Ok, mission completed, thank you
Unfortunatelly i was detected quite fast, so taking photo was little complicated. I had to do this under ASROC attack
Bug:
- sinking Belgrano didn't completed critical goal trigger
My suggestions:
1. Skipjack is little too obsolete to this role. But its hard to find good substitute in RA. In my opinion best would be Rubis
2. Sea State 4 is too high. On historical pictures waves werent so high.
3. Iowa is too big warship for Belgrano role. I suggest De Ruyter (Chilean navy)
4. Because Kill trigger didn't completed (when i sunk Iowa) all rest events didn't happened (i saw it in mission editor after game)
5. After start player should be informed to recive radio message. In my game i recived message after taking photo
6. Trigger #2 Report contact was completed without reciving message. So when i checked it in mission status, i thought i can sink Belgrano (new goal appeared)
After sinking Belgrano i was waiting for new orders but goal wasn't complete. So i just for fun killed 2 Gearing class
Btw RA 1.50 should be released soon. Crazy Ivan will add few "old" US ships:

maybe this ships will better fit to this mission.
Overal mission is quite good for playing. I've spend good time in this scenario. Im waiting for improved version.
P.S. sorry for my aggresive style of playing - but its from MP sessions where players havent time for pretending whole in water.
"kill or be killed"
