AGM 84 D Problems

I have been trying out the new AGM 84D SEA RADAR targeting and have experienced a few that I consider to be bugs, but acknowledge that the features I am trying to use may not have been fully implemented,

 

Basically there are three areas that I am having problem with:-

 

1. Missile flight height, I have tried numerous different times with different flight heights, in the track file I release the missiles at around 1500 to 2000 AMSL with flight set to LOW. The missiles drop and adopt a height of flight but this seems much too high, they continue at this height until dropping to skim height. In other tests I have done missiles launched from a much higher altitude simply crash into the sea.

2. Setting SEEK, it seems that this function simply does not work, no matter what I set, the missiles seem to randomly select a target and home in on that.

3. Missiles aim at “phantom” targets, in the last couple of attacks on the track file the missiles attack a target that was previously destroyed. I even changed aircraft to check that it was not a carry over somehow from my previous attacks.

 

I realise that items 1 and 2 may not have, as yet, been fully implemented. But item 3 is quite annoying, when you launch on a properly designated target, to have the missiles simply go after a previously destroyed target.

 

On a side note, I have been having problems with my convoys in the mission refusing to start to move at mission start or stopping after being attacked and not restarting if a ship is sunk. Convoy 1-3 in the track file is a prime example. I have tried various combinations of ships and find that either ALL of the ships fail to move or just one ship moves and the rest do not. Any ideas?.

1. for flight height of harpoons and slams. low is 5000ft, med is 15000ft and high is 25000ft. You should be releasing them from above the height that you select. ie. don't release below 15000ft if it is set to medium.  At times I have observed that releasing them lower than their programmed height will cause them to attempt a climb to that height and they will stall out. 
 
Flight height is the altitude the missile will fly while cruising to its intended search area and while searching. Only after it has a valid target will it attempt to skim the water


2. the seeker setting tells the missile at what distance from the selected target to turn on its seeker. Unfortunately, this does not prevent it from seeking an unintended target once it activates. It is also possible currently for the missile to be to high when the seeker turns on to see the intended target and to continue flying past it either until it detonates or into an unintended target. 
per the hornet manual for DCS, seeker modes are as follows
• SML. 10,000 meters before target location
• MED. 20,000 meters before target location
• LRG. 30,000 meters before target location

so 10km (5.4nm), 20km(10.8nm), and 30km(16.2nm)
Once that seeker turns on. It will go after the first ship it sees. 

 

3. Dead ships still exist. Telling the harpoon to go after a target location is only telling it to go to it and start looking. The missile doesn't have any way of knowing that the ship it sees is already dead and sinking. a ship is a ship in its seeker.

Harpoons are not designed as precision strike weapons. They were not intended for picking out a target within a group of non targets. For that I would suggest the Walleye, Slam, or laser guided munitions.
