The input angle of Harpoon missile has a large deviation.

When the harpoon missile sets the azimuth of the target, the missile will deviate greatly after a long flight distance. Always flying by the target, what should I do?

Could it be this?

 

Known issues:

AGM-84D “Harpoon” in multiplayer flies with wrong trajectory

Could it be this?

 

No, single-player games.

They said something about the first harpoon tracking, but in order to fire a second you have to reset tgt data. I do this by drselecting the harpoon then reselecting.

What can I do specifically?

[Pheonix0869]

Fire your first harpoon, then on the DDI with your stores page, deselect (unbox) the HPD store. Then select the HPD again. At this point, reenter FLT and UFC parameters, setup your turn point, and release the weapon. Rinse and repeat.

In my case, a simple STEP was enough to correctly program all of them. No need to deselect HPD and select it again

I also found that they are “smart”. In that if you target a blue vessel it flies right on by. Run the same mission after turning that same ship to red and bingo.
