The State Department sent the embassies in Ankara and Rome the text of a draft note to be used in negotiations with both countries for formal agreements on the removal of the Jupiter missiles and their replacement with Polaris submarines operating in the Mediterranean. The dismantlement of Jupiter sites in Italy would âbegin concurrently with the arrival of the Polaris submarines in the Mediterraneanâ around April 1, while the dismantling in Turkey would begin with the arrival of the second Polaris submarine on or about April 15.
