Stealth in BMS

So question has the avionics F4 code been rebuilt allowing for new air craft systems?
NOT… NOR OTHER “TOYS”
JUST “Stealth in BMS”

This was my… ehh proposal…
There is a man here around, done a degree Thesis for real-time calculating RCS on pc simulators. Not much time to write everything but you can dig up and find out how and outcomes. He used detailed 3D models (created on 3dsm etc. ) for F-16, F-4, F-35 and using modified SW was abled (and proved in the field) that RCS calcs for -16 and -4 was >90% accurate, dynamically from any angle. So next was the -35, so there are some estimation numbers somewhere…
This is the proper way to do it here too, starting from detailed 3D models, aircraft, stores, tanks, weapons, add colors (Have Glass etc. options), then real time calc similarly the dynamic numbers that would push this title fw.
Not the exact doc but just a clue to search.

Anyway, what we discuss here is more venting than everything else because we can whine for hours including myself, it will never bring a dev to move because basics of BMS is that dev do what they want to !

Point is how it works for stealth fighters? When airframe is so much optimized to reduce RCS even row of few rivets or something protruding from the surface could increase RCS for +10% .
So calculating RCS from a 3D model in such cases may be way off. -

So calculating RCS from a 3D model in such cases may be way off.Also using the 3D model shape simply neglect the effect of the engine following the intake. The radar antenna which act a reflector for a radar which scans any fighter etc.
(This is why built in the radar in tilted to EVERY stealth plane. B-2, F-35, F-22 it does not matter. Even it reduces the range of the radar.) -
@molnibalage
I guess here’s talk about models not used in game but much more detailed.
I guess then it could work for 4th gen fighters. All in all all all of the current fighters were designed using computer modelling. Yet it still might be not enough for stealthy design where every minor detail matters. -

“How” is a stealthy design made? And “Who” may assure that all things have been made correctly? We are talking about strictly classified data/elements here, no nuts.
See if anyone can be able to know something about some “sexy” aspects of the Tornado or the Eurofighter (to quote the very frist examples coming to mind, not that this concept may be not true for any other war plane, of course).My humble opinion here.
With best regards.

Just an idea… how about making it an option in the game settings (maybe in the “realism” area) so you can choose whether you would want aircraft to a) use close-to-real-life stealth parameters (100%) or b) make them detectable as if they would not have any stealth material at all (0%)? For playability purposes, maybe intermediate levels of 50% or 33%/66% in between might be helpful as well? This way, everybody could choose to their own liking.

That is not the same as RCS being the only factor to decide if you can be detected IRL, but for a BMS approximation it can lead to a more fair combat outcome IMO. -
Good Day, All
First, let me say that these are my opinions, and not necessarily the Mafia’s…@Rouge1512 said in Stealth in BMS:
I’m even afraid that this evolution will “kill” BMS, unless it evolves into a 5th generation aircraft simulator. But if the increase of the invisible threat remains only related to your theaters and that it doesn’t engage the whole evolution of the game …
And I write this knowing how to kill in BVR any invisible plane, at least in BMS 4.36.1 …Your feedback was what I was hoping for, both on the original question (stealth in OFMKTO?) and the larger question of stealth in BMS. I’m starting this post with this from Rouge because this is a real concern. I just want to make it very clear we do NOT want to make this a Fifth Gen Sim.
BTW, Rouge, please share your techniques for beating stealth in 4.36. That is a factor. People reach out to me saying they’re tired of getting hosed by planes they can’t even lock on radar.
Our view is very much like Radium’s. We want what I call Old, Middle, and New School in BMS. Old being 60’s-70’s with Sparrows and such, Middle with pre-stealth jets, and New with all the 4th and 5th Gen bells and whistles. And , the beauty of BMS is that we can provide that. Even if we put realistic RCS values in , anyone with a passing knowledge of the Editor or Mission Commander can simply change or remove the stealth jets. Chuckles already makes X-Plane, and a Fifth Gen-inclusive OFMKTO is possible, as we’re discussing here.
There are a lot of things in all your posts I want to discuss, but just so this post doesn’t become a book, there are a couple of specifics I’d like to address.
ReaperDog, you write " as for the rest of the aircraft mods add on’s well they are just toys and additional’s to the sim that add fun or the added function of dissimilar aircraft training. The focus however should be to keep the history of the sim, why Frankenstein it… is my take anyway.". That is your view and we respect it, but we emphatically do not share it. Let’s take the Hornet, for instance. It can be flown and fought just as well as the Viper. The Hornet and the other Other Jets are not toys , fakes, or Frankenjets to us, and we will continue to develop them. But, I bring this up to make a real point. We know ,or at least assume, that most of the BMS Community flies the Viper. Knowing that, we very strongly want to honor that and the Viper. It’s Legacy is secure with us. I mention that the feeling I get is that a lot of the no voters are doing so to not “ruin” the Viper.
The second point for now is can we do this? Molni, you in particular make a strong case that it can’t be modeled. I agree with you in technical terms. We can’t make AESA, and all that. We may not even be able to bring 100% total Stealth to BMS, at least not without hard code access.
But, I have to disagree with you in a way because in effect it HAS been modeled. I , by myself( so blame me ), without anything like your Tech skills, changed the dynamic air to air. There is still much to learn, but here is where I’m coming from… I made a simple 2v2 TE with F-35C’s vs. J-20’s. By simply changing the 35’s RCS to a realistic(we think) value, it turned the engagement from what we have seen in 4.36 to a 10-15 mile “knife fight”.
And that, my friends, brings us back to both the original and bigger question. Where do we go from here? -

