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~
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.
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.
Also with the F-15DJ it also allows for future intergration and implementation of dedicated ECM and Jamming equipment.
such as seen the secondary role of the F-15DJ’s being interdiction escort.
Not much other then boeing delaying things as usual…a little bird said Japan might just out right buy F-15EXs as a stop gap measure but thats all just hearsay for now…
They should indeed buy a few, considering how many munitions those beasts can carry, they could even ask for some extra anti ship treats and all, not to mention they’d be new airframes with a lot more longevity and tech optimizations, I’d imagine modifying the JMs isn’t cheap either and won’t last as long
