout has also been used in US concepts/projects.

    But for the moment, I need to head back to the dinner party…

    Then select an image from the left, and underneath the preview on the right hit “Download Full Image”.

    As an aside this is probably related to the AARGM program.

    SOC, you have the advantage over me of not having consumed a glass of 10 year old tawny port, then half a bottle of wine (dinner party prior to my wife’s departure to the USA to visit relatives…)

    I’ll try to get onto this in the morning – that missile configuration looks terribly familiar. It’s not the current AARGM, which re-uses the HARM motor.

    Where did you find the high-res pic? The website you gave the link for only has low-res versions of the images…

    The better the images, the easier it will be to get an ID.

    Nice pics, Rajan.

    However, a quick check of the DRDO website shows that the link to the Aug04 publication from which they were taken seems to have been deactivated!

    Do you have the text and captions that accompanied these pics?

    If you have, and they are too big to post here, drop me a message and I’ll send you my email address.
