Went to work on the mast first since that was the biggest problem here (followed by the hull shape and ridiculous length). I decided to try out if something more along the lines of the Schelde Combatant's radar would work. As in; a rotating volume search radar in an enclosed housing. Also, I hoped that maybe something along the lines of an enlarged TRS-4D (not Thales, I know, but maybe an AU Thales?) would provide SMART-L capability in a small package. I do hope this works. It's worth giving a try.
From top to bottom; a Mirador at the top, some nav lights below that, ECM\ESM suite, non-rotating IFF. Below that it gets exiting; the empty space there contains the volume search radar, in a very simmilar way to how the Schelde combatant had the SMART-S there. Also in this room are the Seastar, Gatekeepers, and a Colds NG laser warner (also not Thales, but I couldn't find a Thales equivalent).
The level below that contains everyone's favorite radar director; APAR. And also some more nav-lights and and four faces of the ICAS.
Then finally at the bottom level we have the flat-panel deriative of Sirius, the other sixteen ICAS faces, and four satcoms. There is also a small below-deck room for cooling\processing, as this might not all fit in the mast itself.
The mast is a little larger than I-mast 500 in every dimension, but not out of the ballpark. Chances are that all kinds of shit is wrong with this...
