    Not 180km anymore ? and well single burn engine means it use Boost-glide trajectory. You boost to apogee, and glide from there where your airframe will attempt to maintain near max L/D ratio.

    You can use that trajectory even with dual-burn.

    Do we have size estimate ?

    Looks to me like it is pretty similar to AMRAAM. perhaps it has 200mm diameter as R-77. AFAIK it’s been claimed to have long reach of 150-200 km. I found it rather hard to believe, for at least missile of its size. Running few numbers and assumes AMRAAM like battery capacity for controlled flight (150 seconds). M 1.2 launch speed and 15000 m altitude and missile L/D of 2 (typical for axisymmetric airframe) i found the trajectory for boost-glide profile range is like 60-68 NMI (111-120 km). putting it within the envelope of the latest AMRAAM and R-77-1.

    AIM-120D is rated at 160km and is 180mm diameter with a single-burn engine.

    Readiness or operational readiness? Different metrics in France. If you want an operational case context, see Libya instead. (e.g.). It’s been discused ad nauseam but should better be placed in Rafale thread no?

    What else would ‘readiness’ apply to for a fighter aircraft?

    Yet more fines for the leave side of things, good to see this corrupt activity addressed.

    It’s a shame that KCL and UCL didn’t get fined every time they published research that turned out to be wrong.

    I’ve not had that problem yet with MB.

    Yeah, or like asking for a second referendum. But then the EU is founded on doing the same thing over and over until you get a different result. EU Constitution (rejected by referendum) -> Lisbon Treaty (rejected by referendum in Ireland) -> Lisbon Treaty signed.

    I have to say for once I appreciate this sovereignty and parliamentary democracy “so close” to the Brexiteers hearts…..

    “Bercow disallows MV3 if it is substantially same as MV2, as the government cannot keep bringing the same motion back to the House again and again.”

    A parliamentary procedural rule dating back to 1604.

    Brexiteers fully support this too, that deal is worthless, we don’t like bringing the same thing back to a vote either.

    You’re wrong on both counts, the eveidence is there for you if you choose to read it, and the EU has done a lot more preparation than the UK which amounts to nothing, apart from the odd non existent ferry contract.

    Yes but they aren’t expecting several recessions, which seems very likely. And whilst they’re talking about expanding Irish port capacities, so far they’ve done sod all, nor is it clear who will pay this extra money, or Britain’s old share. I doubt they’re as prepared as they’ve made out.

    I’m sure Russia would like that, after practicing their technique in the UK I’m sure they’ll be active in italy now too.

    Give us a break.

    Bradburger raises a good point though, Britain has been prepared for it to be bad with endless negative forecasting, the EU is dancing merrily into a no deal scenario as if it will have zero impact.

    “Can’t have circulated widely”?

    It was circulated in front of Boris, Fox and Duncan-Smith. I’ve shown you images of it both from national press reports and TV. It was the original billboard poster for Vote Leave and was also distributed as a leaflet form. Bizarre!

    https://www.itv.com/news/update/2016…ndum-campaign/

    I followed the Brexit campaign intensely and have followed the debate since. I’ve seen the bus many many times, but I hadn’t seen that until now. So like I said, it wasn’t distributed widely.

    But so what. £350m is the gross figure and maybe even the money we get back is spent on BS, instead of the NHS, where it’s most needed. The other side also got chance to refute, debate and rationalise this figure during the campaign too, just as that linked article does.

    I was referring to the new stealth aircraft to be developed with Russia.

    A new aircraft is going to take ages to develop though.