I voted no.
I thought Falcon 4 was about realism?! That was the flagship of that hobby, wasn´t it?
“Stealth” does not come alone. It is not simply open the DB editor and change a value. There are dozens of avionics properties, weapons capabilities, networking between acft, jammers modes, RWR specs, Radar types, etc…that need to be modelled together. It requires extensive code support, and above all, someone (=with c++ skills + time + endurance…yes it takes years) willing to do that. Half-baked changes in the DB to simulate modern aircraft lead to unbalanced scenarios between platforms of different eras. See what is happening now in some theaters, people flying F-16s vs J-20s vs F-22s for example. There are a lot of “gears” from the real world war machine missing in BMS, what make such scenarios, yes, a Frankstein, and strongly unbalanced and unreal.I strongly disagree with some opinions that BMS needs these changes to have a chance in the future, a kind of evolution. IL-2, for example, still simulates WWII airplanes and the player base is much larger than BMS. They will certainly never simulate the Vietnam war to “evolve”. Their evolution is in new 3D models, novel terrrains and theaters, particle system, etc. There are similarly a large amount of things to be expanded and enhanced in the current BMS , which will certainly make it even more attractive and able to simulate new aspects of air warfare.
If you guys start making changes in DB without extensive code support, our small community will be fragmented very fast, potentially hurting Falcon 4 in the long run. Think about it.

These changes would only happen in theater mods, separate from usual installs, not replace them.
Escort jammers already are half baked products in BMS.This being said, I’m sticking to what I evoked earlier and am not really impatient to see that happen.

@drtbkj said:

Indeed.
Yet, this is a false equivalence. Surely, you don’t consider the 4th gen Hornet to stand in the same example as the J-20 or F-35…?
Dude - the Hornet was available as an add-on way back in Falcon 3.0…!
Your apples are fine, but your oranges are the issue of contention…

I’m not necessarily voting no, but I do agree with this. There is so much more than just stealth that is a factor on the modern day battlefield. I’m all for expanding the database with new jets and also like the challenge to take on jets like the F-22 or the J-20 in TE’s. Adding them to a campaign though, I’m not so sure. The balance is going to be off in my opinion for the reasons mentioned above.
The F-16 is currently still being updated to give them better survivability on the modern battlefield. F-16’s are being fitted with AESA radars, tested with IRST pods and all kinds of modern toys. We don’t have any of these toys yet in BMS. So you’re basically putting modern J-20’s (for as far as that is even possible) against F-16’s with the tech of a few years ago. It was mentioned above that 4th gens do have a future alongside 5th gens and that tactics are developed that 4th gen and 5th gen fly side by side. While this is true, we cannot simulate these tactics in BMS (with the AI). We don’t have the comms and networking capabilities that the real jets have. So in my opinion you will not have an accurate representation of what that modern day battlefield will look like.
I do like to sim the F-16 like I’m flying in present day, but you are limited in this because the sim is behind the real jet in development.
-
I suppose to have errorneously clicked on the poll, with unknown result.
My opinion is that more stealth is a bit of an imbalancing change because:
1.) The public RCS values can certainly be taken with a grain of salt. There are many factors influencing the RCS of an aircraft, these values aren’t static by any means.2.) The systems modeling in BMS doesn’t reflect the state of the art of sensors, defensive systems, weapons and networking capabilities available to many 4th generation fighters that would at least improve their chances of survival. Notably increasing the number of stealth A/C would cause a massive increase in difficulty.
3.) Bear in mind that stealth is also about RF emission control, IR signatures and passive sensors and targeting capabilities.
If you opt for a more stealth fighters campaign, I would recommend a separate campaign scenario for those who like to fly such aircraft. Keep one with limited stealth for game balance reasons for those who prefer to fly none LO types.

Good Day,All
Hi, Lorik, if you meant what Rouge wrote in the J-20 thread, then I’m with you. I was just curious if there was “more to the story”
'Gorn, when I wrote that I didn’t mean I was comparing the Legacy Hornet to a J-20. I was comparing it to a Viper. So, my oranges are fine
Tiag, Tomcatter, and Scorpion. You are right there there is much to Stealth that we can’t accurately model. Heck, I still hoping someone tells us what the rcs value means in Editor. But Tiag, changing one value did cause a change in game play, as I have described. I’d like your opinion on my reasoning, and for the sake of the discussion let’s narrow the topic a bit. Let’s use the example of the F-35C vs. J-20. Neither has AESA, both have TGP’s( at least if memory serves the J-20 does) and let’s call that a “poor man’s IRST”. So, can’t they be seen as balanced in those areas. The J-20 comes “stock” with a RCS of 0.4. The change I made was to take the 35C to 0.5. My question is, was that unrealistic, or did it just balance that part of the equation?
Scorpion, you raise a point that has added to my enjoyment of this . I find I am much more aware of emission control and passive sensors when I’m in the F-35. And, btw, we have no intention of, as you say, “notably increasing the number of stealth a/c”. As previously stated , we have no desire to turn this into a Fifth Gen Sim.
All we’re talking about is making the rcs values as realistic as possible, and all we’re asking is if the Membership wants us to share that in OFMKTO -

3 different systems and design approach and the F-35 has a more mature code now after various upgrades and updates.
