This early twentieth-century photograph shows the U.S. Navy submarine Shark (SS-8) running on the surface, her low hull awash and crew standing exposed on deck near the vessel's ventilation tubes and signal mast. Vessels like Shark represented the U.S. Navy's first generation of operational submarines, entering service in the years following the Spanish-American War as the fleet modernized. This snapshot was preserved in the USS Columbia photograph album, documenting a chance encounter between the cruiser and the fledgling submarine service. Project: 218597
