The USS Menkar (AK-123) was a Crater-class cargo ship constructed during World War II, converted from a Liberty Ship. She was laid down on November 17, 1943, by the St. Johns River Shipbuilding Company in Jacksonville, Florida, under a Maritime Commission contract (MC hull 1218). Launched on December 31, 1943, and sponsored by Mrs. Cora E. Owens, she was initially named after John White, an early North Carolina settler and explorer associated with the Roanoke Colony. The ship was acquired by the U.S. Navy on January 17, 1944, under a bareboat charter, and renamed Menkar, after the second-brightest star in the constellation Cetus. After a brief period of temporary commissioning to transfer her to Miami, she was decommissioned on January 22 for conversion by Dade Drydock Co. and re-commissioned on June 2, 1944. Menkar’s primary role was as a cargo transporter, delivering troops, supplies, and equipment to crucial locations in the Pacific Theater. She sailed to Norfolk, Virginia, for shakedown, then headed through the Panama Canal Zone to join the Pacific Fleet. In October 1944, she was transferred to the U.S. Coast Guard for Long Range Navigation (LORAN) station construction, marking her as part of the vital infrastructure supporting Allied operations. She unloaded cargo at Saipan, Guam, and Ulithi, contributing significantly to the establishment of LORAN stations, which played a crucial role in navigation during the Pacific campaigns, including Iwo Jima and Okinawa. Menkar’s service included delivering materials for LORAN stations across the Marianas, Palau, and Japan, and supporting the construction of the Iwo Jima–Tokyo–Okinawa chain. She engaged in combat-like conditions, notably shooting down an enemy aircraft during operations near Okinawa on May 18, 1945. After the war ended, she continued LORAN operations until her return to the United States, arriving in San Francisco on March 3, 1946. She was decommissioned on April 15, 1946, transferred back to the War Shipping Administration, and renamed John White. The vessel was sold for scrapping in 1947 and was withdrawn from service in 1962. Menkar's operational history underscores her significance in supporting critical wartime navigation and logistical efforts in the Pacific.
