bies Posted March 27, 2020 Posted March 27, 2020 (edited) Both configuration of Hornet: 2 x AIM9 + 6 x AIM120 on single racks = 455kts TAS / 1.0Ma max speed (track attached) 2 x AIM9 + 10 x AIM120 on double racks = 455kts TAS / 1.0Ma max speed (track attached) Identical speed thus supersonic drag. (default weather, no wind, 20000 ft standard day Cauasus in this case) Why? Are 4 additional AMRAAMs dragless? Not exactly. Because single racks have massively bigger drag than double racks in DCS at this moment. Clean config + 4 single empty racks = 517kts TAS / 1.14Ma (track attached) Clean config + 4 double empty racks = 553kts TAS / 1.22Ma (track attached) Which is impossible IRL for double rack to be less draggy because double rack is the same LAU-115 single rack with additional 2 sub racks on it.

Auranis Posted June 26, 2020 Posted June 26, 2020 Just want to bump this. Did my own tests recently and the results seem to match OP. I can post track files if requested. I don't know how the drag modeling system is designed under the hood, but I do find it interesting that the single-racked versions of the LAU-115 for the AIM-120 and AIM-7M are named "LAU-115" in the mission editor, while the equivalent for single-racked Sidewinders and other Sparrow variants is named "LAU-115C". Maybe that has something to do with it?
