Aegis Ashore
https://en.wikipedia.org/wiki/Aegis_Ballistic_Missile_Defense_System#Aegis_Ashore
This is probably what they mean.
SM3 Ballistic missile interceptors.
Under construction in Poland and Romania.
SM3’s are just interceptors. Even if they could be used in a ballistic land attack mode like Russian S300 and S400, they would be lousy at it.
You understand nothing about strategic missiles and their use. Please shut up.
