Yeah I did contemplate Type 1022 briefly but came to the same conclusion as you did, but it basically is the same radar set up as the Type 22's and 23's, the main difference is that my ship lacks some of the ECM found on those ships and has SPS-49. The way I figure it is that a valid case can be made for both having it and not having it, but by not having it the ship would lose some capability (how much it would lose and whether this would be important is debatable) and, more importantly, I'd have a mast that I wouldn't know what to do with
A British ship with a US radar is not without precedent - although it doesn't seem to have happened too much recently - but I would like to retain some kind of long range search at least, if not SPS-49 specifically. I think I'll go off and do some research...
