The AGM-154A is currently under performing its range estimate due to what appears to be a navigation bug. After release, the bomb will enter a steep descent and gain speed while oscillating slightly, before finally impacting the ground roughly 60%-70% of the way to the target if launched at or just inside max range as shown on the HUD. If launched at the very edge it's currently usable range (~35nm), it will skim to near ground level before pulling back up to a reasonable altitude and begin its terminal maneuvers. When launched well inside its currently usable range, it behaves nominally.
The AGM-154C seems unaffected
