Just imagine a future port visit mistakes Our Canberra for their Canberra. They are expecting a couple of dozen Americans and instead get a couple of hundred Aussies. Could be the making of an international incident after their pubs are drunk dry.Well we could have a repeat of what happened in the Korean War when HMAS Bataan escorted the USS Bataan. Don't know if naming one of the Frigates HMAS Washington would be that great an idea.
