    No. For one thing, the F-22 isn’t export-cleared – its systems haven’t been secured against leakage (unlike the F-35’s; notwithstanding the cyber-espionage embarrassment). For another, once the floodgates open, denying the same to Japan, Australia, Israel would have been perceived as a snub. Unless it was made available to them as well after which you have South Korea, Turkey and potentially others standing in line. Would have also hurt the F-35 program.

    The US did tentatively offer the F-22 to Australia in the mid to late 90s but the RAAF turned it down given the expected, and realised, sustainment costs associated with operating the platform.

    Both the UK and Australia have exchange pilots that fly F-22 so there was a 5th gen learning curve already started in both countries before F-35 arrived.

    WS-15 has never powered the J-20. WS-15 is still years away. So far there have been no leaks on engine fires on the J-20 AFAIK. The article alleges that during ground testing of the WS-15 there was an explosion at one stage. I wouldn’t be surprised if such a thing happened become this is uncharted territory for China. WS-10 development also went through a lot pain intially including a 2-year halt in powering the J-11B (2007 – 2009). But they eventually got it right and the WS-10 is now pushing towards 137 – 138 kN with the latest versions (WS-10X/IPE). So yeah, maybe there was an accident/explosion during ground testing of a WS-15, but not on a J-20. J-20 still uses AL-31FN/FM variant. There are 2x prototypes flying with WS-10X/IPE.

    Thanks for that insight.

    I wasn’t aware the J-20 had an engine fire in 2015. Did I just miss this or has it only recently been revealed? If so, interesting that all three new stealth aircraft, J-20, PAK-FA and F-35 have had engine fire issues during dev and test.

    Why China’s first stealth fighter was rushed into service with inferior engines

    China rushed its first advanced stealth fighter jet into service ahead of schedule last year, using stopgap engines, in the face of rising security challenges in the region, the South China Morning Post has learned. But that means its capabilities will be severely limited, affecting its manoeuvrability and fuel efficiency as well as its stealthiness at supersonic speeds. Without saying how many were in operation, the People’s Liberation Army Air Force confirmed on Friday that the J-20, the country’s fifth-generation fighter, had entered combat service, meaning it was combat-ready.

    However, the aircraft was equipped with inferior engines designed for earlier warplanes when it first joined the air force in March last year because “critical problems” with its tailor-made WS-15 engine, exposed by an accident in 2015, had not been fixed, two independent military sources told the Post.

    “The WS-15 engine designed for the J-20 exploded during a ground running test in 2015,” one source said, adding that no one was injured in the accident. “The explosion indicated the WS-15 is not reliable, and so far there is no fundamental solution to overcome such a problem … that’s why the J-20 is using WS-10B engines now.” The WS-10B is a modified version of the WS-10 Taihang engine, which was designed for the country’s fourth-generation J-10 and J-11 fighters.
    The explosion was confirmed by another source close to the military, who said the reasons it happened were complicated, with one being the quality control of its single-crystal turbine blades, the key component for such a powerful turbofan engine.

    Err.. the size of the antenna isn’t classified. And its entirely independent of the T/R density.

    You forgot that along with Spectra Dassault perfected the Tardis effect for nose cones… 😉

    Canadian firms could be in the running to repair F-35 parts – but will they succeed in such a bid?

    The US government is looking for a company to conduct future depot level repair of F-35 components for the North American region.

    Since Canada is still part of the F-35 program, Public Services and Procurement Canada is providing details to Canadian industry.

    The US government wants information from the firms and whether they can do the job. Key criteria include: existing capability, ability to grow, and labour costs.

    “The Canadian Government, as for all F-35 Participant nations, has been asked to distribute this RFI (Request for Information), collect responses, ensure completeness, and forward to the United States Joint Program Office,” Public Services and Procurement Canada noted. “The Canadian Government is not involved in the selection process. Completed responses will be required by the Canadian Government no later than 16 March 2018.”

    There are approximately 400 different parts and components to repair. Work would continue until 2040.

    What are the chances of a Canadian firm being selected?

    Canada’s aerospace industry has the skills to do the work.

    But the Canadian government hasn’t committed to buying the F-35 so that could be a factor. It would be certainly controversial among F-35 users to select a Canadian firm for this role, considering the government’s decision not to buy the F-35, at least at this point.

    However, if the US government wanted to solidify the purchase of F-35s by Canada, providing Canadian firms with this job would make it increasingly difficult to ignore the industrial benefits resulting from the F-35.

    RAAF Growler catches fire after takeoff incident during Exercise Red Flag

    An apparent engine failure has seen an RAAF EA-18G Growler catch fire after an aborted takeoff from Nellis Air Force Base, Nevada on Saturday morning US time.

    “Defence can confirm an incident involving an EA-18G Growler at Nellis Air Force Base during Exercise Red Flag. Royal Australian Air Force personnel are safe and no serious injuries have been sustained,” a Department of Defence statement released shortly before midday on Sunday (Australian time) confirmed.

    “Defence is currently working with the United States Air Force to investigate and will provide an update with further details once known.”

    The Growler’s crew, comprising a pilot and an electronic warfare officer, were able to exit the jet on the ground without ejecting.

    Doesn’t look like it will be a write off but there will be a decent repair bill. I suppose good news it happened in the US where there is plenty of experience and workshops available to repair a SH.

