f18 AGM 88C attacking dead targets in PB mode

[Minijohn]

While testing during a mission build where I wished to use AGM 88C against a ship target, I found that when using UNIT EMISSIONS OFF in the ME, when attacking targets in the F18 using AGM88C in PB mode the missiles would attack a target that had had it's emissions turned off . Testing further I discovered that even if you forced the target to be destroyed by an AGM88C hit and re-attacked using PB mode the AGM88C would attempt to attack the dead target, even if another unit of the same type was available. 

Testing further, I set two ships up in the ME that when hit would explode and effectively be killed,  I then attacked the  two ships in TOO MODE and destroyed the ships, then I carried out an attack using PB mode and the missiles attacked the location of one of the dead ships. 

For whatever reason when using UNIT EMISSIONS OFF, or DESTROYING THE TARGET when attacking two ship targets of the same type the second and subsequent missiles will attack the first target only and ignore any other valid targets.

The test mission I used is below and I used the following procedures.

Test One

1/ Attacked targets using PB Mode One Missile only(Targets are set to explode and die when hit)

2/ After missile hits, attacked again using PB Mode ( Missile will attack first target)

My result, second missile will attack first target which is dead

 

Test Two

1/ Attacked both targets in TOO mode. (Targets are set to explode and die when hit)

2/ While missiles in flight set up for attack in PB mode, when first missiles hit, then fired on targets.

 

My results, missile fired in PB mode will hit one of the dead targets.

In TOO Mode system is working correctly as no valid targets are available to attack

I am not sure I understand the issue, in PB (Pre-Briefed) the missile is being sent at a pre-set location, it is not required to be emitting, the position is known and marked with a target point.

The PB destination in the mission is in the middle of two ships 3nm apart. When both ships have been hit (dead) and then a PB HARM is launched between them, the PB missile steers toward one of the ships as if it's emitting. The PB missiles are attacking a dead non-emitting unit 1.5nm from the PB destination when the unit hasn't been emitting or alive since before the PB launches.

Thanks, I will take a look

I agree with nearly everything you say, but for the missile to engage a target the target has to be emitting at some point. If it is not emitting the 88C will just overfly the target area. The problem I had was that you could succesfully attack two targets using PB mode, and then attack the same targets again and the missile would strike one of the dead targets. This is NOT correct, if the target is not emmitting then the HARM has nothing to lock onto

Yeah, CEP is not modelled in basically any guided ammunition in DCS
