As of October 2011, only the Delta IV remains in production. However, previously built hardware for five more Delta II vehicles exist and are available for purchase to launch customers. They would likely launch from Vandenberg AFB on polar-orbit missions, according to NASA & rocket manufacturer United Launch Alliance
