ok i have tried and tried and tried to find this FINAL ship that I need for the accolade, I know its in the Kelvani Belt, I know its patrol route, Ive looked at Wiki and a few other guides and still this ship doesnt want to spawn...
I just want to know if this ship has actually been deleted as part of the many patches been done and for some reason it has been lost to blame of patches upon patches
Na... it's just rare... If you find the "route" map on STO wiki, and look at it, it will warp in at 11 o'clock and fly that path, then warp out.
You have to be in a mission map (It dosent seem to appear if you just warp into the regular map), and then wait.
Fly to 11 o'clock and fly counter clockwise following the patrol route. If you fly all the way, and it is not there, you have the option to wait for how ever long you have the patience for (I waited for a little over an hour).
The key to finding it is to take the Aid The Deferi mission, then warp into the Kelvani Belt. Ignore anything that's going on inside the map, then go to the patrol route. If it's not there, warp out, then wait five minutes for the map to reset. Then try again.
Also, if the ship IS there, you'll see an enemy reading MUCH farther out than you'd normally see on your map/mini-map
As soon as you enter the map, you *WILL* see the Istapp on your map, no matter where you are from it. If the other two ships are any indication, they will show up on your mini-map immediately without exception.

All the info you're looking for is there in either link or text form. But Basically, The Istapp is one of 3 ships in the Dereri Sector that you have to destroy to get an accolade. Finding the ships first is by rare chance.
