St. JohnSame old triple rack. The common launcher will need to be F-35 compatible.

ANKARA, Turkey — Rolls-Royce is offering its EJ200 engine to power the first Turkish-made fighter jet, Turkish officials said.
St. JohnNot really. IP of EJ200 is not Rolls Royce only owned. (oh well, it could be witha ood ararngement)
IP of XG-40-1/2 is though, and it’s basically the same thing as the EJ2x0 series.

St. JohnGiven that we haven’t left yet, how is that anything to do with Brexit? If anything this could be prevented by following the suggestion on the red bus.
St. JohnBecause the quality of a plane is measured using its sell numbers? (btw, the 170number is pure fantasy, nvm)
How else should it be measured? Number of fan blogs?
St. JohnOh dear, seems Nige was wrong here……
The government need to start unveiling some plans for proposed non-tariff barriers on EU vehicle imports in the event of a no deal. Because at the moment these guys are assuming it won’t be too difficult to export cars back into the UK.
The unfulfilled market demand for vehicles in the UK will be 2.3m following Brexit and in the EU it will only be 800,000.

St. JohnLook back at UK defence spending plans, the Captor-E was de-risked first as well. Page 65.

That was a very simple upgrade by comparison. Upgraded system of similar weight and size in existing airframe cavity. What you’re depicting is a dozen redesigned arrays with new TRMs embedded across pretty much every major airframe component, which will entail the redesign and structural re-testing of most, cooling validation, power supply validation, EMC testing, re-calibration of active cancellation, flight testing for weights and balance issues. Did I mention cable routing? Some of the arrays are in the wing LE control surface, so that will need retesting for aero-performance. And that’s before the capability/software upgrades, helmet, OSF, new weapons. Even the Nimrod MRA4 upgrade was relatively simple by comparison and need I say more.
But ultimately this does not matter because the absolute fact is that you cannot demonstrate any of this during the actual competition.
St. JohnCould be an EJ2x0 spin-off.
St. JohnDon’t buy it, who cares?
Just making sure customers don’t either. Hey I’ll build a completely new aircraft by 2025.
St. JohnThe Captor-E scheme first appeared when? And how many years between then and now? And that was a very simple upgrade by comparison. It’s taken 5 years since the development and integration contract was signed. But somehow here we’re talking about a new radar, an 11 array EW system, an OSF upgrade, a helmet and new weapons being integrated in the same time? Yeah I think my scepticism is based on experience and sound fact thanks.

The first batch of F4.1 Rafales will comprise 28 aircraft, already contracted for, while the later F4.2 batch will comprise 30 machines that are due for delivery by 2030.
St. JohnWell you were shown AFM interviewing a program director, an official publication from Dassault Aviation, an internal document from Thales where the image come from and you just decide not believing it. That’s your problem.
But I will nevertheles give you a 4th confirmation from the French air Force :

Problem is I’m familiar with the defence industry and I know how long things take and the changes described in that one diagram are more akin to a major variant upgrade than a systems upgrade. There is no way it can possibly be ready for 2025. GaN radar, yes, quite possibly, even probably but the rest no. I mean, remember that this Spectra system is supposed to do active cancellation with pin-point accuracy? Well you’ve just changed the positive of all the antennae and even the shape of the aircraft exterior. So isn’t that all going to need to be tested again? A while back I also heard some Rafale folk mention that phase interferometric sensors wouldn’t work on unstable airframe points like the wing, or the fin. I can see 11 completely new array elements plus the new radar, with many embedded in existing major airframe parts, meaning redesign of those parts and retesting. 2025 is a joke they’re going to try and sell to the Swiss and the gullible.
St. JohnYou’ve shown an image with completely new arrays added into the fuselage, wings and fin in several places, along with new TRMs and software capabilities and you want people to believe that’s a 5 year job. I think my scepticism is more than justified.
St. Johncheek arrays, really? did you read links? THERE WILL BE cheek arrays aon Rafale. See restless technophile or portail aviation. Official announcements.
If we’re talking about conformal radar. These were described as being a decade long multi-billion pound endeavour. Are we still talking about F-4 here or what?
If you’re talking about this:

