The USS Passaic (YN-113/AN-87) was a Cohoes-class net laying ship constructed for the United States Navy during World War II. Built by the Leathem D. Smith Shipbuilding Company in Sturgeon Bay, Wisconsin, she was laid down on April 25, 1944, and launched on June 29, 1944. The ship was sponsored by Mrs. Sam H. North and was commissioned on March 6, 1945. Originally designated YN-113, she was redesignated as AN-87 on January 17, 1944, reflecting her role as a net laying and tending vessel. Constructed to serve primarily in the Pacific Theater, USS Passaic was tasked with maintaining and recovering anti-submarine nets, a critical function for protecting Allied naval and merchant vessels during the final months of World War II. Her operational service was concentrated in the Pacific Ocean, where she supported U.S. naval efforts by ensuring the integrity of defensive net systems. After the conclusion of hostilities, USS Passaic remained at Pearl Harbor, Hawaii, until 1947, when she moved to San Diego, California. She was decommissioned in March 1947 and placed in reserve, remaining inactive at San Diego until July 1963. Subsequently, she was transferred to the U.S. Maritime Administration and laid up at Suisun Bay with the National Defense Reserve Fleet. In September 1976, the vessel was sold to the Dominican Republic and renamed Calderas (P209), serving as a patrol vessel. As of 2007, Calderas was still active in the Dominican Navy, exemplifying the vessel’s longevity and continued maritime utility beyond her initial military purpose. The USS Passaic's service highlights the important but often overlooked role of auxiliary ships like net layers in naval defense during and after World War II.
