hmm you will need large phased arrays then..... and may I refer to the US members now? my knowledge to this kind of stuff is limited, if you used thales I could help a bit.....
Thales has Herakles which is designed to guide Aster. I'm getting ready to switch over to SM-6 ERAM which doesn't need directors, so newer radar is desirable to go along with it. I chose the present drawing, because it looks something like APAR, in general outline, and will give my vessels a somewhat uniform appearance. Being able to guide ESSM is also of great importance.
Now, the new system doesn't have to be as capable as the APAR/S1850M combo. I'm mainly needing it for General Purpose Frigates, and to hopefully squeeze some version of it onto my corvettes, not to mention an as-of-yet-undesigned patrol frigate.
