Welcome to Dave Does History, where we surface the forgotten stories beneath the waves. Today, we turn our periscope toward the USS Theodore Roosevelt, SSBN-600, a submarine that carried the name of a president who believed in speaking softly and carrying a big stick. Launched in 1959 at Mare Island, she embodied the dawn of a new kind of strength, one that stayed hidden under the sea but kept the peace through quiet vigilance. For two decades, her crews sailed in silence, guardians of the Cold War’s uneasy calm. This is the story of the boat that bore Roosevelt’s name, and of the men who kept watch in the deep so that the world above might never see the fire they carried.
