The USS Allegan (AK-225) was a Crater-class cargo ship constructed during World War II, originally launched as SS Van Lear Black. Built by Bethlehem-Fairfield Shipyard in Baltimore, Maryland, she was laid down on December 21, 1943, and launched on January 21, 1944. The ship was acquired by the U.S. Navy under a bareboat charter on August 7, 1944, renamed Allegan, and designated AK-225 on August 12, 1944. She was converted for naval service at Baltimore by the Maryland Drydock Co. and officially commissioned on September 21, 1944. The vessel’s design prioritized cargo transport, with a focus on delivering troops, equipment, and supplies to key locations in the Pacific theater. After shakedown training in Chesapeake Bay, Allegan loaded pontoons at Davisville, Rhode Island, and departed on October 19, 1944, heading for the Philippines via the Panama Canal. She arrived at Eniwetok on November 27 and subsequently joined convoy operations en route to Leyte, arriving on December 22. Throughout late 1944 and early 1945, Allegan operated in Philippine waters, particularly around Samar, discharging cargo and assembling pontoons under constant threat from enemy air attacks. Her service in this area was notable for her resilience, as she successfully operated despite frequent enemy air raids and even helped down three enemy planes. In 1945, Allegan continued her logistical missions, moving cargo to Okinawa and supporting operations during the Battle of Okinawa. She arrived off Okinawa on May 3 and remained in the area for three months, discharging cargo and assembling pontoons amid ongoing air assaults. After departing Okinawa in August, she traveled via Saipan to Pearl Harbor, then to San Francisco. Following voyage repairs, she headed back to the East Coast, arriving in Norfolk in late October 1945. Decommissioned on November 15, 1945, at Portsmouth, Virginia, Allegan was returned to the War Shipping Administration and struck from the Navy list later that month. Her wartime service earned her one battle star, recognizing her contributions in the Pacific theater. The USS Allegan’s service exemplifies the vital logistical support provided during key operations in the Pacific during World War II.
