    Another interesting thing about Pattle is the rapid timeline at which he scored his victories. He was flying in a theatre where his side was comprehensively outnumbered though, and was probably a contribution to his demise. (exhaustion/illness)

    On some of the figures, the Chris Shores and Clive Williams definitive study Aces High, which really digs into the matter, credits Pattle with 50 and 3 shared destroyed, and 7 and 1 shared probable. So perhaps the higher totals are not completely beyond the realms of possibility either.

    But its is generally acknowledged that he was probably the leading British and Commonwealth ace in WW2. Haven’t followed the argument to how many he “possibly” or “probably” achieved, but until the official records were lost, he had 34 confirmed kills, and many probables. Between that official last score, and his death, he definitely scored a host of other kills, as witnessed by fellow airmen and Axis losses. How many, we’ll probably never know, but it most likely took him to 40 and over, as is generally acknowledged. Perhaps he could have been approaching or around 50, but I think 60 is a bit of a reach….

    He was also noted as having been lax on claiming some victories, and letting his comrades take credit. Roald Dahl had an extremely high opinion of him, as did Air Marshal Sir Peter Wykeham.

    Can anybody recommend a good read on Pat Pattle btw?

    If J-10 weighs 8860kg than it is pretty much out dated.
    it is not multirole figher with heavy loads or have electronic scanning radar in nose or IRST.
    just adding IRST and electronic scanning radar will add 500kg.
    J-10 should not weigh more than 7500kg in air defence version.
    Rafale is better in TWR even with underpowered engines.

    There is no way the J-10 will weigh less than 8 000kg empty.

    It is clearly a larger plane than the Mirage 2000, and later model F-16’s, and indeed the Gripen NG.

    It has a large afteburning engine who’s weight is starting to approach that of 2 M88’s as used in Rafale. Seeing as the Rafale weighs in empty at around 9500kg plus, I’d assume a figure of around 8900 to around 9500 to be a perfectly reasonable expectation for a jet such as the J10, dependant on what equipment is inside.

    Ermmmm…. I’m tempted to ask you the same question :D, but I guess that we are looking at the same thing from a different angle. I’m a software man, so for me platform includes weapons systems. Besides I wasn’t contradicting you, simply pointing out that there were issues with the Rooivalk.

    I actually quite like the Rooivalk but it suffered from the same over-sophistication as the western designs of the 1990s, and unfortunately SA didn’t have deep enough pockets to save it.

    Ahh, ok then.
    The plan to fit the original sight was obviously hampered by the end of the Cold War and resulting drastic slashing of the defence budget in South Africa.

    Not the platforms fault I suppose. Part of the result was that a cheaper and simpler French sighting system had to be then chosen. As far as I know, the original sight was available to export customers.

    I suspect you know that many people would be amazed at the obsolescence of software/hardware in many aviation platforms from the late 80’s/early 90’s. There was a revolution as we all know during that period that is ongoing at present with regard to computers.

    Ironically, South Africa paid recently to integrate the Mokopa finally onto the Rooivalk, something that probably would been cheaper in the end by sticking to the original more capable sighting system.

    I always thought Mirage 2000 was comparatively very cheap to operate.

    Anyway Gripen NG already has two orders now, and the older variant has five,
    and those will naturally also be partly or fully be upgraded to NG standard,
    so that’s 7 customers/users already, -this will definitely weigh in favor of NG

    It may be that the Mirages are now due a major overhaul or something along those lines.

    This article is less glowing in its praise of the Rooivalk… :diablo: http://www.engineeringnews.co.za/article/what-went-wrong-with-the-rooivalk-2007-06-08-1

    Having said that, the Tiger is more a marketing success than anything else atm, so maybe there’s no jewel in the current crop of attack helos.

    Ermmmm…. have you actually read the article?

    It states basically everything I have posted above.

    The platform is first class.

