Consistent with the concerns about target coverage, the plan for Polaris patrols required the presence of at least one submarine in the Mediterranean. The overlapping patrols would begin when the U.S.S. Sam Houston entered the Mediterranean on March 28, followed by the U.S.S. John Marshall on April 10, and the U.S.S. Ethan Allen on 1 June. The Sam Houston could make a port call in Turkey, but the stopover had to occur when another submarine was in the Mediterranean. Taylor recommended the port of Glock as the site of a two-day visit, one day for a visit by officials and the second for a “daylight indoctrination cruise by designated observers.” The latter would be barred from sensitive “spaces” used for communications and nuclear propulsion.

The Joint Staff prepared a detailed and lengthy report in response to a request from the Defense Department’s Office of International Security Affairs for an “outline plan for withdrawal and complete disposition” of the Jupiter missiles. A number of options were considered and rejected, including other military uses, offering the Jupiters to other agencies as a space booster, storing the missiles, and destroying them “without reclamation.” As there was “no identifiable requirement for the missiles,” the most appropriate option was “promptly dismantling and removing [them] from operational launch site.” While the warheads should be speedily returned to the United States, other useful components could be reclaimed, and the rest could be salvaged. The process would prevent the loss of high value components that were still usable, such as rocket motors, fueling trailers, and electronic devices. Such an outcome required decisions on the final disposition of Jupiter assets.

This message conveyed several decisions that McNamara had detailed in a memorandum on “The Replacement of Jupiter and Related Matters.” One Sergeant missile battalion would be deployed in Italy to replace Corporal missiles. The U.S. would not transfer to Italy “operational responsibilities” for nuclear weapons currently deployed to the Southern European Task Force [SETAF]. The U.S. would not deploy Pershing missiles to Italy. Planning would begin for the assignment of three Polaris submarines to the Mediterranean beginning April 1, 1963. Finally, plans would be made to deliver 14 104-G’s to Turkey during April 1963.
