The President of the United States of America takes pleasure in presenting the Navy Distinguished Service Medal to Vice Admiral Hyman G. Rickover, United States Navy, for exceptionally meritorious and distinguished service in a position of great responsibility to the Government of the United States from 17 January 1955 to 17 January 1961 while in charge of the Naval Nuclear Propulsion Program in the Department of the Navy and in the United States Atomic Energy Commission. Through Vice Admiral Rickover’s skillful technical direction, unusual foresight, and unswerving perseverance, the United States has attained preeminence in the field of naval nuclear propulsion. His vision in the training of the crews of our nuclear powered ships, and his insistence on high engineering standards are influencing those who bear a responsibility in preparing the Navy and the Nation for the demanding and exacting trials of the nuclear and missile age. As a result of his untiring and relentless efforts, nuclear propulsion has provided us with the foundation of the new Navy – nuclear-powered submarines which have revolutionized naval offensive and defensive tactics and nuclear-powered ships free to go anywhere at any time. Nuclear propulsion, developed under his astute leadership, will take its place in history as one of the key developments profoundly affecting all the navies of the world. In addition to his major efforts in the nuclear propulsion field, Vice Admiral Rickover has made other important contributions in the field of naval engineering and has always been a source of wise counsel in matters affecting both the Navy and the national interest. His distinguished and inspiring accomplishments reflect the highest credit upon himself and the United States Naval Service.