    The avionics were the problem. There was an advanced sight developed, but a cheaper option was selected due to budget cuts post-Cold War. (The T-DATS can be seen on earlier Rooivalk prototypes btw.)

    It’s woes stem from budgetary cuts.

    Eurocopter in particular ensured it wasn’t going to compete with the Tiger.

    The Apache or the Mangusta would have done me for AIR-87. At least they would have been operational by now…

    The Tiger can’t say the same and based on South Africa’s issues with the Rooivalk it’s unlikely to have been ready by now either.

    South Africa’s issues with the Rooivalk were of a funding nature due to the fact that it wasn’t exported. If it had won export orders, this would have freed capital. Nothing whatsoever to do with the platform.

    A result of not winning export orders, and the trickle of funds that resulted, meant also that the original South African T-DATS sighting system was replaced by a cheaper, less capable French system. This then in turn led to having to integrate the heavy long range Mokopa anti-tank missile with this replacement sighting system, resulting in delays.

    An export order would have prevented all this.

    As it is, the Rooivalk is now fully qualified and operational, including with the Mokopa, and has been for a while now.

    So nothing to do with the platform, and everything to do with funding issues as a result of those lost export opportunities.

    Is General Atomics getting a licensing fee for this bird?

    Another piece of “original” kit coming out of the PRC I guess. 😡

    Have General Atomics sold some to China that were then reverse engineered?

    Personally I think the Rooivalk would have been a good choice for the Australian Defence Force (ADF)! The the fact that we purchased the Eurocopter Tiger, immediately negated any notion or sensibility of inter-operational capability with our two major allies – UK & USA!
    I personally saw the Rooivalk put through it paces at an Avalon air show many moons ago – and was thoroughly impressed!
    Talking to the flight crew and sales team, what probably sold me the most with the Rooivalk design was it’s true ability to operate in some of the harshest environments on the planet (the harshness of South Africa not being to different to the Australian outback!), for long periods of time, with minimal logistical support! Something the likes of the Tiger and Apache can not do! As a note, failing the selection of the Rooivalk by the Australian Army, I would have preferred the proposed Aussie tailored version of the A129 Mangusta over that of the Eurocopter Tiger!!

    Secondly, I am somewhat surprised that the PLA/PLAAF did not cooperate with the South African’s in using the Rooivalk as the basis of their own combat helicopter!

    China at one stage wanted to buy a very small amount of Rooivalks. Denel was suspicious that a reverse engineering project would be the end result.

    The Rooivalk was a very good, tough helicopter that has been hamstrung by industrial and political moves. It was rated highly by the RAF, but the US refused to integrate Hellfire onto the platform. This resulted in a tit-for-tat exclusion of US weapons in SA’s arms purchase a while later.

    Eurocopter put out pressure in the Australian and Turkish programmes about not supporting the engines on the Rooivalk, which are French.

    A helicopter that scored highly, and should have done better, but for the political angle.

    Today I learnt that some Mirage III variants were fitted with fixed canards.

    Where have you been for the last 30 years?

    The kfir doesnt just have canards, it also has fins on the tip of the nose to achieve the same affect. The cheetah has a strake on the side of the fuselage below the cockpit. These are all feeble efforts to provide forward lift leverage ahead the CoL.

    The Cheetah’s canards and strakes not “feeble attempts to provide lift leverage forward of the CoL”.
    They are a necessary addition to an aircraft that has a meter increase in length on the forward fuselage containing a multi-mode radar. It bought additional benefits that either you don’t care to mention, or don’t know about.

    An interesting topic, as the Al-31 from the Su-27 seems to have garnered much of the attention and funding to produce more powerful variants.

    Certainly though, more powerful and modernised RD-33 variants could be very useful addition to Russia’s stable.

    Video of the acceptance of the new Mi-26s.

    Sorry TR1, not being a Russian speaker, but is the Mi-26 still being produced?
    I was under the impression that production had ceased?
