    I wouldn’t be so sure about taking the Swiss decision as a benchmark Tonnyc, yes they have moved to using the PC-21 for BFT, AFT and finally LIFT but the school is rather out on it’s success. There have been rumbles from the Swiss Pilotenschule that pilots are arriving at the OCU unprepared for the performance jump. Leading to changes being needed in the OCU burning more hours on more expensive fighter airframes.

    320kts to 360kts is a bit sedate for various training exercises and might not provide enough work load for the trainee to weed out the unsuitable for higher performing aircraft. Many a promising student who sailed through the AFT stage was washed out at LIFT because they couldn’t handle the workload of a low level 500 kts nav exercise. Dropping the jet based LIFT means that rather than finding this out at LIFT on a cheaper jet trainer this happens at the OCU costing time and money. If a pilot can’t handle the load at LIFT there is a chance to push them down the multi engine transport route or onto helicopters.

    Well well well, look at this hanging off the wing of a JH7A at Zhuhai:

    A Sino-AGM-154…

    Bet that will cause some interesting debates back at the Pentagon and the Air Power Australia web-site to go into total meltdown…I wonder what panicky the end is nigh gems old Carlo Kopp will come up with over this one!

    I think it was a rather clever pragmatic choice by the Chinese to fit the prototype Y-20 with D-30:

    1) It ensured the program wasn’t delayed whilst awaiting an indigenous engine
    2) It is a mature reliable engine already in service with the China airforce
    3) It will allow performance comparisons with the il76, if the type has more advanced aerodynamics then it should out perform the il76
    4) If the indigenous engine intended for the type is delayed for any reasons they have the option of importing more D-30 and getting the type into production

    The picture alongside the C17 certainly shows where the Chinese drew some influence…

    in reply to: Red Arrows – are Danish F-16s the replacement? #2215643

    There are several layers to consider with this but lets deal with the F16 issue first…

    It isn’t going too happen, it is an alien type to the UK logistics chain and it makes far more sense to procure more Hawk T2, the CO of 736 NAS was clearly playing mischief with the press. He knows full well it would never happen but he threw the concept out there fully knowing a rag like the Express would bite and the perennial Red’s replacement arguments would crop up. I bet he is having great fun laughing it up back at base with his fellow NAS members.

    Now looking at the Red’s replacement issue, if they are going to be retained it will be a Hawk T2 variant in all likely-hood. Cost wise the Reds are not that expensive on an annual basis and the government of the day would suffer a severe PR hit cutting them. Now as it stands the Hawk T1/1A are on their way out and a further follow on T2 order for the RAF and Royal Navy would not be a bad thing. Lets be clear any more procured will not be purely for the Red’s or 736 NAS, they will be added to the current pool of aircraft and rotated as needed. It makes good economic sense for the MOD to increase the Hawk T2 pool whilst BAE Systems are still servicing export orders for the type.

    Looking at the Red’s in particular it should be noted that the rumour grape-vine has thrown up some objections to the Hawk T2 as a steed for the team, frankly take them with a pinch of salt. Firstly cost is raised as an issue, well maybe it has got more complex avionics but increasing the general pool of the type would help with economies of scale. Also deleting the T1/1A from service would offer cost savings as the UK would be only operating one Hawk type. Another thing older aircraft like the T1/1A usually require more general maintenance in relation to their flight hours.

    The other issue raised is the manoeuvrability argument with the rumour grapevine stating Red’s insiders prefer the T1A over the T2 in that respect. All very well but so what? This is not the first time the Red’s have had to adopt a new type and change their display routine, many Red Arrow old boys and fans alike talk wistfully of the Folland Gnat days and twinkle rolls! They can adapt and I really don’t see it as a deal breaker, any pilot who is wearing the Red overalls who gets too vocal on the matter will be quietly taken to one side and have these words whispered in their shell like ears:

    “If you know what is good for your future career in the RAF be a good chap or chapette and wind your neck in…”

    I fully expect the 2015 SSDR will lead to a further Hawk T2 batch being purchased and the 736 NAS/Red’s replacement issue quietly going away.

    Original was Dong Hae class rather than Pohang as had been expected. Still surprising. Maybe just a temporary configuration for the transit and further changes will happen at COTECMAR?

    I doubt it is a temporary configuration, there has been a fair amount of metal cut and added to mount that forward twin Bofors L60 mount. They probably don’t need the anti ship capability of the AShM and the OTO-76 is a fairly expensive and complex piece of kit to maintain. In its new patrol role with Columbia the new (well old actually) 40mm is probably more then adequate and cheap to maintain.

    Can the MiG-31 intercept and shoot down Mach 3+ targets? When was this proven?

    What types of target drones capable of simulating aircraft flying at mach 3.4 were used when testing the R-33 missile?

    I think we get into the world of the theoretical here, as I understand it both Russia and Israel both looked into and planned to use what was in effect a computer timed Ground Controlled Intercept (GCI).

    For Israel it was to deal with high flying reconnaissance Mig-25 and would involve an F-15 armed with Sparrows making an intercept. When the Mig-25 was detecting approaching their airspace they would calculate the flight path and direction then launch the F-15 at the right moment to allow a zoom climb in the right direction followed by a Sparrow launch.

