By late January, the negotiations with Turkey were bogged down, with Defense Minister Sancar asking for a Turkish military presence on the Polaris submarines as well as delivery of nuclear weapons for the F-100 Super Sabres before the Jupiters were replaced. Without a formal agreement on the Jupiters, the U.S. government held back from a decision on another matter: the delivery of F-104G fighter-bombers. Nevertheless, Defense Department officials approved a decision to “provide first available aircraft” in April 1963, which was necessary to authorize the Air Force’s “preliminary preparatory actions.” The U.S. would preserve its “bargaining position” by informing Turkey in writing that an “accelerated delivery date will become firm upon satisfactory conclusion of current US/Turkey negotiations.”
