    I think it is rather the state of France that play tough,
    neither Dasssault or its sub contractors wants to carry on with Rafale in France, its unprofitable.

    I don’t think that profitability is really the problem. I see those declarations more as a leverage action on the French government.

    This one is interesting if separation can be done reliable during maneuvering,
    it promises to bring up Pk of BVR on par with WVR missiles.
    […]AAM/ARM

    The main prob is not in the separation IMOHO but more in the linkage device that hve to be made rigid, reliable and light. Do not forget that an a2a missile hve to be carried by a plane and spend most of its operational life (during a conflict) hanged bellow a hard maneuvering plane with all the vibration induced by the flight.

    The challenge of such a design hve always been gruesome especially regarding the weight consideration. That nowadays, with all the new tech material and it’s legacy experience from the GenDyn AIM154 story, LM seems confident enough to push it frwd is understandable. The de-risking phase however is still rocky especially comparing the approach taken by its competitor.

    Nah. His wouldn’t have such a simple decadent convergent inlet. Good only for the west. I guess he would hve modded it with some kind of DSI (I bet he as a good breath too!).

    Most probably, adding yet another level of complexity might have scared the hell out of any customer.

    i love the part “google” on a prototype. Btw software isnt ready afaik. 3D thrust vectoring was originally planned asa Tranche 3 implementation, but lack of money… Which is a pity, it would have been a perfect add on to Typhoon aerodynamic formula (long arm moment canards)

    Front landing gear is under air intakes good luck for reinforcing that (possible, but expensive), + all softwares to land on a deck + materials etc that must be resistent to corrosion + etc.
    Possible? No doubt. Realistic? No. Considered by indian navy? In his dreams. And damn costly!

    The “check your sources part is really funny, a classic ๐Ÿ˜‰

    Regarding the 117 (he argue that navalizing the 117 only required to add a hook), the naval version that was proposed to the navy required extensive modifications, to the point that you don’t really need to be an engineer to see that both were different design.

    France formally accepts A400M transport

    Extracted from the same article:

    โ€œThe A400M saga is rich in lessons for future multinational defence co-operation in Europe,โ€ says Enders [CEO of EADS], โ€œWe must avoid unrealistic schedules and insufficient funding, and requirements which sometimes go beyond what physics can deliver. We must avoid juste retour demands that often do not allow for efficient programme structures and the selection of the best performing, most competent partners and suppliers.โ€ Europe should also strive to establish a single body to conduct military certification activities”

    As Tu22M has pointed out you clearly have little knowledge of European low observable programs such as the MBB Lampyridae.
    Thus your simplistic position is understandable, if however clearly inaccurate to those with knowledge and a little understanding.

    Edit: Whilst this page is from Wikipedia… a cursory glance shows 10 European designs out of 60 or 16% with 20 US designs or 33%. These are the ones that are acknowledged.
    http://en.wikipedia.org/wiki/Category:Stealth_aircraft
    Thus 16% of all low observable platforms be they research or production have originated in Europe. Given these figures it is hard to be able to claim a European lack of interest or knowledge as your original post attempted to.
    Sorry if this upsets you but i am fed up with throw away comments such as your original and subsequent which are clearly based on a lack of knowledge of the facts or poor understanding of those that are known.

    Perhaps it would be better if you got used to basing your comments on factual data.

    I mainly noted that adding another layer of insult without taking any responsibility of the former doesn’t bother you that much. Typical.

    But if you can draw a conclusion after my 3 lines of apartรฉ, what else can I say ?

    I don’t dance.

    Frankly I was going to delete my message. But since you quoted it… it’s too late!

    IMOHO BiO quoted the article in this very topic (Syria) to give a hint of what kind of “strike” was envisioned for the Syrian crisis.

    Rapid Raptor package: U.S. Air Forceโ€™s new concept for deploying four F-22 stealth fighters in 24 hours

    http://theaviationist.com/2013/09/29/rapid-raptor-package/#.UkhRpWSsgXw

    Frankly when I read that:

    It must be noticed that, even if such kind of deployment could be completed fairly easily, quickly and possibly in a stealthy manner, it involves just two pairs of Raptors, a ridiculous amount even for a small scale operation.

    I wonder what hve gone in the mind of Cenciotti .

    Failing to understand that with 200+ C17 and ~100 C5, the USAF managed that way to only rely to 1/6th of its transport fleet to support the forward deployment of its entire fleet of next gen air dominance assets in a discrete manner, is a fail.

    But giving the overall quality of his website, I guess this is perhaps a single unlucky occurrence.

    Industry concerned about US Navy UCLASS requirements

    http://www.flightglobal.com/news/articles/analysis-industry-concerned-about-us-navy-uclass-requirements-390817/

    Interesting BiO but they might be some technical problem that prevents the usage of a flying wing concept on an aircraft carrier. A flying wing depends on its control overall surfaces to remain controllable regarding yaw and pitch. The larger the wing, the easier it is.

    Late carrier testing MIGHT hve finger pointed this fact to the USN: the tech is not mature enough to safely land a small span flying wing on a carrier deck in adverse winds conditions. Those are only suppositions obviously. But if there is some truth in it, the logical choice would be to go for a more classical winged body, hence reducing the LO requirement that would hve no meaning with such config (winged body needs more RAM to complement their less LO shapes hence are heavier or carry less payload/range for a similar weight).

    So let’s resume:

    IF NOT safe_landing THEN
    FlyingWing.cancel
    WingedBody.create
    IF Payload/range=priority then
    LO = RelaxedLO
    Else
    //C’mon this is the 21st century USN!!!
    goto line above
    END IF
    END IF

    Note1: the Russian seems to work on a different concept with variable camber (the variable incidence test drone – early phase)
    Note2: I am pretty sure that I hve seen moving wing tip in a picture you posted (Boeing)
    Note3: there is some other solution to the prob
    Note4: given that shape is all abt LO (not really but almost!), it might be too early to make a public release of the concept or mass produce in the eyes of all.
    Note5: they might even get the Avenger as a smoke screen ๐Ÿ˜‰

    That just seems overly simplistic. The shock cone is 3D, so simply using side profile isn’t going to cut it. Also, despite the F-16’s sharper nose, its max speed is lower than the F-15’s.

    yes but let’s hve a look to two orthogonal sections of a plane, one hve the full wingspan in it, the other hve the fuselage profile.

    What would be the limiting size factor that will prevent such section to fit inside a mach cone first?

    Obviously the one containing the wing span (this unless the wing is highly swept and the fuselage so short that it needs a very tall vertical tail, this aggravated by a AoA capability requirement – this is where a double tail can help).

    This is why, reasoning within the plan of the wing is a valid assumption.
    ———————–
    Regarding the drag of the Su27 and its lifting body configuration, one hve to understand that the lifting central body was an adaptation of the initial configuration (from body tunnel shaping to lifting body).

    The T50/PAKFA is designed from scratch so it uses a rather more acute version of the concept. Looking at some Draken’s diagrams might be a better comparison.

    Integration of Meteor would mean death of AMRAAM program…

    And in reverse, NOT integrating the Met on the 35 was a plus for the export chances of the Raf/Typhoon.

    But since now, with the recent success of 35 sales to Eu countries, the fire is in the house, the “embargoed” integration doesn’t makes any sense anymore for anyone (if it had once).
