Hi I've just been going through US Navy Shipboard Antennas and in the Mk 92 FCS the Dutch eggpod radar (Signall WM-25) contains two antennas inside the egg. On top is a dish shapped tracking radar and below it a rotating search radar. Both antennas are driven by the same radar. This is similar to the Phalanx radar but with the search radar on top. So in the parts sheet here just the WM-25 is needed for gunfire control. The second and seperate dish antenna is the Separate Tracking Illumination Radar (STIR) which is used for long range tracking (cued by the SPS-49) and SM-1 missile illumination.
Thanks for the comments. I was aware of this mistake, and it's corrected in my head and on the sheet on my home computer, but I haven't gotten around to uploading the revised version. It's on my unpleasantly-long list of things to do. If I fix one thing I really want to fix them all, and there is a bevy of errors on this parts sheet, so I keep getting discouraged... I may start uploading things in blocks instead of an all-in-one.
