Through the late 1960s and early 1970s the Air Force and Army began to send qualified students to the program to obtain M.S. degrees and later staff the nuclear programs in their own organizations. In the 70's, the NESEP program (Naval Enlisted Scientific Education Program) brought a number of well qualified enlisted men into the nuclear program to earn undergraduate degrees and a number of foreign countries contributed students to earn BS, MS or PhD degrees and then return to their respective countries.
