Career
H20 was a British H class submarine built by Fore River Yard of Quincy, Massachusetts. She was launched on 25 August 1915. Because the United States was neutral (having not yet entered World War I), H20 along with sister ships HMS H11, HMS H12, HMS H13, HMS H14, HMS H15, HMS H16, HMS H17, HMS H18, and HMS H19 were all interned by the United States government. As a result, H20 was never commissioned into the Royal Navy. Instead, she and H13, H16, H17, H18, and H19 were transferred to the Chilean Navy as partial recompensation for the appropriation of two 28,000-ton dreadnoughts (CHILEAN BATTLESHIP Almirante Latorre and CHILEAN BATTLESHIP Almirante Cochrane). Originally named H6 when turned over to Chile in 1917, she was renamed Fresia in 1924. She served with the Chilean Navy until she was stricken in 1945.