    Definitely has to be the Grognard…

    On a more serious note, it is a toss up between the F1 and the Sud Aviation Vautour.

    speaking of reliability..ive found this

    http://www.theaustralian.com.au/nati…5e097c5eacbd1b

    None of that is surprising. As I alluded to earlier the Aus DoD recommended the AH-64 and the UH-60M as the most mature, capable and lowest risk options for the respective helicopter tenders but they were overruled by the Government of the day who wanted to cosy up to Europe. Had the original American options been selected then both would have served with Australian forces in Afghanistan, significantly improving Australian operations, and likely reducing Australian and local population casualties, in Tarin Kowt.

    If similar deployments were on the mind of the BAF, they surely would opt for something else than a type which can only be procured in mere three dozen examples..

    The BAF sought responses from five manufacturers. All five airframes, especially in the timeframe that the BAF is looking to order, are probably within 15-20% of each other for acquisition and again similar for operating cost. The BAF is also seeking a multi-role airframe to replace the F-16, so they require A2A as well as A2G capabilities. A mere three dozen examples as you have claimed would not marginally be impacted by one type over the other from a cost perspective. That three dozen number is dictated by budget, not by airframe. Had the Belgians dedicated the same ratio of budget as when they acquired the F-16, they would be looking at 80+ aircraft.

    ISIS has no air force and no SAM defense network to cope against

    You keep wanting to plan for the past and not the future…

    what really counts is numbers, readiness, reliability and turnaround times.. hardly parameters where a complex type like the F-35 would excel in..

    Except all five are essentially no more or less complex than each other and in the case of the F-35, despite your poorly informed comments, the vast number of airforces choosing that type clearly indicate that isn’t a concern.

    Because such capability requires global ambitions.. BAF won’t encounter an enemy SAM system until trying to perform offensive missions.. well, they have shown little interest in such activities back in mid 80s with 160 F-16s in hangars and Russians stationed around Berlin, why should they do it now, with no enemy in sight and mere 34 jets on order?

    Why do we need to directly relate the decision in the early 1980s, when they made a decision on what they could contribute to NATO that would best support and enhance the overall capabilities required, to 2017, 40 years later…

    A sustained campaign with such number of aircraft? Forget it.. That’s hardly enough for permanent QRA service plus few airshow specials..

    As I said above because Belgium obviously see themselves having a role in international actions in the future. How and in what shape they come are currently unknown but having the most options to assist makes sense, especially since all the respective manufacturers offering jets cover to some extent that mission set.

    except that: what business do they have to go around the globe in the first place?

    I don’t know, maybe that crazy notion called international alliances. The BAF flew in Bosnia, over Afghanistan and against ISIS, perfectly justifiable international actions where the BAF was able to contribute airpower to an international coalition.

    JDAM procurement was indeed around 2005 and Sniper XR the following year.

    And given JDAM didn’t IOC with the US until 1999 in one variant and later for additional weapon sizes 2005 seems a very reasonable timeframe for acquisition.

    Which is precisely my point.. BAF has no interest in SEAD.. This requirement is completely bogus in order to get more points for the F-35.. The whole “competition” is staged from the outset, with only one possible outcome..

    Why can’t they change their mind? The BAF has obviously reviewed the future threat battlespace, and like a host of other nations including Russia and China, have decided that different concepts/mission/capabilities are required for future operations. In the BAF case they consider SEAD/DEAD a viable mission set in the future which, given the large number of advanced SAM systems proliferating around the globe, seems a wise decision.

    I don’t remember any of the details, but there was a document published that outlined some scenarios (various missions). As far as I recall some of those missions had SEAD/DEAD components, and in general 4-ships were to be used with no extra support.

    I don’t have time to dig out the document right now, it was made available when the competition started. I assume it’s still available.

    I found the older article that indicated that the floor damage was not just high heels (which came at a later airshow), but boots:

    The Australian Department of Defence found similar issues. Essentially the helicopter was not equipped for battlefield conditions and none of the systems were currently capable of operating in a high threat scenario. Some of that blame lies with the Aus DoD who demonstrated some poor project management and requirements definition (although in their defence they recommended the UH-60 and were overruled by the Government of the day) but also the immaturity of the design, even in 2014, was pretty clear.

    During the audit, the MRH90 Program was dealing with a range of challenges related to immaturity in the MRH90 system design and the support system. The challenges include:

    resolving MRH90 cabin and role equipment design issues so that operational test and evaluation validates the MRH90 aircraft’s ability to satisfy Operational Capability Milestones set by Army and Navy;
    the continuing need to conduct a wide range of verification and validation activities on problematic or deficient aircraft systems;
    increasing the reliability, maintainability and flying rate of effort of the MRH90 aircraft;
    embedding revised sustainment arrangements directed toward improving the value for money of these arrangements;
    establishing a revised Australian industry activities plan, including performance metrics;
    funding and managing the extended concurrent operation of the Army S‑70A‑9 Black Hawk and MRH90 aircraft fleets; and
    managing a Navy capability gap following the retirement of the RAN Sea King aircraft in December 2011.

    Pure blah blah. (especially the last sentence). Oh incidentally there is atm a belgian government team discussing the french offer details atm in Paris…

    Please point out any of it that isn’t correct Halloween.

    Any guess why Belgium have a delegation in Paris right now? Because France/Dassault didn’t provide any info to the RFT. Don’t be surprised when a non french airframe is selected and one of the primary feedback points provided will be a lack of valid tender submission.
