I had a chance to spend some time on HMAS PERTH which is fitted with the new CEAFAR/CEAMOUNT radars. They don’t weigh much but the performance is outstanding. Better yet it is very easily scalled up (they are modular so just add more tiles).
As Dundee described, the new Australian radar and the Israeli EL/M-2248 are excellent for lighter ships if you are looking primarily for anti-air and anti-cruise missile capability.
What the Aussies did with their Perrys is something we should have done long ago. The Aussies will not have large numbers in their new vessels and fleet, but with the Canberras and the new Air Defense DDGs they will be very, very good.
Not exactly the impression given by the Emperor Dalek on the 02 deck
But you're right. When Huntington Ingalls pitched their Patrol Frigate 4921 for the SEA 1180 Offshore Combatant Vessel (they're dreaming) they put CEAFAR into a tiny chapeau right on the masttop.
