cannot reproduce and missing track file AGM-84D vs Moving Target

[MTM]

Greetings all! Quick question about the Harpoon… when you have a moving ship locked on the radar and you launch a harpoon in R/BL mode, is the harpoon supposed to fly to an intercept point or does it head to the location where the ship was when it was launched? When I launch them at moving ships from 40+ miles, they often miss behind the ship.

Have you tried to give the Hapoon a longer search range by activating them earlier? This way the speed of the target has less impact.

edit: or did your Hapoon lock the target and has been "outturned"? Hard to imagine that a moving target of the size of a navy ship with 10 to 30 knots could do that.

Haven’t noticed that as one of the parameters you can change, but I’ve set SEEK to large and that seems to improve the chances of the missile finding the target. Is that what you’re referring to?

[Tom Kazansky]

Yes, that's it. IIRC large is 30 km, medium is 20 and small is 10.

I possibly found the problem, but for all I know, this might be correct behavior for the Harpoon…

I tried getting a radar lock on a ship and then launching a Harpoon in BOL after manually entering the bearing to target. The bearing I entered was 023 dgrs, but I noticed the bearing it flew was 018 dgrs. So it was off by ~5dgrs. This was on the Caucasus map, where magnetic deviation is ~6 dgrs (I think).  So, I input a true heading, but the missile flew a magnetic heading? Anyone else see the same behavior?

Hello,

Last time we check, the harpoon launched in R/BL go straight for the target at the time of launch.

No idea if this is this the real behavior, but it feels weird as the weapon system could deduce an interception bearing (for a weapon mode that allow to select a specific moving target, it would makes sense).

The seek range is an independent setting that may mitigate this and get the harpoon back on target, but isn't related.

I believe all the aviation uses magnetic. Maybe in todays age the military uses true.

NATO uses magnetic, Russians use true because much of their landmass is up north, where magnetic variation can be large. When flying in very northern latitudes, western and NATO aircraft also switch to true.
