Following the departure of the Navy, and the awarding of JUPITER control to the Air Force, the possibility of a configuration change arose, since the system would  now be land-based exclusively. However, development progress had reached a technical point where changes of great scope were unnecessary. So the length of  the missile was increased by only two feet to an over-all length of 60 feet. The diameter remained the same, as did the range. Some changes were made, such as  the elimination of the inertial fuze in the warhead section, leaving the proximity and impact fuzes; and the elimination of the radio-inertial guidance scheme from  the program, leaving only the all-inertial system 62 .
