While playing around I noticed that missiles (BVRs mostly) behave quite unrealistically. I have a bad habit of flying low and slow, and this is the worst place kinematics wise for BVR combat, yet, I have little problem scoring hits. Granted, AI doesn't know how to defend with maneuver, but it is still wrong. Similarly, when I am on the receiving side, no defensive maneuver seems to help - missile will still get me. The only way is to abuse the game's engine and go below 50 meters when AI loses all means of attacking me - even with guns. Checking out the missile performance shines the light on the problem. First example, R-24R - I launch on pursuit course, while going at 0.7M at target above me and going with the same speed. Missile accelerates to 3.7M on upward swing and even gains velocity during the entire 30 or so km flight path. R-40, while checked in MRS, shows the range of 160km while launched at 2.8M from 15k meters. And the crazier ones, AIM-47 shows the range of above 1200km (!) at the speed of 14M (!) while launched from 15k meters at 3M. Both AIM-47 and R-33 have weird 240 second sustainer times. What this means is that missiles are barely energy limited, and the max effective launch is limited only by the statement in DATA file. Your kinematic performance barely matters. This turned out easy to correct. -------------- The missile performance is governed by few statements in the DATA file. Booster acceleration and booster time govern the max acceleration of missile. Acceleration is measured in Gs which are roughly 35km/h. The time says for how long the booster works. Thus, If we have acceleration at 5 and time at 10, we get 5x10x35 = 1750km/h of default acceleration - with no account of drag and launch platform velocity. Sustainer works by the same logic. Then we have subsonic and supersonic drag which determine mostly how quickly missile runs out of energy. Supersonic drag is the most relevant here of course. The obligatory tool to deal with missiles is MRS: Now, keep in mind that missile performance you find online is usually its best performance - meaning launch from good altitude at a good platform speed. For the sake of simplification, let's assume the altitude as 15k meters. You may tailor it more accurately by ceiling of known aircraft, but I keep it at 15k. The platform speed will be close to max M number of given aircraft or aggregate of various aircraft using a given missile. As an example, I show the process for R-40 missile as it is very dependent on launch platform kinematic state. First we have to set up the launch state. MSR has no altitude setting but it could be st by IAS/TAS ratio. For 15k meters it will be around 0.6. MiG-25 will launch it at 2.8M. The speed of sound at 15k is around 1060km/h. Thus, 2.8x1060=2968km/h. Then we convert it to m/s - the factor for this is 3.6. So, 2968/3.6=~824m/s. We input this into the init speed. Weight and diameter of missile could be picked from DATA file. Thus, 475kg and 0.31m. Now we had to deal with the booster and sustainer. R-40 has no sustainer, so both values at 0. For R-40 we are lucky and we know the default acceleration - around 2.2M and the max speed - around 4.5M. We pick the first value. 2.2Mx1060km/h=2332km/h. Then we divide the given speed at G value - 2332/35=~67. Let's say we give it a 4 second booster - so 67/4=16.75. This way, we have booster acceleration at 16.75 and booster time at 4. We press SIMULATE and get 300km range (statement Length) with max velocity 1455m/s (~4.9M). Speed is almost there, but the range is out of whack. We forgot about the drag. Now, we experimentally adjust the drag to bring missile range close to its real value. For R-40 this should be around 50-60km. Drag has two windows, first is subsonic, second is supersonic. Second is the most important here, keep the first below it. Input 0.6 for subsonic and 1.2 for supersonic. This gives us 56km range and drops velocity to 1353m/s (4.5M). This looks really good. Check out the energy loss curve too. Now we can check how missile will perform at subpar kinematic state of the platform. Set IAS/TAS to 0.95 and init speed to 350 (this is going at 1M at 2k meters). We get pitiful 11km range and 845m/s (2.4M) velocity. This is close to how the missile should perform at such launch parameters. I strongly recommend to extend the duration in DATA file too, make it so missile lives longer --- R-40 was easy as we know both default and max speed, as well as the parameters of launch platform (MiG-25 and MiG-31 behave similarly). What about missile when we know only the max speed? Sparrow for example, it has max speed of 4M. But if we use 4M for booster calculation, we get values far above 4M. Take the max missile speed at retract 70-80% of the optimal speed of launch platform from it. Assume we mind Phantom launching from 2M, so we set up 4M-1.5M=2.5M of default acceleration. Let's make the same tuning for AIM-7M Speed is almost here, but range is not enough. As we know, AIM-7M had sustainer, so we can use it here to extend the range. Sustainer acceleration at 4 and duration at 10. I also drop booster to 17 And once again, subpar kinematic state check: ---- What this does in-game is that your kinematic performance now matters. If you want extended engagement ranges, you had to go higher and faster. And missiles now actually lose energy. I am not sure if missiles in-game lose energy during maneuvering (hard to check since AI doesn't defend) but I hope so. ---- Now, this doesn't quite apply to lofted missiles like AIM-54 since they have very different flight profile, and this MSR has no loft settings. I guess you can set them up to have reduced range and velocity and then check in-game if they perform correct while being lofted. Likewise, I currently don't know how this tool could be used to tune SAMs since their flight profile is radically different.

not necessarily a no. just not a yes my guess however, is that the labels apply to targetable vehicles, while AAMs/SAMs are considered ammo and thus dont get labels

I know , every modern destroyer can crush her ... , but what about miss election ? She is kurwa sexy .

Can you hum a few bars? I might be able to recognize it that way.

Launching the CAG..

hittin teh IP, fire up the cameras where'd everybody go?

Good Morning Ivan.... черт!

is that airbase supposed to be smoking like that? i mean some things smoke naturally but....

uploaded the updated A-6A Late Intruder 1.0.1

MiG-21MF with Souli.😎

Jammin Voodoos over Europe. One of my favorite what-ifs because I really enjoy SEAD/DEAD missions. With only two pylons available for Shrikes it's sure a case of pick the right targets! 179th TFS EF-101D Detachment flying out of Hahn AB on the first day of WW3 in 1986. Who would have thought some second lieutenant in a rickety thirty year old aircraft would be one of the first to fly across the Inner German Border at the start of the war?

happy hump day everyone

Cap over Korea...... Let's go see if the Migs will come out and tangle They did.. Bad Idea... Back to the boat. ...

Sorry for taking so long for the update; this one is coming soon the A-6A late improved.
