But this is crazy. If there is a general war with Russia in the next 5 years (we've been hearing that since 1946) then its immaterial anyway whether GCAP goes ahead. Even if we ordered 500 F-35s tomorrow they wouldn't be delivered in time, we might get a squadron of Typhoons maybe, but given such a war would likely end up with instant sunshine dished about and we'll have lots of other things to worry about that "I wish they had ordered 1,000 GCAPs for 2040".

There seems to be a lot of death wish fanaticism going on, Justin Bronk's argument seem fallacious in several respects.
Everybody needs to remember that this is our money going down the drain (hopefully, otherwise that'd mean war) optimistically there needs to be less spending for such useless things so anyone competent wouldn't really look for trouble.

F-22B that never was with updated f-35 nose profile. The increased wingsweep is maybe to compensate for how fat this thing is.
 
Article here. Nothing much new and no analysis of the new design (of course not - there's been no time to do so) and a few boilerplate industry statements - 'best thing since fried gold' etc. Still, a handy overview. No doubt more to come as the Farnborough show gets going.


Avweek here, much the same:

I wonder if they will consider canard in next iteration.

Maybe, tvc nozzle will buffer these major adjustment.
It seems dev team have confidence to use it all the time, so ruddervators were changed to small.( from this https://www.secretprojects.co.uk/attachments/img_1358-jpeg.711689/)
I don't know how to fit these system to the tail part of current CG.
Are CGs still placeholder?
Still under going by NGF budget, so I put in this thread.

No.28 : It seems like the fuselage design will get closer to the internal structure and there are plan of the trial construction for partial loading test.
No.29 : Contract for the manufacture of thrust deflector nozzles and other auxiliaries for engine on-board testing.
(推力偏向ノズルの研究試作契約 is contract for development and construction of XVN3-1、I don't know this contract inherit old contract for xvm-10, 2D tvc nozzle for XF3-400 engine)
Will they use 3D tvc nozzle that is improved one from XVN3-1?

no27, 30 are also related.

Personally, I'm starting to be concerned that it's getting too close to that of Lockheed Martin's fifth gen fighters and lacks futurism and originality. Of course, such designs have been proven, and would be the most efficient in terms of cost per performance ratio, but still, it's a 6th gen fighter...

And, for Japan, it would be like coming full circle if this design is adopted.

Not sure what to make of it yet to be honest. BAE Systems' big reveal in Feb/March had the cranked wing, now four months later an entirely different wing.
Perhaps it's a sign that there is/was internal disagreement over the wing layout and the Japanese team have won out with the delta?

We've seen plenty of models, plenty of CGIs, I don't think we'll get a real handle on what GCAP might look like until the demonstrator flies, and even then it might not be fully representative of the final design that ultimately gets chosen.

The point is to run a successful program and field a capable platform that can meet requirements then this looks good. If the point was to field something that takes a significant deviation from 5GFA and 5GFA+ concepts then that has to be balanced with risk, funding, technological development and a whole host of other factors. What we're seeing on US NGAD is backtracking on the program being too expensive potentially because it took a rather dramatic deviation from an evolutionary approach to build on fielded 5GFA so there are down sides to that as well.
 
But why such a gigantic delta wing, so far aft on the fuselage (that makes guessing CG location really tricky)?

More seriously, there has to be some camber variation for that, either via effector or mechanically. It can only be the logical outcome for such a large flat wing surface (with no clear Elevons/flaperons).

You might want to refer to the CRANE thread for more information related to effectors.

Anyhow, I guess Canadian would now feel irresistibly drawn by this new endeavor:

And just to add to that....and hopefully completely bury the stupid Telegraph story...I think this conclusively puts it to bed...

""It's important for me to put on record just how important a programme this is," Starmer said at the opening day of the Farnborough Airshow on Monday."

"It is an important programme and I know that people in the room will want to hear me say that," he said.
"The defence secretary is holding a ministerial level meeting (...) in relation to this because of the significant benefits here in this country."

"Obviously the most important part of a 6th gen is that looks cool and futuristic" I want to nice, but like what? Like 90% of what makes a 6th gen a 6th gen is the internals and size, not the LO shaping of the air frame. Either way we've basically known the best airfoils for LO construction since the late 80s/90s, so it being vaguely reminiscent of a 5th gen proposal means nothing when LO construction has barely shifted since those concepts.
And, for Japan, it would be like coming full circle if this design is adopted.
It wouldn't be at all. It wasn't that Japan thought the LM F-X concept was bad. It's that they were absolutely sick and tired of any joint fighter development with LM after they screwed over the F-2 program. Japan could adopt a 1:1 exact copy of that proposal with Italy and Britain and their original goal would be achieved by simply not having any LM execs touching the program.

I think its too early to say that there will be no fundamental advancement in RF and IR signature management and other things to significantly alter the design of next gen fighters away from what we've seen from current 5GFA's. Not unless you see what others, particularly, the US NGAD OE's put out in terms of their flying demonstrators and other proposals. They could certainly look a whole lot different from F-22/F-35 and/or planned offshoots of those designs.
 
This could turn into a real cluster. Just design and develop your own aircraft, it's bad enough with a tri-service aircraft or missile (i.e. F-35), gets worse with a tri-nation program (i.e. Eurofighter) because everyone wants and needs something a little different then the program takes forever.

The post above you says that all 3 have identical requirements, so that isn't an issue.

There's zero chance that the British, Japanese or Italians will ever make a 6th gen on their own. It's simply too expensive and they'd never order the number needed to make the project make any economic sense. They'd be better off just buying more F-35s.

What the GCAP has going for it is that all the partners have more or less want the same aircraft and each have something to add to the program.

Most of that stuff will come through material science rather than radical airfoil changes. This GCAP model is already different enough from the LM concept that any changes that could be made from that core design probably have been already implemented.

As stated by Gareth, these changes to the wing shape have more to do with payload and range since these bigger wings can accommodate bigger fuel tanks or perhaps IWBs in the wings.

I did not say all 3 have identical requirements, I said "because everyone wants and needs something a little different", does not sound like identical to me.

I disagree with that, the F-35 does not fill the same niche that GCAP does, nor does it bring the same industrial benefits. The F-35 would be inferior in terms of size, weight, range and growth potential. Not investing in GCAP would be more or less a death sentence for the military aviation industries of the member states, in addition to the fact that engineering knowledge can be a massive political and economic bargaining chip.

Of all the 6th Gen fighter projects, GCAP is the one which seems to be the most realistic in terms of outlook. NGAD and F/A-XX are being scaled back due to overambitious requirements and cost growth, and SCAF is yet to have a deal worked out yet.

Well they are....and F-35 cannot deliver what they need....and given the absolute state of the F-35 programme at present might not deliver what has been promised in a reasonable timeframe...would anyone actually be shocked if Block IV still hadn't been delivered in 2035?

Tornado worked just fine. And Typhoon did as well. Because everyone wanted the same thing...look at the original requirements....

Typhoon suffered because an event happened that could not have been predicted (end of the Cold War and German re-unification)...that caused delays, but the aircraft is fulfilling its original promise of a multi-role fighter aircraft.
 
The direct head-on image is the lambda-winged previous iteration. While it is a previous version, the monochrome/blue image and the more recent three-quarter/front view all show just how broad the fuselage is in both versions. That thing's going to have some big weapons bays.

I think that by comparison, the FCAS/SCAF is going to continue to be developed with carrier compatibility in mind, driven by French requirements, which will therefore determine size, range, and weight limits. Neither is 'better' because the two can't really be seen as rivals. They have very different roles, so any talk of 'redundancy' or a merger of the programmes can be dismissed too.
