Next Major Update - Rumor Round-Up & Discussion (Part 2)

At least research it before you say some silly stuff like that. It gets significantly better survivability and also gets what will be the best radar in the Japanese tech tree.

Also there was a huge AIM-120C-8 and AIM-120D-3 sale approved for Japan a couple months back

it might be an inert missile but it is still an AAM3 on its wing tip

Xeno knows very well what he’s talking about, as he is also a valuable and respected member of our Research Group.

Also;


  1. Thats an XF-2A
  2. The missile is an AAM-3 (IR missile)

It’s not expected, it probably will be just as inaccurate and miss as many features as others do.

The only reason it’s brought up is that it’s about a year overdue to be relevant in the state that it will likely be added, so hypotheticals about armament and good implementation are the only scenario where it’s even remotely capable as a top tier aircraft.

That being said Gaijin did hype it up for over two years, always calling it “too advanced”. So who knows, they might actually have it overperform based on whatever they seem to think it is.


It’s unknown what exactly the JSI will end up being, there’s only assumptions made from the bits of info we have so far.

Even for the airframe it isn’t certain. The F-15SR, which was an upgrade of old airframes to F-15SA standard, still included new wings and forward fuselage sections, so it does set a precedent of being possible.

So I think it’s best we wait a couple more years until it actually exists.

what is the difference?
is it just a prototype?

my bad i always switch the japanese missiles up,
i corrected it in my message

“at least research it before you say BS” My dude i literally have read the budget and acquisition papers for the JSI, have you? The D-3s haven’t been fully delivered yet (a few were for testing, but not that many). Also, i’m specifically talking about in terms of warthunder, I know irl EPAWSS and it’s AESA are considerable upgrades to survivability (although not as much as you may think, the J(M) already had one of the most advanced defensive suites of any F-15). However the benefits you’ll see from it are not really things modeled in game.

Its a Prototype and ADTW (test wing) at the same time. Besides that; he was talking about a in Development variant of the F-15J, the mention of the F-2 was unrelated to armament options.

so it is similar to the WTD61 stuff for germany, good to know

Mb i didnt follow the whole conversation

Probably quite a bit more of test aircraft than what WTD61 is known for, but yes that kinda hits the point.

Yeah, by the time F-15JSI is done this really will be the least of our concerns.

I think the main thing holding it back is that (at least from what’s known so far) missiles will still be limited to 8 in total, which isn’t exactly F-15EX level.
There’s also no info on potential flight performance upgrades like new engines. Even if any denial seems to also be speculation, that might hold it back more.

Though again I think this is a topic that shouldn’t really be “Next Major Update” relevant until we at least have the details of the final JSI

That’s enough to be added. And EPAWSS doesn’t even need ECM modeled for it to be an upgrade, EPAWSS adds new CM dispensers (total 360 vs 240) at least on every other F-15 that has it. And should be some RWR improvement.

Saying its going to be worse than the JM is just not really true

This would be the same issue that the F-15C had – new engines simply did not fit the airframe.

The F-15E uses the PW-229 (same engine from the F-16C Block 52), and the F-15EX uses the GE-129 (same engine from the F-16C Block 50). Those fit in E/EX airframes, but not in C/J airframes to my knowledge.

Makes me really wish the US had gone with the F-15CX, but oh well, the EX will do just fine.

The 2019 DSCA paper about it doesn’t say anything about airframe changes

Or would be enough, if the JSI was finished. As it stands there is no F-15JSI, so there sure won’t be one in War Thunder no matter what weapons it would carry.

But what @Xeno_quaza said about how the JSI would be worse than the JM still isn’t true. Of course this is looking to future when JSI is at least flying or made

They might mean tier-for-tier.

The JSI would be much closer in BR to vehicles like the F-15EX, Su-35S, later Rafales, and later Eurofighters.

Meanwhile the F-15J(M) would sit at a much lower BR with planes actually competitive with it (hopefully).

It doesn’t have to be the same BR. And considering that DSCA paper says nothing about engine changes either (which are pretty significant) I don’t think that’s happening either

The increase in CM amount is not part of EPAWSS, all it does is swap the AN/ALE-45s for 47s, which do not by themselves have a higher amount of CMs. The difference in dispenser is mainly for use with defensive sensor fusion, with automatic deploying of specific countermeasures depending on threat. The F-15J(M) already has similar functionalities though, although not fully on the specific airframe in game.

The RWR coverage is honestly the only part of EPAWSS that would be noticable in game, being a full 360 degrees. Although we do not actually know how much better this would be then it’s current one. The F-15J/J(M) have a better RWR irl then their C equivelents, although the exact performance figures are classified.

They put extra ALE-47 as part of the EPAWSS

Personally, without any more information from Gaijin, my expectations for the F-2 are simply:

  • Rafale like decent radar with good TWS
  • 4x AAM-3 and 4x AAM-4 (maybe AAM-4B)
  • F-16AJ flight performance or better (with AoA limiter override or the opposite where it barely pulls AoA because it can actually turn tightly and efficiently)
  • L-JDAMs with Sniper pod

Bonus extra things would be:

  • Best in class radar in-game (at least compared to the aircraft currently in game)
  • 4x AAM-3 + 6x AAM-4 (maybe AAM-4B)
  • Significantly better flight performance compared to AJ, not quite EFT/Rafale, but close enough that fuel loads and skill will make it an even fight (honestly the least likeliest thing I expect)
  • 4x or 6x ASMs that can be used with sniper pod as basically AGM missiles like the Rafale’s HAMMERs
  • RWR coverage into the K band and maybe further so it can detect Pantsir and any other future SPAA launching at them (bonus if it has 360 degree coverage, but AFAIK it does not)
