There are three main options, the first is to put everything on a mega floating platform, the second choice is to have the missile interceptors separated from the radar, and lastly is to combine the SPY-7 radar with existing warships equipped with Aegis systems.
For option two, the missiles inside a VLS can be mounted on a float, or a commercial vessel and lastly on a warship.
