From 1959 to 1964 a handful of American submarines armed with the Regulus cruise missile provided a forward deployed nuclear deterrent for the United States. Today only USS Growler (SSG-577) remains, docked in New York City and open to the public as a museum. Author Robert K. Harmouth served in Growler during the time when she operated on deterrence patrols off the Soviet Union's Pacific coast. In Up From the The Return, he has created a fascinating combination of history and personal recollection of those days.
