I might be wrong but.... do you have any idea what SPY-1 does? what it is? how it works?
anyways, gonna tell you this: it has nothing to do with tracking, it is an search radar. tracking is done by directors or phased array radars or similar stuff. you can do tracking with SPY-1, but it is not designed to do so, and it does not operationally (as far as I know/remember)
What.
Anyway, not bad for a modern battleship! Although a modern battleship is a lot like the Star Wars prequels!
