Isn’t an adaptive cycle engine planned for the Tempest? If so, it can’t be the EJ2xx or a derivative of it because implementing an adaptive cycle would require a complete redesign of nearly everything. And putting a 74 cm diameter engine into a giant 18 tons fighter doesn’t make quite sense (The F119 and F135 have around 100 to 110 cm diameter at the fan inlet AFAIK).

Adaptive Cycle isn’t confirmed but given Tempest is designed to fullfill a purpose similar to the B-21 in US service but with fighter utility it would be so so so incredibly stupid of them not to opt for it, its also well within RR’s capabilities. They aren’t going to achieve the range figures of a bomber without making a bomber unless they go for adaptive cycle.
The only thing we actually know about the engine is that its power generation is planned to be much much higher than even EJ200. Essentially bringing the naval concept of Power Integrated Propulsion and shoehorning it into fighters to allow for very very high levels of AI integration, internal computing, EW and eventually directed energy weaponry (likely in a hardkill APS role).

On the note of why it would probably be an EJ2xx derivative on the demonstrator. The first thing is that the demonstrator will not be indicative of the final aircraft, likely it will be smaller but still larger than Eurofighter, probably around F-22 sized compared to the F-111 size of Tempests final airframe.
The engine selected will be an available, suitable and most importantly low risk engine, the RR engine for Tempest won’t be that, its not available, and its not low risk at this stage. Consider that DA.1 and DA.2 flew with RB.199s because EJ200s weren’t ready yet, but the engine had already been bench tested, they could even have used the XG-40 that EJ200 was based on. This is a step even further, because RR had an engine (the Tempest equiv of XG-40) and now Japan and MHI is in they’re trying to see what they can change to make it into the Tempest equiv of EJ200.
The demonstrator might eventually get a prototype of the adaptive cycle but I think its more likely the demonstrator will test the airframe’s basic design and mechanisms like the weapons bay, and then the prototype will be the first with the new engine. The prototype being an airframe actually indicative of the final design of Tempest (the equivalent of DA.1/DA.2)

Reading only that, the new engine will have to have a completly different core. I would be surprised if there would be any similarities between the planned Tempest engine and the EJ2xx.
I would assume they are using the IHI XF9 as a base for the Tempests engine or even a modified version of it. It ticks most of the requirement boxes (for example 180 kW generator output) except for the variable cycle.

There are no real similarities implied, but naturally knowledge is implemented and RR’s ‘style’ is kept, we know its a clean sheet engine. RR already had one developed before GCAP became a partnered thing. Obviously now joining forces with MHI means joining forces with another very talented engine manufacturer with their own knowledge and IP on advanced concepts. So now I suspect they will be deciding whether to implement those advanced concepts into the RR design, or whether to start clean sheet and try and take the strengths of the RR engine, and knowledge from MHI to make a completely new engine which will take longer, but joined forces makes that still a feasible option whilst retaining the 2035 IOC date.
As I said I think it depends on how far and how good this RR EJ200 successor is. If its got variable cycle that is probably by far the hardest part of this. Energy generation coupled to turbine engines RR has been doing for decades and literally supplies every western nation with this capability on its naval applications.
Given this I expect the engine they developed to be more or less class leading and might even feature a higher generator output.
All of these are guesses though, we very much don’t know anything of value about this RR engine or about any planned characteristics of Tempest bar F-OFF huge.
You shouldn’t compare gasturbines only used for power generation with aviation gasturbines which have to deliver thrust, electrical power, hydraulic power and bleed-air at the same time to varying degrees. The core has to support all these things at once without impacting any of these to a certain degree even if the consumption varies strongly. For example if you vary the thrust you don’t want to loose bleed air, electrical or hydraulic power at all but don’t want the engine to react slow or not strong enough. It’s completly different to normal power generation.

I’m aware they aren’t the same or even comparable, but RR has said that’s where the majority of new innovations are being applied from on the new engine compared to the already great energy generation of EJ200.
So because i am only 3 planes off of researching it what should i be expecting out of the Italian F-2000?
(Asking here because this is the only active typhoon thread and it looks similar enough to the british one anyways.)
Also man the F-104S is painful to play…
Good FM, weak missiles and an annoying fight with the radar
and BOL sucks at the moment
On 70%ish fuel, you can pitch your nose up around 40 degrees, climb almost 300m/s and still be gaining a little bit of speed.
The rest is up to your extrapolation.
Ironically there is exactly no source/number which states the energy generation of the EJ200. We have no idea how much electrical power it can generate.

Are we expecting any type of fixes for the winter update?
It should be, but I fear fixing of Typhoon would be belated to Spring 2026 (as along with the releasing of AESA Typhoon), just like how Russia still haven’t got their top tier aircraft while Britain and France finally have their own Eurocanards.
Because the most likely addition this Winter 2025 update would be J-10C and Gripen E, because China and Sweden never got their properly Gen 4.5 Aircraft.
i see a Su-35 and I see F-15FM fixes and Amber racks for 12 120s and IRST POD
I see no changes to Typhoon, Gaijin think it’s fine.
Maybe HOSBO is rolled out to all Typhoons
No, but I’m expecting more issues to come up.
as of now, my best strategy to play Typhoon is to literally think Typhoon is a glorified Starfighter + F-15E.
Always carrying double drop tank as Typhoon chug very much fuel. And try to consistently diving and target every enemies that are head on to you because either way they would chaff away.
I agree Typhoon have very mid missile kit, like, AIM-120 is very jack-off-all-trade missiles that master of none, I love how R-77-1 either by its quantities or its raw power on straight line.
People now are know how chaff works, AIM-120 really needs a rework to stay competitive.
That is what the EFT needs more than anything.
Parts overhauled.
BOL Overhaul
Aim-9M Overhaul
Aim-120 Overhaul
PIRATE Overhaul
CAPTOR-M Overhaul
And if we got ECM too… Would be pretty good. Though I still think postponing it getting AESA because “reasons” when the Rafale has had AESA for an entire year now. Is just a bit silly

Well, because technically Britain and others gets “New Toy” while China and Sweden barely got any new toy throughout the year, and so does the Russian, and US at the worst, only to receive Gen 4.5 in current Fall 2025 update. Being a really mid aircraft is just in the end mid.
Yes Typhoon had a MAW, but so does J-11B, and they’re sitting at 13.7.
And there’s South African Gripen that are more fun to play because its HOBS Power is pretty great (literally MICA Jr.) and also sitting at 13.7.
But there’s also F-15C Golden Eagle,but I think the main power of it is Full BOL, even in the end is BOL, 4 BOL is better than 2 BOL. I consistently Chaff Dumping in Gripen, and it works really great playing defensively with it.
Not even getting a UV tint update at the same time Rafale got it is wild.
And there’s still squished HUD lmao

This is still no excuse for BOL to be artificially nerfed through the floor. Especially given how many aircraft are suffering at the moment due to those nerfs.
Its a bit like removing IRCCM from the Magic II because the Rafale is doing well. I dont think the earlier Mirages would be fine.
Hu? Whats that got to do with the price of bread?
So? Because Britain has the Gripen C with okay short range ARH, the Typhoon for Britain, Germany and Italy need to be nerfed?
Hu?
So everyoen can get AESA but Britain, Germany and Italy cant because? We must be last?
