Experienced the same as the OP with the given scene, 64 out of 64 falling short (quite a bit short). Same unit type firing at max range as well with AGM-158C's turns up the same, 64 of 64 falling short when fired near max range. The fuel is there, appears to be consumed at the rate it should be. Measuring distance traveled per time-frame (1 minute should be ~10nm at 600kts) though it's falling significantly short most minutes varying between ~3.x and 10. Then I remembered the terrain. Pitch is accounted for and I think grd speed not airspeed is used for movement distance with terrain following AGMs. You can see the Gnd Speed changing(often) over that terrain, but also to extremes when the pitch is extreme, (gui GndSpeed at times drops as low as 100kts)? Seems like WAD to model realism. I wonder if anything's changed in last couple months such that maybe it's more noticeable than perhaps it used to be, or it's just the topography. But this can cause an issue with the mission planner/autotargeting because it's going to think the AGM's are in range doing a line calculation and not account for terrain it doesn't know about (idt anyway). This can cause some users confusion as well, such that if say 95% of the path is over water or flat land, you'll basically get full range, but if you're bobbing up and down over hills and mountains it adds up. So you have to remember to factor that into planning, the more extreme and constant the bobbing the more you lose. It's realistic but it does cause issues like with your sample as other system use the full range for release guidance and prelaunch distance checks vs what will be the actual distance over a give path that may be taken. TLDR: Terrain following and the related ground-speed changes are stealing your max-distance, and the mission planner/auto targeting can't account for the terrain. Try a mission WRA setting on the munitions for like 10-15% less than max range if the likely paths include long mountain ranges,if you do the mission planner will adjust the release point.
