The USS Aylwin (Destroyer No. 47/DD-47) was the lead vessel of the Aylwin-class destroyers built for the United States Navy prior to World War I. Laid down by William Cramp & Sons of Philadelphia, her keel was established on May 7, 1912, and she was launched on November 23, 1912, sponsored by Mrs. Joseph Wright Powell. The ship measured approximately 305 feet 3 inches (93.04 meters) in length, with a beam of 30 feet 4 inches (9.25 meters), and a draft of 9 feet 5 inches (2.87 meters). Her standard displacement was 1,036 long tons (1,053 tonnes), increasing to 1,235 long tons (1,255 tonnes) at full load. Aylwin was powered by two steam turbines and four oil-fired boilers, generating about 16,000 shaft horsepower, which was designed to propel her at a top speed of 29.5 knots (33.9 mph). However, she failed to reach this contracted speed during builder's trials in August 1913. Her armament comprised four 4-inch (100 mm)/50 caliber guns and eight 18-inch (450 mm) torpedo tubes, making her a formidable opponent in early 20th-century naval combat. Commissioned in January 1914, Aylwin's early service included exercises and patrols along the North Carolina coast. Notably, on April 6, 1914, an explosion in her No. 1 fire room caused the deaths of two sailors; the ship was heavily damaged but remained afloat. She was out of commission for repairs until May 1915, after which she rejoined the Atlantic Fleet. During World War I, Aylwin conducted patrols from Queenstown, Ireland, and Plymouth, engaging in anti-submarine operations and experimental work with Reginald Fessenden. She participated in rescue operations following encounters with German U-boat U-53, rescuing survivors from the sinking of ships like Stephano. Following the war, Aylwin remained in European waters, inspecting German ports and assisting with the repatriation of prisoners and citizens. She returned to the United States in June 1919, was placed in reserve, and was decommissioned at Philadelphia in February 1921. She was later renamed DD-47 in 1933, struck from the Naval Vessel Register in 1935, and ordered scrapped under the terms of the London Naval Treaty. The USS Aylwin served as a significant early 20th-century destroyer, participating in key operations during wartime and embodying the naval technology and strategy of her era.
