I think the closest to study level for a military fast jet for MSFS is the Just Flight Hawk. I’m sure you are aware of the sim with a large collection of study level military aircraft modules.
I doubt you’ll ever get what you’re asking for. Too many of the systems on newer models are still classified, and precious few people have the kind of access required on the older models. You’d probably have to find one owned by a private individual that’s willing to let the dev spend time “up close and personal” with the plane, and that’s not likely to be anything newer than Korean War era.
I’m very intrigued to see what the Heatblur one is like but I got the impression that Heatblur is supplying the visuals and Indiafoxtecho is making it work in the sim.
I like their products but they’re not known for exhaustive fidelity.
If you really want a study level fighter plane, then try the Falcon 4.0 Allied Force. It’s an Windows stand-alone oldie, but all weapon systems are painstakely modelled.
I have DCS for my fighterjet adventures… Only reasons i can think off to fly a fighter in msfs is to go low and fast, “escort” another player or do some aerobatics…
For the shooting and hunting stuff you really need another sim/game
anything you can do in MSFS you can do in the “other sim” as well plus the added combat aspects. For “study level” aircraft the other game is the only option.
I liked the VRS Superbug in FS9 and FSX (later with TacPack). But once I started using DCS, I never felt the urge again to simulate military flights in a civilian flight sim.
Since then, I’ve always used XP, P3D and now MSFS beside DCS. Right now, with some interesting new realeses (and some more pending), I’m more biased towards DCS. I really enjoy its fluid flight model and its graphics, and if you want to simulate a fighter aircraft in its entirety, there’s no way around this sim (in my opinion).
