The USS Chestnut (AN-11/YN-6) was an Aloe-class net laying ship constructed for the United States Navy during World War II. Launched on March 15, 1941, by Commercial Iron Works in Portland, Oregon, and sponsored by Mrs. W. E. Meagher, the vessel was placed into service on July 25, 1941. Initially designated YN-6, the ship was later redesignated AN-11 on January 20, 1944, reflecting its role as an auxiliary net layer. The USS Chestnut measured approximately 194 feet in length, with a beam of about 35 feet, designed specifically for deploying and maintaining anti-submarine nets to protect harbor facilities. Her primary service was to tend nets and provide harbor defense at various strategic locations across the Pacific theater. She was assigned to the 11th Naval District, operating out of San Diego, California, until June 24, 1942. In early 1943, the USS Chestnut steamed via Hawaii and Samoa to reach Efate in the New Hebrides on February 26, 1943. She conducted net tending and harbor services there and at Nouméa until December 5, 1943, with a brief overhaul at Dunedin, New Zealand. From December 13, 1943, she operated in the Solomon Islands, performing cargo, salvage, and net repair duties until August 29, 1944. Between September and October 1944, she dismantled and removed nets from Havannah Harbor, Efate, before undergoing repairs in Australia. Following repairs, Chestnut returned to Nouméa and later moved to Ulithi, where she handled net and mooring operations, including a brief period at the Kossol Roads seaplane base in Palau. She remained at Ulithi until June 19, 1945, then proceeded to Guam, where she served until September. She completed her service with a return trip to the U.S. West Coast, arriving at San Pedro, Los Angeles, on October 13, 1945. The USS Chestnut was placed out of commission and placed in reserve on September 7, 1946, at Bremerton, Washington. Throughout her service, the USS Chestnut played a vital role in harbor defense, safeguarding Allied naval and merchant vessels against submarine threats in critical Pacific locations during the war. Her work in deploying, maintaining, and removing defensive nets was a key component of naval harbor security during WWII.