    As I understand it Russia planned to do a similar thing with their Mig-31 and R-33, I vaguely remember reading a report of such an intercept (with out the launch of course) and it required the Mig-31 to get off the runway and into its climb at a very exacting computer calculated time. The R-33 would also launch automatically based on the geometry of the intercept and data sent to it from Ground Control. If they missed the runway launch by even a few seconds the intercept theoretically was a scrub.

    Mack8 you are rather wide of the mark on this one, the Romanian’s in the early 90s had 20 or so recently delivered Mig-29. They were struggling to get spares off the Russians for those airframes. They had a large number of stored Mig-21M and Mig-21MF stored that could form the basis of an upgrade program plus large numbers of other variants retired or still in service to provide spares plus an overhaul facility familiar with the type.

    Considering the difficulty in keeping the Mig-29 running when they could have full control of an upgraded Mig-21 they made a pragmatic decision considering the local threat environment.

    Whilst it doesn’t have the cachet or excitement of the J-15 or the new 052D Destroyers the new Y-8FQ is probably one of the most important assets required by the China Navy. A decent, modern long range MPA/ASW/ASuW aircraft has been desperately needed if they expect to able to project themselves as a Blue Water Navy. The current fixed wing MPA/ASW assets are woefully obsolete and lacking in numbers.

    What interests me is if there is an export market for this type, certainly could see Pakistan taking a look at the type to supplement their P3.

    http://en.wikipedia.org/wiki/Mokopa

    After the US refusing to release the Hellfire for integration on the Rooivalk during the British attack helicopter competition, Mokopa was developed.
    It comes in MMW format too.

    Rooivalks potential for sales are/were not performance based.
    They are political.

    When in competition with the Tiger, a European engine manufacturer suddenly started making statements about not supporting it’s engines if Rooivalk won.
    Add the US missile refusal above, and various behind-the-scenes shenanigans in other competitions.

    You can have the best platform in the world, but it counts for nothing when related industries are reigned in for political reasons and used as bidding tool weapons. This applies to any platform.

    I think general anti competitive shenanigans from other parties is only part of the story. The market for attack helicopters both new and used is almost saturated with choices currently. That does make it rather difficult to penetrate the market as it stands, I do wonder in respect of engines if they might of been served to look at some alternate solutions to reduce the issue of sales being blocked by particular parties.

    KC-390 is failed project from the start. Brazil neither has the budget nor exports to sustain the production that is dependent more than 90% on US/EU components.

    MTA has solid foundation based on IL-476/MS-21 supply chain.

    Fairly common practice for military aircraft to carry a civilian serial whilst undergoing manufacturer test flights. For example here is the RAF A400M with a civilian serial number:

    Australian? Naah, he’s a Yank. He spent his teens & early 20s in Oz, & visits, but lives mostly in his home country.

    I presume he likes making anti-English fiction films dressed up as history because he inherited a hatred of England from his dad.

    And that’s all I’m saying on that topic.

    Outlines the overall plan

    Essentially 12 Typhoons, with initial and advanced training outsourced most likely to rUK but possibly elsewhere within NATO.
    6 Herks and a mixed rotary squadron.

    Likely RAF keeps 2 squadrons of Typhoons at Lossie, whist ScotDF stands up it’s first (Scottish pilots from the RAF).

    In the future 4 MPAs (possibly as part of a joint buy -larger order …economy of scale and co-operation), more Typhoons. RAF involvement at Lossie reduces as more ScotDF Typhoons come on line (probably 2 short squadrons).
    Other things to be added after defence review.

    I almost posted that list myself, it is pretty much unworkable and the SNP know that as well.

    They talk about “x number” of airframes, with UK support until they are up and running with Scottish personnel to operate them. Looking at the airframes first:

    12 Typhoon, a very expensive twin engine air superiority fighter and they can’t assume they would get after negotiation Tranche 3. Most likely it would be Tranche 1.

    6 Hercules, a type very nearly out of RAF service and by all reports nearly worn out. So are they talking about buying new examples or refurbishing the old?

    4MPA, would have to be off the shelf and they would have to set up from scratch.

    Looking at personnel, it is a rank assumption that the UK defence infrastructure will just support a nascent Scottish Defence Force. If it did there would be a cost. There is no training infrastructure in Scotland for the Typhoon or for that matter frigates like the T23. Personnel would be the biggest problem, many would not leave the UK armed forces for an SDF and it would more then likely be not possible to fill the trades needed to support the different types the SNP say they can.

    Now the SNP know this and would blame Westminster then set up a more realistic SDF.

    Which is best? I have heard of 120 mm is more stable than 125 mm, 125 mm suitable for tanks loaded automatically?

    Ah this brings back memories of the Army sub forum.

    I have a friend who was on the trials team for the Challenger II tank, I posed him a question about 120mm vs 125mm and his answer was there really wasn’t anything in it the difference is so small. There are other variables that are more important when it comes to accuracy like calibre, ammunition/propellant quality, barrel alignment and the fire control system.
