The USS Artemis (SP-593) was originally built as the steam yacht Cristina, a steel-hulled vessel designed for luxury cruising. Launched in 1911 and completed in 1912 by Pusey and Jones Co. in Wilmington, Delaware, the yacht measured approximately 161 feet 3 inches (49.1 meters) in length, with a beam of 26 feet 3 inches (8 meters) and a draft of about 15 feet (4.6 meters). Her construction featured a steel hull, powered by two Almay boilers that supplied steam to two triple-expansion steam engines, generating around 1,400 indicated horsepower. This propulsion enabled her to reach speeds of approximately 12 knots (14 mph), with a cruising range of 1,800 nautical miles at 10 knots. The vessel's overall displacement was 456 gross tons, with a net tonnage of 272. Initially owned by Frederick C. Fletcher of Boston, Cristina was later purchased in 1916 by Cleveland philanthropist John Long Severance, who renamed her Artemis. The yacht was registered with the U.S. Official Number 209890 and the signal LCJW. In the brief period before the U.S. entered World War I, Artemis was listed at the New York Yacht Club. In mid-1917, the U.S. Navy acquired Artemis for $181,300 to serve as a patrol vessel during World War I. She was delivered on July 4, 1917, and commissioned as USS Artemis (SP-593) on November 1, after conversion at Shewan's Shipyard in Brooklyn. Armed with two 3-inch guns, she was tasked with escorting convoys, towing French subchasers to Europe, and patrolling for German submarines. Her notable service included escorting convoys between Gibraltar and North Africa, engaging in anti-submarine patrols, and participating in convoy defense operations along the Spanish coast. The vessel was renamed Arcturus in February 1918, following a Navy order. After the war, Artemis was decommissioned in May 1919, transferred to the U.S. Coast and Geodetic Survey, and returned to civilian service. She was sold in 1924, briefly owned by British subjects, and later operated by a Honduran company. Her maritime career ended when she burned and sank off Key West, Florida, in 1927. Throughout her service, Artemis/Arcturus played a significant role in early 20th-century naval patrols, especially in anti-submarine operations during World War I.
