Kidds will be using the same SAM (SM-2) and the SPG 60 fire control radar. The only difference is that it is using a rail launcher and it doesn't have the Aegis battle management system. Before it was decommisioned it was given the NTU (New Threat Upgrade). Those sunburns will be shut down.
Having a high speed missile also presents another problem. You need to have a very fast processor because the missile it self will barely have enough time to acquire its target once it breaks the horizon. Can it tell the difference between a ship, several clouds of chaff, a Sea Hawk helo emmiting a radar signiture of the ship, and active jamming, within 30 seconds?
US has the technology to employ missiles with such speeds but it choses not to. Why, its called greater probability of target acquisition and destruction.
