The USS K-1 (SS-32), originally named Haddock, was the lead vessel of her class of United States Navy submarines. Constructed by the Fore River Shipbuilding Company in Quincy, Massachusetts, her keel was laid on February 20, 1912, as a subcontract for the Electric Boat Company. Launched on September 3, 1913, and commissioned on March 17, 1914, K-1 measured approximately 153 feet 7 inches (46.8 meters) in length, with a beam of 16 feet 8 inches (5.1 meters) and a mean draft of 13 feet 1 inch (4.0 meters). She displaced 451 long tons (458 metric tons) on the surface and 527 long tons (535 metric tons) submerged. Her operational diving depth was 200 feet (61 meters). K-1 was powered on the surface by two 475-horsepower NELSECO diesel engines, each driving a propeller, allowing her to reach speeds of up to 14 knots (26 km/h). When submerged, she used electric motors producing 170 horsepower, achieving a submerged speed of 10.5 knots (19.4 km/h). Her range was 3,150 nautical miles (5,830 km) at 11 knots on the surface, and she could operate 120 nautical miles (220 km) at 5 knots underwater. Armed with four 18-inch torpedo tubes in the bow and carrying four reloads for a total of eight torpedoes, she was designed for offensive submarine warfare. Throughout her service, K-1 operated primarily along the Atlantic coast, including patrols off Rhode Island, Massachusetts, and Florida, and conducted training, development, and patrol missions during World War I. Notably, she patrolled in the Azores during the war, from Ponta Delgada and Horta, aimed at protecting Allied shipping and denying U-boat activity in those waters. She was deployed to European waters in 1917, operating from Ponta Delgada, and conducted routine patrols until the end of hostilities, although she reportedly did not encounter enemy U-boats. Post-war, K-1 returned to U.S. waters, undergoing repairs and participating in exercises and maneuvers along the East Coast. She was re-designated SS-32 in 1921 and continued operations from bases such as Hampton Roads and New London until her decommissioning on March 9, 1923. Stricken from the Naval Vessel Register in December 1930, she was sold for scrap in June 1931. The USS K-1 played a significant role as the first of her class, representing early U.S. naval submarine development and operational deployment during World War I.
