Mitsubishi F-15J

I wish the original engines are on their last legs and the F-15Js get upgraded engines (-229s), though I’m sure they still have plenty of life left, not to mention I’m not even sure if the -229s are drop-in replacements.

Can’t put -229’s on air superiority eagles

What’s the reason? Small air intakes? Too heavy?

It’s not impossible, but it does need extensive modification since the F100-229 or even the F110-129 engines are larger than the F100-220s on the F-15s.

It’d be nice to see it done anyways, especially the F110-IHI-129 already produced by IHI for the F-2, but it might not be seen as necessary enough to justify the cost of modifying such a large part of the fuselage.

External diameter is the same for all of them, GE-129 is allegedly shorter which could cause the intake area and programming to change.

Hmm… I tried to look where the information of the size difference came from and there just doesn’t seem to be a source at all.

They require a common engine bay only found on later build F-15’s like the E, K, SG, SA, S, QA, and EX due to some size issue or other limit.

Just clarifying, BOL is not possible on any Eagles except for US ones, due to them being the only ones to receive the Mods for ALE-58 usage. It is not just as simple as if it uses LAU-128 it is BOL compatible, it requires additional wiring to be done.

The only export Eagles that might be BOL compatible are the ones Israel bought secondhand a couple of years ago from the USAF but it would be on tail number basis and none of you would have access to the documentation showing which TCTOs those aircraft had done.

Can this plane detect an AESA radar lock?

All modern rwrs can detect aesa locks in game. So yes this plane can detect aesa lock

I wish the plane had the right radar warning reciever.

So. Right now it has the J/APR-4, which is the exact same as the APR-4 in game, issue:

  1. The J/APR-4 is NOT an APR-4, at all.
  2. The F-15J(M) does NOT even use the J/APR-4, it uses the J/APR-4B, which is an upgrade of the upgraded J/APR-4A.

So basically, yeah it should be better then the APR-4, considering its a twice upgraded version of a newer RWR.

Is there any difference in the rwrs? Like band coverage or elevation coverage?

Nothing known lol, but gaijin just treats newer = better for RWRs so it doesnt really matter.

@Xeno_quaza
The other thread got closed so do you know if the F15J(M) is missing its rear MAWS for Fox2 and whether this is a bug or devs’ decision?

Yes it should have it and is a bug that it doesnt, but a correction from that thread. Its a doppler based system not an IR one. Japan didnt start developing IR / UV based MAWS until 2014~

So the F15JM we have in game is MAWS for fox1 and fox3 from behind only? And the newer MAWS is rear for fox 2 only or all?

MAWS works for all approaching objects from the read hemisphere, even things like rockets. (And as its also listed more generally as an approach alert receiver, even hostile fighters.)

That being said, no, it doesnt have sensor fusion in the model we have in game, although there is a variant with an imrpoved RWR that does get sensor fusion for it, which im actually working on writing a suggestion for.

Ok thanks for clearing things up.

Is this for the F15J super interceptor or is there another variant that you’re talking about?

Im referring to the “F-15J J-MSIP Modernization Type 2 (Improved Self-Defense Capability)” as its fully upgrade title would be, or just F-15 Modernized (Revised) as something closer to its actual name

Basically, it was a rewrite of the Type 2 modernization applied to certain lot C-14+ aircraft, containing an IEWS (Integratted electronic warfare system), which has features like jaming, sensor fusion, increased rwr performance.

Visually distinct by a bump behind the engine inlets.
