It is not a magical plane, if you put 15G on one wing it will rip
The AIM-7F/M now have their self-destruct timer raised from 5 seconds to 20 seconds.
Spoiler
Some other missiles also had it raised to 15 - 20 seconds.

Is there any way to help me fix the roll rate when using the mouse? The F15 has a high-speed roll feel similar to the Mig29, but there’s something on the Mig29 that prevents me from rolling too much when using the mouse at supersonic speeds.
Roll rate is AoA and speed dependent, at very low AoA it is faster than the F-16, but as AoA increases the roll rate decreases, similar to the MiG 29. At supersonic speeds, the roll is also limited. If it is different in RB, it should be corrected.
it similar, but still too much for f15 wing
The wings of the F15 will break immediately if rolls, pulls, and rudder inputs are applied at supersonic speeds. I wonder if this is indeed the case, or if the wings will only deform before breaking completely. As far as I know, the wings of the F15A are quite flexible.

The structure of the plane won’t just change because there is or isn’t OWS. Its ~9G+1.5x. An F-15A won’t just fail above 11G because its lacking OWS and another with the same structure will be able to pull 13.5G just because it has OWS. Its just operational limit, not structural. You can see that even without OWS F15As would be able to handle +7.33G without issue as it was all retrofitted to all planes
when it was introduced in 1980.

Is there anyone who knows if HDN Mode is High or Low PRF? Because PD HDN is good for locking targets coming towards you because it has more range, but it has blind speeds (So Low PRF if I understood correctly). High PRF is better for all aspect PD locks but loses range because the higher frequencies so this looks like the SRC PD mode. Is this always the same in WT?
Also in the datamines this was included:

This made me think I am wrong about PD HDN being Low PRF but it could also be a mistake or being the Medium PRF mode.
Anyway if anyone could clarify I would be happy :)
Can anyone give me a quick rundown which radar modes of the F-15 is best for which situation?
PD HDN is HPRF. HPRF puts more energy on target and therefore has increased range, not decreased range. The issue with HPRF is its range return is ambiguous, but its velocity return is accurate, which is why you also have PDV modes.

We are not arguing about OWS modernization, that’s what I’m writing too.
I mean, f15s have pulled 15+Gs without the wings ripping off, normally with slight deformation to the wings but not total failure
This is often claimed but in truth the peak milisecond overloads calculated for certain sections of the airframe are not the total normal load factor across the entire airframe. Peak G forces applied are generally never more than ~12G’s with the aircraft staying in one piece.

The correction is simple, give the F-15 an audible warning, that is simply put an OWS system in the game to the F-15.
15G on symmetrical load on both wings and it sustained damage.
You can do the same in game at low weights.
But when you roll, pull and yank rudder at supersonic you are pulling assymetrical loads with your wings, making so that one wing is being overloaded with all the g load.
Wings sustain way less asymmetrical loads so the wing rips.
Solution is nerfing the rollrate at high speed or nerfing the pull at high speeds on instructor.
The asymmetric limitation is about 5.7 G, it’s for all US aircraft because it’s the standard. Except maybe the F-22.
Have you even played the F-15? It does have the audible warning for Gs
No. I don’t. If he has OWS and a good FM, then ideally War Thunder should say that the problem is on the player’s side. If he doesn’t have a good FM then he should say when it will be fixed.
The problem is not the FM. The problem is the instructor/mouse aim. The instructor will flutter all of the flight controls even just rolling back to level. I have yet to be able to get the F-15 to rip in Sim once the external wing tanks are dumped, even slamming the rudders and stick around trying to get it to break. I would have better data on with the Wing tanks installed, but I hardly use them.

My point is that structural limit isn’t the limit that instantly destroys the plane, even 1.5x that. The structural design limit is the load at which the fatigue life is infinite, or in the case of aluminum, high enough that the engineers aren’t worried about it for the life of the airframe(probably hundreds of thousands or millions of cycles at that stress). If you exceed that limit you risk reducing the life of the airframe, depending on how much over and for how many cycles, not instant death.
Even if you assume 1.5x the structural limit would cause yield(a very poor assumption judging from the fatigue curves) you’re still going to be in the hundreds if not thousands of cycles before failure range, aluminum is not brittle like modeled in game. That’s why planes IRL survive Over-G and why it requires part replacement, because that part now has reduced fatigue life by an unknown amount. It’s also why structural failures generally happen on high hour airframes(read about the f-15 structural failures due to incorrect longeron here: PICTURES: Manufacturing defects caused cracks that downed USAF F-15 | News | Flight Global , it took 25 years before enough fatigue cracking occurred for a faulty part to fail during a high G maneuver). Fatigue cracking is your enemy in airplanes not ultimate tensile strength.
My point is no 4th gen aircraft from any nation should be experiencing wing rips from over-G unless it’s insanely high, It’s not realistic and it’s not fun. Engineers think of this stuff.
Chart is for 6061, but should be a similar shape just shifted to higher strengths for an aircraft aluminum like 7074, 2024, or whatever custom magic mix the f-15 is made from.
Note: This all applies to a fresh airframe, I’m ok with ripping before unlocking the “airframe restoration” modification due to potential existing fatigue cracks, as that’s at least grounded in some realism.
