Sink Cargo Ship Instant Action mission

[sthompson]

I've recently returned to the JF after having it on the shelf for quite a while. When I tried using it previously I was frustrated by problems with the antiship missiles, and I gather that those are working much better now. So recently I tried the "Sink Cargo Ship" instant action mission on the Syria map. I'm having trouble figuring out how to set a SPI for the MITL launch. There is no waypoint in the vicinity of the target ship, nor is there a PP target waypoint. So I've tried designating the target using radar (SEA1 mode). That requires a pop-up since there is a big hill creating a radar shadow from the launch point if I stay low. Popping up is getting me lots of attention from SAMs and two F-16s, but when I go down low again after launch the missile seems to lose guidance. So do I need to maintain a constant radar lock to attack in this mode? Is there some better way to provide guidance to the missile? I can't find a video of this mission online to provide some clues.  The briefing mentions pre-planned RP points, but no preplanned target. Any tips will be appreciated.

Also, if I change SPI after missile launch does the missile still guide to the original target point. (This is in DIR mode with target set to default setting of 40, i.e. SPI).

Edit: I finally got this to work. First I learned that I need to launch in MAN mode. Then the missile will track in whatever direction it was going when it reached the last RP in the sequence. However I discovered the the mission had two RP points designated as RP4. This meant that there was no RP3 and it resulted in the missile flying towards the beach instead of the target area when it reached RP4. I fixed RP3 in the mission editor and finally was able to make things work.

Found solution to original problem.

Disclaimer: I didn’t play this mission. 

 

MITL Guidance is only possible and required on the CM-802AKG ( The cruise missile version), not on the CM-802AK. 

If you are using the AK Version (which is the dedicated anti ship version), once it is on its way it does not require a constant radar lock, its fire and forget. So, if you change the SPI after Launch, the AK does not care or know that. It’s flying where the SPI was upon launch, activate its radar a few km (10?20?) before and look for a target in the pre programmed size (SML, MED, LAR) 

 

You could set RPs (Route points) to get around the island. The last RP should be where the target is supposed to be, as this denotes the search area for the AKs onboard radar.
