^you mean like getting s400... I haven't read of any info online for using an elm2288 to provide the cueing to the 92N6 "Grave Stone" fire-control/missile-uplink radar of the s400 system...
normally if you buy one fire unit of s400 (consisting of a 92N6 radar and a group of subordinate TELs) this would come with a 96L6 "Cheese Board" search/acquisition radar as well which would provide the cueing for the 92N6 engagement radar...
if instead we bought a whole s400 battery (ie. up to six fire units) this would come with a 91N6 "Big Bird" which can delegate up to six targets each for each of the subordinate 92N6 engagement radars...
I haven't read anything of replacing either the 96L6 or 91N6 search/acquisition radars with an elm2288... since the 92N6 engagement radar communicates with it's "controlling" search/acquisition radar via RF data links I suppose using an elm2288 would mean some sort of developmental item to bridge from the elm2288 tracks to the 92N6 data link...