I don’t believe for one second that will be developed and integrated with GaN by 2025. That’s not just a systems upgrade, that’s a structural reconfiguration. There are whole airframe components that would need to be redesigned and retested for that scheme, not to mention flight testing for weights and balance, EMC tests, functionality tests. If Switzerland believe that will be ready by 2025 then tell them we propose to turn the Hawk into an F-22 by the same date.
St. JohnGaN is much more performant than GaS, that did not mean GaS did not work well, it is just that the future is with GaN, it is the next big leap in radar tachnology.
As for rafale F4, development has been contracted and till date Dassault/Thales/Safran/MBDA were always on schedule for the rafale program unlike some of the competition due to a lack of political support. There is no reason to believe it will be late at this stage. Program history speaks for itself.
I maintain that F35 EA is limited to the frontal areas. Other antennas are here for self protection (EW) not EA, too small for that role. Rafale F4 won’t just have “antennas” but MFA compatible with EA. That’s two different things.
I think you have some difficulties admitting the rafale F4 brings some trully innovative feature that are genuinely “disruptive”…Even the F35 is left behind with those GaN MFAs+AI.
Go on Dassault official publication if you want to double check. Page 4 :
http://www.defense-aerospace.com/dae/sponsors/sponsor_rafale/img/fox3_20.pdf
It barely makes up for the radar size deficit and does not make up for beamwidth disadvantage or AoR disadvantage. Bandwidth is a fringe benefit at best.
I don’t believe that to be the case. Sometimes difficulties arising during development and integration go beyond mere lack of political will. You could encounter technical problems on the way, perhaps even insurmountable ones.
And I’ve shown you a link stating that it isn’t. How are the antennae covering the wing LE and TE of the F-35 small relative to those little 3 patches on the Rafale?
I think you have difficulty realising that what might be in 6 years, might not be and certainly isn’t at present. Rafale might have GaN radars in 2025 and so might the F-35 and Typhoon. Northrop Grumman at least have GaN radars in service today, albeit not fighter ones. So I would say the F-35 is more likely to have GaN arrays before Rafale. And a 4-8 fold radar power increase is no match for a 1000-fold RCS reduction. But ultimately 6 years away just isn’t now and can’t be assessed as such.
St. JohnPESA had advantages but were suposedly inferior in range comared to mechanical radar. I already participated in the debates at that time in 2008/2009 and for the Typhoon supporters the captor M was definetely supperior to the RBE2. This evaluation was quite a shock.
GaN advanatge is not only power but ease of simultaneous type of usage, like EA and coommunication also bandwidth etc etc
For the Typhoon (or F35 to a lesser extent) It could be our it could not be, just that you would need a big surprise from the political sphere to push for it and I don’t see that for the moment. With “if” you can imagine anything.Development started earlier with PEA program for derisking. It will be ready for this competition, timing is perfect. And as already said from 2021 rafales will be F4.2 compatible.
F35 EA is restricted to frontal emisphere, you are mixing things with EW for self protection.
Range is defined by engagement (burn through). Detection is about scanning rate. You’ll have to prove the issue of simultaneous usage ease for GaN because the F-35 radar manages those things fine with GaAs.
Or for the Rafale, it could or could not be. Anything can happen in 6 years, yellow vests on the rampage, another crash. The link I provided also states that the contract for development and integration was only issues last week. ‘Development’ is pretty open-ended really and prone to delays and problems. People argued back in 2008 that Captor-E would be read in 6 years, but guess what, only Captor was assessed because in reality only it was functional. Same rules apply to F4.
And work has been ongoing on Bright Adder for some time too. Another issue is AoR.
EA is not limited to the radar for the F-35, it is a combined system utilising far more antennae if you read the link. The radar and MADL antennae are just resources it draw upon.
