The USS Sagittarius (AKN-2) was an S-class Indus net cargo ship employed by the United States Navy during World War II. Originally laid down as a liberty ship, SS J. Fred Essary, on 8 November 1943 by Bethlehem-Fairfield Shipyard in Baltimore, Maryland, she was launched on 30 November 1943. Sponsored by Mrs. J. Fred Essary, she was acquired by the Navy through a bare-boat charter on 8 December 1943 and converted into a net cargo ship, receiving the designation AKN-2. She was officially commissioned on 18 March 1944. Constructed to support harbor defense with specialized net-laying capabilities, Sagittarius's service included extensive operations across the Pacific theater. After shakedown in Chesapeake Bay, she traveled through the Panama Canal to San Diego, then proceeded to Pearl Harbor and the Marianas. At Saipan and Tinian, she installed harbor defense nets, crucial for protecting Allied ships from enemy submarines and surface threats. Her deployment extended to Nouméa, New Caledonia, and Ulithi, where she laid additional defensive nets from mid-October to mid-November. In 1945, Sagittarius continued her vital role in the Pacific, serving as the flagship of TU 52.8.3 at Ulithi. She participated in the Okinawa campaign, arriving at Hagushi anchorage on 18 April and joining Task Force 51. Her operations were marked by frequent enemy air attacks, including kamikaze assaults. Notably, she shot down her first kamikaze on 28 April and a second on 27 May, demonstrating her active engagement in combat defense. Despite ongoing threats, she maintained her net-laying duties until late May. After the Okinawa operations, she experienced an incident when she exploded a drifting Japanese mine near Saipan on 4 June. Later, she returned to Pearl Harbor and conducted additional net operations at Ulithi and Saipan before heading back to the United States. Following Japan's surrender, she resumed transport duties and returned to San Francisco in November 1945. Decommissioned on 16 January 1946 at Norfolk, Sagittarius was struck from the Navy List shortly thereafter and was scrapped in 1972. Her service earned her two battle stars, reflecting her contributions during critical Pacific campaigns. The USS Sagittarius stands as a notable example of auxiliary naval vessels vital to harbor defense and fleet operations during World War II.
