you probably already know this, but just to clarify: the track data from spy1 includes range data as well...

will this be using essm blk-2 (ie. active/arh seekers) so it doesn't need illuminators? or will you replace the satcom in the radome at the top of the i-mast with a stir fcr (or just add stir fcr somewhere else)?

re. gun fire control: since you already have spy-1d, you can just have a similar system like the ddg-51's mk-34 gws (gun weapon system) which uses the spy-1d as it's main source for targeting data (ref: http://www.tpub.com/gunners/232.htm)...

I know it's fictional/AU but am just wondering: why are the forward spy1 panels at a higher elevation than the rear panels? are you trying to get the forward beams to clear some obstruction in the forward part of the ship? fwiw, IRL the ddg51 flight-2A rear spy1 panels were placed at a higher ...

@judah -- hello kababayan! :) I guess you've been following the progress of our (soon to be) 3 hamilton class ships... one small item: top of the foremast, all our whecs have lost their two DF/direction finding antennas (both the crossed dipole adcock and the crossed loop antennas)... sad but true ...

yup, that was the knox class ff-1070 "Downes", which served as the test ship for the 1975 at-sea testing of the TAS mk23...
